Abstract
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.
