Abstract

A lighting system for passenger cabins, particularly aircraft passenger cabins, is equipped with at least one central light source cooperating with hollow light guides for distributing light in the passenger cabin. The light sources may be positioned in fixed locations within the aircraft or in fixed locations in the ceiling or in mobile locations within the hollow light guides. Light extractors are positioned where needed. The light guides are hollow preferably tubular light guides which may cooperate with optical light conductor fibers, and with lenses and mirrors where needed.
