Description

LIGHT SOURCE COUPLER, ILLUMINANT DEVICE, PATTERNED CONDUCTOR, AND METHOD FOR MANUFCTURING LIGHT SOURCE COUPLER}

BACKGROUND ART A light emitting device having a structure in which a plurality of light sources are arranged on the surface of a holder is used for applications such as advertisement, decoration, display, etc. in addition to simple lighting. In order to form this kind of light emitting device, for example, a shell type LED light source having a lead wire, a through hole into which the lead wire of the light source is fitted, and a printed circuit board on which a conductor pattern for feeding power to the light source are formed are used. The connection between the conductor pattern of the printed board and the lead wire of the light source can be considered by flow soldering.

By the way, in the case where the printed circuit board is used for the holder of the light source, a cost advantage can be obtained when manufacturing in large quantities. However, when a small amount of a large variety of products having different light source connection patterns or arrangements is produced, the cost is rather high. There is a fear that this will rise. In addition, since the printed circuit board is exposed to high temperature by contact with molten solder at the time of soldering, it is not preferable for heat-weak LEDs. In general, solder contains lead, and its use requires environmental measures. The use of lead-free solder can also be considered, but since the cost is high and the melting point is higher than that of ordinary solder, the influence of heat on the LED is further problematic. Moreover, with a printed board, it is difficult to cope with the case where a light source is arranged on a curved surface. When the structure which connects a light source through a flexible lead wire takes time for connecting a wire, cost may increase. In addition, since the printed circuit board is integrated with the support plate, there is a problem that recycling when it becomes unnecessary is extremely difficult.

As a light emitting module that does not use a printed circuit board and solder, JP-A-7-106634 discloses that a plurality of LEDs are connected by mechanically engaged connection between an anode bus bar and a cathode bus bar. Japanese Patent Laid-Open No. 8-316531 also includes a plurality of busbar pairs, a plurality of LEDs mounted on each busbar pair, and a flexible joint for electrically and mechanically coupling between adjacent busbar pairs. Disclosed is a light emitting module that facilitates the operation. However, in the inventions disclosed in these publications, there is no disclosure about a light source connector and a method of manufacturing the same that can easily select various light source connection patterns and can be manufactured with high production efficiency.

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

The present invention has been made to solve the problems of the prior art as described above, the main object of the present invention is a light source connector having a plurality of light sources that can be manufactured efficiently and at low cost without using a printed board and a method of manufacturing the same To provide.

It is a second object of the present invention to provide a light source connector and a method of manufacturing the same, which can eliminate the use of solder or significantly reduce the amount of use.

It is a third object of the present invention to provide a light source connector and a method of manufacturing the same that can easily cope with various arrangements of light sources.

A fourth object of the present invention is to provide a light source connector as described above using a chip type LED as a light source and a method of manufacturing the same.

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

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

In order to achieve the above object, according to an aspect of the present invention, a light source connector formed by electrically connecting a plurality of light sources, the light source connector is extended in the array direction of the light source to connect the plurality of light sources A light source connecting body is provided, which comprises a connecting conductor structure, wherein the connecting conductor structure is formed by cutting out a portion of a required patterning conductor which is a substantially flat plate on which a predetermined pattern is formed. The patterned conductor can be formed by pressing a conductive plate material. According to this, since the light source connector can be formed without using the printed board, the solder used for the connection with the printed board can be eliminated, and there is no need to worry about environmental pollution. There is no need to worry about LED damage. Also, by changing the cutout of the patterned conductors, it is possible to form a connection conductor structure having various light source connection patterns in one manufacturing line using the same patterned conductors. Even small quantities can be produced efficiently and at low cost. In addition, when the patterned conductor is formed of a conductive flat plate material, by providing appropriate flexibility, the light source connecting body can be appropriately deformed into a desired shape, and it can easily cope with various arrangements of the light source. Moreover, since the printed board is not used, it is easy to recycle when it is no longer needed. In addition, when the patterned conductor has a long tape shape, it is preferable because the light source connector can be continuously produced by carrying out a process such as attaching a light source, pressing, or the like while conveying it to a production line. It is also possible to obtain a light source connector of a desired length by cutting the patterned conductor to an appropriate length.

According to one embodiment of the present invention, the plurality of light sources includes a chip-shaped LED, and a socket for mounting the chip-shaped LED is attached to the connection conductor structure by an insert mold. Typically, the socket has a bottom wall and sidewalls to define a cavity with an opening on top, and the chipped LED is housed in this cavity. By doing this, even when a chip type LED having no lead wire is used as the light source, the chip type LED can be easily attached to the connection conductor structure to obtain a light source connector.

Preferably, a hole is formed in the bottom wall of the socket, and the LED mounted on the socket can be pressed therein to remove the LED from the socket. In this way, the failed LED can be quickly replaced with the normal LED. In addition, it is preferable to realize a quick mounting of the LED into the socket by exposing a part of the connection conductor structure in the cavity of the socket and making contact with the electrical terminal of the chip LED with the chip LED mounted on the socket. . More preferably, the part exposed in the hole of the socket of the connection conductor structure has a projection for contacting the electric terminal of the LED. By doing so, the electrical connection between the LED and the connecting conductor can be made more secure. In addition, if a part of the connecting conductor structure is bent and engaged with the LED mounted on the socket to prevent the LED from falling out of the socket, the LED does not fall undesirably even when the light source connector is attached upside down. It is preferable because of that.

In another embodiment of the present invention, the chip-shaped LED is a side view type having a light emitting portion at the side, 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. By doing this, it is also possible to use side view type LEDs.

According to another embodiment of the present invention, the plurality of light sources includes a light source having lead wires, and the connection conductor structure has holes corresponding to the lead wires of these light sources. It is preferable that the part which defines the hole of a connection conductor structure includes the protrusion part which protrudes toward the inside of this hole. Typically, the lead wire of the light source is inserted into the hole of the connection conductor structure, thereby making electrical / mechanical connection between the light source and the connection conductor structure. Further, if the lead wire of the light source is caulked by the portion of the connection conductor structure close to the hole of the connection conductor structure, and thus the light source is held, it is further preferable in that it prevents the dropping of the unwanted light source. 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 still another embodiment of the present invention, each of the plurality of light sources includes a pair of lead wires extending substantially parallel to each other, and the plurality of light sources are arranged in a direction substantially perpendicular to the lead wires, and the connecting conductor structure. Is arranged so that its main surface extends along the lead wires substantially, and is joined to these lead wires to connect the light sources. In this case, the patterned conductor forms a tape shape of the apparatus and has a plurality of connections to the lead wires of the light source, and these connections are arranged side by side corresponding to the arrangement of the plurality of light sources held by the radial taping. desirable. According to this, when joining a light source and a patterned conductor, since a some light source can work in the state hold | maintained integrally by radial taping, workability can be improved. After attaching the light source to the patterned conductor, the lead wire is cut at a predetermined position, and the required portion of the patterned conductor is cut out to form a connection conductor structure to obtain a light source connecting body. Moreover, what is necessary is just to bend the cross-sectional shape which appears when it cuts to the plane perpendicular | vertical to the longitudinal direction of a connection conductor structure. Accordingly, even in a simple configuration in which the connection conductor structure is not covered with an insulating material and exposed, it is possible to prevent unwanted contact between the connection conductor structure and the lead wires and to avoid an unintended short circuit in the circuit. By exposing the connection conductor structure without covering it with an insulating material, the heat dissipation effect by the connection conductor structure becomes high, and the advantage that it can respond suitably also when the light source is arrange | positioned at high density can also be acquired. Moreover, since curvature of a longitudinal direction is regulated, the workability at the time of sticking to a holding body can be improved.

The patterned conductor preferably has a tape shape of a long dimension, and further includes a plurality of light source attachment portions arranged in the longitudinal direction for electrical connection with the light source, a communication path portion for communicating these light source attachment portions in the longitudinal direction, At least one path part spaced apart from the communication path part and the light source attachment part in the width direction and extended in the longitudinal direction, and a plurality of branch path parts which connect the path part and the communication path part in the width direction. Have In this way, the connection conductor structure which can connect a light source in various connection patterns by cutting out the predetermined part of a branch part, a communication path part, or an trunk path part can be formed. In addition, in the light source connector having the connection conductor structure formed in this way, the trunk portion can be used to connect the light source to the power source, and in this case, there is also an advantage that there is no need to provide wiring separately. In the case where a part of the trunk portion of the patterned conductor is cut off so that the connection conductor structure connects the light sources in series, if the uncut portion of the trunk portion is kept connected to the corresponding light source attachment portion through the corresponding branch portion, Since the negatively-unrestricted portion acts as a heat dissipation unit for dissipating heat generated from the light source, the excessive increase in the ambient temperature of the light source can be prevented.

In a light source connector formed using such a patterned conductor, a resistor can be connected between at least one pair of adjacent light sources, and the contact path portion can be divided between a pair of adjacent light sources connected between the resistors. . By doing this, for example, it is possible to connect a resistance to the light source to prevent the overvoltage from being applied to the light source.

More preferably, the light source connector further has a connecting member which extends in the width direction of the connecting conductor structure to hold the communication path portion and the trunk path portion integrally. In this way, when the required portion of the patterned conductor is cut off to form the connection conductor structure, it is possible to prevent each part of the connection conductor structure from scattering and to increase the mechanical strength of the formed connection conductor structure. Such a connecting member can be preferably formed by an insert mold. When the connecting member is formed by the insert mold, when the widthwise recessed portion or through hole is formed in the trunk path, and the connecting member extends through the widthwise recessed or through hole, the engagement of the connection member and the trunk portion is achieved. It is preferable because it can harden. Moreover, it is preferable that the hole which exposes the communication path part is formed in the position which matches with the communication path part of a connection member, and it is possible to segment the communication path part exposed through this hole. By doing so, it is possible to form a connecting conductor structure having a desired light source connection pattern by dividing the contact path portion after forming the connecting member. The part of the communication path portion exposed by the hole of the connecting member may have a width smaller than that of the other parts of the communication path portion so as to facilitate cutting. In addition, the connecting member may include one or a plurality of insulating sheets. The insulating sheet may be a plurality of insulating sheets extending in the width direction of the connecting conductor structure at a predetermined place, or one insulating sheet extending over almost the entire length of the connecting conductor structure. Thus, by using the insulating sheet, it is possible to miniaturize (thin) the light source connector manufactured as compared with the case where the connecting member is formed by the insert mold. If the insulating sheet is attached to the light source attaching surface of the connecting conductor structure, the part to which the power supply voltage is applied is not exposed to the light source attaching surface side which is relatively easy for the operator to contact, and thus the safety sheet can be improved, and the insulating sheet is removed from the light source. The light efficiency can be improved by reflecting light.

When the light source connector does not have a connecting member by an insert mold, or when such a connecting member is removed after attaching a light source to the connecting conductor structure or the like, such that the main surface of the trunk portion is substantially orthogonal to the main surface of the communication path portion. It is also possible to bend the branch to connect the contact with the contact. In this way, the light source connector can be easily attached to the holder by inserting the trunk portion into the matching recesses or holes formed in the holder.

Instead of, or in addition to using, the connecting member, a socket for mounting the chip-shaped LED may be extended in the width direction of the connecting conductor structure so as to hold the communication path portion and the trunk portion integrally.

When the plurality of light sources includes a chip type LED, the light source attachment portion corresponding to the chip type LED has a terminal connection portion corresponding to the terminal of the chip LED, at least one of these terminal connection portions has a directing portion, and the directing portion is bent to form a chip type LED. It can be a wall for positioning or maintenance. Preferably, the terminal connection portion of the light source attachment portion corresponding to the chip type LED has a pair of directing portions facing each other. By doing so, the socket formed by the insert mold or the like can be eliminated.

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 distance between the light sources can be changed to flexible. This means that, for example, when the light sources are connected in series or in parallel, the terminal connection parts included in each light source attachment part are connected when forming the patterned conductors (that is, during the primary processing). This can be achieved by separating the terminal connection portion only at the light source attachment portion to which the light source is attached during the machining.

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 connector. In this case, when the light source connector is bent in the longitudinal direction, the force for separating the terminal of the light source from the connection conductor structure does not work, so that the separation of the unwanted light source from the connection conductor structure can be prevented. Preferably, the light source attachment portion to which the light source having a pair of terminals is attached 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. Is realized.

Furthermore, when each light source has a pair of terminals, it is preferable that the patterned conductor has a pattern that can be used for serially, parallelly or in series parallel connection of the light sources. By doing so, even when the light source is connected anywhere in series, in parallel or in parallel, the light source connecting body can be formed of the same patterned conductor, so that the production efficiency can be improved and the manufacturing cost can be reduced. According to a preferred embodiment of the present invention, the patterned conductor has a long tape shape, and further includes a plurality of light source attachment portions arranged in the longitudinal direction for electrical connection with the light source, and the light source attachment portions in contact with the longitudinal direction. And a pair of trunk paths arranged on both sides by sandwiching the communication path portion and the light source attachment portion in the width direction and extending in the longitudinal direction, and a plurality of branch path portions that communicate with the trunk path portion and the communication path portion in the width direction. This structure makes it possible to easily and efficiently manufacture a connection conductor structure having various light source connection patterns from a common patterned conductor by cutting off portions of the required branch portion, the communication passage portion or the trunk portion. Therefore, even in small quantity production, manufacturing cost can be held down. Preferably, each of the light source attachment portions has a pair of terminal connection portions corresponding to a pair of terminals of the light source, and the communication path portion includes a plurality of connection paths connecting the terminal connection portions included in the adjacent light source attachment portions to each other. Include.

When the plurality of light sources include two different color LED chips and a three-pole LED lamp with three terminals, the patterned conductors form a tape of long dimension, and also for electrical connection with the light source. A plurality of light source attachment portions arranged in the longitudinal direction, a communication path portion for communicating the light source attachment portion in the longitudinal direction, and a pair of paths arranged on both sides by sandwiching the communication path portion and the light source attachment portion in the width direction and extending in the longitudinal direction; Section and a plurality of branch sections for contacting the trunk section and the contact section in the width direction, each of the light source attachment sections having three terminal connections arranged in the width direction corresponding to three terminals of the three-pole LED lamp. The part may be configured to include a plurality of connection paths connecting the terminal connection parts matched in the width direction of the adjacent light source attachment part to each other. By doing in this way, the light source connection body which used the 3-pole LED lamp as a light source can be implement | achieved, and light emission color can be changed in various ways by connecting a suitable power supply and a switch.

The plurality of light sources comprise a four-pole LED lamp comprising first and second LED chips of different colors and having four terminals, two of the four terminals being connected to the first LED chip.

These connection parts 9 are connected by the communication path part 10 which extends in the longitudinal direction, and this contact part 10 and the connection part 9 are inserted in the width direction (up-down direction of drawing), and the 1st and 1st The two trunk portions 11 and 12 are arranged on both sides of the tape-shaped patterned conductor 16. Moreover, the 1st and 2nd trunk path parts 11 and 12 and the communication path part 10 are connected by the some branch part 13 and 14 in the width direction.

