摘要： 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.

摘要： The present disclosure provides methods for generating tunable white light with controllable circadian energy performance. 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. Different light emitting modes can be selected that utilize different combinations of the plurality of LED strings in order to tune the generated white light.

摘要： Display systems for displaying digital content. The display systems have one or more LED-based lighting channels adapted to generate a circadian-inducing blue light output in first operational mode and a less-circadian-inducing blue light output in a second operational mode. The circadian-inducing blue light can have a first circadian-stimulating energy characteristic related to the associated first spectral power distributions of light generated in the first operational mode, and the non-circadian-inducing blue light can have a second circadian-stimulating energy characteristic related to the associated second spectral power distribution of light generated in the second operational mode. Disclosure methods of generating digital display content with the display systems described herein. The methods can generate a circadian-inducing blue light output in first operational mode and a less-circadian-inducing blue light output in a second operational mode.
