    摘要： The invention provides a projector that is capable of efficiently cooling an outer case along with a light source device. The projector includes an outer case that accommodates a light source device and a cooling passage that is formed in the vicinity of the light source device to cool the outer case. Therefore, the inside of the outer case and the vicinity of the light source device are cooled by the cooling passage so as to cool the outer case efficiently. Also, since the cooling passage is arranged in the vicinity of the light source device, the light source device can also efficiently be cooled. As a result, a temperature rise in the light source device can be restrained so as to cool the outer case more efficiently.

    摘要： An optical device (44) has a holding frame (446) that holds a liquid crystal panel (441) as an optical modulator and has an opening (446C) at a part corresponding to an image formation area of the liquid crystal panel (441), and a panel fixing plate (447) disposed between the holding frame (446) and a cross dichroic prism (444). The panel fixing plate (447) is made of a component having a thermal expansion coefficient lying midway between the thermal expansion coefficients of the holding frame (446) and the cross dichroic prism (444). The liquid crystal panel (441) is fixed on a side of the cross dichroic prism (444) through the holding frame (446) and the panel fixing plate (447). Accordingly, a thermal stress generated on the boundaries between the panel fixing plate (447), and the holding frame (446) and the cross dichroic prism (444) are reduced, thereby preventing the position shift of the liquid crystal panel (441).

    摘要： A projector prevents deterioration in optical characteristics of liquid crystal panels caused by heat generated by polarizers, and sticking of dirt onto the light-outgoing surface of the liquid crystal panels. Polarizers are disposed adjacent to the light-outgoing surfaces of liquid crystal panels, while other polarizers are disposed adjacent to the light-incoming surfaces of the liquid crystal panels. The liquid crystal panels and the two polarizers disposed adjacent to the light-incoming and light-outgoing surface of their corresponding liquid crystal panels, are supported by dust protection members. The area between the light-incoming surface of each liquid crystal panel and its associated polarizer disposed adjacent to the light-incoming surface, and the area between the light-outgoing surface of each liquid crystal panel and its associated polarizer disposed adjacent to the light-outgoing surface thereof are cut off from the outside by the dust protection member associated thereto. By virtue of this structure, it is possible to prevent deterioration in the optical characteristics of each liquid crystal panel, and to prevent dirt from sticking onto the light-outgoing surface of each light valve. Therefore, a high quality image with excellent contrast can be projected.

    摘要： The invention provides a light source device which can positively arrange a light source lamp at a predetermined position on an optical axis. To this end, the invention provides an alignment reference surface on a reflector to which the light source lamp is attached. More specifically, a light source device of the invention comprises a light source lamp, and a reflector for reflecting light emitted from the light source lamp, the light source lamp being attached to the reflector, wherein an alignment reference surface for aligning and mounting the light source lamp is formed on the reflector. According to the invention, the light source device can be assembled by mounting the light source lamp apart from the alignment reference surface by a predetermined distance with respect to, for example, the X-axis, Y-axis, and Z-axis, respectively. That is, in mounting the light source lamp to the reflector, it is possible to assemble the light source device without fine adjustment of the mounting position of the light source lamp while the light source lamp is lit.

    摘要： A projection display device projector capable of improving cooling efficiency of the power unit includes a light source lamp unit, a projection lens unit, an exhaust fan provided near the light source lamp unit for ventilating an outer case, and a ventilating path provided inside the power unit. A suction fan is provided at the inlet of the ventilating path which is connected to the cooling air intake port through a duct cover to directly conduct fresh air into the ventilating path. Because the interior of the power unit is cooled by fresh air which is cooler than the air inside the outer case, cooling efficiency is enhanced.

    摘要： A projection display device that promotes size reduction thereof, and that allows an optical system including optical modulation devices to be equitably and efficiently cooled. The projection display device includes a head body having an optical modulation device, a color synthesizing optical system, and a projection lens mounted thereon, a fan disposed in the head body, and a fan frame mounted on a prism bearing face at a plurality of points so as to hold the fan. The fan frame has a face that faces the prism bearing face and is shaped substantially like a quadrangle in outline, and one of the two diagonal lines of the quadrangle extends along the plane orthogonal to the prism bearing face. This makes it possible to mount the fan frame close to the projection lens side, and to thereby promote size reduction.
