Abstract
An aircraft lighting system (ALS) and apparatus which includes: a lighting generator control unit (LGCU) controlling a light source generator for generating a first, second and third type of light to each passive light head; a light bus coupled to the light source generator to receive the first, second, and third types of light and for converting the first type of light to a fourth type of light; a plurality of light transmission elements coupled to the light source generator; a plurality of light switches responsive to a switch command from the LGCU to optically not direct or direct light from the light bus to a light transmission element; a light conversion element connected for converting the first type to the fourth type of light; and the LGCU configured to command the light source generator to generate light in accordance with a load profile.
