Description

本考案は、車幅灯に関する。   The present invention relates to a vehicle width lamp.

トラック等の車体の両側には、トラックの存在を知らしめるための車幅灯(サイドマーカー)が複数個取り付けられている。近年、このような車幅灯の光源としてLEDを用いたものが種々提案されている。例えば、特許文献1に開示のサイドマーカーユニットは、ドーム状のカバーと、カバーにより覆われる取付枠と、取付枠に取り付けられたLEDからなる第1光源及び第2光源と、を備える。カバーには下向きの透光窓が設けられ、レンズを保持するレンズホルダが透光窓に装着されている。第1光源から発せられた光は歩行者等に車両の存在を知らせる役割を果たす。一方、第2光源から発せられた光はレンズを介して路面を照らし、運転手はタイヤが通過する路面状況等を良好に確認することができる。   A plurality of vehicle width lights (side markers) are attached to both sides of a vehicle body such as a truck to notify the presence of the truck. In recent years, various types of light sources using such LEDs have been proposed. For example, the side marker unit disclosed in Patent Document 1 includes a dome-shaped cover, an attachment frame covered with the cover, and a first light source and a second light source including LEDs attached to the attachment frame. The cover is provided with a downward transparent window, and a lens holder for holding the lens is attached to the transparent window. The light emitted from the first light source plays a role of notifying a pedestrian or the like of the presence of the vehicle. On the other hand, the light emitted from the second light source illuminates the road surface through the lens, so that the driver can satisfactorily confirm the road surface condition through which the tire passes.

実用新案登録第3138009号Utility Model Registration No. 3138209

上述した従来のサイドマーカーユニットは、カバーに透光窓を設けてレンズを装着させる等、構成が複雑になるという問題があった。また、第1光源からの光は主に車両の側方に向かって照射され、第2光源からの光は下方に向かって照射されるため、歩行者等が車体の側方にいる場合には第1光源から発せられた光によって車両の存在を比較的容易に認識することができるものの、歩行者等が車体の前方や後方にいる場合にはサイドマーカーユニットからの光が見えづらく、車両の存在を認識させるには十分とはいえなかった。   The conventional side marker unit described above has a problem that the configuration is complicated, such as providing a light-transmitting window on the cover and attaching a lens. In addition, the light from the first light source is mainly emitted toward the side of the vehicle, and the light from the second light source is emitted downward, so when a pedestrian or the like is on the side of the vehicle body Although the presence of the vehicle can be recognized relatively easily by the light emitted from the first light source, it is difficult to see the light from the side marker unit when a pedestrian or the like is in front of or behind the vehicle body. It was not enough to make people aware.

本考案は、簡単な構成で周囲を照らすことのできる車幅灯の提供を目的とする。   An object of the present invention is to provide a vehicle width lamp that can illuminate the surroundings with a simple configuration.

本発明に係る車幅灯は、座部と、前記座部に支持された第1光源及び第2光源と、前記座部に装着されて前記第1光源及び前記第2光源を覆う透光カバーと、を備え、前記座部は、基部と、前記基部から所定方向に延出する延出部と、を有し、前記基部に前記第1光源が配置され、前記延出部の先端部に前記第2光源が配置され、前記第1光源は第1LEDを有し、前記第1LEDの光軸は前記所定方向と平行であり、前記第2光源は、前記延出部の長手方向中心軸を中心とする円周方向に沿って配列された複数個の第2LEDを有し、前記第2光源からの光は、前記所定方向に対して傾斜する方向に向けて放射状に照射される。   The vehicle width lamp according to the present invention includes a seat portion, a first light source and a second light source supported by the seat portion, and a translucent cover that is attached to the seat portion and covers the first light source and the second light source. And the seat has a base and an extension extending from the base in a predetermined direction, the first light source is disposed on the base, and a tip of the extension The second light source is disposed, the first light source includes a first LED, an optical axis of the first LED is parallel to the predetermined direction, and the second light source has a longitudinal central axis of the extension portion. It has several 2nd LED arranged along the circumference direction used as the center, and the light from the said 2nd light source is irradiated radially toward the direction inclined with respect to the said predetermined direction.

