Abstract

A combined aircraft navigation and anti-collision light, includes: at least one navigation light source and one anti-collision light source; a navigation light sensor, in operation outputting a light detection signal corresponding to an amount of light detected by the navigation light sensor; first and second optical systems, associated with navigation and collision light sources, wherein the first optical system is configured for shaping a navigation light output from light emitted by the at least one navigation light source and is configured for directing stray light from the at least one navigation light source to the navigation light sensor and a second optical system, associated with the at least one anti-collision light source and configured for shaping an anti-collision light output from light emitted by the at least one anti-collision light source; a lens cover, arranged over the light sources and optical systems for passing light therethrough.
