　特許文献１においては、複数のＬＥＤソケットのそれぞれに電気コードを接続し、さらにこの電気コードに電気コネクタを接続してＬＥＤに対する給電を行っているため、複数個のＬＥＤソケットと複数本の電気コードが必要であり構成が複雑になるとともに、これらＬＥＤソケットと電気コードを接続する作業が面倒になる。さらに、複数本の電気コードを接続する電気コネクタも必要であり、ランプ全体の構造も複雑になる。特許文献２においては、複数個のＬＥＤを基板に対して直接接続しているので、ＬＥＤソケットや各ＬＥＤソケットに対して電気接続を行うための電気コードが不要になり、構成を簡略化する上では有利である。しかし、特許文献２でも基板に設けられた配線パターンに対して給電を行うためには配線パターンに電気コードを利用して電気コネクタを接続する必要があり、この電気接続のための構造が複雑になることは避けられない。 In Patent Document 1, an electric cord is connected to each of a plurality of LED sockets, and an electric connector is further connected to the electric cord to supply power to the LED.

Even when the electrical connector is incorporated in the electrical connector as in Document 1 or when the power feeding circuit assembly is incorporated in the lamp, an electrical connection structure for the power feeding circuit assembly is required, and this electrical connection structure complicates the overall structure of the lamp. Inevitable.

The incandescent reflector 3B is formed in a semi-cylindrical container shape having a reflecting surface 33 having a shape close to a paraboloid, and is fixedly supported on the projecting portion 22 of the base portion 2 using a boss 35 provided on the back surface. . In this incandescent reflector 3B, a window 34 provided on the reflecting surface 33 is disposed opposite to the bayonet mounting hole 22a provided in the overhanging portion 22, and the incandescent bulb 5 supported by the socket 7 with connector is placed in the window 34. Be placed.
　以上の構成によれば、ＬＥＤ４はベース部２の段部２１に予め一体的に取着されており、このベース部２はリフレクタ３Ａ（３）と共にランプハウジング１内に組み付けられる。また、ベース部２の基板コネクタ９には発光回路基板６が取り付けられ、さらに、ベース部２の張出部２２のバヨネット取付穴２２ａには白熱電球を支持したコネクタ付ソケット７が取り付けられ、さらにこのコネクタ付ソケット７のコネクタ部７２に電源側コネクタ８が嵌合されることによりリアランプが構成される。 According to the above configuration, the LED 4 is integrally attached to the step portion 21 of the base portion 2 in advance, and the base portion 2 is assembled in the lamp housing 1 together with the reflector 3A (3). Further, the light emitting circuit board 6 is attached to the board connector 9 of the base part 2, and the socket with connector 7 supporting the incandescent bulb is attached to the bayonet attachment hole 22a of the overhang part 22 of the base part 2, A rear lamp is formed by fitting the power supply side connector 8 to the connector portion 72 of the socket 7 with connector.
　図７は前記ベース部２に対する前記コネクタ付ソケット７と前記発光回路基板６の電気接続回路を説明するブロック配線図である。コネクタ付ソケット７のコネクタ部７２に嵌合される電源側コネクタ８は車体側の点灯制御装置につながる電気コード８１に接続されている。この電源側コネクタ８は、白熱電球５を点灯制御するための電力を給電する１本の白熱ラインＬ１と、複数のＬＥＤ４をテールランプ又はストップランプとして点灯制御するための電力を供給する２本のＬＥＤラインＬ２，Ｌ３と、白熱電球５とＬＥＤ４に共通の１本の接地ラインＬ４の合計４本のラインで構成されている。そして、白熱ラインＬ１はコネクタ付ソケット７のソケット部７１に設けられたコンタクト電極７１ａに接続されており、当該ソケット部７１に支持された白熱電球５に電気接続される。また、２本のＬＥＤラインＬ２，Ｌ３と接地ラインＬ４の合計３本のラインは前記コネクタ付ソケット７のフランジ７１ｂに設けられた３個の当接電極７１ｄにそれぞれ接続され、コネクタ付ソケット７をバヨネット取付穴２２ａに装着したときにこれら３つの当接電極７１ｄはバヨネット取付穴２２ａに臨んで配設された当接パッド２３ｂに電気接触され、さらにベース部２の通電路２３に電気接続される。 FIG. 7 is a block wiring diagram for explaining an electrical connection circuit between the socket 7 with connector and the light emitting circuit board 6 with respect to the base portion 2. The power supply side connector 8 fitted to the connector portion 72 of the socket with connector 7 is connected to an electric cord 81 connected to the lighting control device on the vehicle body side. The power supply side connector 8 includes one incandescent line L1 that supplies power for controlling the lighting of the incandescent bulb 5, and two LEDs that supply power for controlling the lighting of the plurality of LEDs 4 as a tail lamp or a stop lamp. It is composed of a total of four lines L1, L3, and one ground line L4 common to the incandescent bulb 5 and the LED 4. And the incandescent line L1 is connected to the contact electrode 71a provided in the socket part 71 of the socket 7 with a connector, and is electrically connected to the incandescent lamp 5 supported by the socket part 71. Further, a total of three lines of the two LED lines L2, L3 and the ground line L4 are respectively connected to the three contact electrodes 71d provided on the flange 71b of the socket 7 with connector, and the socket 7 with connector is connected. When mounted in the bayonet mounting hole 22a, these three contact electrodes 71d are in electrical contact with the contact pads 23b disposed facing the bayonet mounting hole 22a, and are further electrically connected to the energizing path 23 of the base portion 2. .
