Claim 8:
9. An asymmetric total internal reflection (“TIR”) lens comprising an elongate body formed at least in part of light transmissive material, wherein:
the elongate body is defined by a first elongate planar surface and a second elongate planar surface, the second elongate planar surface being spaced from the first elongate planar surface, wherein the first and second elongate planar surfaces at least partially define a volume of the asymmetric TIR lens; and
wherein the elongate body is further defined by a plurality of surfaces that define a channel along a further edge of the elongate body, wherein the lens is configured to internally reflect light passing through the plurality of surfaces that define the channel outwardly and substantially only through the first elongate planar surface to form a plurality of overlapping beams that substantially uniformly illuminate a surface oriented perpendicularly with respect to the first elongate planar surface along at a plurality of different distances from the elongate body.
