Description Light source connector, light emitting device, patterned conductor, and method for manufacturing light source connector

The present invention relates to a light source connected body formed by electrically connecting a plurality of light sources, a light emitting device using such a light source connected body, a patterned conductor for forming the light source connected body, and a manufacturing of the light source connected body. About the method. Background art

Light-emitting devices having a configuration in which a number of light sources are arranged in a row on the surface of a holder are used not only for lighting but also for advertising, decoration, and signage. To form this type of illuminator device, for example, a gun-shaped LED light source with a lead wire, a through hole into which the lead wire of this light source is inserted, and a conductor for supplying power to the light source It is conceivable to use a printed circuit board on which a pattern is formed, and to connect the conductor pattern of the printed circuit board and the lead wire of the light source by one-piece soldering.

However, in such a configuration using a printed circuit board as the holder for the light source, although there is a cost advantage in the case of mass production, a small number of various types with different light source connection patterns and arrangements are manufactured. In such a case, there is a disadvantage that the cost increases. Furthermore, printed circuit boards are exposed to high temperatures due to contact with molten solder during soldering, which is not desirable for heat-sensitive LEDs. In addition, solder usually contains lead, and its use requires environmental measures. Although the use of lead-free solder is conceivable, it is not only expensive but also has a higher melting point than ordinary solder, so the effect of heat on LEDs becomes even more problematic. Furthermore, on the printed circuit board, It is difficult to deal with the case where a light source is arranged. If the light source is connected via a flexible conductive wire, the connection is troublesome, resulting in a disadvantage that the cost increases. In addition, the printed circuit board has a problem that it is extremely difficult to recycle it when it is no longer needed because the wiring is integrated with the support plate.

As a light emitting module that does not use a printed circuit board and solder, Japanese Patent Application Laid-Open No. Hei 7-106634 describes that a plurality of LEDs are connected between an anode bus bar and a cathode bus bar by mechanical coupling connection. Is disclosed. Also, Japanese Patent Application Laid-Open No. H08-3161631 discloses that a plurality of bus bar pairs, a plurality of LEDs mounted on each bus bar pair, and an electrical and mechanical connection between adjacent bus bar pairs. There is disclosed a light emitting module that includes a flexible joint coupled to the light emitting device and facilitates three-dimensional molding. However, in the inventions disclosed in these publications, there is no disclosure of a light source connection body in which various light source connection patterns can be easily selected and which can be manufactured with high production efficiency, and a method of manufacturing the same. Disclosure of the invention

The present invention has been made to solve the above-mentioned problems of the prior art, and a main object of the present invention is to provide a plurality of light sources that can be manufactured efficiently and at low cost without using a printed circuit board. An object of the present invention is to provide a light source connected body having the same and a method for manufacturing the same.

A second object of the present invention is to provide a light source assembly capable of eliminating or greatly reducing the amount of solder used, and a method of manufacturing the same.

A third object of the present invention is to provide a light source assembly capable of easily coping with various arrangements of light sources, and a method for manufacturing the same. A fourth object of the present invention is to provide a light source assembly as described above using a chip type LED as a light source, and a method for manufacturing the same.

A fifth object of the present invention is to provide a light-emitting device using the above-described light source connector.

A sixth object of the present invention is to provide a tape-shaped conductor that can be used to form the above-described light source connector.

According to one aspect of the present invention, there is provided a light source assembly in which a plurality of light sources are electrically connected, wherein the light source assembly is configured to connect a plurality of the light sources. A connection conductor structure extending in a direction in which the light sources are arranged, wherein the connection conductor structure is formed by cutting off a required portion of a substantially flat patterned conductor on which a predetermined pattern is formed. A special light source assembly is provided. The patterned conductor can be formed by pressing a conductive flat plate material. According to this, the light source connector can be formed without using a printed circuit board, so that solder used for connection with the printed circuit board can be eliminated, and there is no need to pay attention to environmental pollution. No risk of LED damage due to heat during soldering. Also, by changing the cut portion of the patterned conductor, it is possible to form a connection conductor structure having various light source connection patterns on a single production line using the same patterned conductor. Even when a small number of light source connected bodies are manufactured in small quantities, they can be manufactured efficiently and at low cost. In addition, when the patterned conductor is formed from a conductive flat plate material, it can be appropriately deformed into a required shape by giving appropriate flexibility, and it can be used in various arrangements of light sources. It can be easily handled. Furthermore, since no printed circuit board is used, recycling when it becomes unnecessary is easy. In addition, if the patterned conductor is in the form of a long tape, it can be transported on a production line while mounting a light source, pressing, etc. Therefore, the light source connected body can be continuously produced, which is preferable. By cutting the patterned conductor into an appropriate length, it is possible to easily obtain a light source connected body having a desired length.

According to one embodiment of the present invention, the plurality of light sources include a chip LED, and a socket for mounting the chip LED is attached to the connection conductor structure by insert molding. Typically, the socket has a bottom wall and side walls to define a cavity having an opening at the top, and the chip-type LED is housed in this cavity. In this way, even when a chip-type LED having no lead wire is used as the light source, it is possible to easily attach the chip-type LED to the connection conductor structure and obtain a light source connected body. Become.

Preferably, a hole is provided in the bottom wall of the socket, from which the LED mounted on the socket can be pushed to remove the LED from the socket. In this way, a failed LED can be quickly replaced with a working LED. Also, a part of the connection conductor structure is exposed in the cavity of the socket, and the chip-type LED comes into contact with the electrical terminals of the chip-type LED with the chip-type LED mounted on the socket. It is preferable from the viewpoint of realizing quick mounting to the socket. More preferably, a portion of the connection conductor structure exposed in the cavity of the socket has a projection for contacting an electric terminal of the LED. By doing so, the electrical connection between the LED and the connection conductor can be further ensured. Also, if a part of the connection conductor structure is bent so as to engage with the LED mounted on the socket and prevent the LED from dropping out of the socket, if the light source connector is mounted upside down, Is also preferable because the LED does not drop off undesirably.

In another embodiment of the present invention, a chip type LED has a light emitting portion on a side surface. It is of a side view type, and at least a part of the side wall of the socket has an opening for passing light from the light emitting portion of the LED. This makes it possible to use side-view type LEDs.

According to yet another embodiment of the present invention, the plurality of light sources includes a light source having leads, and the connecting conductor structure has holes corresponding to the leads of the light sources. Preferably, the portion defining the hole of the connecting conductor structure includes a protrusion protruding toward the inside of the hole. Typically, the lead wire of the light source is inserted into a hole in the connecting conductor structure, thereby making an electrical-mechanical connection between the light source and the connecting conductor structure. Further, it is more preferable that the lead wire of the light source be caulked by the portion of the connection conductor structure close to the hole of the connection conductor structure, thereby holding the light source from the viewpoint of preventing undesired light source from falling off. Instead of directly inserting the lead wire of the light source into the hole of the connection conductor structure, the pin portion of the socket pin may be inserted into the hole of the connection conductor structure, and the lead wire may be inserted into the socket portion of the socket pin. According to yet another embodiment of the present invention, each of the plurality of light sources includes a pair of leads extending substantially parallel to each other, the plurality of light sources being arranged in a direction substantially orthogonal to the leads. The connecting conductor structure is arranged so that its main surface extends substantially along the leads, and is assembled to these leads to connect the light source. In such a case, the patterned conductor has a long tape shape and has a plurality of connection portions to the lead wires of the light source, and these connection portions correspond to the arrangement of the plurality of light sources held by radial taping. It is preferable that they are arranged side by side. According to this, when assembling the light source and the patterned conductor, the work can be performed in a state where a plurality of light sources are integrally held by radial taping, so that workability can be improved. After attaching the light source to the patterned conductor, place the leads In addition to cutting at a fixed location, a required portion of the patterned conductor is cut off to form a connection conductor structure, thereby obtaining a light source assembly. Further, it is preferable that the cross-sectional shape appearing when cut on a plane perpendicular to the longitudinal direction of the connection conductor structure is bent. As a result, even in a simple configuration in which the connection conductor structure is exposed without being covered with the insulating material, it is possible to prevent undesired contact between the connection conductor structure and the lead wire and to prevent an unintended short circuit in the circuit. Can be avoided. By exposing the connecting conductor structure without covering it with an insulating material, the heat dissipation effect of the connecting conductor structure is enhanced, and the advantage that the light source can be suitably accommodated even when the light sources are arranged at high density is obtained. Further, since the bending in the longitudinal direction is restricted, the workability when mounting to the holder can be improved.

The patterned conductor is preferably in the form of a long tape, and has a plurality of light source mounting portions arranged in a longitudinal direction for electrical connection with a light source; A communication path portion to be connected; at least one trunk path portion extending in the longitudinal direction separated from the connection path portion and the light source mounting portion in the width direction; And a branch portion. By doing so, it is possible to form a connection conductor structure capable of connecting the light source in various connection patterns by cutting off a predetermined portion of the branch, the communication, or the trunk. Further, in the light source connected body having the connection conductor structure formed in this way, the trunk path can be used to connect the light source to the power source, and in that case, it is not necessary to provide a separate wiring. Benefits are also obtained. When a part of the trunk of the patterned conductor is cut off so that the connecting conductor structure connects the light sources in series, the uncut part of the trunk corresponds to the corresponding branch through the corresponding branch. If it is left connected to the light source mounting part, the unremoved part of the trunk will act as a heat radiating part to dissipate the heat generated from the light source. Excessive rise in ambient temperature of the source can be prevented.

In the light source connected body formed using such a patterned conductor, a resistor is connected between at least a pair of adjacent light sources, and a communication path portion is formed between a pair of adjacent light sources connected between the resistors. It can be as if it were fragmented. This makes it possible, for example, to connect a resistor to the light source to prevent overvoltage from being applied to the light source. <More preferably, the light source connector extends in the width direction of the connection conductor structure. And a connecting member for integrally holding the communication path and the trunk road. In this manner, when a required portion of the patterned conductor is cut off to form the connection conductor structure, each part of the connection conductor structure can be prevented from falling apart, and the formed connection conductor structure can be prevented. Mechanical strength can be increased. Such a connecting member can preferably be formed by an insert mold. When the connecting member is formed by an insert mold, a widthwise recess or a through hole is provided in the trunk road portion, and if the connecting member extends through the widthwise recess or the through hole, the connecting member and This is preferable because the engagement with the main road can be strengthened. Further, it is preferable that a hole exposing the communication path is provided at a position where the connection path is aligned with the communication path of the connecting member, and the exposed communication path can be divided through the hole. By doing so, it is possible to form a connection conductor structure having a desired light source connection pattern by dividing the communication path after forming the connection member. The portion of the communication path exposed by the hole of the connecting member may have a smaller width than other parts of the communication path to facilitate resection. Further, the connecting member may include one or a plurality of insulating sheets. Regarding the insulating sheet, a plurality of insulating sheets may extend in the width direction of the connecting conductor structure at a predetermined place, or may be a single insulating sheet extending over substantially the entire length of the connecting conductor structure. Good. Such an insulating sheet By using the light source, it is possible to reduce the size (thickness) of the light source connected body manufactured as compared with the case where the connecting member is formed by the insert mold. When the insulating sheet is attached to the light source mounting surface of the connection conductor structure, the part to which the power supply voltage is applied is not exposed to the light source mounting surface that is relatively easy for workers to touch, improving safety. In addition, the insulating sheet reflects the light from the light source to increase the lighting efficiency.If the light source connected body does not have the connecting member by the insert mold or the light source is connected to the connecting conductor structure When such a connecting member is removed, for example, after installation, the branch road connecting the trunk road and the communication road is bent so that the main surface of the trunk road is substantially perpendicular to the main surface of the communication road. You may. By doing so, the light source connector can be easily attached to the holder by inserting the trunk road into the matching recess or hole formed in the holder.

Instead of, or in addition to, using a connecting member, a socket for mounting the chip-type LED extends in the width direction of the connecting conductor structure so that the communication path and the main path are integrally held. Can also.

When a plurality of light sources include a chip-type LED, the light source mounting part corresponding to the chip-type LED has a terminal connection part corresponding to a terminal of the chip-type LED, and at least one of these terminal connection parts has an extension part. However, the extension may be bent to form a wall for positioning or holding the chip type LED. Preferably, the terminal connection portion of the light source attachment portion corresponding to the chip type LED has a pair of extension portions facing each other. By doing so, the socket formed by insert molding or the like can be omitted.

It is not necessary to attach the light source to all the light source attachment portions, and the light source may not be attached to at least one of the light source attachment portions. By doing so, the spacing between the light sources can be flexibly changed. For example, when the light sources are connected in series or in series / parallel, the terminal connection portions included in each light source mounting portion are connected at the time of forming the patterned conductor (that is, at the time of primary processing), and the This can be achieved by separating the terminal connection part only at the light source mounting part where the light source is mounted during the secondary processing.

When at least one of the plurality of light sources includes a light source having a pair of terminals, the pair of terminals of the light source may be arranged in the width direction of the light source assembly. In this case, when the light source connector is flexed in the longitudinal direction, a force that separates the terminal of the light source from the connection conductor structure does not work. Can be prevented. Preferably, the light source mounting portion to which the light source having the pair of terminals is mounted has a pair of terminal connection portions corresponding to the pair of terminals, and the pair of terminal connection portions are arranged in the width direction of the patterned conductor. This is realized by being arranged. Further, when each light source has a pair of terminals, the patterned conductor preferably has a pattern that can be used for connecting the light sources in series, in parallel, or in series / parallel. By doing so, even if the light sources are connected in series, in parallel, or in series / parallel, the light sources can be formed from the same patterned conductor, thereby improving production efficiency and reducing production costs. Can be. According to a preferred embodiment of the present invention, the patterned conductor has an elongated tape shape and a plurality of light source mounting portions arranged in a longitudinal direction for electrical connection with the light source; Connecting section in the longitudinal direction, a pair of trunk sections disposed on both sides of the connecting section and the light source mounting section in the width direction, and extending in the longitudinal direction; the trunk section and the connecting path And a plurality of branch portions connecting the portions in the width direction. With such a structure, a common putter can be cut off by cutting off the required branch road, connecting road, or trunk road. Since a connection conductor structure having various light source connection patterns can be easily and efficiently manufactured from a single conductor on a single production line, the production cost can be kept low even in a small-scale production. Preferably, each of the light source mounting portions has a pair of terminal connection portions corresponding to a pair of terminals of the light source, and the communication path portion connects the terminal connection portions included in the adjacent light source mounting portions to each other. Including a plurality of connection paths.

When the plurality of light sources include two different color LED chips and a three-pole LED lamp having three terminals, the patterned conductor has a long tape shape, and is electrically connected to the light source. A plurality of light source mounting portions arranged in the longitudinal direction for connecting the light source mounting portion, a communication path portion connecting the light source mounting portion in the longitudinal direction, and a length disposed on both sides of the communication path portion and the light source mounting portion in the width direction. It has a pair of trunk roads extending in the hand direction, and a plurality of branch roads that connect the trunk road and the connecting road in the width direction, and each of the light source mounting parts has three terminals of a three-pole LED lamp. Has three terminal connection portions arranged in the width direction corresponding to each other, and the connection path portion includes a plurality of connection paths connecting the terminal connection portions aligned in the width direction of the adjacent light source mounting portions to each other. It is good to do so. By doing so, it is possible to realize a light source connected body using a three-pole LED lamp as a light source, and it is possible to variously change the emission color by connecting an appropriate power supply and switch.

The plurality of light sources include a four-pole LED lamp including first and second LED chips of different colors and having four terminals, wherein two of the four terminals are connected to the first LED chip. Connected, the other two being connected to the second LED chip, the patterned conductor has a long tape shape, and is disposed in a longitudinal direction for electrical connection with the light source. A plurality of light source mounting parts, a communication path part connecting the light source mounting parts in the longitudinal direction, and a longitudinal direction in which the communication path part and the light source mounting part are disposed on both sides of the width direction. And a plurality of branches connecting the main road and the connecting road in the width direction. Each of the light source mounting portions has four terminals of a 4-pole LED lamp. And four of the four terminal connections corresponding to the terminals connected to the first LED chip are arranged in the longitudinal direction of the patterned conductor, The two corresponding to the terminals connected to the second LED chip are aligned in the longitudinal direction of the patterned conductor, are separated from the other two terminal connection portions in the width direction of the patterned conductor, and the connection path portion is A plurality of connection paths for connecting the terminal connection portions aligned in the width direction included in the adjacent light source attachment portions, and the plurality of connection paths aligned in the longitudinal direction are branches extending in the width direction. Parts, and the patterned conductors are first and second A third trunk road extending in the longitudinal direction outward of any one of the trunk roads in the width direction, and a third trunk road and any one of the first and second trunk roads extending in the width direction. And a branch that communicates in the direction. As a result, a light source combination using a four-pole LED lamp as a light source can be realized, and the emission color can be variously changed by connecting an appropriate power supply and switch.

Preferably, the buttered conductor consists essentially of aluminum. It is preferable to attach the light source to the connection conductor structure by laser welding because the attachment can be easily performed with high reliability. Further, a resistor constituting a predetermined circuit together with the light source can be attached to the connection conductor structure by laser welding. The light source thus attached to the connection conductor structure by laser welding is typically a chip type LED (surface mount type LED), and such a resistor is a chip type resistor (surface mount type resistor). The present invention is not limited to this, and can be used for a light source having a lead wire as a terminal for electrical connection.

A light-emitting device base including at least one of the plurality of light sources; It may be an assembly. It is also advantageous if the patterned conductor has a projection that determines the position of the light source.

In still another preferred embodiment of the light source connecting body according to the present invention, the patterned conductor includes a pair of trunks extending substantially parallel to the longitudinal direction, and a plurality of branches connecting the pair of trunks to each other. A light source is connected between the pair of trunk roads, and the cut portion of the patterned conductor includes a branch. This embodiment is particularly suitable for implementing a light source assembly in which a plurality of light sources are connected in parallel between a pair of trunk roads. Since the pair of trunk roads is connected by a plurality of branch roads, handling of the patterned conductor is extremely easy, and the production efficiency can be improved. In addition, if the gap between the pair of trunk roads is non-linear (for example, bent in a square wave shape), the light source (LED) mounted between the pair of trunk roads is attached only in the longitudinal direction. It can be easily adjusted not only in the width direction but also in the width direction, for example, when the light source assembly is used to form an in-vehicle lamp, and when a different LED arrangement pattern is required depending on the vehicle type, Great economic benefits can be achieved by sharing parts.

When each of the plurality of light sources is composed of a plate-shaped LED having a cathode terminal and an anode terminal, the portion of the patterned conductor to which the power source terminal of each LED is attached has a larger area than the portion to which the anode terminal of the LED is attached. Good to do. This is because, in such an LED, the LED chip, which is usually sealed in a package, is mounted on the cathode terminal and connected to the anode terminal by a thin lead wire, etc. Most of the heat generated from the LED is radiated through the cathode terminal because the portion of the patterned conductor to which the cathode terminal of each LED is attached has a larger area, and is thus radiated from the power source terminal of the LED Heat can be dissipated more effectively. Patterned conductor is longitudinal When each LED is connected between a pair of trunk roads, the width of the trunk road to which the cathode terminal of the LED is attached is determined by the anode terminal of the LED. It should be larger than the width of the trunk road to be attached.

