Zusammenfassung:	A light guide includes a first major surface, a second major surface opposed the first major surface, and a light input edge extending between the first and second major surfaces. Micro-optical elements are at the first major surface. The micro-optical elements are embodied as protrusions from or indentations in the major surface. Each micro-optical element includes an end surface and a side surface. The micro-optical elements are configured to output 60 to 90 percent of the light incident thereon through one of the first and the second major surfaces, and are configured to output 10 to 40 percent of the light incident thereon through the other of the first and the second major surfaces.
