摘要： An improved backlighting apparatus comprising a slab waveguide that accepts light rays generated by a light source and transmits the light rays via total internal reflection. Attached on one face of the slab waveguide is an array of microprisms, with each microprism having an light input surface parallel to a light output surface and at least one sidewall tilted at an angle from the direction normal to the surface of the waveguide such that light rays escape from the slab waveguide, reflect off the tilted sidewall and emerge from the microprism as a light source substantially perpendicular to the light output surface. An array of microlenses may be positioned to accept the output of the microprisms so that the light exiting from the microlenses is substantially more perpendicular. The backlight apparatus is advantageously used as a backlighting means for flat panel electronic displays.

摘要： An illumination system has a light source and a wavelength conversion layer within a light-recycling envelope. The wavelength conversion layer is a solid phosphor layer. The light source is a light-emitting diode or a semiconductor laser. The light source will emit light of a first wavelength range that is transmitted through the wavelength conversion layer in order to convert a portion of the light of a first wavelength range into light of a second wavelength range. Light of both the first and second wavelength ranges will exit the light-recycling envelope through an aperture. The recycling of the light by the light-recycling envelope will enhance the output radiance and luminance of the light exiting the illumination system.

摘要： This invention is an illumination system that incorporates a light emitting diode and a partially reflecting optical element. The light emitting diode emits internally generated light having a first angular range and reflects incident light with high reflectivity. The partially reflecting optical element transmits a first portion of the internally generated light with a second angular range, smaller than the first angular range, and reflects a second portion of the internally generated light back to the light emitting diode, where the second portion is reflected by the light emitting diode. The partially reflecting optical element can be a pyramid, an array of pyramids, a first and second orthogonal arrays of prisms or a bandpass filter. Utilizing a partially reflecting optical element and light recycling can increase the effective brightness and the output efficiency of the illumination system.

The light emitting diode includes a reflecting layer that reflects both the incident light and the internally generated light.

摘要： A projection display system has at least one light-recycling illumination system, a color scroller and an imaging light modulator. The light-recycling illumination system includes a light source that is enclosed within a light-recycling envelope. The light source is a light-emitting diode that emits light, and a fraction of that light will exit the light-recycling envelope through an aperture. The light-recycling envelope recycles a portion of the light emitted by the light source back to the light source in order to enhance the luminance of the light exiting the aperture. The fraction of the light that exits the aperture is partially collimated and is directed to a color scrolling means. The color scroller scans the partially collimated light across the face of the imaging light modulator. The imaging light modulator spatially modulates the scrolled beam of light to form an image.

摘要： An optical illumination assembly comprising an array of optical microprisms and microlenses for redirecting light from a light source. Such displays are used in a wide variety of applications such as backlit flat panel displays requiring a directed light source which provides an efficient output of light. The illumination assembly has a light transmitter optically coupled to an input end of array of microprisms through an optional diffuser, and a microlens on the light output end of each microprism. The microprisms have a light input end optically coupled to the light transmitting means and a light output end spaced from the light input end. Two pairs of oppositely positioned sidewalls having one an edge defined by said light input end and another edge defined by said light output end are positioned for reflecting of transmitted light toward the light output end; When light from the light transmitting means enters each microprism through the light input end, the light is directed by said sidewalls through the microprisms to each light output end and then through the microlenses. Optionally a light diffuser is positioned between the light transmitter and the input end of the microprisms.

摘要： An improved backlight assembly comprising an array of apertures in close proximity to a light source, an array of tapered optical elements that have a light input surface area smaller than the light output surface area. Light rays pass through the apertures and are directed to the optical elements which transmit the light rays via internal reflection to provide a partially collimated light source. The light rays then pass through an array of microlenses that transmit the light rays via refraction and provide a substantially more collimated light source for the display elements of a display. The backlight assembly is advantageously used as a backlighting means for electro-optical displays, especially those designed for military and avionics applications.

摘要： An optical illumination system comprising a waveguide that accepts light generated by a diffuse light source and transmits the light via total internal reflection. Attached on one face of the waveguide is an array of microprisms, with each microprism having an light input surface parallel to a light output surface and at least two sidewalls tilted at an angle from the direction normal to the surface of the waveguide such that light escapes from the waveguide, reflects off the tilted sidewalls and emerges from the microprism as a spatially directed light source. An array of microlenses may be positioned to accept the output of the microprisms so that the light exiting from the microlenses is a substantially collimated light source. The optical illumination system is advantageous for any application that requires a non diffuse or substantially collimated that is both energy efficient and contained in a low profile assembly.

摘要： An integrated barrier or partition (e.g. suspended ceiling, wall, etc.) containing lightweight solid state light sources wherein the light emitting surface of the light sources are the primary heat dissipating surfaces of the light sources. The light sources consisting of light emitting diodes (LED) in thermal contact to light transmitting thermally conductive elements and combined with a reflector element to form a light recycling cavity, provide both convective and radiative cooling from their light emitting surfaces, eliminating the need for external appended heat sinks. Seismically safe suspended ceilings contain integrated lighting where the lighting adds less than one gram per square foot to the structure. The lighting, integrated into but without penetrating the barrier (suspended ceiling, ceiling, wall, floor, etc.), is nonflammable and does not promote flame spread or smoke generation. The lighting is easily incorporated into ceiling tiles, sheetrock, grid elements, painted and/or wallpapered surfaces.