According to another aspect of the present invention, there is provided a light-emitting device including a light source connector that electrically connects a plurality of light sources and a holder that holds the light source connector, wherein the light source connector includes a plurality of light sources. It includes a connecting conductor structure extending in the arrangement direction of the light sources to connect the light sources, and the connecting conductor structure is formed by cutting out a required portion of a generally flat patterned conductor having a predetermined pattern formed thereon. The patterned conductor has a long tape shape, and has a plurality of light source mounting portions arranged in a longitudinal direction for electrical connection with a light source; A pair of trunk roads which are disposed on both sides of the communication passage and the light source mounting portion in the width direction and extend in the longitudinal direction, and the trunk road and the communication passage are arranged in the width direction. With multiple branches to contact In the connection conductor structure, the branch section connecting the trunk section and the communication path section is bent so that the main surface of the trunk section is substantially orthogonal to the main surface of the connection path section. The light emitting device is characterized in that the light source device is attached to the holder by inserting the light source into the corresponding hole or recess provided in the holder. In such a light emitting device, the light source connector can be attached to the holder simply by inserting the trunk road into the recess or hole of the holder, so that the efficiency of the attaching operation is improved.

According to another embodiment, a plurality of light sources each including a lead wire are electrically connected to each other in a direction substantially perpendicular to the lead wire, and a holding body that holds the light source connected body includes: Having a plurality of light sources connected by a connection conductor structure extending in the arrangement direction. By holding one or both of the lead wire and the connecting conductor structure to the holder side and inserting them into corresponding holes or recesses provided in the holder, the light source connector is held. A light-emitting device characterized by being attached to a body is provided. According to such a light-emitting device, a hole or a concave portion may be provided in the holder, and complicated processing is not required, so that various types of light sources having different positions can be easily manufactured. However, it is possible to reduce the cost in the case of producing a large number of products in small quantities. Furthermore, the light source connected body can be securely fixed to the holder with a simple configuration. In addition, the connecting conductor structure is arranged between the holder and the light source main body, and the light source main body is held in a state separated from the surface of the holder, so that the heat dissipation can be improved.

According to still another aspect of the present invention, there is provided a tape-shaped patterned conductor having a predetermined pattern for electrically connecting a plurality of light sources to form a light source connected body, the tape-shaped patterned conductor being electrically connected to the light source. A plurality of light source mounting portions arranged in the longitudinal direction for connection, a communication path portion connecting these light source mounting portions in the longitudinal direction, and a longitudinal direction separated from the communication path portion and the light source mounting portion in the width direction. There is provided a tape-shaped patterned conductor having at least one trunk road portion extending in the direction, and a plurality of branch road portions that connect the trunk road portion and the connecting road portion in the width direction. By using such a tape-shaped patterned conductor, it is possible to efficiently produce a light source assembly without using a printed circuit board. Further, by cutting off a part of the branch and / or the communication path as required, a light source connected body in which light sources are connected in various connection patterns can be easily formed.

Cutting (secondary processing) of such a patterned conductor can be efficiently performed at low cost by performing press processing using a progressive press machine. Therefore, it is engaged with the pilot pin of the progressive press machine on the trunk road and positioned. It is preferable that a plurality of holes (pilot holes) that can be used for carrying the patterned conductors be formed at predetermined intervals in the longitudinal direction. When each of the light sources has a pair of terminals for electrical connection, it is assumed that each of the light source mounting portions has a pair of terminal connection portions connected to a pair of terminals of the corresponding light source. Good. In this case, the communication path section may include a plurality of connection paths that connect the terminal connection sections included in the adjacent light source mounting sections. A hole for inserting a lead wire of an electric element having a lead wire such as a resistor may be provided in at least one of the connection paths or Z and the trunk road. If the pair of terminal connection parts of each light source mounting part are separated from each other, there are few places to cut out during the secondary processing of the patterned conductor, while if they are connected to each other, as necessary The portion connecting the terminal connections can be cut off, improving flexibility. A resistance mounting portion may be provided between at least one pair of adjacent light source mounting portions. Also, at least one of the branch portions may be replaced by a resistor mounting portion. By doing so, the resistor can be easily incorporated into the circuit. Further, the main road may have a convex curved portion in the width direction. By bending such a convex curved portion at the root portion, it can be used for connection with a holder or the like. When unwinding a coiled tape-shaped patterned conductor using a progressive press machine and assembling with multiple light sources held by radial tubing, a tape-shaped patterned conductor is used. In some cases, the trunk road may interfere with the main body of the light source.In such a case, if a convex curved portion is formed in the trunk road that interferes with the main body of the light source, the tape-shaped patterned conductor may be damaged. By bending the convex curved portion of the unwound portion, it is possible to prevent the trunk portion of the tape-shaped patterned conductor from interfering with the main body of the light source.

More preferably, the pair of trunk roads extends the light source mounting part and the communication path in a width direction. It is provided on both sides across the direction. In such a structure, it is possible to form a light source connected body that connects the light sources in any of a series-parallel, a parallel, and a series by cutting off a predetermined portion of the branch path and the Z or the communication path. That is, since light source couplings having various connection patterns can be produced from the same patterned conductor on the same production line, it is extremely useful in improving production efficiency and lowering production costs.

According to another embodiment of the present invention, there is provided a tape-shaped patterned conductor having a predetermined pattern for electrically connecting a plurality of light sources to form a light source assembly, comprising: The conductor is cut off at a required portion by a progressive press to form a connecting conductor structure that connects the light sources.The patterned conductor has multiple holes used for transport or positioning by the progressive press in the longitudinal direction. A tape-shaped patterned conductor characterized by being formed at a predetermined interval is provided. According to yet another embodiment, a plurality of light sources having leads are arranged in a direction substantially perpendicular to the leads, and are electrically connected to form a predetermined light source for forming a light source assembly. A plurality of connecting portions arranged in a longitudinal direction for connecting to a plurality of light source lead wires, and a communication path portion connecting these connecting portions in a longitudinal direction. A patterned conductor is provided, wherein a plurality of holes used for transport or positioning by a progressive press are formed at predetermined intervals in a longitudinal direction in a communication path portion. Thus, by providing a plurality of holes in the tape-shaped patterned conductor used for transport or positioning by the progressive press machine, handling of the patterned conductor by the progressive press machine is facilitated, and a light source using the same is provided. The production efficiency of the linked body can be improved. According to still another aspect of the present invention, there is provided a method for manufacturing a light source assembly having a plurality of light sources and a connection conductor structure for electrically connecting the plurality of light sources, comprising: Almost flat patterning with patterns Forming a conductor, assembling the patterned conductor with a light source, and cutting a required portion of the patterned conductor to form a connection conductor structure. Is provided. By doing so, it is possible to form a light source connected body including a connection conductor structure having various light source connection patterns by changing the cutout location of the patterned conductor. In addition, such a method eliminates the need for a printed circuit board and the solder normally used for connection with the printed circuit board.

Preferably, the step of forming the tape-shaped patterned conductor includes a step of pressing a conductive flat material. Further, it is more preferable in terms of working efficiency if the step of cutting off a required portion of the patterned conductor and the step of assembling the Z or patterned conductor to the light source are performed by a progressive press. The method further includes attaching a connecting member to the tape-shaped patterned conductor so as to integrally hold each part of the connection conductor structure formed from the patterned conductor. When the connection conductor structure is formed after the mounting process, the individual portions of the formed connection conductor structure can be prevented from falling apart. In that case, it is preferable that at least one hole is provided in the connecting member to expose a required portion of the patterned conductor. Thereby, the portion of the patterned conductor exposed by the hole can be cut off as needed. If the light source includes a chip-type LED and the method includes attaching a socket for mounting the chip-type LED to the patterned conductor, the step of cutting off a required portion of the patterned conductor is performed after the socket attaching process. It may be done.

When the light source includes a light source having a lead wire, assembling the patterned conductor to the light source may include inserting a lead wire of the light source into a corresponding hole provided in the connection conductor structure. . Alternatively, the process of cutting the patterned conductor may be performed after the process of assembling the patterned conductor to the light source. According to this, each part of the connection conductor structure formed by cutting off a required portion of the patterned conductor can be prevented from being separated without using a connecting member. Also, if each of the light sources has a pair of leads for electrical connection, the use of solder is eliminated if the assembling step includes a step of caulking the leads at predetermined portions of the patterned conductor. This is preferable because it can be performed. Such a joining method by staking is also suitable from the point that it is suitable for performing by a progressive press.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front sectional view showing a preferred embodiment of a light emitting device according to the present invention. As shown, the light emitting device includes a plurality of light emitting diodes (LEDs) 1 as light sources, each LED 1 having two parallel leads 3 as terminals for electrical connection. The package part (body part) 1a is a so-called shell-type LED (or lamp-type LED) with a gun-shaped configuration. These light sources 1 are arranged side by side in a direction orthogonal to the lead wire 3 on the surface of a mounting port (holding body) 2. The plurality of light sources 1 are connected in series by the connecting conductor structure 4 extending in the arrangement direction. Are connected in series to form a light source connector 6. Such a series-parallel structure not only allows connection to a commercial power supply without using a step-down transformer, etc., by appropriately setting the number of light sources connected in series, but also enables such a light source series body (series block) to be connected. There is an advantage that any number of light sources can be used by connecting a plurality of parallel connections. As shown in the figure, the connection conductor structure 4 is connected to the lead wire 3 of the predetermined light source 1. And a plurality of connecting pieces 5 for connecting the lead wires 3 of the adjacent light source 1 with first and second trunk paths 11 and 12 extending in the longitudinal direction to which the power supply voltage is applied. are doing. Each connecting piece 5 has a pair of connecting portions 9 at both ends, and is connected to the base 3 a of the lead wire 3 of the adjacent light source 1 via the pair of connecting portions 9. The first and second trunk roads 11 1 and 12 are connected to the base 3 a of the lead wire 3 of the associated light source 1 via the branch roads 13 and 14 and the connection 9 connected thereto, respectively. Are combined. Further, a slit 15 extending in the width direction is provided in the first main road section 11 on the main body section 1a side of the light source 1, and the main road section 11 is meandering. Alternatively, it can be said that a portion corresponding to the mounting position of the light source and the longitudinal direction is convexly curved. In order to fix the light source connector 6 formed in this way to the mounting port 2, the tip 3b of the lead wire 3 is inserted into the mounting hole 7 formed in the mounting port 2.

FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1, and FIG. 3 is a perspective view showing the light source assembly 6 shown in FIG. In FIG. 3, the main body 1a of the light source 1 is shown by a broken line for easy viewing. In the same figure, the tape-shaped patterned conductor 16 which is the basis of the connection conductor structure 4 described in detail later is also indicated by a broken line.

As is well shown in FIG. 3, in this embodiment, each connecting portion 9 has a plate-like portion, and the plate-like portion is folded so as to sandwich the corresponding lead wire 3. It is fixed to the lead wire 3 by bending and caulking. In addition, the connecting portion 9 can take various forms other than caulking, such as engagement by an elastic engagement piece and spot welding.In the case of caulking, it can be processed continuously by a progressive press. This has the advantage that the use of solder can be eliminated and there is no fear that the light source (LED) 1 will be adversely affected by heat.

As is well shown in FIGS. 2 and 3, the connecting conductor structure 4 has a position substantially corresponding to the bottom of the cut 15 of the first trunk section 11 and the branch section 14 and the connecting piece 5. Are bent along a bending line extending in the longitudinal direction at a position substantially corresponding to the boundary of the arrow. Thereby, the first and second trunk roads 11 1 and 12 form a predetermined angle in the cross section of FIG. 2 with respect to the connection 9 along the lead wire 3. By bending the cross-sectional shape in the width direction of the connecting conductor structure 4 (that is, the cross-sectional shape that appears when cut along a plane perpendicular to the longitudinal direction) in this manner, the light source body 1a and the first trunk path are bent. Not only can it prevent interference with part 1 1, but also the first and second trunk sections 1 1, 1 2 can be directly connected to the lead 3 of the light source 1 even in a simple configuration without insulation treatment on the connection conductor structure 4. Unintended short circuit in the circuit due to contact can be avoided. By leaving the connecting conductor structure 4 exposed without covering it with an insulating material, the heat dissipation effect of the connecting conductor structure 4 is enhanced, and it is possible to suitably cope with the case where the light sources 1 are densely arranged. Benefits are also obtained. In addition, since the bending in the longitudinal direction is restricted, the workability when mounting to the mounting pod 2 can be improved. Further, the tip 3b of the lead wire 3 projects toward the mounting board 2, so that the mounting pod 2 can be inserted into the mounting hole 7.

According to the present invention, the connection conductor structure 4 as described above is preferably a tape in which a circuit pattern that can be used in series, parallel, and series / parallel is formed in advance by pressing (piercing) a conductive flat plate material. When the patterned conductor 16 is assembled with the light source 1, can get. As will be described in detail later, the light source 1 can be connected in series, in parallel, or in series-parallel by changing the cut portion of the tape-shaped patterned conductor 16.

FIG. 4A is a front view showing one embodiment of the tape-shaped patterned conductor 16 before the secondary processing. In the figure, the same reference numerals are given to portions corresponding to the above-described connection conductor structure. In FIG. 4 a, the plurality of connection portions 9 connected to the lead wire 3 of the light source 1 are shown before being bent to be connected to the lead wire 3. These connecting parts 9 are connected by a connecting path part 10 extending in the longitudinal direction. The first and second connecting parts 9 and the connecting part 9 are sandwiched in the width direction (vertical direction in the figure). The trunk sections 11 and 12 are arranged on both sides of the tape-shaped patterned conductor 16. The first and second trunk roads 11 and 12 and the communication road 10 are connected in the width direction by a plurality of branch roads 13 and 14.

As described above, the tape-shaped patterned conductor 16 is subjected to the secondary processing of cutting out a required portion according to the use as described above, thereby forming a connection conductor structure 4 having a circuit of a predetermined connection pattern. It is preferable that the subsequent processing be performed at the same time when the light source 1 held by radial taping and the tape-shaped patterned conductor 16 are assembled by a progressive press machine, because the manufacturing process can be simplified. For this reason, in the tape-shaped patterned conductor 16 shown in Fig. 4a, the light source 1 and the tape-shaped patterned conductor 16 are aligned so that the light source 1 can be properly assembled at a predetermined position of the tape-shaped patterned conductor 16. For positioning, a pilot hole 18 for engaging with a pilot pin of a progressive press (not shown) is provided in the second main path section 12 on the side opposite to the light source body section 1a. . As another method, as shown in a tape-shaped patterned conductor 16 ′ shown in FIG. 4B, a cross section 19 connected to the second main road section 12 via a connecting section 20 is provided. Pilot hole 18 to be engaged with pilot pin of progressive press machine Although it may be made, more material is required for the edge 19 than in the case of Fig. 4a.

The tape-shaped patterned conductor 16 can be obtained by pressing (more specifically, punching) a conductive flat plate material. Specifically, first, the connecting portion 9 is formed so as to protrude from the connecting portion 10 in the direction along the lead wire 3, and the connecting portion 10 and the first trunk portion 11 are defined. A cutout hole 21 defining a branch 13 connecting them is formed. The cutout hole 21 secures a space into which the tool for caulking the connection portion 9 is inserted. A cut 15 is formed in the first trunk road 11. Further, a cutout hole 22 that defines the connection path portion 10 and the second main road portion 12 and defines a branch path portion 14 that connects them is formed. The branch sections 13 and 14 connecting the first and second trunk sections 11 and 12 and the communication section 10 are displaced from the lead 3 so as not to cut the lead 3 when cutting. It is preferable to form it at the position. As a result, the lead wire 3 is made to protrude, for example, toward the mounting port 2 having an appropriate length, and inserted into the mounting hole 7 provided in the mounting port 2 when the completed light source connector 6 is mounted on the mounting board 2. To stabilize the mounting (see Fig. 1).

Since the tape-shaped patterned conductor 16 is flexible and bendable, it can be wound into a coil or folded in a zigzag manner, and can be easily stored, transported, and packed.

FIG. 5 shows a situation in a manufacturing process of the light emitting device shown in FIG. The light source 1 is a gun-shaped LED lamp in which a pair of lead wires 3 are drawn in the same direction, and is arranged side by side in a direction perpendicular to the lead wires 3 by radial taping. The carrier tape 25 for radial taping consists of a pair of tapes 25a and 25b that are attached to each other. Is made. The carrier tape 25 is provided with pilot holes 26 in the same manner as the tape-shaped patterned conductor 16, and the tape-shaped patterned conductor 16 and the pilot holes 18, 2 of the carrier tape 25 are provided. By aligning 6, the connection portion 9 formed on the tape-shaped patterned conductor 16 and the lead wire 3 of the light source 1 held by the carrier tape 25 are aligned in the axial direction. In this way, the connection portion 9 is engaged with the lead wire 3 held in the tape 25, and the tape-shaped patterned conductor 16 is subjected to the secondary processing. When the lead wire 3 and the connecting portion 9 are engaged with each other, the main body 1 a of the light source 1 and the first trunk 11 of the tape-shaped patterned conductor 16 do not interfere with each other. It is necessary to bend the loop-shaped patterned conductor 16 along the longitudinal bending line.

The connection between the tape-shaped patterned conductor 16 and the light source 1 as described above is performed while preparing a coil-shaped tape-shaped patterned conductor 16 and unwinding it in a progressive press machine. This is preferable in terms of work efficiency and ease of handling. In the tape-shaped patterned conductor 16 according to the present invention, as described above, the notch 15 in the width direction is formed in the first trunk road portion 11, and the first trunk road portion 11 has a plurality of convex portions. Even if it is wound in a coil shape, only the convex curved portion of the part that is unwound to engage with the lead wire 3 of the light source 1 is individually bent because it has a curved shape. Accordingly, it is possible to prevent the main body 1a of the light source 1 from interfering with the first trunk road 11 of the tape-shaped patterned conductor 16.

FIG. 6 is a view showing a procedure of secondary processing of the tape-shaped patterned conductor 16 for making the serial-parallel light emitting device shown in FIG. In this figure, the resected part is shown with diagonal lines. As shown, a portion 27 of the communication path portion 10 between a pair of connection portions 9 to which the lead wires 3 of the same light source 1 are connected is cut off. The range in which light source 1 is connected in series (series block The remaining branches 13 and 14 except for the branches 13 and 14 located at the end of (h) are cut off, and the connection 10 that connects the adjacent series blocks 2 8 is resected. In this way, it will be understood that, for example, the connecting piece 5 of the connecting conductor structure 4 shown in FIG. 1 is formed from the communication path 10 of the tape-shaped patterned conductor 16. As described above, in the secondary processing, the tape-shaped patterned conductor 16 (or the connection conductor structure 4) is bent along the longitudinal bending lines on both sides of the communication path 10, and preferably, the connection 9 Is fixed to the lead wire 3 by swaging. A notch along the bending line may be formed in advance on the tape-shaped patterned conductor 16 so as to facilitate bending. Further, the tape-shaped patterned conductor 16 is preferably cut at an appropriate location so that the formed light source connector 6 has an appropriate length that is easy to handle. The secondary processing of the tape-shaped patterned conductor 16 which can include such processing steps as cutting, bending, caulking, and cutting can be performed by a progressive press machine. The bending of the tape-shaped patterned conductor 16 on the side of the second main path section 12 provided with the pilot hole 18 for engaging with the pilot pin of the progressive press machine may be performed in the final step. Alternatively, it may be performed after taking out the completed light source assembly 6 from the progressive press.

