Abstract
A high intensity LED based lighting array for use in an obstruction light with efficient uniform light output is disclosed. The high intensity LED based lighting array has a first concentric ring having a plurality of reflectors and light emitting diodes. The concentric ring has a planar surface mounting each of the plurality of reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes. A second concentric ring is mounted on the first concentric ring. The second concentric ring has a second plurality of reflectors and light emitting diodes. The second concentric ring has a planar surface mounting each of the plurality of reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes. The second plurality of reflectors and light emitting diodes are offset from the reflectors and light emitting diodes of the first concentric ring.
