Abstract
Interior lighting and illumination systems for aircraft, particularly commercial passenger airplanes. Opposing pairs of LED lamps are positioned in the ceiling panels above the aisles between sets of seats in the passenger cabins. One set of LED lights are directed to illuminate the ceiling panels and may be in a particular color. The other set of LED lights are positioned to shine their lights on storage/stowage bins positioned across the aisles, thus creating a cross-bin lighting system. This enhances the cabin architecture and provides cabin illumination. A reflector can be positioned to direct the light and reduce possible glare to the passengers. The reflector directs the light rays from the LED lights which emanate from the top of the reflector to shine on the lowest part of the bins. The light rays leaving the reflector cross in front of the reflector.
