Abstract
A quickly deployable and reconfigurable light emitting diode (LED) lighting apparatus with high output intensity and precisely controlled beam property is disclosed for navigational aids. The lighting apparatus comprises an array of high intensity LED units with their light beams individually controlled by secondary optical systems. The transformed light beams mix in a pre-determined manner to produce an illumination pattern with desired intensity distribution. The LED lighting apparatus may further comprise a micro-controller, a plurality of sensor elements, and a wireless transceiver for remote monitoring and control. The lighting apparatus can be powered by rechargeable batteries for temporary or semi-permanent lighting. It can also be powered by standard power lines for permanent lighting.