The tape-shaped patterned conductor 16 becomes a connecting conductor structure 4 having a circuit of a predetermined connection pattern by performing secondary processing to cut out required portions as described above, but this secondary processing When the light source 1 and the tape-shaped patterned conductor 16 held by the radial taping can be bonded together by a sequential transfer press, it is preferable because the manufacturing process can be simplified. Therefore, in the tape-shaped patterned conductor 16 shown in FIG. 4A, the light source 1 and the tape-shaped patterned conductor 16 are formed so that the light source 1 can be properly bonded to a predetermined position of the tape-shaped patterned conductor 16. In order to align the position, the pilot hole 18 is engaged with the pilot pin of the sequential feed press (not shown) in the second trunk path portion 12 on the side opposite to the light source body portion 1a. . As another method, like the tapered patterned conductor 16 'shown in Fig. 4B, the edge plate portion 19 connected to the second trunk path portion 12 via the connecting portion 20 is provided, and thereafter, a sequential transfer press machine is provided. Although the pilot hole 18 may be formed to be engaged with the pilot pin, the material is required as much as the edge plate portion 19 as compared with the case of Fig. 4A.

Tape-shaped patterned conductor 16 can be obtained by press working (more specifically, punching processing) of a conductive flat plate material. Specifically, at the same time, the connecting portion 9 is formed so as to protrude from the communication path portion 10 in the direction along the lead wire 3, and at the same time, the communication path portion 10 and the first trunk path portion 11 are partitioned. The cutout hole 21 which defines the branch part 13 which connects them is formed. This cutting hole 21 ensures a space into which the tool for caulking the connecting portion 9 is inserted. In addition, a cutout portion 15 is formed in the first trunk portion 11. Further, a cutout hole 22 defining the branch portion 14 which connects the communication passage portion 10 and the second trunk portion 12 and connects them is formed. The branch portions 13 and 14 connecting the first and second trunk portions 11 and 12 to the communication path portion 10 are positioned at positions displaced from the lead wire 3 so as not to cut the lead wire 3 at the time of ablation. It is preferable to form. Thereby, the lead wire 3 is projected toward the appropriate length attachment board 2 side, for example, and is attached to the attachment board 2 when attaching the completed light source connector 6 to the attachment board 2. It can be inserted into the hole 7 to stabilize the installation (see Fig. 1).

Since the tape-shaped patterned conductor 16 has flexibility and is free to bend, it can be wound or coiled into a coil shape and can be easily stored, transported and packed.

FIG. 5 shows a situation in the manufacturing process of the light emitting device shown in FIG. 1. The light source 1 is a shell type LED lamp in which a pair of lead wires 3 are drawn in the same direction, and are arranged side by side in a direction orthogonal to the lead wires 3 by radial taping. The carrier tape 25 for radial taping is composed of a pair of tape materials 25a and 25b that can be joined together, and the light source 1 is sandwiched by sandwiching the lead wires 3 between the two tape materials 25a and 25b. ) Is fixed. A pilot hole 26 is formed in the carrier tape 25 similarly to the tape patterned conductor 16, and the pilot holes 18 and 26 of the tape patterned conductor 16 and the carrier tape 25 are matched. By doing so, the axial position of the connection part 9 formed in the tape-shaped patterned conductor 16 and the lead wire 3 of the light source 1 hold | maintained by the carrier tape 25 is matched. In this way, the connection part 9 is attached to the lead wire 3 in the state hold | maintained by the tape 25, and the secondary processing of the tape-shaped patterned conductor 16 is performed. On the other hand, when the lead wire 3 and the connecting portion 9 are attached to each other, the tape-shaped pattern does not interfere with the main body portion 1a of the light source 1 and the first path portion 11 of the tape-shaped patterned conductor 16. The conductor 16 must be bent along a longitudinal bend line.

As described above, the connection between the tape-shaped patterned conductor 16 and the light source 1 is performed by preparing the tape-shaped patterned conductor 16 wound in a coil shape and unwinding it in a sequential transfer press. It is preferable at the point of ease of handling. As described above, the tape-shaped patterned conductor 16 according to the present invention is provided with a cutout portion 15 in the width direction in the first trunk path portion 11, so that the first trunk path portion 11 has a plurality of convex curved portions. Therefore, even if the coil is wound in a coil shape, only the convex curved portion of the unwound portion can be bent separately for the mounting of the lead wire 3 of the light source 1, so that the main body portion of the light source 1 ( It is possible to prevent interference between 1a) and the first trunk portion 11 of the tape-shaped patterned conductor 16.

FIG. 6 is a diagram illustrating the second processing of the tape-shaped patterned conductor 16 for the series-parallel light emitting device shown in FIG. 1. In this figure, an ablation part is shown with the oblique line. As shown, the portion 27 of the communication path portion 10 between the pair of connecting portions 9 to which the lead lines 3 of the same light source 1 are coupled is cut off. And the branch portions 13, 14 except for the branch portions 13, 14 positioned at the end of the range (serial block) to which the light source 1 is connected in series are cut off, and at the same time, the contact connecting the adjacent series blocks. The part 28 of the furnace part 10 is cut off. 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 as the communication path portion 10 of the tape-shaped patterned conductor 16. In addition, as described above, in the secondary processing, the tape-shaped patterned conductor 16 (or the connecting conductor structure 4) is bent along the longitudinal bend lines on both sides of the communication path portion 10, preferably It is fixedly attached to the lead wire 3 by caulking in the connection part 9. In order to bend easily, you may form the notch according to a bend line in the tape-shaped patterned conductor 16 previously. The tape-shaped patterned conductor 16 may be cut at an appropriate portion so that the formed light source connecting member 6 has a suitable length for easy handling. Secondary processing of the tape-shaped patterned conductor 16, which may include such processing steps as ablation, bending, caulking and cutting, can be performed by a sequential transfer press. In addition, the bending of the tape-shaped patterned conductor 16 on the side of the second trunk path portion 12 in which the pilot hole 18 is engaged with the pilot pin of the sequential transfer press may be performed in the final step. Or you may carry out after taking out the produced light source connector 6 from a sequential feed press.

The part 27 of the communication path part 10 between the connection part 9 with respect to the lead wire 3 of the same light source 1 needs to be removed in any connection form, and this part 27 is tape-shaped patterned conductor. Although it may be not provided in the processing step of (16), by leaving this portion 27, it is possible to obtain the advantage of stabilizing the connecting portion 9 in the fixing and attaching process to the lead wire 3 of the connecting portion 9. have.

Fig. 7 is a diagram showing the procedure of secondary processing of the tape-shaped patterned conductor 16 for forming a parallel light emitting device. As described above, the cutout portion is shown with an oblique line, and the communication path portion 10 and the portion 27 between the pair of connecting portions 9 with respect to the lead wire 3 of the same light source 1 are cut off and adjacent to each other. The communication path part 10 part 29 which connects the connection part 9 with respect to the lead wire 3 of the light source 1 is excised. Further, as described above, the bent portion is bent along the lengthwise bend lines on both sides of the communication path portion 10, and the connecting portion 9 is fixedly attached to the lead wire 3 by caulking. In this connection form, the branch portions 13 and 14 remain unabated.

Fig. 8 is a diagram showing the procedure of secondary processing of the tape-shaped patterned conductor 16 to be a series light emitting device. As shown above, the cutout portion is shown with an oblique line, and the communication path portion 10 and the portion 27 between the pair of connecting portions 9 with respect to the lead wire 3 of the same light source 1 are cut off. The pair of trunk portions 11, 12 and branch portions 13, 14 are all cut off, leaving the connecting pieces 5 which are separate bodies from each other. Each connecting piece 5 has a form in which a pair of connecting portions 9 protrude in a direction along the lead wire 3 from both ends of the main body extending in a direction orthogonal to the lead wire 3. The lead wires 3 of the light source 1 are electrically connected to the lead wires 3 of the adjacent light sources 1 and are connected to each other at the same time to obtain a light source connector. Thus, in this embodiment, the connection conductor structure 4 which connects the light source 1 only in accordance with the connection piece 5 is formed.

FIG. 9 is a cross-sectional view showing a light-emitting device in which the light source connector 32 in series obtained by secondary processing shown in FIG. 8 is attached to a mounting board (holding body) 2. Here, the connecting piece 5 is not coupled to the lead wires 3 at both ends, and the lead wires 3 except for the both ends are simultaneously cut when the connecting piece 5 is cut out, and the attachment board 2 is removed. It does not protrude on the side. The lead wires 3 at both ends of the lever are cut into required lengths, inserted into the attachment holes 33 formed through the attachment boards 2, and connected to wirings 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 for forming a series light emitting device. As described above, the cutout portion is shown with oblique lines, and the communication path portion 10 and the portion 27 between the lead wires 3 of the same light source 1 are cut off, except that the first trunk portion 11 is here. All other things are cut off, leaving the branch 13 to be connected at one end (right in the drawing). In addition, the second trunk portion 12 is cut off together with the branch portion 14, leaving a portion connected to the connecting portion 9 located at the other end portion (left side in the drawing). In this example, unlike the above example, since the first and second trunk portions 11 and 12 remain, a power supply voltage can be applied thereto.

11A is a cross-sectional view showing another example of an attachment form to a holder of a light source connector. The connecting piece 35 of the light source connector 37 in this embodiment has protrusions on both ends thereof facing the attachment board 2 side, and the ends of the lead wires 3 also coincide with them. Then, the end of the lead wire 3 and the protrusion of the connecting piece 35 are inserted into the attachment hole 36 formed by being drilled in the attachment board 2 together, whereby the attachment board 2 of the light source connector 37 is provided. Support in the upper is achieved. This connecting piece 35 has the branch portion 14 of the tape-shaped patterned conductor 16 shown in FIG. 4A in the longitudinal direction with respect to both as well as one side of the pair of connecting portions 9 associated with each light source 1. And the secondary branch 14 together with the lead wire 3 of the light source 1 coupled to the tape-shaped patterned conductor when the secondary patterned tape-shaped conductor is installed at a position matched with the shape. It can form by cutting under the root of the part 12 side. In addition, the configuration may be such that the plurality of lead wires 3 inserted into the attachment holes 36 may be provided so that the plurality of lead wires 3 may be inserted into the attachment holes 36. Is set in consideration of the rigidity of the lead wire 3 and the connecting piece 35 and so on. As shown in Fig. 11B, the attachment hole 36 may be a recess 36 'like a groove instead of the through hole. Such recessed part 36 'may be integrally formed when the attachment board 2 is manufactured, for example, by molding, or may be formed by cutting after the attachment board 2 is molded. Alternatively, it may be formed by providing a plurality of protrusions on the attachment board 2.

FIG.12 and FIG.13 is a figure which shows the example which has arrange | positioned the light source 1 to the holding body. FIG. 12 shows an example in which the light source connector 42 is connected to a plurality of light sources 1 via the connection conductor structure 4 on the surface of the holding body (attachment board) 41 as a flat panel. The loop is formed by appropriately bending the connecting conductor structure 4, and the light source string by the light source connecting body 42 is arranged so as to show the outline of the characters. FIG. 13 shows an example in which the light source 1 is disposed on a curved surface, and the holder 51 forming a closed end surface of the light source connector 52 to which the plurality of light sources 1 are connected through the connection conductor structure 4 is formed. ) Can be wound. On the other hand, it is also possible to arrange the light source on the surface of the holding body to form a surface light-emitting body.

Fig. 14 is a front view showing a modified embodiment of the patterned conductor suitable for forming a series connection of the light sources, and Fig. 15 shows the secondary processing tips when the patterned conductor can be bonded to the light source 1. (The ablation part is shown with the diagonal line). In addition, in these figures, the same code | symbol is attached | subjected to the same part as FIG. 4A or 6, and detailed description is abbreviate | omitted. As shown, the patterned conductor 16 "for serial connection formation has a pilot hole 18 'formed in the communication path portion 10' for positioning or conveyance in a manufacturing line. It does not have the 1st and 2nd trunk path parts 11 and 12 shown in the figure, and the branch path parts 13 and 14 which connect these trunk path parts 11 and 12 to the communication path part 10, and the width | variety is narrowed by that. In this way, unnecessary materials can be saved at the time of completion of the light source connecting body, and the cost can be greatly reduced.

In the above embodiment, an example in which an LED is used as a light source has been shown, but the present invention is not limited thereto, and the present invention can be similarly applied to a light bulb having a lead wire and the like.

Thus, according to the embodiment based on the present invention, since a predetermined circuit pattern which can use various light source connectors having different light source connection patterns in common can be manufactured in the same manufacturing line from a tape-shaped patterned conductor formed in advance. In addition, productivity can be improved and manufacturing cost can be reduced, and a great effect can be obtained in reducing the manufacturing cost of a light emitting device using such a light source connector. Furthermore, since the light source is integrated as a light source assembly and then fixed to the holding body, it is possible to easily cope with various arrangements of the light source. In addition, since complicated processing is not required for the holding body, even if a small amount of a large variety of products is manufactured, an increase in manufacturing cost can be suppressed.

In the above embodiment, the light source has a pair of substantially parallel lead wires, and these lead wires extend along almost the main surface of the connecting conductor structure (patterned conductor). However, it is also conceivable that the light source is required to be attached in a direction extending substantially perpendicular to the main surface of the connecting conductor structure, or the case where the light source is made of a so-called chip type LED having no lead wire. The following embodiment of the present invention is suitable for such a case.

16 is a partial perspective view showing another preferred embodiment of a light source connector according to the present invention. As shown, this light source connector 101 uses a plurality of light emitting diodes (LEDs) 102 as light sources, each LED 102 having two parallel lead wires 103 as terminals for electrical connection. It is a so-called shell-type LED (also called a lamp-type LED). The plurality of LEDs 102 are arranged in a direction orthogonal to the lead wires 103 and are electrically connected by a connecting conductor structure 104 which is a substantially flat plate extending in this arrangement direction. In the example shown, the LEDs 102 are connected in series and parallel (ie, connected in parallel with a plurality of LEDs 102 connected in series), but as described later, the connection conductor structure 104 is Depending on the configuration, other connections such as serial connection and parallel connection are also possible.

The connection conductor structure 104 has first and second trunk paths 111 and 112 extending in the longitudinal direction to which a power supply voltage is applied, and therebetween, for connecting the lead wire 103 of the LED 102. The light source attachment part 105 and the communication path part 110 which connects these light source attachment parts 105 in the longitudinal direction are arrange | positioned. As can be seen from the figure, each light source attachment portion 105 has a pair of terminal connection portions 109 coupled to a pair of lead wires (terminals) 103 of one LED 102, in this embodiment. The pair of terminal connecting portions 109 are spaced apart from each other in the longitudinal direction. The first and second trunk paths 111 and 112 are electrically connected to the communication path 110 at predetermined portions by the branch paths 113 and 114 extending in the horizontal direction (width direction). A conductor pattern connecting 102 in series and parallel is constructed. In addition, the communication path 110 and the first and second trunk paths (111, 112) is preferably mechanically connected and integrally maintained by the insulating connecting member 115 extending in the width direction formed by the insert mold have.

