Abstract

PROBLEM TO BE SOLVED: To provide a vehicle lamp able to be assembled without increasing assembling man-hours or cost and attaining uniform light emission along a whole area in an arrangement direction of light-emitting elements.SOLUTION: In a vehicle lamp 1 wherein a flat substrate 5 and a plurality of LEDs (light-emitting elements) 6 mounted on the flat substrate 5 are stored in a lamp chamber 4 defined by a housing 2 and an outer lens 3 for covering an opening of the housing, light guide inner lenses 7A for guiding light emitted from the respective LEDs 6 to an outer lens 3 side are arranged for the respective LEDs 6, and a height of each light guide inner lens 7A is determined so as to make constant a spacing between a tip of each of the plurality of light guide inner lenses 7A and the outer lens 3.

Description

本発明は、光源としてＬＥＤ等の複数の発光素子を使用する車両用灯具に関するものである。   The present invention relates to a vehicular lamp that uses a plurality of light emitting elements such as LEDs as a light source.

例えば、ハイマウントストップランプは、車両の車体後部やトランクリッド上面、ルーフパネルの後端上面部等に設置されるが、その一例を図３に示す。   For example, the high-mount stop lamp is installed at the rear of the vehicle body, the upper surface of the trunk lid, the upper surface of the rear end of the roof panel, etc., and an example thereof is shown in FIG.

即ち、図３はハイマウントストップランプの平断面図であり、図示のハイマウントストップランプ１０１は、横方向（図３の上下方向）に長いハウジング１０２とその開口部を覆う凸曲面状のアウタレンズ１０３によって画成された灯室１０４内に、横方向に長い基板１０５と、該基板１０５に横方向に適当な間隔で実装された複数のＬＥＤ（発光ダイオード）１０６を収容して構成されている。ここで、各ＬＥＤ１０６は、リード線１１０を基板１０５に差し込み、その差込部をハンダ付けして固着することによって基板１０５に実装されている。   3 is a plan sectional view of a high-mount stop lamp. The illustrated high-mount stop lamp 101 includes a housing 102 that is long in the lateral direction (vertical direction in FIG. 3) and a convex curved outer lens 103 that covers the opening. In the lamp chamber 104 defined by the above, a substrate 105 that is long in the horizontal direction and a plurality of LEDs (light emitting diodes) 106 that are mounted on the substrate 105 at appropriate intervals in the horizontal direction are accommodated. Here, each LED 106 is mounted on the substrate 105 by inserting the lead wire 110 into the substrate 105 and soldering and fixing the insertion portion.

しかしながら、凸曲面状に湾曲するアウタレンズ１０３を備えるハイマウントストップランプ１０１において、基板１０５上に複数のＬＥＤ１０６を横方向に直線状に配列する構成を採用すると、各ＬＥＤ１０６とアウタレンズ１０３との間隔が不均一となり、横方向全体に亘って均一な発光を得ることができないという問題がある。   However, in the high-mount stop lamp 101 including the outer lens 103 that is curved in a convex curved surface, if a configuration in which a plurality of LEDs 106 are linearly arranged on the substrate 105 is employed, the distance between the LEDs 106 and the outer lens 103 is inconsistent. There is a problem that uniform light emission cannot be obtained over the entire lateral direction.

そこで、特許文献１には、図４及び図５に示すような車両用灯具が提案されている。   Therefore, Patent Document 1 proposes a vehicular lamp as shown in FIGS. 4 and 5.

即ち、図４は特許文献１において提案された車両用灯具の平断面図、図５は図４のＢ−Ｂ線断面図であり、図示の車両用灯具２０１はハイマウントストップランプであって、これも横方向（図４の左右方向）に長いハウジング２０２とその開口部を覆う凸曲面状のアウタレンズ２０３によって画成された灯室２０４内に、横方向に長い基板２０５と、該基板２０５に横方向に適当な間隔で実装された複数のＬＥＤ（発光ダイオード）２０６を収容して構成されている。   That is, FIG. 4 is a plan sectional view of the vehicle lamp proposed in Patent Document 1, FIG. 5 is a sectional view taken along line BB in FIG. 4, and the illustrated vehicle lamp 201 is a high-mount stop lamp. Also in the lamp chamber 204 defined by the housing 202 that is long in the lateral direction (left and right in FIG. 4) and the convex curved outer lens 203 that covers the opening, a substrate 205 that is long in the lateral direction, A plurality of LEDs (light emitting diodes) 206 mounted at appropriate intervals in the horizontal direction are accommodated.

