Abstract

See full text

A light guide is provided for illuminating innumerable constructions, but which is ideally suited for illuminating the keys of a keyboard. The light guide includes a translucent planar plate having a top, a bottom and sides. Further, the light guide includes one or more cavities which project upwardly into the translucent plate from its bottom surface. The cavities are hollow or filled with a translucent material so that the translucent plate and the one or more cavities form translucent interfaces where the cavities interface with the plate. The light guide also includes a reflector which covers the plate bottom and cavity openings.
