Methods For Generating Melatonin-Response-Tuned White Light With High Color Rendering

摘要

The present disclosure provides methods for generating tunable white light with controllable circadian energy performance. The methods use a plurality of LED to generate light with color points that fall within blue, yellow/green, red, and cyan color ranges, with each LED being driven with a separately controllable drive current in order to tune the generated light output. Different light emitting modes can be selected that utilize different combinations of the plurality of LED in order to tune the generated white light.
