Abstract:
Lighting systems and methods for providing biologically optimized illumination throughout the day are disclosed. Systems and methods of providing LED light engines and associated illumination spectrums that are both visually appealing, rich in melanopic flux and that reduce blue light hazard exposure are disclosed. Embodiments of the invention relating to specific spectra of illumination containing high or low amounts of melanopic light, spectrally and spatially tunable LED lighting systems, programmed and automated controllers for temporally controlling bio-effective illumination, and dimming circuitry for tuning the spectral output of lighting devices are also disclosed.

Claim (Index 14):
A method for providing dynamic and time varying spectral illumination throughout a photoperiod to facilitate circadian rhythm regulation and mitigate social jet lag comprising the steps of:\n providing a light engine comprising a first LED operable to illuminate high efficacy white light, a second LED operable to produce illumination with a maximum peak intensity between 475 nm and 495 nm and a third LED operable to produce light that has a peak intensity at about 420 nm in the wavelength band between 400 nm and 450 nm; identifying a photoperiod corresponding to at least a portion of a daily human circadian cycle; and adjusting the spectral output of said light engine during said photoperiod to facilitate circadian rhythm regulation wherein the intensity of the illumination output from said second LED is increased and maintained near maximum during a daytime portion of the photoperiod to provide adequate melanopic light and decreased or eliminated during the nighttime portion of the photoperiod and wherein the illumination output of the third LED is varied from a first low level to a second higher level and then from the second higher level back to a lower level all over period not exceeding one hour at least once during the photoperiod.
