Abstract
A device has a carrier and an optical element supported by the carrier. The optical element has a macro-optical characteristic and at least one surface. A light shaping surface microstructure is integral on the surface of the optical element. The microstructure homogenizes, shapes and controls directionality of light emanating from the surface of the optical element to produce a smooth, consistent and continuous pattern of light in a predetermined distribution shape and direction. The optical element can either transmit or reflect light incident on a portion of the device and the optical element.