　前記基板コネクタ９のコンタクト片９１の一部は前記ＬＥＤラインＬ２，Ｌ３及び接地ラインＬ４に接続されている通電路２３に接続されている。そのため、発光回路基板６のコネクタ片６１が基板コネクタ９に挿入されたときには、当該コネクタ片６１を介して発光回路基板６の発光回路はこれらのラインＬ２，Ｌ３，Ｌ４に電気接続される。また、この基板コネクタ９のコンタクト片９１の他の一部は前記通電路２３を介して複数のＬＥＤ４にそれぞれ接続されている。これにより、電源側コネクタ８はコネクタ付ソケット７及び基板コネクタ９を介して発光回路基板６と各ＬＥＤ４に電気接続されることになり、電源側コネクタ８から供給される電力に基づいて発光回路基板６がＬＥＤ４の全ての発光を制御し、テールランプ又はストップランプとして点灯制御する。例えば、車体側の点灯制御装置からテールランプの点灯電力がＬＥＤラインＬ２を通して入力されると、この点灯電力は発光回路基板６に入力され、発光回路基板６では所定レベルの電力をＬＥＤ４に供給してＬＥＤ４を発光させ、テールランプを点灯状態とする。また、ラインＬ３を通してストップランプの点灯電力が入力されると、発光回路基板６では所定レベルの電力をＬＥＤ４に供給してＬＥＤ４を発光させ、ストップランプを点灯状態とする。 A part of the contact piece 91 of the board connector 9 is connected to the energization path 23 connected to the LED lines L2 and L3 and the ground line L4. Therefore, when the connector piece 61 of the light emitting circuit board 6 is inserted into the board connector 9, the light emitting circuit of the light emitting circuit board 6 is electrically connected to these lines L2, L3, L4 via the connector piece 61. Further, the other part of the contact piece 91 of the board connector 9 is connected to the plurality of LEDs 4 via the energization path 23. As a result, the power supply side connector 8 is electrically connected to the light emitting circuit board 6 and each LED 4 via the socket with connector 7 and the board connector 9, and the light emission circuit board is based on the power supplied from the power supply side connector 8. 6 controls all light emission of the LED 4 and controls lighting as a tail lamp or a stop lamp. For example, when the lighting power of the tail lamp is input from the lighting control device on the vehicle body side through the LED line L2, the lighting power is input to the light emitting circuit board 6, and the light emitting circuit board 6 supplies a predetermined level of power to the LED 4. The LED 4 is caused to emit light, and the tail lamp is turned on. When the stop lamp lighting power is input through the line L3, the light emitting circuit board 6 supplies a predetermined level of power to the LED 4 to cause the LED 4 to emit light, thereby turning on the stop lamp.
　また、前記コネクタ付ソケット７では、ソケット部７１のコンタクト電極７１ａはコネクタ部７２のコネクタ端子７２ａの一部に電気接続されている。そのため、車体側の点灯制御装置から電源側コネクタ８を通して入力されるバックアップランプの点灯電力はコネクタ端子７２ａから直接コンタクト電極７１ａに供給され、さらに白熱電球５に供給されて白熱電球５が点灯され、バックアップランプを点灯状態とする。 In the socket with connector 7, the contact electrode 71 a of the socket part 71 is electrically connected to a part of the connector terminal 72 a of the connector part 72. Therefore, the lighting power of the backup lamp inputted from the lighting control device on the vehicle body side through the power supply side connector 8 is directly supplied from the connector terminal 72a to the contact electrode 71a, and further supplied to the incandescent bulb 5, and the incandescent bulb 5 is lit. Turn on the backup lamp.
