<P>PROBLEM TO BE SOLVED: To provide a lighting fixture having a natural image that is thin, has high efficiency and uniform luminance entirely, and glitters. <P>SOLUTION: Since a reflector 4a in the inner periphery of the lighting fixture 1 is adjacent to an LED 3, all segments 5a in the inner periphery are planar, thus forming a regular octagon with eight-side segments 5a. Contrarily, for segments 5b in a reflector 4b in the outer periphery, the surface of a section A-A is a slightly concave curved surface. As a result, light intensity is attenuated inversely with the square of distance from a light source, but the reflection light of the reflector 4a where the distance from the light source LED 3 is small and an attenuation factor is small is not condensed by the planar reflector 4a and is reflected upward, and the reflection light of the reflector 4b where distance from the light source LED 3 is large and the attenuation factor is large is condensed by the reflector 4b of the concave curved surface and is reflected upward, thus realizing the lighting fixture having a natural image that glitters where the entire luminance of the lighting fixture 1 is uniform. <P>COPYRIGHT: (C)2008,JPO&INPIT |
