LAMP UNIT AND DISPLAY DEVICE OF PROJECTOR SYSTEM

摘要

A lamp unit of a projector system and a display device using the same, includes a lamp; a reflector for reflecting a light generated from the lamp; and a cover glass mounted at an opening of the reflector, and the cover glass having a blocking device for obstructing a light incident from an optical system, disposed in front of the light with respect to a light projecting direction, to the reflector. Accordingly, a light irradiated to the lamp, which increases the temperature of an electrode welding part of the lamp, can be blocked, thereby improving a lifespan of the lamp.