The part 27 of the connecting part 10 between the connecting part 9 to the lead wire 3 of the same light source 1 must be separated in any connection form, and this part 27 is processed at the stage of processing the tape-shaped patterned conductor 16. However, leaving this portion 27 has an advantage of stabilizing the connection portion 9 in the step of fixing the connection portion 9 to the lead wire 3.

FIG. 7 is a view showing a procedure of secondary processing of the tape-shaped patterned conductor 16 to form a parallel-type light emitting device. The cut portion is shown with diagonal lines in the same manner as described above. In addition to cutting off the portion 27 of the connecting portion 10, the portion 29 of the connecting portion 10 connecting the connecting portion 9 to the lead wire 3 of the adjacent light source 1 is cut off. Similarly to the above, the connection path 10 is bent along the bending lines in the longitudinal direction on both sides, and the connection section 9 is fixed to the lead wire 3 by caulking. In this connection mode, the branch portions 13 and 14 are left without being cut off. FIG. 8 is a view showing a procedure of secondary processing of the tape-shaped patterned conductor 16 to form a serial light emitting device. Similarly to the above, the cut portion is shown with diagonal lines, and in addition to cutting off the portion 27 of the communication path portion 10 between the pair of connection portions 9 for the lead wire 3 of the same light source 1, a pair of stems The roads 11 and 12 and the branches 13 and 14 are all cut off, leaving connection pieces 5 separate from each other. Each connecting piece 5 has a form in which a pair of connecting parts 9 protrude from both ends of the main body extending in a direction orthogonal to the lead wire 3 in a direction along the lead wire 3. The one lead wire 3 is electrically connected to the adjacent lead wire 3 of the light source 1 and connected to each other to obtain a light source connected body. As described above, in the present embodiment, the connection conductor structure 4 that connects the light sources 1 only by the connection pieces 5 is formed.

FIG. 9 is a cross-sectional view showing a light emitting device in which a series light source connector 32 obtained by the secondary processing shown in FIG. 8 is mounted on a mounting board (holder) 2. Here, the connection pieces 5 are not joined to the lead wires 3 at both ends, and the lead wires 3 except for both ends are cut off at the same time when the connection pieces 5 are separated, and do not protrude to the mounting board 2 side. . Lead wires 3 at both ends are cut to a required length, inserted into mounting holes 33 formed in mounting board 2, and connected to wiring for applying a power supply voltage.

FIG. 10 is a diagram showing another embodiment of the secondary processing of the tape-shaped patterned conductor 16 to form a serial light emitting device. The cut portion is shown with diagonal lines in the same manner as above, and the portion of the communication path portion 10 between the lead wires 3 of the same light source 1 is shown. In addition to cutting off part 27, here all other parts are cut off except that the branch 13 connected to the first trunk 11 is located at the other end (right side in the figure). Is done. Also, the second trunk road section 12 is cut off together with the branch road section 14 except for a portion connected to the connection section 9 located at the other end (left side in the figure). In this example, unlike the above example, since the first and second trunk roads 11 and 12 remain, the power supply voltage can be applied thereto.

FIG. 11a is a cross-sectional view showing an example of a different attachment form of the light source connector to the holder. The connecting piece 35 of the light source connector 37 in this embodiment has projecting portions facing the mounting port 2 at both ends thereof, and the end of the lead wire 3 is also aligned therewith. The end of the lead wire 3 and the projecting portion of the connection piece 35 are both inserted into the mounting hole 36 formed in the mounting board 2, so that the light source connector 37 is supported on the mounting board 2. Has been made. Such a connecting piece 35 extends the branch portion 14 of the tape-shaped patterned conductor 16 shown in FIG. 4a not only to one of the pair of connecting portions 9 associated with each light source 1, but also to both of them. In the secondary processing of such a tape-shaped patterned conductor, the branch portion 14 together with the lead wire 3 of the light source 1 coupled to the tape-shaped patterned conductor is provided. It can be formed by cutting at the root of the second trunk road section 12 side. In addition, it is good also as a structure which protrudes every two or more and inserts it into the mounting hole 36.In this case, the number of the lead wires 3 inserted into the mounting hole 36 is such that the light source connector 37 is appropriately held on the mounting board 2. It is set in consideration of the rigidity of the lead wire 3 and the connection piece 35 so as to be set. Further, as shown in FIG. 11b, the mounting hole 36 may be a recess 36 ′ like a groove instead of the through hole. Such a concave portion 36 'may be formed integrally when the mounting port 2 is manufactured by molding, for example, or may be formed by cutting after the mounting board 2 is formed. Alternatively, it can be formed by providing a plurality of protrusions on the mounting port 2. FIGS. 12 and 13 are diagrams showing examples in which the light source 1 is arranged on a holder. FIG. 12 shows an example in which the plurality of light sources 1 are connected to the surface of a flat holding member (mounting board) 41 via the connection conductor structure 4. 2 forms a loop by appropriately bending the connection conductor structure 4, and is arranged so that the light source row by the light source connector 42 indicates the outline of the character. FIG. 13 shows an example in which the light sources 1 are arranged on a curved surface. It is wound. Note that a configuration in which light sources are densely arranged on the surface of the holder to form a surface light emitter is also possible.

FIG. 14 is a front view showing a modified embodiment of a patterned conductor suitable for forming a series connection of light sources, and FIG. 15 is a view of a secondary processing when assembling the patterned conductor with the light source 1. This is a diagram showing the outline (removed parts are indicated by oblique lines). In these figures, the same parts as those in FIG. 4A or FIG. 6 are denoted by the same reference numerals, and detailed description is omitted. As shown in the figure, the patterned conductor 16〃 for forming a series connection has a pilot hole 18 'for positioning or transport on the production line formed in the communication path section 10'. The first and second trunk roads 11 and 12 shown in FIG. 4 and branch roads 13 and 14 connecting these trunk roads 11 and 12 to the communication road 10 are provided. However, the width is narrowed accordingly. In this manner, unnecessary materials can be saved when the light source assembly is completed, and the cost can be significantly reduced.

In the above-described embodiment, an example in which the LED is used as a light source has been described. However, the present invention is not limited to this, and can be similarly applied to a baseless bulb having a lead wire.

As described above, according to the embodiment of the present invention, a tape-shaped patterned conductor in which a predetermined circuit pattern capable of commonly using various light source connected bodies having different light source connection patterns is formed in advance. From the same production line Therefore, the productivity can be improved and the manufacturing cost can be reduced, and a great effect can be obtained in reducing the manufacturing cost of the light emitting device using such a light source connector. Further, since the light source is integrated as a light source connected body and then fixed to the holder, various arrangements of the light source can be easily handled. Further, since the holder does not require complicated processing, it is possible to suppress an increase in manufacturing cost even when a large number of types are manufactured in small quantities.

In the above embodiment, the light source has a pair of generally parallel extending lead wires, and these lead wires extend substantially along the main surface of the connection conductor structure (the multi-turn conductor). However, there are also cases where it is desired to mount the light source so that the light source leads extend substantially perpendicular to the main surface of the connecting conductor structure, or where the light source is a so-called chip LED without leads. Conceivable. The following embodiments of the present invention are suitable for such a case.

FIG. 16 is a partial perspective view showing another preferred embodiment of the light source assembly according to the present invention. As shown, the light source assembly 101 uses a plurality of light emitting diodes (LEDs) 102 as light sources, and each LED 102 has two parallel leads as terminals for electrical connection. It is a so-called bullet-type LED (or lamp-type LED) with a line 103. The plurality of LEDs 102 are arranged in a direction orthogonal to the lead wires 103, and are electrically connected by a substantially flat connecting conductor structure 104 extending in the arrangement direction. In the illustrated example, the LEDs 102 are connected in series / parallel (that is, a plurality of LEDs 102 connected in series and further connected in parallel). Other connections such as series connection and parallel connection are also possible depending on the configuration of the conductor structure 104.

The connection conductor structure 104 has first and second trunk sections 1 1 1 and 1 1 2 extending in the longitudinal direction to which the power supply voltage is applied. A light source mounting portion 105 for connecting to the lead wire 103 of the second device 102 and a communication path 110 connecting the light source mounting portion 105 in the longitudinal direction are arranged. As can be seen from the figure, each light source mounting portion 105 has a pair of terminal connection portions 109 coupled to a pair of lead wires (terminals) 103 of one LED 102. In the example, the pair of terminal connection portions 109 are separated from each other in the longitudinal direction. The first and second trunk roads 1 1 1 and 1 1 2 are connected to the connecting road 1 1 10 at predetermined locations by branch roads 1 1 3 and 1 1 4 extending in the lateral direction (width direction). It is electrically connected, and in the example shown, forms a conductor pattern that connects the LEDs 102 in series and parallel. Further, the communication path section 110 and the first and second main path sections 111, 112 are preferably formed by an insulating connecting member 115 extending in the width direction formed by insert molding. They are mechanically connected and held together.

Each terminal connection portion 109 of the connection conductor structure 104 is preferably formed with a cross-shaped hole 1 16, and the hole 1 16 is provided with a lead wire 10 of the corresponding LED 102. By pushing in 3, a mechanical Z electrical connection between the connection conductor structure 104 and the LED 102 is made. Due to the cross shape of the hole 1 16, four protrusions are formed inward, and when the lead wire 103 is pushed in, these four protrusions bend and the lead wire 103 is bent. It works to hold tightly. As shown in Fig. 17a, which is a cross-sectional view along the line XV II -XV II in Fig. 16, after the lead wire 103 is inserted into the hole 1 16 The portion 1 17 extending in the width direction on both sides of the hole 1 16 is bent, and the lead wire 103 is undesirably holed by crimping so that the lead wire 103 is sandwiched. Exiting from 6 is more effectively prevented. After caulking the lead wire 103 with the extension part 117, the lead wire 103 is cut to an appropriate length. The lead wire 103 may be cut into a predetermined length in advance. Lead 10 as shown 3 can be used to attach the light source connector 101 to the holder 123 by inserting it into the corresponding recess or hole 124 provided in the mounting board (holder) 123.

The connection between the terminal connection part 109 and the lead wire 103 is made by inserting the lead wire 103 into the hole 116 and crimping the lead wire 103 by the extension part 117. , Spot welding, ultrasonic welding, laser welding, etc., but with the connection method described above, it is possible to continuously process by progressive press, eliminate the use of solder, LED by heat There is an advantage that there is no fear of adversely affecting 102. The insertion of the lead wire 103 into the hole 116 and laser welding may be used in combination. In this case, the hole 116 has an inward protrusion as shown in the figure, and when the lead wire 103 is pushed into the hole 116, the protrusion warps and is pressed against the lead wire 103. By doing so, the contact area is increased and laser welding can be performed more reliably. In addition, a notch is formed in a portion of the communication path portion 110 adjacent to the hole 1 16 of the terminal connection portion 109 to form a tongue piece, and the tongue piece is bent to form the pair of extension portions described above. The lead wire 103 may be swaged from three directions together with 1 17.

Further, as shown in the sectional view of FIG. 17b, a so-called “socket bin” 125 can be inserted into the hole 116 to be used for connection with the lead wire 103. A socket pin is a pin that includes a conductor (concave portion or female portion) formed on the back side of a pin portion (a convex portion or a female portion), and is, for example, sold by Mac Eight Co., Ltd. You can use the PD series, etc. By inserting the pin portion of the socket pin into the hole 1 16 in advance, inserting the lead wire 103 into the socket portion of the socket pin allows the electrical connection between the LED 102 and the connection conductor structure 104. Connection can be made easily. According to the present invention, the connection conductor structure 104 as described above preferably has a circuit pattern that can be used in series, in parallel, and in series in parallel, preferably by pressing (drilling) a conductive flat plate material. It can be obtained by subjecting the patterned conductor formed by processing to secondary processing for cutting out the required portions. By doing so, it is possible to connect the LEDs 102 in series, parallel, or series-parallel by changing the cutouts for the patterned conductor.

FIG. 18 is a partial plan view showing a preferred embodiment 120 of the patterned conductor before the secondary processing. In the figure, the portions corresponding to the connection conductor structure 104 described above are denoted by the same reference numerals. As shown in the figure, the patterned conductor 120 is in the form of a long tape having self-supporting properties (that is, each part is integrated), and the communication path 110 is formed in the longitudinal direction. It extends to connect the light source mounting part 105. In addition, the first and second trunk roads 1 1 1 and 1 1 2 are arranged on both sides of the patterned conductor 1 20 with the light source mounting section 1 05 and the communication path 1 1 10 sandwiched in the width direction. . In addition, each terminal connection section 109 of each light source mounting section 105 is connected to the first and second trunk sections 1 1 1 and 1 1 2 by the corresponding branch sections 1 1 3 and 1 1 4 respectively. I have. The communication path section 110 is connected to the lead wire 103 of the adjacent different LED 102 (that is, included in the adjacent light source mounting section 105). 9 includes a plurality of connection paths 1 2 1 respectively connecting the 9. The connecting member 115 formed by insert molding can be formed on this connecting path 121 (see FIG. 16). At this time, a hole 1 19 is provided at a position of the connecting member 1 15 which is aligned with the connection path 1 21 so as to expose the connection path 1 2 1 (the connection path 1 2 exposed by the hole 1 19). The portion 1 is referred to as a bridge portion 12 21 A (see FIGS. 19 to 21). Thus, after forming the connecting member 115, a punch (not shown) of the press machine is inserted through the hole 119 to form the bridge portion 112. By cutting off 1 A, it becomes possible to cut off the terminal connection section 109 connected via the connection path 121.

As described above, the patterned conductor 120 becomes a connection conductor structure 104 having a circuit of a predetermined connection pattern by performing secondary processing for cutting out a required portion according to the application as described above. The connection is preferably performed after connecting the trunk roads 111, 112 and the communication road 110 with a connecting member 115, preferably formed by an insert mold. By doing so, it is possible to prevent each part of the formed connection conductor structure 104 from being separated. The formation of the connecting member 115 and the secondary processing of the patterned conductor 120 by such an insert mold are efficient if performed on a continuous production line. Therefore, a pilot hole 1 18 for engaging with a pilot pin of, for example, a progressive press machine (not shown) is provided in the second main road section 112 for positioning of the transport Z in the production line. .

The patterned conductor 120 described above can be preferably obtained by pressing (more specifically, punching) a conductive plate material made of a metal such as aluminum or copper. Aluminum is not used for printed circuit boards because it is unsuitable for soldering, but it has the advantage of being low in specific gravity (about 1 Z3 of copper) and suitable for weight reduction of products. It is also preferable that the thermal conductivity is high (several times that of copper) and the conductivity is high. In addition, the printed conductor has a thickness of about 35 xm, while the patterned conductor can be made as thick as 100 to 3 OO m, which has the advantage that the allowable current value can be increased. It is also preferable from the viewpoint of. It is also possible to form the patterned conductor 120 by photo-etching the conductive plate material or cutting it by wire cutting, laser or electric discharge machining. It can also be formed by die casting such as magnesium molding. Since the patterned conductor 120 is flexible and bendable, the coil It can be rolled up or folded in a zigzag, making it easy to store, transport and pack.

FIG. 19 to FIG. 21 are diagrams showing the procedure of secondary processing of the patterned conductor 120 when the LEDs 102 are connected in series, parallel, and series, respectively. In these figures, the resected part is shown with diagonal lines. In addition, a connecting member 1 15 having a hole 1 19 is shown by a dotted line so that the position of the cut portion can be easily understood.

In the example of Fig. 19, there is a connection conductor structure that can connect a plurality of series-connected bodies (series blocks) each including three LEDs 102 in parallel between the trunk sections 1 1 1 and 1 1 2. Provided. More specifically, the bridge section 1 2 1 A of the connection path 1 2 1 located between the adjacent series blocks is disconnected, and the connection path 1 2 1 connecting the terminal connection sections 1 0 9 in the series block remains unchanged. Is done. The branch sections 113, 114 included in each series block include a branch section 113 connected to the first trunk section 111 at one end and a second branch section 113 at the other end. All of them are removed except for the branch 1 114 connected to the trunk 1 1 2. The number of LEDs 102 that can be included in each series block can be changed by changing the branch sections 113, 114 and the bridge section 121A to be cut, and is not limited to three. Please understand that there is no. Further, in the example of FIG. 19, adjacent LEDs 102 included in the same series block are connected to each other (that is, terminal connections included in adjacent light source mounting portions 105 are connected to each other). The bridge portion 121A is left uncut, but as shown by a dotted line in the perspective view of FIG. 16, for example, a resistor 122 is inserted between adjacent LEDs 102, for example, as a spot. When connecting to the communication path section 110 by welding, laser welding, or the like, the bridge section 121 A located between both terminals of the resistor 122 may be cut off. Similarly, as shown by the dotted line, connect the resistance 1 2 2 between the communication path 1 110 and the second main path 1 1 2 To do this, it is advisable to cut off the branch section 114 at the corresponding position.

The same applies to the connection between the road section 110 and the first trunk section 111. In the example of FIG. 20, all the bridge portions 121 A are cut off, and the branch portions 113, 114 are connected to each LED 102 (ie, in each light source mounting portion 105). One of the terminal connection portions 109 is cut off so as to be connected to the main road portion 111, and the other is connected to the main road portion 112. In this way, a connection conductor structure is provided in which a plurality of LEDs 102 attached to the light source mounting section 105 are connected in parallel between the trunk sections 1 1 1 and 1 1 2. .

In the example of Fig. 21, all branches 1 13 and 1 14 are cut off, while all bridges 1 2 1 A are left uncut and remain between trunks 1 1 1 and 1 1 2 In this way, a series body of LEDs 102 can be formed. It can be said that the connection piece for connecting the adjacent LEDs 102 is formed by the connection path 122 and the pair of terminal connection portions 109 connected by the connection path. In the light source connected body 101 which connects the LEDs 102 by the connection conductor structure formed in this way, the trunk roads 1 1 1 and 1 1 2 are not used, for example, at both ends of the LED series body. The power supply may be connected directly to the lead wire 103 of the LED 102 located, but the trunk roads 1 1 1 and 1 1 can be obtained by leaving appropriate branches 1 13 and 1 14 2 is connected to the LED series, and the trunks 1 1 1 and 1 1 2 are connected to the power supply, and the voltage from the power supply is supplied to the series D via the trunks 1 1 1 and 1 1 2. You can also make it. Only one of the trunk roads 111 and 112 may be used for connection to such a power source.

