Abstract:

A solar heating system comprising a lens collector arrangement, an insulation area, and a storage section positioned in an enclosing structure, and an associated utilization means. The collector lens is an array of light guide lenses having alternate high and low refractive surfaces. The array is contoured in a capping relationship over a focusing lens to provide an extremely high concentration of solar energy irrespective of the angle of the sun. The light guide lenses increase by several orders of magnitude the amount of solar energy striking the surface of the focusing lens. The focusing lens is a plurality of flat surface type of lenses stacked one over the other in spaced relationship and operable to concentrate the solar energy to a central region. Surrounding the perimeter of the plurality of focusing lenses in an array, in a "wall" configuration, of light guide lenses similar in construction to the aforesaid capping light guide lenses. The angle of the reflective surfaces of the capping lenses and the wall lenses is such to receive and direct to the focusing lenses the maximum amount of radiation at all times of the day and season.
