Abstract
A light transmissive substrate that transforms light having a Lambertian distribution includes a substrate having a plurality of microstructures on a first surface, where each of the plurality of microstructures comprises an array of folded micro-pyramid microstructures, wherein each folded micro-pyramid microstructure comprises a base section with a roof angle and a recess being formed in a shape of a micro-pyramid and comprising a recess roof angle, wherein light having a Lambertian distribution that enters the first surface of the substrate is transformed into light having a distribution with a maximum intensity at an angle away from nadir and a minimum intensity at nadir that exits a second surface of the substrate.
