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.

摘要： Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.

摘要： According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, an LED mounted to the circuit board that is configured to emit light with an angular CCT deviation, a lens assembly mounted to the circuit board over the LED and configured to receive the light emitted from the LED and reduce the angular CCT deviation of the light received from the LED to make a color temperature of the light received from the LED more uniform, and an elastomer encapsulating at least part of the circuit board that is separate and distinct from the lens assembly.

摘要： The present disclosure provides bioactive lighting systems suitable for generating white light. The lighting systems has lighting channels configured to produce white light having a color point and a spectral power distribution. The combination of emissions from selected channels results in white light having adjusted color points. The system is controlled to selectively increase or decrease CSE and to selectively provide LRNE.

摘要： Lighting system including visible-light source, optical system, mounting system, and control system. Visible-light source includes plurality of semiconductor light-emitting devices (SLEDs) and selectably generates: visible-light emissions having cyan-ish color point; and visible-light emissions having orange-ish color point. Optical system and mounting system are integrated with visible-light source. Optical system is arranged to combine together, into combined light emissions, visible-light emissions from SLEDs among plurality of SLEDs. Mounting system is arranged for directing combined light emissions as up-light emissions. Control system is coupled with visible-light source and selectably causes visible-light emissions to have cyan-ish color point or orange-ish color point. Control system and optical system cooperatively form combined up-light emissions as having dynamic spectrum for emulating orange-ish sky color at time of day selected to represent sunrise sky or to represent sunset sky, changing over time for emulating cyan-ish sky color at another time of day selected to represent mid-day sky.