Each terminal connecting portion 109 of the connecting conductor structure 104 is preferably formed with a cross-shaped hole 116, by pushing the lead wire 103 of the LED 102 corresponding to the hole 116, Mechanical / electrical connection of the connecting conductor structure 104 and the LED 102 is made. Since the holes 116 are cross-shaped, four inward protrusions are formed, and when the lead wires 103 are pushed in, these four protrusions are bent to function to reliably hold the lead wires 103. As shown in FIG. 17A, which is a cross sectional view along the line XVII-XVII in FIG. 16, the lead wire 103 is inserted into the hole 116, and then the holes 116 are fitted in the respective terminal connecting portions 109 so as to have width on both sides. The portion 117 extending in the direction is bent and the lead wire 103 is prevented from coming out of the undesired hole 116 more effectively by caulking to fit the lead wire 103. After caulking the lead wire 103 by the extension part 117, the lead wire 103 is cut | disconnected to an appropriate length. The lead wire 103 may be cut to a predetermined length in advance. As shown, the lead wire 103 attaches the light source connector 101 to the holder 123 by inserting it into a corresponding recess or hole 124 formed in the attachment board (retainer) 123. Can be used to

On the other hand, the connection between the terminal connecting portion 109 and the lead wire 103 is not limited to the insertion of the lead wire 103 into the hole 116 and the caulking of the lead wire 103 by the lead portion 117, but also spot welding, ultrasonic welding, and laser. Although it is possible by welding or the like, the above connection method has an advantage that there is no possibility of adversely affecting the LED 102 by heat, which can eliminate the use of solder, which can be continuously processed by a sequential transfer press. The insertion of the lead wire 103 into the hole 116 and laser welding may be used together. In this case, when the hole 116 has an inwardly projecting portion as shown in the drawing, when the lead wire 103 is inserted into the hole 116, the projecting portion is bent and pressed against the lead wire 103 so that the contact area becomes larger and the laser welding is further performed. It can be more surely achieved. In addition, a cutout is formed in a part of the communication path 110 adjacent to the hole 116 of the terminal connecting portion 109 to form a tongue, and the pair of extension portions 117 described above are bent by bending the tongue. As described above, the lead wire 103 may be caulked in three directions.

Furthermore, as shown in the cross-sectional view of FIG. 17B, a so-called "socket pin" 125 can be inserted into the hole 116 and used for the connection with the lead wire 103. The socket pin includes a conductor in which a socket portion (concave portion or female portion) is integrally formed on the back side of the pin portion (convex portion or male portion). You can use By pinching the pin portion of the socket pin in the hole 116 in advance, the electrical connection between the LED 102 and the connection conductor structure 104 can be facilitated by inserting the lead wire 103 into the socket portion of the socket pin.

According to the present invention, the connection conductor structure 104 as described above preferably has a circuit pattern which can be used in series, in parallel, and in parallel in parallel by pressing (punching) the conductive plate material. It is obtained by subjecting the patterned conductor formed by the secondary processing to cut the required part. By doing so, it is also possible to connect the LED 102 anywhere in series, in parallel, or in series parallel by changing the ablation section for the patterned conductor.

18 is a partial plan view showing a preferred embodiment 120 of a patterned conductor before secondary processing. In this figure, parts corresponding to the above-described connection conductor structure 104 are denoted by the same reference numerals. As shown, the patterned conductor 120 is a tape having a long dimension having self-supporting (ie, integrated with each part), and the contact path portion 110 extends in the longitudinal direction so that the light source attaching portion 105 Contacting). In addition, the light source attachment portion 105 and the communication path portion 110 are sandwiched in the width direction, and the first and second trunk path portions 111 and 112 are disposed on both sides of the patterned conductor 120. Each terminal connecting portion 109 of each light source attachment portion 105 is connected to the first and second trunk portions 111 and 112 by corresponding trunk portions 113 and 114. The communication path part 110 is connected to the lead wire 103 of another adjacent LED 102 (that is, included in the adjacent light source attachment part 105), and a plurality of connections respectively connecting a pair of terminal connection parts 109 to each other. The furnace 121 is included. The connection member 115 formed by the insert mold can be formed on this connection path 121 (see FIG. 16). At this time, a hole 119 is formed in the portion of the connection member 115 that matches the connection path 121 so as to expose the connection path 121 (the bridge of the connection path 121 exposed by the hole 119 is bridged. It is called part 121A (FIGS. 19-21). Accordingly, after the connection member 115 is formed, a punch (not shown) of the press machine is inserted through the hole 119 to cut off the bridge portion 121A, and the terminal connection portion (which has been in contact with the connection path 121). It is possible to segment 109).

Although the patterned conductor 120 becomes the connection conductor structure 104 which has the circuit of a predetermined connection pattern by performing secondary processing which cuts out a required part according to a use as mentioned above, this secondary processing is preferable. The connection is made after connecting the paths 111 and 112 and the communication path 110 by the connection member 115 formed by the insert mold. By doing so, it is possible to prevent each part of the formed connection conductor structure 104 from scattering. The formation of the connecting member 115 by the insert mold and the secondary processing of the patterned conductor 120 are efficient when the continuous production line is used. For this reason, the pilot hole 118 which is engaged with the pilot pin of a sequential feed press (not shown), for example is formed in the 2nd trunk | channel 112 for conveyance / positioning in a manufacturing line. .

The patterned conductor 120 as described above is preferably obtained by press working (more specifically, punching processing) of a conductive flat material made of a metal such as aluminum or copper. Aluminum is not used for printed circuit boards because it does not fit into solder, but it has the advantage that its specific gravity is small (about 1/3 of copper), making it suitable for weight reduction of products. It is also preferable that the thermal conductivity is high (multiplication of copper) and the conductivity is high. In addition, while the copper foil of the printed circuit board is about 35 µm, since the patterned conductor can be thickened to 100 to 300 µm, there is an advantage that the allowable current value can be large, and it is also preferable from the viewpoint of heat dissipation. It is also possible to form the patterned conductor 120 by photo-etching the conductive plate material or cutting the same by wire cutting, laser or electric discharge machining. It is also possible to form by diecasting such as magnesium molding. Since the patterned conductor 120 is flexible and flexible, it can be wound or coiled into a coil shape, so that storage, transportation, and packaging are easy.

19-21 is a figure which shows the method of the secondary processing of the patterned conductor 120 at the time of connecting LED 102 in series, parallel, parallel, and series, respectively. In these figures, an ablation part is shown with the diagonal line. In addition, the connection member 115 having the hole 119 is shown in dotted lines for easy understanding of the location of the ablation portion.

In the example of FIG. 19, a connection conductor structure capable of connecting a plurality of serial connectors (serial blocks) each including three LEDs 102 in parallel between the trunk portions 111 and 112 is provided. In detail, the bridge part 121A of the connection path 121 located between adjacent series blocks is cut | disconnected, and the connection path 121 which connects the terminal connection parts 109 in a series block is handled as it is. The branch portions 113 and 114 included in each serial block are connected to the branch portion 113 connected to the first trunk portion 111 at one end portion and to the second trunk portion 112 at the other end portion. All are left out, leaving the branch 114. It will be appreciated that the number of LEDs 102 that can be included in each series block can be changed by changing the branch portions 113 and 114 and the bridge portion 121A to be excised, and not limited to three. In addition, in the example of FIG. 19, the bridge portion 121A for connecting adjacent LEDs 102 included in the same series block to each other (that is, connecting the terminal connecting portions included in the adjacent light source attachment portions 105) is not removed. However, as indicated by the dotted lines in the perspective view of FIG. 16, for example, the contact 122 can be connected to the communication path 110 by spot welding, laser welding, or the like so as to insert the resistor 122 between the adjacent LEDs 102. In this case, the bridge portion 121A positioned between the both ends of the resistor 122 may be cut off. Similarly, when connecting the resistor 122 between the communication path part 110 and the 2nd main part 112 as shown by the dotted line, the branch part 114 in a corresponding position may be excised. It is also the same as when connecting between the communication path part 110 and the 1st trunk path part 111. FIG.

In the example of FIG. 20, all of the bridge portions 121A are cut off, and the branch portions 113 and 114 are connected to the respective LEDs 102 (ie, in each light source attachment portion 105). One of them is cut off so as to be connected to the trunk path 111 and the other to the trunk path 112. In this way, a connection conductor structure is provided in which a plurality of LEDs 102 attached to the light source attachment portion 105 are connected in parallel between the trunk portions 111 and 112.

In the example of FIG. 21, all of the branch portions 113 and 114 are cut off while the bridge portion 121A is left without being cut off to form a series of LEDs 102 between the trunk portions 111 and 112. It can be said that the connection piece for connecting the adjacent LEDs 102 is formed by the connection path 121 and the pair of terminal connection portions 109 contacted accordingly. As the light source connector 101 formed by connecting the LEDs 102 by the connection conductor structure thus formed, for example, the LEDs 102 positioned at both ends of the LED series without using the trunk portions 111 and 112. Although it is also possible to connect the power supply directly to the lead wire 103 of the lead wires 103, the paths 111 and 112 are connected to the LED series body by leaving the appropriate branch sections 113 and 114, and the paths 111 and 112 are connected to the power source. It is also possible to supply a voltage from the power supply to the LED series. Only one of the trunk portions 111 and 112 may be used for connection with such a power source.

As described above, according to the preferred embodiment of the present invention, the connecting conductor structure 104 having various connection patterns from the common patterned conductor 120 is replaced by changing the branch portions 113 and 114 and the bridge portion 121A. It will be understood that it is possible to form the {{{circle}}} and the light source connection body 101 with it. Although the formation of the connection conductor structure 104 by secondary processing of the patterned conductor 120 can be suitably made by press working, the temperance at the time of forming the connection conductor structure 104 of another connection pattern at that time is carried out. Selection of the branch portions 113 and 114 and the bridge portion 121A to be made can be made by computer control, for example, and it is not necessary to change the mold of the press machine, thereby eliminating time loss and work miss caused by the change of the mold, thereby improving productivity. It is possible to realize the improvement and the reduction of the manufacturing cost. In addition, since the printed circuit board is not used to form the light source connecting member 101, the solder normally used for connection with the printed circuit board can be eliminated, and the adverse effect on the environment is reduced, and the light source caused by the heat when the solder is used ( The bad influence on LED) can be eliminated. In addition, since it is an extremely simple structure composed of a light source (LED) and a connecting conductor structure, the use of a printed circuit board that is easy to disassemble and difficult to reuse does not require a reuse when it becomes unnecessary.

22 is a partial perspective view showing another embodiment of a light source connecting body according to the present invention. In the light source connecting member 151 shown in FIG. 22, instead of the lead wire 103, a pair of electrical connection terminals 153 extending from the side portion to the bottom surface portion are provided, and the light emitting portion 152A is provided on the surface thereof. The chip type LED (or surface mounting LED) 152 of the normal type is used as the light source. Such chip type LEDs are commercially available in the vertical, horizontal and height dimensions of several mm or less and extremely small, and can also reduce the size of the light source connector 151 manufactured using them.

Similar to the above embodiment, the LEDs 152 are electrically connected by a connecting conductor structure 154 obtained by secondary processing of a substantially flat patterned conductor 170 (see FIG. 25). Similarly, the connection conductor structure 154 has first and second trunk paths 161 and 162 extending in the longitudinal direction to which the power supply voltage is applied, and a light source attachment portion for connection with the LED 152 therebetween. A communication path 160 for connecting 155 (see FIG. 25) in the longitudinal direction is disposed. The first and second trunk paths 161 and 162 are electrically connected to the communication paths 160 at predetermined portions by the branch paths 163 and 164 extending in the width direction. A conductive pattern is connected to each other. A pilot hole 168 is formed in the second trunk path portion 162 to facilitate handling in a sequential transfer press. In addition, the communication path 160 and the first and second trunk paths 161 and 162 are mechanically connected by a connecting member 165 extending in the width direction formed by the insert mold.

In this embodiment, in order to mount the chip-shaped LED 152, a substantially box-shaped socket 172 having an opening on its surface is formed at a position that matches the light source attachment portion 155 of the connection conductor structure 154. Such a socket 172 can be preferably formed by an insert mold.

FIG. 23 is a plan view showing the socket 172 (the second from the left in FIG. 22) in which the LED 152 is not mounted, and FIG. 24 shows the socket 172 in the state where the LED 152 is mounted ( For example, it is a side sectional view which shows the left end of FIG. As shown in these figures, each light source attachment portion 155 of the connection conductor structure 154 has a terminal connection portion 159 isolated from each other in a pair of longitudinal directions, and these terminal connection portions 159 have a socket ( It is located on the bottom wall of the 172 and exposed, and when the LED 152 is inserted into the socket 172, the terminal 153 of the LED 152 and the terminal connecting portion 159 of the connection conductor structure 154 contact. It is. In addition, a small protrusion 167 is provided on the surface of each terminal connecting portion 159 to ensure contact between the terminal 153 of the LED 152 and the terminal connecting portion 159. Further, a hole 173 is formed in the bottom wall of the socket 172 so that the LED 152 can be removed from the socket 172 by pressing the LED 152 attached to the socket 172 there. Thus, the failed LED 152 can be exchanged for a normal one.

The connection conductor structure 154 in the embodiment shown in FIGS. 22 to 24 also has a second process for cutting a predetermined portion in a flat patterned conductor having a predetermined circuit pattern as in the embodiment of FIG. It is suitably formed by performing. FIG. 25 is a plan view showing a patterned conductor 170 before secondary processing suitable for use in the embodiments of FIGS. 22 to 24. In this figure, the same code | symbol is attached | subjected to the part corresponding to FIGS. 22-24.

Similar to the patterned conductor 120 shown in FIG. 18, the patterned conductor 170 is also in the shape of a tape having a long dimension, and the contact path portion 160 which connects the light source attachment portion 155 in the longitudinal direction is in the longitudinal direction. It is serialized. Further, the light source attachment portion 155 and the communication path 160 are sandwiched in the width direction, and the first and second narrow passage portions 161 and 162 are disposed on both sides of the patterned conductor 170. Further, each terminal connection portion 159 of each light source attachment portion 155 is connected to the first and second trunk path portions 111 and 112 by corresponding branch portions 163 and 164. The communication path 160 is a plurality of connections each connecting a pair of terminal connecting portions 159 connected to the terminals 153 of other adjacent LEDs 152 (that is, included in the adjacent light source attachment portion 155). The furnace 171 is included. The connecting member 165 formed by the insert mold is formed on the center in the longitudinal direction of the connection path 171 (see Fig. 22). At this time, the hole 169 is formed in the part of the connection member 165 which matches with the connection path 171 so that the connection path 171 may be exposed (the part of the connection path 171 exposed by the hole 169 is formed). Bridge portion 171A}. Accordingly, after the connection member 165 is formed, a punch (not shown) of the press machine is inserted through the hole 169 to cut off the bridge portion 171A, and the terminal connection portion (contacted through the connection path 171 ( It is possible to segment 159). In this embodiment, the bridge portion 171A exposed by the hole 169 is formed to be relatively narrow so as to be surely exposed by the hole 169 of the connecting member 165 and to facilitate cutting. On the other hand, the shape of the bridge portion 171A may be arbitrary and may include, for example, two thin paths intersecting crosswise. In addition, you may put a perforation line in the appropriate part of the connection path 171 so that ablation may be easy.

