Abstract:
An apparatus (10) having a switchable display/mirror (11) and a display driver (12). In one mode of operation the switchable display/mirror provides a visual display to a viewer (using, for example, an emissive array). In another mode of operation the switchable display/mirror provides a mirror-like reflection. In a preferred embodiment, the switchable display/mirror includes a transparent organic light emitting diode array (31) that operates in conjunction with a reflective electrode (32) and a switchable circular polarizer (23). In one embodiment the switchable circular polarizer (23) can be comprised of a switchable linear polarizer (34) and a quarter waveplate (36).

A self-luminous image display apparatus of the present invention includes an output section for displaying an image, a reflection section provided on a rear side of the output section with a reflective surface thereof facing the output section, and a light-emitting section provided on a rear side of the output section. The output section includes a linear polarization device provided so as to cover a display surface for transmitting only predetermined linearly-polarized light of ambient light, and a retardation film provided closer to the light-emitting section than the linear polarization device for turning the linearly-polarized light transmitted through the linear polarization device into circularly-polarized light. The linear polarization device has a degree of polarization greater than 70.0%.
Abstract:
An illumination tube. The illumination tube includes a transparent tube, a reflecting layer, a phosphor and a plurality of electrodes. The transparent tube has a wall. The reflecting layer has an opening and is formed on a part of the wall of the transparent tube. The phosphor is formed in the transparent tube and covers the reflecting layer. The electrodes are disposed in the transparent tube. When the phosphor emits light by discharging the electrodes, the light is guided to the opening by the reflecting layer and transmitted via the opening.

Abstract:
The invention provides a colored filter, capable of emitting stable and bluish white light without causing a pigment to peel off even after use for many hours, and of being easily mounted in a xenon lamp or a halogen lamp, and a method of manufacturing the same. The colored filter for use in the xenon lamp or the halogen lamp is fabricated by dropping a coloring composition composed of only a pigment and a flux in the interior of a transparent cylindrical body while rotating the transparent cylindrical body around the axis thereof, uniformly coating the interior surface of the transparent cylindrical body with the coloring composition, and drying a uniform film of the coloring composition as formed before baking by heating
Abstract:
A discharge lamp includes means for containing a light emitting fill, the fill being capable of absorbing light at one wavelength and re-emitting the light at a different wavelength, the light emitted from the fill having a first spectral power distribution in the absence of reflection of light back into the fill; means for exciting the fill to cause the fill to emit light; and means for reflecting some of the light emitted by the fill back into the fill while allowing some light to exit, the exiting light having a second spectral power distribution with proportionately more light in the visible region as compared to the first spectral power distribution, wherein the light re-emitted by the fill is shifted in wavelength with respect to the absorbed light and the magnitude of the shift is in relation to an effective optical path length. Another discharge lamp includes an envelope; a fill which emits light when excited disposed in the envelope; a source of excitation power coupled to the fill to excite the fill and cause the fill to emit light; and a reflective ceramic structure disposed around the envelope and defining an light emitting opening, wherein the structure comprises a sintered body built up directly on the envelope and made from a combination of alumina and silica.

Abstract:
A refurbished picture projection unit lamp assembly comprising a housing for mounting within a projection unit and a lamp assembly. The assembly has a parabolic reflector with an inner reflective surface and a centrally located receiving aperture. A ceramic reflector base that is connected to an outer surface of the reflector has a mounting aperture aligned with the receiving aperture. An operable lamp is mounted within the mounting aperture leaving a gap between the lamp and the mounting aperture. At least one previously applied layer of ceramic cement partially fills the gap between the mounting aperture and the lamp. At least one newly applied layer of ceramic cement is applied adjacent the previously applied layer and the lamp filling the gap between the lamp and the mounting aperture holding and centering the lamp horizontally and vertically within the receiving aperture. The lamp has a spliced lead to complete the assembly.
