<P>PROBLEM TO BE SOLVED: To solve such a problem that, in a lighting device in which a light source having directivity like an LED is used, uniform planar light emission cannot be attained due to existence of glare by directivity of the light source. <P>SOLUTION: In the lighting device having a plurality of substrates mounted with a plurality of light sources having directivity arranged on a plane side by side, the light sources and/or the substrates are located so that the light may be emitted uniformly in a plane where the substrate are arranged. <P>COPYRIGHT: (C)2012,JPO&INPIT |
