PROBLEM TO BE SOLVED: To provide a lighting system capable of emitting light uniformly on a whole part and having a comparatively thin shape.SOLUTION: A lighting system has a frame member 5, a first LED board 15 as a first LED assembly to be installed on the frame member 5, a translucent outer periphery cover 3 for covering the first LED board 15, and a central cover 4 detachable from the outer periphery cover 3. The central cover 4 is formed of a translucent material, and a second LED board 19 as a second LED assembly is installed on an inner side of the central cover 4, and then, a first LED light source group 17 of the first LED board 15 and a second LED light source group 21 of the second LED board 19 can be simultaneously lighted. Since surface luminance of the outer periphery cover 3 by the light emitted from the first LED light source group 17 and surface luminance of the central cover 4 by the light emitted from the second LED light source group 21 are made nearly equal, appearance at use can be improved. |
