Abstract
The present disclosure provides lighting systems, which may be semiconductor light emitting devices, with two or more of blue, red, 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. The yellow, red, and violet channels can be used in an operational mode to provide low EML values while providing white light between about 1800K and about 3500K CCT.
