ARCHITECTURE AND METHOD FOR AIRCRAFT LIGHTING SYSTEM USING A CENTRALLY LOCATED RED, GREEN, AND BLUE (RGB) LIGHT SOURCE SUBSYSTEM AND A PLURALITY OF DISTRIBUTED PASSIVE LIGHT-HEADS

Abstract:

Systems and methods for an aircraft lighting system (ALS) are provided. The method includes co-locating a central light source subsystem including a blue light generator, red light generator, and green light generator, and a light generating control unit (LGCU) comprising a processor, and distributing a plurality of passive light-heads around an external surface of the aircraft. Each passive light-head of the plurality of passive light-heads is operationally coupled to a first side of a respective light switch of a respective plurality of light switches, the light switch being coupled on a second side to a light emitting output of the central light source subsystem. Controlling and actuating the light generators and the light switches in accordance with a load profile is performed by a light generating control unit (LGCU).
