20140328080 | ARC LAMP HAVING DUAL PARABOLOID RETROREFLECTOR - An illumination system comprises an arc lamp having a cathode and an anode which emit light from a hot spot. A dual paraboloid retroreflector comprising upper and lower halves intercept light emitted rearwardly from the arc lamp and reflects the intercepted light back towards the hot spot. The retroreflector is spaced from the hot spot at a distance such that light rays emitted from the hot spot which are incident on the upper or lower half are redirected to a corresponding surface of the other half and reflected back to the hot spot. The system may further include a main dual paraboloid reflector for redirecting output light from the arc lamp and retroreflector. Light emitted from the arc lamp is intercepted by a first half paraboloid reflector and collimated to be redirected toward to a corresponding surface of a second half paraboloid reflector member, so as to be reflected in a direction opposite to the arc lamp output. The system may include a pair of ellipsoid reflectors, one of which intercepts the arc lamp output and directs the light onto a corresponding surface of the other ellipsoid reflector, which change the output direction of the light to be parallel to the arc lamp output. | 11-06-2014 |
20140313459 | LIGHT BOX FOR BACKLIGHT OF AN LCD MONITOR - An LCD monitor comprises an LCD panel and a backlight for providing illumination to the LCD panel. The backlight includes a light box having a reflective bottom and sides and an open top for allowing light to flow outwardly toward the LCD panel. The light box includes a light source preferably comprising a plurality of LED elements for generating light either from said edge or from said bottom, or from both said bottom and said edge. The light box further preferably comprises a plurality of wave plates interspersed with the LED elements for intercepting light and changing the polarity of such intercepted light. Preferably, the backlight includes a polarizer for transmitting light from the light box of a first polarization towards the LCD panel and reflecting light of a second polarization back towards the light box. At least some of the reflected light of the second polarization passes through the wave plates, is converted to the first polarization, and is reflected back towards said polarizer. Thus, the wave plates act as secondary light sources and assist in producing a uniform light output. | 10-23-2014 |
20140252958 | WIRELESS CONTROLLED LIGHT SOURCES - A network comprises a plurality of modules, wherein each module comprises a communications circuit with an antenna for sending information signals to and receiving control signals from a remote base over a wifi connection. Each module includes either a lighting element or a security camera for providing images. Each module may further include sensors to provide information to the base concerning operating conditions. Preferably, each module is programmed to receive signals from other modules and to relay such signals to the remote base, and similarly route control signals from the remote base intended for a different module to the intended module. In one embodiment, the network is a lighting network in which each module includes a light source controlled by the remote base or by a control terminal connected to the remote base. | 09-11-2014 |
20140078730 | LAMP SYSTEM HAVING PARABOLIC REFLECTOR WITH TWO REFLECTIONS FOR RECYCLING LIGHT - A lamp system comprises a light source and a parabolic reflecting collar positioned around the light source and having an aperture through which a center axis extends. The aperture permits light rays emitted by the light source at low angles relative to the axis to be emitted from the parabolic reflecting collar, while light rays emitted by said light source at higher angles are reflected by the collar for recycling. The parabolic reflecting collar is positioned such that higher angle light rays are reflected twice, off opposing wall reflecting portions, back to their point of origin. Preferably the light source is an array of multiple LEDs having different colors and sizes. | 03-20-2014 |
20140022512 | PHOSPHOR-BASED LAMPS FOR PROJECTION DISPLAY - A phosphor-based lamp includes a phosphor material and an excitation source, which may be a laser or an LED, or both. Preferably, the lamp includes a recycling collar to reflect and recycle high angle light to increase brightness. Preferably, when the excitation source is a laser, a beam splitter redirects the laser beam to direct the laser beam through the recycling collar aperture onto the phosphor material. Light emitted by the phosphor material which exits the aperture passes through the beam splitter as the output of the lamp. Alternatively, lenses are used to redirect the laser beam around the recycling collar towards the phosphor material. Preferably, a plurality of excitation lasers are disposed around the recycling collar and aimed either to direct their outputs onto the phosphor material or toward an opposing wall, where the outputs are reflected onto the phosphor material. Such lamp may be used as part of a projection system. In one embodiment, the phosphor material is contained on the color wheel. | 01-23-2014 |
20110075105 | MULTIPLEXING LIGHT PIPE HAVING ENHANCED BRIGHTNESS - Multi-color light sources are mixed in a recycling housing to achieve high light output. In one embodiment, the light from each color light source, such as from red, green and blue LEDs, is multiplexed together and a portion of the mixed light passes through an output aperture in the light pipe. A portion of each colored light is recycled back, for example, by a shaped reflective surface and/or a reflective coating adjacent the aperture. The shape of the reflective surface is such as to direct each color of light back to a specific location to maximize the ultimate output light. In one embodiment, the light is directed back from the output side of the housing to an input light source having the same color. In another embodiment, the light is directed back from the output side of the housing to a coating designed to reflect that color light. The reflected light is then reflected back toward the output aperture and a portion of that reflected light is again reflected toward the input and impacts the original source for that color light. In this way, the light (at least in theory) recycles infinitely, thereby increasing the total light output of the housing. In some embodiments, the light is recycled using polarization and in some embodiments the input light is collimated. | 03-31-2011 |
20090129118 | Multiple lamp illumination system - An illumination system including a plurality of lamps, a plurality of first light reflectors, a plurality of second light reflectors, and an output light guide. Each of the first light reflectors is arranged to reflect light output from one of the lamps onto an input of one of the second light reflectors, which in turn is arranged to direct light from an output of one the first light reflectors into an input of the output light guide, such that the outputs of each of the lamps is combined into a single output. | 05-21-2009 |
