Description

本発明は、ＬＥＤ等の半導体発光素子を備える半導体光源ユニット及びその半導体光源ユニットを用いた車両用照明装置に関する。   The present invention relates to a semiconductor light source unit including a semiconductor light emitting element such as an LED and a vehicle lighting device using the semiconductor light source unit.

図１１に示すように、一対のバスバー収容室５７１，５７１を有するハウジング５０３と、バスバー収容室５７１にそれぞれに収容されてハウジング５０３の素子装着開口５０８及びダイオード装着開口５０９から挿入したＬＥＤ（Ｌｉｇｈｔ Ｅｍｉｔｔｉｎｇ Ｄｉｏｄｅ）５０５及びツエナーダイオード５０７を保持して電気的に接続可能にした一対のバスバー５１１，５１１と、ＬＥＤ５０５からの出射光を屈折させるためのレンズ５０２を有してハウジング５０３に被着されるカバー５０１と、を備えたＬＥＤユニット（半導体光源ユニット）５１３が提案されている（例えば、特許文献１参照）。   As shown in FIG. 11, a housing 503 having a pair of bus bar housing chambers 571 and 571, and LEDs (Light Emitting) housed in the bus bar housing chamber 571 and inserted from the element mounting opening 508 and the diode mounting opening 509 of the housing 503, respectively. A cover having a pair of bus bars 511 and 511 that hold the diode 505 and the Zener diode 507 and can be electrically connected, and a lens 502 for refracting light emitted from the LED 505 and is attached to the housing 503 501 has been proposed (for example, see Patent Document 1).

一対のバスバー５１１，５１１は、それぞれ両端に第１圧接部５１６及び第２圧接部５１５が形成され、離間してハウジング５０３内に並列配置される。
第１圧接部５１６には、ＬＥＤ５０５及びツエナーダイオード５０７の各一対の接点部に弾接可能な少なくとも一対の主接触バネ片５３７が対向配置して形成されている。第２圧接部５１５には、被覆電線の被覆を切り裂き導体と電気的に接触するための圧接刃５１７が設けられている。

しかしながら、上記ＬＥＤユニット５１３は、第２圧接部５１５を被覆電線に圧接することで電気的に接続される電線接続構造を有するだけなので、例えばドームランプ等の車両用照明装置に用いられているウェッジバルブ（電球）に替えて取り付けることができない。即ち、ウェッジバルブが挿着される車両用照明装置のソケット部は、一対のバネ端子がウェッジバルブの板状端子部を挟持することにより電気的に接続する構造であり、上記ＬＥＤユニット５１３の第２圧接部５１５を一対のバネ端子に対して電気的に接触させることができないためである。   However, since the LED unit 513 has only a wire connection structure that is electrically connected by pressing the second pressure contact portion 515 to the covered wire, a wedge used in a vehicle lighting device such as a dome lamp, for example. It cannot be installed in place of a bulb (bulb). In other words, the socket portion of the vehicular lighting device into which the wedge bulb is inserted has a structure in which a pair of spring terminals are electrically connected by sandwiching the plate-like terminal portion of the wedge bulb. This is because the two pressure contact portions 515 cannot be brought into electrical contact with the pair of spring terminals.

本発明は上記状況に鑑みてなされたもので、その目的は、電線接続構造を有しつつ、ウェッジバルブと互換性を持たせることができる半導体光源ユニットと、光源取付け部にウェッジバルブまたは半導体光源ユニットを取り付けることができる車両用照明装置とを提供することにある。   The present invention has been made in view of the above circumstances, and an object thereof is to provide a semiconductor light source unit that can be compatible with a wedge bulb while having a wire connection structure, and a wedge bulb or a semiconductor light source in a light source mounting portion.

