<P>PROBLEM TO BE SOLVED: To provide a lighting system capable of illuminating a subject with a preferable light ray by hardly degrading illumination efficiency, and preventing ring-like light distribution from occurring. <P>SOLUTION: A light ray from a light source is efficiently entered in the center of an optical member incident surface without forming a granulated part, and a light ray diffused from the end of a light emission area of a white LED module is diffused and entered by making the granulated part of the optical member incident surface generally equivalent to the end of the light emission area of the white LED module, whereby a color can be improved and the ring-like light distribution can be improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