As described above, according to the preferred embodiment of the present invention, by changing the branch portions 113, 114, and the bridge portion 121A to be cut, various connection patterns can be formed from the common patterned conductor 120. It is understood that it is possible to form the connecting conductor structure 104 having the following (and the light source connecting body 101 having the same). Will be. The formation of the connection conductor structure 104 by the secondary processing of the patterned conductors 120 can be suitably performed by press working. At that time, when the connection conductor structure 104 of a different connection pattern is formed, The selection of the branch section 1 13, 1 1 4 and the bridge section 1 21 A to be cut off can be made by, for example, computer control, and there is no need to change the die of the press machine. Eliminating time loss and work mistakes associated with replacement, it has become possible to improve productivity and reduce manufacturing costs. In addition, since a printed circuit board is not used to form the light source connector 101, solder that is normally used for connection to the printed circuit board can be eliminated, which not only reduces adverse effects on the environment but also uses solder. The adverse effect of heat on the light source (LED) can be eliminated. In addition, since it has a very simple structure consisting of a light source (LED) and a connecting conductor structure, it is easy to disassemble and does not use a printed circuit board that is difficult to recycle. it can.

FIG. 22 is a partial perspective view showing another embodiment of the light source assembly according to the present invention. The light source connector 15 1 shown in FIG. 22 includes a pair of electrical connection terminals 15 3 extending from the side surface to the bottom surface in place of the lead wire 103, and a light emitting portion 15 5 on the upper surface. A normal type chip LED (or LED for surface mounting) 152 having 2 A is used as a light source. Such chip-type LEDs are extremely small, with a vertical, horizontal, and height dimension of several mm or less, and are commercially available.The dimensions of the light source assembly 151 manufactured using them are also reduced. .

As in the above-described embodiment, the LED 152 is electrically connected to a connection conductor structure 150 obtained by secondary processing of a generally flat conductor 170 (see FIG. 25). Connected. Similarly, the connection conductor structure 15 4 includes first and second trunk sections 16 1 and 1 1 extending in the longitudinal direction to which the power supply voltage is applied. In the meantime, there is a communication path section 160 that connects the light source mounting section 15 5 (see Fig. 25) for connection to the LED 155 in the longitudinal direction. Have been. The first and second trunk paths 161, 162 are electrically connected to the communication path section 160 at predetermined locations by branching sections 163, 164 extending in the width direction. In the example shown in the figure, a conductor pattern for connecting the LEDs 152 in series and parallel is configured. As in the embodiment of FIG. 16, the second trunk section 162 is provided with a pilot hole 168 for easy handling by a progressive press. In addition, the communication path section 160 and the first and second trunk paths 161, 162 are mechanically connected by a connecting member 1 65 extending in the width direction formed by insert molding. ing.

In this embodiment, a generally box-shaped socket 172 having an opening on the upper surface for mounting the chip-type LED 155 is positioned at a position aligned with the light source mounting portion 155 of the connection conductor structure 154. Is formed. Such a socket 172 can be preferably formed by an insert mold.

Fig. 23 is a top view showing the socket 1 72 (the second from the left in Fig. 22) without the LED 15 2 installed, and Fig. 24 shows the socket with the LED 152 installed. 3 is a side sectional view showing a socket 17 2 (for example, the left end in FIG. 22) of FIG. As shown in these figures, each light source mounting portion 155 of the connection conductor structure 154 has a pair of terminal connection portions 159 which are separated from each other in the longitudinal direction. Portion 159 is exposed on the bottom wall of socket 172, and when LED 153 is inserted into socket 172, terminals 153 and connection conductor of LED 155 are connected. The terminal connection portion 159 of the structure 154 is in contact with the structure. Also, small projections 1667 are provided on the surface of each terminal connection portion 159 so that the terminal 153 of the LED 155 and the terminal connection portion 159 are surely in contact with each other. In addition, a hole 1 73 was formed in the bottom wall of the socket 1 72, from which the socket 1 72 was mounted. The LED l52 can be removed from the socket 172 by pressing the LED l52. This allows the failed LED 152 to be replaced with a working one.

The connection conductor structure 154 in the embodiment shown in FIG. 22 to FIG. 24 also has the same structure as the embodiment of FIG. It is preferably formed by performing a secondary processing of cutting off the portion. FIG. 25 is a plan view showing a patterned conductor 170 before secondary processing suitable for use in the embodiment of FIGS. In this figure, parts corresponding to those in FIGS. 22 to 24 are denoted by the same reference numerals.

Like the patterned conductor 120 shown in FIG. 18, the patterned conductor 170 is also a long tape, and the connecting portion 16 connects the light source mounting portion 15 5 in the longitudinal direction. 0 extends in the longitudinal direction. Light source mounting part

The first and second trunk roads 1 6 1, 1 5 5 and the connecting road 1 6 0 are sandwiched in the width direction.

1 62 are arranged on both sides of the conductor 170. In addition, each terminal connection section 159 of each light source mounting section 155 is connected to the first and second main path sections 1 1 1 and 1 1 2 by the corresponding branch sections 16 3 and 16 4. Have been. The communication section 160 is connected to the terminals 153 of the adjacent different LEDs 155 (that is, included in the adjacent light source mounting section 155), and connects the pair of terminal connections 159 respectively. Includes multiple connections 1 7 1. The connecting member 165 formed by the insert mold is formed substantially at the center in the longitudinal direction of the connecting path 171 (see FIG. 22). At this time, a hole 169 is provided at a position of the connecting member 165 which is aligned with the connection path 171 so as to expose the connection path 171 (the connection path 171 exposed by the hole 169). The part of 1 is called the bridge part 17 1 A). As a result, after forming the connecting member 165, a punch (not shown) of the press machine is inserted through the hole 169 to cut off the bridge portion 171A, and the connection is made via the connection path 171. Terminal connection part 1 5 9 It becomes possible to divide. In this embodiment, the bridge portion 17 1 A exposed through the hole 16 9 is relatively wide so that the hole 16 9 of the connecting member 16 5 can be reliably exposed and easily cut off. It is formed narrow. Note that the shape of the bridge portion 1771A is arbitrary, and may include, for example, two narrow paths crossing a cross. Also, perforations may be made at appropriate locations on the connection path 17 1 to facilitate resection.

In this embodiment, a tongue piece 174 extending in the longitudinal direction is formed by cutting at a portion of the connection path 171 adjacent to the terminal connection portion 159 of the light source mounting portion 155. As shown in the perspective view of FIG. 22 and the cross-sectional view of FIG. 24, in the assembled state, the tongue piece 17 4 is bent, and the LED 15 2 attached to the socket 17 2 is held down from above. It serves to prevent 52 from undesirably dropping out of socket 17 2.

FIGS. 26 to 28 show that the patterned conductors 170 are secondarily formed from the patterned conductors 170 shown in FIG. 25 to form connection conductor structures 154 for series-parallel, parallel, and series connection. This shows the procedure for processing. As in FIGS. 19 to 21, the part to be resected is indicated by oblique lines. In addition, the sockets 172 and the connecting members 16.5 are shown by dotted lines so that the position of the cut portion can be easily understood. The description for FIGS. 26 to 28 is substantially the same as the description for FIGS. 19 to 21, and therefore will be omitted. As can be seen from these figures, various connection patterns can be obtained from the patterned conductor 170. It is possible to form the connection conductor structure 154.

FIG. 29 is a partial perspective view showing a modified embodiment of the embodiment shown in FIG. In this figure, the same parts as those in FIG. 22 are denoted by the same reference numerals, and detailed description is omitted. The light source connector 15 1 ′ differs from the embodiment shown in FIG. 22 in that a so-called side-view type LED 15 2 ′ having a light emitting portion 15 2 on the side is used as a light source. . Also LED 1 5 2 ' The socket 17 2 ′ in which the LED is mounted has a part of the side wall cut away to form an opening 17 6 so as not to obstruct the light emitted from the LED 15 2 ′. An opening is provided on both sides of the socket 17 2 ′ so that the LED 15 2 ′ can be mounted with its orientation changed, and light can be applied to both sides.

FIG. 30 is a partial perspective view showing another modified example of the embodiment shown in FIG. In this figure, the same parts as those in FIGS. 22 and 29 are denoted by the same reference numerals, and detailed description is omitted. In this light source connection body 151〃, the socket 172 "extends over the entire width of the connection conductor structure 154, and also serves as a connection member. In this way, it is possible to reduce the number of insert molds to reduce the manufacturing cost, and to use the side-view type LED 1 52 ′ as the light source as in the embodiment of FIG. In order to make the opening, a part of the side wall of the socket 172〃 is cut out to form an opening 176. Since the openings 176 are provided on both sides of the socket 172〃, FIG. It is also possible to mount the LED 152 'in the opposite direction to that shown in Fig. 2. It is of course possible to use a normal LED 152 as a light source.

FIG. 31 is a perspective view showing still another modified embodiment of the embodiment shown in FIG. In this figure, the same parts as those in FIG. Each terminal connection portion 15 9 ′ of each light source attachment portion 15 5 ′ of the connection conductor structure 1 54 ′ of the light source connection body 15 1 a has a pair of extension portions 17 5 extending in the width direction. Have. The widthwise extending portion 175 is bent by a press machine so as to be substantially perpendicular to the main surface of the connecting conductor structure 154 ′ to form a wall facing to the connecting conductor structure 154 ′. LED 15 2 can be assembled to the connection conductor structure 1 54 ^f . As a result, as shown in Fig. 22 Therefore, the formed socket 172 becomes unnecessary, and the manufacturing cost and work time can be reduced accordingly. Note that, similarly to the embodiment of FIG. 22, the chip type LED 152 electrically connected to the light source mounting portion 15 5 'of the connection conductor structure 1 54' The tongue 174 formed in the connection path 171 is raised and bent by a notch extending in the longitudinal direction in the vicinity of the connection part 159 ', and is pressed and urged from above by the tongue 174. This is preferable because undesired falling off can be prevented.

In the embodiment shown in FIG. 31, the LED 152 is not attached to the pair of terminal connection portions 15 9 ′ of the second light source attachment portion 15 5 ′ from the right. The sections 159 'are connected to each other by a bridge section 159A, and the two LEDs, the second LED 152 from the left and the LED 152 on the right, are connected in series. As will be described later in detail with reference to FIG. A bridge part 159 A connecting the connection part 159 ′ is formed, and in the secondary processing, only the bridge part 159 A in the light source mounting part 155 ′ to which the LED 152 is mounted is cut off. However, this can be realized by leaving the bridge portion 159 A of the light source mounting portion 155 ′ to which the LED 155 is not connected as it is. By doing so, it is possible to adjust the interval between the adjacent LEDs 152 in the completed light source assembly 151a. In the embodiment shown in FIG. 31, the LEDs 15 2 are all mounted on the same side (upper surface in the figure) of the connection conductor structure 15 4 ′, but the extension 17 5 and the tongue 17 By reversing the bending direction of 4, it is also possible to attach LED 152 to the other surface (the lower surface in the figure).

Further, in the embodiment shown in FIG. 31, a chip-type resistor (also referred to as a surface mount resistor) 156 is connected between the communication path section 160 and the second main path section 162. Have been. For this reason, the connection conductor structure 150 4 ′ of FIG. 31 includes the connection path section 160 at the connection path section 160 to which the resistor 156 is connected and the second trunk path section 16 2. And a pair of resistance terminal connection portions 178 extending from the trunk portion 162 toward each other. That is, a resistance mounting portion 177 is formed by the pair of resistance terminal connection portions 178. As with the (light source) terminal connection section 15 9 ′ for the LED 15 2, each resistance terminal connection section 17 8 is also bent by a press machine to form a pair of extension sections 17 It has nine. The chip-type resistor 156 is inserted between the opposed walls 179, and the pair of terminals 157 of the chip-type resistor 156 are welded to the resistor terminal connection portion 178 by, for example, laser welding (bonding). ) Is done. Laser welding is preferably performed by irradiating laser light to one or more points on the opposite side to which the resistor 156 of the resistor terminal connection 178 is attached. It is also possible to apply laser light from the side of the surface to be attached. By welding, it is possible to prevent the chip resistor 156 from undesirably dropping off from the connecting conductor structure 154 ′. It is preferable that the connection conductor structure 154 ′ be made of aluminum because such laser welding can be performed with high reliability. It is more suitable to tin-plate. In addition, arc welding, ultrasonic welding, spot welding (resistance welding), etc. are also conceivable, but the terminal 157 of the chip-type resistor 156 is usually very thin and easily damaged. Laser welding is preferred to reduce as much as possible. Although a conductive adhesive containing, for example, aluminum nitride powder can be used instead of welding, welding is generally preferred from the viewpoint of mechanical strength. In this way, by allowing the resistor 156 to be connectable between the communication path section 160 and the second trunk section 162, the resistor 156 is connected in series to the LED 152. It can be connected to prevent overvoltage from being applied to LED 152. In the embodiment shown in FIG. 31, the insert is formed so as to extend in the width direction of the connection conductor structure 15 4 ′ so as to connect the communication path section 160 and the pair of trunk sections 16 1, 16 2. The connecting member 165 'formed by the mold has the same length as the width of the connecting conductor structure 154'. As shown in FIG. 32, a widthwise depression 1666A or a through hole 1666B is formed in a part of the pair of trunk roads 161 and 162 later, as shown in FIG. A part of the connecting member 16 5 ′ formed by the sensor mold extends in the vertical direction in the figure through 66 A or the through hole 16 B, and the trunk roads 16 1 and 16 2 It is made possible by firmly connecting the connecting member and preventing the connecting member 165 'from shifting in the longitudinal direction.

FIG. 32 is a plan view of a patterned conductor 170 ′ used to form the light source assembly 151a of FIG. In this figure, the same parts as those in FIG. As shown, this patterned conductor 170 ′ has a plurality of light source mounting portions 155 ′, each of which can be mounted with a chip type LED 152, and each of the light source mounting portions 155 ′. The reference numeral 15 5 ′ has a pair of terminal connection portions 15 9 ′ corresponding to the pair of electric connection terminals 15 3 of the chip type LED 15 2. Each terminal connecting portion 15 9 ′ has a pair of widthwise extending portions 17 5 extending in opposite directions, and is a patterned conductor 17 5 when forming the connecting conductor structure 15 4 ′. By bending these extensions 175 during the secondary processing (press processing) of 0 ', a wall is formed to hold or position the chip-type LED 152 as shown in Fig. 31 You can do it. Notches (grooves) may be formed at the base of the extension portion 175 so that bending can be easily performed. In the patterned conductor 170 ′ in FIG. 32, as described with reference to FIG. 31, the bridge portion 1 59 ′ between the pair of terminal connection portions 159 ′ of each light source mounting portion 155 ′ is provided. Connected by 5 9 A to form a connecting conductor structure 1 5 4 ′ During the secondary processing of the patterned conductor 17 CT, only the bridge section 15 9 A of the light source mounting section 15 5 ′ to which the LED 15 2 is connected can be cut off. Further, in the patterned conductor 170 ', a part of the branch section 164 connecting the connecting path section 160 and the second trunk section 162 is partially connected to the connecting path section 160 and the trunk section. It has been replaced by a resistor mounting part 177 for connecting a chip type resistor 156 to the road part 162. Each resistor mounting portion 1 7 7 has a pair of resistor terminal connection portions 1 7 8 corresponding to a pair of electrical connection terminals 1 5 7 of the chip type resistor 1 5 6, and the patterned conductor 1 7 before secondary processing At 0 ′, the pair of resistance terminal connection portions 178 are connected to each other by the bridge portion 178 A, and only when the resistance 156 is actually connected, the bridge portion 178 in the secondary processing. 8 A is removed. If the resistor 156 is not connected and the bridge section 178 A is left, just like the normal branch section 164, the connection section 160 and the second trunk section 162 are simply connected. It will be understood that it functions as a conductor connecting the two. In the embodiment of FIG. 32, a part of the plurality of branch portions 164 is a resistor mounting portion 177, but all of the branch portions 164 may be a resistor mounting portion 177. In addition, in the embodiment of FIGS. 31 and 32, the resistance mounting portion 1777 for mounting the resistor 156 is provided between the communication path portion 160 and the second main road portion 162. However, it is of course possible to provide between the connecting path section 160 and the first trunk section 161.

Further, as described above, the patterned conductor 17 (T in FIG. 32 corresponds to the semi-circular width direction of the first main road 161 at a position corresponding to the position where the connecting member 16 5 ′ is provided. A recess 1666A is provided, and a through hole 1666B is formed in the second trunk section 162. In this manner, the connecting member 1 formed by the insert mold is formed. 6 5 ′ extends through these widthwise recesses 1 66 A and through holes 16 6 B, and the connecting member 16 5 ′ has the same width or the same width as the patterned conductor 170 ′. Concatenation, even for shorter lengths The member 16 5 ′ and the trunk roads 16 1, 16 2 can be firmly connected. In FIG. 32, the first trunk road portion 161 having a relatively small width is provided with a recess in the width direction, and the second trunk road portion 162 having a relatively large width is provided with a through hole. It is, of course, possible to do so. It is sufficient that a part of the connecting member 16 5 ′ can penetrate a part of these trunk roads 16 1 and 16 2 in the vertical direction. Of course, the shape of the widthwise recess 1666A and the through hole 1666B is arbitrary, and is not limited to a semicircle or a circle.

FIG. 33 is a partial plan view showing a modified embodiment of the patterned conductor of FIG. 18 suitable for forming a series connection of LEDs. In this figure, the same parts as those in FIG. As shown in the figure, the patterned conductor 120 ′ is connected to the first trunk section 111 and the first trunk section 111 shown in FIG. It does not have the branch section 113 to be connected, and its width is narrowed accordingly. By doing so, unnecessary materials can be saved when the light source assembly is completed, and costs can be reduced. Note that this patterned conductor 1 20 ′ is the same as the patterned conductor 120 of FIG. 18 except that it does not have the trunk section 1 1 1 and the branch section 1 13, and therefore, FIG. It can be processed by the same progressive press machine used for the patterned conductor 120 of FIG.

FIG. 34 is a partial plan view showing a modified example of the patterned conductor of FIG. 25 suitable for forming a series connection of LEDs. In this figure, the same parts as those in FIG. Similarly to the patterned conductor 120 ′ shown in FIG. 33, this patterned conductor 170 ° also does not have the first trunk portion 161 and the branch portion 163, and is made of material. Costs are being reduced through reductions.

FIG. 35 is a partial perspective view similar to FIG. 16 showing another embodiment of the connecting member. In this figure, the same parts as those in FIG. Description is omitted. In this light source connected body 101 ', a connecting conductor structure 104 (or a patterned conductor 120 ), A plurality of insulative sheets 184 made of, for example, vinyl chloride are used. The insulating sheet 184 can be attached to the patterned conductor 120 including the main roads 111, 112 and the communication path 110 before the secondary processing. It is preferable to use an adhesive for such attachment, but it is also possible to attach by any other appropriate method such as heat welding or UV curing of a resin. When such a sheet 184 is used, mechanical strength is inferior to the case where an insert mold is used, but the formed light source connecting body can be made smaller or thinner. The insulating sheet 184 can be punched together by a press machine during the secondary processing of the tape-shaped patterned conductor 120.

