Methods For Generating Tunable White Light With High Color Rendering

The present disclosure provides methods for generating white light. The methods use a plurality of LED strings to generate light with color points that fall within blue, yellow/green, red, and cyan color ranges, with each LED string being driven with a separately controllable drive current in order...

Zusammenfassung:	The present disclosure provides methods for generating white light. The methods use a plurality of LED strings to generate light with color points that fall within blue, yellow/green, red, and cyan color ranges, with each LED string being driven with a separately controllable drive current in order to tune the generated light output.
