<P>PROBLEM TO BE SOLVED: To provide a lighting fixture using an LED element with an irradiation range of an almost circular shape and having improved illuminance. <P>SOLUTION: The lighting fixture includes a base substrate 1, a light emitter 2 composed of an LED element 21 arranged on the base substrate 1 and a phosphor 22 of a polygonal shape covering the LED element 21, a dome member 3 which is formed of a translucent resin in a dome shape and covers the light emitter 2 and diffuses light irradiated from the light emitter 2, and a lens 4 performing light distribution control of the light from the light emitter 2 irradiated through the dome member 3. The light emitters 2 are arranged in plurality in an almost concentric circle on the base substrate 1, and at least one light emitter 2 has an arrangement direction different from other light emitters 2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
