Abstract:

An anti-collision light for large, commercial aircraft is disclosed. The light is a self-contained unit capable of easy replacement of any anti-collision light currently in use in any large aircraft using an adapter plate and adapter cable directly connected to 115 VAC 400 cycles from the aircraft. The light includes a plurality of round circuit boards with an annular ring of high intensity, surface mounted LEDs, with a disk having an edge configured as an offset half parabolic reflector made up of a plurality of conical facets. Angles of the conical facets are selected such that light from the LEDs is focused into a plurality of discrete planes from each facet, these planes concentrating the light into planar regions of discrete light intensity as required by the FAA. The disks with reflector edges also serve as heat sinks to dissipate heat developed by the LEDs.
