本発明は、ドアミラー用サイドターンランプ法規配光を満足させるための第１ＬＥＤ光源および第２ＬＥＤ光源と、装飾用配光を形成するための第３ＬＥＤ光源とを具備し、第１ＬＥＤ光源および第２ＬＥＤ光源をドアミラー用サイドターンランプの車両側方側かつ車両後方側の位置に配置し、第１ＬＥＤ光源および第２ＬＥＤ光源を車両前後方向に配列したドアミラー用サイドターンランプに関する。 The present invention comprises a first LED light source and a second LED light source for satisfying a side turn lamp legal light distribution for a door mirror, and a third LED light source for forming a decorative light distribution, the first LED light source and the second LED light source. The door mirror side turn lamp is arranged at positions on the vehicle side and vehicle rear side, and the first LED light source and the second LED light source are arranged in the vehicle front-rear direction.

特に、本発明は、ドアミラー用サイドターンランプ全体の製造コストを抑制しつつ、ＬＥＤ光源からの光の利用効率を向上させることができるドアミラー用サイドターンランプに関する。 In particular, the present invention relates to a door mirror side turn lamp capable of improving the light use efficiency from an LED light source while suppressing the manufacturing cost of the entire door mirror side turn lamp.

従来から、ドアミラー用サイドターンランプ法規配光を満足させるための第１ＬＥＤ光源および第２ＬＥＤ光源と、装飾用配光を形成するための第３ＬＥＤ光源とを具備し、第１ＬＥＤ光源および第２ＬＥＤ光源をドアミラー用サイドターンランプの車両側方側かつ車両後方側の位置に配置し、第１ＬＥＤ光源および第２ＬＥＤ光源を車両前後方向に配列したドアミラー用サイドターンランプが知られている。この種のドアミラー用サイドターンランプの例としては、例えば特許文献１（特開２００５−１９９７９４号公報）の図４などに記載されたものがある。 Conventionally, a first LED light source and a second LED light source for satisfying a side turn lamp legal light distribution for a door mirror and a third LED light source for forming a decorative light distribution are provided, and the first LED light source and the second LED light source are provided. 2. Description of the Related Art A door mirror side turn lamp in which a first LED light source and a second LED light source are arranged in a vehicle front-rear direction, which is disposed at a position on the vehicle side and rear side of the door mirror side turn lamp, is known. An example of this type of side mirror for a door mirror is described in FIG. 4 of Japanese Patent Application Laid-Open No. 2005-199794, for example.

特許文献１の図４に記載されたドアミラー用サイドターンランプでは、水平方向に延びている第１ＬＥＤ光源の光軸と水平方向に延びている第２ＬＥＤ光源の光軸とが互いに平行になるように、第１ＬＥＤ光源および第２ＬＥＤ光源が平面状の基板に実装されている。そのため、特許文献１の図４に記載されたドアミラー用サイドターンランプでは、ドアミラー用サイドターンランプ法規配光を満足させるための第１ＬＥＤ光源と第２ＬＥＤ光源とが、異なる平面内に位置する複数の基板のそれぞれに実装されている特許文献２（特開２００８−２２１９６５号公報）の図３に記載されたドアミラー用サイドターンランプよりも、ドアミラー用サイドターンランプ全体の製造コストを抑制することができる。 In the door mirror side turn lamp described in FIG. 4 of Patent Document 1, the optical axis of the first LED light source extending in the horizontal direction and the optical axis of the second LED light source extending in the horizontal direction are parallel to each other. The first LED light source and the second LED light source are mounted on a planar substrate. Therefore, in the door mirror side turn lamp described in FIG. 4 of Patent Document 1, a plurality of first LED light sources and second LED light sources for satisfying the door mirror side turn lamp law distribution light are located in different planes. The manufacturing cost of the door mirror side turn lamp as a whole can be reduced as compared with the door mirror side turn lamp described in FIG. 3 of Patent Document 2 (Japanese Patent Laid-Open No. 2008-221965) mounted on each of the substrates. .