FIG. 36 is a partial perspective view similar to FIG. 16 showing still another embodiment of the connecting member, and FIG. 37 is a bottom view thereof. In these figures, the same parts as those in FIG. 16 are denoted by the same reference numerals, and detailed description is omitted. In this light source connected body 101, a connecting conductor structure 104 (or a patterned conductor 120) is used as a connecting member for connecting the two main road sections 111, 112 and the connecting path section 110. ), An insulating sheet 184 ′ made of, for example, vinyl chloride is used which extends over a predetermined length in the length direction. The insulating sheet 184 'may extend, for example, over the entire length of the patterned conductor 120. Such an insulating sheet 184 'is also attached to the patterned conductor' 120 using a suitable means such as an adhesive before the secondary processing of the patterned conductor '120. A hole may be formed in a predetermined portion of the insulating sheet 184 '(for example, a portion matching the pilot hole 118 and a portion where the lead wire 103 of the LED 102 is inserted). In this embodiment, 3 As shown in the bottom view of 7, the terminal for the connecting conductor structure 104 (or light source mounting) is connected so that the laser for laser welding can be applied from below. An opening 180 is provided to expose the part 105). In the embodiment shown in FIG. 36 as well, similarly to the embodiment using a plurality of insulating sheets 184 shown in FIG. Can be smaller or thinner. In addition, the work of attaching to the patterned conductor 120 can be performed relatively easily and in a short time as compared with the case where a plurality of insulating sheets 184 are used. In FIG. 36, the insulating sheet 18 4 ′ extends over the entire width of the connecting conductor structure 104 in the width direction, but the two trunk roads 1 1 1, 1 1 2 and the connecting road 1 As long as it can be connected to 110, it is not always necessary to extend over the entire width direction. For example, the width may be such that the pilot hole 118 is not closed.

As shown in FIG. 36, in the case of the light source connected body 101 〃 using the insulating sheet 184 ′ as a connecting member, as shown in FIG. 38, the two main road sections 1 1 1 1 1 1 2 Fold the branch roads 1 1 3 and 1 1 4 so that the main surface is perpendicular to the main surface of the connecting road 1 1 10 and attach the trunk roads 1 1 1 and 1 1 2 to the board (holding body) 1 8 By inserting into the matching grooves 18 1, 18 2 formed at 0, the light source connector 101 can easily be mounted on the mounting board 180. A groove or a hole may be provided in the mounting board 180 so as to receive, for example, the lead wire 103 of the LED 102 projecting from the lower surface of the light source connector 101 体. Further, the mounting port 180 may be formed integrally with the light source connector 101 by molding. Further, it is also possible to form a surface light source by arranging a plurality of light source connected bodies 101 on the mounting port 180 side by side in the width direction. At this time, it is preferable to adjust the pitches of the LEDs 102 in the vertical direction and the horizontal direction so that they are the same. The light source shown in Fig. 16 In the connecting body 101, the trunks 1 1 1 and 1 1 2 of the connecting conductor structure 104 and the connecting path 1 110 were connected by the connecting member 1 15 formed by insert molding. After installation on the connecting conductor structure 104 of 02, the two trunk roads 1 1 1 and 1 1 2 and the connecting road 1 110 are connected via the LED 102 and the branch roads 1 13 and 1 14. The connecting member 1 15 can be removed because of the body. In such a case, the light source connector 101 can be mounted on the mounting board in the same manner as shown in FIG. The same applies to the light source assembly shown in FIG.

FIG. 39 is a perspective view showing an embodiment 190 of a light emitting device using a light source connector 101 using, for example, the insulating sheet 184 ′ shown in FIG. 36 as a connecting member. Yes, FIG. 40 is a cross-sectional view along the line XL—XL, and FIG. 41 is a schematic top view. In these drawings, the same parts as those shown in FIG. 36 are denoted by the same reference numerals, and detailed description will be omitted. As shown in FIG. 41, in this example, each of the _N LED series blocks 1 ^ to LN included in the light source assembly 101〃 is composed of four LEDs 102 and these LEDs 1 Includes a chip-type resistor 1 56 (see Figure 31) connected in series to 0 2. The chip-type resistor 156 cuts a part of the communication path 110 (or connection path 121) between the adjacent LEDs 102, and the resistor 156 spans the cut part. 6 can be mounted and the terminal of the resistor 156 can be attached by laser welding to the connection path 121. The number of LEDs 102 included in each of the series blocks L i to L _N can of course be variously changed.

The illustrated light-emitting device 190 has a light-transmitting cylindrical tubular member 191, such as a glass tube, as a housing for accommodating the light source connector 101 '. By using a sufficiently small one as the LED 102, the tubular member 191, for example, has a diameter of 0.5 to 2 cm. And a thin thing can be used. The translucent tubular member 191 can be made of plastic or the like, but as described later in detail, a glass tube having good heat transfer characteristics is preferable for efficient heat dissipation.

Cap members 192 are attached to both ends of the tubular member 191, and each cap member 192 holds a pair of conductive pins 1993. One of a pair of conductive pins 193 provided at each end of the tubular member 191 is connected to the first trunk section 111 of the light source connector 101, and the other is connected to the first It is connected to 2 main roads 1 1 2. Thus, for example, by connecting a pair of conductive pins 193 provided at one end of the tubular member 191 to a power source, the light source connector is connected via the trunk roads 111, 112. The power supply voltage can be supplied to the LED 101 of 101〃.

As described above, according to the present embodiment, the trunks 1 1 1 and 1 1 2 of the light source assembly 100 1 できる can be used as wiring (or electric circuit) for connecting the LED 102 to the power supply. The work efficiency of assembling and the like can be greatly improved as compared with the case of wiring separately. Further, it is possible to connect another luminous device 190 through the corresponding conductive pin 193, and by repeating this, any number of luminous devices 190 can be connected. be able to. In this case, for example, the conductive pin 193 at one end is formed into a female shape and the conductive pin 193 at the other end is female so that the light emitting device 190 can be easily connected to each other. It may be a type. It is also possible to use a dedicated connector cable for connection. When the device 190 is used only as a single unit, the first and second trunks 1 1 1 and 1 1 2 of the light source connector 15 1 are connected to one end of the tubular member 19 1. Alternatively, it may be configured to be connected only to the conductive pin 193 provided in the device.

In the light emitting device 190 shown in FIGS. 39 to 41, heat is generated from the resistor 122 and the LED 102 when used. The tubular member 19 1 is Since both ends of the tubular member 1912 are sealed by the cap member 192, when the diameter of the tubular member 191 is as small as 0.5 to 2 cm, heat convection hardly occurs. Therefore, when a printed circuit board is used, the copper foil used to form the circuit is usually as thin as 35 m and has poor heat transfer efficiency (that is, the heat transfer speed is low). The heat generated from elements such as 2 remained in the surrounding area, and the temperature around the element was excessively increased, which could damage the element or reduce its performance. However, the light emitting device 190 shown in FIGS. 39 to 41 has a connection conductor structure 104 (FIG. 1) which can be formed by pressing (primary and secondary) a conductive flat plate material. The light source connected body 101) with (38) is used, and the thickness of the flat plate material is usually about 0.1 to 0.3 mm, which can be much larger than the copper foil of the printed circuit board. . Therefore, the heat conduction characteristics are extremely good compared to the printed circuit board, the heat generated in each element is released, and the temperature around the element is prevented from rising excessively, and the heat conduction is substantially uniform in the tubular member 19 1. A temperature distribution can be realized. Furthermore, a plurality of arc-shaped heat transfer plates 194 having elasticity, preferably made of metal such as aluminum, are welded to the first and second trunk road sections 111, 112, for example, by welding.取り付け Mounted with screws. The heat transfer plate 194 also functions as a support for supporting the light source connector 101 in the tubular member 191. As is well shown in the cross-sectional view of the figure, the heat transfer plate 1994 has a cross-sectional shape substantially along the inner surface of the tubular member 191, and is pressed against the tubular member 191 in close contact. As a result, heat is transmitted from the first and second trunk roads 11 1 and 1 12 to the tubular member 19 1 via the heat transfer plate 19 4, and further, the tubular member 19 1 made of glass is formed. Since heat is dissipated from the outside to the outside, the temperature rise in the tubular member 19 1 can be further suppressed. That is, the use of the heat transfer plate 1994 allows the tubular member 1911 itself to act as a heat sink. In addition, tubular members made of glass other than 19 1 In addition, when the light source connector 101 is housed in a housing (housing) made of an insulator having good heat transfer properties, such as ceramic, the heat transfer plate 1994 described above is used. Can be used to transfer heat to the housing and dissipate heat from the housing to the outside. Although a relatively small heat transfer plate 194 is used in the illustrated example, a heat transfer plate 194 extending over substantially the same length as the tubular member 191 may be used. Further, the shape of the housing is not limited to a tubular shape, and the shape of the heat transfer plate 194 can be variously changed according to the shape of the housing. Further, it is more preferable that the upper surface and the Z or a part or all of the lower surface of the light source unit 101 be black because heat can be radiated as infrared rays. This can be achieved, for example, by performing black nickel plating, black chrome plating, chromate treatment, or using black alumite as the material.

In the above embodiment, the individual light sources consisted of a single light-emitting element, such as a bullet-type LED 102 with two leads or a so-called chip-type LED 152 without leads. However, as described below, one light source may be formed of a light emitting element assembly including a plurality of light emitting elements.

FIG. 42a is a perspective view for explaining an embodiment using such a light emitting element assembly 195 as a light source. In this embodiment, as the connection conductor structure 104, as shown in FIG. 20, a tape-shaped patterned conductor 120 subjected to secondary processing for parallel connection of light sources can be used. In FIG. 42A, the same parts as those in the above embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. When a circuit for parallel connection is configured in this manner, a pair of terminal connection portions 109 of each light source attachment portion 105 of the connection conductor structure 104 are connected to the corresponding branch portion 1 13 or 1 respectively. Since each of them is connected to the trunk 1 1 1 or 1 1 2 through 1 4, each part of the connecting conductor structure 104 is separated The connecting member 115 is not required by the insert mold to prevent the occurrence.

In the embodiment of FIG. 42a, the light-emitting element assembly 195 as a light source is composed of six chip-type LEDs arranged in a row on a support 198 made of, for example, a printed circuit board and electrically connected. 196 and one chip-type resistor 197. Further, the light emitting element assembly 195 is separated at a distance corresponding to the pair of terminal connection portions 109 of each light source mounting portion 105 of the connection conductor structure 104, and serves as a terminal for electrical connection. It has a pair of leads or conductive pins 199 extending downward. The LED 196 and the resistor 197 of the light emitting element assembly 195 can be connected in series, for example, as shown in the circuit diagram of FIG. By doing so, by inserting the lead wire 199 into the connection hole 1 16 formed in the terminal connection portion 109, in the same manner as described in the embodiment of FIG. The light emitting element assembly 195 as a light source can be connected to the connection conductor structure 104. By allowing the light-emitting element assembly 195 to be attached to the connection conductor structure 104 as a light source in this manner, it is possible to widen the parallax of the lighting effect. For example, as shown in Fig. 42a, a plurality of light-emitting element assemblies 195 are used as light sources, and adjacent light-emitting elements are arranged so as to be close to each other in the longitudinal direction. By eliminating dark areas, more uniform and even illumination can be achieved. Instead of using a printed circuit board as the support 1998 to form the light-emitting element assembly 1995, the light-emitting element assembly 1995 may be connected to the light source assembly 15 shown in FIG. 22 or FIG. 31, for example. It is also possible to form using 1, 1 5 1 '.

FIGS. 43a and 43b show examples using another light emitting element assembly. Figure 43a shows such a light-emitting device assembly 1 95 'as the light source. FIG. 43B is a perspective view for explaining an embodiment of the light source assembly, and FIG. 43B is a circuit diagram of the light emitting element assembly 195 ′. In FIGS. 43a and 43b, the same parts as those in FIGS. 42a and 42b are denoted by the same reference numerals, and detailed description is omitted. This light-emitting element assembly 195 'is composed of a series connection of 6 LEDs 1960 and one resistor 197 connected in series, for example, 5 on a support 198' with a printed circuit board. It has a two-dimensional light emission. In this embodiment, similarly to the embodiment shown in FIG. 42, the LED 19 of the support 1 98 ′ is used as an electric connection terminal connected to the terminal connection portion 109 of the connection conductor structure 104. On a surface opposite to the surface on which the resistor 6 and the resistor 197 are mounted, there is provided a pair of lead wires or conductive pins 199 extending substantially in parallel at predetermined intervals. As shown, the light emitting element assembly 1 95 ′ may have the same width as the connecting conductor structure 104. In this way, when the light source assemblies using the light-emitting element assemblies 1 95 ′ are arranged side by side in the width direction, the distance between adjacent light source assemblies is appropriately adjusted to provide uniform illumination as a whole. be able to. In addition, it is preferable that the plurality of light emitting element assemblies 1 95 ′ are arranged without a gap in the longitudinal direction, because a dark portion between the light sources can be eliminated. Note that the shape of the light emitting element assembly 195 'is not limited to a square or a rectangle, but may be any other shape such as a circle. Further, in the above embodiment, the tape-shaped patterned conductor 120 subjected to secondary processing for parallel connection of the light source was used as the connection conductor structure 104, but the connection method of the light emitting element in the light emitting element assembly and the size of the resistance were large. By appropriately selecting the size and the like, it is of course possible to use those that have been subjected to secondary processing for other connections such as series-parallel connection and series connection (Figs. 19 and 21).

For example, in the light source connector 15 1 a shown in FIG. 31 using a chip-type LED 155 as a light source, the connection conductor structure 154 ′ is substantially flat and flexible. Therefore, it is possible to bend and use in the longitudinal direction. However, in the embodiment of FIG. 31, the pair of electrical connection terminals 15 3 of each chip type LED 15 2 (and the corresponding pair of terminal connection portions 15 9 ′ of the connection conductor structure 154 ′) are light sources. Since the connecting body 15 1 a (that is, the connecting conductor structure 1 5 4 ′) is arranged to be spaced apart in the longitudinal direction, when the light source connecting body 15 1 a is bent, the connecting conductor structure 1 A force can be exerted to separate the terminal connection part 15 9 ′ of 54 ′ and the terminal 15 3 of the LED 152. In the embodiment of FIG. 31, the LED 155 is held down from above by the tongue piece 174, but they are separated from the electrical contacts (that is, the terminal 153 and the terminal connection 159 ′). It is not preferable that such a force acts from the viewpoint of preventing poor connection. It is conceivable that the LED 155 and the connection conductor structure 154 'are welded by, for example, laser welding or the like, but it is similarly undesirable that such force acts.

The embodiment of the tape-shaped patterned conductor shown in FIG. 44 is adapted to avoid such problems. As shown in the figure, this patterned conductor 200 can also be formed by press working so as to have a predetermined pattern, similarly to the above-described embodiment, and is subjected to a secondary processing for cutting out an appropriate portion. As a result, a connection conductor structure having a required circuit configuration can be formed. That is, this patterned conductor 200 is composed of first and second trunk roads 211 and 212 extending substantially in parallel in the longitudinal direction, and a chip type LED 200 as a light source. A plurality of light source mounting portions 2 15 arranged in the longitudinal direction between the trunk roads 2 11 1 and 2 12 for electrical connection with the light source mounting portion 2 (see FIG. 45), and these light source mounting portions 2 15 A connecting path 2 1 0 that connects in the longitudinal direction, and a plurality of branch sections 2 1 3 and 2 1 4 that connect the connecting path 2 1 0 and the trunk 2 1 1 and 2 1 2 in the width direction By cutting off appropriate branch sections 2 13 and 2 14, chip-type LEs can be connected in various connection modes such as series, parallel, and series-parallel. A connection conductor structure for connecting D 202 can be formed.

In the embodiment of FIG. 44, each of the light source mounting portions 2 15 has a pair of light source terminal connections spaced apart in a direction substantially perpendicular to the longitudinal direction of the patterned conductor 200 (ie, in the width direction). It has a part 2 16. With this, when each chip type LED 202 used as a light source is mounted on the corresponding light source mounting part 215, as shown in FIG. 203 will be spaced apart in a direction generally perpendicular to the longitudinal direction of the patterned conductor 200 (ie, of the connecting conductor structure formed therefrom).

Each terminal connection portion 2 16 has a pair of extension portions 2 17 extending in the longitudinal direction of the patterned conductor 200. The extension portion 217 is bent perpendicularly to the main surface of the patterned conductor 200 similarly to the extension portion 175 of the embodiment shown in FIG. Form a wall for holding or positioning. In the illustrated example, the pair of terminal connecting portions 2 16 of each light source mounting portion 2 15 are separated from each other. However, as in the embodiment shown in FIGS. 31 and 32, they are connected to each other. In this case, the pattern conductor 200 may be cut off in the secondary processing only when the LED 202 is attached.

In the patterned conductor 200 of Fig. 44, the resistor mounting part 2 25 for mounting the chip-type resistor 205 (see Fig. 45) between the two light source mounting parts 2 15 on the left side of the figure is shown. Is provided. Similarly to the light source mounting part 215, the resistance mounting part 225 has a pair of resistance terminal connecting parts 226 spaced apart in the width direction of the patterned conductor 200. Each of the terminal connecting portions 226 has a pair of extending portions 227 extending in the longitudinal direction of the patterned conductor 200. This extension portion 227 is bent perpendicularly to the main surface of the patterned conductor 200 similarly to the extension portion 179 of the embodiment shown in FIG. Form a wall for retaining or positioning the anti-205. By providing the resistor mounting portion 2 25 in this way, it is possible to easily realize the connection of the adjacent LED 202 via the resistor 205, and the pair of terminals 20 6 of the mounted resistor 205 is formed. The patterned conductors 200 are spaced apart in a direction substantially perpendicular to the longitudinal direction. It should be noted that, when forming the patterned conductor 200, the pair of resistance terminals 226 of the resistor mounting portion 222 is connected, and only when the resistor 205 is mounted, the patterned conductor 200 It is the same as the light source mounting part 215 that can be separated in the next processing.

Further, in the patterned conductor 200 of FIG. 44, the first and second trunk roads 211, 212 extend in the longitudinal direction while meandering. More specifically, the trunk roads 2 11 1 and 2 1 2 are arranged such that a portion substantially aligned in the longitudinal direction with the light source mounting portion 2 15 to which the LED 202 is mounted is directed outward in the width direction (that is, the communication path portion). (In a direction away from 210) to form a convex curved portion 211A, 212A. In addition, although each of the convex curved portions 211A and 212A is curved in a substantially U-shape in the drawing, it may be curved in an arc shape, for example. As a result, the convex curved portions 2 11 A and 2 12 A of the trunk roads 2 1 1 and 2 12 are bent at their roots to become substantially perpendicular to the main surface of the communication road 2 10 In this way, the bent part can be used for mounting on a support plate or the like (see Fig. 45). In addition, in the patterned conductor 200, since the trunk roads 211 and 212 are formed to be relatively narrow, a tape-shaped patterned conductor 200 progressive press machine (not shown) In order to facilitate handling at the same time, the edge bar 219 provided with the pilot hole 218 engaging with the pilot pin of the progressive press machine is separately provided extending in the longitudinal direction. It is connected to the road section 212 by a plurality of connecting sections 220. This edge cross section 219 is used, for example, in the final step of secondary processing of the tape-shaped patterned conductor 200 by a press machine. In this case, the connection part 220 is cut off from the second trunk road part 212 by cutting it off.

