本発明は、自動車のヘッドランプを始めとして、リヤコンビネーションランプやフォグランプ等に用いられる車両用灯具に関する。   The present invention relates to a vehicular lamp used for a rear combination lamp, a fog lamp, and the like including an automobile headlamp.

従来、車両用灯具として例えば特許文献1に示されているように、光源として発光ダイオード(LED)等の半導体型光源を用い、これをリフレクタと共にヒートシンク部材(固定部材)に組付けて、半導体型光源の発熱を該ヒートシンク部材により拡散して放熱するようにしたものが知られている。
特開2006−302714号公報
Conventionally, as shown in, for example, Patent Document 1 as a vehicle lamp, a semiconductor light source such as a light emitting diode (LED) is used as a light source, and this is assembled to a heat sink member (fixing member) together with a reflector. A heat source is known in which heat generated by a light source is diffused by the heat sink member.
JP 2006-302714 A

前記従来の車両用灯具にあっては、半導体型光源は給電アタッチメント部材に位置決めして固定配置され、この給電アタッチメント部材をヒートシンク部材に嵌挿固定することにより、該半導体型光源がヒートシンク部材の所定部位に配置されるようにしている。   In the conventional vehicular lamp, the semiconductor-type light source is positioned and fixedly disposed on the power supply attachment member, and the semiconductor-type light source is fixed to the heat sink member by inserting and fixing the power supply attachment member to the heat sink member. It is arranged at the site.

このため、半導体型光源と給電アタッチメント部材との組付誤差、および給電アタッチメント部材とヒートシンク部材との組付誤差が集積されて、半導体型光源とリフレクタ,シェード,投影レンズ等との光学的位置関係に狂いが生じて、配光性能に悪影響及ぼしてしまうことは否めない。 Therefore, the assembly error between the semiconductor light source and the power supply attachment member and the assembly error between the power supply attachment member and the heat sink member are integrated, and the optical positional relationship between the semiconductor light source and the reflector, shade, projection lens, etc. It occurs is deviation, the undeniable that adversely affects the light distribution performance.

一方、前記半導体型光源の背面とヒートシンク部材の光源取付面とに、相互に係合するロケートピンとロケート孔とを設けて、これらロケートピンとロケート孔との係合により半導体型光源を位置決めして、直接、前記光源取付面に固定することも行われてはいるが、前記ロケートピンとロケート孔の加工精度管理が困難で、この場合も半導体型光源と他の光学系部材との位置関係に微妙な狂いを生じてしまう。   On the other hand, the rear surface of the semiconductor type light source and the light source mounting surface of the heat sink member are provided with a locating pin and a locating hole that are engaged with each other, and the semiconductor type light source is positioned by the engagement between the locating pin and the locating hole, Although it is also directly fixed to the light source mounting surface, it is difficult to manage the processing accuracy of the locating pin and the locating hole, and in this case also, the positional relationship between the semiconductor light source and other optical system members is delicate. It will cause madness.

そこで、本発明は半導体型光源をヒートシンク部材の光源取付面上に精度良く組付けることができて、配光性能を向上することができる車両用灯具を提供するものである。   Therefore, the present invention provides a vehicular lamp that can accurately assemble a semiconductor-type light source on a light source mounting surface of a heat sink member, and can improve light distribution performance.

本発明の車両用灯具、半導体型光源と、該半導体型光源の出射光の一部を所定の方向に向けて反射するリフレクタと、これら半導体型光源およびリフレクタ等の光学系部材を集約的に配置したヒートシンク部材と、を備え、前記ヒートシンク部材の半導体型光源が固定配置される平坦な光源取付面には、該光源取付面上に突設されて少くとも前記半導体型光源の一側端面と係止するストッパーと、該ストッパーと対峙して配設されて前記半導体型光源の他側端面を前記ストッパー側に向けて押圧するばね部材が設けられ、前記半導体型光源が、これらストッパーとばね部材との対向的な挟圧により位置決めされた構造であって、前記半導体型光源の前記光源取付面上への固定が、該光源取付面上に位置決め固定されて半導体型光源と電気的に接続される給電部材により行われ、該給電部材は、前記半導体型光源の周縁部を上方から押え付ける平板状のホルダー部と、該ホルダー部の一側端に一体的に外方に向けて突設された四角柱状のコネクタ部とを備え、該コネクタ部が前記光源取付面に形成された角形溝部に嵌合固定されて、該コネクタ部の端部がヒートシンク部材の側方に突出して配置されていることを主要な特徴としている。 Vehicular lamp of the present invention includes a semiconductor-type light source, a reflector for reflecting a part in a predetermined direction of the outgoing light of the semiconductor-type light source, collectively the optical member such as these semiconductor-type light source and a reflector A flat light source mounting surface on which the semiconductor light source of the heat sink member is fixedly disposed, and is projected on the light source mounting surface and at least one side end surface of the semiconductor light source. A stopper for locking, and a spring member arranged to face the stopper and pressing the other end surface of the semiconductor-type light source toward the stopper side are provided, and the semiconductor-type light source includes the stopper and the spring member. a structure that is positioned by opposed specific clamping of the fixing of the semiconductor-type light source of the light source mounting surface on the semiconductor-type light source electrically is positioned and fixed on the light source mounting surface The power supply member is connected to a flat plate-shaped holder portion that presses the peripheral edge of the semiconductor-type light source from above, and projects outwardly integrally with one end of the holder portion. A rectangular column-shaped connector portion provided, and the connector portion is fitted and fixed in a square groove portion formed on the light source mounting surface, and an end portion of the connector portion is disposed so as to protrude to the side of the heat sink member. Is the main feature.

