    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.

    摘要: Modulated light (image light) which has been modulated by passing through a liquid crystal display panel passes through an apical angle variable prism (so-called, a vari-angle prism) and then is enlarged and projected by a projection lens. The apical angle variable prism is configured to change the prism apical angle with, for example, an electromagnetic actuator. The microcomputer calculates a projection optical axis correction value based on hand shake detection signals from a sensor and controls the aforementioned actuator based on the correction value. With this control, shakes of projected images due to hand shakes are prevented.

    摘要: The auxiliary light source has LED chips respectively emitting red lights arranged therein in an array shape, and has lens cells for parallelizing light arranged therein on the light exit side of the LED chips, for example. The LED chip is arranged in correspondence with each of lenses composing a pair of fly's eye lenses, and the pair of lenses introduces the light emitted from the LED chip into the whole surfaces of liquid crystal panels. A mixing mirror transmits white light emitted from a main light source and reflects light emitted from the auxiliary light source, and mixes the white light and the auxiliary light respectively emitted from both the light sources and introduces the mixed lights into the pair of fly's eye lenses.
