Description
投影レンズとこの投影レンズの後方に配置された光源とを備え、上記光源からの光を上記投影レンズを介して前方へ照射することにより所定の配光パターンを形成するように構成された車両用灯具において、
上記投影レンズが、灯具正面視において細長く延びる外形形状を有しており、
この投影レンズの周囲に、上記光源からの光を前方へ向けて透過制御する付加レンズが配置されており、
上記光源からの光を上記投影レンズへ向けて反射させるリフレクタを備えており、
上記光源からの光を2回反射させた後に上記付加レンズに入射させるための第1および第2付加リフレクタを備えており、
上記第1付加リフレクタが、上記光源から上記投影レンズへ向かう直射光の一部を遮光する位置に配置されている、ことを特徴とするものである。
第1付加リフレクタ34は、リフレクタ16よりも前方側に配置されており、発光素子14から前方へ向かう直射光を斜め後方へ向けて反射させるように構成されている。
