Abstract
A panel for controlling light passage, suitable for use as a windscreen, a window pane, or as a windscreen portion of vertical, south facing solar collection devices. The panel includes finned portions arranged to receive light falling upon the windscreen in amounts dependent upon the angle of incidence of the light onto the windscreen. The fins form portions of prisms or refractive elements which serve to refract the light in a direction tending to inhibit the passage of the light through the windscreen. In one embodiment, the finned portions are attached extending inwardly from a smooth planar surface. In two other embodiments the finned portions interconnect planar surfaces to form a saw-tooth or 'Z' configuration, and constitute a structure which can be easily fabricated. All of the embodiments, when used to control the passage of sunlight, can be configured to permit the passage of winter sunshine, to inhibit the passage of summer sunshine, and to control the passage of spring and fall sunshine to an extent dependent upon its angle of incidence onto the windscreen.
