1. A method of planar illumination comprising the steps of:

  • generating light via a light source;

    directing generated light, defined by a directional component in each of first and second relatively unique axes of a cross-sectional area of an optical conductor, generally perpendicularly to the cross-sectional area such that a component of generated light along the first axis is distributed to a greater extent therealong than a component of generated light along the second axis;

    receiving generated light into a generally planar optical conductor having at least one pair of generally parallel, opposed walls, the light being received at an angle relative to the opposed walls such that a significant portion thereof is reflected between the opposed walls via internal reflection; and

    communicating received light through the optical conductor to a preselected pattern of irregularities associated with the optical conductor to cause light to be emitted outward therefrom.
