Description

  The present invention relates to a light-emitting device holder for fixing a light-emitting device having a light-emitting element on a substrate surface to an attachment target.

  In recent years, LEDs have been used as light sources for lighting bulbs, street lamps, automobile lighting, and the like in the general lighting field as luminous efficiency is improved. In such a general LED lighting device, a light emitting diode package (light emitting device) having a high output type structure (Chip on Board) may be used. Specifically, in this light emitting device, a conductor wiring is formed on a substrate such as ceramics, a plurality of light emitting elements (hereinafter referred to as “LED chips” as appropriate) are mounted thereon, and a phosphor is disposed around the LED chip. The structure sealed with the contained silicone resin etc. is provided. At this time, the electrical connection terminals of the light emitting device are often arranged on the upper surface side (light emitting surface side) of the substrate.

  As a method of fixing the power supply of the light emitting device having such a configuration to the attachment target, there is a case where a method of fixing the power supply of the light emitting device to the attachment target using a light emitting device holder (hereinafter referred to as “holder” as appropriate) may be used. . For example, an opening that avoids the light source part of the light-emitting device is formed in the holder, a terminal that is an electrical wiring for electrically connecting the external power source and the light-emitting device is provided inside the holder, and the holder is covered from above the light-emitting device. By disposing the cover, the external power supply and the light emitting device can be electrically connected.

  However, as described above, when the holder is covered with the light emitting device and electrical connection is made by the terminals arranged inside the holder, the holder is covered with the light emitting device, so that there is a gap between the holder and the light emitting device. It will occur. Here, since the holder is mainly made of an engineer plastic such as a liquid crystal polymer, the holder itself has an insulating property. On the other hand, since the terminal needs to be electrically connected to the light emitting device, metal is used, and the terminal is exposed from a part of the holder and connected to the light emitting device.

  At this time, the mounting target of the light emitting device is specifically a heat sink, and a metal member such as aluminum is used in consideration of heat dissipation. Since such a heat sink is not necessarily subjected to an insulation treatment capable of withstanding a high voltage, if the insulation treatment is not carried out, a gap formed between the holder and the light emitting device described above is used. There is a problem that an electrical short circuit occurs between the terminal in the holder and the heat sink.

  Further, in order to avoid a short circuit at the above-described location, when trying to provide a creepage distance between the heat sink and the terminal, the shape of the holder itself is increased, and the terminal inside the holder is made of an insulating member. Since it is necessary to conceal the exposed portion of the terminal, for example, by placing it in a deep part of the holder, the holder itself becomes large, and as a result, there is a problem that it interferes with a secondary optical system, a lighting fixture, or the like.

  Here, for example, Patent Document 1 proposes a holder (connecting element) having a contact element that comes into contact with an electrode of a light emitting device as a holder for fixing the light emitting device to an attachment target. It is described that a connection without soldering can be made possible. In the technique proposed in Patent Document 1, the light emitting device is fixed to an attachment target by a holder. In other words, LEDs are arranged on a star-shaped substrate (it is not a COB as described above, but it is regarded as a structure equivalent to COB because there is a light emitting portion and an electrical connection portion on the substrate), and the electrical connection on the star-shaped substrate The portion is configured to be electrically connected to an external power source by pressing a terminal exposed from the holder. Further, the technique proposed in Patent Document 1 has a structure in which the terminals are arranged in the upper surface direction of the star-shaped substrate when the light emitting surface side is the upper surface, and withstand voltage performance by providing a creepage distance from the mounting target. It has a structure to prevent short circuit.

JP 2009-176733 A

  However, the technique proposed in Patent Document 1 has a problem that the holder shape becomes large by providing a creepage distance from the attachment target. In addition, when trying to provide a creepage distance without increasing the holder shape, while maintaining the positional relationship that does not protrude from the outer shape of the light emitting device, the terminal is extended to the light emitting surface side to make an electrical connection with an external power source, After extending the terminal to the light emitting surface side according to the positional relationship, it is necessary to devise such as arranging the terminal inside the holder at a position where the creeping distance is secured. However, in these cases, since the height of the holder shape becomes large, there is a problem that the radiation emitted from the light emitting device is blocked by the holder and the directivity is narrowed.

