Abstract:
1. A lighted computer keyboard comprising: a keyboard housing; a plurality of key members constructed of a substantially hard non-deformable material, said key members being depressably positioned within said keyboard housing; a substantially translucent elastic diaphragm underlying said key members for biasing said key members in an upward direction; a circuit board underlying said plurality of key members and said elastic diaphragm, said circuit board being operational to produce signals in response to depression of said key members; and a luminescent planar sheet for producing light, said luminescent planar sheet underlying said key members and said elastic diaphragm, and being positioned between said elastic diaphragm and said circuit board, said luminescent planar sheet being optically connected to said key members so as to permit the transmission of light to at least some of said plurality of key members.
