<P>PROBLEM TO BE SOLVED: To provide a light source device capable of suppressing dispersion of temperature of each of a plurality of light emitting elements and warpage of a board by improving heat radiation performance of the plurality of light emitting elements, and suitable for reducing thickness. <P>SOLUTION: The light source device includes a light emitting device 3, a case body 11 and a projection window 23 facing to the device 3. The device 3 includes: boards 4 each having lock recessed grooves formed on both side edge parts thereof; a plurality of light emitting elements separately arranged on the surfaces of the boards; reflecting members 7 each having a lock part 7a hooked to the lock recessed groove and mounted to the board 4 and having a plurality of housing holes for individually housing the light emitting elements and a plurality of slits 7c for exposing the surfaces of the board between the housing holes formed thereon; and a translucent resin member filled by embedding the light emitting elements in the respective housing holes. By fixing the device 3 to the body 11 by tightly fitting the back surface with the boards 4 exposed therefrom to heat reception parts 13 provided for the case body 11, ventilation grooves 14 are formed oppositely to the back surface in the heat reception parts 13. A case cover 21 is mounted to the front surface of the case body 11 by forming a space S having the light emitting device 3 housed therein and communicating with the outside and the ventilation grooves 14 between the case body 11 and itself. <P>COPYRIGHT: (C)2007,JPO&INPIT |
