ABSTRACT:
A lens arrangement for redirecting beams of light which diverge in a generally conical pattern from a fixed light source comprises a lens member configured and located relative to the light source for passing the diverging beams of light from the fixed light source therethrough substantially without changing the direction of the beams in a first plane, and for redirecting others of the diverging beams of light from the light source into substantially parallel beams of light as they pass through the lens member in substantially any one cross-sectional plane through the lens member which is substantially perpendicular with the first plane.
