<P>PROBLEM TO BE SOLVED: To provide an illumination fixture in which constitution for radiating the heat in a space part between the fixture main body and the shade to outside can be realized easily, and furthermore in which thinning can be realized. <P>SOLUTION: Since a heat radiation filter 40 composed of a porous resin is formed at least on the fixture main body 11 side in the shade 29, rising of temperatures of the air in a space part 32 formed by a reflecting plate 16 and the shade 29 of the fixture main body 11 can be suppressed, and reduction of the light emission efficiency of a circular fluorescent lamp 1 or failures or short life or the like of the electronic parts or the like of the lighting device 25 can be prevented. Furthermore, dimensions of the bottom part 31 of the shade 29 and the fixture main body 11 can be made smaller, so that thinning of the illumination fixture 10 as a whole can be carried out. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
