<P>PROBLEM TO BE SOLVED: To reduce the number of components constituting a light source device and also to enhance cooling performance for a light source. <P>SOLUTION: In the light source device 30, an inner wall member 50 constituted of a first inner wall 51, a second inner wall 52, and a third inner wall or the like is attached to the inside of a U-shaped housing 31. A front wall 40 integrated with the front part 42 of one side wall, the other side wall 60 and a back wall 70 are attached to the periphery of the housing 31. The light source 21 is attached to the inner surface 41c of the front wall 40, and the heat of the light source 21 is radiated through the front wall 40. A circulation fan 29 is attached to a rear part 34 forming the one side wall of the housing 31, and air flows from a duct part 43 at the front part 42 into the reflector 22 of the light source 21 by the actuation of the circulation fan 29, and the air whose temperature is high because of cooling a light emitting body 24 in the reflector 22 circulates along the periphery of the housing 31 and its heat is radiated from the other side wall 60 and the back wall 70. <P>COPYRIGHT: (C)2007,JPO&INPIT |
