<P>PROBLEM TO BE SOLVED: To provide an illumination fixture which achieves thinning of the whole thickness, prevents fire from spreading from lighting circuit components or the like to a remote control light receiving circuit case or the like, and improves reception accuracy of control signals from a remote control device. <P>SOLUTION: The illumination fixture includes: fluorescent lamps 4, 4 deployed at a fixture body 2; a lighting device 6 formed by mounting, on the same circuit substrate, a remote control light receiving circuit portion having a light receiving sensor to receive light control signals from the remote control device, and a lighting circuit portion to receive the control signals from the remote control light receiving circuit portion in order to control lighting of the fluorescent lamps and light-emitting diodes; a resin-made remote control portion case 10 having a light guide cylinder 10c1 to receive the light control signals from the remote control device in order to guide light to the light receiving sensor and an opening to irradiate light emission of the light-emitting diodes to the outside, which covers the remote control light receiving circuit portion and the light-emitting diodes; and a lighting circuit portion case 9 made of non-flammable material, which covers the lighting circuit portion of the substrate and has a barrier rib 9c neighboring the remote control portion case. <P>COPYRIGHT: (C)2011,JPO&INPIT |
