Abstract
【解決手段】LED8の位置をほぼ焦点とする回転放物面を基調とする反射面9が8個に分割されており、この8個の反射面9が、LED8からの光のうち主に半値角以内の光Lを所定の方向に反射させて配光規格を満足させる4個の第1反射面11群と、LED8からの光のうち主に半値角以外の光L2を所定の方向に反射させて発光範囲を広げかつ発光範囲の形状を調整する4個の第2反射面12群と、からなり、第1反射面11群の回転放物面のF値が第2反射面12群の回転放物面のF値よりも小さい。この結果、反射面9の発光範囲をある程度大きくすることができ、しかも、反射面9の発光範囲の形状を円形以外に任意の形状に調整することができる。
