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 means. 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 means for solving reliability problems encountered in a cost reduction strategy for miniaturization of a prism and for using inexpensive plastic prism fixation members

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.
