    摘要: An illuminating device comprises a first light source in which LED chips are arranged in an array shape and a second light source in which LED chips are arranged in an array shape. The two light sources of each illuminating device are arranged such that the main light-emission optical axes of the light sources are perpendicular to each other. Moreover, a time-division switching mirror is provided at a crossing position between the main light-emission optical axes. The first light source and the second light source alternately emit pulses of light. The pulsed emission is a method of supplying a large amount of electric currents to the LED chips in a short time period, and a light-emitting amount increases compared to a steady-state emission of the LED chips. The time-division switching mirror becomes a transmitting state when the first light source is lighted, and becomes a reflecting state when the second light source is lighted.

    摘要: A projection type video display is provided with three illuminating devices R, G, B. The illuminating device R emits light in red, the illuminating device G emits light in green, and the illuminating device B emits light in blue. The lights emitted from the respective illuminating devices are guided onto transparent liquid crystal display panels R, G, B by convex lenses. Each illuminating device is formed of a light source, a light guide, a condenser lens, and an integrator lens. The light source is formed of having one or a plurality of LED chips aligned on a plain surface. The LED chips have photonic crystal structure, and a light-emission direction approximately vertical to a light-emitting surface, thus high in directionality.

    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: 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).
