ABSTRACT:
A solar greenhouse roof includes a plurality of relatively large sunlight reflectors which direct and receive sunlight to one or more relatively small focusing light reflectors. The light reflected from the focusing light reflectors is directed downward into the edges of plate glass pipe which are simply panes of plate glass mounted within the base of the roof. The glass pipes serve as a filter for blocking the transmission of ultraviolet and infrared light therethrough, thus allowing only visible light to reach such objects as plants located below the glass pipes. A protective Tedlar film or coated glass may be mounted atop the roof, the glass pipes may be aluminized on their planar surfaces to improve the internal reflectivity to visible light. Heat generated in the small reflector as well as in the glass light pipes due to the absorption of infrared light is carried away by coolant passing through the relatively small focusing light reflectors and through tubes which are in abutting relationship to the plane surfaces of the glass pipes.
