<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an LED illumination substrate that can secure superb illumination characteristics at low cost. <P>SOLUTION: In manufacturing the LED illumination substrate structured by mounting a plurality of LED elements on a substrate, loading reference positions for loading light diffusion lenses are first detected targeting on the substrate with the plurality of LED elements mounted on element-mounting positions, and at loading of the lenses after application of adhesives on the substrate, each light diffusion lens is loaded on each LED element based on the loading reference position detected. With this, the light diffusion lens can be loaded at an appropriate position of the LED element, and superb illumination characteristics can be secured at low cost in manufacturing of the LED illumination substrate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
