PROBLEM TO BE SOLVED: To suppress degradation of a fitting bracket of such luminaire as fitted to the inner wall of a tunnel, even if a reflector is fitted to the luminaire body using a resin fitting bracket. SOLUTION: A reflector 3 and a light source lamp 4 are provided in a luminaire body 2. The luminaire is fixed with a resin fitting bracket at the part closer to a bottom surface side of it than to the end of the reflector 3. Since the resin fitting bracket is shielded from the heat or ultraviolet ray emitted from a light source lamp by an end plate of the reflector, it is immune to degradation under heat or ultraviolet ray, for improved reliability.
