Abstract

A light source destructuring and shaping device which both homogenizes and imparts predetermined directionality to light rays emanating from a light source is disclosed. The device comprises a micro-sculpted surface structure which controls the direction in which light propagates in either reflection or transmission. The sculpted surface structure also homogenizes light propagating through it with predetermined directionality. The device may be used in an almost unlimited number of applications which require homogenization and which would benefit from being able to impart directionality to light waves propagating from a light source. These applications include existing diffuser applications and applications wherein it was not practical to use conventional diffusers. The homogenizing and shaping device achieves these benefits with very high transmission or reflection efficiency and with reduced side lobes.
