<P>PROBLEM TO BE SOLVED: To provide a projector capable of efficiently cooling its inside by effectively dissipating the heat caused by the irradiation of luminous flux in a non-visible region which is transmitted through a reflector. <P>SOLUTION: The projector 1 includes: a non-visible light reflection member 82 disposed on the backward side in light emission of the reflector 12, and having a non-visible light reflection surface 821 to reflect non-visible light R3 transmitted through the reflector 12 out of the luminous flux emitted from a light source lamp 11, and condense it at a predetermined position; and a non-visible light absorbing member 83 disposed at a cooling feasible position and absorbing the non-visible light R3 reflected by the non-visible light reflection member 82. <P>COPYRIGHT: (C)2007,JPO&INPIT |
