（実施形態１の作用の説明）
この実施形態１にかかる光源ユニット１、車両用灯具１００は、以上のごとき構成からなり、以下、その作用について説明する。 (Explanation of the operation of the first embodiment)
The light source unit 1 and the vehicle lamp 100 according to the first embodiment have the above-mentioned configurations, and the operation thereof will be described below.

まず、スイッチをオン操作する。すると、電流（駆動電流）は、電源側コネクタ５１、コネクタピン５０、接続部材５および回路を介して発光素子２０に供給される。すると、発光素子２０が発光して、発光素子２０から放射された光は、導光部材、インナーレンズを介して、もしくは、直接ランプレンズを通して、所定の配光パターン、たとえば、テールランプ用の配光パターンおよびストップランプ用の配光パターンで外部に照射される。ここで、発光素子２０の点灯は、回路の部品８により制御される。 First, turn on the switch. Then, the current (driving current) is supplied to the light emitting element 20 via the power supply side connector 51, the connector pin 50, the connecting member 5, and the circuit. Then, the light emitting element 20 emits light, and the light radiated from the light emitting element 20 has a predetermined light distribution pattern, for example, a light distribution for a tail lamp, through a light guide member, an inner lens, or directly through a lamp lens. The pattern and the light distribution pattern for the stop lamp illuminate the outside. Here, the lighting of the light emitting element 20 is controlled by the component 8 of the circuit.

発光素子２０の点灯時において、発光素子２０および回路の部品８で発生した熱は、基板３、追加基板４１、保持部材６、熱伝導性樹脂あるいは熱伝導性接着剤を介してソケット部材７に伝達され、かつ、ソケット部材７のフィン７０から外部に放射される。スイッチをオフ操作すると、電流が遮断され、発光素子２０が消灯する。これにより、車両用灯具１００は、消灯する。 When the light emitting element 20 is lit, the heat generated in the light emitting element 20 and the component 8 of the circuit is transferred to the socket member 7 via the substrate 3, the additional substrate 41, the holding member 6, the heat conductive resin or the heat conductive adhesive. It is transmitted and radiated to the outside from the fin 70 of the socket member 7. When the switch is turned off, the current is cut off and the light emitting element 20 is turned off. As a result, the vehicle lamp 100 is turned off.

ここで、発光素子２０の点灯制御が複雑化すると、回路の部品８および配線が多くなる。この発光素子２０の点灯制御の複雑化としては、たとえば、１灯断線時全灯消灯制御がある。この１灯断線時全灯消灯制御は、複数個この例では５個の発光素子２０のうちの少なくとも１個の発光素子２０が断線した場合において、点灯している残りの発光素子２０全てを消灯させる制御である。すなわち、複数個の発光素子２０のうちの少なくとも１個の発光素子２０が断線し、残りの発光素子２０が点灯したままの状態においては、所定の光量を満たさないので好ましい状態ではないので、点灯している残りの発光素子２０全てを消灯させる必要がある。この点灯制御を１灯断線時全灯消灯制御という。また、発光素子２０の実装数、たとえば、ＬＥＤの実装個数が増加すると、回路の部品８および配線が多くなる。 Here, if the lighting control of the light emitting element 20 becomes complicated, the number of circuit components 8 and wiring increases. As a complicated lighting control of the light emitting element 20, for example, there is a control of turning off all lights when one light is disconnected. In this example, when at least one of the five light emitting elements 20 is disconnected, all the remaining light emitting elements 20 that are lit are turned off. It is a control to make it. That is, in a state where at least one light emitting element 20 among the plurality of light emitting elements 20 is disconnected and the remaining light emitting elements 20 remain lit, the predetermined amount of light is not satisfied, which is not a preferable state. It is necessary to turn off all the remaining light emitting elements 20. This lighting control is called a control to turn off all lights when one light is disconnected. Further, as the number of light emitting elements 20 mounted, for example, the number of LEDs mounted increases, the number of circuit components 8 and wiring increases.

As a result, in the light source unit 1 and the vehicle lamp 100 according to the first embodiment, the lighting control of the light emitting element 20 becomes complicated, the number of circuit components 8 and wiring increases, and the number of mounted light emitting elements 20 increases. Therefore, when the number of circuit components 8 and wiring increases, it is possible to cope with the increase in circuit components 8 and wiring.

The heat generated in 8 can be transmitted to the socket member 7 via the holding member 6 and efficiently radiated from the socket member 7 to the outside.

