Abstract
A luminaire includes a plurality of solid state light sources arranged to emit light in respective angular distributions that are centered along a common optical axis. A reflector including one or more reflecting surfaces is arranged along a periphery of the solid state light sources. The reflector is positioned to receive light emitted at relatively high propagation angles from the solid state light sources, with respect to the optical axis, and reflects the light to have reduced propagation angles, with respect to the optical axis. The one or more reflecting surfaces have a generally flat cross-section that is angled away from the optical axis, and are arranged in a pattern around the periphery of the solid state light sources. The one or more reflecting surfaces can reflect specularly or diffusely.
