Abstract:
1. A solar light distribution system comprising: a first tubular member extending lengthwise along a central, longitudinal axis (CL1), said first tubular member having a first support wall defining a first light transfer duct, a first light receiving port, and a first light delivery port that are all optically coupled; a solar light concentrator affixed externally to said first tubular member and located proximate to the first light receiving port, said light concentrator for receiving solar light waves, processing the solar light waves into a collimated light beam, and directing the collimated light beam through the first light receiving port and into the first light transfer duct; a first turning reflector disposed inside of the first light transfer duct and located proximate to the first light receiving port, said first turning reflector for reflecting the collimated light beam from the light receiving port, down the first light transfer duct, approximately parallel to the central, longitudinal axis (CL1), to the first light delivery port; and wherein said solar light concentrator further includes a primary reflector having a reflecting surface that is defined by a segment of a parent paraboloid, said primary reflector being aspherical and having an off-axis configuration with an optical axis located at or near an edge of said primary reflector; a secondary reflector positioned adjacent to said primary reflector to receive solar light reflected by said primary reflector; and a collimating lens located adjacent to said secondary reflector for receiving solar light reflected by said secondary reflector.