In this embodiment, the tongue piece 174 extending in the longitudinal direction by the cutout part is formed in the part of the connection path 171 adjacent to the terminal connection part 159 of the light source attachment part 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 174 is bent, and the LED 152 is undesirably pressed by pressing the LED 152 mounted on the socket 172 from above. ) To prevent falling off.

26 to 28 show a method for secondary processing of the patterned conductor 170 so as to form the connection conductor structure 154 for series parallel, parallel, and series connection from the patterned conductor 170 shown in FIG. Is showing. 19-21, the part cut off is shown with the diagonal line. In addition, the socket 172 and the connection member 165 are shown in dotted lines for easy understanding of the location of the ablation portion. Since the description of FIGS. 26 to 28 is almost the same as the description of FIGS. 19 to 21, the descriptions of FIGS. 19 to 21 are omitted. It is possible to form.

FIG. 29 is a partial perspective view showing a modified embodiment of the embodiment shown in FIG. 22. 22, the same code | symbol is attached | subjected to the same part as FIG. 22, and detailed description is abbreviate | omitted. This light source connector 151 'differs from the embodiment shown in Fig. 22 in that a so-called side view type LED 152' having a light emitting portion 152A 'is used as a light source. In the socket 172 'to which the LED 152' is mounted, a part of the sidewall is cut off to form the opening 176, and the light emitted from the LED 152 'is not disturbed. On the other hand, openings are formed in both side surfaces of the socket 172 ', so that the LEDs 152' can be mounted in a different direction, and light can be radiated to both sides.

30 is a partial perspective view showing another modified embodiment of the embodiment shown in FIG. 22. In this figure, the same code | symbol is attached | subjected to the same part as FIG. 22, FIG. 29, and detailed description is abbreviate | omitted. In this light source connector 151 ", the socket 172" extends over the whole width | variety of the connection conductor structure 154, and differs from the embodiment of FIG. 22 in that it functions as the connection member. In this way, the part of an insert mold can be reduced and manufacturing cost can be reduced. Also, as in the embodiment of Fig. 29, a portion of the side wall of the socket 172 " is cut out to form the opening 176 so that the side view type LED 152 'can be used as the light source. Since they are provided on both sides of the socket 172 ", the LED 152 'can also be attached in the reverse direction to that shown in FIG. It is of course also possible to use the normal type LED 152 as a light source.

FIG. 31 is a perspective view showing still another modified embodiment of the embodiment shown in FIG. 22. FIG. 22, the same code | symbol is attached | subjected to the same part as FIG. 22, and detailed description is abbreviate | omitted. Each terminal connection part 159 'of each light source attachment part 155' of the connection conductor structure 154 'of this light source connection body 151a has a pair of extension parts 175 extending in the width direction. The bilateral directional lead portion 175 is bent by a press machine to be roughly perpendicular to the main surface of the connecting conductor structure 154 ′ and forms an opposing wall to hold the chip-shaped LED 152 therebetween, thereby holding the LED 152 therein. Can be attached to the connecting conductor structure 154 '. Thereby, the socket 172 formed by the insert mold becomes unnecessary like FIG. 22, and manufacturing cost and working time can be reduced by that. On the other hand, as in the embodiment of Fig. 22, the chip-shaped LED 152 electrically connected to the terminal connection portion 159 'of the light source attachment portion 155' of the connection conductor structure 154 'is close to the connection portion 159'. It is preferable to raise the tongue tongue 174 formed in the connection path 171 by the cutout portion extending in the longitudinal direction, and to apply a pressing force from above by the tongue tongue 174, thereby preventing unwanted dropout. .

In addition, in the embodiment of Fig. 31, the LED 152 is not attached to the pair of terminal connection portions 159 'of the second light source attachment portion 155' from the right side. Are connected to each other by the bridge portion 159A, and two LEDs 152 from the left side and two LEDs of the LED 152 on the right side are connected in series. As described later with reference to FIG. 32, this is a pair of terminal connection portions at the time of primary processing in which the tape-shaped patterned conductor 170 ', which is the basis of the connection conductor structure 154', is manufactured by press working. The bridge portion 159A for connecting the 159 'is formed, and in secondary processing, only the bridge portion 159A in the light source attachment portion 155' to which the LED 152 is attached is cut off, and the LED 152 is The bridge portion 159A of the unconnected light source attachment portion 155 'can be realized by leaving it as it is. By doing so, it is possible to adjust the spacing between adjacent LEDs 152 in the completed light source connector 151a. On the other hand, in the embodiment of Fig. 31, the LEDs 152 are all attached to the same side of the connection conductor structure 154 '(upper side in the figure), but by inverting the bending directions of the extension section 175 and tongue tongue 174. It is also possible to attach the LED 152 to the other side (lower side in the figure).

Further, in the embodiment of Fig. 31, a chip-type resistor (or also referred to as surface mounting resistor) 156 is connected between the communication path 160 and the second trunk path 162. For this reason, the connection conductor structure 154 ′ of FIG. 31 is formed from the communication path part 160 and the care path part 162 in the communication path part 160 and the second path part 162 to which the resistor 156 is connected. It has a pair of resistance terminal connection part 178 extended toward each other. That is, the resistance attaching portion 177 is formed by the pair of resistance terminal connecting portions 178. Like the (light source) terminal connecting portion 159 'for the LED 152, each resistance terminal connecting portion 178 is also provided with a pair of directing portions 179 that are bent by a press to form opposing walls. The chip resistor 156 is inserted between these opposing walls 179, and the pair of terminals 157 of the chip resistor 156 are welded to the resistor terminal connecting portion 178 by, for example, laser welding. Bonding). Laser welding is preferably performed by bringing the laser light into one or a plurality of points on the opposite side to which the resistor 156 of the resistor terminal connecting portion 178 is attached, but on the side where the resistor 156 is attached. It is also possible to make a laser beam touch. By welding, the chip resistor 156 can be prevented from falling off from the connection conductor structure 154 'undesirably. If the connecting conductor structure 154 'is made of aluminum, such laser welding can be made highly reliable, which is preferable. It is more preferable if silver plating is carried out. Also, arc welding, ultrasonic welding, spot welding (resistance welding) and the like can be considered. However, since the terminal 157 of the chip resistor 156 is usually very thin and easily damaged, the laser welding is required to minimize the possibility of such damage. desirable. Instead of welding, it is also possible to use a conductive adhesive containing, for example, a powder of aluminum nitride, but welding is generally preferred from the viewpoint of mechanical strength. In this way, the resistor 156 is connected in series with the LED 152 by enabling the resistor 156 to be connected between the communication path 160 and the second trunk path 162. ) Can be prevented from applying an overvoltage.

In addition, in the embodiment of FIG. 31, the connecting member is formed by the insert mold to extend in the width direction of the connection conductor structure 154 'so as to connect the communication path 160 and the pair of trunk paths 161 and 162 ( 165 'is the same length as the width of the connecting conductor structure 154'. As shown later in FIG. 32, the direction recess 166A or the through-hole 166B is formed in a part of a pair of path | route path | route part 161, 162, and these direction recesses 166A or the through-hole 166B are replaced. Through this, a part of the connection member 165 'formed by the insert mold extends in the up and down direction of the drawing and is firmly connected to the trunk portions 161 and 162, so that the displacement of the connection member 165' in the longitudinal direction is displaced. It is made possible by being prevented.

32 is a plan view of the patterned conductor 170 ′ used to form the light source connector 151a of FIG. 31. In this figure, the same parts as in FIG. 25 are denoted by the same reference numerals and detailed description thereof will be omitted. As shown, the patterned conductors 170 'each have a plurality of light source attachment portions 155' to which the chip LEDs 152 can be attached, and each light source attachment portion 155 'is a chip LED. A pair of terminal connecting portions 159 'corresponding to the pair of electrical connection terminals 153 of 152 are provided. Each terminal connecting portion 159 'has a widthwise extending portion 175 extending in a pair of opposing directions, and the secondary processing of the patterned conductor 170' when forming the connecting conductor structure 154 '. By bending these directing portions 175 during (press processing), a wall for holding or positioning the chip LED 152 as shown in FIG. 31 can be formed. In addition, a notch (groove) may be formed in the base portion of the extension portion 175 to facilitate bending processing.

In the patterned conductor 170 'of FIG. 32, as described with reference to FIG. 31, a bridge portion 159A is formed between a pair of terminal connection portions 159' of each light source attachment portion 155 '. So that only the bridge portion 159A of the light source attachment portion 155 'to which the LED 152 is connected during secondary processing of the patterned conductor 170' forming the connection conductor structure 154 'can be cut off. It is. In the patterned conductor 170 ′, a part of the branch path 164 connecting the communication path 160 and the second path part 162 is formed between the communication path part 160 and the care path part 162. Is replaced by a resistor attaching portion 177 for connecting the chip resistor 156 to the chip resistor. Each resistor attachment portion 177 has a pair of resistance terminal connection portions 178 corresponding to a pair of electrical connection terminals 157 of the chip type resistor 156, and the patterned conductor 170 'before secondary processing. In this case, the pair of resistance terminal connecting portions 178 are connected to each other by the bridge portion 178A, and the bridge portion 178A is cut off in the secondary processing only when the resistor 156 is actually connected. If the resistor 156 is not connected and the bridge portion 178A is left, it functions as a conductor connecting only the communication path portion 160 and the second path portion 162, as in the conventional branch portion 164. Will be understood. In the embodiment of Fig. 32, a part of the plurality of branch portions 164 is formed as the resistor attaching portion 177, but all of the branch portions 164 may be used as the resistor attaching portion 177. 31 and 32, although the resistor attachment portion 177 for attaching the resistor 156 is provided between the communication path portion 160 and the second path portion 162, the communication path portion 160 ) And the first path part 161 can of course be installed.

As described above, the patterned conductor 170 ′ of FIG. 32 has a semicircular directional recess 166A at the first trunk path 161 at a location corresponding to the position where the connection member 165 ′ is installed. The through hole 166B is formed in the second trunk part 162. By doing so, a portion of the connecting member 165 'formed by the insert mold extends through these directional recesses 166A and through holes 166B, so that the connecting member 165' is formed of the patterned conductor 170 '. Even if the length is the same as or shorter, it is possible to firmly couple the connecting member 165 'and the trunk portions 161 and 162. In Fig. 32, a widthwise recess is provided in the first narrow path part 161, and a through hole is provided in the second narrow path part 162, which is relatively wide. A part of the connection member 165 'should just be able to penetrate a part of these trunk parts 161 and 162 in an up-down direction. Of course, the shape of the direction recess 166A and the through hole 166B is arbitrary, and is not limited to a semicircle or a circular shape.

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. FIG. In this figure, the same parts as in FIG. 18 are denoted by the same reference numerals, and detailed description thereof will be omitted. As shown, this patterned conductor 120 'includes a first trunk path 111 shown in FIG. 18 and a branch path 113 for connecting the first trunk path 111 to the communication path 110. As shown in FIG. We do not have, and width is narrowed by that much. By doing so, it is possible to save the material which becomes unnecessary at the completion of the light source connector and to reduce the cost. In addition, since the patterned conductor 120 'is the same as the patterned conductor 120 of FIG. 18 except that it does not have the trunk portion 111 and the branch portion 113, the patterned conductor 120 of FIG. Can be processed with the same sequential feed press used for

34 is a partial plan view showing a modification of the patterned conductor of FIG. 25 suitable for forming a series connection of LEDs. In this figure, the same parts as in FIG. 25 are denoted by the same reference numerals, and detailed description thereof will be omitted. Like the patterned conductor 120 'shown in FIG. 33, the patterned conductor 170 "also does not have the first trunk portion 161 and the branch portion 163, thereby reducing the cost due to material reduction. ought.

FIG. 35 is a partial perspective view as in FIG. 16 showing another embodiment of the connecting member. FIG. In this figure, the same parts as in FIG. 16 are denoted by the same reference numerals, and detailed description thereof will be omitted. In the light source connecting member 101 ', the connecting member structure 104 (or the patterned conductor 120) in the width direction is used as a connecting member for connecting the two path portions 111 and 112 and the communication path 110. For example, a plurality of insulating sheets 184 made of, for example, vinyl chloride are used. The insulating sheet 184 may be attached to the patterned sheet 120 including the trunk portions 111 and 112 and the communication path 110 before the secondary processing. Although it is preferable to use an adhesive agent for such adhesion | attachment, it can also stick by other arbitrary suitable methods, such as heat welding and UV hardening of resin. When the sheet 184 is used, compared with the case where the insert mold is used, the mechanical strength of the light source connector to be formed can be made smaller or thinner than that of the insert mold. In addition, the insulating sheet 184 can be perforated together by a press during the secondary processing of the tape-shaped patterned conductor 120.

36 is a partial perspective view like FIG. 16 showing still another embodiment of the connecting member, and FIG. 37 is a bottom view thereof. In these drawings, the same parts as in FIG. 16 are denoted by the same reference numerals, and detailed description thereof will be omitted. If it is the light source connector 101 ", it is a connecting member for connecting both path parts 111 and 112 and the communication path 110, and the width direction of the connection conductor structure 104 (or the patterned conductor 120) is carried out. In addition, the insulating sheet 184 'made of, for example, vinyl chloride is used, which extends over a predetermined length in the longitudinal direction thereof, and the insulating sheet 184' is, for example, a patterned conductor. The insulating sheet 184 'may also be attached to the patterned conductor 120 using an appropriate means such as an adhesive before secondary processing of the patterned conductor 120. In addition, a predetermined portion of the insulating sheet 184 '(for example, a portion that matches the pilot hole 118 and a portion where the lead wire 103 of the LED 102 is inserted) may be drilled. In the example, as shown in the bottom view of FIG. 37, the laser for laser welding is downward. An opening 185 is provided to expose the terminal connecting portion 109 (or the light source attaching portion 105) of the connecting conductor structure 104 so that it can be touched. As in the embodiment using the plurality of insulating sheets 184 shown in Fig. 2, the light source connector formed in comparison with the case of using the insert mold can be made smaller or thinner. Compared to the case in which it is used, it is relatively easy and can be attached to the patterned conductor 120 in a short time, and in FIG. However, it is only necessary to be able to connect the two paths 111 and 112 and the communication path 110, and it is not necessary to extend the whole width direction, and for example, the pilot hole 118 is not clogged with the width. You may.

