Abstract
A central lighting system for providing light to locations remote from a light source includes first and second ellipsoidally shaped reflectors joined together to surround the light source. The first and second reflectors direct the light from the light source to light guides which are fixed at a position outside of the joined together reflectors. The ellipsoidally shaped reflectors each have an opening or window along an optical axis through which the reflected light passes to the light guides. The configuration of the reflectors allows the light the be received by the light guides outside of the reflectors. A base secures the light source in a fixed position with respect to the reflectors and allows the light source and reflector module to be removed and replaced as a single unit without repositioning the light guides.
