Abstract

A light guide with optics guides light exiting the guide. The device achieves accurate control of the reflected light by extracting light from a limited area of the light guide. The configuration of the reflectors used for the selective extraction determines the nature of the output light. The reflectors may be located on a side of the light guide opposite to an output side of the light guide.
