    摘要： A projector comprising liquid crystal display panels and a projection lens for projecting the modulated light to a screen. A back surface reflection mirror including a transparent plastic sheet and a reflecting film is arranged between the projection lens and the screen. The mirror is thin and light and may have optical anisotropy. In order to eliminate an uneven pattern appearing in the screen caused by optical isotropy of the mirror and the difference between the light distribution characteristics in the screen for P- and S-polarized light, the projection lens and the back surface reflection mirror are arranged in such a relationship that a wave normal vector of an arbitrary component of the light projected by the projection lens and made incident to the back surface reflection mirror is not parallel to the optical axis of the plastic sheet.

    摘要： A light source for use in a projection type liquid crystal display device. The light source includes an electrodeless light emitting member having a light emitting material sealed in a transparent tube to emit light upon the application of microwave electromagnetic energy. A concave mirror is arranged on the outside of the light emitting member, and the transparent tube is supported by a rotatable rod-like support member which extends through the concave mirror. Means in the form of a vane, a screw or a projection is arranged on the rod-like support member or on the light emitting member for stirring air, while the rod-like support member rotates, to cool the light emitting member.

    摘要： The projection type display apparatus has liquid crystal panels with polarizers, a light source, a power supply, and a ballast. A cooling device is arranged in the apparatus such that a first set of cooling fans blow cooling air to cool the liquid crystal panels and the polarizers, and a second set of cooling fans suck the cooling air passing through the liquid crystal panels and the polarizers and blow the cooling air to independently cool the light source, the power supply, and the ballast. Therefore, a projection type display apparatus with little light leakage and low noise can be realized. The invention also provides a cooling unit, for the light source, which includes a movable lamp house and a duct with a cooling fan.

    摘要： A lens array 22C has convex lenses 221 and 221C arranged in alternate and staggering manner to one another. In combination with a condenser lens 23, the convex lenses 221 form images of respective convex lenses 211 of a lens array 21 on a plane 24 to be illuminated in overlapping so that an illuminance distribution on the plane 24 is almost uniform, while the convex lenses 221C whose focal length is longer than that of the convex lenses 211 make on the plane 24 an illuminance distribution of a mountain-shape. Flat plate portions and concave lenses may be employed instead of the convex lenses 221C. A polarization conversion element comprises two elements and an element disposed therebetween with its longitudinal direction being perpendicular to the two element. The images of a light emitting part are included in band-shaped useful incident areas. A polarization conversion section comprises a middle part which is thin but has a larger divergent angle and side parts each has a smaller divergent angle and a simpler construction but is thicker with its size larger.

    摘要： A lighting unit including a light-reflecting reflector, a plurality of cold cathode tubes disposed inside the reflector and an optical waveguide connected with an open end of the reflector to guide the light emitted by the cold-cathode tubes. The reflector has a reflective surface that reflects the light having been emitted by the cold-cathode tubes in the direction nearly perpendicular to the wall of each tube, and only in a direction in which the light reflected does not re-enter the cold-cathode tubes. In another embodiment, the lighting unit may include a second optical waveguide disposed in the space between the cold-cathode tube and the reflector, wherein a space is formed between the cold-cathode tube and the second optical waveguide.