　したがって、このリアランプでは、電源側コネクタ８に接続されている電気コード８１を除けば、複数のＬＥＤと１つの白熱電球を点灯制御するための電気コードは全く不要である。すなわち、コネクタ付ソケット７のコネクタ部７２に嵌合された電源側コネクタ８を通して供給される電力は、コネクタ付ソケット７のソケット部７１において白熱電球５に直接に給電される。また、同電力はコネクタ付ソケット７の３つの当接電極７１ｄからこれに電気接触しているベース部２の通電路２３に直接的に給電される。そして、基板コネクタ９におけるコンタクト片９１とコネクタ片６１との電気接触により通電路２３から発光回路基板６に給電される。発光回路基板６は通電路２３を通して入力される電力に基づいてＬＥＤ４の発光を制御すべく所要の電力を基板コネクタ９を介して通電路２３に供給し、この制御された電力は当該通電路２３を介して複数の段部２１にまで供給され、各段部２１に実装されているＬＥＤ４が発光される。 Therefore, in this rear lamp, except for the electric cord 81 connected to the power supply side connector 8, an electric cord for controlling the lighting of a plurality of LEDs and one incandescent bulb is completely unnecessary. That is, the electric power supplied through the power supply side connector 8 fitted to the connector part 72 of the connector-attached socket 7 is directly supplied to the incandescent lamp 5 in the socket part 71 of the connector-attached socket 7. Further, the same electric power is directly supplied from the three contact electrodes 71d of the socket 7 with connector to the energizing path 23 of the base portion 2 that is in electrical contact therewith. Then, power is supplied to the light emitting circuit board 6 from the energizing path 23 by electrical contact between the contact piece 91 and the connector piece 61 in the board connector 9. The light emitting circuit board 6 supplies necessary power to the current path 23 via the board connector 9 to control light emission of the LED 4 based on the power input through the current path 23, and the controlled power is supplied to the current path 23. To the plurality of step portions 21, and the LEDs 4 mounted on each step portion 21 emit light.
　このように、発光回路基板６を備えるベース部２はプリント回路基板として構成されており、ＬＥＤ４を点灯制御するための電気コードは全く不要になる。すなわち、白熱電球５を支持して点灯させるためのコネクタ付ソケット７によりベース部２の通電路２３を介してＬＥＤ４への給電が可能になるので、ＬＥＤ４を発光させるための独立した電気コネクタが不要になる。そのため、ベース部２の構成が簡略なものとなり製造が極めて容易になるとともに、リアランプの電気系統の構成部品数が削減され、構造の簡略化やランプの小型化、軽量化が実現できる。また、電気コードの劣化や損傷が生じることもなく、信頼性の高いランプが構成できる。さらに、リアランプを自動車の車体に組み立てる際の組立作業も簡略化される。すなわち、車体に取り付けられたリアランプのランプボディ１１の蓋部１４を開き、開口１３を通して発光回路基板６を基板コネクタ９に装着する。また、開口１３を通して張出部２２のバヨネット取付穴２２ａにコネクタ付ソケット７を嵌着し、その上で当該コネクタ付ソケット７のコネクタ部７２に電源側コネクタ８を嵌合することにより組み立てを完了することができる。 Thus, the base portion 2 including the light emitting circuit board 6 is configured as a printed circuit board, and an electric cord for controlling the lighting of the LED 4 is completely unnecessary. In other words, the socket 4 with a connector for supporting and lighting the incandescent bulb 5 can supply power to the LED 4 through the energization path 23 of the base portion 2, so that an independent electrical connector for causing the LED 4 to emit light is unnecessary. become. Therefore, the structure of the base part 2 is simplified and the manufacture becomes extremely easy, the number of components of the electric system of the rear lamp is reduced, and the structure can be simplified and the lamp can be reduced in size and weight. In addition, a highly reliable lamp can be configured without causing deterioration or damage of the electric cord. Furthermore, the assembling work when assembling the rear lamp to the car body is simplified. That is, the lid 14 of the lamp body 11 of the rear lamp attached to the vehicle body is opened, and the light emitting circuit board 6 is attached to the board connector 9 through the opening 13. Further, the socket 7 with connector is fitted into the bayonet mounting hole 22a of the overhanging portion 22 through the opening 13, and then the power supply side connector 8 is fitted into the connector portion 72 of the socket 7 with connector. can do.
