Abstract
An apparatus comprises a light source, preferably an LED, a reflector, a light-conducting element mounted on the light source for directing light from the light source to an end of the light-conducting element, and a lens mounted on the end of the light-conducting element for directing light into a central beam. Light from the light source is directed to the reflector into a peripheral beam. The central and peripheral beams comprise substantially all of the light generated by the light source. The lens is in effect mounted on a pedestal above the LED. The pedestal transmits all the light rays in the central solid angle to the lens without loss.
