    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: A projection type video display is provided with three LED light sources. 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. Lights in respective colors emitted from each LED light source are guided into a light incidence surface of a rod integrator by a cross dichroic mirror. The cross dichroic mirror is formed of a first cross dichroic mirror portion and a second dichroic mirror portion. The first cross dichroic mirror portion is divided into two portions, and the second cross dichroic mirror portion, too, is divided into two portions. The cross dichroic mirror has structure of a cross arrangement in which these four divided portions bring respective corner sides into close contact.

The second solid-state light source emits a light beam having a second directivity greater than the first directivity. A distance from the second arrangement surface to the second light-entering surface is longer than a distance from the first arrangement surface to the first light-entering surface.
