    摘要: A projection display apparatus includes an axial fan and a louver. The axial fan includes blades which are rotated to generate an airflow in an axial direction so that air is exhausted from a housing. The louver includes inclined plate portions which are inclined with respect to the axial direction, the inclined plate portions being arranged in a direction perpendicular to the axial direction at an airflow exit side of the axial fan, the louver being divided into a first area and a second area by a straight line which passes through an axial center of the blades, the inclined plate portions being inclined in different directions between the first area and the second area such that the inclined plate portions are inclined along the direction in which the blades are rotated.

    摘要: A light source lamp unit (10) includes a light source lamp (11), an ellipsoidal reflector (12) and a plate body (19). The plate body (19) is provided behind the reflector (12) with a gap kept therebetween, which has a shape corresponding to the profile of a reflecting portion (122) of the reflector (12). A cooling channel for passing a cooling air is formed between the plate body (19) and the reflector (12). The width of the cooling channel in a direction along an optical axis of the light source lamp (11) is minimized at a part near a neck portion (121) of the reflecting portion (122) and enlarged toward the peripheral edge of the reflecting portion (122) of the reflector (12).

    摘要: The light source device 10A has a light-emitting tube (11) (radial light source) and a reflector (12A). A cylindrical heat-conductive member (14A) is attached on an outer surface of a first sealing portion (114A) near a neck portion (121A) of a reflector (12A) in sealing portions (114) of the light-emitting tube (11). The heat-conductive member (14A) is attached along the outer surface of the first sealing portion (114A) with an end thereof being extended to a section near a light-emitting portion (113). A heat-radiation fin (15A) is attached on the other end of the heat-conductive member (14A).

    摘要: A projector includes a light source, an electro-optic device, a projection device, and a first seat and a second seat. The electro-optic device has plural light modulation devices that modulate lights emitted from the light source according to image information, and a light combining device, provided with plural light incident-side end faces to which the plural light modulation devices are attached, that combines respective lights modulated in the plural light modulation devices to form an optical image. The projection device includes at least one lens and a lens barrel accommodating and holding the lens, and projects the optical image formed in the electro-optic device in an enlarged form. The lens barrel includes a flange portion that expands outward in a base end portion in a projection direction. The first seat and the second seat are formed as separate bodies and are attached, respectively, to opposing two end faces of the light combining device that are orthogonal to the plural light incident-side end faces. The electro-optic device and the projection device are combined into one unit, the first seat and the second seat being connected to the flange portion.