前記半導体型光源は、その背面をヒートシンク部材の光源取付面に重合して、該半導体型光源の一側端面を該光源取付面上に突設されたストッパーに面接触して当接係止することにより、該半導体型光源の配設基準位置が定められる。そして、該半導体型光源の他側端面を前記ばね部材により前記ストッパー側に向けて押圧することによって、該半導体型光源の配設位置が確定される。   The semiconductor-type light source has its rear surface overlapped with the light source mounting surface of the heat sink member, and one side end surface of the semiconductor-type light source is brought into surface contact with and locked to a stopper projecting on the light source mounting surface. Thus, the arrangement reference position of the semiconductor light source is determined. And the arrangement | positioning position of this semiconductor type light source is decided by pressing the other side end surface of this semiconductor type light source toward the said stopper side with the said spring member.

本発明によれば、ヒートシンク部材の光源取付面上に突設したストッパーに半導体型光源の一側端面を突当てて面接触させることにより、該光源取付面上における半導体型光源の配設基準位置が定められ、このストッパーとばね部材との対向的な挟圧によって該半導体型光源の配設位置が確定されるので、前記従来の給電アタッチメント部材の如き中間媒体がなく、半導体型光源の組付精度を高めることができる。   According to the present invention, the arrangement reference position of the semiconductor light source on the light source mounting surface is brought into contact with the stopper projecting on the light source mounting surface of the heat sink member by abutting one end face of the semiconductor light source on the surface. Since the arrangement position of the semiconductor light source is determined by the opposing clamping pressure between the stopper and the spring member, there is no intermediate medium as in the conventional power supply attachment member, and the semiconductor light source is assembled. Accuracy can be increased.

しかも、前記ストッパーと半導体型光源の相互の接触面の精度を出せばよいので、加工精度管理が容易で半導体型光源の位置決めを正確に行えて、他のリフレクタ等との光学的位置関係に狂いを生じることがなく、これにより配光性能を向上することができる。   In addition, the accuracy of the contact surface between the stopper and the semiconductor-type light source only needs to be obtained, so that the processing accuracy can be easily managed and the positioning of the semiconductor-type light source can be performed accurately, and the optical positional relationship with other reflectors, etc. is not correct. Thus, the light distribution performance can be improved.

A heat sink member 20 arranged in a concentrated manner.

この灯具ユニット1が図外のランプハウジングと素通しのアウターレンズとで形成される灯室内に配設されて、ヘッドランプが構成される。   This lamp unit 1 is disposed in a lamp chamber formed by a lamp housing (not shown) and a transparent outer lens to constitute a headlamp.

前記リフレクタ11の反射面11aは、楕円または楕円を基本とする反射面、例えば、回転楕円面または楕円を基本とした自由曲面からなる。図2の鉛直断面において、リフレクタ11の反射面11aは、例えば楕円をその長軸に沿って半分にした半楕円の形状を有し、反射面11aの前端部側は半円柱状のフード部11Aとされている。   The reflecting surface 11a of the reflector 11 is an ellipse or a reflecting surface based on an ellipse, for example, a free-form surface based on a spheroid or ellipse. In the vertical cross section of FIG. 2, the reflecting surface 11a of the reflector 11 has, for example, a semi-elliptical shape in which an ellipse is halved along its long axis, and the front end side of the reflecting surface 11a is a semi-columnar hood portion 11A. It is said that.

このリフレクタ11は、例えば光不透過性の合成樹脂材で形成され、リフレクタ11の内面にアルミ蒸着や銀塗装を施して前記反射面11aが形成される。   The reflector 11 is formed of, for example, a light-impermeable synthetic resin material, and the reflective surface 11a is formed by performing aluminum vapor deposition or silver coating on the inner surface of the reflector 11.

