PURPOSE:To provide a luminaire which can be applied to different distances of sides facing to each other in radiation apertures with flexibility, and for which attachment/detachment work can be performed easily. CONSTITUTION:A pair of reflection side plates 43, 43 are slidably installed to a lower surface of a reflection top plate 42 facing each other on both sides to be developed downward to form a reflection body 41. The reflection top plate dj42 is installed to a lower surface of an apparatus main body 21 by ornamental screws 55, and support parts 54, 54 formed at lower ends of the reflection side plates 43, 43 are mounted to mounting parts in a ceiling frame, so the reflection body 41 is installed. By thus installing the reflection side plates 43, 43 slidably to be applied to a distance between the mounting parts facing to each other, need of preparing plural sorts of reflection bodies is eliminated, but only one sort is required. Need of deforming the reflection body resiliently is eliminated, and attachment/detachment work can be performed easily. |