  The present invention has been made in view of such problems, and provides a light emitting device holder capable of improving the insulation performance when the light emitting device is fixed to an attachment target without increasing the size of the holder. The issue is to provide.

  In order to solve the above-mentioned problems, a light-emitting device holder according to the present invention is a light-emitting device holder for holding a light-emitting device having a light-emitting element on a substrate surface and fixing the light-emitting device to an attachment target. A holder body provided with a first through hole formed so as to penetrate to a position facing the light emitting element, a second through hole in which a substrate of the light emitting device is accommodated, and an energization provided inside the holder body A terminal, and the holder main body has a wall portion formed so as to rise from the second through hole side to the first through hole side so as to surround the second through hole, It was set as the structure by which the terminal was provided inside the said holder main body across the said wall part.

  According to the holder for a light emitting device according to the present invention, by providing a wall portion between the energization terminal and the second through hole in the holder main body, the attachment target and the energization terminal are provided by the height of the wall portion. Since the creepage distance between the terminal and the energization terminal is increased, a short circuit is unlikely to occur. Therefore, according to the light-emitting device holder according to the present invention, it is possible to improve the insulation performance when the light-emitting device is fixed to an attachment target without increasing the size of the holder.

Moreover, in the following description, the same name and code | symbol are showing the same or the same member in principle, and a detailed description is abbreviate | omitted suitably.

[Configuration of holder for light emitting device]
As shown in FIG. 1, the light-emitting device holder 1 is for holding the light-emitting device 2 and fixing it to the attachment object 3. In addition, the holder 1 can supply power from the outside to the light emitting device 2 in a state where the light emitting device 2 is fixed to the attachment target 3. Here, the holder 1 includes an upper holder 11, a lower holder 12, and an energization terminal 13.

  As shown in FIG. 2A, the upper holder 11 and the lower holder 12 constitute a holder main body 10 by being fitted to each other. As will be described later, an energization terminal 13 is accommodated in the holder body 10. In addition, at the corner portion on one side of the holder body 10, a lead-out port 14 for connecting the internal energization terminal 13 to an external power source is provided. The lead-out port 14 is formed as a pair corresponding to the anode and the cathode. As shown in FIG. 2B, the drawer opening 14 is formed by locking the drawer side locking part 122 on the lower holder 12 side to the drawer side locked part 112 on the upper holder 11 side. Is. In FIG. 2B, for convenience of explanation, the configuration on the lower holder 12 side is highlighted with dot hatching.

  As shown in FIGS. 1 and 3A, the upper holder 11 has a plate shape and is configured to be positioned on the light emitting surface side (the upper side here) of the light emitting device 2. In the center of the upper holder 11, a through hole (first through hole) H1 penetrating the front surface and the back surface is formed. The through hole H <b> 1 is for exposing a light emitting portion composed of the light emitting element 22 of the light emitting device 2, and is formed at a position facing the light emitting element 22 of the light emitting device 2. Therefore, the shape of the through hole H1 is appropriately adjusted according to the shape of the light emitting part of the light emitting device 2 to be held. In the light emitting device 2 according to the present embodiment, since the light emitting part has a circular shape as shown in FIG. 1, the through hole H1 is also formed in a circular shape. In addition, when the light emission part of the light-emitting device 2 is rectangular shape, the through-hole H1 is also formed in a rectangular shape according to this.

  As shown in FIG. 1, the through hole H <b> 1 is formed so that the inner diameter becomes larger toward the surface side (upper side). By providing such a through hole H1, the upper holder 11 can emit light from the through hole H1 without blocking the light emitted from the light emitting device 2. The inner diameter of the through hole H1 may be increased linearly (that is, at a constant rate), or may be increased in a curved line (that is, the inner diameter varies depending on the position). Further, the inner diameter of the through hole H1 may be larger than the light emitting portion of the light emitting device 2 as long as the size of the holder 1 itself is allowed, as long as the emitted light is not blocked.

  As shown in FIG. 3A, the upper holder 11 is formed with a plurality (two in this case) of fixing holes T1 penetrating the front surface and the back surface. As shown in FIG. 1, the fixing hole T <b> 1 is where the screw member F is inserted when the fixing hole T <b> 1 is fixed to the attachment target 3.

