PROBLEM TO BE SOLVED: To obtain a lighting system, having uniform illumination and realizing a low profile and miniaturization. SOLUTION: The light source of a lighting system 1 is arranged in a direction crossing the T bar 2b of a ceiling surface part 2. Light, radiated from a fluorescent lamp, is reflected by a reflection mirror, or is directly incident from the side surface of a light leading member to be uniformalized by a controller to be radiated from a reflecting opening 7. Since the light source 15 and a lighting circuit 18 are arranged in a direction crossing by the light leading member, parts can be efficiently and dispersedly arranged to realize miniaturization. Since the lighting system 1 is made flush with the lower surface of a ceiling board 2b to be thinned, wiring in the ceiling, or a duct space can be easily ensured. Since the light source 15 is positioned in a direction crossing the T bar 2a, the bar 2b acts no obstacle in replacing the light source 15. |
