Abstract
An illumination technique and system employing an optical waveguide to transmit light from a source, typically a light emitter which operates at high temperature, to a light head which creates a desired light dispersion pattern. The light head includes a member which emulates the light source and the emitted light is coupled from the source into the optical waveguide by a compact and efficient columnator comprising a pair of dissimilar three dimensional reflectors and a lens.
