description To improve lighting fixture efficiency when light from first and second light emitting elements which is reflected by first and second reflectors is caused to be incident through a projection lens, in a vehicular lighting fixture equipped with the projection lens.SOLUTION: Light from first and second light emitting elements 20A and 20B which is reflected by first and second reflectors 30A and 30B are irradiated toward a front side of a lighting fixture through a projection lens 40. A common substrate 22 on which the first and second light emitting elements 20A and 20B are mounted is disposed in an inclined state in which light emitting surfaces 20Aa and 20Ba are oriented obliquely upward toward the front side of the lighting fixture. The second reflector 30B is disposed between the first light emitting element 20A and the second light emitting element 20B disposed at a position separated to the front side of the lighting fixture. Therefore, reflection light from the first and second reflectors 30A and 30B and direct light from the first and second light emitting elements 20A and 20B are caused to be incident to the projection lens 40 in a properly balanced manner, thereby improving lighting fixture efficiency.SELECTED DRAWING: Figure 3 【課題】投影レンズを備えた車両用灯具において、第1および第2リフレクタで反射した第1および第2発光素子からの光を投影レンズを入射させる構成とした場合の灯具効率を高める。【解決手段】第1および第2リフレクタ30A、30Bで反射した第1および第2発光素子20A、20Bからの光を、投影レンズ40を介して灯具前方へ向けて照射する構成とする。その上で、第1および第2発光素子20A、20Bが搭載された共通の基板22を、発光面20Aa、20Baが灯具前方へ向けて斜め上向きとなるように傾斜した状態で配置する。また、第2リフレクタ30Bを、第1発光素子20Aとその灯具前方側に離れた位置に配置された第2発光素子20Bとの間に配置する。これにより、第1および第2リフレクタ30A、30Bからの反射光と第1および第2発光素子20A、20Bからの直射光とをバランス良く投影レンズ40に入射させ、灯具効率を高める。【選択図】図3
