Abstract

The exemplary aircraft anticollision beacons are constructed around a faceted aluminum support structure. The support structure has a cylindrical central post portion with an outside surface having at least six vertically oriented substantially planar faces. An array of LEDs is mounted in thermally conductive relationship on each face of the central post portion. Each LED is partially surrounded by a trough-shaped reflecting surface that re-directs off axis light into a horizontal plane. Adjacent trough-shaped reflecting surfaces combine to form annular reflecting troughs that extend around the circumference of the central post portion. The support structure defines a thermal pathway from the LEDs to a heat radiation surface on the base portion. The base portion is also configured to act as a heat sink for heat generating components of the LED driver circuits.
