ABSTRACT:
A panel cooling system A has a pair of Sirocco fans51A,51B arranged at both sides of the radial direction of a projection lens46,a suction duct portion52A and an exhaust duct portion52B. The suction duct portion52A communicates a suction port of the undersurface of an armored case2with a suction side of each of the Sirocco fan51A,51B, and the exhaust duct portion52B communicates an exhaust side of each of the Sirocco fans51A,51B and color lights R, G, B of an optical part. Thereby, a cooling air is blown to the vicinity of each light incident position of the color lights R, G, B of the optical part for approximately the same air quantity, so that the cooling of the optical part is performed
