<P>PROBLEM TO BE SOLVED: To provide an illumination fixture capable of improving both startability and vibration resistance even while suppressing brightness from being darkened. <P>SOLUTION: In the illumination fixture 1, the fixture main body 5 includes an annular core 2 through which a lamp 200 formed by an electrodeless discharge lamp having a bulb 210 formed of a translucent material is penetrated, induction coils 3 installed at the core 2 in a form of using the direction intersecting with the penetrating direction to the core 2 of the lamp 200 as the winding axis direction, and a lighting device 4 that generates a high frequency electromagnetic field for lighting the lamp 200 by supplying high frequency power to the induction coils 3. On the fixture main body 5, lamp holders 6 are installed which hold the lamp 200 at a prescribed position against the fixture main body 5. The lamp holders 6 are respectively formed of a metal material, and have an arm 60 which holds the bulb 210 in a form of exposing a site on the side opposite side to the fixture main body side in the bulb 210. <P>COPYRIGHT: (C)2009,JPO&INPIT |