  The surface of the upper holder 11 (including the periphery of the through hole H1) is desirably formed so as to have a high reflectance (formed so as to have reflection characteristics). For this reason, the surface of the upper holder 11 is subjected to reflection processing (mirror reflection processing, diffusion surface reflection processing) here. By performing such surface reflection processing on the upper holder 11, when the light emitting element 22 emits light in a state where the holder 1 is covered with the light emitting device 2, a lens provided in front of the surface of the upper holder 11. Even if a part of light is reflected by the optical element such as the above, the reflected light can be further reflected on the front surface of the upper holder 11.

  The reflectivity of the surface of the upper holder 11 (especially around the through hole H1) exhibits the effects as described above, so that the surface is subjected to specular reflection processing (aluminum deposition, etc.) or diffusion surface reflection processing (painting of a white reflection material, etc.) ) Is preferably set to 90% or more. Specifically, when it is not desired to diffuse light (when applied to a condensing lens or the like), it is preferable to perform aluminum vapor deposition on the surface of the upper holder 11 in order to reflect the light specularly. When it is desired to diffuse light, it is preferable to coat a white reflective material on the surface of the upper holder 11 in order to diffusely reflect the light. In addition, as reflection processing (specular reflection processing, diffusive surface reflection processing), in addition to the above-mentioned means, there is also a means of polishing a mold used when manufacturing the upper holder 11, and by this means, the upper holder 11 It can be formed so that the reflectance of the surface becomes high, that is, it can be formed smoothly.

  A plurality of locked portions to be locked to the lower holder 12 are formed on the side surface of the upper holder 11. That is, as shown in FIG. 1 and FIG. 3A, side-side locked portions 111 formed by cutting out the outer wall portion 113 in a concave shape are provided on the four sides of the upper holder 11. As shown in FIG. 2A, the side-side locked portion 111 is locked by a corresponding hook-shaped side-side locking portion 121 of the lower holder 12.

  At the corner portion of the upper holder 11, a drawer-side locked portion 112 formed by cutting out the outer wall portion 113 near the corner portion is provided. As shown in FIG. 2B, the drawer-side locked portion 112 is locked by the drawer-side locking portion 122 of the lower holder 12.

  As shown in FIG. 3A, a claw portion 114 that is used when holding the light emitting device 2 is formed on the back surface of the upper holder 11. The claw portion 114 is provided so as to protrude from the back surface of the upper holder 11. Further, as shown in FIG. 4A, four claw portions 114 are formed adjacent to the positioning portion 124 of the lower holder 12. Thereby, the claw part 114 can hold | maintain the light-emitting device 2 whole firmly by pinching | interposing the four corners of the board | substrate 21 of the light-emitting device 2, as shown in FIG.4 (b). Further, the claw portion 114 is integrated with the positioning portion 124 of the lower holder 12 and is disposed at a position where it can be inserted into the positioning hole T5 of the attachment target 3 (see FIG. 7D described later).

  On the back surface of the upper holder 11, as shown in FIGS. 3 (a) and 5, a terminal groove 115 is formed along the shape of the energizing terminal 13 (cathode side energizing terminal 13a and anode side energizing terminal 13b). The terminal 13 for electricity supply is attached in the said groove part 115 for terminals. Further, as shown in FIGS. 3A and 5, a wall groove 116 is formed on the back surface of the upper holder 11 in addition to the terminal groove 115. When the upper holder 11 and the lower holder 12 are fitted to each other, the wall groove 116 is inserted with a wall 125 described later (see FIG. 5). As shown in FIGS. 3A and 3B, the wall groove 116 is formed in the upper holder 11 in accordance with the position where the wall 125 of the lower holder 12 is formed.

