摘要： This invention provides a projection display capable of preventing a reflector from damage and cooling a lamp at high efficiency. The projection display comprises a light source. The light source includes a lamp and metallic reflector. The metallic reflector has an opening disposed above the light-emitting point of the lamp in the gravity direction. The 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 induced into the metallic reflector then circulates within the metallic reflector to cool the light-emitting point of the lamp, and subsequently is released out the metallic reflector through through-holes formed with a front glass and a flange of the metallic reflector.

摘要： This invention provides a projection enabling replacement of its lamp with minimum components. The light source lamp section includes a high-pressure discharge lamp and a metal reflector to which the high-pressure discharge lamp is attached. A plurality of engaging portions are provided on an opening rim of the metal reflector, while engaged portions are provided in a lamp housing section of the body of the projection display. The engaged portions are engaged with the engaging portions. By engaging the plurality of engaging portions of the opening rim with the engaged portions of the lamp housing section, the light source lamp section is secured to the lamp housing section of the body.
