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： System for determining periodic values of phase angle Φ of waveform power input including voltage detector for detecting periodic values of average voltage of waveform power input and detecting corresponding periodic values of peak voltage of waveform power input. System also includes phase angle Φ detector in signal communication for receiving periodic values of average voltage and peak voltage from voltage detector. Phase angle Φ detector also detects periodic values each being ratio of one of periodic values of average voltage divided by corresponding periodic value of peak voltage, or being ratio of peak voltage divided by average voltage; and determines periodic values of phase angle Φ of waveform power input corresponding to periodic values of ratio. Lighting systems.

摘要： The present disclosure provides methods for generating tunable white light. The methods include using a plurality of LED strings to generate light with color points that fall within white, 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.

摘要： Lighting system including light source having semiconductor light-emitting device configured for emitting light having first spectral power distribution along central axis. System includes volumetric lumiphor located along central axis configured for converting some light emissions having first spectral power distribution into light emissions having second spectral power distribution. System may include visible light reflector having reflective surface and being spaced apart along central axis with volumetric lumiphor between semiconductor light-emitting device and visible light reflector. Reflective surface may be configured for causing portion of light emissions to be reflected by visible light reflector. Exterior surface of volumetric lumiphor may include concave exterior surface configured for receiving a mound-shaped reflective surface of visible light reflector. Volumetric lumiphor may have exterior surface that includes: concave exterior surface forming gap between semiconductor light-emitting device and volumetric lumiphor; or convex or concave exterior surface located away from and surrounding central axis.

摘要： A field replaceable power supply cartridge is provided for coupling with a socket. The cartridge has a latch mechanism that can be actuated by the user to couple the cartridge to the socket, such that latches of the cartridge releasably engage recessed portions in the socket. The cartridge has a key feature that corresponds to a key feature on the socket, allowing the cartridge to be coupled to the socket in only one orientation, thereby preventing the incorrect electrical connection between the cartridge and the socket. The cartridge can have a multi-pin electrical connector for coupling to a corresponding connector on the socket. The socket can be a relatively short socket, where the electrical wires are bottom fed, or can be a relatively tall socket, where the electrical wires are side fed via one or more openings in the body of the socket.
