ABSTRACT:
Optical films are disclosed, which have a structured surface including a plurality of concave pyramid-shaped structures, each structure having a base including at least two first sides and at least two second sides. In addition, optical devices are disclosed that incorporate the optical films, for example, such that a first surface of the optical film is disposed to receive light from a light source and the structured surface faces away from the light source.
