Abstract
【課題】 幻惑光の防止を図ると共に左右方向における所望の照射領域及び照射輝度を確保する。
【解決手段】 発光ダイオードが用いられた光源8と該光源から出射された光が入射され入射された光を所定の方向へ向けて出射する透光レンズ12とを設け、透光レンズに、光源に対峙して位置する中央部14と、該中央部の外周側に位置し入射された光を内部へ導く導光部15とを設け、中央部に、光源に対向し該光源から出射された光が入射する入射面16と、該入射面から入射された光が出射される第1の出射面17とを形成し、導光部に内部へ導かれた光を出射する第2の出射面15bを形成し、中央部の第1の出射面に、左右方向への出射角度が光軸Sを基準として25°乃至50°となるように光を制御する制御面を形成した。
