摘要： An image projecting apparatus including a light source emits a plurality of monochromatic rays of light with different wavelengths. A condenser lens concentrates the plurality of monochromatic rays. A first color separating unit rotates and selectively causes the plurality of monochromatic rays to be reflected therefrom or passed therethrough. A second color separating unit selectively causes the plurality of monochromatic rays that are passed through the first color separating unit to be reflected therefrom or passed therethrough. A square beam generating unit is inputted with the plurality of monochromatic rays reflected from the first and the second color separating units and transforms the monochromatic rays as inputted into square beams. A panel unit is inputted with the square beams of the monochromatic rays and forms a plurality of monochromatic images corresponding to the monochromatic rays.

摘要： An image projection system improves the brightness and/or color balance of a projected image. The system includes an auxiliary light source from which compensating light co-propagates with polychromatic light emitted by a primary light source along a primary light path. The compensating light has an emission energy content that minimizes an emission energy imbalance introduced by the primary light source. In a first preferred embodiment, the auxiliary light source is affixed at a location near the entrance end of a light tunnel such that the compensating light coincides with the primary light path before first reflection occurs. In a second preferred embodiment, the auxiliary light source is coupled to a light reflector adjacent to the primary light source and thereby allows the compensating light to propagate through the image projection system with the same efficiency as that of the light generated by the primary light source.

摘要： In order to prevent dust from sticking to the LCD panel, to prevent the LCD panel from being heated and to suitably adjust the position of the LCD panel, a duct is provided between cooling means for a light source and cooling means for a LCD panel to send cooling air from the LCD panel side to the light source side. Therefore, a light incidence/reflection plane of the LCD panel is disposed in an almost hermetically closed space and an optical path from an integrator lens to the LCD panel is formed in the almost hermetically closed space.

摘要： A projection display system includes: two light sources (102, 105); a condenser (103, 106) for condensing the light from the light sources; a time-division color separating optical system (108) for temporally switching the incident light into a first, second, or third color of light to be emitted; a light valve (118) capable of modulating the incident light individually for each pixel; a lighting optical system (111, 112, 114) for directing the light from the time-division color separating optical system onto the light valve, and a projection optical system (123) for magnifying and projecting a pixel on the light valve. The light from the two light sources (102, 105) is condensed on the time-division color separating optical system or its vicinity by the condenser (103, 106), and then superimposed. This can provide a projection display system that performs time-division driving and can achieve high-brightness projection images without increasing the size and cost of a system.

摘要： To increase the usage efficiency of the light of optical elements used in a projection display device, a polarizing conversion unit is provided. This polarizing conversion unit consists of a unit frame, two polarizing conversion element arrays, a light-shielding plate, a lens array, and clips. From the side of one open surface of the unit frame, the two polarizing conversion element arrays are inserted, and the light-shielding plate and the lens array are inserted from the side of the other open surface in this order. These optical elements are clamped by four clips from the two directions of up and down in a state of being stored in the unit frame. Since the clips are formed of an elastic body, the clips can be easily attached and detached, and the respective parts of the polarizing conversion unit can also be easily attached and detached to and from the unit frame. In addition, these optical elements may be sequentially inserted from the side of one open surface.
