Abstract:
1. A projector comprising: a light source lamp adapted to emit light in accordance with a lamp electric power supplied to the light source lamp; a light modulation device adapted to modulate the light emitted from the light source lamp; a projection optical device adapted to project the light modulated; a cooling device adapted to feed a cooling fluid to the light source lamp to thereby cool the light source lamp; a lighting control section adapted to supply the light source lamp with the lamp electric power having either one of a first electric power value and a second electric power value higher than the first electric power value to thereby light the light source lamp; and a cooling control section that controls the cooling device to feed the cooling fluid to the light source lamp at a lower flow rate lower than a set flow rate set in accordance with the second electric power value during a predetermined period after the lamp electric power supplied to the light source lamp is switched from the first electric power value to the second electric power value, and controls the cooling device to feed the cooling fluid to the light source lamp at the set flow rate after the predetermined period elapses.
