| 摘要 | A projector includes an optical part including a light source section that outputs light, a light modulator that modulates the light outputted from the light source section based on an image signal, a projection optical section that projects the modulated light from the light modulator, a first fan that cools the optical part, and a fan controller that controls the first fan, and the fan controller operates the first fan intermittently when the light source section outputs light of luminance lower than luminance corresponding to normal image display. | ||

| 主权项 | 1. A projector comprising: a light source section that outputs light; a light modulator that modulates the light outputted from the light source section based on an image signal; a projection optical section that projects the modulated light from the light modulator; an enclosure that accommodates the light source section, the light modulator. and the projection optical section: a first fan that exhausts air in the enclosure out of the enclosure; a second fan that cools the light source section: and a fan controller that controls the first fan and the second fan, wherein the fan controller stops the second fan and operates the first fan intermittently when the light source section outputs light of luminance lower than luminance corresponding to normal image display. | ||