As shown in FIG. 36, in the case of the light source connector 101 "using the insulating sheet 184 'as a connecting member, as shown in FIG. By bending the branch portions 113 and 114 so as to be perpendicular to the main surface of the light source, and inserting the trunk portions 111 and 112 into the matching grooves 181 and 182 formed in the attachment board (retainer) 180, the light source is connected. The attachment of the sieve 101 "to the attachment board 180 can be facilitated. A groove or a hole may be formed in the attachment board 180 so as to accommodate, for example, the lead wire 103 of the LED 102, etc. protruding from the lower surface of the light source connector 101 ". May be formed so as to be integrated with the light source connecting body 101 by molding. Further, a plurality of light source connecting bodies 101 "are disposed on the attachment board 180 side by side in the width direction to form a surface light source. It is possible. In that case, it is preferable to adjust so that the pitch of the LED 102 of a vertical direction and a horizontal direction may become the same. In the light source connecting member 101 shown in FIG. 16, the connecting parts 111 and 112 and the contact path 110 of the connecting conductor structure 104 are connected by the connecting member 115 formed by the insert mold. Although the LED 102 is attached to the connecting conductor structure 104, the both paths 111 and 112 and the communication path 110 are integrally connected through the LED 102 and the branch portions 113 and 114. As a result, the connecting member 115 can be removed. Even in such a case, as shown in FIG. 38, the light source connector 101 can be attached to the attachment board. The same applies to the light source connector shown in FIG. 22.

FIG. 39 is a perspective view showing an embodiment 190 of a light emitting device using the light source connector 101 "using the insulating sheet 184 'shown in FIG. 36 as a connecting member, for example. 41 is a schematic plan view according to XL-XL, and in these drawings, the same parts as shown in Fig. 36 are denoted by the same reference numerals, and detailed description thereof will be omitted. In this example, each of the _N LED series blocks L _{1 to} L N included in the light source connector 101 ″ is provided with four LEDs 102 and chip resistors 156 (connected in series with these LEDs 102). 31). The chip-shaped resistor 156 cuts a part of the contact path portion 110 (or the connection path 121) between the adjacent LEDs 102, and arranges the resistor 156 to cross the cut-off portion of the resistor 156. The terminal can be attached by laser welding the connection path 121. In addition, the number of LEDs 102 included in each serial block L _{1 to} L _N can of course be varied.

The illustrated light emitting device 190 is a housing for accommodating the light source connector 101 ″, and has, for example, a cylindrical tubular member 191 having a light transmittance such as a glass tube. By using a small size, the tubular member 191 can be used, for example, having a diameter of 0.5 to 2 cm, The translucent tubular member 191 can also be formed from plastics, etc. Likewise, a glass tube having good heat transfer characteristics is preferable for efficient heat dissipation.

Cap members 192 are mounted at both ends of the tubular member 191, and a pair of conductive pins 193 are held at each cap member 192. One of the 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 the second trunk section. Thus, for example, a pair of conductive pins 193 provided at one end portion of the tubular member 191 is connected to a power supply, for example, through the trunk portions 111 and 112. A power supply voltage can be supplied to the LED 102 of the light source connector 101 ".

As described above, according to the present embodiment, since the trunk portions 111 and 112 of the light source connector 101 '' can be used as wiring (or electric circuit) for connecting the LED 102 to the power source, Compared with this, the work efficiency of assembly and the like can be greatly improved, and it is possible to connect the separate light emitting device 190 through the corresponding conductive pin 193, and by repeating this, any number of light emitting devices In this case, for example, the conductive pins 193 at one end are male, and the conductive pins 193 at the other end are formed so that the light emitting device 190 can be easily connected to each other. It is also possible to use a female connector, or it is possible to use a dedicated connector cable for the connection, and when the device 190 is used only as a unit, the first and second of the light source connector 151. The trunk portions 111 and 112 are tubular members 191. It may be connected only to the conductive pin 193 is provided on the end portion of one side.

In the light emitting device 190 shown in FIGS. 39 to 41, heat is generated from the resistor 122 and the LED 102 during use. In addition, since both ends of the tubular member 191 are sealed by the cap member 192, when the diameter of the tubular member 191 goes from 0.5 to 2 cm, tropical flow hardly occurs. Therefore, when the printed circuit board is used, the copper foil used for circuit formation is usually thin about 35 µm, and thus the heat transfer efficiency is poor (i.e., the heat transfer rate is low). Therefore, heat generated from elements such as the resistor 122 or the LED 152 is used. It stops around this, and there exists a possibility that the temperature of the element surroundings may rise excessively, and the element may be damaged or the performance may fall by this. However, the light emitting device 190 shown in Figs. 39 to 41 has a light source connector having a connecting conductor structure 104 (Fig. 38) that can be formed by pressing conductive (primary and secondary) materials. 101 "), and the thickness of the flat plate material is usually 0.1 to 0.3 mm, which can be significantly thicker than the copper foil of the printed circuit board. Therefore, the thermal conductivity is extremely good compared to the printed circuit board, It is possible to suppress the excessive rise of the temperature around the element and to achieve a substantially uniform temperature distribution in the tubular member 191.

Further, in the first and second trunk path portions 111 and 112, a plurality of arc-shaped heat transfer plates 194 having elasticity, preferably made of metals such as aluminum, which serve as heat transfer members, are welded or screwed, for example. It is attached by. The heat transfer plate 194 also serves as a support for supporting the light source connector 101 ″ in the tubular member 191. As shown in the cross-sectional view of the drawing, the heat transfer plate 194 is the tubular member 191. It has a cross-sectional shape almost along its inner surface and is pressed against the tubular member 191 in close contact with the tubular member 191. Accordingly, the tubular shape is formed from the first and second trunk paths 111 and 112 through the heat transfer plate 194. Since heat is transferred to the member 191 and heat is dissipated to the outside from the tubular member 191 made of glass, the temperature rise in the tubular member 191 can be further suppressed. The tubular member 191 itself can be acted as a heat sink by using 194. In addition to the tubular member 191 made of glass, for example, it is made of an insulator having good heat transfer such as ceramics. The light source connector 101 "is housed in the housing (receptor). Even when used to transfer heat to the housing by using the same heat transfer plate 194 described above, so that it is possible to dissipate heat from the housing to the outside. In the illustrated example, a relatively small heat transfer plate 194 is used, but a heat transfer plate 194 extending over substantially the same length as the tubular member 191 may be used. In addition, the shape of the housing is not limited to a tubular shape, and the shape of the heat transfer plate 194 can be changed in various ways according to the shape of the housing. In addition, if part or all of the surface and / or the lower surface of the light source connector 101 "is black, it is more preferable because it can radiate heat as infrared rays. This is, for example, black nickel plating, black chromium plating, chromate. By treatment, or by using alumite in the material.

In this embodiment, the individual light sources consisted of a single light emitting element such as, for example, a shell-shaped LED 102 having two leads or a so-called chip-shaped LED 152 having no leads. However, as shown below, one light source may be made of a light emitting element assembly including a plurality of light emitting elements.

42A is a perspective view for explaining an embodiment using such a light emitting device assembly 195 as a light source. In this embodiment, as the connecting conductor structure 104, as shown in Fig. 20, a secondary processing of the tape-shaped patterned conductor 120 for parallel connection of a light source can be used. In FIG. 42A, the same parts as in the above embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In the case of configuring a circuit for parallel connection in this manner, the pair of terminal connecting portions 109 of the light source attaching portions 105 of the connecting conductor structure 104 are respectively connected via the corresponding branch portions l13 or 114. Since it is connected to the trunk path 111 or 112, the connection member 115 by the insert mold for preventing each part of the connection conductor structure 104 from cluttering is unnecessary.

In the embodiment of Fig. 42A, the light emitting element assembly 195 as a light source is one of six chip-shaped LEDs 196 arranged in line and electrically connected to a support 198 made of, for example, a printed board. It has a chip resistor 197. The light emitting element assembly 195 is spaced apart at intervals corresponding to the pair of terminal connection portions 109 of the light source attachment portions 105 of the connection conductor structure 104, and serves as a terminal for electrical connection. Has a pair of lead wires or conductive pins 199 extending along the line. 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. 42B. In this way, the lead wire 199 is inserted into the connection hole 116 formed in the terminal connection portion 109, so that the light emitting element assembly 195 as the light source is connected to the connection conductor structure 104 in the same manner as described for the embodiment of FIG. ) Can be connected. In this way, the light emitting element assembly 195 can be attached to the connection conductor structure 104 as a light source, thereby enlarging the change in the lighting effect. For example, as shown in FIG. 42A, by using the light emitting element assembly 195 as a plurality of light sources, the adjacent ones are arranged to be closely adjacent to each other in the longitudinal direction, thereby eliminating dark portions between the light source and the light source, thereby making it more uniform. Lighting without spots can be realized. Instead of forming the light emitting device assembly 195 using a printed circuit board as the support 198, the light emitting device assembly 195 may be replaced with a light source connector 151 as shown in Figs. 151 ') can be formed.

43A and 43B show an example in which a separate light emitting element assembly is used. FIG. 43A is a perspective view for explaining an embodiment of a light source connector using such a light emitting device assembly 195 'as a light source, and FIG. 43B is a circuit diagram of the light emitting device assembly 195'. In Figs. 43A and 43B, the same parts as in Figs. 42A and 42B are denoted by the same reference numerals and detailed description thereof will be omitted. The light emitting element assembly 195 'is arranged in parallel with five LEDs 196 and one resistor 197 in series, for example, on a support 198' having a printed circuit board. It becomes one structure and two-dimensional light emission is enabled. This embodiment is also a terminal for electrical connection connected to the terminal connection portion 109 of the connection conductor structure 104, as in the embodiment shown in Fig. 42, wherein the LED 196 and the resistor 197 of the support 198 ' On the opposite side to the attached surface, it has a pair of lead wires or conductive pins 199 that extend substantially in parallel at predetermined intervals. As shown, the light emitting device assembly 195 'can have the same width as the connection conductor structure 104. As shown in FIG. In this case, when the light source connectors using the light emitting device assembly 195 'are arranged side by side in the width direction, the gaps between adjacent light source connectors can be appropriately adjusted to provide illumination without spots as a whole. In addition, it is preferable to arrange the plurality of light emitting device assemblies 195 'in a longitudinal direction so that the dark portion between the light source and the light source can be lost. The shape of the light emitting element assembly 195 'is not limited to a square or a rectangle, but may be any arbitrary shape such as a circle. In the above embodiment, although the tape-shaped patterned conductor 120 is secondary processed for the parallel connection of the light source as the connection conductor structure 104, the connection method of the light emitting element in the light emitting element assembly, the magnitude of the resistance, etc. By appropriately selecting, it is also possible to use the secondary processing (FIG. 19, FIG. 21) for other connection such as serial parallel connection or serial connection.

For example, the light source connector 151a using the chip-shaped LED 152 as the light source can be used by bending it in the longitudinal direction because the connection conductor structure 154 'is almost flat and flexible. Do. However, in the embodiment of Fig. 31, a pair of electrical connection terminals 153 (and a corresponding pair of terminal connection portions 159 'of the connection conductor structure 154') of each chip type LED 152 are connected to the light source. Since it is arranged so as to be spaced apart in the longitudinal direction of the sieve 151a (that is, the connecting conductor structure 154 '), when the light source connecting member 151a is bent, the terminal connecting portion of the connecting conductor structure 154' ( 159 ') and a force to separate the terminal 153 of the LED 152 can be operated. In the embodiment of FIG. 31, the LED 152 is pushed on the tongue piece 174 from above, but a force such as separating them from the electrical contacts (ie, the terminal 153 and the terminal connector 159 ′) is connected. It is not preferable from the viewpoint of defect prevention. Although it is also possible to weld the LED 152 and the connection conductor structure 154 'by laser welding etc., it is the same that it is not desirable that such a force acts.

The example of the tape patterned conductor shown in FIG. 44 is suitable so that such a problem may not arise. As shown in the figure, the patterned conductor 200 can also be formed by press working to have a predetermined pattern as in the above-described embodiment, and the required circuit configuration can be achieved by performing secondary processing for cutting off appropriate portions. It is possible to form an excitation connecting conductor structure. That is, the patterned conductor 200 is for electrical connection with the first and second trunk paths 211 and 212 extending substantially parallel to the longitudinal direction and the chip-shaped LED 202 (see FIG. 45) as a light source. A plurality of light source attachment portions 215 arranged in the longitudinal direction between these trunk portions 211 and 212, a communication path portion 210 for communicating these light source attachment portions 215 in the longitudinal direction, and a communication passage portion ( It has a plurality of branch sections 213 and 214 for connecting the 210 and the trunk sections 211 and 212 in the width direction, and the appropriate branch sections 213 and 214 are cut off so that various connection forms such as serial, parallel, series parallel, and the like are provided. The connection conductor structure for connecting the chip-shaped LEDs 202 can be formed.

In the embodiment of FIG. 44, each light source attaching portion 215 is provided with a pair of light source terminal connecting portions 216 spaced apart from each other in a direction substantially perpendicular to the longitudinal direction of the patterned conductor 200 (ie, the width direction). Have Accordingly, when each chip-shaped LED 202 used as a light source is attached to the corresponding light source attachment portion 215, as shown in FIG. 45 below, a pair of terminals 203 of each LED 202 The patterned conductors 200 are spaced apart from each other in a direction substantially perpendicular to the length direction of the patterned conductors 200 (i.e., the connecting conductor structures formed thereafter).

Each terminal connecting portion 216 has a pair of directing portions 217 directed in the longitudinal direction of the patterned conductor 200. This extension portion 217, like the extension portion 175 of the embodiment shown in FIG. 31, is bent perpendicularly to the main surface of the patterned conductor 200 to form a wall for holding or positioning the LED 202. FIG. In addition, although the pair of terminal connection part 216 of each light source attachment part 215 is isolate | separated from each other in the example shown, like the embodiment shown in FIG. 31, FIG. Only when attached, the patterned conductor 200 may be separated in the secondary processing.

In the patterned conductor 200 of FIG. 44, a resistance attaching portion 225 for attaching a chip resistor 205 (see FIG. 45) is provided between two light source attaching portions 215 on the left side of the drawing. Like the light source attachment portion 215, the resistance attachment portion 225 has a pair of resistance terminal connection portions 226 spaced apart in the width direction of the patterned conductor 200. Each terminal connecting portion 226 has a pair of directing portions 227 directed in the longitudinal direction of the patterned conductor 200. This extension part 227 is bent perpendicularly to the main surface of the patterned conductor 200, like the extension part 179 of the embodiment shown in FIG. 31, and forms the wall for holding or positioning the resistance 205. FIG. By providing the resistor attaching portion 225 in this way, it is possible to easily realize that the adjacent LEDs 202 are connected via the resistor 205, and the pair of terminals 206 of the attached resistor 205 can be realized. Is spaced apart in a direction substantially perpendicular to the longitudinal direction of the patterned conductor 200. When the patterned conductor 200 is formed, a pair of resistance terminal connecting portions 226 of the resistor attaching portion 225 are connected to each other, and only when the resistor 205 is attached, two of the patterned conductors 200 are connected. The separation in the machining is similar to that of the light source attachment portion 215.

