<P>PROBLEM TO BE SOLVED: To provide a light source device capable of restraining luminance unevenness illumination light caused by a reflecting member having an opening where a plurality of lenses and a fixing tool are prepared. <P>SOLUTION: The lens 3 corresponding to each light-emitting element 1 is arranged on one surface side of a circuit board 2 where a plurality of light-emitting elements 1 are mounted, a part of a plurality of fixing tools 8 for fixing the circuit board 2 on a support located at the other surface side are projected to one surface side of the circuit board 2, and the reflecting member 4 having the opening where each lens 3 and the fixing tool 8 are prepared. The plurality of lenses 3 are arranged in parallel on two directions crossing each other on one surface of the circuit board 2 at approximately even intervals, the plurality of fixing tools 8 are located between two adjacent trains among a plurality of trains of lenses 3 along one of two crossing directions at a zigzag state so as to mutually approach to the lenses 3 of each train, and the opening of the reflecting member 4 is an opening wherein an opening 43 where the fixing tool is prepared and an opening 41 where the lens 3 approached with the fixing tool is prepared are united each other. <P>COPYRIGHT: (C)2011,JPO&INPIT |
