Projection type display apparatus

Abstract

A projection type display apparatus wherein heat generated from a plurality of heat sources in an outer housing can be exhausted efficiently and the weight of the outer housing can be balanced readily in the leftward and rightward direction. A projection lens is disposed at a central location of a front wall of the outer housing, and first and second exhaust mechanisms including first and second exhaust fans for exhausting heat generated by a light source section in the outer housing and a setting power supply circuit board and a light source section power supply circuit board which serve as a power supply section independently of each other, respectively, are disposed on the opposite left and right sides of the optical unit in the outer housing. First and second exhaust ports of the first and second exhaust mechanisms are disposed on the opposite left and right sides of the projection lens in the front wall of the outer housing. In order to prevent a schlieren of a projected light flux by hot wind from the exhaust ports, baffles are provided for guiding exhaust hot winds exhausted from the projection lens and the first and second exhaust ports so that they may not advance into the projected light flux.
