    摘要： There are provided a write light valve for generating image-writing light by modulating write light, a driver for writing images into the write light valve based on image data, read light valves for each color for generating respective color image lights by modulating each received color illumination light, an imaging lens group for guiding the image-writing light emitted from the write light valve to the respective read light valves, a dichroic cube for combining together color image lights emitted from the respective read light valves, a projection lens for projecting each color image light combined together. The imaging lens group has a distortion aberration which reduces or cancels out a distortion aberration of the projection lens.

    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： A projection lens unit and a projection mirror unit are moved relative to an illumination optical system, between a first position where an image is projected in a shape that is longer along a direction of projection onto a projection plane and a second position where an image is projected in a shape that is longer along a direction perpendicular to the direction of projection onto the projection plane. When the projection lens unit and the projection mirror unit are located in the first position, a vertically long image is projected onto the projection plane (portrait display). In this state, when the projection lens unit and the projection mirror unit are moved to the second position, a horizontally long image is projected onto the projection plane (landscape display).

    摘要： A LED light source is formed of a plurality of LEDs (light-emitting diodes). Primary optical axes of respective LEDs are set to be perpendicular to the plane surface (LED arranging plane surface). A first LED light source emits a light in red, a second LED light source emits a light in green, and a third LED light source emits a light in blue. An optical member has a first dichroic mirror portion and a second dichroic mirror portion alternately arranged, and the mirror potions inclined and arranged so as to form a saw-tooth appearance. Both the first dichroic mirror portion and the second dichroic mirror portion are designed to transmit the light in blue, and reflect lights in other colors.
