ABSTRACT:
A lens has a main body for use with at least one light source. The main body has a light-emitting face, a light-collecting face disposed opposite the light-emitting face, and a plurality of focal points, the latter of which form a focal ring. A central axis extends through the light-collecting face and the light-emitting face. The main body is substantially radially symmetrical about the central axis and the focal ring extends around the central axis of the main body of the lens.
