Abstract
A lighting fixture and lighting system for a transportation vehicle is disclosed that provides color variations for lighting the passenger cabin of an airplane, train, bus or other type of transportation vehicle. The lighting fixture and system further provide ultraviolet light that helps to disinfect the circulating air in the passenger cabin. A fixture in an exemplary lighting system provides visible light for lighting up the passenger cabin and germicidal ultraviolet light directed toward or into an output vent(s) of the air circulation system of the passenger vehicle. The ultraviolet light is segregated from the visible light such that ultraviolet light is only directed toward or into the circulation vents of the vehicle'"'"'s air circulation system.
