Abstract
【解決手段】 床、天井又は壁への組込み反射電灯特に階段反射電灯のような反射電灯(10)は、反射鏡(15)を持ち、この反射鏡は、楕円部分(17)又は放射線部分(23)にわたって延び、光出口面(KA−KF)の近くで弱く湾曲し、発光ダイオード(LED)(18)の近くで強く湾曲している。LED(18)は遮蔽体(A)の後にある。LED(18)、反射鏡縦方向に延びかつ遮蔽体(A)の自由端に設けられる直線縁(KA)、及び反射鏡縦方向に延びかつ反射面(16)の自由端にある直線縁(KF)が、共通な面にある、特にLED(18)の放射角(W)が、光出口面(KA−KF)の方へ放射する有効反射面の大きさを決定する。
