摘要： The invention enables efficient cooling of: a light source providing source light; an optical system adapted to split the source light received from the light source into three primary colors R, G, and B; and a power supply unit for supplying electric power to various electric components installed in a casing of a projector apparatus. To do so, a first fan is arranged between the light source and the power supply unit such that its air inspiration face is directed to the power supply unit and its air expiration face is directed to the light source. Further, a second fan, adapted to inspire air from within the projector apparatus, is provided in the central area of the projector apparatus. On the air expiration side of the second fan is a cooling duct for cooling the light source and optical system. In addition, a third fan for cooling a G-LCP unit and an R-LCP unit of the image synthesizing device and a fourth fan for cooling a B-LCP and an R-LCP unit of the image synthesizing device are provided in such a way that the streams of air expired from said third and fourth fans intersect each other. The invention allows operation of a projector apparatus with a fewer fans, yet achieves suppression of exhaust air temperature and noise, and cost reduction as well.
