  • Publication number: 20210022221
    Abstract: 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. One or more of the LED strings can have ultraviolet or violet LEDs.

  • Patent number: 10827580
    Abstract: The present disclosure provides lighting systems suitable for generating white light. The lighting systems can have a first lighting channel configured to produce a first white light having a first color point and a first spectral power distribution, a second lighting channel configured to produce a second white light having a second color point and a second spectral power distribution, and a control system configured to independently change the intensity of each of the first lighting channel and the second lighting channel. The first lighting channels can have LEDs having an emission with a first peak wavelength of between about 440 nm and about 510 nm. The second lighting channels can have LEDs having an emission with a second peak wavelength of between about 380 nm and about 420 nm. The disclosure provides methods of generating white light using the lighting systems described.

  • Patent number: 10805998
    Abstract: 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.