　この実施形態１では基板コネクタ９は、コンタクト片９１を含めてベース部２を構成する樹脂基材と通電路２３を構成する導電材とで構成されているので、電気接続を行うための電極等を形成するための金属部材は不要であり、この面でも部品点数が削減できる。さらに、実施形態１のコネクタ付ソケット７は従来の車両用灯具において提供されているコネクタ付ソケットをそのまま、あるいは一部の構成を変更するだけで得ることができるので、既存部品を利用した廉価なランプを構成することが可能である。 In the first embodiment, the board connector 9 is composed of a resin base material that constitutes the base portion 2 including the contact piece 91 and a conductive material that constitutes the current-carrying path 23. The metal member for forming is unnecessary, and the number of parts can be reduced also in this aspect. Furthermore, since the socket with connector 7 of Embodiment 1 can be obtained as it is or with only a part of the configuration of the socket with connector provided in the conventional vehicle lamp, it is inexpensive using existing parts. It is possible to construct a lamp.
　また、この実施形態１ではランプハウジング１の外部から発光回路基板６をベース部２に対して着脱可能であるので、発光回路基板６の交換が容易であり、メンテナンスの面で有利であるとともに、電気的な規格の異なる発光回路基板への交換も可能であり、発光規格の異なるランプを構成することも可能である。 In the first embodiment, since the light emitting circuit board 6 can be attached to and detached from the base portion 2 from the outside of the lamp housing 1, the light emitting circuit board 6 can be easily replaced, which is advantageous in terms of maintenance. It is possible to replace the light-emitting circuit board with a different electrical standard, and it is also possible to configure a lamp with a different light-emission standard.
（実施形態２）
　実施形態１では、ベース部２の段部２１にそれぞれＬＥＤ４を半田付け等によって搭載しているが、半田付けに際しての所謂リフロー法の適用が難しい場合にはＬＥＤをユニット化してもよい。図８（ａ），（ｂ）はその一例の実施形態２の外観斜視図と断面図を示しており、ここでは段部２１の一部のみを示している。ベース部２の各段部２１には隣接する段部の境界となる壁の一部にそれぞれ光源コネクタ９Ａが形成されている。また、各段部２１に搭載されるＬＥＤ４はベース部２とは独立した小型の光源基板４Ａに搭載されており、この光源基板４Ａの一辺に設けられたコネクタ片４１が前記光源コネクタ９Ａに着脱可能とされ、装着されたときに光源基板４Ａがベース部２の裏面の通電路２３に電気接続されるように構成されている。 (Embodiment 2)
In the first embodiment, the LEDs 4 are mounted on the step portions 21 of the base portion 2 by soldering or the like, but the LEDs may be unitized when it is difficult to apply a so-called reflow method at the time of soldering. FIGS. 8A and 8B are an external perspective view and a cross-sectional view of the second embodiment, and only a part of the stepped portion 21 is shown here. In each step portion 21 of the base portion 2, a light source connector 9 </ b> A is formed on a part of a wall that becomes a boundary between adjacent step portions. The LEDs 4 mounted on the respective step portions 21 are mounted on a small light source substrate 4A independent of the base portion 2, and a connector piece 41 provided on one side of the light source substrate 4A is attached to and detached from the light source connector 9A. The light source substrate 4 </ b> A is configured to be electrically connected to the energization path 23 on the back surface of the base portion 2 when it is mounted.
