<P>PROBLEM TO BE SOLVED: To provide a lighting fixture using LED elements in which an irradiation range is of an almost circular shape and illuminance is improved. <P>SOLUTION: The lighting fixture is composed of a lens 2 which has a larger diameter from one edge to the other edge and in which a concave 210 is formed on one edge 21 and a bottom 210a of the concave 210 is formed in a convex lens shape, and a light emitting part 1 composed of an LED element 12 and a polygonal phosphor 13 covering the LED element 12 and arranged opposed on the bottom 210 of the concave par 210. The lens 2 is provided with a mask 24 for shielding light or a diffusion part 26 for diffusing light at least either in a region including at least a center in the bottom 210a of the concave 210 or a region of a part including at least the center of the other edge 22. <P>COPYRIGHT: (C)2011,JPO&INPIT |
