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.