  As shown in FIGS. 1 and 3B, the lower holder 12 has a plate shape and is configured to be positioned on the back side (here, the lower side) of the light emitting device 2. In the center of the lower holder 12, a through hole (second through hole) H2 penetrating the front surface and the back surface is formed. The through hole H2 is for housing the light emitting device 2, and is formed so that the substrate 21 of the light emitting device 2 can be accommodated. Therefore, the shape of the through hole H2 is appropriately adjusted depending on the shape of the substrate 21 of the light emitting device 2 to be held. In the light emitting device 2 according to the present embodiment, since the substrate 21 has a rectangular shape as shown in FIG. 1, the through hole H2 is also formed in a rectangular shape. In addition, since the lower holder 12 in which the through hole H2 is formed is fitted to the upper holder 11 in which the through hole H1 is formed, the through hole H2 and the through hole H1 are the vertical direction of the holder 1 here. It is in the state provided continuously so that it may become one through hole. In the present embodiment, the upper holder 11 and the lower holder 12 are described as being fitted separately, but at least the first through hole H1 of the upper holder 11 and the second through hole of the lower holder 12 are described. H2 may be a holder that forms one through hole, for example, an upper holder 11 that extends from the outer wall of the lower holder 12, and the upper holder 11 is bent upward and fitted, The upper holder 11 may have at least a first through hole H1 and is not exposed when viewed from the light emitting surface side. If it is.

  As shown in FIG. 3B, the lower holder 12 has a plurality (two in this case) of fixing holes T3 penetrating the front and back surfaces. As shown in FIG. 1, the fixing hole T <b> 3 is where the screw member F is inserted when the fixing hole T <b> 3 is fixed to the attachment target 3.

  As shown in FIGS. 1 and 3B, a wall portion 125 is formed around the through hole H <b> 2 in the lower holder 12 toward the upper holder 11. This wall part 125 is for preventing the short circuit between the terminal 13 for electricity conduction mentioned later and the attachment object 3. FIG. That is, as shown in FIG. 5, when the upper holder 11 and the lower holder 12 are fitted together, the wall portion 125 is formed so as to hide the exposure of the energizing terminal 13 described later. And function as an insulating wall between the object 3 and the mounting object 3.

  As shown in FIGS. 1 and 3B, the wall portion 125 is formed so as to rise from the second through hole H2 side to the first through hole H1 side so as to surround the through hole H2. Further, the wall portion 125 is formed to rise toward the upper holder 11 side (here, upward) on the lower holder 12 side. The wall 125 may be formed continuously connected to the periphery of the through hole H2, or may be partially formed around the through hole H2, but here, the through hole H2 excluding the corners. Are partially formed on each side.

  Here, the energizing terminal 13 to be described later is configured to be wired inside the holder body 10 and to be in contact with the connection pad 23 of the light emitting device 2 (see FIG. 7D). At that time, the energization terminal 13 routed around the inside of the holder body 10 is extended until it is exposed to the through hole H2, as shown in part C of FIG. Therefore, when the wall portion 125 is partially formed around the through hole H2 as shown in FIG. 3B, the wall portion 125 is a region where the short circuit is particularly likely to occur, and the energization terminal 13 passes therethrough. It is preferably formed mainly around the region exposed in the hole H2 (that is, the portion C in FIG. 4A).

  The height of the wall portion 125 is determined by the fitting state of the upper holder 11 and the lower holder 12, but it is preferable that the wall portion 125 is formed to a height that contacts at least the inner surface of the upper holder 11 on the lower holder 12 side. Thereby, exposure of the terminal 13 for electricity supply with respect to the attachment object 3 can be hidden completely.

  Moreover, the wall part 125 is fitted in the groove part 116 for walls formed in the inner surface of the upper holder 11, as shown in FIG. 5 which showed a part of BB sectional drawing of Fig.2 (a). It is preferable to be configured as above. Thereby, while being able to completely hide exposure of the terminal 13 for electricity supply with respect to the attachment object 3, the upper holder 11 and the lower holder 12 can be firmly fitted. A configuration in which the wall portion 125 penetrates the upper holder 11 and is exposed to the surface side is also conceivable. However, since this configuration impedes light emission reflection, the upper portion is formed as shown in FIG. It is preferable to provide the wall portion 125 up to a range where it is not exposed on the surface side of the holder 11.

  A plurality of locking portions for locking to the upper holder 11 are formed on the side surface of the lower holder 12. That is, as shown in FIG. 1 and FIG. 3B, hook-shaped side locking portions 121 formed so as to protrude on the outer wall portion 123 are provided on the four sides of the lower holder 12. As shown in FIG. 2A, the side-side locking portion 121 locks the corresponding side-side locked portion 111 of the upper holder 11.

