Patterns On Glass For Increased Light Transmission And/Or Light Trapping

摘要

In one non-limiting embodiment, a transparency for use as a cover plate for a solar collector, window and/or room divider includes a major surface of a glass substrate having Brewster tetrahedrons to convert s-polarized light waves to converted p-polarized light waves to reduce the percent of light wave reflectance of the substrate. In another non-limiting embodiment, the transparency includes a major surface of the substrate having pyramidal tetrahedrons to capture light waves within the body of the substrate to reduce the percent of visible light reflection.

主权项

1. A transparence for converting s-polarized light waves to converted p-polarized light waves, wherein the transparency comprises:
a transparent substrate having a first major surface and an opposite second major surface; a tetrahedron comprising points A, B, C and D, wherein a first triangular facet is defined by sides extending between points A-B-D and the sides of the first facet at the point A subtend a first angle and the sides of the first facet at the point B subtend a second angle, wherein the first and second angles are equal to one another; a second triangular facet is defined by sides extending between points A-B-C and the sides of the second facet at the point A subtend a third angle and the sides of the second facet at the point B subtend a fourth angle, wherein the third and fourth angles are equal to one another; a third facet is defined by sides extending between points B-C-D, and a fourth facet is defined by sides extending between points A-C-D, and the sides of the first facet lie in a plane of the first major surface of the transparent substrate and surfaces of each of the second, third and fourth facets have a reflective surface.