ここで、基板２０５は、１枚の平板を扇状型で打ち抜きして得られたものであって、アウタレンズ２０３の曲面形状に合わせて横長円弧状帯板として構成されており、灯室２０４内に水平に取り付けて収容されている。そして、この基板２０５に複数のＬＥＤ２０６が図５に示すようにＬ字状に屈曲するリード線２１０によって取り付けられている。このように構成することによって、各ＬＥＤ２０６とアウタレンズ２−３との間隔が一定になるため、横方向全域に亘って均一な発光を得ることができる。   Here, the substrate 205 is obtained by punching out a single flat plate with a fan shape, and is configured as a horizontally long arc-shaped strip in accordance with the curved surface shape of the outer lens 203. It is stored horizontally. A plurality of LEDs 206 are attached to the substrate 205 by lead wires 210 bent in an L shape as shown in FIG. With this configuration, the distance between each LED 206 and the outer lens 2-3 is constant, so that uniform light emission can be obtained over the entire lateral direction.

しかしながら、特許文献１において提案された図４及び図５に示す車両用灯具２０１においては、ＬＥＤ２０６を基板２０５に実装する前に該ＬＥＤ２０６のリード線２１０をＬ字状に屈曲するフォーミング工程が必要である他、Ｌ字状に屈曲するリード線２１０を備えるＬＥＤ２０６を自動実装機によって基板２０５上に自動的に実装することができないため、実際には作業者が手作業でＬＥＤ２０６を並べて実装する必要があり、組立工数が増えてコストアップを招くという問題がある。   However, in the vehicle lamp 201 shown in FIG. 4 and FIG. 5 proposed in Patent Document 1, a forming process for bending the lead wire 210 of the LED 206 into an L shape before the LED 206 is mounted on the substrate 205 is necessary. In addition, since the LED 206 including the lead wire 210 bent in an L shape cannot be automatically mounted on the substrate 205 by an automatic mounting machine, it is actually necessary for the operator to manually mount the LEDs 206 side by side. There is a problem that the number of assembling steps increases and the cost increases.

本発明は上記事情に鑑みてなされたもので、その目的とする処は、組立工数の増加やコストアップを招くことなく組み立てることができるとともに、発光素子の配列方向全域に亘って均一な発光を得ることができる車両用灯具を提供することにある。   The present invention has been made in view of the above circumstances, and the target process is that it can be assembled without increasing the number of assembling steps or increasing the cost, and can emit light uniformly over the entire arrangement direction of the light emitting elements. An object of the present invention is to provide a vehicular lamp that can be obtained.

上記目的を達成するため、請求項１記載の発明は、ハウジングとその開口部を覆うアウタレンズによって画成される灯室内に、平面基板と、該平面基板に実装された複数の発光素子を収容して成る車両用灯具において、前記各発光素子から出射される光を前記アウタレンズ側に導く導光インナレンズを各発光素子毎に配設し、複数の前記導光インナレンズの各先端と前記アウタレンズとの間隔が一定となるよう各導光インナレンズの高さを設定したことを特徴とする。   In order to achieve the above object, according to the first aspect of the present invention, a flat substrate and a plurality of light emitting elements mounted on the flat substrate are accommodated in a lamp chamber defined by a housing and an outer lens covering the opening. A light guide inner lens that guides the light emitted from each light emitting element to the outer lens side is disposed for each light emitting element, and each tip of the plurality of light guide inner lenses, the outer lens, The height of each of the light guide inner lenses is set so that the distance between them is constant.

