Abstract
【解決手段】 左右方向に並んで配置された複数の半導体発光素子15と半導体発光素子から出射された光を反射し半導体発光素子の下側に配置された下側リフレクター18とを有する光源体13と、半導体発光素子から出射された光を投影して照射する投影レンズ32とを備え、遠距離の領域を照射するハイビームの配光パターンP1における上部のパターンH2が下側リフレクターで反射され投影レンズから照射される光によって形成され、半導体発光素子から出射され下側リフレクターに入射される光の入射状態が制御されてハイビームの配光パターンにおける上部のパターンの形成状態が変化されるようにした。従って、ハイビームの配光パターンにおいては歩行者における上部側に光が照射されないように制御されるため、運転者の視認性の向上を確保した上で、歩行者に対する眩惑光の発生を防止することができる。
