Abstract:
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. Light produced by a light source, preferably in the form of one or more LEDs, is transmitted to and through the translucent plate until striking the plate-cavity interfaces where the light is refracted into the cavities' interior or reflected upwardly to the plate's upper surface. After initial refraction into a cavity, the light reflects off the reflector and travels again into the translucent plate until transmitted from the plate's upper surface. Preferably, light guide is positioned within a keyboard housing with the cavities underlying the keys so that light is transmitted from the translucent sheet to the keys.

Claim (Index 10):
The lighted keyboard of  claim 10  wherein said reflector covers said top surface except in places where light is to be emitted.
