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.

摘要： A projector which includes a first exhaust fan discharging exhaust air from a light source lamp to exterior and a second exhaust fan discharging exhaust air from parts other than the light source lamp are arranged to be adjacent to each other. An end of the exhaust fan facing the other exhaust fan is moved to the inner side and the one exhaust fan is inclined to discharge air in an exhaust direction toward a direction along which air is discharged from the other exhaust fan. There is provided a cooling fan that blows air to an interior air blow outlet communicating with the interior of the light source lamp and exterior air blow outlets communicating with an outer surface to cool the light source lamp. The exterior air blow outlets are deviated from the center of the outer surface of the light source lamp.

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： 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.
