The substrate is positioned on mounted on an outside surface of a window of a building and includes a first surface and an opposing second surface. The second surface faces the outside surface. The substrate is made of transparent material. The prisms are arranged on the first surface and parallel to each other. Each prism includes a flat side surface facing upward and a curved side surface facing downward. The flat side surface and the curved side surface extend from the first surface and intersect at a line away from the first surface. Each curved side surface is configured for reflecting light passing through the flat side surface to a ceiling of the building.
