Abstract:
A projector comprising:a light source; a projection optical system that enlarges and projects a light beam irradiated by the light source after being modulated in accordance with image information, where an optical path from the light source to the projection optical system is arranged approximately in planarly-viewed L-shape; a light source cooling axial-flow fan provided adjacent to the light source with a suction surface thereof extending along the optical axis of the light beam irradiated by the light source; an exterior case that accommodates the light source and the projection optical system, the exterior case having an exhaust hole that discharges an air inside the exterior case toward outside; and a duct that connects a discharge portion of the light source cooling axial-flow fan with the exhaust hole of the exterior case, wherein the light source cooling axial-flow fan exhausts a cooling air in the projecting direction of the projection optical system.
