Abstract
【解決手段】半導体型光源6の光放射強度のうち最大光放射強度の放射方向V−Vが、投影レンズ7の光軸Z1−Z1に対して、後ろ側に傾斜している。この結果、半導体型光源6から放射される光L1のうち大部分の光であって相対強度が比較的強い光が反射面4で投影レンズ7の光軸Z1−Z1とほぼ平行にかつ投影レンズ7の光軸Z1−Z1に対して下側に反射される。このために、投影レンズ7から投影レンズ7の光軸Z1−Z1とほぼ平行な光L3が大量に出射されるので、投影レンズ7の光軸Z1−Z1とほぼ平行な光L3が大量に得られることとなり、比較的遠方の路面などを明るく照明する配光パターンP、PMを形成するのに適している。
