ABSTRACT:
A projector includes a light source; a light modulating device that modulates the flux of light emitted from the light source on the basis of image information to form an optical image; a projection optical system that projects the formed optical image; and an exterior housing that accommodates the light source, the light modulating device, and the projection optical system. An opening that introduces air from the outside of the exterior housing into the inside thereof is formed in the exterior housing. An object to be cooled, a duct connecting the opening to the objects to be cooled, and a filter purifying the air introduced from the opening are provided inside the exterior housing. A cooling fan that sucks the air having been purified through the filter and sends the air to the object to be cooled are provided in the duct.