本発明に係る車幅灯では、前記第1光源が有する前記第1LEDの光軸は前記所定方向と平行であり、前記第2光源からの光は、前記所定方向に対して傾斜する方向に向けて放射状に照射されるので、車幅灯が車両の側面に設置された状態において、第1光源からの光により車両の側方を明るく照らすことができると共に、第2光源からの光によって下方及び車両の前後方向を明るく照らすことができるので、車両の前後方向に対しても車両の存在を良好に知らしめることができる。   In the vehicle width lamp according to the present invention, the optical axis of the first LED of the first light source is parallel to the predetermined direction, and the light from the second light source is directed in a direction inclined with respect to the predetermined direction. Therefore, the side of the vehicle can be brightly illuminated by the light from the first light source and the light from the second light source can be illuminated downward and Since the front-rear direction of the vehicle can be brightly illuminated, the presence of the vehicle can be well known in the front-rear direction of the vehicle.

Second LED 42.

より具体的に、延出部7は、本体70と、本体70の先端面70aから所定方向D1に延出する先端部71と、を有し、延出部71は先端に向かうに従い縮径している。また、延出部71にはLEDユニット40(基板41)を支持するための支持部72が、中心軸C1を中心とする円周方向D2に等間隔で設けられている。各支持部72は、延出部7の中心軸C1を中心とする円周方向D2に間隔を空けて設けられた一対の側支持爪72a,72aと、一対の側支持爪72a,72aよりも延出部7の径方向外方に位置する一対の下支持爪72b,72bと、を有する。基板41は、一対の側支持爪72a、72aと一対の下支持爪72b,72bの間に挿入され、その下端41aが本体70の先端面70aに当接されて位置決めされて固定される。   More specifically, the extending part 7 has a main body 70 and a front end part 71 extending from the front end surface 70a of the main body 70 in the predetermined direction D1, and the extending part 71 is reduced in diameter toward the front end. ing. Further, support portions 72 for supporting the LED unit 40 (substrate 41) are provided in the extending portion 71 at equal intervals in the circumferential direction D2 with the central axis C1 as the center. Each support part 72 is more than a pair of side support claws 72a and 72a and a pair of side support claws 72a and 72a provided at intervals in the circumferential direction D2 centering on the central axis C1 of the extension part 7. A pair of lower support claws 72b, 72b positioned radially outward of the extending portion 7; The substrate 41 is inserted between the pair of side support claws 72a and 72a and the pair of lower support claws 72b and 72b, and the lower end 41a thereof is abutted against the front end surface 70a of the main body 70 and positioned and fixed.

これにより、第2光源4が備える複数個の第2LED42は、延出部7の中心軸C1を中心とする円周方向に沿って等間隔で配列され、また各第2LED42の光軸C3は、中心軸C1(第1LED32の光軸C2)に対して所定の傾斜角度αで傾斜する。   Accordingly, the plurality of second LEDs 42 included in the second light source 4 are arranged at equal intervals along the circumferential direction centering on the central axis C1 of the extending portion 7, and the optical axis C3 of each second LED 42 is It inclines with the predetermined | prescribed inclination | tilt angle (alpha) with respect to the central axis C1 (optical axis C2 of 1st LED32).

図2を参照して、第1光源3と第2光源4は第1リード線L1を介して電気的に並列接続され、このリード線L1は延出部7に螺旋状に巻かれて延びている。また、第2光源4は第2リード線L2を介して図示しない外部の駆動用回路に接続され、この第2リード線L2は延出部7の内部空間とゴム栓8の貫通孔80を通って外部に引き出されている。なお、図3ではリード線L1,L2を省略している。   Referring to FIG. 2, the first light source 3 and the second light source 4 are electrically connected in parallel via the first lead wire L <b> 1, and the lead wire L <b> 1 extends in a spiral manner around the extension portion 7. Yes. The second light source 4 is connected to an external driving circuit (not shown) via the second lead wire L2, and the second lead wire L2 passes through the internal space of the extending portion 7 and the through hole 80 of the rubber plug 8. Pulled out. In FIG. 3, the lead wires L1 and L2 are omitted.