前記リフレクタ11の反射面11aは第1焦点F1と第2焦点F2とを備え、この第1焦点F1またはその近傍に前記半導体型光源10の発光部10aが配設される。これにより、半導体型光源10から射出される光のうち、リフレクタ11の反射面11aにより反射された光は、該リフレクタ11の第2焦点F2またはその近傍に集光される。   The reflecting surface 11a of the reflector 11 includes a first focal point F1 and a second focal point F2, and the light emitting unit 10a of the semiconductor-type light source 10 is disposed at or near the first focal point F1. Thereby, of the light emitted from the semiconductor-type light source 10, the light reflected by the reflecting surface 11 a of the reflector 11 is collected at the second focal point F <b> 2 of the reflector 11 or in the vicinity thereof.

前記半導体型光源10は、例えば発光ダイオード(LED)や有機ELおよび無機ELを含むエレクトロルミネッセンス(EL)など、半導体に電圧を印加することによって得られるルミネッセンス(発光現像)を利用した光源である。   The semiconductor light source 10 is a light source using luminescence (light emission development) obtained by applying a voltage to a semiconductor, such as a light emitting diode (LED) or an electroluminescence (EL) including an organic EL and an inorganic EL.

この半導体型光源10は、平面方形の基板10Aを有し、該基板10Aの左右両側上面に端子10bが設けられ、また、前記発光部10aを覆って透明なドーム状カバー10cが付設されている。   This semiconductor-type light source 10 has a flat rectangular substrate 10A, terminals 10b are provided on the upper surfaces of the left and right sides of the substrate 10A, and a transparent dome-shaped cover 10c is attached to cover the light emitting portion 10a. .

前記投影レンズ12は、少なくとも何れか一方の側面が球面または略球面の形状を有する凸レンズである。本実施形態では、投影レンズ12の両側面が凸型の略球面形状を有し、灯具前方側の側面(前面)は灯具後方側の側面(後面)に比べて曲率半径が小さい。投影レンズ12の形状はこれに限らず、レンズ光軸方向の厚みが中心から外周にかけて薄くなる凸レンズであればよく、例えば、灯具後方側の側面(後面)が略平坦な面とされた平凸レンズであってもよい。   The projection lens 12 is a convex lens having a spherical or substantially spherical shape on at least one side surface. In this embodiment, both side surfaces of the projection lens 12 have a convex substantially spherical shape, and the side surface (front surface) on the front side of the lamp has a smaller radius of curvature than the side surface (rear surface) on the rear side of the lamp. The shape of the projection lens 12 is not limited to this, and may be any convex lens whose thickness in the lens optical axis direction becomes thinner from the center to the outer periphery. For example, a plano-convex lens whose side surface (rear surface) on the rear side of the lamp is a substantially flat surface. It may be.

前記台座32は、前記基板10Aの投影平面形状に整合する方形に形成され、その底面中央部には少なくとも前端面が台座32の前端面と面一な四角柱状の脚部32aを一体に備えている。   The pedestal 32 is formed in a square shape that matches the projected plane shape of the substrate 10A, and at the center of the bottom surface thereof is integrally provided with a square columnar leg portion 32a whose front end surface is flush with the front end surface of the pedestal 32. Yes.

一方、前記光源取付面21には前記板ばね31のU字状底部が底付きする所定深さの平面方形の嵌合孔28が形成されている。この嵌合孔28は前記板ばね31と共に台座32の脚部32aを嵌合配置するもので、脚部32aの前後寸法よりも大きく設定され、脚部32aの前側に残余部28aが形成されるようにしている。   On the other hand, the light source mounting surface 21 is formed with a flat rectangular fitting hole 28 having a predetermined depth at which the U-shaped bottom portion of the leaf spring 31 bottoms. The fitting hole 28 fits and arranges the leg portion 32a of the pedestal 32 together with the leaf spring 31, and is set to be larger than the front and rear dimensions of the leg portion 32a, and a remaining portion 28a is formed on the front side of the leg portion 32a. I am doing so.

前記後部ストッパー30Rおよび側部ストッパー30Sは、前記嵌合孔28の後縁および左右側縁に沿って立設されている。   The rear stopper 30R and the side stopper 30S are erected along the rear edge and the left and right side edges of the fitting hole 28.

そして、前記台座32はその脚部32aを前記嵌合孔28に上方より嵌入し、台座32の後端面および側端面を前記後部ストッパー30Rおよび側部ストッパー30Sに面接触させて係止し、該嵌合孔28にサブアッセンブリされる。   The pedestal 32 has its leg 32a fitted into the fitting hole 28 from above, and the rear end surface and the side end surface of the pedestal 32 are brought into surface contact with the rear stopper 30R and the side stopper 30S and locked. Sub-assembled in the fitting hole 28.

