摘要： A projection display device includes a light source, a reflector, and a fixing portion. The device further includes a first air supply portion and a second air supply portion; a first air drawing portion which separates the cooling air from the first air supply portion into streams of the cooling air to guide one of the streams into an interior of the reflector in a first direction and to guide the other of the streams to the fixing portion in a second direction; and a second air drawing portion which separates the cooling air from the second air supply portion into streams of the cooling air to guide one of the streams into the interior of the reflector in a third direction and to guide the other of the streams to the fixing portion in a fourth direction.

摘要： A projection display device includes a light source having a light emitting portion, a reflector which reflects light emitted from the light emitting portion, and a fixing portion which fixedly mounts the light emitting portion with respect to the reflector. The device further includes a first air supply portion and a second air supply portion which supply a cooling air; a first air drawing portion which separates the cooling air from the first air supply portion into streams of the cooling air to guide one of the streams of the cooling air into an interior of the reflector in a first direction and to guide the other of the streams of the cooling air to the fixing portion in a second direction; and a second air drawing portion which separates the cooling air from the second air supply portion into streams of the cooling air to guide one of the streams of the cooling air into the interior of the reflector in a third direction and to guide the other of the streams of the cooling air to the fixing portion in a fourth direction.

摘要： The projection display device includes an imager unit which modulates light from a light source, and a cooling device which cools the imager unit. In this arrangement, the imager unit includes a red imager which modulates light in a red wavelength band, a green imager which modulates light in a green wavelength band, and a blue imager which modulates light in a blue wavelength band. Further, the cooling device includes cooling fans which supply a cooling air to the imager unit. The cooling device is configured in such a manner that at least one of the cooling fans is provided for each of the red imager, the green imager, and the blue imager, and a plurality of the cooling fans is provided for at least the green imager.
