NOVELTY - A solar radiation collection and distribution system has solar collection system having pivotable planar reflector, and primary and secondary reflectors fixed in an assembly pivotable in elevation and rotatable in azimuth so that the primary reflector continuously tracks the sun. The planar reflector reflects downwardly the beam from the secondary reflector pivots at one half the angular rate at which the assembly pivots.    USE - As solar radiation collection and distribution system.    ADVANTAGE - The inventive system minimizes transmission losses in the solar radiation collection system at sun elevation angles above 75degrees. It maximizes and efficiently collects, collimates, spectrally separates and distributes solar radiation at all latitudes and sun elevation angles.    DETAILED DESCRIPTION - A solar radiation collection and distribution system comprises a solar collection system (100). The solar collection system has a primary reflector (10) having an aperture (16), and a secondary reflector for redirecting radiation received from the primary reflector along an optical axis (15) through the aperture in a concentrated beam. The primary and secondary reflectors are disposed in a pivotable assembly. The beam has an exit angle with respect to the assembly different from the incidence angle of solar radiation incident on the primary reflector. An actuator (29) is provided for pivoting the assembly at an angular rate so that the primary reflector continuously tracks the sun. A motor (36) is provided for annularly rotating the assembly so that the primary reflector continuously tracks the sun azimuthally. A pivotable planar reflector (14) is provided for receiving and reflecting downwardly the beam received from the secondary reflector. It pivots about a pivoting axis at one half the angular rate. The downwardly reflected beam consists of sunlight and maintained in a constant vertical and horizontal orientation independent of the elevation and azimuth of the assembly.