In the patterned conductor 200 of FIG. 44, the first and second trunk paths 211 and 212 extend in the longitudinal direction while meandering. In detail, these trunk paths 211 and 212 have a portion substantially matched in the longitudinal direction with the light source attachment portion 215 to which the LEDs 202 are attached, in the width direction outward direction (ie, the direction from the contact path portion 210). } Is curved in a convex shape to form convex curved portions 211A and 212A. In addition, although each convex curved part 211A, 212A is curved in a substantially "c" shape as drawing, it may be curved in circular arc shape, for example. As a result, the convex curved portions 211A and 212A of the trunk portions 211 and 212 are bent at their root portions so as to be substantially perpendicular to the main surface of the communication path 210, and the curved portions can be used for attachment to a support plate or the like. (See FIG. 45). In addition, since the narrow path portions 211 and 212 are formed relatively narrow in this patterned conductor 200, the tape-shaped patterned conductor 200 can be easily handled in a sequential feed press (not shown). The edge plate part 219 with the pilot hole 218 which is engaged with the pilot of a sequential transfer press machine is extended in the longitudinal direction, and is installed in the 2nd path | route part 212 and the some connection part 220 so that the pilot board 218 may engage. Connected by The edge plate portion 219 is separated from the second path portion 212 by cutting off the connecting portion 220 in the secondary processing of the tape-shaped patterned conductor 200 by a press, for example, in a final process.

FIG. 45 is a perspective view of a light source connecting body 201 formed using the patterned conductor 200 shown in FIG. 44 and a holding body 230 for holding it. As shown, the light source connector 201 has a chip-shaped LED 202 in the connection conductor structure 204 formed to cut out a predetermined portion of the patterned conductor 200 shown in FIG. 44 to have a required circuit configuration. And chip type resistor 205. In detail, the pair of longitudinal extension portions 217 of the light source terminal connecting portions 216 of the connection conductor structure 204 are bent to form opposing walls, and the chip-shaped LED 202 is inserted therebetween as a light source. Attached. Since a pair of terminal connecting portions 216 for each LED 202 are arranged apart from each other in the width direction of the light source connector 201, a pair of electrical connection terminals of each LED 202 in the attached state. It will be appreciated that 203 is also located along the width direction. In this embodiment, since there is no tongue piece 174 as shown in Fig. 31 which pushes the LED 202 upward, the connection between the terminal connecting portion 216 and the terminal 203 of the LED 202 is an example. For example, it may be performed by welding such as laser welding. Similarly, the chip-shaped resistor 205 is attached to the resistor attachment portion 225 provided between the light source attachment portions 215. The pair of longitudinal extension portions 227 of the resistance terminal connecting portions 226 of the resistor attachment portion 225 are also bent to form opposing walls, so that the chip-shaped resistor 205 is formed between these opposing walls 227. Is inserted. The connection between the terminal 206 of the chip-shaped resistor 205 and the terminal connecting portion 226 can be made by welding such as laser welding, like the chip-shaped LED 202. If the chip type LED 202 and the chip type resistor 205 are attached to the same side of the connection conductor structure 204, the manufacturing apparatus is simplified and preferable because the laser only needs to be touched on one side. In addition, in FIG. 45, although the LED 202 and the resistor 205 of the left end are shown apart from the connection conductor structure 204 formed by cutting out the required part of the patterned conductor 200 for description, LED is actually shown. After the 202 and the resistor 205 are bonded to the patterned conductor 200 by welding, the required portions of the patterned conductor 200 (the branch portions 213 and 214) are cut off to form a connection conductor structure. As a result, each part of the connection conductor structure 204 may not be scattered. As another method, the insulating sheets 184 and 184 'are attached to the patterned conductors 200, for example, as shown in Figs. 35 and 36 so that the respective portions of the connection conductor structure 204 are not scattered, and then patterned. The required portion of the conductor 200 may be cut off.

In addition, the convex curved portions 211A and 212A of the first and second trunk path portions 211 and 212 of the tape-shaped patterned conductor 200 have a main surface of the light source connecting member 201 at its root portion. Bent almost vertically. As shown in FIG. 45, the curved convex curved parts 211A and 212A are strongly received in the corresponding grooves 231 formed in the flexible holder 230, for example, so that the light source connector ( The light emitting device 240 can be formed by attaching the holder 20 to the holder 230.

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 connection conductor structure 204 is not shown. As shown in FIG. 46, since each pair of terminals 203 are arranged along the width direction of the light emitting device 240, the LEDs 202 are arranged even when the light emitting device 240 is bent in the longitudinal direction. It will be appreciated that no force is generated, such as separating the terminal 203 of 202 and the terminal connector 216 of the connecting conductor structure 204.

Each light source attaching portion 265 has a pair of terminal connecting portions 266 corresponding to a pair of terminals of the chip type LED 252, and the resistor attaching portion 275 is similarly connected to a pair of terminals of the resistor 255. It has a pair of terminal connection part 276 corresponding. In this embodiment, between the adjacent light source attachment portion 265 and the resistance attachment portion 275 in the series block are connected by the contact path portion 260 and between the adjacent light source attachment portions 265 included in the other series block. Is presegmented.

Similarly, each terminal connecting portion 276 of the resistor attaching portion 275 is provided with a projection 277 for positioning the resistor 255. These projections 267 and 277 form a cutout in the width direction at the terminal connecting portions 266 and 276 at a position matched to an end of the LED 252 or the resistor 255 to be attached, for example. With respect to the portion, the portions of the terminal connection portions 266 and 276 on the side opposite to the side where the LED 252 or the resistor 255 is attached can be suitably formed by raising them with a press (see Fig. 47B). By providing such projections 267 and 277, the LED 252 and the resistor 255 can be easily positioned on the patterned conductor 250. Thereafter, the LED 252 and the resistor 255 and the patterned conductor 250 are connected by, for example, laser welding, and then the required portion of the patterned conductor is cut off to form a connection conductor structure having the required circuit pattern ( The light source connector 251 can be formed by forming 254 (FIG. 47C).

Terminal connection parts 416 corresponding to the second LED chip included in 402 are connected to each other in the longitudinal direction. Therefore, the 1st connection path 421A and the 2nd connection path 421B are spaced apart in the width direction. Moreover, the 1st connection path 421A and the 2nd connection path 421B matched with each other in the longitudinal direction are connected by the branch part 422 in the width direction.

Moreover, the light source attachment part 415 and the communication path part 410 are pinched in the width direction, and the 1st and 2nd trunk path parts 411 and 412 extend in the longitudinal direction. These 1st and 2nd trunk path parts 411 and 412 are connected to the 1st and 2nd connection paths 421A and 421B by the branch parts 413 and 414 extending in the width direction, respectively. In the second path part 412, a pilot hole 418 is formed to enable handling in a sequential feed press (not shown). In this embodiment, the third trunk path portion 419 is provided on the outer side in the width direction of the first trunk portion 411, and is coupled to the first trunk portion 411 by the branch portion 420 extending in the width direction. have.

The required portion of the patterned conductor 400 having such a structure is cut off to form a connection conductor structure, and the 4-pole LED lamp 402 as a light source is attached to the corresponding light source attachment portion 415 and a resistance is provided at a predetermined position. By attaching to the light source connector 401 using the 4-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 cut off is shown by the diagonal line. In addition, the attached 4-pole LED lamp 402 and the chip-shaped resistor 405 are shown by dotted lines. 55 is a circuit diagram of the light source connector 401 thus formed. In this example, one circuit unit is formed by three four-pole LED lamps 402 and two resistors 405, and the first and second connection paths 421A and 421B are formed at one end of each circuit unit. ) Are simultaneously coupled to the first trunk section 411, one of the two resistors 405 at the other end is connected between the first connection path 421A and the third trunk section 419 The other of the two resistors 405 is connected between the second connection path 421B and the second path part 412. Note 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 path part 411, and the low voltage side is connected to the third path part 419 through the switch SW1, and then through the switch SW2. When the switch SW1 is closed, the LED chip (first LED chip) in the upper part of the figure of each four-pole LED lamp 402 emits light by connecting to the second path part 412. When the switch SW2 is closed, each four-pole LED lamp The LED chip (second LED chip) at the bottom of the figure of 402 can emit light. Therefore, when the light emission colors of the LED chip on the upper side of the LED 402 and the LED chip on the lower side are different, the 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 a light source attachment portion 515 arranged in a longitudinal direction for attaching a light source, and these light source attachment portions 515 are connected in the longitudinal direction by the communication path 510. have. Each light source attachment portion 515 has a pair of terminal connection portions 519 corresponding to a pair of terminals of the light source, and the pair of terminal connection portions 519 are spaced apart from each other in the longitudinal direction. In each terminal connecting portion 519, a cross-shaped hole 516 for inserting the lead wire 103 is formed in the case where the light source is, for example, the shell type LED 102 as shown in FIG. In the case of the chip-shaped LED 152 as shown in FIG. 31, the LED 152 can be attached to the terminal connecting portion 519 by only laser welding. The communication path part 510 has the some connection path 521 which connects the terminal connection parts 519 contained in the adjacent light source attachment part 515. As shown in FIG. It can also be said that a connecting piece is formed by one connection path 521 and a pair of terminal connection portions 519 connected thereto. A part of each connection path 521 has a bridge part 521A formed relatively narrow so that cutting is easy, and the terminal connection part 519 connected by the connection path 521 is cut by cutting this bridge part 521A. It is detachable. Moreover, the light source attachment part 515 and the communication path part 510 are pinched in the width direction, and the 1st and 2nd trunk path parts 511 and 512 are arrange | positioned at both sides of the patterned conductor 500. As shown in FIG. Each terminal connection portion 519 of each light source attachment portion 515 is connected to either one of the first trunk path portion 511 or the second trunk path portion 512 by a corresponding branch portion 513, 514, One of the pair of terminal connection portions 519 in each light source attachment portion 515 is connected to the first trunk path portion 511 and the other to the second trunk path portion 512. Of course, branching portions 513 and 514 may be provided so that each terminal connecting portion 519 is connected to both of the first and second trunk path portions 511 and 512.

In this embodiment, in order to facilitate and ensure the installation of a resistor having a pair of lead wires, such as the resistor 122 shown in FIG. A cross-shaped hole 523 for inserting the lead wire is formed. As shown by a dotted line in FIG. 56, the lead 522A of the resistor 522 is inserted into these holes 523 (preferably, laser welding), thereby providing the resistor 522 with the terminal connecting portion 519. It can be connected between the two path portions 512, or between adjacent terminal connecting portions 519 included in any adjacent light source attachment portions. When attaching the resistor 522, it goes without saying that the corresponding bridge portion 521A or branch portion 514 is cut off. In this embodiment, the bridge portion 521A has a width center in the connecting path 521 so that the bridge portion 521A or the branch portion 514 can be cut in the bridge portion 521A after the resistance 522 is connected. At the same time, the resistance mounting holes 523 are formed in an arrangement in which the resistor 522 and the bridge portion 521A or the branch portion 514 do not overlap when the resistor 522 is attached.

For example, in the connection conductor structure (FIG. 21) formed by secondary processing the tape-shaped patterned conductor 120 of FIG. 18 for serial connection of a light source, each terminal attachment part 109 and both path parts 111 and 112 are shown. The branch portions 113 and 114 connecting () are excised. Therefore, when the LED 102 (FIG. 16) is connected and the current flows to the LED 102 by such a connection conductor structure, the heat generated by it is not dissipated through the both path portions 111 and 112. , The ambient temperature of the LED 102 may be undesirably high. The secondary processing method of the patterned conductor 120 shown in FIG. 57 enables dissipation of heat through the paths 111 and 112 while connecting the LEDs in series, thereby preventing an undesired rise in the ambient temperature of the LED. will be. In addition, in FIG. 57, the same code | symbol is attached | subjected to the same place as FIG. 18, and detailed description is abbreviate | omitted.

As shown in FIG. 57, in this example, instead of cutting off the branch parts 113 and 114, the location shown by the oblique line of the trunk part 111 and 112 is cut off. As a result, the pair of terminal connecting portions 109 and 109 in each light source attaching portion 5 are electrically separated from each other, so that each terminal connecting portion 109 can be connected in series with the LED 102 (FIG. 16). Can remain connected to the trunk paths 111 and 112. Thus, in this embodiment, the heat generated when the current flows through the LEDs 102 is quickly dissipated from the trunk portions 111 and 112, so that the heat circulates around each of the LEDs 102, causing the temperature to rise undesirably. Can be prevented. In the illustrated example, each terminal connecting portion 109 is connected to both path portions 111 and 112, but 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 receiving a light source connector in a glass tube having light transmissivity, the inner diameter of the glass tube is small (for example, about 5 mm), and the width thereof. Patterned conductors with this narrow cross section must be used. Such a patterned conductor 550 is shown in Fig. 58A. The patterned conductor 550 has a terminal connection portion 569 for forming a light source attachment portion 565 for attaching a light source (not shown), and a communication path portion for communicating the light source attachment portion 565 in the longitudinal direction ( 560, a pair of trunk paths 561, 562 extending in the longitudinal direction by sandwiching the light source attachment portion 565 and the communication path portion 560 in the width direction, and the trunk path portion 561 with the light source attachment portion 565. 562 has a plurality of branch portions 563 and 564 extending in the width direction in contact with 562, which is the same as the above-described embodiment, but is characterized in that the narrow portions 561 and 562 have a narrow width. have. Therefore, although it is possible to accommodate in a glass tube with a small inner diameter, attaching an electrode pin for connection with an external power source such as the conductive pin 93 shown in FIG. It is difficult. FIG. 58B is an end conductor 570 for enabling electrode pins to be attached to the end portions of the narrow path portions 561 and 562 of the patterned conductor 550 as shown in FIG. 58A. The end conductor 570 is provided with a pair of narrow width portions 571 and 572 for connection with the trunk portions 561 and 562 of the patterned conductor 550, and a pair of narrow width portions 571 and 572. Each has a pair of wide widths 573 and 574 connected to each other. In each of the pair of wide width portions 573 and 574, holes 573A and 574A that can be used to attach the electrode pins are formed. The end conductor 570 is preferably a patterned conductor by the pair of narrow width portions 571, 572 being laser welded with the patterned conductor 550 superimposed with the corresponding trunk portions 561, 562. 550 is integrated. In addition, although the pair of wide width portions 573 and 574 of the end conductor 570 are connected to each other by the bridge portion 575, the bridge portion 575 is cut off and separated before use. Thus, by using the end conductor 570 having a pair of narrow width portions 571 and 572 and a pair of wide width portions 573 and 574, a patterned conductor having narrow narrow passage portions 561 and 562. It is possible to easily attach the electrode pin to 550 as well.

In the example shown in FIG. 36, each part of the connection conductor structure 104 obtained by the secondary processing of the patterned conductor 120 is prevented from being scattered, or the mechanical strength of the connection conductor structure 104 is raised to facilitate handling. For this purpose, the insulating sheet 184 'was attached to the surface on the side opposite to the light source device surface of the patterned conductor 120. However, as in the other embodiment 101a of the light source connector shown in Fig. 59, the insulating sheet 184 'is placed on the light source attaching surface of the patterned conductor 120 (connection conductor structure 104), for example. It may be pasted by heat welding or the like. In addition, in this figure, the same code | symbol is attached | subjected to the place similar to FIG. 36, and detailed description is abbreviate | omitted. As shown in the drawing, the opening 185 is formed at a predetermined position in the insulating sheet 184 ', and the terminal connection portion of the light source (LED) 2 and the patterned conductor 120 is formed. The connection with 109 is enabled. The opening 185 may be formed before or after the insulating sheet 184 'is pasted onto the patterned conductor 120, or may be formed by a method such as pressing or laser processing after pasting. By attaching the insulating sheet 184 'to the light source attaching surface of the patterned conductor 120 in this way, the part to which the power supply voltage is applied is not exposed to the light source attaching surface which is relatively easy for workers to reach, thereby improving safety. In addition, the insulating sheet 184 'reflects the light from the light source 102 to increase the lighting efficiency.