半導体型光源10は、このように嵌合孔28にサブアッセンブリされた台座32上に基板10Aを載置し、該基板10Aの後端面と左右側端面とを前記後部ストッパー30Rと側部ストッパー30Sとに面接触させて係止した状態で、前記嵌合孔28の前側の残余部28aに板ばね31を差し込むことにより、基板10Aが台座32と共に後部ストッパー30Rと板ばね31とにより前後方向に挟圧されて前後方向の位置決めが行われ、かつ、左右の側部ストッパー30Sにより左右方向の位置決めが行われる。   The semiconductor-type light source 10 places the substrate 10A on the pedestal 32 thus sub-assembled in the fitting hole 28, and the rear end surface and the left and right end surfaces of the substrate 10A are connected to the rear stopper 30R and the side stopper 30S. With the plate spring 31 inserted into the remaining portion 28a on the front side of the fitting hole 28 in a state of being brought into surface contact with the base plate, the base plate 10A is moved in the front-rear direction by the rear stopper 30R and the plate spring 31 together with the base 32. Positioning in the front-rear direction is performed by being pinched, and positioning in the left-right direction is performed by the left and right side stoppers 30S.

このとき、前記U字状の板ばね31の前側のばね片31aの上端縁が前記取付面21とほぼ面一に整合する長さに、および後側のばね片31bの上端縁が前記基板10Aの上面と面一もしくは若干上方に突出する長さに設定されている。また、この板ばね31の後側のばね片31bの上端末は若干前側に向けて傾斜したガイド片31cとして曲折成形され、先に該板ばね31を前記嵌合孔28の残余部28aに差し込んで自体の弾性作用により係着させておき、後から半導体型光源10の基板10Aを前記ストッパー30とガイド片31cとの間に上方から差し込んで係着が可能となるようにされている。   At this time, the upper end edge of the front spring piece 31a of the U-shaped leaf spring 31 is aligned with the mounting surface 21, and the upper end edge of the rear spring piece 31b is the substrate 10A. The length is set so as to be flush with or slightly above the upper surface. The upper end of the spring piece 31b on the rear side of the leaf spring 31 is bent and formed as a guide piece 31c slightly inclined toward the front side, and the leaf spring 31 is inserted into the remaining portion 28a of the fitting hole 28 first. The substrate 10A of the semiconductor light source 10 is inserted between the stopper 30 and the guide piece 31c from above and can be engaged later.

このように、ヒートシンク部材20の光源取付面21上に、ストッパー30と板ばね31とによって正確に位置決めして配設された半導体型光源10は、該半導体型光源10と電気的に接続される給電部材40と、固定フレーム50とによってヒートシンク部材20にしっかりと固定される。   As described above, the semiconductor-type light source 10 that is accurately positioned on the light-source mounting surface 21 of the heat sink member 20 by the stopper 30 and the leaf spring 31 is electrically connected to the semiconductor-type light source 10. The power supply member 40 and the fixed frame 50 are firmly fixed to the heat sink member 20.

給電部材40は適宜の合成樹脂材からなり、前記半導体型光源10の周縁部、具体的には前記基板10Aの周縁部を上方から押え付けるホルダー部41と、該ホルダー部41の一側端に一体的に外方に向けて突設されて、図外の電源側コネクタが接続されるコネクタ部42と、を備えている。   The power supply member 40 is made of an appropriate synthetic resin material, and includes a holder 41 that presses the peripheral edge of the semiconductor light source 10, specifically, the peripheral edge of the substrate 10 </ b> A from above, and one side end of the holder 41. And a connector portion 42 that projects integrally outward and to which a power supply side connector (not shown) is connected.

前記ホルダー部41は平面方形に形成され、その周縁部に一段低く一体に有段成形されて前記ヒートシンク部材20の光源取付面21に重合されるフランジ部41aを備えている。このホルダー部41の中央部には、前記半導体型光源10のドーム状カバー10cおよび板ばね31の後側のばね片31bが露出可能な平面方形の開窓部41bが形成されている。また、この開窓部41bの左右側縁部には、前記半導体型光源10の基板10Aの上面の左右側縁部に設けた光源側端子10bに電気的に導通可能な各一対の板ばね端子41cを備えている。   The holder portion 41 is formed in a flat rectangular shape, and includes a flange portion 41 a that is formed in a stepped shape integrally with the peripheral portion thereof and is superposed on the light source mounting surface 21 of the heat sink member 20. At the center of the holder portion 41, a flat rectangular opening portion 41b is formed in which the dome-shaped cover 10c of the semiconductor light source 10 and the spring piece 31b on the rear side of the leaf spring 31 can be exposed. Further, a pair of leaf spring terminals that can be electrically connected to the light source side terminals 10b provided on the left and right side edge portions of the upper surface of the substrate 10A of the semiconductor-type light source 10 are provided on the left and right side edge portions of the opening portion 41b. 41c.

