ABSTRACT:
A keyboard is provided having illuminating keys. The keyboard includes a light channeling membrane and key members constructed at least partially of translucent material so that light produced from a light source is channeled upwardly to the upper surfaces of the key members. The light source may include LED or LEC systems in adjoining relationship to the light channeling membrane or light pipe. In a preferred embodiment, the light source is constructed of a substantially planar illuminescent sheet which underlies the light channeling membrane. In an alternative preferred embodiment, a light pipe is constructed to illuminate light laterally along a portion of its length to illuminate a plurality of key members.
