Abstract
Employment of LED's in various applications began in recent years and in the not-too-distant future they are expected to displace current lighting sources in the average household. Incorporating characteristics of low-profile/large surface area/uniformity not found in lighting sources up until now, we proposed "flat light source" technology. This time, we suggest the segmentalized reflector in a reticular pattern to improve of light intensity distribution for "flat light source". We got the result that the variation of light intensity distribution is not grater than 16% in effective area. We proved the effectiveness of that optical system.