請求項２記載の発明は、請求項１記載の発明において、前記発光素子を砲弾型ＬＥＤで構成するとともに、前記導光インナレンズの各先端部を砲弾形状としたことを特徴とする。   The invention according to claim 2 is characterized in that, in the invention according to claim 1, the light emitting element is constituted by a bullet-type LED, and each tip portion of the light guide inner lens is bullet-shaped.

請求項３記載の発明は、請求項１記載の発明において、前記複数の導光インナレンズは、灯具の横方向に沿って隣り合うように形成され、該複数の導光インナレンズの高さは、隣り合う導光インナレンズの間でそれぞれ異なることを特徴とする。   According to a third aspect of the present invention, in the first aspect of the invention, the plurality of light guide inner lenses are formed so as to be adjacent to each other along the lateral direction of the lamp, and the height of the plurality of light guide inner lenses is The adjacent light guide inner lenses are different from each other.

本発明によれば、各発光素子から出射される光をアウタレンズ側に導く導光インナレンズを各発光素子毎に灯室内に配設したため、平面基板上に実装された発光素子とアウタレンズとの距離が一定でない場合であっても、複数の導光インナレンズの各先端とアウタレンズとの間隔が一定となるよう各導光インナレンズの高さを設定することによって、各導光インナレンズの先端から出射してアウタレンズを通過する光の強度を同じにすることができ、発光素子の配列方向全域に均一な発光を得ることができる。   According to the present invention, the light guide inner lens that guides the light emitted from each light emitting element to the outer lens side is disposed in the lamp chamber for each light emitting element, and therefore, the distance between the light emitting element mounted on the flat substrate and the outer lens. Even if is not constant, by setting the height of each light guide inner lens so that the distance between each tip of the plurality of light guide inner lenses and the outer lens is constant, from the tip of each light guide inner lens The intensity of the light emitted and passing through the outer lens can be made the same, and uniform light emission can be obtained throughout the arrangement direction of the light emitting elements.

又、複数の発光素子は、自動実装機を用いて平面基板上に自動的に実装されるため、当該車両用灯具の組み立てを組立工数の増加やコストアップを招くことなく効率良く行うことができる。   In addition, since the plurality of light emitting elements are automatically mounted on the flat substrate using an automatic mounting machine, the vehicle lamp can be efficiently assembled without increasing the number of assembly steps or increasing the cost. .

更に、発光素子を砲弾型ＬＥＤで構成するとともに、導光インナレンズの各先端部を砲弾型ＬＥＤの先端形状に合わせて砲弾形状としたため、見た目にはあたかも砲弾型ＬＥＤから光が直接出射しているかのようなイメージとなり、導光インナレンズを用いたことによる意匠性の低下が防がれる。   In addition, the light emitting element is composed of a bullet-type LED, and each tip portion of the light guide inner lens is formed into a bullet shape according to the tip shape of the bullet-type LED, so that the light is emitted directly from the bullet-type LED. As a result, it is possible to prevent the design from being deteriorated by using the light guide inner lens.

以下に本発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１は本発明に係る車両用灯具の平断面図、図２は図１のＡ−Ａ線断面図であり、図示の車両用灯具１は、ハウジング２とその開口部を覆う透明なアウタレンズ３によって画成された灯室４内に、平坦な平面基板５と、該平面基板５上に横方向（図１の左右方向）に適当な間隔で実装された複数（図示例では、６つ）の砲弾型ＬＥＤ（以下、単にＬＥＤと称する）６と、導光レンズユニット７及びエクステンション８を収容して構成されている。   FIG. 1 is a cross-sectional plan view of a vehicular lamp according to the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and the vehicular lamp 1 shown in the figure is a transparent outer lens 3 covering a housing 2 and its opening. In the lamp chamber 4 defined by the above, a flat planar substrate 5 and a plurality (six in the illustrated example) mounted on the planar substrate 5 at appropriate intervals in the lateral direction (left-right direction in FIG. 1). A bullet-type LED (hereinafter simply referred to as LED) 6, a light guide lens unit 7 and an extension 8 are accommodated.

