Abstract
【解決手段】車両用前照灯装置は、ランプボディと、スラント部214aを有する透光カバー214と、灯具ユニット10とを備える。半導体発光素子12は、照射軸Xが光軸O1と交わるようにして光源載置面14aに載置され、リフレクタ16は、反射面16aを有し、反射面16aの一端が半導体発光素子12よりも車両後方側に位置し、他端が光源搭載部14の車両前方側端部14bよりも車両前方側に突出し、反射面16aのうち車両前方側端部14bよりも車両前方側に突出した突出部16a3がスラント部214aと対向するように設けられ、反射面16aは、第1領域がロービーム用配光パターンの水平カットオフラインを形成し、第2領域がロービーム用配光パターンの斜めカットオフラインを形成し、第3領域がロービーム用配光パターンの拡散部を形成するように構成されている。
【選択図】図2
Description
図1は、実施形態に係る車両用前照灯装置の内部構造を説明する概略鉛直断面図である。図1に示すように、実施形態に係る車両用前照灯装置100は、車両前方側に開口部を有するランプボディ212と、ランプボディ212の開口部を覆うように取り付けられた透光カバー214とを備える。透光カバー214は、車両前後方向に傾斜したスラント部214aを有する。ランプボディ212と透光カバー214とにより形成される灯室216内には、灯具ユニット10と、灯具ユニット30とが収容されている。また、灯室216内には、灯具ユニット10および灯具ユニット30を支持するブラケット50が収容されている。