FIG. 45 is a perspective view of a light source connected body 201 formed by using the patterned conductor 200 shown in FIG. 44 and a holding body 230 for holding the same. As shown in the figure, the light source coupling body 201 is formed by cutting a predetermined portion of the patterned conductor 200 shown in FIG. 44 and forming a connection conductor having a required circuit configuration. A chip type LED 202 and a chip type resistor 205 are assembled to the structure 204. More specifically, a pair of longitudinally extending portions 217 of each light source terminal connecting portion 216 of the connection conductor structure 204 are bent to form opposing walls, and a chip type LED 202 as a light source is interposed therebetween. Inserted and attached. Since a pair of terminal connecting portions 2 16 for each LED 202 are arranged apart from each other in the width direction of the light source connected body 201, a pair of electric connection of each LED 202 in the mounted state is provided. It will be understood that terminals 203 are also located along the width direction. In this embodiment, since the tongue piece 174 as shown in FIG. 31 for suppressing the LED 202 from the upper side is not provided, the connection between the terminal connection part 2 16 and the terminal 203 of the LED 202 is not performed. For example, it may be performed by welding such as laser welding. Similarly, the chip-type resistor 205 is attached to a resistor attachment portion 225 provided between the light source attachment portions 215. The pair of longitudinally extending portions 2 27 of each of the resistor terminal connection portions 2 26 of the resistor mounting portion 2 25 are also bent to form opposing walls, and the chip-type resistor 205 is formed of these opposing walls 2 2 Inserted between 27. The connection between the terminal 206 of the chip-type resistor 205 and the terminal connection part 222 can also be performed by welding such as laser welding, similarly to the chip-type LED 202. When the chip-type LED 202 and the chip-type resistor 205 are mounted on the same surface of the connection conductor structure 204, the laser can be applied only from one side, which simplifies the manufacturing apparatus, which is preferable. Note that in FIG. 45, the leftmost LED 202 and resistor Although 205 is shown separated from the connection conductor structure 204 formed by cutting out the required portion of the patterned conductor 200, in practice, the LED 202 and the resistor 205 are shown. After assembling to the patterned conductor 200 by welding, the required portions (branch portions 2 13 and 21) of the patterned conductor 200 are cut off to form a connection conductor structure. Each part of the conductor structure 204 does not have to be separated. Alternatively, the insulating sheets 18 4 and 18 4 ′ may be connected to the patterned conductors 2, as shown in FIGS. 35 and 36, so that the parts of the connecting conductor structure 204 are not separated. After sticking to the pattern conductor 00, a required portion of the patterned conductor 200 may be cut off.

As described above, the first and second trunk road portions 211, 212 of the tape-shaped patterned conductor 200, the convex curved portions 211A, 212A are located at the roots thereof. It is bent substantially perpendicularly to the main surface of the light source unit 201. As shown in FIG. 45, the bent convex curved portions 211 A and 212 A are, for example, tightly fitted in corresponding grooves 2 31 formed in a flexible holder 230. Thus, the light source connector 201 can be attached to the holder 230 to form the light emitting device 240.

FIG. 46 is a schematic perspective view showing a state in which the light emitting device 240 thus formed is bent in the longitudinal direction. In this figure, the connecting conductor structure 204 is not shown. As shown in FIG. 46, each LED 202 has a pair of terminals 203 arranged along the width direction of the light-emitting device 240, so that the light-emitting device 240 is elongated. It will be appreciated that flexing in the direction does not create a force that separates the terminal 203 of the LED 202 from the terminal connection 2 16 of the connecting conductor structure 204.

FIG. 47a is a plan view showing still another embodiment of the tape-shaped patterned conductor, FIG. 47b is a cross-sectional view taken along line A--A of FIG. 47a, and FIG. Fig. 47 Connection conductor formed by cutting out the required part of the patterned conductor of 7a FIG. 2 is a plan view of a light source assembly formed by attaching a chip-type LED and a chip-type resistor to a body structure. The patterned conductor 250 shown in Fig. 47a is composed of a plurality of series blocks consisting of four chip-type LEDs 255 and one chip-type resistor 255 connected in series. The structure is suitable for manufacturing a series-parallel light source connector 2 51 (see Fig. 47c) that is connected and configured.

As shown in FIG. 47a, the tape-shaped patterned conductor 250 is formed of the first and second trunk roads 2 extending substantially parallel to the longitudinal direction, similarly to the above-described embodiment. A plurality of light source mounting portions 2 arranged longitudinally between these trunk routes 2 6 1 and 2 6 2 for electrical connection between 6 1, 2 62 and the chip type LED 25 2 as a light source 65, a communication path section 260 connecting these light source mounting sections 2 65 in the longitudinal direction, a communication path section 260, and the first and second trunk paths 2 61, 26 2. It has branch portions 26 3 and 26 4 connected in the width direction. Further, in this embodiment, a resistor mounting portion 275 for mounting a chip-type resistor 255 is formed between the second and third light source mounting portions 265 from the left in the figure. Each light source mounting section 2 65 has a pair of terminal connection sections 2 66 corresponding to a pair of terminals of the chip type LED 25 2, and the resistance mounting section 2 75 similarly has a pair of terminals of the resistance 2 5 5. It has a pair of terminal connection portions 276 corresponding to the above. In this embodiment, the adjacent light source mounting portion 265 and the resistor mounting portion 275 in the series block are connected by the communication path portion 260, and the adjacent light source mounting portions included in different series blocks are connected. The interval between 2 and 5 is divided in advance. Further, in this embodiment, since the first and second trunk roads 261, 262 are formed relatively thin, the pilot pins of the progressive press (not shown) for performing progressive press are used. An edge bar 269 extending in the longitudinal direction having a pilot hole 268 to be engaged is provided, and the edge bar 269 is connected to the second trunk road by a connecting portion 270. 2 6 Connected to 2.

In this embodiment, each terminal connection portion 266 of each light source mounting portion 265 is provided with a projection 267 for positioning the LED 252. Similarly, each terminal connection portion 276 of the resistor mounting portion 275 is provided with a protrusion 277 for positioning the resistor 255. These projections 267 and 277 form, for example, widthwise cuts in the terminal connection portions 26 6 and 2776 at positions matching the ends of the LED 255 or the resistor 255 to be mounted. Regarding the notch, it can be suitably formed by raising the terminal connection part 26 6, 27 6 on the opposite side to the side where the LED 252 or the resistor 255 is attached with a press machine. 47b). By providing such protrusions 267 and 277, the LED 255 and the resistor 255 can be easily positioned on the patterned conductor 250. Then, after connecting the LED 252 and the resistor 255 to the patterned conductor 250 by, for example, laser welding, a required portion of the patterned conductor is cut off to form a connection conductor structure 254 having a required circuit pattern. Then, the light source connected body 25 1 can be formed (FIG. 47c). As another method, as in the embodiment shown in FIG. 36, an insulating tape 184 ′ is attached to the tape-shaped patterned conductor 250, and then a required portion of the patterned conductor 250 is formed. May be cut off to form a connection conductor structure 254, and an LED 255 and a resistor 255 may be attached to the connection conductor structure 254. It is of course possible to use a connecting member extending in the width direction, such as the connecting member 115 shown in FIG. 16 or the like, to prevent the individual portions of the connection conductor structure 254 from being separated.

In the above embodiment, the light source is a bullet type LED 102 having two lead wires as terminals for electrical connection, or a chip type LED 152, 15 2 ′ having a pair of electrodes integrated with the main body. A light emitting device assembly having two, two, two or two lead wires, a so-called "2" However, today, for example, the so-called "three-pole LED lamp", which has two or three LED terminals emitting light of different colors and has three or four electrical connection terminals, for example, Also known as "4-pole LED lamps" are tape-shaped patterned conductors that can be applied to such 3-pole or 4-pole LED lamps and connection conductor structures formed from such patterned conductors. Advantageously, there is a light source combination formed by combining a 3 pole or 4 pole LED lamp.The following example describes a light source combination using such a 3 pole or 4 pole LED lamp. It is for realizing.

FIG. 48a is a front view of a typical 3-pole LED lamp 302, and FIG. 48b is a circuit diagram thereof. As shown, the three-pole LED lamp 302 includes two LED chips that emit light in different colors, for example, yellow and red, and the power sources of these two LED chips are connected to each other to form the first LED chip. It can be connected to the outside through the lead wire 303A. The anode of one LED chip can be connected to the outside through the second lead wire 303B, and the anode of the other LED chip can be connected to the outside through the third lead wire 303C. In the illustrated example, the power sources of the two LED chips are connected to each other, but the anodes may be connected to each other.

FIG. 49 is a partial plan view of a tape-shaped patterned conductor 300 suitable for forming a light source assembly using a plurality of three-pole LED lamps 302 shown in FIG. 48 as light sources. As shown in the figure, the patterned conductor 300 has a plurality of light source mounting portions 3 15 arranged in the longitudinal direction for mounting a three-pole LED lamp 302 as a light source. These light source mounting sections 3 15 are connected in the longitudinal direction by a communication path section 3 10. In detail, each light source mounting part 3 1 5 is a 3 pole LED lamp The first to third terminal connections 316A, 316B, 316C aligned in the width direction corresponding to the lead wires 303A, 303B, 303C A plurality of first connection paths 32 1 A for connecting the first terminal connection sections 3 16 A of the adjacent light source attachment sections 3 15 to each other; A plurality of second connection paths 3 2 1 B connecting the second terminal connection sections 3 16 B of the mounting section 3 15 to each other, and a third terminal connection section of the adjacent light source mounting section 3 15 And a plurality of third connection paths 321C connecting the 316Cs to each other. Also, as shown, the terminal connections 316 A, 316 B, and 316 C have the same lead wires 303 A, 3 A cross-shaped hole 317 for inserting and holding 03B and 303C is formed.

Furthermore, the first and second trunk paths 311 and 312 are arranged in the longitudinal direction on both sides of the patterned conductor 300 with the light source mounting section 315 and the communication path section 310 sandwiched in the width direction. Extends. These first and second trunk roads 3 1 1 and 3 1 2 are positioned at both ends in the width direction of the light source mounting portion 3 15 by branching roads 3 13 and 3 14 extending in the width direction. Are connected to the second and third connection paths 321 B and 321 C connecting the terminal connection sections 316 B and 316 C to be connected. Further, a pilot hole 318 is formed in the second trunk road 312 so as to be able to be handled by a progressive press machine (not shown).

In this embodiment, a chip type is provided between the terminal connection portions 316B, 316 <3 located at both ends in the width direction of each light source mounting portion 315 and the trunk road portions 311, 312. A resistor mounting portion 325 for mounting a resistor is provided. As shown in the figure, each resistor mounting section 3 25 faces each other from the terminal connection sections 3 16 B and 3 16 C of the light source mounting section 3 15 and the corresponding trunk sections 3 1 1 and 3 12. As in the embodiment shown in FIG. 31, each of the resistance terminal connections 3 26 is formed by a press machine. And a pair of extending portions 327 extending in opposite directions so as to be bent to form opposing walls.

A required portion of the patterned conductor 300 having such a structure is cut out to form a connection conductor structure, and a three-pole LED lamp 302 as a light source is attached to the corresponding light source attachment part 3 15 and a connection conductor structure is formed as shown in FIG. Connect the chip resistor 3 05 (see the circuit diagram in Figure 51) similar to the resistor 205

By attaching to the light source 25, the light source connected body 301 can be obtained. Figure 50 shows an example of such an ablation pattern. In this figure, the parts to be removed are indicated by oblique lines. FIG. 51 shows a circuit diagram of the formed light source unit 301. As shown by the dotted line in Fig. 51, connect the low voltage side of the DC power

FIG. 52a is a top perspective view of a typical 4-pole LED lamp, FIG. 52b is a bottom perspective view thereof, and FIG. 52c is a circuit diagram thereof. As shown in FIGS. 52a and 52b, this 4-pole LED lamp 402 is a chip-type LED (surface mounting LED) having no lead wire as a terminal. Further, it has a light emitting portion 402 A on the upper surface. 4 poles as shown in Fig. 5 2c The LED lamp 402 includes first and second LED chips that emit light in different colors, for example, yellow and red, and a four-pole LED lamp 402 It has four terminals 403 connected to the sword, respectively. Two of these terminals 403, which are connected to the cathodes of the first and second LED chips, are connected to one end of the 4-pole LED lamp 402 at the ends of the first and second LED chips. The two terminals connected to the node are located at the other end. Thus, the anode and cathode of each of the first and second 'LED chips included in the four-pole LED lamp 402 can be connected to the outside through the corresponding terminal 403.

FIG. 53 shows a tape-shaped patterned conductor that can be used to form a light source assembly using a plurality of 4-pole LED lamps 402 as shown in FIGS. 52 a to 52 c. 3 is a partial plan view of FIG. As shown in the figure, the patterned conductor 400 has a light source mounting portion 415 arranged in a longitudinal direction for mounting a 4-pole LED lamp 402 as a light source. The section 4 15 is communicated in the longitudinal direction by the communication section 4 10. More specifically, each light source mounting portion 41 5 has four terminal connection portions 4 16 corresponding to the four terminals 403 of the four-pole LED lamp 402, and two of these terminal connection portions 4 16 The two poles are arranged longitudinally so as to be connected to a pair of terminals 403 corresponding to the first LED chip included in the four-pole LED lamp 402, and the other two are included in the second pole included in the four-pole LED lamp 402. Are arranged in the longitudinal direction so as to be connected to a pair of terminals 403 corresponding to the first LED chip, and are separated in the width direction from the two terminal connection portions corresponding to the first LED chip. Further, the communication path section 4 10 includes a plurality of first and second connection paths 42 1 A and 42 1 B for connecting the terminal connection sections 4 16 aligned in the width direction included in the adjacent light source mounting sections 4 15. To Have. The first connection path 42 1 A connects the terminal connection sections 4 16 corresponding to the first LED chips included in the 4-pole LED lamp 402 in the longitudinal direction, and the second connection path 42 1 B The terminal connection portions 4 16 corresponding to the second LED chips included in the 4-pole LED lamp 402 are connected in the longitudinal direction. Therefore, the first connection path 421A and the second connection path 421B are separated in the width direction. Further, the first connection path 421A and the second connection path 421B which are aligned with each other in the longitudinal direction are connected in the width direction by the branch path 422.

Further, the first and second trunk road sections 41 1 and 41 2 extend in the longitudinal direction with the light source mounting section 4 15 and the communication path section 410 interposed therebetween in the width direction. These first and second main roads 4 1 1 and 4 1 2 are divided into first and second connection paths 42 1 A and 42 1 by branch paths 4 13 and 4 14 extending in the width direction, respectively. Connected to IB. The second trunk path portion 4 1 2, in _c yet this embodiment the pilot holes 41 8 for enabling the handling of the progressive press machine (not shown) is formed, the first stem A third trunk road portion 419 is provided outside the road portion 411 in the width direction, and is connected to the first trunk road portion 411 by a branch passage portion 420 extending in the width direction.

A required portion of the patterned conductor 400 having such a structure is cut off to form a connection conductor structure, and a four-pole LED lamp 402 as a light source is attached to the corresponding light source attachment part 415 and the resistance is reduced. By attaching the light source at a predetermined position, a light source connected body 401 using the four-pole LED lamp 402 can be obtained. An example of such an ablation pattern is shown in FIG. In this figure, the part to be resected is indicated by oblique lines. Also, the attached 4-pole LED lamp 402 and chip-type resistor 405 are shown by dotted lines. FIG. 55 is a circuit diagram of the light source connected body 401 thus formed. In this example, three 4-pole LED lamps 402 and two resistors 405 form one circuit unit, and one end of each circuit unit has first and second connection paths 4. 21A and 421B are both coupled to the first trunk 411, and at the other end, one of the two resistors 405 is connected to the first connection 421A and the third trunk. The other of the two resistors 405 is connected between the second connection path 42 1 B and the second trunk section 4 12. It should be understood that the number of 4-pole LED lamps 402 that can be included in each circuit unit is not limited to three.

As shown by the dotted line in Fig. 55, the high-voltage side of the DC power supply is connected to the first trunk road section 411 and the low-voltage side is connected to the third trunk path section 4 19 via the switch SW1. Then, by connecting to the second trunk road section 4 1 2 via the switch SW2, when the switch SW1 is closed, the LED chip (first LED chip) on the upper side of the figure of each 4-pole LED lamp 402 is shown. When the switch SW2 is closed, the LED chip (the second LED chip) on the lower side of the figure of each 4-pole LED lamp 402 can emit light when the switch SW2 is closed. Therefore, when the light emission color of the upper LED chip and the light emission color of the lower LED chip of each LED 402 are different, the light emission color can be changed by controlling the switches SW1 and SW2.

FIG. 56 is a partial plan view showing still another embodiment of the tape-shaped patterned conductor according to the present invention. The patterned conductor 500 has light source mounting portions 515 arranged in a longitudinal direction for mounting a light source, and these light source mounting portions 515 are formed in a longitudinal direction by a communication path portion 510. Has been contacted. Each light source mounting portion 5 15 has a pair of terminal connection portions 5 19 corresponding to a pair of terminals of the light source, and the pair of terminal connection portions 5 19 are separated from each other in the longitudinal direction. Each terminal connection 5 19 has a cross-shaped hole for inserting the lead wire 103 when the light source is, for example, a gun-type LED 102 as shown in FIG. 5 1 6 is formed. If the light source is a chip LED 152 as shown in Figure 31, LED 152 is simply a laser. ■ It can be attached to the terminal connection part 519 by one-side welding. The connection path section 5 10 has a plurality of connection paths 5 21 for connecting the terminal connection sections 5 19 included in the adjacent light source mounting section 5 15. It can also be said that a connection piece is formed by one connection path 521 and a pair of terminal connection parts 519 connected thereby. A part of each connection path 5 21 has a relatively narrow bridge portion 5 21 A for easy cutting, and the bridge portion 5 21 A is cut off to connect. The terminal connection portion 5 19 connected by the path 5 21 can be separated. In addition, the first and second trunk roads 5 1 1 and 5 1 2 are arranged on both sides of the patterned conductor 500 with the light source mounting section 5 15 and the communication path 5 110 sandwiched in the width direction. ing. Each terminal connection portion 5 19 of each light source mounting portion 5 15 is either the first trunk portion 5 1 1 or the second trunk portion 5 1 2 depending on the corresponding branch portion 5 13 3 5 1 One of the pair of terminal connections 5 19 in each light source mounting section 5 15 is connected to the first trunk section 5 11 1, and the other is connected to the second trunk section 5 12. It is connected. Of course, the branch sections 5 13 and 5 14 may be provided so that each terminal connection section 5 19 is connected to both the first and second trunk sections 5 11 and 5 12.

