  • Publication number: 20210290973
    Abstract: Methods and apparatus for circadian lighting are disclosed. In particular, improved lighting is described in relation to a novel definition of an optimum relative circadian spectral sensitivity distribution (“Circadian Potency SSD”) with a peak sensitivity at approximately 470 nm-480 nm (preferable embodiments at 472 nm or 478 nm) with a full width at half maximum (“FWHM”) of approximately 50 nm which is skewed asymmetrically between approximately 440 nm and approximately 490 nm. Methods and approaches to determine the Circadian Potency of light sources from their spectral power distributions (SPD) and use the CircadianPotency SSD to optimize healthy circadian function under normal indoor and outdoor illumination conditions are described herein, and incorporated into various light sources, including white light sources, dimmable light sources, and daytime/nighttime light sources.

  • Patent number: 10471231
    Abstract: Systems and methods for controlling environmental illumination relative to circadian function of individuals are provided. A method is provided for controlling the operation of light sources by assigning a circadian state to the individual based on received electronic information, extrapolating future circadian states based on the assigned circadian state, the assigned circadian state or the extrapolated future circadian states including at least a biological night state, and encoding machine-level control commands that control the operation of the light source for transmission to the light sources adapted for the biological night state by having circadian-significant attenuation along the circadian active wavelength range.

  • Publication number: 20150330599
    Abstract: A luminaire includes a plurality of solid state light sources arranged to emit light in respective angular distributions that are centered along a common optical axis. A reflector including one or more reflecting surfaces is arranged along a periphery of the solid state light sources. The reflector is positioned to receive light emitted at relatively high propagation angles from the solid state light sources, with respect to the optical axis, and reflects the light to have reduced propagation angles, with respect to the optical axis. The one or more reflecting surfaces have a generally flat cross-section that is angled away from the optical axis, and are arranged in a pattern around the periphery of the solid state light sources. The one or more reflecting surfaces can reflect specularly or diffusely.

  • Publication number: 20150276145
    Abstract: A luminaire is provided to redirect incidence light from one or more solid state light sources to a batwing distribution with both tunable peak angle and beam width. The peak angle is able to be tuned from 90 degree to 0 degree from the incidence direction with very high efficiency. The beam width is able to be tuned with either narrow beam angle solid state light sources for high efficiency or TIR lens or the optical properties of a reflector for versatility. Uniform illuminance distribution is thus achieved across a wide field with or without a prism or diffuser cover.
