Abstract: A light engine for a high intensity light that may be compliant with FAA or ICAO standards is disclosed. The light engine includes a first light emitting module having a light emitting diode mounted in a horizontal plane. A reflector has a reflective surface in perpendicular relation to the light emitting diode. The reflective surface is defined by combining the integrals of a required beam emission specification with the integrals of the light emitting diode. The resulting reflective curve is modified with focal length and curve based on horizontal plane position variables relative to the light emitting diode around an azimuth angle.

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. At least some of the first plurality of reflectors are adjustable relative to the position of the respective light emitting diode to produce a precise beam pattern from the light emitting diode.

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.

Abstract: A heat sink for use with a high output LED light source is disclosed. The heat sink is used with an LED and conical reflector. The heat sink has a cylindrical back end holding the light emitting diode. The heat sink includes a conically shaped wall having an inner and outer surface and an open front end. The open front end has a rim with notches. The reflector has a front flat surface with arms which are fixed in the notches with a fastener. The heat sink includes a plurality of slits formed on the inner and outer surfaces extending between the back and front ends. A plurality of vanes extend radially from the inner surface. The heat sink is fabricated from a thermally conductive material. The conical shape of the heat sink, the slits and vanes increases exposed surface area to assist in dissipating heat generated from the LED.
