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： The invention enables efficient cooling of: a light source providing source light; an optical system adapted to split the source light received from the light source into three primary colors R, G, and B; and a power supply unit for supplying electric power to various electric components installed in a casing of a projector apparatus. To do so, a first fan is arranged between the light source and the power supply unit such that its air inspiration face is directed to the power supply unit and its air expiration face is directed to the light source. Further, a second fan, adapted to inspire air from within the projector apparatus, is provided in the central area of the projector apparatus. On the air expiration side of the second fan is a cooling duct for cooling the light source and optical system. In addition, a third fan for cooling a G-LCP unit and an R-LCP unit of the image synthesizing device and a fourth fan for cooling a B-LCP and an R-LCP unit of the image synthesizing device are provided in such a way that the streams of air expired from said third and fourth fans intersect each other. The invention allows operation of a projector apparatus with a fewer fans, yet achieves suppression of exhaust air temperature and noise, and cost reduction as well.

摘要： In a projection image display apparatus, a noise removal filter portion 15 is separated from a power source unit body 14. The separated noise removal filter portion 15 is provided in the vicinity of a side wall of a housing on which a power source inlet is provided, and of the power source unit body 14, respectively. Specifically, the power source unit body 14 is provided along a side wall of a front face of the horizontally-long housing of the projection image display apparatus and the noise removal filter portion 15 is provided in a position opposed to the power source unit body 14 in a side wall of the back face. As a result, even when a light source lamp has a higher output, the projection image display apparatus can achieve reduced noise by an improved cooling capability and reduced cost enabled by an efficient Electro Magnetic Compatibility (EMC) measure and the like.
