VEHICULAR LIGHTING FIXTURE

To make an emission part of a light guide body look luminous substantially uniformly even in the case where one of first and second light sources is lighted, in a vehicular lighting fixture which is constituted so that light from the first and second light sources having different light emitting colors from each other is made to enter the light guide body and emit.SOLUTION: In a light guide body 30, as a constitution of a reflection part 34 for reflecting the light from first and second light sources 22, 24 which has entered from an incident part 32, a plurality of first light distribution control surfaces 34A for reflecting the light from the first light source 22 toward a lighting fixture front surface direction and a plurality of second light distribution control surfaces 34B for reflecting the light from the second light source 24 toward the lighting fixture front surface are provided. Then, the plurality of first light distribution control surfaces 34A and the plurality of second light distribution control surfaces 34B are arranged alternately. Thereby, even in the case where one of the first and second light sources 22, 24 is lighted, an emission part 36 of the light guide body 30 looks brightly luminous substantially uniformly.SELECTED DRAWING: Figure 3 【課題】発光色が互いに異なる第１および第２光源からの光を導光体に入射させて出射させるように構成された車両用灯具において、第１および第２光源のいずれが点灯した場合にも導光体の出射部が略均一に光って見えるようにする。【解決手段】導光体３０において、入射部３２から入射した第１および第２光源２２、２４からの光を反射させる反射部３４の構成として、第１光源２２からの光を灯具正面方向へ向けて反射させるための複数の第１配光制御面３４Ａと第２光源２４からの光を灯具正面方向へ向けて反射させるための複数の第２配光制御面３４Ｂとを備えた構成とした上で、複数の第１配光制御面３４Ａと複数の第２配光制御面３４Ｂとが交互に配置された構成とする。これにより、第１および第２光源２２、２４のいずれが点灯した場合にも導光体３０の出射部３６が略均一に明るく光って見えるようにする。【選択図】図３
