Abstract
A system for focusing light on an illumination area. The system includes a reflector having a focusing reflective surface and a focal region and an LED array having a plurality of LEDs located within the focal region. Each of the plurality of LEDs in the LED array is positioned to emit light toward the focusing reflective surface. The focusing reflective surface reflects light from each of the plurality of LEDs of the LED array toward the illumination area.