この実施形態１にかかる光源ユニット１、車両用灯具１００は、基板３の回路と１枚の追加基板４１の回路との間を接続部材５で電気的に接続し、この接続部材５を保持部材６の連結部６０すなわちアルミプレートの左右両端部分の間に配置させる。また、この実施形態１にかかる光源ユニット１、車両用灯具１００は、１枚の追加基板４１の回路にコネクタピン５０を電気的に接続し、このコネクタピン５０を保持部材６の追加基板保持部６２すなわちアルミプレートの左右両先端部分の間に配置させる。この結果、この実施形態１にかかる光源ユニット１、車両用灯具１００は、接続部材５およびコネクタピン５０と保持部材６すなわちアルミプレートとの間において電気的ショートがない。これにより、この実施形態１にかかる光源ユニット１、車両用灯具１００は、基板３と１枚の追加基板４１とを上下二段に配置し、基板３と１枚の追加基板４１とに接続部材５を接続し、かつ、１枚の追加基板４１にコネクタピン５０を接続することができる。 In the light source unit 1 and the vehicle lamp 100 according to the first embodiment, the circuit of the substrate 3 and the circuit of one additional substrate 41 are electrically connected by a connecting member 5, and the connecting member 5 is held by the connecting member 5. 6 is arranged between the connecting portion 60, that is, the left and right end portions of the aluminum plate. Further, in the light source unit 1 and the vehicle lamp 100 according to the first embodiment, the connector pin 50 is electrically connected to the circuit of one additional board 41, and the connector pin 50 is connected to the additional board holding portion of the holding member 6. 62 That is, it is placed between the left and right tip portions of the aluminum plate. As a result, the light source unit 1 and the vehicle lamp 100 according to the first embodiment have no electrical short circuit between the connecting member 5 and the connector pin 50 and the holding member 6, that is, the aluminum plate. As a result, in the light source unit 1 and the vehicle lamp 100 according to the first embodiment, the substrate 3 and one additional substrate 41 are arranged in two upper and lower stages, and a connecting member is connected to the substrate 3 and one additional substrate 41. 5 can be connected and the connector pin 50 can be connected to one additional board 41.

この実施形態１にかかる光源ユニット１、車両用灯具１００は、ソケット部材７の外部に放熱用の複数のフィン７０をソケット部材７の軸Ｚに対して放射方向に設けたものである。この結果、この実施形態１にかかる光源ユニット１、車両用灯具１００は、フィン７０の枚数およびフィン７０の放熱面積を増加させることができ、その分、放熱効果が向上される。 The light source unit 1 and the vehicle lamp 100 according to the first embodiment are provided with a plurality of fins 70 for heat dissipation outside the socket member 7 in the radial direction with respect to the axis Z of the socket member 7. As a result, the light source unit 1 and the vehicle lamp 100 according to the first embodiment can increase the number of fins 70 and the heat dissipation area of the fins 70, and the heat dissipation effect is improved by that amount.

この実施形態１にかかる光源ユニット１、車両用灯具１００は、ソケット部材７に、基板３、１枚の追加基板４１および保持部材６からなるサブアセンブリを収納する空間部７１を設けたものである。この結果、この実施形態１にかかる光源ユニット１、車両用灯具１００は、基板３と１枚の追加基板４１とを保持部材６にソケット部材７の軸Ｚ方向に配置して保持しても、ソケット部材７の軸Ｚ方向の長さ（ソケット部材７の高さ）を、既存の物と同等にすることができる。すなわち、基板３と１枚の追加基板４１とのソケット部材７の軸Ｚ方向の長さをソケット部材７の空間部７１で吸収することができる。これにより、この実施形態１にかかる光源ユニット１、車両用灯具１００は、ソケット部材７の軸Ｚ方向の長さが長くなることにより、ソケット部材７をランプハウジング１０１に取り付けた時のソケット部材７の軸Ｚがランプハウジング１０１に対して傾き、光軸が傾くことが無い。 In the light source unit 1 and the vehicle lamp 100 according to the first embodiment, the socket member 7 is provided with a space portion 71 for accommodating a subassembly composed of a substrate 3, an additional substrate 41, and a holding member 6. ..

That is, the length of the socket member 7 between the substrate 3 and one additional substrate 41 in the axis Z direction can be absorbed by the space portion 71 of the socket member 7. As a result, in the light source unit 1 and the vehicle lamp 100 according to the first embodiment, the length of the socket member 7 in the axis Z direction becomes longer, so that the socket member 7 when the socket member 7 is attached to the lamp housing 101 The axis Z of the lamp housing 101 is tilted with respect to the lamp housing 101, and the optical axis is not tilted.
