1. A lens defining a central axis, said lens comprising:

  • a bottom surface;

    a first reflecting surface obliquely angled with respect to the central axis and extending from said bottom surface in a direction away from the central axis;

    a second reflecting surface obliquely angled with respect to the central axis; and

    a refracting surface obliquely angled with respect to the central axis and extending from said second reflecting surface in a direction toward the central axis;

    wherein light entering said lens through said bottom surface and directly incident on said first reflecting surface is reflected from said first reflecting surface to said second reflecting surface, is subsequently reflected from said second reflecting surface to said refracting surface, and is then refracted from said refracting surface to exit said lens and to form a first refracted light beam; and

    wherein light entering said lens through said bottom surface and directly incident on said second reflecting surface is reflected from said second reflecting surface to said refracting surface, and is then refracted from said refracting surface to exit said lens to form a second refracted light beam.
