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.

35. An optical waveguide, comprising:
-
a first plurality of LED light sources; a second plurality of light coupling features each for transmitting light developed by at least one of the first plurality of LED light sources into the waveguide along a primary light path; a third plurality of light redirection features each for redirecting light in the waveguide to cause at least a portion of the light developed by an LED to be redirected into a secondary light path transverse to the primary light path; and a fourth plurality of light extraction features for directing light in the primary and secondary paths out of the waveguide; wherein at least one of the light redirection features comprises a surface with light scattering features disposed thereon. - View Dependent Claims (36, 37, 49, 50, 51)

38. An optical waveguide comprising x- and y-dimensions, comprising:
-
a first plurality of LED light sources; a second plurality of light coupling features disposed along a width of the waveguide along the x-dimension each for transmitting light developed by at least one of the first plurality of LED light sources into the waveguide along a primary light path directed parallel to the y-dimension wherein the width of the waveguide is bisected by a dividing line; at least one light extraction feature disposed away from the dividing line and comprising a width along the x-dimension for receiving light from at least some of the LED light sources and directing light out of the optical waveguide into a non-central portion of an illumination pattern; and third and fourth pluralities of light redirection features for redirecting light within the waveguide disposed respectively on either side of the dividing line. - View Dependent Claims (39, 40, 41, 52, 53)
