ABSTRACT:
An apparatus is comprised of a light source radiating into a peripheral forward solid angle and a center forward solid angle. A reflector is positioned to reflect light from the light source from the peripheral forward solid angle into a longitudinal beam about an optical axis of the reflector. A lens is disposed longitudinally forward of the light source for focusing light into a predetermined beam pattern from the center forward solid angle into a skewed beam in a skewed direction with respect to the optical axis of the reflector to project a composite beam of light comprised of the light radiated in the skewed beam and the longitudinal beam.
