In a liquid crystal projection apparatus having a plurality of lamps, and a plurality of cooling means for cooling the plurality of lamps individually, the lamp includes the following: a cup-shaped reflecting mirror 41 having an air discharge hole 41A, an insulator 50 having an air suction hole 50A, a front glass 42, a light emitting tube 40, and air passages (a) to (c) in the lamp for cooling the light emitting tube. The cooling means 12 sucks in hot air from the lamp, and exhausts the hot air toward the louver of the case. Thus, the lamps and the liquid crystal projection apparatus are cooled effectively. <IMAGE> |
