摘要： The present disclosure provides systems for generating tunable white light. The systems include a plurality of LED strings that generate light with color points that fall within red, blue, short-blue-pumped cyan, and long-blue-pumped cyan color ranges, with each LED string being driven with a separately controllable drive current in order to tune the generated light output. Methods of generating white light by combining light generated by red, blue, short-blue-pumped cyan, and long-blue-pumped cyan color channels. Methods of generating white light points at substantially the same 1931 CIE chromaticity diagram color coordinates having different EML.

摘要： The present disclosure provides lighting systems, which may be semiconductor light emitting devices, with two or more of blue, red and/or LRNE, short-blue-pumped cyan, long-blue-pumped cyan, yellow, and violet channels. The lighting systems can have a plurality of operational modes that provide different biological effects while having good color rendering capability. The yellow and violet channels can include violet LEDs and be used in operational modes that provide white light with lower EML values relative to operational modes using three or more of the blue, red, short-blue-pumped cyan, and long-blue-pumped cyan color channels.
