HYBRID LIGHT REDIRECTING AND LIGHT DIFFUSING CONSTRUCTIONS

摘要

Solar light redirecting glazing units include light redirecting and light diffusing constructions. The solar light redirecting glazing units may include a glazing substrate, a visible light diffusing layer, and a light redirecting layer oriented such that incoming solar light contacts the visible light diffusing layer before contacting the light redirecting layer. The solar light redirecting glazing units may include a glazing substrate, a patterned visible light diffusing layer, and a light redirecting layer. The solar light redirecting glazing units may include two glazing substrates separated by an intervening space with a solar light redirecting layer disposed on one glazing substrate, and a visible light diffusing layer disposed on the other glazing substrate.

1. A solar light redirecting glazing unit, comprising:
a first glazing substrate; a visible light diffusing layer disposed on the first glazing substrate; and a light redirecting layer adjacent to the visible light diffusing layer, the light redirecting layer comprising a major surface forming an ordered arrangement of a plurality of prism structures, and wherein the visible light diffusing layer and light redirecting layer are oriented such that incoming solar light contacts the visible light diffusing layer before contacting the light redirecting layer.