前記フランジ部41aの左右側部の裏面には、前記光源取付面21に設けられたロケーと孔21aに嵌合するロケートピン41dが一体に突設されている。 On the back surfaces of the left and right side portions of the flange portion 41a , a locating pin 41d that fits into a locator provided on the light source mounting surface 21 and the hole 21a is integrally projected.

前記コネクタ部42は、前記フランジ部41aの後端中央部に灯具後方に向けて直状に突設されている。このコネクタ部42はその上面がフランジ部41aの上面と面一な四角柱状に形成され、従って、該コネクタ部42はフランジ部41aの下面よりも下方に突出している。 The connector part 42 is projected in a straight shape toward the rear of the lamp at the center of the rear end of the flange part 41a . The connector part 42 is formed in a quadrangular prism shape whose upper surface is flush with the upper surface of the flange part 41a . Therefore, the connector part 42 projects downward from the lower surface of the flange part 41a .

一方、前記光源取付面21には、前記コネクタ部42に対応する位置に、該コネクタ部42の略下半部が嵌合する角形溝部29が形成されている。   On the other hand, the light source mounting surface 21 is formed with a rectangular groove 29 in which a substantially lower half of the connector part 42 is fitted at a position corresponding to the connector part 42.

この給電部材40は、前記ホルダー部41を半導体型光源10の基板10Aの周縁部上に被冠し、フランジ部41aのロケートピン41dを前記光源取付面21のロケート孔21aに圧入嵌合すると共に、コネクタ部42を該光源取付面21の角形溝部29に圧入嵌合することにより該光源取付面21に仮固定される。このとき、前記半導体型光源10は、その基板10Aの端子10bに、ホルダー部41のばね端子41cが弾接することによって電気的な接続が行われると共に、該ばね端子41cの押え付けにより光源取付面21に固定される。また、前記板ばね31は、その前側のばね片31aの上端縁がフランジ部41aの前部下面に当接して固定される。一方、前記コネクタ部42は角形溝部29からヒートシンク部材20の灯具後方に突出して配置される。   In the power supply member 40, the holder portion 41 is crowned on the peripheral portion of the substrate 10A of the semiconductor light source 10, and the locating pin 41d of the flange portion 41a is press-fitted into the locating hole 21a of the light source mounting surface 21, The connector portion 42 is temporarily fixed to the light source mounting surface 21 by press-fitting into the rectangular groove portion 29 of the light source mounting surface 21. At this time, the semiconductor-type light source 10 is electrically connected to the terminal 10b of the substrate 10A by elastic contact of the spring terminal 41c of the holder portion 41, and the light source mounting surface is pressed by the spring terminal 41c. 21 is fixed. The leaf spring 31 is fixed by contacting the upper end edge of the spring piece 31a on the front side thereof with the lower surface of the front portion of the flange portion 41a. On the other hand, the connector part 42 is disposed so as to protrude from the square groove part 29 to the rear side of the lamp of the heat sink member 20.

前記固定フレーム50は、所要の剛性を有する金属板材をもって前記給電部材40のホルダー部41の外周縁に外嵌してフランジ部41a上に重合する平面方形の枠形状に形成されている。   The fixed frame 50 is formed in a planar rectangular frame shape that is fitted on the outer peripheral edge of the holder portion 41 of the power supply member 40 with a metal plate having a required rigidity and overlaps on the flange portion 41a.

この固定フレーム50の前,後両側縁の左右側部には、脚片51が下向きに略直角に曲折成形されている。各脚片51の下側部には、それぞれ外側に斜め上向きに突出する係止フック51aが切り起し成形されている。   Leg pieces 51 are bent downward at substantially right angles on the left and right sides of the front and rear side edges of the fixed frame 50. A locking hook 51a that protrudes obliquely upward is cut and raised at the lower side of each leg piece 51.

一方、ヒートシンク部材20の光源取付面21には、前記固定フレーム50の脚片51に対応して上下方向に貫通するスリット21bが形成されている。   On the other hand, the light source mounting surface 21 of the heat sink member 20 is formed with a slit 21 b penetrating in the vertical direction corresponding to the leg piece 51 of the fixed frame 50.

