Claims (1)
- ロービーム用の複数の発光ダイオードと、該発光ダイオードからの照射光を車両前方に向けて反射させるリフレクタと、該リフレクタにより反射された反射光の一部を遮り対向車を照射しないようなロービーム用の配光パターンを形成するシェードと、前記発光ダイオードを配置する基板と、該基板の裏面に固着され前記発光ダイオードからの発散される熱を放熱するヒートシンクとを備えた車両のヘッドランプにおいて、
前記複数の発光ダイオードを前記基板上で車幅方向に分散して配置し、前記ヒートシンクを放熱用の板状部材から構成し、その前端部を折り曲げて端末に配光カットオフラインを有する前記シェードを形成し、前記基板と前記ヒートシンクと車両前方側が開口したドーム状の前記リフレクタの底部とがオーバーラップしたことを特徴とする車両のヘッドランプ。
