| Title: |
Optic System for Light Guide with Controlled Output |
| Abstract: |
A light guide with optics accurately controls the 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 are preferably
located on a side of the light guide opposite to an output side of the
light guide.