従って、前記固定フレーム50は、上方よりその脚片51を光源取付面21のスリット21bに差し込んで、係止フック51aがスリット21bの途中に形成された顎部21cをくぐり抜けて該顎部21cに係合することによって、給電部材40のフランジ部41a上に装着される。この係止フック51aとスリット21bの顎部21cとの係合を確実に行わせるため、固定フレーム50の左右両側部の中央部分に下側に凸となる湾曲したばね部52が形成され、このばね部52が給電部材40のフランジ部41a面に弾接して撓み変形することによって、前記係止フック51aがスリット21bの顎部21cと係合する方向の付勢力が得られるようにしている。これにより、前記給電部材40と半導体型光源10の光源取付面21上への本固定が行われる。   Accordingly, the fixed frame 50 has its leg piece 51 inserted into the slit 21b of the light source mounting surface 21 from above, and the locking hook 51a passes through the jaw portion 21c formed in the middle of the slit 21b and enters the jaw portion 21c. By being engaged, the power supply member 40 is mounted on the flange portion 41a. In order to ensure engagement between the locking hook 51a and the jaw portion 21c of the slit 21b, a curved spring portion 52 that protrudes downward is formed at the center of the left and right sides of the fixed frame 50. The spring portion 52 is elastically brought into contact with the surface of the flange portion 41a of the power supply member 40 to bend and deform so that a biasing force in a direction in which the locking hook 51a engages with the jaw portion 21c of the slit 21b is obtained. As a result, the power supply member 40 and the semiconductor-type light source 10 are permanently fixed onto the light source mounting surface 21.

前記半導体型光源10のヒートシンク部材20への組付けは次のようにして行われる。   The semiconductor light source 10 is assembled to the heat sink member 20 as follows.

先ず、半導体型光源10をその発光部10aを上向きにして、光源取付面21の嵌合孔28にサブアッセンブリされた台座32の上面に載置し、基板10Aを該台座32上で摺動して、該基板10Aの後端面と左右の側部端面とを、後部ストッパー30Rと側部ストッパー30Sとにそれぞれ面接触により当接してセットする(図3参照)。   First, the semiconductor-type light source 10 is placed on the upper surface of the pedestal 32 sub-assembled in the fitting hole 28 of the light source mounting surface 21 with the light emitting portion 10a facing upward, and the substrate 10A is slid on the pedestal 32. Then, the rear end face and the left and right side end faces of the substrate 10A are set in contact with the rear stopper 30R and the side stopper 30S by surface contact, respectively (see FIG. 3).

次に、嵌合孔28の前側の残余部28aに上方からU字状の板ばね31を、その弾性を利用して該板ばね31が嵌合孔28に底付きするまで圧入する。これにより、前記基板10Aの前端面に板ばね31の後側のばね片31bが弾接して、該基板10Aは前記後部ストッパー30Rと板ばね31とにより前後方向に挟圧されて、光源取付面21上での前後方向の取付位置が規定されると共に、左右の側部ストッパー30Sによって左右方向の取付位置が規定される(図4参照)。   Next, a U-shaped leaf spring 31 is press-fitted into the remaining portion 28a on the front side of the fitting hole 28 from above until the leaf spring 31 bottoms into the fitting hole 28 using its elasticity. As a result, the spring piece 31b on the rear side of the leaf spring 31 is brought into elastic contact with the front end surface of the substrate 10A, and the substrate 10A is sandwiched between the rear stopper 30R and the leaf spring 31 in the front-rear direction, and the light source mounting surface The mounting position in the front-rear direction on 21 is defined, and the mounting position in the left-right direction is defined by the left and right side stoppers 30S (see FIG. 4).

前記半導体型光源10と板ばね31の組付工順は逆であってもよい。即ち、先に板ばね31を嵌合孔28の前側部に圧入して後側のばね片31bを台座32の前端面に弾接させて該嵌合孔28にサブアッセンブリしておき、半導体型光源10の基板10Aを、後部ストッパー30Rと左右ストッパー30Sと板ばね31の後側のばね片31bのガイド片31cとで囲まれた部分に、基板10Aの前端で該ガイド片31cを前方へ押し退けるようにして挿入しても、前述と同様に基板10Aの前後方向および左右方向の組付け位置が正確に定められる。   The assembly order of the semiconductor-type light source 10 and the leaf spring 31 may be reversed. That is, the leaf spring 31 is first press-fitted into the front side portion of the fitting hole 28, and the rear spring piece 31b is elastically contacted with the front end surface of the base 32 to be sub-assembled into the fitting hole 28. The substrate 10A of the light source 10 is pushed forward by the front end of the substrate 10A toward the portion surrounded by the rear stopper 30R, the left and right stopper 30S, and the guide piece 31c of the spring piece 31b on the rear side of the leaf spring 31. Even if it is inserted in this manner, the assembling positions of the substrate 10A in the front-rear direction and the left-right direction can be accurately determined as described above.

