摘要： A projector is provided with a lamp including an arc tube, which generates light, and a reflector. The reflector includes an inner surface that reflects light from the arc tube and an opposite outer surface. The arc tube and the inner surface define an inner portion of the lamp. At least the outer surface defines an outer portion of the lamp. A housing accommodates the lamp and includes an air inlet through which air is drawn in from outside the housing. An air mixing structure mixes a cooling current that has cooled the inner portion of the lamp with the air drawn into the housing through the air inlet. A cooling current guide structure guides the cooling current mixed with the air mixing structure to the outer portion of the lamp.

摘要： A video projector including a light source used to display an image, an optical component that differs from the light source, a power supply unit that supplies power, and a centrifugal fan including a rotation shaft and a blade that rotates about the rotation shaft. The centrifugal fan is a double intake fan that draws in gas from first and second axial directions, which are parallel to the rotation shaft, by rotating the blade and sends the gas outward in a radial direction from the rotation shaft. The centrifugal fan sends gas that has cooled the optical component and the power supply unit to the light source.

摘要： A projector apparatus equipped with a metal plate structure serving as a light shield against a light source and as a heat radiator is provided. The metal plate structure is arranged over the light source to hide the light source. The metal plate structure extends farther to a cooling fan and connects to the upper end of the air expiration face of the fan. The metal plate structure thus serves as the top plate of the baffle section of the exhaust duct of the fan for leading the air expired from the fan. The metal plate structure also serves as a shield plate, which can be connected to a grounded metal piece.

摘要： A duct was configured such that an incident side and an outgoing side of each of liquid crystal panels 34r, 34g, and 34b are formed with discharge ports r1 and r2, g1 and g2, and b1 and b2 to discharge the air from fans 41 to 43 through ducts 411 to 431, and at the same time, a PBS 28 for aligning the polarizing direction of the light from a light source lamp is formed with a discharge port p1 to discharge the air from the fan 43 through the duct 432, and an incident side discharge port b1 and an outgoing side discharge port b2 of the liquid crystal panel 34b corresponding to the blue light are formed with the ducts so as to discharge the air from the fans 43 and 41 which are different from each other. As a result, even when an amount of light per unit area of high luminance is increased, the liquid crystal panels and the polarizing plates and the PBS can be effectively cooled by three sets of the fans.

摘要： A projection type video display apparatus having a projection lens opening (3) formed in the front end (1a) of the apparatus and a lend adjustment opening (5) formed in one end adjacent the front end, both openings protected against dust and external mechanical shocks. The projection type video display apparatus is adapted to project an image that is generated by modulating light emitted from a light source based on video signals, through a projection lens unit (2) exposed in the projection lens opening (3). The apparatus comprises lens adjustment members (e.g. adjustment dial 4) for zooming and/or focusing the projection lens unit (2), and a cover mechanism (slide cover 7) for opening and closing the projection lens opening (3) and lend adjustment opening (5).

摘要： The projector apparatus of the invention constructs colored imaging light by splitting a beam of light received from a light source into beams of three primary colors and inputting the beams of three primary colors in an image synthesizing device via light adjusting device. The image synthesizing device includes a prism, a prism mount for fixing the prism, LCPs, and LCP holders integral with the prism mounts for fixing the LCPs. The prism mount has a central area and multiple peripheral areas, each area in contact with the prism. The invention provides effective solution for solving reliability problems encountered in a cost reduction strategy for miniaturization of a prism and for using inexpensive plastic prism fixation members.
