Description
投影レンズと、この投影レンズの後側焦点よりも後方側に配置された光源と、この光源を上方側から覆うように配置され、該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と、このリフレクタからの反射光の一部を上向きに反射させるための上向き反射面を有し、該上向き反射面の前端縁が上記後側焦点またはその近傍を通るようにして配置されたミラー部材と、を備えてなる車両用照明灯具において、
上記投影レンズの前面における略上半部が、稜線を介して複数の前面領域に分割されており、
上記投影レンズの後面における略上半部が、谷線を介して上記複数の前面領域と同数の複数の後面領域に分割されており、
これら各後面領域が、上記後側焦点の位置からの光を上記各前面領域から上記投影レンズの光軸と平行な方向へ出射させるように設定された表面形状で形成されている、ことを特徴とするものである。