なお、本実施形態では第２端子部５５の電線接続構造が圧接刃６５となるが、第２端子部５５の電線接続構造は、この他、オスタブとして形成されていてもよい。第２端子部５５の電線接続構造がオスタブとして形成された場合には、電線に接続されたメス端子と嵌合することで、第２端子部５５は電気的に接続される。   In addition, although the electric wire connection structure of the 2nd terminal part 55 becomes the press-contacting blade 65 in this embodiment, the electric wire connection structure of the 2nd terminal part 55 may be formed as a male tab in addition to this. When the electric wire connection structure of the second terminal portion 55 is formed as a male tab, the second terminal portion 55 is electrically connected by fitting with a female terminal connected to the electric wire.

本実施形態のＬＥＤユニット１１では、ＬＥＤ１９及びツエナーダイオード２１が、陽極と陰極との間で並列に接続されている。このような電子部品の接続構造では、ＬＥＤ１９及びツエナーダイオード２１と、陽極との間に抵抗器２３を設けた回路としたい場合が想定される。本構成では第３端子部５７は、抵抗器２３の接続時、抵抗器２３の一対の接点部にそれぞれ接続する一対の副接触バネ片６１の間の連結部６６が分離される。連結部６６がカットされることで、それぞれの左バスバー１５及び右バスバー１７において、圧接刃６５に一方の副接触バネ片６１を介して一方の抵抗器接点部が接触した抵抗器２３は、他方の抵抗器接点部が他方の副接触バネ片６１に接触する。これにより、第２端子部５５と第３端子部５７との間に抵抗器２３が直列に設けられた回路が構成される。   In the LED unit 11 of this embodiment, the LED 19 and the Zener diode 21 are connected in parallel between the anode and the cathode. In such a connection structure of electronic components, it is assumed that a circuit in which a resistor 23 is provided between the LED 19 and the Zener diode 21 and the anode is desired. In this configuration, when the resistor 23 is connected, the third terminal portion 57 is separated from the connecting portion 66 between the pair of sub-contact spring pieces 61 connected to the pair of contact portions of the resistor 23. When the connecting portion 66 is cut, in each of the left bus bar 15 and the right bus bar 17, the resistor 23 in which one resistor contact portion is in contact with the pressure contact blade 65 via one sub-contact spring piece 61 is The resistor contact portion contacts the other sub-contact spring piece 61. Thereby, a circuit in which the resistor 23 is provided in series between the second terminal portion 55 and the third terminal portion 57 is configured.

ＬＥＤ１９は、接点部の設けられた面が、上段の主接触バネ片５９に向けられる。ツエナーダイオード２１は、接点部の設けられた面が、下段の主接触バネ片５９の側に向けられる。
本実施形態のＬＥＤユニット１１では、ＬＥＤ１９の接点間ピッチが、ツエナーダイオード２１の接点間ピッチよりも小さい。つまり、２つの電子部品は、異なる接点間ピッチとなっている。本実施形態の電子部品の接続構造では、このような異なる接点間ピッチの電子部品を同時に実装可能としている。すなわち、２本の左バスバー１５及び右バスバー１７の下段で近くに隣接する一対の主接触バネ片５９にＬＥＤ１９の一対の接点部が接触し、上段で離れて隣接する一対の主接触バネ片５９にツエナーダイオード２１の一対の接点部が接触する。 As for LED19, the surface in which the contact part was provided is orient | assigned to the main contact spring piece 59 of the upper stage. The surface of the Zener diode 21 on which the contact portion is provided is directed toward the lower main contact spring piece 59 side.
In the LED unit 11 of the present embodiment, the pitch between the contacts of the LEDs 19 is smaller than the pitch between the contacts of the Zener diode 21. That is, the two electronic components have different contact pitches. In the electronic component connection structure of the present embodiment, electronic components having such different pitches between contacts can be simultaneously mounted. That is, the pair of main contact spring pieces 59 adjacent to each other in the lower stage of the two left bus bars 15 and the right bus bar 17 are in contact with the pair of main contact spring pieces 59, and the pair of main contact spring pieces 59 adjacent to each other in the upper stage.
