Description

本発明は、発光素子と受電部を備えた配線基盤をハウジング内側に収めた光源装置と、この光源装置を装備した車両用灯具に関する。   The present invention relates to a light source device in which a wiring board having a light emitting element and a power receiving unit is housed inside a housing, and a vehicle lamp equipped with the light source device.

従来、ＬＥＤ等の発光素子やその制御回路をＦＰＣ（フレキシブルプリント基板）上に搭載し、そのＦＰＣをハウジングの内側に収容した光源装置が知られている。例えば、図６に示す従来の光源装置５１は、ＦＰＣ５２上にＬＥＤ５３と受電部５４を設け、絶縁材料製のハウジング５５に接続導体５６を埋設し、ハウジング５５の内側にＦＰＣ５２を挿入し、受電部５４を接続導体５６の給電部５７に接触させ、両者の接触部分を介して電力を外部電源からＬＥＤ５３に供給するように構成されていた。   Conventionally, a light source device in which a light emitting element such as an LED and its control circuit are mounted on an FPC (flexible printed circuit board) and the FPC is accommodated inside a housing is known. For example, a conventional light source device 51 shown in FIG. 6 includes an LED 53 and a power receiving unit 54 on an FPC 52, a connection conductor 56 is embedded in a housing 55 made of an insulating material, and the FPC 52 is inserted inside the housing 55. 54 is brought into contact with the power feeding portion 57 of the connection conductor 56, and power is supplied to the LED 53 from an external power source through the contact portion between the two.

なお、特許文献１には、図６に示すように構成された光源装置において、ＦＰＣと接続導体との接続部に板バネを設け、板バネの弾発力で発光素子側の受電部を外部電源側の給電子部に強く接触させるための技術が記載されている。   In Patent Document 1, in the light source device configured as shown in FIG. 6, a leaf spring is provided at the connection portion between the FPC and the connection conductor, and the power receiving portion on the light emitting element side is externally provided by the elastic force of the leaf spring.

次に、光源装置１の組立方法について説明する。まず、図２に示すように、上記のように構成された配線基盤３、ハウジング４およびアダプタ５を用意する。次に、図３に示すように、ＦＰＣ２の一対の補強板９をアダプタ５の第１保持部２６および第３保持部２８に挿入し、配線基盤３をアダプタ５に装着する。このとき、ハウジング４の外部で配線基盤３をアダプタ５に装着するため、ＦＰＣ２の受電部８と接続導体２２の給電側端部２４との接触状態を目視により容易に確認することができる。   Next, a method for assembling the light source device 1 will be described. First, as shown in FIG. 2, the wiring board 3, the housing 4, and the adapter 5 configured as described above are prepared. Next, as shown in FIG. 3, the pair of reinforcing plates 9 of the FPC 2 are inserted into the first holding part 26 and the third holding part 28 of the adapter 5, and the wiring board 3 is attached to the adapter 5. At this time, since the wiring board 3 is mounted on the adapter 5 outside the housing 4, the contact state between the power receiving unit 8 of the FPC 2 and the power feeding side end 24 of the connecting conductor 22 can be easily confirmed visually.

続いて、図４に示すように、配線基盤３が装着されたアダプタ５をハウジング４の内側に挿入し、アダプタ５の第２保持部２７をハウジング４の挿入孔２０に挿着する。このとき、アダプタ５の第１保持部２６において、係合壁２９がハウジング４の内壁面に当接し、係合壁２９と挟持壁３０との間にＦＰＣ２の一方の補強板９と接続導体２２の給電側端部２４が挟着され、受電部８が給電側端部２４に接触した状態に強く保持される。また、アダプタ５の第３保持部２８にＦＰＣ２の他方の補強板９が強固に保持されるとともに、アダプタ５の第２保持部２７によて接続導体２２の受電側端部２５がハウジング４の定位置に保持される。したがって、光源装置１を車両用灯具に装備した場合に、車両の振動に伴う受電部８と給電側端部２４との摺動摩耗を未然に防止することができる。   Subsequently, as shown in FIG. 4, the adapter 5 to which the wiring board 3 is attached is inserted into the housing 4, and the second holding portion 27 of the adapter 5 is inserted into the insertion hole 20 of the housing 4. At this time, in the first holding portion 26 of the adapter 5, the engagement wall 29 abuts on the inner wall surface of the housing 4, and the one reinforcing plate 9 and the connection conductor 22 of the FPC 2 are interposed between the engagement wall 29 and the holding wall 30. The power supply side end 24 is sandwiched and the power receiving unit 8 is strongly held in contact with the power supply side end 24. Further, the other reinforcing plate 9 of the FPC 2 is firmly held by the third holding portion 28 of the adapter 5, and the power receiving side end portion 25 of the connection conductor 22 is connected to the housing 4 by the second holding portion 27 of the adapter 5.

特に、この実施形態の光源装置１では、第１保持部２６および第２保持部２７を絶縁材料で一体成形し、その絶縁部材２３中に接続導体２２を埋設したので、単一のアダプタ５によって配線基盤３の組み付けおよび電気接続を簡単に行うことができる。また、絶縁部材２３が接続導体２２を絶縁しているため、ハウジング４を高熱伝導率のアルミニウムや導電性樹脂材料で成形することができ、特に小型の光源装置１において放熱性能を高めることが可能となる。さらに、第２保持部２７は密栓部として機能するので、特に、車両用灯具に装備される光源装置１において、アダプタ５の一部を利用してハウジング４の水密性能を高めることができる。   In particular, in the light source device 1 of this embodiment, the first holding unit 26 and the second holding unit 27 are integrally formed of an insulating material, and the connection conductor 22 is embedded in the insulating member 23. The wiring board 3 can be easily assembled and electrically connected. In addition, since the insulating member 23 insulates the connection conductor 22, the housing 4 can be formed of aluminum having a high thermal conductivity or a conductive resin material, and the heat dissipation performance can be enhanced particularly in the small light source device 1. It becomes. Furthermore, since the 2nd holding | maintenance part 27 functions as a sealing plug part, in the light source device 1 with which a vehicle lamp is equipped especially, the watertight performance of the housing 4 can be improved using a part of adapter 5.