　前記光源基板４Ａの裏面には所要パターンの導電膜からなる導電回路４２が形成されており、この導電回路４２は光源基板４Ａの表面に設けられた搭載電極４３にスルーホール４４で電気接続されている。また、前記導電回路４２の一部は前記コネクタ片４１の裏面にまで延長されている。ＬＥＤ４は電極４ａが光源基板４Ａの表面の搭載電極４３に半田付け等により搭載されており、ユニット化されている。また、各段部２１に形成されている光源コネクタ９Ａは実施形態１の基板コネクタ９と同様な構成であり、表面にコンタクト電極９１ａとしての導電膜を有する少なくとも２つのコンタクト片９１を有し、各光源基板４Ａのコネクタ片４１が挿入されたときに、当該コネクタ片４１の裏面の導電回路４２に対してコンタクト電極９１ａが電気接続される。 A conductive circuit 42 made of a conductive film having a required pattern is formed on the back surface of the light source substrate 4A. The conductive circuit 42 is electrically connected through a through hole 44 to a mounting electrode 43 provided on the surface of the light source substrate 4A. Yes. A part of the conductive circuit 42 is extended to the back surface of the connector piece 41. In the LED 4, the electrode 4a is mounted on the mounting electrode 43 on the surface of the light source substrate 4A by soldering or the like, and is unitized. Further, the light source connector 9A formed in each step portion 21 has the same configuration as the substrate connector 9 of the first embodiment, and has at least two contact pieces 91 having a conductive film as the contact electrode 91a on the surface, When the connector piece 41 of each light source substrate 4A is inserted, the contact electrode 91a is electrically connected to the conductive circuit 42 on the back surface of the connector piece 41.
　この実施形態２では、ベース部２に対するＬＥＤ４の配設に際しては、それぞれＬＥＤ４を搭載した光源基板４Ａをベース部２の各段部２１の光源コネクタ９Ａに装着するだけでよく、ベース部２に対する半田付けは不要である。光源基板４Ａに対するＬＥＤ４の搭載に際してはリフロー法が適用できるので、実施形態１のようなベース部２に対してリフロー法でＬＥＤ４を搭載することが難しい場合に有効であり、ランプの組立作業の簡略化、迅速化が実現できる。また、この実施形態２では光源基板４Ａを交換することが可能であるので、光源基板４Ａに搭載したＬＥＤ４の交換等のメンテナンスが容易であるとともに、異なる種類のＬＥＤへの交換も可能である。さらに、光源基板４Ａを設けることによりＬＥＤ４で発生した熱が直接ベース部２に伝達することが抑制されるので、ベース部２に要求される耐熱性を緩和することができ、廉価な樹脂材を採用することも可能になる。また、この実施形態２のランプでは白熱電球を備えていないが、コネクタ付ソケット７が白熱電球を支持しないようにすれば、実施形態１の白熱電球を点灯させるためのコネクタ付ソケット７をそのまま利用することができるので、バックアップランプ以外のランプをリアランプに複合させようとする場合でも同じソケット付コネクタを採用することが可能であり、部品点数のさらなる低減が可能である。 In the second embodiment, when the LEDs 4 are disposed on the base portion 2, it is only necessary to attach the light source substrate 4 </ b> A on which the LEDs 4 are mounted to the light source connectors 9 </ b> A of the respective step portions 21 of the base portion 2. No attachment is necessary. Since the reflow method can be applied when the LED 4 is mounted on the light source substrate 4A, it is effective when it is difficult to mount the LED 4 on the base portion 2 as in the first embodiment by the reflow method, and the lamp assembly operation is simplified. Can be realized. In the second embodiment, since the light source substrate 4A can be replaced, maintenance such as replacement of the LEDs 4 mounted on the light source substrate 4A is easy, and replacement with different types of LEDs is also possible. Furthermore, since the heat generated in the LED 4 is prevented from being directly transferred to the base portion 2 by providing the light source substrate 4A, the heat resistance required for the base portion 2 can be reduced, and an inexpensive resin material can be used. It can also be adopted. In addition, the lamp of the second embodiment does not include an incandescent bulb. However, if the socket with connector 7 does not support the incandescent bulb, the socket with connector 7 for lighting the incandescent bulb of the first embodiment is used as it is. Therefore, even when a lamp other than the backup lamp is combined with the rear lamp, the same connector with a socket can be employed, and the number of parts can be further reduced.
　本発明は少なくとも一部にＬＥＤあるいはＬＥＤ以外の複数の半導体発光素子を光源とするランプに適用することが好ましい。また、実施形態ではベース部にリフレクタを固定した構造を説明したが、リフレクタ以外の光学部材、例えばインナーレンズや疑似リフレクタ等の光学部材をベース部に対して固定することができるように構成してもよい。本発明におけるベース部、基板コネクタ、さらにはコネクタ付ソケットの構成は実施形態１，２の構成に限られるものでない。 The present invention is preferably applied at least in part to a lamp that uses LEDs or a plurality of semiconductor light emitting elements other than LEDs as light sources.
