Abstract
A film which simultaneously maximizes light reflectivity from one side of the film while maximizing light transmissivity from the opposite side of the film. This is achieved by configuring the film with distinct regions of transparency and reflectivity where the extended boundary of the reflective region is shaped into a light funnel/pipe and where periodically placed discrete and/or extended/continuous shapes are created (such as extended triangular indentations, or discrete shapes such as a cone, a pyramid, or any polyhedron). The reflective region is composed of mirror-like material such as aluminum or silver, but may be a composite paste, a composite material, or multiple materials with different refractive indices or reflective qualities. In some embodiments, the reflective material is embedded in the transparent material such that the base of each shape is approximately parallel to and coincident with, or slightly recessed from the surface of the transparent material. In other embodiments, the reflective material is embedded in the transparent material such that the base of each shape is set at an angle to the surface of the transparent material. The transparent material will be continuous on at least one surface such that the transparent material forms the boundary for the film. The reflective regions and the transmissive regions may be configured according to application specification.
