Abstract

An obstruction lighting system includes a disc having a generally planar surface. A plurality of light emitting diodes are mounted to the planar surface of the disc, a central light emitting axis of the light emitting diodes being oriented generally perpendicularly away from the planar surface. A reflector is coupled to the disc, the reflector having an outer surface in the shape of a rotated conic section, the reflector further including a projecting portion. The outer surface of the reflector has an optical axis generally perpendicular to the central light emitting axis of the light emitting diodes. Furthermore, the projecting portion of the reflector blocks light emissions from the light emitting diodes in an upwardly direction from the obstruction lighting system. The disc and a lens retainer may be configured to block light emitted by the light emitting diodes from traveling in a downwardly direction from the obstruction lighting system.
