See full text

A lighting apparatus for providing a substantially uniformly illuminated light emitting surface, the apparatus comprising first and second light sources generating flux patterns including light rays that diverge about first and second central light rays, respectively and a light guide member having substantially straight first and second en sections and a curved section, the first end section having a proximal end and a distal end and formed about a first light axis, the second end section having a proximal end and a distal end and formed about a second light axis, the curved section including first and second ends that are linked to the distal ends of the first and second end sections, respectively, the guide forming a front surface and an oppositely facing textured back surface along each of the end sections and the curved section, the curved section forming a bend such that the back surface is concave and the front surface is convex along the curved section length, at least a portion of the back surface tapered toward the first light axis in the direction from the proximal end to the distal end of the first end section, wherein, the first light source is juxtaposed such that the central light ray is directed along the first light axis and the second light source is juxtaposed such that the central light ray is directed along the second light axis.