As described above, when the insulating sheets 184 and 184 'are used to prevent scattering of each part of the connecting conductor structure 104 formed by the secondary processing of the patterned conductor, the light source connecting member 101 obtained. It is preferable to attach to the holding body so as to supplement the mechanical strength of ', 101 " and 101a. Further, after attaching the light source 102 to the patterned conductor 120, the required portion is cut off to form the connecting conductor structure 104. ), It is not necessary to use a connecting member such as an insulating sheet 184 ', but since the mechanical strength of the light source connector is further lowered, the use of the retainer is more preferable. Fig. 60B is a cross-sectional view showing a state in which the light source connector is attached to the holder.

As shown in FIGS. 60A and 60B, the holder 580 has a groove 582 extending longitudinally in the center portion, and the side walls 583 and 583 of the groove have a light source connector 101b. Guide grooves 583A and 583A extending in a pair of opposed longitudinal directions corresponding to the pair of trunk passages 111 and 112 are formed. In this example, the light source connecting member 101b is formed using the patterned conductor 120 as shown in FIG. 18, but does not have a connecting member, and the lead wire 103 is formed by bending the extension part 117. Caulking is not performed, and the lead wire 103 is connected to the patterned conductor 120 by laser processing, and the bottom surface portion is almost flat (FIG. 60B). As shown in FIG. 60A, the light source is slided in the direction indicated by the arrow in the figure so as to sandwich the pair of trunk portions 111 and 112 of the light source connector 101b into the corresponding guide grooves 583A and 583A. The attachment body 101b can be easily attached to the holder 580. Subsequently, as shown in FIG. 60B, a cover member 585 made of an insulator is formed on the light source attaching surface of the light source connecting member 101b to prevent a portion to which a power supply voltage is applied or to prevent unwanted shorting by dust or the like. ) Is attached. The cover member 585 is provided with an opening in accordance with the position of the light source 102 in advance. As shown in FIG. 59, when the insulating sheet 184 'is attached to the light source attachment surface, the cover member 585 may be omitted.

61 is a cross-sectional view showing another embodiment of the holder. The light source connector 101b is the same as that shown in Figs. 60A and 60B. The holder 590 has grooves 592 and 596 extending in the longitudinal direction on both the upper and lower surfaces thereof, and has a substantially H-shaped cross section. Guide grooves 593A and 593A into which opposing side walls 593 and 593 and 597 and 597 of the grooves 592 and 596 are fitted with a pair of trunk portions 111 and 112 of the associated light source connector. And (597A, 597A) are formed. By using such a holding body 590, it is possible to attach the light source connecting body 101b to the upper and lower surfaces of the holding body 590, respectively, to irradiate light to both the upper side and the lower side.

As described above, the patterned conductors 120 and 200 according to the present invention are preferably formed by a sequential feed press, but can also be formed by photoetching. A preferred method of forming a patterned conductor by such photoetching to obtain a light source connector is shown in Figs. 62A to 62C. As shown in FIG. 62A, for example, the heat-sealing sheet 603 is sandwiched between an electrically conductive plate 601 made of adjacent bronze and an insulating plate 602 of approximately the same size, and pressed at a high temperature to form the conductive plate 601. ) Is attached to the insulating plate 602. Subsequently, using port etching, patterned conductors 604-1, 604-2, ..., 604-N of a plurality of devices each having a pattern as shown in FIG. 56 are formed, for example. In addition, in FIG. 62B, the detailed illustration of the pattern formed is abbreviate | omitted. Apart from the photo-etching process, a hole drilling for inserting a light source or a lead of resistance may be performed by press working or the like. In this state, the plurality of patterned conductors 604-1, 604-2,..., 604-N are all attached to the insulating plate 602. Thereafter, for example, by pressing, appropriate portions of the patterned conductors 604-1, 604-2, ..., 604-N are cut off to form a desired connection conductor structure, as shown in Fig. 62C. A light source 606 (and a resistor if necessary) is attached to the connection conductor structure to form light source connectors 605-1, 605-2, ..., 605-N. In FIG. 62C, it can be seen that the surface light source is formed by the plurality of light source connectors 605-1, 605-2,..., 605 -N connected by the insulating plate 602. It is also possible, of course, to separate the light source connectors (connecting conductor structures) 605-1, 605-2, ..., 605-N from each other by cutting the insulating plate 602 after or before the light source 606 is attached. .

In the above embodiment, light source connectors 101, 101 ', 101 ", 201, etc., in which a plurality of light sources are arranged in a line, are formed using the patterned conductors 120, 200, etc. However, a plurality of light sources are included. A patterned conductor for forming a light source connector is also possible, Fig. 63A is a partial plan view showing an embodiment of a patterned conductor capable of forming a light source connector including, for example, two rows of light sources. As such, the patterned conductor 610 is formed by connecting two patterned conductors (patterned conductors for alignment of light sources) in two width directions to form a light source connector in which light sources are arranged in a row as described above. In detail, the patterned conductor 610 for arranging the light sources 102 is arranged so that the first to third trunk path portions 611, 612, and 613 for power supply connection are extended in parallel in the longitudinal direction. In the center of the second main passage 612 in the sequential feed press A pilot hole 614 is formed to facilitate positioning. A plurality of light source attachment portions 615 are disposed in the longitudinal direction between the first path portion 611 and the second path portion 612. Each light source attachment portion 615 is connected to the first trunk path portion 611 and the second trunk path portion 612 by corresponding branch portions 616 and 617 extending in the width direction and adjacent to the light source attachment portion 615. ) Are connected to each other by a communication path 618. Similarly, a plurality of light source attachment portions 625 are also arranged in the longitudinal direction between the second trunk path portion 612 and the third trunk path portion 613, The light source attachment portion 625 is connected by the contact path portion 628 in the longitudinal direction, and each light source attachment portion 625 is connected to the second path portion 612 and the third path by the corresponding branch portions 626 and 627 extending in the width direction. Connected to the unit 613. In this embodiment, the second center in the center is formed by two patterned conductors for arranging light sources in a row, respectively. It can be said that the trunk path part 612 is shared. Each light source attachment part 615 arranged between the first trunk path part 611 and the second trunk path part 612 is connected to a pair of terminals of a corresponding light source. A pair of terminal connecting portions 619, 619, each pair of terminal connecting portions 619, 619 are connected to each other by two bridge portions 619A, 619A in this embodiment, so that the light source is connected. Previously, these bridge portions 619A and 619A are cut off so that the pair of terminal connecting portions 619 and 619 in each light source attachment portion 615 are separated from each other. Each terminal connection portion 619 is provided with a hole 620 for inserting the lead wire when the light source has a lead wire. Similarly, each light source attaching portion 625 arranged between the second narrow passage portion 611 and the third narrow passage portion 613 has a pair of terminal connection portions 629, 629 corresponding to the pair of terminals of the corresponding light source. ), And each pair of terminal connection parts 629 and 629 are connected to each other by two bridge parts 629A and 629A in this embodiment. Each terminal connection portion 629 is formed with a hole 630 for inserting the lead wire when the light source has a lead wire.

FIG. 63B is a diagram illustrating an example of secondary processing tips of the patterned conductor 610 of FIG. 63A. In this figure, the light source 635 and the resistance 636 attached are shown by the dotted line, and the part to be excised is shown by the diagonal line. The light source 635 and the resistor 636 may be the same as the LED 102 and the resistor 122 shown in FIG. 16 and may have a lead wire, but may be a chip type having no lead wire. In addition, the polarity of the applied power voltage is indicated by a symbol. In this example, the patterned conductor 610 is secondary processed so that each column of the light sources 635 forms a light source serial parallel body in which a plurality of serial blocks each including four light sources 635 are connected in parallel. Will be understood. Of course, it is also possible to secondary process the patterned conductors 610 so that the light sources 635 in each row are connected in series or in parallel.

64 is a plan view showing an embodiment of a patterned conductor in which light sources can be arranged in four rows; The patterned conductor 640 has a configuration in which two patterned conductors shown in Fig. 63A are connected in the width direction. It will be understood that it is possible. As described above, according to the present invention, it is possible to arrange a plurality of rows of light sources, and to connect the light sources in various forms such as parallel, series, and serial parallel in each row of light sources by changing the ablation portion in the secondary processing. Possible patterned conductors are provided.

Since LEDs have the advantage of low power consumption and long life, it is proposed to use a plurality of LEDs as a light source and form a signal lamp. When the LEDs are connected in series or in parallel, if one LED fails and no current flows, the current does not flow in the LEDs connected in series with the LEDs, and the brightness of the entire signal lamp is greatly reduced. It is known to form a matrix circuit by connecting a plurality of LEDs in parallel and thereby connecting a plurality of parallel connecting bodies in series (for example, JP-A-4-8454). In such a circuit, even if one LED fails and no current flows, the current connected to the LED connected in parallel can flow current, so that the amount of light does not drop significantly. However, in such a circuit, when one LED causes a short circuit, both ends of each LED connected in parallel with the LED are short-circuited and light is not emitted from these LEDs. This greatly decreases. Fig. 65 is a schematic diagram showing an LED circuit suitable for a signal lamp capable of preventing a significant drop in the total amount of light even in the case of such a short circuit failure of the LED.

In the LED circuit 650 of FIG. 65, eight light source parallel connectors 652 to which five LEDs 651 are connected in parallel are connected in series, and the matrix circuit is similar to the conventional one. Each LED 651 has a feature in that an associated resistor 653 is connected in series. Accordingly, even if one LED 651 is short-circuited, voltage is generated at both ends of the resistor 653 connected in series with the LED 651, so that the other connected in parallel with the LED 651 is generated. Both ends of the LED 651 are not shorted, and light emission is maintained. Therefore, even if short circuit solidification of one LED 651 occurs, it is possible to prevent a significant decrease in the total amount of light. In addition, the number of LEDs 651 connected in parallel and the number of light source parallel connectors 652 connected in series can be arbitrarily changed.

As shown in FIG. 66, similar to the LED circuit 650 shown in FIG. 65, a plurality of light source parallel connection bodies 662 are connected in series so that a separate LED circuit having a circuit configuration in which the light source 661 is connected in a matrix form ( It is also possible to configure the light emitting device 670 by adding 660 and connecting them to independent power supplies (first power supply and second power supply) and arranging the light sources 651 and 661 to substantially overlap each other. By using two circuits 650 and 660 connected to separate power sources in this way, the minimum required brightness can be maintained even if one power supply fails.

As shown in FIG. 67, the light emitting device 670 having the circuit configuration as shown in FIG. 66 can be easily formed by using the light source connector 671 formed using the patterned conductor according to the present invention. There is a number. The light emitting device 670 of FIG. 67 includes a plurality of light source connectors 671 arranged in the width direction, and the light source connectors 671 connected to other power sources (the first power source and the second power source) alternately have widths. It is arranged in the direction. The LEDs included in each light source connector 671 are connected in parallel to each other between a pair of trunk paths 672 and 673 extending in the longitudinal direction, and each LED is connected to one trunk path 673 through a resistor. It is. Such a light source connecting body can be easily formed by, for example, secondary processing the patterned conductor 500 shown in FIG. 56 to cut off required parts and to connect LEDs as light sources. Each of the light source connectors 671 is contacted by jumper wires 675 and 676 to form two matrix LED circuits as shown in FIG. 65, so that the light source connectors 671 positioned at both ends thereof are formed. It is connected to the 1st power supply or the 2nd power supply. In this way, a highly reliable surface light emitting device suitable for a traffic light can be formed by using a light source connecting member 671 formed using a patterned conductor 500 or the like.

FIG. 68 schematically shows another embodiment of a light source connecting body according to the present invention having a plurality of light sources electrically connected to each other in a matrix shape and arranged in a line in space as shown in FIG. Partial plan view. In this figure, the direction of attachment of each LED is indicated by a symbol. This light source connecting body can also be formed by using a connecting conductor structure formed by cutting off a required portion of the patterned conductor 500 shown in FIG. In this figure, the same code | symbol is attached | subjected to the same part as FIG. 56, and detailed description is abbreviate | omitted.

The light source connector 700 has a plurality of LEDs 701 as light sources arranged in one row in the longitudinal direction as in the above embodiment, and in this embodiment, three LEDs 701 connected in parallel to each other are provided. A plurality of light source parallel connecting bodies to be included are connected in series. Of course, the number of LEDs 701 included in each parallel connection is not limited to three, but may include a separate number of LEDs 701. As in the above embodiment, the light source connector 700 also has first and second intermittent portions 511 and 512 sandwiching the LEDs 701 and extending in the longitudinal direction, and each LED 701 has these intermittent portions. Although connected through the branch part 513 and the resistor 702 which concern between 511 and 512, the direction of the LED 701 contained in the adjacent parallel connection body is reversed, and the 1st and 2nd path | route is also carried out. A part of the sections 511 and 512 is cut off from the above embodiment. As a result, when a direct current voltage is applied with the same polarity as the symbol, current flows from the left to the right in the drawing. As understood from the figure, the directions of the LEDs 701 included in the adjacent parallel connectors are reversed, so that the cathode and the downstream side of the LEDs 701 included in the parallel connectors on the upstream side of the adjacent parallel connectors are reversed. The anode of the LED 701 included in the parallel connector is connected. In addition, the first and second trunk paths 511 and 512 include an anode of the LED 701 included in the upstream parallel connector among the adjacent parallel connectors and a cathode of the LED 701 included in the downstream parallel connector. Are cut between the adjacent parallel connection bodies so as not to be separated or to short-circuit both ends of each LED 701 (symbols 703 and 704). Thus, according to this embodiment, it has a circuit structure which connected the parallel connection body including several light source 701 connected in parallel, respectively, and obtained the linear light-emitting body in which these light source 701 was arranged in linear form. Can be.

FIG. 75 is a schematic partial plan view showing a light source connection body in which a light source is connected in a matrix form, formed using a patterned conductor 610 suitable for arranging light sources such as those shown in FIG. 63A in two rows. In this figure, the same code | symbol is attached | subjected to the same place as FIG. 63A, and detailed description is abbreviate | omitted. In addition, the LED is indicated by the symbol so that the connection direction is known. In FIG. 75, the patterned conductor 610 is already shown to have cut off the required portion (that is, as a connected conductor structure). Each LED 721 is connected between the first path part 611 and the second path part 612 or the second path part 612 and the second path part through corresponding branch parts 616 and 626 and a resistor 722.

