Abstract: A method for concentrating light includes converting each section of a plurality of distinct collinear sections of incident illumination into a respective one of a plurality of collimated beams. The plurality of collimated beams forms a beam-array having an initial beam-array width in an incidence plane that intersects each of the plurality of distinct collinear sections. The method also includes decreasing a width of the beam-array from the initial beam-array width to a concentrated beam-array width that is less than a total width of the plurality of distinct collinear sections in the incidence plane.

Abstract: A solar light system may include two stages of optical concentration with intermediate removal of infrared radiation between the optical concentration stages. A second stage of optical concentration may prepare multiple concentrating beams of processed solar radiation with visible light with each such concentrating beam directed to a different corresponding light conduit for transmission to an interior space for interior lighting. System modularization may provide flexibility to accommodate a variety of interior lighting applications.
