  • Patent number: 10674581
    Abstract: The described embodiments relate to multichannel luminaires (102, 212, 404) that employ a color coefficient matrix (CCM) that can be used to adjust an operation of the multichannel luminaires according to their contribution of light to an area (112, 402). The CCM can be generated based on images captured within the area and/or a software simulation that approximates the contribution of light from the multichannel luminaires to the area. Once the CCM has been generated, the CCM can be used to compensate control signals to each multichannel luminaire in order to provide more accurate color rendering and uniform light distribution. Furthermore, feedback from embedded sensors (206) in the multichannel luminaires and/or sensors (116, 208, 210, 418) in the area can provide further basis for compensating control signals according to the qualities of the natural and artificial light entering the area, and the effects of different surfaces (128) on the light.

  • Publication number: 20100254155
    Abstract: Simulated candles and methods of simulating a candle are disclosed. The simulated candles include a cylindrical housing having an open top, a plurality of LEDs positioned in the housing, a plurality of optical fibers positioned to receive and transmit light from the plurality of LEDs through the open top of the housing, and a translucent conical light diffuser mounted about the plurality of optical fibers to simulate the appearance of a candle flame. The housing may simulate a candle taper, and may include simulated wax drippings. The simulated candle may include a power source and control electronics positioned within the housing. The color of the LEDs is selected to provide the realistic appearance of a lit candle, for example, the appearance of historically accurate candle, such as, a spermaceti candle.
