PROBLEM TO BE SOLVED: To achieve miniaturization and improvement in uniformity of a light emitting surface.SOLUTION: In an optical block 23, a peripheral edge part is formed thick over the whole periphery, and a hook-shaped holding groove 233 is provided on a rear surface (surface being in contact with a reflection sheet 22) of this thick part. Then, an electric wire 26 is stored and held in the holding groove 233. Thus, as the electric wire 26 is held by the holding groove 233 provided in the optical block 23, space for wiring becomes unnecessary between LED modules 2 mounted on a mounting plate 30 of a reflector 3, and miniaturization becomes easier than a conventional example described in a patent literature 1. Furthermore, by making space between the LED modules 2 adjacent to each other narrow, improvement in uniformity of a light emitting surface can be achieved. |