In this embodiment, in order to easily and surely attach a resistor having a pair of leads, such as the resistor 122 shown in FIG. 16, the connecting path 52 1 and the second trunk section 5 12 A cross-shaped hole 5 23 for inserting a lead wire of a resistor is formed. As shown by the dotted line in FIG. 56, the lead wire 52 2 A of the resistor 52 2 is inserted into these holes 52 3 (preferably further laser-welded) so that the resistance 52 2 2 Between the terminal connection section 5 19 and the second trunk section 5 12 or between adjacent terminal connection sections 5 19 included in any adjacent light source mounting section. be able to. If a resistor 5 2 2 is installed, the corresponding bridge 5 2 1 A or branch 5 1 4 Needless to say resection. In this embodiment, the bridge portion 52 1 A is shifted from the widthwise center of the connection portion 52 1 so that the bridge portion 52 21 A or the branch portion 514 can be cut after the connection of the resistor 52 2. The resistor mounting holes 5 2 3 are arranged so that when the resistor 5 2 2 is mounted, the resistor 5 22 does not overlap with the bridge 5 2 1 A or branch 514. Is formed.

For example, in the connection conductor structure (Fig. 21) in which the tape-shaped patterned conductor 120 of Fig. 18 is secondary-processed for serial connection of the light source (Fig. 21), each terminal mounting portion 109 and both trunk roads 1 1 Branches 1 13 and 1 14 connecting 1 and 1 12 have been removed. Therefore, when the LED 102 (Fig. 16) is connected by such a connecting conductor structure and a current flows through the LED 10, the heat generated by the connection will cause the heat generated by both trunks 1 1 1 and 1 1 2 And the ambient temperature of the LED 102 may be undesirably high. The secondary processing method of the patterned conductors 120 shown in Fig. 57 enables the heat dissipation through the trunks 1 1 1 and 1 1 2 while connecting the LEDs in series. This is to prevent the ambient temperature from rising. In FIG. 57, the same parts as those in FIG. 18 are denoted by the same reference numerals, and detailed description is omitted.

As shown in Figure 57, in this example, instead of cutting off the branches 1 13 and 1 14, cut off the shaded portions of the trunks 1 1 1 and 1 1 2 . As a result, a pair of terminal connection portions 109 and 109 in each light source mounting portion 5 are electrically separated from each other so that the LED 102 (FIG. 16) can be connected in series while connecting each terminal. The unit 109 can be kept connected to the main roads 111 and 112. In this way, in this embodiment, the heat generated when a current is applied to the LED 102 is quickly dissipated from the trunks 1 1 1 and 1 1 2 and the area around each LED 102 is It is possible to prevent the temperature from undesirably rising due to the accumulation of heat. In the example shown, each terminal connection 1 Although 09 is connected to both trunk roads 111 and 112, it may be connected to only one of them.

For example, as in the embodiment shown in FIG. 39, when the light source device is formed by housing the light source connector in a glass tube or the like having a light transmitting property, when the inner diameter of the glass tube is small (for example, about 5 mm), patterned conductors with narrow trunks must be used. Such a patterned conductor 550 is shown in Figure 58a. The patterned conductor 550 is a terminal connecting portion 569 that forms a light source mounting portion 565 for mounting a light source (not shown), and a communication connecting the light source mounting portion 565 in a longitudinal direction. A road section 560, a pair of trunk road sections 561, 562 extending in the longitudinal direction with the light source mounting section 565 and the connecting path section 660 sandwiched in the width direction, and a light source mounting section 5 The point that it has a plurality of branch portions 563 and 564 extending in the width direction that connects 65 to the trunk roads 561 and 562 is the same as the above-described embodiment. The feature is that the width of the main roads 561, 562 is becoming narrower. Therefore, it can be housed in a glass tube with a small inside diameter.However, the ends of these trunk roads 561, 562 can be connected to an external power source such as the conductive pin 93 shown in Fig. 39. It is difficult to attach an electrode pin for use. Fig. 58b shows a method for attaching electrode pins to the ends of the narrow trunk roads 561, 562 of the patterned conductor 550 as shown in Fig. 58a. The end conductor is 570. The end conductor 570 is a pair of narrow portions 571, 572 for connection with the trunks 561, 562 of the patterned conductor 5550, and It has a pair of wide portions 573, 574 connected to the narrow portions 571, 572, respectively. Holes 573 A and 574 A that can be used for attaching electrode pins are formed in each of the pair of wide portions 573 and 574. The end conductor 570 is laser welded with its pair of narrow portions 571, 572 superimposed on the corresponding trunks 561, 562 of the patterned conductor 550. More preferably pattern Integrated with the conductive conductor 550. The pair of wide portions 573 and 574 of the end conductor 570 are connected to each other by a bridge portion 575, but are separated by cutting off the bridge portion 575 before use. . By using the end conductor 570 having the pair of narrow portions 571, 572 and the pair of wide portions 573, 574 in this manner, the narrow trunk road portion 561, An electrode pin can be easily attached to the personalized conductor 550 having 562 as well.

In the example shown in Fig. 36, the parts of the connecting conductor structure 104 obtained by the secondary processing of the patterned conductor 120 are prevented from being separated or the mechanical strength of the connecting conductor structure 104 is increased. To facilitate handling, an insulating sheet 18 4 ′ was attached to the surface of the patterned conductor 120 opposite to the light source mounting surface. However, as in another embodiment 10 la of the light source connected body shown in FIG. 59, for example, the insulating sheet 18 4 ′ is attached to the light source mounting surface of the patterned conductor 120 (connection conductor structure 104). It can also be attached by heat welding. In this figure, the same parts as those in FIG. 36 are denoted by the same reference numerals, and detailed description is omitted. As shown in the figure, the insulating sheet 18 4 ′ is formed with an opening 18 5 at a predetermined position, as in FIG. 36, and the light source (LED) 2 and the patterned conductor are formed. Connection with the terminal connection section 109 of 120 is possible. The opening 185 may be formed before the insulating sheet 184 ′ is attached to the patterned conductor 120, or may be formed by pressing, laser processing, or the like after the attachment. It can also be formed by the method described above. In this way, when the insulating sheet 18 4 ′ is attached to the light source mounting surface of the patterned conductor 120, the portion to which the power supply voltage is applied is exposed on the light source mounting surface that is relatively easy for an operator to touch. The safety can be improved because it is not performed, and the lighting efficiency can be increased by reflecting the light from the light source 102 with the insulating sheet 18 4 ′.

As described above, the connection conductor formed by the secondary processing of the patterned conductor When using the insulating sheets 184 and 184 'to prevent the parts of the body structure 104 from falling apart, the mechanical strength of the obtained light source unit 1001', 101〃 and 101a is obtained. It is preferable to attach to the holder to compensate for. In addition, when assembling the light source 102 to the patterned conductor 120 and then cutting out the required portions to form the connecting conductor structure 104 to obtain a light source connected body, connecting the insulating sheet 184 'etc. It is not necessary to use a member, but it is more preferable to use a holder because the mechanical strength of the light source connection body is further reduced. FIG. 60a shows a preferred embodiment of such attachment of the light source assembly to the holder. FIG. 60B is a cross-sectional view showing a state where the light source connector is attached to the holder.

As shown in FIG. 60a and FIG. 60b, the holder 580 has a groove 582 extending in the longitudinal direction at the center, and opposing side walls 583, 583 of the groove. Has a pair of opposing longitudinally extending guide grooves 583A and 583A corresponding to a pair of trunk sections 1 1 1 and 1 1 2 of the connected light source body 101b. Have been. In this example, the connected light source 101b is formed using a patterned conductor 120 as shown in FIG. 18 but does not have a connecting member and has an extension 1 1b. The lead wire 103 is not caulked by bending the 7 and the lead wire 103 is connected to the patterned conductor 120 by laser processing, and the bottom surface is almost flat (Fig. 60b). . As shown in Fig. 60a, the pair of trunk roads 1 1 1 and 1 1 2 of the light source assembly 101 b are fitted into the corresponding guide grooves 583A and 583A. By sliding in the direction indicated by the arrow, it is possible to easily attach the light source connector 101b to the holder 580. Then, as shown in FIG. 6Ob, the portion to which the power supply voltage is applied is exposed on the light source mounting surface of the light source connection body 101b, and undesired short-circuiting due to dust or the like is prevented. In order to prevent this, a force bar member 585 made of an insulator is attached. An opening is provided in advance in the power par member 585 in accordance with the position of the light source 102. As shown in Figure 59 As described above, when the insulating sheet 184 'is attached to the light source mounting surface, the cover member 585 may be omitted.

FIG. 61 is a cross-sectional view showing another embodiment of the holder. The connected light source 101b is the same as that shown in FIGS. 60a and 60b. This holding body 590 has grooves 592 and 596 extending in the longitudinal direction on both the upper surface and the lower surface, and has a substantially H-shaped cross section. Opposing side walls 593, 593 and 597, 597 of each groove 592, 596 have a pair of trunks 1 1 1 and 1 1 2 of the associated light source assembly. Guide grooves 593 A, 593 A, 597 A, and 5977 A to be fitted are formed. By using such a holder 590, it is possible to attach the light source connector 101b to each of the upper surface and the lower surface of the holder 590 and irradiate light to both the upper and lower sides. Becomes

As described above, the patterned conductor (120, 200, etc.) according to the present invention can be preferably formed by a progressive press machine, but can also be formed by photoetching. A preferred method of forming a patterned conductor by such photoetching to obtain a light source assembly is shown in FIGS. As shown in Fig. 62a, for example, a heat welding sheet 63 is sandwiched between a conductive plate 601 made of phosphor bronze and an insulating plate 602 having substantially the same size, and pressed at a high temperature. Then, the conductive plate 601 is bonded to the insulating plate 602. Then, using photoetching, a plurality of long patterned conductors 6 04-1, 6 0 4 — each having a pattern as shown in FIG. 56, for example.

2 6 0 4— forms N. In FIG. 62B, detailed illustration of the formed pattern is omitted. Apart from the photo-etching process, a punching process for inserting a light source or a lead wire of a resistor may be performed by a press process or the like. In this state, all of the plurality of patterned conductors 604-1, 604-2,..., 604-N are attached to the insulating plate 602. After that, each patterned conductor 6 0 4—1, 6 0 4- Cut off the appropriate portion of 264-N to form the desired connecting conductor structure, attach light source 606 (and resistor if necessary) to the connecting conductor structure as shown in Figure 62c, 6 0 5— 1, 6 0 5-2 6 0 5—

Form N. In FIG. 62C, a plurality of light source connected bodies 655-1, 655-2,..., 655-N connected by an insulating plate 62 form a surface light source. You can see that. After or before mounting the light source 606, cut off the insulating plate 602 and connect the light source (connection conductor structure) 605—1, 605—2,..., 605—N Can of course be separated from one another.

In the above embodiment, a plurality of light sources (101, 101 ′, 101〃, 2102) in which a plurality of light sources are arranged in a line using patterned conductors (120, 200, etc.). 0 1). However, patterned conductors for forming a light source assembly comprising multiple rows of light sources are also possible. FIG. 63a is a partial plan view showing one embodiment of a patterned conductor capable of forming a light source assembly including two rows of light sources as an example. As shown in the figure, the patterned conductor 610 is a patterned conductor (patterned conductor for arranging light sources in one row) for forming a light source connected body in which light sources are arranged in one row as described above. It has a structure in which two are connected in the width direction. More specifically, the patterned conductors 6 10 for arranging the light sources 10 and 2 rows are composed of first to third trunk paths 6 1 1, 6 1 2, and 6. A pilot hole 6 14 for facilitating the positioning of the transport Z by the progressive press machine is formed in the central second trunk road 6 12. A plurality of light source mounting portions 6 15 are arranged in the longitudinal direction between the first main road portion 6 11 and the second main road portion 6 12, and each light source mounting portion 6 15 extends in the width direction. Corresponding to the first main road 611 and the second main road 612 by corresponding branch paths 6 16 and 6 17, and adjacent light source mounting sections 6 15 are mutually connected. Linked by 6 1 8 ing. Similarly, a plurality of light source mounting portions 6 25 are arranged in the longitudinal direction between the second trunk portion 6 12 and the third trunk portion 6 13, and are connected in the longitudinal direction by the communication path portion 628. At the same time, each light source mounting portion 6 25 is connected to the second trunk portion 6 12 and the third trunk portion 6 13 by the corresponding branch portions 6 26 and 6 27 extending in the width direction. Have been. In this embodiment, it can be said that the central second trunk section 6 12 is shared by two patterned conductors for arranging the light sources in a line. Each light source mounting portion 6 15 arranged between the first trunk portion 6 11 and the second trunk portion 6 12 is a pair of terminal connecting portions 6 1 corresponding to a pair of terminals of the corresponding light source. In this embodiment, each pair of terminal connecting portions 6 19, 6 19 are connected to each other by two bridge portions 6 19 A, 6 19 A, and a light source is connected. Previously, the bridge portions 6 19 A and 6 19 A are cut off, and the pair of terminal connection portions 6 19 and 6 19 in each light source mounting portion 6 15 are separated from each other. In addition, each terminal connection portion 619 is formed with a hole 620 for inserting a lead wire when the light source has the lead wire. Similarly, each light source mounting section 6 25 arranged between the second trunk section 6 11 and the third trunk section 6 13 has a pair of terminal connections corresponding to a pair of terminals of the corresponding light source. In this embodiment, each pair of terminal connecting portions 629 and 629 is connected to each other by two bridge portions 629A and 629A. In addition, each terminal connection portion 629 has a hole 630 for inserting a lead wire when the light source has the lead wire.

FIG. 63 b is a diagram showing an example of the secondary processing procedure of the patterned conductor 610 in FIG. 63 a. In this figure, the light source 635 and the resistor 636 to be attached are indicated by a dotted line, and a portion to be cut off is indicated by a diagonal line. The light source 635 and the resistor 636 may have leads similar to the LED 102 and the resistor 122 shown in FIG. 16, but a chip type without a lead wire. It may be. The polarity of the applied power supply voltage is indicated by a symbol. this In the example, the patterned conductors 6 10 are subjected to secondary processing so that each row of the light sources 6 3 5 forms a light source series-parallel body in which a plurality of series blocks each including 4 light sources 6 3 5 are connected in parallel. It will be understood that. Of course, it is also possible to subject the patterned conductors 6 10 to secondary processing so that the light sources 635 of each row are connected in series or in parallel.

FIG. 64 is a plan view showing an embodiment of a patterned conductor in which light sources can be arranged in four rows. This patterned conductor 640 has a configuration in which two patterned conductors shown in FIG. 63A are connected in the width direction. For example, as shown in the figure, a light source in each column is applied by applying a power supply voltage. It will be understood that it is possible to supply power properly. As described above, according to the present invention, a plurality of light sources can be arranged in a plurality of rows, and by changing the cut portions in the secondary processing, the light sources can be arranged in various modes such as parallel, series, and series-parallel in each row. A patterned conductor to which a light source can be coupled is provided.

Because LEDs have the advantages of low power consumption and long life, it has been proposed to use multiple LEDs as a light source to form a signal light, when LEDs are connected in series or series-parallel. If one LED breaks down and no longer conducts current, no current will flow through the LED connected in series with that LED, and the overall brightness of the signal light will drop significantly. It is known that a plurality of LEDs are connected in parallel, and a plurality of parallel-connected bodies are connected in series to form a matrix circuit (for example, FIG. 9 of Japanese Utility Model Application Laid-Open No. 4-8454). . In such a circuit, even if one LED fails and stops supplying current, current can flow through the LEDs connected in parallel with it, so that the light quantity does not decrease significantly. However, in such a circuit, if one LED experiences a short-circuit fault, both ends of each LED connected in parallel with that LED will be short-circuited, and these LEDs will Because no light is emitted, the amount of light is greatly increased Will drop. FIG. 65 is a schematic diagram showing an LED circuit suitable for a signal lamp that can prevent a large decrease in the total light quantity even in the case of such a LED short-circuit failure.

The LED circuit 650 in FIG. 65 is a matrix-shaped circuit in which eight light source parallel connected bodies 652 each consisting of five LEDs 651 connected in parallel are connected in series. Is similar to the conventional one, but is characterized in that each LED 651 has an associated resistor 653 connected in series. As a result, even if one LED 651 is short-circuited, a voltage is generated across the resistor 653 connected in series with the LED 651, so that the LED 651 Both ends of the other LED 651 connected in parallel are not short-circuited, and light emission is maintained. Therefore, even if a short-circuit failure of one LED 651 occurs, it is possible to prevent a large decrease in the total light quantity. The number of LEDs 651 connected in parallel and the number of parallel light sources 652 connected in series can be arbitrarily changed.

As shown in FIG. 66, a circuit configuration in which a plurality of light source parallel connected bodies 626 are connected in series and light sources 661 are connected in a matrix like the LED circuit 650 shown in FIG. 65 A separate LED circuit 660 is added and connected to independent power supplies (first and second power supplies), and the light sources 651 and 661 are almost overlapped. May be arranged to constitute the light emitting device 670. By using the two circuits 650 and 660 connected to the separate power supplies in this way, even if one of the power supplies fails, the minimum required brightness can be maintained.

As shown in FIG. 67, a light emitting device 670 having a circuit configuration as shown in FIG. 66 uses a light source connector 670 formed using a patterned conductor according to the present invention. It can be easily formed. The light emitter device 670 of FIG. 67 includes a plurality of light source connected bodies 671 arranged in the width direction, and is different. Light source connected bodies 671 connected to power supplies (first power supply and second power supply) are alternately arranged in the width direction. The LEDs included in each light source connected body 671 are connected in parallel with each other between a pair of trunk paths 672 and 673 extending in the longitudinal direction. Connected to 3. Such a connected light source can be easily formed, for example, by subjecting the patterned conductor 500 shown in FIG. 56 to secondary processing, cutting off a required portion, and connecting an LED as a light source. The light source assemblies 6 7 1 are connected by alternate jumpers — lines 6 7 6 and 6 7 6 to form two matrix-like LED circuits as shown in Figure 65, with light source connections located at both ends. The body 671 is connected to the first power source or the second power source. In this manner, a highly reliable surface light emitting device suitable for a signal light can be formed by using the light source connector 670 formed using a patterned conductor (such as 500).

FIG. 68 shows another embodiment of a light source combination according to the invention having a plurality of light sources electrically connected to one another in a matrix and spatially arranged in a row as shown in FIG. It is a typical partial top view showing an example. In this figure, the mounting direction of each LED is indicated by a symbol. This connected light source can also be formed by using a connection conductor structure formed by cutting off a required portion of the patterned conductor 500 shown in FIG. In this figure, the same parts as those in FIG. 56 are denoted by the same reference numerals, and detailed description is omitted.

