ABSTRACT:
An LED or incandescent light source is positioned in a reflector arranged to reflect light from the LED or incandescent light source which is radiated from the LED or incandescent light source in a peripheral forward solid angle as defined by the reflector. A lens is disposed longitudinally forward of the LED or incandescent light source for focusing light into a predetermined pattern which is radiated from the LED or incandescent light source in a central forward solid angle as defined by the lens. The apparatus comprised of the combination projects a beam of light comprised of the light radiated in the central forward solid angle and peripheral forward solid angles.
