First Claim
1. A composite multilayer construction comprising:
- a window on the exterior surface of a building and adjacent to a room or a corridor, comprising;
a first glazing substrate; and
a solar light redirecting construction disposed on the first glazing substrate, wherein the solar light redirecting construction comprises;
a visible light diffusing layer; and
a light redirecting layer, wherein the layers are laminated together, and wherein the light redirecting layer comprises a major surface with a microstructured surface, the microstructured surface comprising forming a plurality of prism structures wherein the plurality of prism structures comprises a plurality of asymmetric prisms.

Abstract
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.