上記アウタレンズ３は、その光出射面が斜面を成し、その高さは図１の右側から左方向に沿って次第に低くなっている。従って、このアウタレンズ３と各ＬＥＤ６との間隔は横方向に一定ではなく、図１の右側に行くに従って次第に大きくなっている。このため、そのままでは（導光レンズユニット７を用いない場合には）、アウタレンズ３から出射される光の強度は右方向に沿って次第に低下し、横方向全域に亘って均一な発光を得ることができない。   The light exit surface of the outer lens 3 forms a slope, and its height gradually decreases from the right side in FIG. 1 along the left direction. Therefore, the distance between the outer lens 3 and each LED 6 is not constant in the lateral direction, and gradually increases toward the right side of FIG. Therefore, as it is (when the light guide lens unit 7 is not used), the intensity of the light emitted from the outer lens 3 gradually decreases along the right direction, and uniform light emission can be obtained over the entire lateral direction. I can't.

ところで、本実施の形態では、平面基板５はＬＥＤ６の実装面がアウタレンズ３側に向かうよう縦方向に起立した状態で２本のビス９によってハウジング２の内面に取り付けられている。そして、この平面基板５には、各ＬＥＤ６から延びる２本のリード線１０を折り曲げることなくそのまま差し込み、その差込部をハンダ付けすることによって各ＬＥＤ６が不図示の自動実装機によって自動的に実装される。   By the way, in the present embodiment, the flat substrate 5 is attached to the inner surface of the housing 2 with the two screws 9 in a state where the mounting surface of the LED 6 stands in the vertical direction so as to face the outer lens 3 side. Then, the two lead wires 10 extending from each LED 6 are inserted as they are into the flat substrate 5 without being bent, and each LED 6 is automatically mounted by an automatic mounting machine (not shown) by soldering the insertion portion. Is done.

又、前記導光レンズユニット７は、その一端に形成された差込リブをハウジング２に形成された係合溝２ａに差し込み、他端をビス１１によってハウジング２に締め付けることによってハウジング２に固定されているが、各ＬＥＤ６に対向する箇所には円柱状の計６本の導光インナレンズ７Ａがアウタレンズ３に向かって突出するよう一体に形成されている。ここで、複数の導光インナレンズ７Ａは、その先端とアウタレンズ３との距離が一定になるよう高さが設定されている。具体的には、導光インナレンズ７Ａは、図１の右側のものほど高さが高くなるよう設定されている。又、各導光インナレンズ７Ａの各ＬＥＤ６に対向する面は凹状の光入射面とされ、先端部はＬＥＤ６の砲弾形状に合わせて砲弾形状とされている。   The light guide lens unit 7 is fixed to the housing 2 by inserting an insertion rib formed at one end thereof into an engaging groove 2 a formed in the housing 2 and fastening the other end to the housing 2 with a screw 11. However, a total of six light guide inner lenses 7A in a columnar shape are integrally formed so as to protrude toward the outer lens 3 at locations facing each LED 6. Here, the height of the plurality of light guide inner lenses 7 </ b> A is set so that the distance between the tip and the outer lens 3 is constant. Specifically, the light guide inner lens 7 </ b> A is set so that its height increases toward the right side in FIG. 1. Further, the surface of each light guide inner lens 7 </ b> A facing each LED 6 is a concave light incident surface, and the tip is formed in a bullet shape in accordance with the bullet shape of the LED 6.

更に、前記エクステンション８は、複数の導光インナレンズ７Ａの周囲の隙間を覆うように配置されており、各導光インナレンズ７Ａの先端部が貫通するする部分の周囲には凹曲面状の反射面８ａがそれぞれ形成されている。   Furthermore, the extension 8 is disposed so as to cover the gaps around the plurality of light guide inner lenses 7A, and a concave curved reflection is formed around the portion where the tip of each light guide inner lens 7A penetrates. Each surface 8a is formed.

