摘要： A projection type display apparatus includes a plurality of light sources 7a-7d, a display device unit 5, a light-combining unit 3 that combines output light from the plural light sources, a condensing unit 4 that propagates output light from the light-combining unit to the display device unit, and a projecting unit 6 that projects an image by the use of output light from the display device unit. In the projection type display apparatus, cooling units having fans 21a-21d are disposed respectively on the plural light sources, and a controlling unit 31 is provided to control the cooling units. Information regarding the lighting state of the plural light sources is inputted into the controlling unit, and the controlling unit controls a rotation rate of the fans of the cooling units with reference to the information. Concerning a case of temperature management of a plurality of light sources used, an accurate and reliable control is performed; problems such as whitening of the light sources, degradation of life property, blacking, brightness degradation and the like are suppressed, thereby high quality and high reliability are obtained.
