  • Publication number: 20030197113
    Abstract: The present invention provides an illumination management system that includes a first LED that outputs a first signal when exposed to a first spectrum of light, the first signal indicating an intensity of light from the first spectrum; a second LED that outputs a second signal when exposed to a second spectrum of light, the second signal indicating an intensity of light from the second spectrum and wherein the second spectrum includes at least some wavelengths that are not in said first spectrum. In some embodiments, more LEDs could be included in the system for associating the presence of light energy from different parts of the light spectrum. Also included is light control circuitry, coupled to the LEDs, configured to generate a lighting control signal that can be output to one or more lights to adjust the lights to a desired light level, wherein the lighting control signal varies in response to said first and second signals.

  • Patent number: 6555966
    Abstract: The present invention provides a lighting control circuit having a light sensor that outputs a first signal in response to being exposed to radiation. The lighting control circuit has a detection circuit that is coupled to the light sensor and is configured to generate a second signal from the first signal. The lighting control circuit has a driver circuit that is coupled to the detection circuit and is configured to generate a third signal to control an illumination level of a light, wherein an amplitude of the third signal is varied in response to the second signal and a reference signal. The lighting control circuit also has a shifting reference circuit configured to shift a reference voltage of the driver circuit to compensate for a supplemental sunlight energy contributed to the ambient light in a room.
