Paper Abstract

Since the invention of the flashlight in the late nineteenth century, it has proven indispensable for both civilian and military use. To date, the prevailing optical element used for collecting and concentrating light from the source has been the paraboloidal reflector. The advent of LED light sources, recent theoretical developments in nonimaging optics and advances in polymer optics are revolutionizing flashlight optics. We present new classes of optical solutions that provide superior efficiency, beam shaping, and active beam control. These solutions are patent pending.
