A projector (1) includes a light source lamp (41), a cooling device (6) adapted to feed a cooling fluid to the light source lamp (41) to thereby cool the light source lamp (41), 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 (41), and a cooling control section (76) adapted to control the cooling device (6), and the cooling control section (76) controls the cooling device (6) so that the cooling fluid at a flow rate lower than a set flow rate set in accordance with the second electric power value is fed to the light source lamp (41) during a predetermined period after the lamp electric power is switched from the first electric power value to the second electric power value. |