このように構成された車幅灯1は、中心軸C1(所定方向D1)が水平となる横向き姿勢で車両の側面に装着される。そして、第1光源3からの光は投光カバー5により拡散されて、主に中心軸C1に沿った方向に(即ち、車両の側方に向かって)照射される。これにより、車両の側方にいる歩行者等に車両の存在を知らせることができる。一方、第2光源4からの光は透光カバー5により拡散され、所定方向D1に対して傾斜する方向(投光カバー5の略径方向外方)に向かって放射状に照射される。このとき、一部の光は路面を照らし、これによって運転手はタイヤが通過する路面状況を確認することができ、また他の一部の光は車両の前方又は後方に向かって照射され、これによって車両の前方又は後方にいる歩行者等に車両の存在を知らせることができる。   The thus configured vehicle width lamp 1 is mounted on the side surface of the vehicle in a lateral posture in which the central axis C1 (predetermined direction D1) is horizontal. And the light from the 1st light source 3 is diffused by the light projection cover 5, and is mainly irradiated to the direction along the central axis C1 (namely, toward the side of a vehicle). Thereby, the presence of the vehicle can be notified to a pedestrian or the like on the side of the vehicle. On the other hand, the light from the second light source 4 is diffused by the translucent cover 5 and irradiated radially in a direction inclined with respect to the predetermined direction D1 (substantially radially outward of the light projecting cover 5). At this time, a part of the light illuminates the road surface, so that the driver can check the road surface condition through which the tire passes, and another part of the light is emitted toward the front or rear of the vehicle. By this, the presence of the vehicle can be notified to a pedestrian or the like in front of or behind the vehicle.

ここで、第2光源4(第2LED42)の光軸C2の所定方向D1に対する傾斜角度αは68°〜72°であるのが好ましく、70°程度であるのがより好ましい。傾斜角度αが大きすぎても小さすぎても車幅灯1によって照らせる範囲が狭くなってしまうためである。   Here, the inclination angle α of the optical axis C2 of the second light source 4 (second LED 42) with respect to the predetermined direction D1 is preferably 68 ° to 72 °, more preferably about 70 °. This is because if the inclination angle α is too large or too small, the range that can be illuminated by the vehicle width lamp 1 becomes narrow.

また、複数個の第1LED32と複数個の第2LED42とは、中心線C1を中心とする円周方向D2において重ならないように(即ち、円周方向D2において隣接する一対のLED32,32の間に第2LED42が位置するように)配置するのが好ましい。このような配置とすることにより、車幅灯1全体をより均一に光らせることができる。   The plurality of first LEDs 32 and the plurality of second LEDs 42 do not overlap in the circumferential direction D2 centering on the center line C1 (that is, between a pair of LEDs 32, 32 adjacent in the circumferential direction D2). It is preferably arranged (so that the second LED 42 is located). By setting it as such arrangement | positioning, the whole vehicle width lamp 1 can be made to shine more uniformly.

このように、本実施形態に係る車幅灯1によれば、車両の側方及び下方に加え、車両の前方及び後方に向かって光を照射できるので、より広範囲にわたって車両の存在を知らしめることができる。   As described above, according to the width lamp 1 according to the present embodiment, light can be emitted toward the front and rear of the vehicle in addition to the side and the lower side of the vehicle, so that the presence of the vehicle can be informed over a wider range. Can do.

以上、本考案の実施形態に係る車幅灯について添付の図面を参照して説明したが、本考案はかかる実施形態に限定されず、本考案の範囲を逸脱することなく種々の変形、修正が可能である。   As mentioned above, although the vehicle width lamp which concerns on embodiment of this invention was demonstrated with reference to attached drawing, this invention is not limited to this embodiment, Various deformation | transformation and correction are carried out without deviating from the scope of this invention. Is possible.
