Abstract

An infrared aircraft lighting system designed for use in connection with night vision goggles includes a ring structure containing infrared lights that is installed between an existing visible light beacon and the aircraft outer surface, without requiring modification of either the aircraft structure or the existing visible light beacon. A central opening in the ring is aligned with the opening in the aircraft that was created to receive the visible light beacon. A plurality of holes extending through the ring structure permit the mounting bolts passing through a flange on the beacon light to extend on into the aircraft, thus securing both the visible light beacon and the ring structure on the aircraft. A plurality of infrared lights are mounted on said ring structure in a circular pattern so as to be visible from above. A slot formed in the ring'"'"'s lower surface accommodates the electrical wiring necessary to supply power to the infrared lights.

Claims

1. An infrared beacon lighting system for use on the exterior of aircraft in combination with an existing visible light beacon comprising:

a ring structure having generally planar exterior and lower surfaces, and a central opening the diameter of which is large enough to permit the free passage therethrough of an existing beacon light;

means forming a plurality of holes through said ring structure for receiving the mounting bolts that secure the beacon light to the aircraft,

a plurality of infrared lights, and

means for mounting said infrared lights on said ring structure.

2. The infrared beacon lighting system of claim 1 wherein said mounting means includes means forming a plurality of openings in said ring structure exterior surface into which the infrared lights are placed so as to be viewable from above the plane of the exterior surface.

3. The infrared beacon lighting system of claim 1 further including means forming a slot in said ring structure lower surface through which electrical wires are placed to connect said infrared lights to a source of power.

4. An infrared beacon lighting system for installation between an existing visible light beacon on an aircraft without requiring modification of the aircraft structure comprising

a ring structure having generally planar exterior and lower surfaces, and a central opening the diameter of which is large enough to permit the free passage therethrough of an existing beacon light;

means for mounting said ring structure and the beacon light to the aircraft, and

a plurality of infrared lights in generally equally spaced intervals mounted on said ring structure.