ところで、ドアミラー用サイドターンランプ法規配光を満足させるためには、車両後方側および車両側方側の広範囲（広角度）に所定の明るさの光を照射する必要がある。特許文献２の図３に記載されたドアミラー用サイドターンランプでは、第１ＬＥＤ光源の光軸と第２ＬＥＤ光源の光軸とが互いに異なる向きに設定されているため、比較的低い輝度を有する第１ＬＥＤ光源および第２ＬＥＤ光源を用いる場合であっても、車両後方側および車両側方側の広範囲（広角度）に十分な明るさの光を照射することができる。 By the way, in order to satisfy the light distribution specified by the side mirror for the door mirror, it is necessary to irradiate light having a predetermined brightness over a wide range (wide angle) on the vehicle rear side and the vehicle side side. In the door mirror side turn lamp described in FIG. 3 of Patent Document 2, since the optical axis of the first LED light source and the optical axis of the second LED light source are set in different directions, the first LED having relatively low luminance is used. Even when the light source and the second LED light source are used, light with sufficient brightness can be irradiated over a wide range (wide angle) on the vehicle rear side and the vehicle side side.

ところが、特許文献１の図４に記載されたドアミラー用サイドターンランプでは、第１ＬＥＤ光源の光軸と第２ＬＥＤ光源の光軸とが互いに平行に設定されており、第１ＬＥＤ光源および第２ＬＥＤ光源から照射された光を配光制御するための手段も特に設けられていない。そのため、特許文献１の図４に記載されたドアミラー用サイドターンランプでは、車両後方側および車両側方側の広範囲（広角度）に十分な明るさの光を第１ＬＥＤ光源および第２ＬＥＤ光源から照射しようとすると、特許文献２の図３に記載されたドアミラー用サイドターンランプよりも高輝度の第１ＬＥＤ光源および第２ＬＥＤ光源を用いなければならない。 However, in the side turn lamp for a door mirror described in FIG. 4 of Patent Document 1, the optical axis of the first LED light source and the optical axis of the second LED light source are set in parallel to each other, and from the first LED light source and the second LED light source, There is no special means for controlling the light distribution of the irradiated light. Therefore, in the side turn lamp for a door mirror described in FIG. 4 of Patent Document 1, light with sufficient brightness is emitted from the first LED light source and the second LED light source over a wide range (wide angle) on the vehicle rear side and vehicle side side. If it tries to do, you have to use the 1st LED light source and 2nd LED light source whose brightness is higher than the side turn lamp for door mirrors described in FIG.

つまり、車両後方側および車両側方側の広範囲（広角度）に第１ＬＥＤ光源および第２ＬＥＤ光源からの光を照射する場合、第１ＬＥＤ光源の光軸と第２ＬＥＤ光源の光軸とが互いに平行に設定されている特許文献１の図４に記載されたドアミラー用サイドターンランプでは、第１ＬＥＤ光源の光軸と第２ＬＥＤ光源の光軸とが互いに異なる向きに設定されている特許文献２の図３に記載されたドアミラー用サイドターンランプよりも、第１ＬＥＤ光源および第２ＬＥＤ光源からの光の利用効率が低くなってしまう。 That is, when irradiating light from the first LED light source and the second LED light source over a wide range (wide angle) on the vehicle rear side and the vehicle side side, the optical axis of the first LED light source and the optical axis of the second LED light source are parallel to each other. In the door mirror side turn lamp described in FIG. 4 of Patent Document 1, the optical axis of the first LED light source and the optical axis of the second LED light source are set in different directions. The use efficiency of light from the first LED light source and the second LED light source is lower than the side turn lamp for door mirror described in 1.

前記問題点に鑑み、本発明は、ドアミラー用サイドターンランプ全体の製造コストを抑制しつつ、ＬＥＤ光源からの光の利用効率を向上させることができるドアミラー用サイドターンランプを提供することを目的とする。 In view of the above problems, an object of the present invention is to provide a side turn lamp for a door mirror that can improve the use efficiency of light from an LED light source while suppressing the manufacturing cost of the entire side turn lamp for a door mirror.
