    Abstract: An elongated LED lighting arrangement comprises an elongated light pipe with homogeneous optical material between first and second ends. In an exemplary embodiment, an LED provides blue light to the light pipe via a first dichroic mirror tuned to pass blue light. Down-converting means on sidewall of the light pipe, tuned to receive blue light, absorbs blue light from the LED and to emit lower-energy light outside of the light pipe at respectively higher wavelengths. Light-extracting means on the sidewall extract from the light pipe some blue light without changing the wavelengths of the foregoing light. Light from the down-converting means and the light-extracting means are combined to provide a composite color. The first dichroic mirror receives some light emitted by the down-converting means and reflects back into the light pipe more than 80 percent of the light received by the mirror.

    Abstract: An LED replacement-lamp design concept comprising tapered waveguides to provide uniform and broad light distribution is disclosed. Currently, most LED-based replacement lamps for tubular fluorescent lamps place discrete surface-mount LEDs directly on a cylindrical base, which produce wasteful, non-uniform and directional illumination unsuitable for large space and high-ceiling applications. An LED lamp design, proposed as a tubular lamp replacement, comprises of a plurality of discrete LEDs mounted on a common substrate, where all light from each LED is immediately guided and broadened through a tapered waveguide long enough to seamlessly terminate at the lamp's semi-circularly curved cover surface. Many such LED-waveguide assemblies can fill the entire curved cover with diffused and uniform light distribution, resulting in illumination over broad angular ranges.

  • Patent number: 8256918
    Abstract: A tubular luminaire efficiently utilizes the light of a line of high-brightness unlensed LEDs to reproduce the homogeneous appearance of a neon tube. The transparent tube has an annular cross-section suitable for cost-effective manufacturing by extrusion. The LEDs are mounted in a line on a circuit board that can be positioned either inside or outside the tube. Their light shines into a cylindrical groove, thereby entering within the material of the tube. Above the groove, the wall of the tube has a spiral shape that reflects the light laterally so that it stays within the annular tube for a considerable path length. Volume scattering by a low density of scattering inclusions causes the light to escape as a homogenous glow. Alternatively, mild surface scattering from the inside surface can be used.

  • Patent number: 5676452
    Abstract: An operating lamp has at least one main bulb 11 arranged at a desired position 13 and a replacement bulb 12 arranged at a waiting position 14 located close the desired position 13. The main bulb 11 and the replacement bulb 12 are displaceably mounted and controlled in such a way that when the main bulb 11 burns out it is moved away from the desired position 13 and the replacement bulb 12 is moved from the waiting position 14 to the desired position 13 and is held there. The main bulb 11 and the replacement bulb 12 are mounted on holders 15, 16 which are moveable independently of one another.

  • Patent number: 5570239
    Abstract: A directional light screen and method of making the same are provided. The directional screen includes a plurality of transparent carrier members having opposing sides, the carrier members being arranged in a side-by-side manner. Thin lamellae can be placed between the carrier members, or the carrier members can be spaced by an air gap. The screen is mountable proximal to a light source. The screen directs light from the source in a direction generally parallel to the sides and lamellae. The sides can be smooth, roughened or contoured. Also, the lamellae can desirably be tinted, absorbing or reflective. Furthermore, the directional screen can be shaped to fully or partially surround a light source.

  • Patent number: 5446629
    Abstract: This invention relates to a mounted emergency light fixture. The light fixture has a mount assembly and a front cover with a break plate which bends a light stick inserted into the fixture when the cover is pivoted from a closed position to an open position. The mount assembly has a restraining plate and a back side which maintain the light stick within the mount when the cover is pivoted to the open position. Hence, after the cover is opened the light sticks are illuminated and are held in the mount or may be removed to provide emergency lighting.

  • Patent number: 5301094
    Abstract: A lamp changer assembly for an overhead projector includes a reflector bracket and a lamp support bracket mounting two lamps. The reflector mounting bracket includes a slot and the lamp support bracket has attached thereto a slide which rides in the slot. Contact between the end points of the slot and the slide determines the position of the lamps relative to the reflector bracket and the reflector mounted thereon.

  • Patent number: 5178446
    Abstract: The lighting device has a central reflector (10), in which a first light source (11) is located in the operating position. A light guide (11) extends from the light source in the operating position and conducts light issuing directly from the light source and reflected light from the reflector (10) to vehicle light units. The first light source (11) is located in a supporting member (21) on which an additional second light source (22) is mounted. The supporting member (21) is movable relative to the reflector (10), so that on failure of the first light source located in the operating position the second light source (22) is moved in the operating position by a shifting device (26). The shifting device can have a control unit (36) and a sensor (37) connected to the control unit (36), which detects light issuing from the light source (11) in the operating position. On failure of the light source (11) the shifting device (26) is activated by the control unit (36).

  • Patent number: 5174648
    Abstract: An apparatus for supporting a primary lamp and a secondary lamp is disclosed. The apparatus comprises primary and secondary brackets, and primary and secondary sockets. The primary socket is affixed to the primary bracket, and receives the primary lamp, preferably a high intensity discharge lamp. The secondary bracket has a first end affixed to the primary bracket and a second end. The secondary socket is affixed to the secondary bracket, and receives the secondary lamp, preferably an incandescent lamp. The primary bracket defines a projected perimeter. The second end of the secondary bracket is normally biased to an operating position where the secondary lamp extends outside the projected perimeter of the primary bracket, but can be moved to a maintenance position where the secondary lamp is within the projected perimeter of the primary bracket. In operation, the secondary lamp is thus spaced apart from the primary lamp.

  • Patent number: 5032962
    Abstract: A mechanism for positioning one of a plurality of lamps, each carried by a lamp socket, at a desired focal point of an optical system is comprised of a first lamp socket positioned in an operative position such that a lamp carried by that socket will be at a desired focal point of the optical system. At least one other lamp socket is positioned in an inoperative position. A mechanism for enabling movement of the first lamp socket from the operative position to an inoperative position while simultaneously moving the other lamp socket from the inoperative position to the operative position is provided. The present invention enables a failed lamp to be replaced by a backup lamp in such a manner that no degradation or change in optical performance occurs.
