Abstract
Systems and methods for improving color accuracy and uniformity in LED illumination systems are disclosed including light engines and switching circuits for controlling the addition or subtraction of light from one or more color light sources of the light engines to produce light of a uniform and consistent color. Systems and methods of providing LED light engines and associated illumination spectrums that are both visually appealing and rich in melanopic flux are also disclosed.
