摘要： A light-source device comprising: a rod integrator having an injection end and an emitting end; a lens unit for collecting a luminous flux emitted from the emitting end; and, a diaphragm. The rod integrator forms a plurality of imaginary light-source points, each of which virtually emits the luminous flux toward the emitting end. The diaphragm is disposed in the vicinity of a plane on which the lens unit forms the images of the imaginary light-source points, and selectively blocks luminous flux emitted from each of the images of the imaginary light-source points.

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 prism (1) has a first inner surface (114A) and a second inner surface (122) in its interior. The first inner surface (114A) performs total reflection of all rays (20) entering from the exterior, and is disposed apart from a variable mirror element (3) disposed in the exterior, such that the reflected rays are irradiated to the variable mirror element (3). The second inner surface (122) is disposed in proximity to the variable mirror element (3), and totally reflects a bundle of OFF rays from the variable mirror element (3), while allowing a bundle of ON rays from the variable mirror element (3) to pass therethrough.

摘要： A projection display device comprises: a diaphragm for the illuminating system disposed in the vicinity of a focal point of the light collected by the concave mirror; a collimation lens for rendering parallel the light passing through the aperture of the first diaphragm; a scattering-type liquid crystal light valve for forming forming image on its displaying surface; a field lens for converging the light rendered parallel by the collimation lens; a projection lens having an entrance pupil disposed in the vicinity of a focal point of the light converged by the field lens; and a second diaphragm having an aperture and provided in the projection lens. An aperture varying section of the first diaphragm varies the aperture diameter of the diaphragm of the illuminating system, and the other aperture varying section varies the aperture diameter of the diaphragm of the projection lens, thereby varying the diameter of an entrance pupil.
