ABSTRACT:
A light emitting diode (LED) signaling apparatus for navigational aids is provided. The signaling apparatus comprises a plurality of high intensity LEDs with their output beams individually controlled by high precision optical beam transformers. The transformed LED beams are mixed in a predetermined manner by controlling the relative position, angular orientation, and other parameters of the LEDs to produce a desired illumination pattern.