このようにして半導体型光源10の位置決めを行った後、給電部材40をそのホルダー部41を前記半導体型光源10の基板10Aの周縁部上に上方から宛ってドーム状カバー10cを開窓部41bにくぐらせ、該ホルダー部41を前記基板10Aの周縁部に被冠した状態で、コネクタ部42を光源取付面21の角形溝部29に圧入嵌合すると共に、ホルダー部41の下面のロケートピン41dを該光源取付面21のロケート孔21aに圧入嵌合する。これにより、ホルダー部41のばね端子41cが前記基板10Aの端子10b上に弾接して給電部材40と半導体型光源10とが電気的に導通すると共に、該基板10Aが光源取付面21上に押え付けられて、半導体型光源10と給電部材40との仮固定が行われる(図5参照)。   After positioning the semiconductor light source 10 in this manner, the dome-shaped cover 10c is opened by placing the power supply member 40 with its holder 41 on the peripheral edge of the substrate 10A of the semiconductor light source 10 from above. The connector portion 42 is press-fitted into the rectangular groove portion 29 of the light source mounting surface 21 while the holder portion 41 is covered with the peripheral edge portion of the substrate 10A, and the locating pin 41d on the lower surface of the holder portion 41 is inserted. Is press-fitted into the locating hole 21 a of the light source mounting surface 21. Thereby, the spring terminal 41c of the holder part 41 is elastically contacted with the terminal 10b of the substrate 10A so that the power supply member 40 and the semiconductor light source 10 are electrically connected, and the substrate 10A is pressed against the light source mounting surface 21. In addition, the semiconductor light source 10 and the power supply member 40 are temporarily fixed (see FIG. 5).

そこで、固定フレーム50を前述のようにその脚片51を光源取付面21のスリット21bに上方より差し込んで、給電部材40のフランジ部41a上に装着して半導体型光源10と給電部材40とを本固定することによって、該半導体型光源10を光源取付面21上に正確に位置決めした状態で、ヒートシンク部材20に対する組付けが終了する(図6参照)。   Therefore, as described above, the leg piece 51 of the fixed frame 50 is inserted into the slit 21b of the light source mounting surface 21 from above and is mounted on the flange portion 41a of the power supply member 40 so that the semiconductor light source 10 and the power supply member 40 are connected. By permanently fixing, the assembly of the semiconductor light source 10 to the heat sink member 20 is completed in a state where the semiconductor light source 10 is accurately positioned on the light source mounting surface 21 (see FIG. 6).

前記リフレクタ11は、以上のようにして半導体型光源10をヒートシンク部材20に組付けた後、前記リフレクタ取付面22上にビス等により締結固定し、もしくはロケートピンとロケート孔とによる位置決め手段の圧入嵌合等によって組付けられる。   After the semiconductor light source 10 is assembled to the heat sink member 20 as described above, the reflector 11 is fastened and fixed to the reflector mounting surface 22 with screws or the like, or press-fitting positioning means using a locate pin and a locate hole. It is assembled by means of a match

以上の構成からなる本実施形態のヘッドランプによれば、ヒートシンク部材20の光源取付面21上に突設したストッパー30に半導体型光源10の一側端面を突当てて面接触させることにより、該光源取付面21上における半導体型光源10の配設基準位置が定められ、このストッパー30とばね部材31との対向的な挟圧によって該半導体型光源10の配設位置が確定されるので、前記従来の給電アタッチメント部材の如き中間媒体がなく、半導体型光源10の組付精度を高めることができる。   According to the headlamp of the present embodiment having the above configuration, the one end face of the semiconductor light source 10 is brought into surface contact with the stopper 30 protruding on the light source mounting surface 21 of the heat sink member 20, thereby The arrangement reference position of the semiconductor light source 10 on the light source mounting surface 21 is determined, and the arrangement position of the semiconductor light source 10 is determined by the opposing clamping pressure between the stopper 30 and the spring member 31. There is no intermediate medium like a conventional power supply attachment member, and the assembly accuracy of the semiconductor light source 10 can be increased.

しかも、前記ストッパー30と半導体型光源10の一側端面との相互接触面の精度を出せばよいので、加工精度管理が容易で半導体型光源10の位置決めを正確に行えて、他のリフレクタ11等との光学的位置関係に狂いを生じることがなく、これにより配光性能を向上することができる。   In addition, since the accuracy of the mutual contact surface between the stopper 30 and one side end surface of the semiconductor light source 10 can be obtained, the processing accuracy can be easily managed, and the positioning of the semiconductor light source 10 can be performed accurately. In this way, the optical positional relationship is not deviated and the light distribution performance can be improved.

