Abstract

An optical waveguide comprising orthogonal x- and y-dimensions and developing an illumination distribution pattern comprising orthogonal x- and y-extents, comprising at least one coupling feature for directing light into the waveguide, at least one light redirection feature for redirecting light in an x-y plane within the waveguide, and at least one light extraction feature for extracting light out of the waveguide in an illumination pattern comprising at least one of the x- and y-extents that is offset with respect to the x- and y-dimensions, respectively. Additionally, the optical waveguide comprises optical features on at least first, second, and third sides thereof.
