<P>PROBLEM TO BE SOLVED: To provide a lighting fixture capable of suppressing temperature rise inside a fixture main body formed by surrounding a light source part. <P>SOLUTION: The lighting fixture includes a thermally conductive fixing plate retaining light source parts 15a, 15b, and a fixture main body 14 formed of diecast aluminum. The fixture main body 14 includes an opening 19 irradiating light from the light source parts 15a, 15b, as well as a support part 21 supporting the fixing plate 18, surrounding and housing the light source parts 15a, 15b and the fixing plate 18. With this, heat generated at the light source parts 15a, 15b travels through the fixing plate 18, through the support part 21 of the fixture main body 14 mounting the fixed plate 18, and further, from the support plate 21 through the outer surface of the fixture main body 14, and is radiated from the outer surface of the fixture main body 14. <P>COPYRIGHT: (C)2008,JPO&INPIT |
