    摘要： A tunable lighting system comprising a plurality of channels comprising at least, a first channel for emitting blue light and having a wavelength peak between 420 nm and 480 nm, a second channel for emitting cyan light having a wavelength peak between 450 nm and 530 nm, a third channel for emitting cyan-green light having a wavelength peak between 510 nm and 590 nm, a fourth channel for emitting red light having a wavelength peak between 510 nm and 780 nm, and a multichannel driver for driving a selection of said plurality of channels, said multichannel driver is configured to drive each channel independently such that said light system emits an emitted light with a CRI of at least 85 over a CCT range greater than 3000 K.

    摘要： Lighting system including bowl reflector, visible-light source, central reflector, and optically-transparent body. Bowl reflector has central axis, and rim defining emission aperture, and first visible-light-reflective surface defining portion of cavity in bowl reflector. First visible-light-reflective surface includes parabolic surface. Visible-light source is located in cavity and configured for generating visible-light emissions from semiconductor light-emitting device. Central reflector includes second visible-light-reflective surface, having convex flared funnel shape and having first peak facing toward visible-light source. Optically-transparent body has first base being spaced apart from second base and having side wall extending between first and second bases. Concave flared funnel-shaped surface of second base faces toward convex flared funnel-shaped second visible-light reflective surface of central reflector. First base includes central region having convex paraboloidal-shaped surface and second peak facing toward visible-light source.

    摘要： Aspects of the present disclosure relate to a lighting device that is configured to provide light with a high color rendering index (CRI) value and/or uniform planar illumination. The lighting device may include a circuit board, a light emitting diode (LED) mounted to the circuit board and configured to emit broad spectrum light having a first CRI value, a photo-luminescent material disposed above the LED mounted to the circuit board configured to increase the CRI of the broad spectrum light emitted by the LED from the first CRI value to a higher, second CRI value, and an elastomer encapsulating at least part of the circuit board. Additionally, the lighting device may include a lens disposed over the LED configured to increase the maximum emission angle of light from the LED and a diffuser disposed above the lens and configured to diffuse the broad spectrum light.

    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.
