Abstract
Provided systems and methods for an aircraft lighting system (ALS) include a centralized blue generator that supplies blue light to a plurality (N) of passive light-heads distributed at various locations on the aircraft. A load profile for use of the N passive light-heads during all flight phases and operational phases is developed and uploaded into the system. Each of the passive light-heads is operationally coupled to the blue light generator via a respective light transmission element that is gated with a respective one of N light switches. A light generating control unit (LGCU) is coupled to the blue light generator, and controls the generation and actuation of blue light, in addition to controlling light switch positions, as a function of navigation data and the load profile. Each of the N passive light-heads comprises a respective light conversion element to convert the blue light into red, green, or white light.