  At the corner portion of the lower holder 12, a pull-out side locking portion 122 formed to protrude on the outer wall portion 123 near the corner portion is provided. As shown in FIG. 2 (b), the drawer-side locking portion 122 locks the drawer-side locked portion 112 of the upper holder 11. Here, the holder main body 10 has a structure in which the energizing terminal 13 is sandwiched between the upper holder 11 and the lower holder 12 and the upper holder 11 and the lower holder 12 are mechanically fitted in the vertical direction. There is a risk that the upper holder 11 and the lower holder 12 will be disengaged when the current-carrying wiring is inserted into the outlet 14 of the holder body 10. However, since the drawer-side locking portion 122 is provided, the upper-side holder 11 and the lower holder 12 are fitted to the drawer-side locked portion 112 of the upper holder 11 in the vertical direction and the horizontal direction. Is difficult to come off.

  As shown in FIG. 3B, a positioning portion 124 for positioning the holder 1 with respect to the attachment target 3 is formed on the back surface of the lower holder 12. The positioning portion 124 is provided so as to protrude from the back surface of the lower holder 12. Further, as shown in FIG. 4A, four positioning portions 124 are formed adjacent to the claw portions 114 of the upper holder 11. And the positioning part 124 is united with the nail | claw part 114 of the upper holder 11, and is arrange | positioned in the position which can be inserted in the positioning hole T5 of the attachment target 3 (refer FIG.7 (d) mentioned later). The holder 1 can be quickly and accurately attached to the attachment target 3 with the light emitting device 2 held by providing such a positioning portion 124.

  The energizing terminal 13 is for electrically connecting the external power source and the light emitting device 2. As shown in FIG. 4A, the energizing terminal 13 is provided inside the holder main body 10 around the second through hole H2. Specifically, as shown in FIG. It is provided so as to be sandwiched between the holders 12. Further, as shown in FIG. 4A, the energizing terminal 13 is provided inside the holder main body 10 with the wall 125 therebetween, and surrounds the through hole H2 inside the wall 125. Is provided.

  As shown in FIG. 1, the energizing terminal 13 is formed by bending a metal plate into a rectangular shape in accordance with the shape of the rectangular through hole H2. The energization terminal 13 includes a cathode-side energization terminal 13 a that contacts the cathode-side connection pad 23 of the light-emitting device 2 and an anode-side energization terminal 13 b that contacts the anode-side connection pad 23 of the light-emitting device 2. Composed.

  When the energizing terminal 13 is mounted inside the holder body 10 as shown in FIG. 4A, the respective ends 131a and 131b of the cathode side energizing terminal 13a and the anode side energizing terminal 13b are formed in the through holes H2. It is formed to be exposed. The tips 131 a and 131 b exposed in this way are configured to come into contact with the connection pads 23 of the light emitting device 2 when the light emitting device 2 is held by the holder 1. As a result, electric power is supplied to the light emitting element 22 by attaching a current supply wiring (not shown) to the outlet 14 of the holder body 10.

  Here, the tips 131a and 131b of the cathode-side energizing terminal 13a and the anode-side energizing terminal 13b are bent and bent as shown in FIG. 4A, and thus function as elastically energizing portions that are elastically deformed. . Accordingly, the ends 131a and 131b of the cathode-side energization terminal 13a and the anode-side energization terminal 13b have a spring property that presses the light-emitting device 2 and is in contact with the connection pad 23 of the light-emitting device 2 to energize. At the same time, the light emitting device 2 is biased in a direction away from the back surface side of the upper holder 11. As a result, the light emitting device 2 is in a state where the four corners are sandwiched by the tips 131a and 131b of the cathode side energizing terminal 13a and the anode side energizing terminal 13b and the claw portion 114.

  The energization terminal 13 is loaded with a driving voltage of the light emitting device 2. For example, when a high voltage load such as human body static electricity or lightning is applied to the lighting fixture in which the light emitting device 2 is arranged by the holder 1, the load is also applied to the energizing terminal 13. At this time, if the distance between the energizing terminal 13 and the mounting target 3 is short, a short circuit occurs between the energizing terminal 13 and the mounting target 3.

