Abstract
An aircraft exterior lighting multi-LED array for variable beam profile enables illumination of landing and taxi lights from a common fixture. An optic enables direction of luminance emitted from at least one central emitter (or cluster of emitters) along steradians illuminated when landing while directing luminance emitted from at least one peripheral emitter (or cluster of emitters) along steradians illuminated when taxiing.
Claims10
An aircraft exterior lighting multi-LED array enabling variable beam profiles for both landing and taxi lights upon an aircraft, said exterior lighting multi-LED array comprising:
- a fixture;
- at least one central emitter disposed centrally in the fixture under at least a first collimator;
- and
- at least one peripheral emitter disposed off-center in the fixture under at least a second collimator;
- wherein a single circuit controls switching between landing lighting and taxi lighting on the aircraft exterior by activating and deactivating the at least one peripheral emitter in lieu of, and in addition to, the at least one central emitter.
An aircraft exterior lighting multi-LED array enabling variable beam profiles for both landing and taxi lights upon an aircraft, said exterior lighting multi-LED array comprising:
- a fixture;
- at least one condenser interior to the fixture;
- at least one central cluster of emitters disposed within the condenser and centrally in the housing under at least a first collimator;
- and
- at least one peripheral cluster of emitters disposed within the condenser off-center in the fixture and under at least a second collimator;
- wherein a single circuit controls switching between landing lighting and taxi lighting on the aircraft exterior by activating and deactivating the at least one cluster of peripheral emitters in lieu of, and in addition to, the at least one cluster of central emitters.
