    摘要: A rear projection display, not requiring a dichroic prism, and capable of rendering a generation system of each image light in color independent of the other generation systems so as to optimally construct and improve easiness of assembly of, and so on, each generation system, is provided. Each unit for projecting image-light is formed of an LED array, a rod integrator, a liquid crystal display panel, and a projection lens. A projection optical axis of the projection lens of each unit for projecting image-light is parallel each other. A unit for projecting image light in red is provided with an LED array for emitting light of a wavelength band in red, a unit for projecting image light in green is provided with an LED array for emitting light of a wavelength band in green, and a unit for projecting image light in blue is provided with an LED array for emitting light of a wavelength band in blue. Each image light in color obtained as a result of passing through the liquid crystal display panel is projected by the projection lens, and displayed on a screen. As a result, each image light in color is superposed on the screen, and an image in full color is displayed.

    摘要: An illuminating device includes a discharge lamp, a condenser lens, an integrator lens, a polarization conversion system, an electromagnetic wave shielding plate, and an electromagnetic wave shielding wall. A light given out from each lens in the light-incident-side fly's eye lens becomes two light fluxes via respective polarizing beam splitters and the two light fluxes pass through two lenses in the light-exit-side fly's eye lens. The electromagnetic shielding plate has an aperture on an optical axis of each lens in the light-exit-side fly's eye lens. The electromagnetic wave shielding plate is grounded through the electromagnetic wave shielding wall.

    摘要: An ion wind generator (20) is arranged on one side of a light source (1). The ion wind generator (20) produces an air current by negatively ionizing air by corona discharges at a needle electrode (21), or negative side, and drawing the negatively-ionized air at a cylindrical electrode (22), or positive side. The air current blows toward the light source (1) and removes heat generated by the light source (1). An ultraviolet ray from the light source (1) is introduced to a vent of the ion wind generator (20) by a first dichroic mirror (4) and a ultraviolet ray reflection mirror (17). Though air exhausted from the vent includes ozone (o3) produced by corona discharges, the ozone is decomposed by the ultraviolet ray.

    摘要: An ion wind generator is arranged in the vicinity of a light source. The ion wind generator allows an air flow by negatively ionizing air by corona discharges using negative side needle electrodes, and drawing the negatively-ionized air using a ground side mesh electrode. High-temperature air surrounding the light source is drawn by the air flow and exhausted from an exhaust port at a rear side of a casing. An ozone decomposition catalyst filter is provided in the exhaust port. Ozone (O3) is generated by the corona discharges in the ion wind generator. However, the ozone is decomposed by passing through the ozone decomposition catalyst filter provided at the exhaust port.
