Abstract

See full text

An optical system utilizing a light pipe in which light travels by total internal reflection (TIR) accurately controls the light exiting the pipe. The system achieves accurate control of the reflected light by selectively extracting light from a limited area of the light pipe. The configuration of the reflectors used for the selective extraction of the light determines the nature of the output light. The reflectors are preferably located on an output side of the light pipe. All light output by the system is directed by the reflectors.
