Daylight redirecting window film employing embedded microstructures
A daylight redirecting window film having a layered structure with a total thickness of less than one millimeter and having a first optically transmissive film, a second optically transmissive film approximately coextensive with the first optically transmissive film, an intermediate layer of a relatively soft optically transmissive material disposed between the first and second optically transmissive films, a parallel array of linear three-dimensional structures formed in a space between the first and second optically transmissive films, a layer of an optically transmissive adhesive coating a surface of the first optically transmissive film, and a two-dimensional pattern of light scattering surface microstructures formed in an outer surface of the second optically transmissive film. The parallel array of linear three-dimensional structures defines a parallel array of linear channels, and each of the linear three-dimensional structures has a total internal reflection wall extending transversely through a portion of the layered structure.
