Abstract
【課題】 部品点数の削減及び小型化を図った上で複数の所望の配光パターンを形成する。
【解決手段】 光を出射する光源10b、10b、・・・と、光源から出射された光を投影して照射する投影レンズ12とを設け、投影レンズの入射面16に第1の配光パターンP1を形成する第1の配光制御面17と第1の配光パターンより上方に位置される第2の配光パターンP2を形成する第2の配光制御面18とを形成した。これにより投影レンズに入射された光によって上下に位置される第1の配光パターンと第2の配光パターンが形成されるため、部品点数の削減及び小型化を図った上で複数の所望の配光パターンを形成することができる。
