PROBLEM TO BE SOLVED: To provide a luminaire capable of performing desired light distribution control while suppressing glare, by combining a light permeable mirror and a reflecting mirror.SOLUTION: A luminaire includes: a front cover 30 arranged in front of a light source 20; and a reflecting mirror 40 arranged opposing to the front cover 30 from behind the light source 20. The front cover 30 is formed by a light permeable mirror which divides the light emitted from the light source 20 and the light reflected by the reflecting mirror 40 into the light for radiating the outside part by transmitting to the outside and the light reaching the reflecting mirror 40 by reflecting to the inside, at a predetermined ratio. The reflecting mirror 40 is formed in such a manner that, by receiving the light reflected to the inside by the front cover 30, it repeatedly reflects it toward the front cover 30 at a predetermined angle.SELECTED DRAWING: Figure 1
