Abstract:

A primary reflector formed as a modified pyramid having a polygonal base located in open exposure to the sun has faces above the base which include reflecting surfaces that intersect at obtuse angles along lines lying in planes perpendicular to the base. The reflecting surfaces form a dihedral and are constructed of an externally mirrored material to reflect light impingent thereon into a concentrated field of reflection. At least one and preferably a plurality of secondary reflectors are located within the concentrated field of reflection and are oriented to return light reflected from the dihedral surfaces to the apex of the pyramid. A solar energy collector is located at the apex of the primary reflector to concentrate solar energy reflected first from the primary reflector and then from the secondary reflectors. The secondary reflectors may either be stationary within the path of movement of the concentrated field of reflection, or driven to follow the concentrated field of reflection as it moves throughout a solar day.