In this example, a red light source connector 731 including a plurality of red LEDs (R), a green light source connector 732 including a plurality of green LEDs (G), and a plurality of blue LEDs (B) The surface light emitting device 730 having a circular light emitting surface is formed by using the blue light source connector 733. As shown, these three light source connectors 731, 732 and 733 are vortexed toward the center at each of the viewpoints RS, GS and BS spaced at approximately equal intervals in the circumferential direction at the peripheral edge of the light emitting surface. It is arranged to form a shape. This makes it possible to emit light of each color almost circularly with the same brightness. 77 shows an embodiment in which the square surface light emitting device 730a is formed using the same method. The shape of the surface light-emitting body thus formed can be arbitrarily selected. In addition, in the above embodiment, one light source connector is used for each color, but for example, two light source connectors are used for each color, so that the light source assembly is vortexed at a total of six viewpoints. It is also possible to arrange toward. It is also possible to use a light source (LED) of not only three colors but more than two colors or more than three colors. Of course, it is also possible to make the emission color of the light source included in the all-light source connector the same.

78 is a schematic diagram showing another embodiment in which the surface light emitting device is formed using a plurality of light source connectors formed according to the present invention. As shown, in this surface light emitting device 740, a plurality of red, blue, and green light source connectors are arranged in a concentric circle shape. It will be appreciated that this arrangement, like the embodiment above, is not limited to a prototype.

Fig. 79 is a schematic diagram showing an example of the use of a light source connecting body (for example, the light source connecting body 101 " shown in Fig. 36) according to the present invention. Since the light source connector according to the present invention is flexible, it is possible to twist and use it as shown in the drawing, whereby the light source 102 is arranged almost in a spiral shape, so that the surrounding space is made almost evenly. It is possible to illuminate.

By the way, since LEDs have extremely long life compared with incandescent lamps, in recent years, LEDs have been used as light sources for so-called on-vehicle lamps such as stop lamps, tail lamps, and direction indicators of automobiles that require high reliability. Such a vehicle lamp needs to have a three-dimensional structure to fit the overall shape of the vehicle body, for example, to be installed at a corner of the vehicle body, and the LED as a light source must also be three-dimensionally arranged in accordance with it.

An on-vehicle lamp having such a three-dimensionally arranged LED is disclosed, for example, in JP-A-11-121807. The on-vehicle lamp disclosed in this publication has a light emitting unit having a plurality of LEDs, a paste having a plurality of stepped end portions, and a holder fitted to and supported by the plurality of end portions to hold corresponding LEDs. This light emitting unit is housed in a lamp chamber defined by the lens and the lamp body. An electrical cord is sandwiched between the LED and the holder, whereby the electrical connection of the LED is made. In addition, the lead wire of each LED is provided with a slit of a width substantially corresponding to the diameter of the core wire so that the covering of the electric cord can be peeled off and the core wire of the cord can be exposed when the LED is attached to the holder. In addition, each holder is provided with an electric cord insertion groove for temporarily holding an electric cord before attaching the LED.

In such a vehicle lamp, the holder is attached to the base and fixed, the electric cord is passed through the insertion through groove of the holder, and then the LED is inserted into the holder to sandwich the electric cord between the LED and the holder, thereby emitting light as a main component of the luminaire. Units can be formed. In addition, as a separate method, the holder is separated from the base, and the light source is formed by first holding the electric cord and the LED in the holder, and then attaching the holder to the base to fix the light emitting unit. It may be.

However, in such on-vehicle lamps, there is a problem that the number of parts increases due to the holder being separated from the base, and the management cost and manufacturing cost increase. If the holder is integrated with the base, the shape of the base becomes complicated and the mold value of the base rises. In addition, even in the above-described disassembly assembly process, it is very difficult to automate because the electric cord needs to be passed through the insertion through groove of the individual holder. In addition, the fact that the lead cannot use a commercially available product using an LED having a special shape is one cause of the increase in manufacturing cost.

Fig. 80 is a perspective view of one embodiment of an on-vehicle lamp light emitting device using a light source connecting body according to the present invention to solve the above problems. As shown, this light emitting device 800 has a plurality of LEDs 802 as light sources (9 in this example) and a plurality of ends stepped to three-dimensionally arrange these LEDs 802. It has a base (retainer) 830. Such a light emitting device 800 is used 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 related art. In this embodiment, each LED 802 has a plate-shaped anode terminal 803a and a cathode terminal 803b.

In this embodiment, three LEDs 802 are connected in parallel to form one light source connector 801, such a light source connector 801 is connected in series with three jumper members 815, so-called A matrix circuit (or parallel series circuit) is formed. In this example, the adjacent light source connectors 801 are connected by one jumper member 815 at their ends, but two or more jumpers at a plurality of locations for reducing electrical resistance and improving heat transfer characteristics. The member 815 may be connected, and the number is arbitrary. In the illustrated example, the jumper member 815 is formed by bending a flat conductor at an appropriate location. However, a coated conductor or the like may be used.

FIG. 81: is a perspective view which shows the light source connector 801 before bending to match the shape of the base 830, and FIG. 82 is sectional drawing. As shown, the light source connector 801 has a connection conductor structure 804 for electrically connecting a plurality of (three in this example) LEDs 802. The connecting conductor structure 804 has a pair of conductors (segments) 811 and 812 extending substantially parallel to the longitudinal direction, and the anode terminal 803a and the cathode terminal 803b of each LED 802 are respectively The corresponding trunk portions 811 and 812 are preferably attached and fixed by welding, such as laser welding. That is, in this embodiment, it can be said that the pair of trunk portions 811 and 812 include a light source attachment portion (or a light source terminal connecting portion).

In this embodiment, the width of the path part 812 to which the cathode terminal 803b of each LED 802 is attached is wider than that of the path part 811 to which the anode terminal 803a is attached, so that heat can be more easily conducted. It is. Normally, an LED chip (not shown) plugged and sealed in the LED package in each LED 802 is directly attached to the plate-shaped cathode terminal 803b, and the anode terminal 803a is connected by a lead wire or the like. Since most of the heat generated from the LED chip is emitted to the outside through the cathode terminal 803b, the width of the path portion 812 to which the cathode terminal 803b is connected in this way increases the width from the LED 802. Dissipation of heat can be made more efficient. In addition, the width of the light source connecting member 801 can be reduced by narrowing the width of the trunk portion 811 to which the anode terminal 803a to which the contribution to heat radiation is small is connected.

The light source connector 801 is a tape-shaped patterned conductor having a predetermined pattern, as shown in the above-described embodiment, the LED 802 is attached to a suitable position, then the required portion of the patterned conductor is cut off the LED ( It is obtained by forming the connection conductor structure 804 which connects 802 in parallel. 83 is a partial plan view of one embodiment of a patterned conductor suitable for forming a light source connector 801 having such parallel-connected LEDs 802.

As shown in the drawing, the patterned conductor 820 has a tape shape that is a flat plate, and a pair of conductors (segments) 811 and 812 extending in the longitudinal direction, and the paths 811 and 812. It has a some branch part 813 connected to the width direction. As described above, the trunk path portion 812 to which the cathode terminal 803b of the LED 802 is attached is wider than the trunk path portion 811 to which the anode terminal 803a is attached. In addition, in each trunk part 811, 812, the some pilot hole 818 which can be used for conveyance / positioning by a sequential feed press (not shown) etc. is provided in the longitudinal direction at predetermined intervals.

The LED 802 is attached between the pair of trunk paths 811, 812 of the patterned conductor 820, for example, by laser welding, and then connected between the pair of trunk paths 811, 812. By cutting off the branch portion 813 and cutting the patterned conductor 820 to a more suitable length, it is possible to form the light source connector 801 having any number of parallel-connected LEDs 802. Before attaching the LED 802, since the pair of trunk portions 811 and 812 are mechanically connected by the branch portion 813, the handling of the patterned conductor 820 is easy, and accordingly, The operation of attaching the LED 802 to the patterned conductor 820 as described above, cutting the branch portion 813 of the patterned conductor 820, and cutting the trunk portions 811 and 812 are sequentially performed. It is possible to improve the production efficiency by automating to one manufacturing line including. In addition, by attaching the LED 802 to the patterned conductor 820 by laser welding without using a special holder, it is possible to reduce the number of parts and to reduce the management cost.

81 is formed by bending the light source connecting member 801 as shown in FIG. 81 at a predetermined position and attaching it to the base 830 to form the on-vehicle lamp light emitting device 800 as shown in FIG. There is a number. The attachment of the light source connecting member 801 to the base 830 is provided with a boss portion (not shown) at a predetermined position of the base 830, for example, and the path of the light source connecting member 801 is separated from these boss portions. The pilot holes 818 provided in the sections 811 and 812 can be inserted or an adhesive may be used.

When attaching the light source connector 801 to the base 830, it is preferable that each LED 802 is disposed at an appropriate position on the base 830. For example, in bending the light source connector 801, When the precision of is low, it may shift from an appropriate position. In such cases, it is desirable to be able to adjust the position of the LEDs 802 such that each LED 802 is positioned at an appropriate position. In the above example, the LEDs 802 included in the light source connectors 801 are arranged in a straight line, but there are cases where it is desirable to offset or bend the arrangement direction of the LEDs 802. 84A is a partial plan view of another embodiment of a patterned conductor that enables adjustment of such an LED position. 84B is the same figure as FIG. 84A which showed the part which cut | disconnected in the use state by oblique line. In addition, in these drawings, the same code | symbol is attached | subjected to the place similar to FIG. 83, and detailed description is abbreviate | omitted.

In the patterned conductor 820 'shown in FIG. 84A, stretchable portions 821 are formed at predetermined positions in the longitudinal direction of the pair of trunk portions 811 and 812, respectively, and these stretchable portions 821 are formed. The position of the LED can be adjusted by the. Preferably, the stretchable portion 821 is formed between adjacent LED attachment positions. In addition, although the width | variety of the pair of trunk path parts 811 and 812 was the same in FIG. 84A, it is also possible to make it have a different width like the Example shown in FIG.

In the embodiment of Figs. 84A and 84B, each of the flexible portions 821 includes a pair of nearly U-shaped thin connection paths 822 formed in each of the trunk portions 811 and 812, and each of the U-shaped connection paths. A pair of straight portions facing 822 extend in the substantially width direction of the trunk portions 811, 812, and the bent bottom edge portion is located on the center axis side of the patterned conductor 820 '. In addition, the stretchable portion 821 has a bridge portion 823 extending in the longitudinal direction at the end portions in the width direction of the trunk portions 811 and 812 so as to connect both ends of each U-shaped connecting passage 822. As a result, deformation of the stretchable portion 821 is normally prevented, and the bridge portion 823 acts as a deformation preventing portion. In use, as shown by the oblique line in FIG. 84B, the desired stretchable portion 821 can be deformed by cutting off the bridge portion 823. By using the bridge portion 823 as described above, the stretchable portion 821 can be selectively deformed only in necessary portions so that the LED arrangement position can be adjusted, and the mechanical strength of the entire light source connector formed is unnecessary. The fall can be prevented. In addition, since the rigidity of the patterned conductor 820 'or the light source connecting body formed using the same is relatively high in the state before removing the bridge part 822, handling thereof is easy. The stretchable portion 821 and the bridge portion 823 of the patterned conductor 820 'can be easily and inexpensively formed by blanking of the press working.

85A and 85B are partial plan views showing an example of a deformation state of the light source connecting member 801 'formed using the patterned conductor 820' shown in FIG. 84A. In Fig. 85A, the arrangement direction of the LED 802 (or the longitudinal axis of the light source connector 801 ') is changed to the patterned conductor 820' by the deformation of the two stretchable portions 821 in the longitudinal direction. Or bent in a plane parallel to the main surface of the connecting conductor structure 804, and as a result, the arrangement direction of the LEDs 802 is offset in the width direction (horizontal direction) at the right end and the left end of the figure. In FIG. 85B, the stretchable portion 821 is deformed so that the distance between adjacent LEDs 802 is widened in the longitudinal direction of the light source connector 801 '. As described above, in the light source connector 801 'using the patterned conductor 820' having the stretchable portion 821, the arrangement position of the LED 802 is adjusted to ensure that the LED 802 is positioned at an appropriate position on the base. Not only can it be arranged, but also various LED arrangements can be easily performed, and the design freedom of the shape of the on-vehicle lamp can be greatly improved. Alternatively, for the other base, the same light source connector 801 'can be used as long as the difference can be absorbed by the deformation of the stretchable portion 821 of the light source connector 801'.

For the same reason as described above, the area of the trunk portion 852 is larger than that of the trunk portion 851. In addition, each of the trunk portions 851 and 852 is provided with a plurality of pilot holes 858 which can be used for conveyance / positioning by a sequential feed press (not shown) or the like at predetermined intervals in the longitudinal direction.

In the patterned conductor 850, the gap 855 between the pair of trunk paths 851 and 852 is bent in a square wave shape instead of a straight line shape. Alternatively, irregularities are alternately formed in the longitudinal direction on the sides adjacent to each of the trunk portions 851 and 852, and the convex portions formed on the other side enter the recesses formed on one side of the trunk portions 851 and 852 in the longitudinal direction. It may also be said that they are arranged in a match. This structure makes it possible to shift the pair of trunk portions 851 and 852 with respect to each other, and to adjust the gaps not only in the width direction but also in the longitudinal direction. In addition, the patterned conductor 850 as described above can be easily formed by pressing a flat plate conductor.

FIG. 89B is a plan view of a light source connector formed using the patterned conductor 850 of FIG. 89A. In this figure, the LED is typically represented by a symbol so that the attachment direction is known. The light source connecting member 860 attaches the LED 861 to the patterned conductor 850 by, for example, laser welding, and then, in the width direction and the length of the pair of the trunk paths 851 and 852. It adjusts to a direction and forms by cutting out the trunk part 853. As shown, in this embodiment, the gap between the pair of trunk portions 851 and 852 of the patterned conductor 850 is non-linear and has a portion extending in the width direction, whereby the LED 861 Can be largely adjusted not only in the longitudinal direction but also in the transverse direction (width direction). Accordingly, it is possible to form a light source connector 860 having various LED array patterns using the same patterned conductor 850, for example, to form a vehicle lamp using the light source connector 860. In this case, it is possible to cope with a case where a different LED array pattern is required by the vehicle model, and the economical use of components can be achieved, and a great economic advantage can be obtained.

As described above, according to the present invention, since various light source connectors having different light source connection patterns can be manufactured in the same manufacturing line from a patterned conductor in which a predetermined circuit pattern which can be commonly used is formed in advance, it is possible to improve productivity. A great effect can be obtained in reducing costs. In addition, since there is no need to use a printed board, and the solder used for connection with the printed board can be made unnecessary, there is no need to worry about environmental pollution, and there is also no fear of damaging the LED due to heat when using the solder.

Although this invention was demonstrated in detail according to an Example, these Examples are an illustration to the last and this invention is not limited by an Example. It goes without saying that those skilled in the art can make various modifications or changes without departing from the technical spirit of the present invention defined by the claims. For example, in the embodiment of FIGS. 16 and 29, the connecting members 115 and 165 are formed by insert molds, but the molded members are divided into upper and lower parts and patterned conductors 120 and 170 are formed therebetween. It is also possible to form by attaching to each other with an adhesive or the like while sandwiching. In addition, although LED was used as a light source, it is also possible to apply this invention to another light source (for example, an electronic device without an entrance).
