Abstract
A light guide illumination system having a metal-halide double-ended illumination source is disclosed. The light guide illumination system includes at least one light guide and two curved reflectors disposed in proximity to the double-ended illumination source. The two curved reflectors are adapted to reflect the emitted light from the double-ended illumination source into the light guide. The light guide illumination system further includes at least one multi-sectored lens adapted to receive light from the light guide, and at least one output light guide. The multi-sectored lens is adapted to receive the reflected light from the light guide and to focus the light into the output light guide.