  FIG. 6 is an explanatory diagram for explaining the creeping distance from the mounting target, and (a) is an explanatory diagram for explaining the creeping distance from the mounting target in the lower holder that does not have a wall portion. ) Is an explanatory diagram for explaining the creeping distance from the mounting target in the lower holder having the wall portion, and will be described using the lower holder and the current-carrying terminal at the same position as in FIG. For example, as shown in FIG. 6A, when assuming the lower holder 12A in which the wall portion 125 is not formed, the distance (hereinafter referred to as creepage distance) D1 between the energizing terminal 13 and the mounting target 3 is short. Short circuit is likely to occur at that part. On the other hand, as shown in FIG. 6B, in the case of the lower holder 12 according to the present invention in which the wall portion 125 is formed, the creeping distance D2 can be provided longer by the amount of the wall portion 125, so that a short circuit occurs. Can be difficult. In FIGS. 6A and 6B, the upper holder 11 is not shown for convenience of explanation.

  The light emitting device 2 is a device that includes the light emitting element 22, and includes, for example, a COB structure light emitting diode package in which a plurality of light emitting elements 22 are mounted on the surface of the substrate 21. As shown in FIG. 1, the light-emitting device 2 includes a plate-shaped substrate 21, a plurality of light-emitting elements 22 mounted at the center of the surface of the substrate 21, and a foil-shaped electrically connected to the light-emitting elements 22. And a pair of connection pads 23. In addition, although the light-emitting device 2 is actually provided with the sealing resin which covers the some light emitting element 22, illustration is abbreviate | omitted here. Here, the light emitting element 22 indicates a single light emitting element or an assembly of a plurality of light emitting elements.

  The attachment object 3 is an object to which the light-emitting device 2 is attached and fixed. Examples of the attachment object 3 include a housing of an illumination lamp such as a light bulb, a street light, a downlight, and a spotlight, and a heat sink. Here, as an example of the attachment object 3, a heat sink is illustrated as shown in FIG. The mounting target 3 has a flat surface portion to which the light emitting device 2 can be mounted, and a fixing hole T4 and a positioning hole T5 are formed in the flat surface portion. The fixing hole T4 is a screw hole for fixing the holder 1 using the screw member F. The positioning hole T5 is a hole used for positioning of the holder 1 by inserting the claw portion 114 of the upper holder 11 and the positioning portion 124 of the lower holder 12. Note that the fixing hole T4 and the positioning hole T5 may be through holes.

  The holder 1 having the above-described configuration is provided with a wall portion 125 between the energization terminal 13 and the second through hole H2 in the holder main body 10, so that the height of the wall portion 125 can be attached. 3 and the energization terminal 13 increase, so that a short circuit hardly occurs between the attachment object 3 and the energization terminal 13. Therefore, according to the holder 1, it is possible to improve the insulation performance when the light emitting device 2 is fixed to the attachment object 3 without increasing the size of the holder.

  Here, when the light-emitting device 2 is actually fixed to the attachment object 3 by the holder 1 having the wall portion 125 as in the present invention (see FIG. 6B) and a large current is applied, the AC power supply is 1900V. And a short circuit occurred at 2000V. On the other hand, when a light source 2 is actually fixed to the attachment object 3 and a large current is passed by a holder that does not include the wall portion 125 (see FIG. 6A), it can withstand up to 1500 V with an AC power source. However, a short circuit occurred at 1600V. Therefore, as in the case of the holder 1 according to the present invention, the wall portion 125 is formed in the holder main body 10 to hide the exposure of the energization terminal 13, thereby making it difficult for a short circuit to occur.

[Attaching procedure of light emitting device with light emitting device holder]
Hereinafter, a procedure for attaching the light emitting device 2 using the holder 1 will be described with reference to FIG. 7 (refer to FIG. 1 as appropriate). FIG. 7 schematically shows the EE cross-sectional view of FIG. In addition, although illustration of the connection part of the upper holder 11 and the lower holder 12 is abbreviate | omitted, the holder 1 becomes the light emission surface side, and the bottom becomes a back surface side.

  First, as shown in FIGS. 7A to 7C, the light-emitting device 2 is fitted into the through-hole H2 of the lower holder 12 from the back side of the holder 1 as shown in FIGS. At that time, as shown in FIG. 7B, the claw portion 114 is pushed in the left-right direction by the light-emitting device 2 to be elastically deformed and spread in the left-right direction.
