Abstract

A light transmissive structure includes a light transmissive substrate having first and second opposing faces and array of microprism elements on the first face. A respective microprism element includes at least one ring comprising a plurality of microstructure pyramids that is rotated randomly and/or pseudorandomly on the first face about an axis that is orthogonal to the substrate relative to at least one other microprism element. The light transmissive structure is configured to receive light from a light source facing the first face and distribute the light emerging from the second face in a 2D batwing distribution.
