    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： 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： 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.

    摘要： Lighting controller including control system having first control facility and second control facility. First and second control facilities respectively are for controlling first and second visible-light sources including first and second pluralities of semiconductor light-emitting devices spaced apart from and along longitudinal axis. First and second visible-light sources respectively are positioned for directing first and second beams of first and second visible-light emissions from first and second pluralities of semiconductor light-emitting devices in first and second beam directions. First and second control facilities respectively are programmed for controlling first and second intensities of first and second beams of first and second visible-light emissions. Control system is programmed for modulating first intensity of first beam and second intensity of second beam in manner for causing first and second beams of first and second visible-light emissions to collectively emulate progression of ambient sunlight. Lighting systems and lighting control methods.
