摘要： In a light source apparatus for use with a projection type display, at least one light source is provided for emitting light. A reflector is provided correspondingly to the light source in order to gather the light emitted from the light source into a small area to form a converged luminous flux. A light guide has at least one light input section into which the luminous flux is coupled. The light input section is provided correspondingly to the light source. The light guide combines the luminous flux received through the light input sections into a single beam of luminous flux. The light-guide has at least one light output section from which said luminous flux is output. The light source apparatus may also include light-refracting element provided between the reflector and the light-guide. The light-refracting element receives the converged luminous flux from the reflector to refract the converged luminous flux so as to couple the converged luminous flux, as a uniform luminous flux, into the light-guide.

摘要： A projection type display apparatus includes a light source, color separator, half-wave plate, a plurality of light valves, color synthesizer, and projection lens. The light source emits a substantially parallel illumination flux. The color separator separates the light emitted from the light source into light of three colors including red, green, and blue. The light of the respective color passes through the corresponding half-wave plate which is placed in the light path of the light and causes the plane of vibration of the light to rotate through a predetermined angle. Then, the light of each color exiting the half-wave plate passe through the corresponding light valve, being modulated into a color image. The color synthesizer synthesizes the color images into a single full-color image and the projection lens enlarges and projects the single full-color image formed.

摘要： A light source device including a light emitting element emits a luminous flux, which is converged by a reflecting mirror. A conical light-refracting element receives the luminous flux converged by the reflecting mirror and changes the cone angle of the luminous flux. The luminous flux exiting the conical light-refracting element is diffused by a holographic diffuser and is then converged by at least one lens. The reflecting mirror may have an elliptic curvature or a parabolic curvature. The light source device is also used to form a projector for a projection type display apparatus. In the projector, the luminous flux emitted from the light source device may be separated by color separators into a plurality of colors of light. Then, each color of light is directed to the corresponding one of a plurality of light valves. Then, a color synthesizer synthesizes the colors of light emitted from the light valves into a composite image which in turn is projected onto a screen. A plurality of such projectors are used to construct a multiscreen projection type display system where each of the projectors projects a corresponding image. At least one reflecting mirror for bending a corresponding one of the images is included in the multiscreen projection type display system. The reflecting mirror projects the image onto a screen so that the images emitted from the plurality of projectors are combined into a composite image on the screen.
