Abstract

Optics are provided for use in illumination devices the optics having a light guide, a redirecting layer including a plurality of lenses, and a plurality of reflector elements. Light from a light source enters the light guide and is guided therein until it escapes into a reflector element, which reflects at least some of the light received by the reflector element toward a corresponding lens for emission from the illumination device.
