摘要
A light transmissive structure includes a light transmissive substrate having first and second opposing faces and array of microprism elements on the first face, with a respective microprism element including a plurality of concentric microprisms. 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.
