Projection display with direct light source cooling means

摘要

A projection display capable of preventing a reflector from damage and cooling a lamp at high efficiency. The projection display includes a light source which has a lamp and metallic reflector. The metallic reflector has an opening disposed above the light-emitting point of the lamp in the gravity direction. A duct has an end coupled to the opening and directs the air induced by a fan through the opening into the metallic reflector. The air then circulates within the metallic reflector to cool the light-emitting point of the lamp, and subsequently is released out of the metallic reflector through through-holes formed with a front glass and a flange of the metallic reflector.
