Interior lighting and illumination systems for aircraft, particularly commercial passenger airplanes. Efficient beam forming optical light emitting diode arrangements having offset apertures for maximizing effectiveness are positioned in the ceiling panels above the aisles between sets of seats in the passenger cabins for cross bin illumination of stowage areas. The efficient beam forming optical LED devices are positioned to shine on opposite storage/stowage bins and are positioned to overcome line of height light source restrictions such as may be imposed by a valence. The devices are effective for illuminating across the aisles, thus creating a cross-bin lighting system.
An illumination system for a ceiling structure of an airplane having at least a first row of stowage bins adjacent said ceiling structure, said illumination system comprising:
A method for illuminating the ceiling structure of an airplane having at least a first row of stowage bins adjacent said ceiling structure, said method comprising:
