Abstract: A luminaire includes a light source (101), and a first free-form reflector (110) registered with the light source (101) and receiving non-collimated light (102) from the light source (101). A secondary reflector (120) is configured to receive the non-collimated light reflected from the first free-form reflector (110). A second free- form reflector (110) is configured to receive the non-collimated light reflected from the secondary reflector (120). A virtual source reflector (125) is registered with the second free-form reflector (110) and configured to receive the non-collimated light reflected from the second free-form reflector (110).

Abstract: The disclosure generally relates to concentrating daylight collectors and in particular to concentrating daylight collectors useful for interior lighting of a building. The concentrating daylight collectors generally include a cassegrain-type concentrator section that provides for a full-tracking solar collector with one moving part and with a high efficiency of coupling of collected solar irradiation to a stationary duct. In some cases, the disclosed concentrating daylight collectors can be used more conventionally, such as for directing sunlight onto a photovoltaic cell for generation of electrical power, or an absorbing surface for extraction of thermal energy.