而して、複数のＬＥＤ６に不図示の電源から電流が供給されてこれらのＬＥＤ６が起動されると、各ＬＥＤ６から出射する光は、導光レンズユニット７の対応する導光インナレンズ７Ａの光入射面から導光インナレンズ７Ａ内に入射し、該導光インナレンズ７Ａ内を全反射しながら先端方向に進み、導光インナレンズ７Ａの先端から出射し、エクステンション８の反射面８ａで反射してアウタレンズ３を通過して図１の上方に向かって照射される。尚、各導光インナレンズ７Ａの光入射面から導光インナレンズ７Ａ内に入射しなかった光は、エクステンション８の背面によって遮られて外部に漏れることがない。   Thus, when a current is supplied to the plurality of LEDs 6 from a power source (not shown) and these LEDs 6 are activated, the light emitted from each LED 6 is the light of the corresponding light guide inner lens 7A of the light guide lens unit 7. The light enters the light guide inner lens 7A from the incident surface, proceeds in the tip direction while being totally reflected in the light guide inner lens 7A, is emitted from the tip of the light guide inner lens 7A, and is reflected by the reflection surface 8a of the extension 8. Then, the light passes through the outer lens 3 and is irradiated upward in FIG. The light that has not entered the light guide inner lens 7A from the light incident surface of each light guide inner lens 7A is blocked by the back surface of the extension 8 and does not leak outside.

以上において、本実施の形態に係る車両用灯具１においては、各ＬＥＤ６から出射される光をアウタレンズ３側に導く導光インナレンズ７Ａを各ＬＥＤ６毎に灯室４内に配設したため、平面基板５上に実装されたＬＥＤ６とアウタレンズ３との距離が一定でない場合であっても、複数の導光インナレンズ７Ａの各先端とアウタレンズ３との間隔が一定となるよう各導光インナレンズ７Ａの高さを設定することによって、各導光インナレンズ７Ａの先端から出射してアウタレンズ３を通過する光の強度を同じにすることができ、複数のＬＥＤ６の配列方向（横方向）全域に亘って均一な発光を得ることができる。   In the above, in the vehicular lamp 1 according to the present embodiment, since the light guide inner lens 7A that guides the light emitted from each LED 6 to the outer lens 3 side is disposed in the lamp chamber 4 for each LED 6, a flat substrate 5, even if the distance between the LED 6 mounted on the outer lens 3 and the outer lens 3 is not constant, each light guide inner lens 7 </ b> A has a constant distance between each tip of the plurality of light guide inner lenses 7 </ b> A and the outer lens 3. By setting the height, the intensity of the light emitted from the tip of each light guide inner lens 7A and passing through the outer lens 3 can be made the same, and the entire array direction (lateral direction) of the plurality of LEDs 6 is extended. Uniform light emission can be obtained.

又、複数のＬＥＤ６は、自動実装機を用いて平面基板５上に自動的に実装されるため、当該車両用灯具１の組み立てを組立工数の増加やコストアップを招くことなく効率良く行うことができる。   Further, since the plurality of LEDs 6 are automatically mounted on the flat substrate 5 using an automatic mounting machine, the vehicle lamp 1 can be efficiently assembled without increasing the number of assembly steps or increasing the cost. it can.

更に、本実施の形態では、ＬＥＤ６を砲弾型ＬＥＤで構成するとともに、各導光インナレンズ７Ａの各先端部を砲弾型ＬＥＤ６の先端形状に合わせて砲弾形状としたため、見た目にはあたかも砲弾型ＬＥＤ６から光が直接出射しているかのようなイメージとなり、当該車両用灯具１の導光インナレンズを７Ａ用いたことによる意匠性の低下が防がれる。   Further, in the present embodiment, the LED 6 is formed of a bullet-type LED, and each tip portion of each light guide inner lens 7A is formed in a bullet shape according to the tip shape of the bullet-type LED 6, so that it looks as if it is a bullet-type LED 6 Thus, the image is as if the light is directly emitted from the light, and the deterioration of the design due to the use of the light guide inner lens 7A of the vehicular lamp 1 is prevented.

尚、以上の実施の形態では、発光素子として砲弾型ＬＥＤを使用したが、発光素子としてはＬＥＤの他にレーザーダイオード等を使用することができる。   In the above embodiment, the bullet-type LED is used as the light emitting element, but a laser diode or the like can be used as the light emitting element in addition to the LED.
