Publication number: 20230330383Abstract: Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.Type: ApplicationFiled: November 28, 2022Publication date: October 19, 2023Inventors: Michael R. Krames, Aurelien J. F. David, Emil Radkov, Willem Smitt
