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 ring assembly having a plurality of reflectors and light emitting diodes. The ring assembly has a planar surface mounting each of the plurality of primary reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes. A secondary diffuser is positioned on the ring to mix light from the light emitting diodes to create a uniform light emission in a range of azimuth angles.
