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 7):
A lighted keyboard comprising:\n at least twenty-six light transmitting keys members; an at least partially translucent light transmitting plate made of plastic underlying said key members having an upper surface, a lower surface and side surfaces; at least twenty-six light transmitting cavities projecting into said lower surface of said plate, said twenty-six cavities each having an arcuate dome-shaped sidewall so that said cavities are hemispherical or hemi-ellipsoid in shape, the interface between said plate and said at least twenty-six cavities defining at least twenty-six plate-cavity interfaces; a reflector covering at least a portion of said plate's lower surface and said at least twenty-six cavities; and a light source for communicating light through said plate; said interfaces being at least partially translucent for allowing light transmitted through said plate to refract through said interfaces into cavities, and said cavities being at least partially translucent to permit light refracted into said cavities to reflect off said reflector to again refract through said interfaces to travel upwardly through said plate to transmit light from said plate's upper surface to illuminate said key members.
