Patent ID: 7828463

Claim:
A lunar resonant lighting system, including: illumination means for casting a variable intensity illumination; power supply means for supplying operating power to said illumination means; sensor means for detecting moonlight in the night sky and generating a moonlight signal that varies with the intensity of moonlight; said power supply means receiving said moonlight signal and varying said operating power in an inverse relationship to said intensity of moonlight; said sensor means including at least one photosensor directed upwardly toward the sky generally at an elevation angle that is the complement of the latitude angle of the geographical location of said system; further including a pair of secondary photosensors directed generally toward the horizon and in diametrically opposed directions, said microprocessor being programmed to process signals from all of said photosensors to determine average background sky illumination and compare said average sky illumination to the strongest signal from any one of said photosensors to determine said intensity of moonlight.