This light source connected body 700 has a plurality of LEDs 701 as a plurality of light sources arranged in a line in the longitudinal direction, similarly to the above-described embodiment, and in this embodiment, each is connected in parallel. A plurality of light source parallel connected bodies including three LEDs 701 are connected in series. Of course, the number of LEDs 701 included in each parallel connection is not limited to three, and another number of LEDs 701 can be included. As in the above embodiment, the light source assembly 700 is also an LED 7 0 1 has first and second trunk roads 5 1 1 and 5 1 2 extending in the longitudinal direction, and each LED 701 is between these trunk roads 5 1 1 and 5 1 2 Are connected via a branch section 5 13 and a resistor 7202, but the directions of the LEDs 701 included in the adjacent parallel connection are reversed, and the first and second trunks are connected to each other. The difference from the above embodiment is that a part of the road sections 511 and 5112 is cut off. Thus, when a DC voltage is applied with the polarity as indicated by the symbol, a current generally flows from the left side to the right side of the figure. As can be understood from the figure, since the direction of the LED 701 included in the adjacent parallel-connected body is reversed, it is included in the upstream parallel-connected body among the adjacent parallel-connected bodies. The cathode of the LED 701 is connected to the anode of the LED 701 included in the downstream parallel connection body. In addition, the first and second trunk roads 5 1 1 and 5 1 2 are connected to the anode of the LED 701 included in the upstream parallel connection and the downstream parallel connection of the adjacent parallel connection. The LED 701 is disconnected between the adjacent parallel connections so that the power source of the LED 701 is separated from the LED 701 and the two ends of each LED 701 are not short-circuited (reference numerals 73, 7). 04). As described above, according to the present embodiment, the light emitting device has a circuit structure in which a parallel connection body including a plurality of light sources 7 01 connected in parallel is connected in series, and the light sources 7 0 1 are arranged in a straight line. A line emitter can be obtained.

Even in this light source connected body 700a, the power supply voltage is applied as indicated by the symbol, and the current generally flows from left to right in the figure. In this example, the LED 701 used as a light source has the same orientation, but the power sword of the LED 701 included in the upstream parallel connection among adjacent parallel connections (or connected to it). To connect one of the trunk roads 5 1 2) to the anode of LED 701 included in the downstream parallel connection (or the other trunk road 5 1 1 connected to it). Two The light source mounting portion 5 15 (or the terminal connection portion 5 19 included therein) and the branch portions 5 13 and 514 for connecting them to the trunk portions 5 11 and 5 12 are used. For this reason, this embodiment has a disadvantage that the distance between adjacent parallel-connected bodies is larger than that of the embodiment shown in FIG.

As a result, when the ridge portion 52 1 A located between adjacent light source parallel connection bodies is cut to form a connection conductor structure for connecting the LED as a light source, the central portion and the branch portions 5 17, 5 5 By leaving LED 18 as shown in Fig. 71, when LED 701 as the light source is assembled, the LED 7 included in the electrically upstream side of the adjacent parallel connection of light sources is installed. It is possible to communicate the power source of 01 and the anode of LED 701 contained in the downstream one.

As a result, when the other illuminant devices 710a having the same structure are connected in the axial direction, the power supply voltage is applied to the other illuminant devices 7l7, 7l8 and the conductive pins 7l5, 7l5. It can be easily supplied to the luminous device 7110a. One of the pair of output terminals of the diode bridge 7 16 (in this example, the high voltage side) is connected to the anode of the LED 7 0 1 of the light source parallel connected body located on the most upstream side in the light source connected body 700 b. The other side (the low-voltage side in this example) is connected via the crossover 7 19 to the LED 7 0 of the electrically downstreammost light source parallel connection in the light source connection 7 00 b. 1 force connected to the sword side.

As a result, the crossovers 717, 718, 719 can be held at predetermined positions in the glass tube 711.

FIG. 73 shows a light source assembly having a plurality of light sources electrically connected to each other in a matrix as shown in FIG. 65 and spatially arranged in a line. FIG. 21 is a partial plan view showing another secondary processing method of the patterned conductor 500 shown in FIG. In FIG. 73, the same parts as those in FIG. 56 are denoted by the same reference numerals, and detailed description will be omitted. Also, in this figure, the portion to be cut is indicated by oblique lines. Figure 74 is patterned as shown in Figure 73. FIG. 4 is a partial plan view of a light source connection body formed using a connection conductor structure formed by secondary processing of a conductor. In this figure, the LED 701 is schematically shown so that the connection direction can be understood.

As shown in FIGS. 73 and 74, in this embodiment, the LED 701 is connected in parallel between the first main road 511 and the second main road 512. At this time, the entire bridge 5 21 A is cut off. Further, similarly to the above-described embodiment, the first and second trunk roads 5 11 1 and 5 12 are cut at a position substantially between the adjacent light source parallel connection bodies.

In the embodiment of FIG. 73, the branch sections 5 13 and 5 14 are left uncut, and these branch sections 5 13 and 5 14 are the first and second trunk sections 5 1 1 , 512 are bent at the positions indicated by arrows C and D such that the main surfaces of the communication paths 5110 are substantially perpendicular to the main surfaces. Arrows A and B are shown so that the free ends 511A and 512A formed by cutting the first and second trunk roads 511 and 512 are in contact with each other. In this position, the trunk roads 5 11 and 5 12 are bent toward the center, and the free ends 5 11 A and 512 A that have come into contact with each other are connected, for example, by welding to form a conductive path (FIG. 74). ). As shown in FIG. 74, when the LEDs 701 as light sources are all mounted in the light source mounting portions 5 15 corresponding to the same direction, the conductive paths electrically connect the adjacent light source parallel connection bodies. The power source of LED701 included in the upstream one (left side in the figure) and the anode of the LED701 included in the downstream one (right side in the figure) are connected to connect the light source parallel connection. They can be connected in series. In addition, by cutting the first and second trunk roads 5 1 1 and 5 1 2 at appropriate places, the LED 7 included in the electrically upstream side of the adjacent light source parallel-connected body is connected. The node of 01 and the cathode of the LED 701 included in the downstream device are separated from each other, and a short circuit at both ends of each LED 701 is prevented. In the embodiment shown in FIGS. 73 and 74, the branch portions 5 13 and 5 14 are all However, it is also possible to cut out part or all and use a resistor having a lead wire instead.

Fig. 75 shows a light source assembly in which the light sources are connected in a matrix and formed using patterned conductors 61 suitable for arranging the light sources in two rows as shown in Fig. 63a. FIG. 4 is a schematic partial plan view showing In this figure, the same parts as those in FIG. The LEDs are indicated by symbols to indicate the connection direction. In FIG. 75, the patterned conductor 6 10 is shown as having already been cut off (ie, as a connecting conductor structure). Each LED 7 21 is connected between the first trunk 6 1 1 and the second trunk 6 1 2 via the corresponding branch 6 1 6 and 6 26 and the resistor 7 22 or It is connected between the trunk road section 6 12 and the third trunk road section 6 13. Further, in each of the two rows of LEDs 721, a plurality of light source parallel connected bodies each formed by connecting three LEDs 721 in parallel are formed, and as shown by the symbol in the figure, adjacent parallel connected light sources are formed. The LED 721 included in the connector has the opposite orientation. In addition, a part of the first to third trunk roads 6 11 1 to 6 13 is cut off (reference numerals 72 3, 724, and 7 25). As a result, each column of the LEDs 721 forms a matrix-like circuit, and when a voltage is applied with the polarity shown by the symbol, the current also flows from the left to the right in the circuit in this circuit as well. FIG. 76 is a schematic view showing a preferred embodiment in which a surface light emitting device is formed using a plurality of light source connected bodies formed according to the present invention. In this example, a red light source combination 732 including multiple red LEDs (R), a green light source combination 732 including multiple green LEDs (G), and multiple blue LEDs (B) are connected. The surface light emitting device 730 having a circular light emitting surface is formed by using the blue light source connected body 733 that includes the light emitting device. As shown in the figure, these three light source connected bodies 731, 732, and 733 are separated from their starting points RS, GS, and BS, which are substantially equally spaced circumferentially at the periphery of the light emitting surface. Swirl towards the center It is arranged so as to form. This makes it possible to emit light of each color in a substantially circular shape at the same brightness. FIG. 77 shows an embodiment in which a square surface light emitting device 730a is formed by using the same method. The shape of the surface light emitting body thus formed can be arbitrarily selected. Further, in the above embodiment, one light source connected body is used for each color. It is also possible to arrange. It is also possible to use not only three colors but also light sources (LEDs) of two colors or more than three colors. Of course, it is also possible to make the emission colors of the light sources included in all the light source connected bodies the same.

FIG. 78 is a schematic view showing another embodiment in which a surface light emitting device is formed using a plurality of light source connected bodies formed according to the present invention. As shown in the figure, in the surface emitting device 7400, a plurality of red, blue, and green light source connected bodies are concentrically arranged. It will be understood that such an arrangement is not limited to a circular shape, as in the above embodiment.

FIG. 79 is a schematic view showing a usage example of the light source assembly (for example, the light source assembly 101 shown in FIG. 36) according to the present invention. In this figure, the details of the connection conductor structure 104 are not shown. Since the light source assembly according to the present invention has flexibility, it can be used by being twisted as shown in the figure. Thus, the light sources 102 are arranged in a substantially spiral shape, and it is possible to illuminate the surrounding space substantially uniformly.

By the way, LEDs have a much longer life than incandescent lamps, etc. . Such an in-vehicle lamp, for example, when provided at a corner of a vehicle body, must have a three-dimensional structure to match the overall shape of the vehicle body. Therefore, the LED as a light source must be three-dimensionally arranged accordingly.

Such an in-vehicle lamp in which LEDs are arranged three-dimensionally is disclosed in, for example, Japanese Patent Application Laid-Open No. H11-121807. The on-vehicle lamp disclosed in this publication includes a plurality of LEDs, a base having a plurality of steps having a step shape, a holder fitted and supported by the plurality of steps, and holding a corresponding LED. And a light emitting unit having a light emitting unit, which is housed in a lamp chamber defined by the lens and the lamp pod. An electrical cord is sandwiched between the LED and the holder, thereby making an electrical connection for the LED. Each LED lead is provided with a slit with a width roughly corresponding to the diameter of the core so that the electric cord can be peeled off and the core of the electric cord exposed when the LED is mounted on the holder. Have been. Further, each holder is provided with an electric cord passage for temporarily holding an electric cord before mounting the LED.

In such a vehicle-mounted lamp, after the holder is attached to the base, the electric cord is passed through the through groove of the holder, then the LED is inserted into the holder, and the electric cord is sandwiched between the LED and the holder. Thus, a light-emitting unit, which is a main component of the lamp, can be formed. As another method, utilizing the fact that the holder is separate from the base, first hold the electric cord and LED in the holder to form a light source assembly, and then attach the holder to the base. By doing so, a light emitting unit can be formed.

However, such an in-vehicle lamp has a problem that the number of parts is increased and the management cost and the manufacturing cost are increased because the holder is separate from the base. If the holder is integrated with the base, the shape of the base will be complicated and the mold cost of the base will rise. Also, in any of the assembly processes described above, the electrical cords must be Automation is extremely difficult because of the need to pass Furthermore, the use of LEDs with specially shaped leads and the inability to use commercial products have also contributed to increased manufacturing costs.

FIG. 80 is a perspective view of an embodiment of a light-emitting device for a vehicle-mounted lamp using a light source connected body according to the present invention in order to solve the above-described problem. As shown in the figure, the luminous device 800 has a plurality of (in this example, nine) LEDs 802 as light sources, and has a stepped shape to arrange these LEDs 802 three-dimensionally. A base (holding body) 830 having a plurality of steps. Such a luminous body device 800 is housed in a lamp chamber defined by a housing (not shown) constituting a part of a vehicle body and a lens (not shown) attached to the housing, as in the prior art. Used as In this embodiment, each LED 802 has a plate-shaped anode terminal 803a and a force source terminal 803b.

In this embodiment, three LEDs 802 are connected in parallel to form one light source combination 811, and three such light source combinations 8001 are connected in series with three jumper members 815. They are connected to form a so-called matrix circuit (or parallel-series circuit). In this example, the adjacent light source connected bodies 801 are connected by one jumper member 815 at their ends. However, in order to reduce electric resistance, improve heat transfer characteristics, etc. The connection may be made by two or more jumper members 8 15, and the number is arbitrary. In addition, in the illustrated example, the jumper member 815 is formed by bending a plate-shaped conductor at an appropriate position, but a covered conductor or the like may be used. FIG. 81 is a perspective view showing the light source connected body 811 before bending to conform to the shape of the base 830, and FIG. 82 is an end view thereof. As shown in the figure, the light source connector 801 has a connecting conductor structure 804 for electrically connecting a plurality of (three in this example) LEDs 802. Connection conductor structure 804 has a pair of conductors (trunk portions) 811 and 812 extending substantially parallel to the longitudinal direction, and has an anode terminal 80.3a and a cathode terminal 800 of each LED802. 3b is attached to the corresponding trunk roads 811 and 812, preferably by welding such as laser welding. That is, in this embodiment, it can be said that the pair of trunk roads 811 and 812 includes the light source mounting portion (or the light source terminal connection portion).

In this embodiment, the width of the trunk section 8 1 2 to which the power sword terminal 8 0 3 b of each LED 802 is attached is wider than the trunk path 8 1 1 to which the anode terminal 8 0 3 a is attached, It is easier to conduct heat. Usually, in each LED 802, the LED chip (not shown) sealed in the LED package is directly mounted on the plate-shaped cathode terminal 803b, and the anode terminal 803a and Are connected by a lead wire, etc., and most of the heat generated from the LED chip is released to the outside via the force source terminal 803b. By making the connected trunk section 812 wider, heat from the LED 802 can be more efficiently dissipated. Further, by narrowing the width of the main road section 8111 to which the anode terminal 803a that contributes little to heat radiation is connected, the width of the light source connected body 801 can be reduced.

Like the above-described embodiment, such a light source connected body 8001 is attached to a tape-shaped patterned conductor having a predetermined pattern at an appropriate position, and then the LED 802 is attached to the patterned conductor. It is obtained by cutting out the required portion to form a connection conductor structure 804 that connects the LEDs 802 in parallel. FIG. 83 is a partial plan view of one embodiment of a patterned conductor suitable for forming such a light source connected body 81 having the LEDs 802 connected in parallel. As shown in the figure, the patterned conductor 8 20 has a flat tape shape, and a pair of conductors (trunk portions) 8 11 and 8 1 2 extending in the longitudinal direction. There are a plurality of branch sections 813 connecting the trunk sections 811 and 812 in the width direction. As described above, the trunk section 8 1 2 to which the power source terminal 8 0 3 b of the LED 8 0 2 is attached is wider than the trunk section 8 11 1 to which the anode terminal 8 0 3 a is attached. . Also, a plurality of pilot holes 818 that can be used for conveyance / positioning by a progressive press machine (not shown) or the like are provided at predetermined intervals in the longitudinal direction in each trunk road section 811 and 812. It is provided.

After mounting the LED 802 between the pair of trunk roads 8 11 1 and 8 1 2 of the integrated conductor 8 20 by laser welding, for example, the pair of trunk roads 8 1 1 and 8 1 2 By cutting off the branch portions 8 13 connecting between them and further cutting the patterned conductors 8 20 to an appropriate length, the light source assembly 8 having an arbitrary number of parallel-connected LEDs 8 02 0 1 can be formed. Before mounting the LED 802, the pair of trunk roads 811 and 812 are mechanically connected by the branch road 813, so that the patterned conductor 8200 can be easily handled. Yes, this allows the LED 802 to be attached to the patterned conductor 820 as described above, the branch 813 of the patterned conductor 820 to be cut off, and the trunk 811, 81 The work such as cutting can be automated on one production line including a progressive press machine to improve production efficiency. In addition, by attaching the LED 802 to the patterned conductor 820 by laser welding without using a special holder, the number of parts and the management cost can be reduced.

The light source connected body 811, as shown in FIG. 81, formed in this manner is bent at a predetermined position and attached to the base 83, so that the light-emitting body for a vehicle-mounted lamp as shown in FIG. A device 800 can be formed. To attach the light source connector 801 to the base 830, for example, a boss (not shown) is formed at a predetermined position of the base 830, and the light source is connected to these bosses. This can be achieved by fitting pilot holes 818 provided in trunk sections 811 and 812 of body 801 or by using an adhesive. When attaching the light source assembly 801 to the base 830, it is desirable that each LED 802 be placed at an appropriate position on the base 830. If the bending accuracy is low, the position may not be appropriate. In such a case, it is desirable that the position of the LED 802 can be adjusted so that each LED 802 is arranged at an appropriate position. In the above example, the LEDs 802 included in the respective light source connected bodies 81 are arranged in a straight line. However, it is desirable that the arrangement direction of the LEDs 802 be offset or bent. In some cases. FIG. 84a is a partial plan view illustrating another embodiment of a patterned conductor that enables such adjustment of the LED position. Further, FIG. 84b is a view similar to FIG. 84a, in which a portion to be cut off in a use state is illustrated by hatching.

Preferably, the extendable portion 8221 is formed between adjacent LED mounting locations. Although the width of the pair of trunk roads 811 and 812 is the same in FIG. 84a, it is of course possible to have different widths as in the embodiment shown in FIG. 83. It is.

In the embodiment of FIGS.84a and 84b, each telescoping portion 821 includes a pair of generally U-shaped narrow connecting channels 822 formed in each trunk portion 811, 812, The pair of straight portions facing each other of the U-shaped connection path 8 2 2 extend in the width direction of the main road sections 8 1 1 and 8 1 2, and the bent bottom portion is located on the center axis side of the patterned conductor 82 0 ′ are doing. The extendable portion 8 2 1 is It has a ridge portion 823 extending in the longitudinal direction at the widthwise ends of the trunk road portions 811 and 812 so as to connect both ends of the U-shaped connection passage 8222, whereby Normally, the deformation of the extensible portion 8 21 is prevented, and the bridge portion 8 23 functions as a deformation preventing portion. At the time of use, as shown by hatching in FIG. 84b, the desired extensible portion 8221 can be deformed by cutting off the bridge portion 823. By using the ridge portion 823 in this way, it is possible to selectively deform the expandable and contractible portion 821 only at the necessary portion so that the LED arrangement position can be adjusted. Unnecessary reduction in strength can be prevented. In addition, before the bridge portion 82 is cut off, the patterned conductors 82 0 ′ or the light source connected body formed using the same are relatively rigid, so that they can be easily handled. is there. The stretchable portion 821 and the bridge portion 823 of the patterned conductor 820 'can be formed easily and inexpensively preferably by stamping by press working.

In FIG. 85a, the arrangement direction of the LEDs 802 (or the longitudinal axis of the light source assembly 801 ′) is changed by the deformation of the stretchable portions 8 2 1 at two places in the longitudinal direction. It is bent in a plane parallel to the main surface of 0 '(or the connecting conductor structure 8004), and as a result, the arrangement direction of the LEDs 802 is offset in the width direction (lateral direction) at the right and left ends of the figure. ing. In FIG. 85, the extendable portion 8 21 is deformed such that the distance between adjacent LEDs 8 0 2 extends in the longitudinal direction of the light source assembly 8 0 1 ′. As described above, in the light source connected body 8 0 1 ′ using the patterned conductor 8 20 ′ having the extendable portion 8 2 1, the arrangement position of the LED 8 0 2 is adjusted so that the LED 8 2 Not only can you place it in the right place, but also various LED arrangements Therefore, the degree of freedom in designing the shape of the vehicle-mounted lamp can be greatly improved. Alternatively, the same light source connector 8 0 1 ′ can be used for different bases as long as the difference can be absorbed by the deformation of the extendable portion 8 2 1 of the light source connector 8 0 1 ′. is there.