ここで、特に本実施形態にあっては、前記ストッパー30を、半導体型光源10の基板10Aの後側端面が面接触して当接する後部ストッパー30Rと、該基板10Aの左右の側端面が面接触して当接する一対の側部ストッパー30Sとで構成してあって、これらストッパー30R,30Sに囲まれた部分に前記基板10Aを挿入,載置し、ばね部材としてU字状の板ばね31を、光源取付面21の嵌合孔28(余剰部28a)に嵌挿圧入して、基板10Aを後部ストッパー30Rと板ばね31とにより前後方向に挟圧定置するようにしている。従って、ヒートシンク部材20に形成されたシェード23と、半導体型光源10との前後方向の位置精度を高められることは勿論、左右の側部ストッパー30Sによって左右方向の位置精度も高められ、シェード23と半導体型光源10およびリフレクタ11との光学的な位置関係を設計通りに行えて、配光性能を一段と向上することができる。   Here, particularly in the present embodiment, the stopper 30 includes a rear stopper 30R in which the rear end surface of the substrate 10A of the semiconductor light source 10 comes into contact with the surface and the left and right side end surfaces of the substrate 10A are surfaces. A pair of side stoppers 30S that come into contact with and come into contact with each other. The substrate 10A is inserted and placed in a portion surrounded by the stoppers 30R and 30S, and a U-shaped leaf spring 31 is used as a spring member. Is inserted into the fitting hole 28 (the surplus portion 28a) of the light source mounting surface 21, and the substrate 10A is clamped and fixed in the front-rear direction by the rear stopper 30R and the leaf spring 31. Therefore, the position accuracy in the front-rear direction between the shade 23 formed on the heat sink member 20 and the semiconductor-type light source 10 can be increased, and the position accuracy in the left-right direction can be increased by the left and right side stoppers 30S. The optical positional relationship between the semiconductor light source 10 and the reflector 11 can be performed as designed, and the light distribution performance can be further improved.

また、この半導体型光源10の前記光源取付面21上への固定は半導体型光源10と電気的に接続される給電部材40と固定フレーム50とによって行われ、該給電部材40は、半導体型光源10の周縁部を上方から押え付ける平板状のホルダー部41の一側端に一体に突設したコネクタ部42を四角柱状として、これを前記光源取付面21に形成した角形溝部29に圧入嵌合してあるので、該コネクタ部42を角形溝部29で補剛できて、電源側コネクタ43の着脱時におけるコネクタ部42の変形また破損を防止できて、品質感を高めることができる。しかも、該コネクタ部42の端部は、ヒートシンク部材20の側方、例えば後側方に突出して配置してあるため、前記電源側コネクタ43の着脱作業を灯具後方から容易に行えて作業性を高められると共に、該電源側コネクタ43の振動等による脱落を回避することもできて、より一層品質感および信頼性を高めることができる。   The semiconductor light source 10 is fixed onto the light source mounting surface 21 by a power supply member 40 and a fixed frame 50 electrically connected to the semiconductor light source 10, and the power supply member 40 is a semiconductor light source. A connector portion 42 integrally projecting from one side end of a flat plate-shaped holder portion 41 that presses the peripheral edge portion of the plate 10 from above is formed into a quadrangular prism shape, and this is press-fitted into a rectangular groove portion 29 formed on the light source mounting surface 21. Therefore, the connector portion 42 can be stiffened by the rectangular groove portion 29, and deformation or breakage of the connector portion 42 when the power supply side connector 43 is attached / detached can be prevented, thereby improving the quality. Moreover, since the end portion of the connector portion 42 is disposed so as to protrude to the side of the heat sink member 20, for example, the rear side, the work for attaching and detaching the power source side connector 43 can be easily performed from the rear of the lamp. In addition, the power supply side connector 43 can be prevented from falling off due to vibration or the like, and the quality and reliability can be further enhanced.

更に、前記実施形態のように、ヒートシンク部材20の光源取付面21上への半導体型光源10,板ばね31,給電部材40,および固定フレーム50の組付けを、順次上方からの挿入または圧入操作で行えて締結部材を不要とすることができるため、組付作業を簡素化して作業性を向上できることは勿論、ロボットによる組付けの自動化を容易にすることができる利点がある。   Further, as in the above-described embodiment, the assembly of the semiconductor light source 10, the leaf spring 31, the power feeding member 40, and the fixed frame 50 on the light source mounting surface 21 of the heat sink member 20 is sequentially inserted or press-fitted from above. Since the fastening member is unnecessary, the assembly work can be simplified to improve workability, and there is an advantage that the assembly by the robot can be easily automated.

なお、前記実施形態では、半導体型光源10の出射光を1つのリフレクタ11で灯具前方に向けて反射させる構造を例示したが、複数個のリフレクタにより灯具前方に向けて多段に反射させる構造であってもよく、また、プロジェクタタイプ以外の灯具構成にも適用することが可能である。   In the above embodiment, the structure in which the light emitted from the semiconductor-type light source 10 is reflected by the single reflector 11 toward the front of the lamp is illustrated. However, the structure is a structure in which a plurality of reflectors reflect the light from the front of the lamp in multiple stages.
