Apparatus for illuminating keyboards

An appartus adapted to overlie an existing keyboard for illuminating keys on the keyboard comprising:

• A. a thin transparent material having;
• a) a thickness, a top and bottom surface and external edges wherein light rays can pass throughout said thickness,
• b) a plurality of through apertures wherein each said aperture extends through said top and bottom surfaces, and wherein each said aperture being adapted to receive a key on the keyboard when said material is placed over the keyboard such that clearance is provided between the edges of the keys and edges of said through apertures;
• c) said top and bottom surfaces and the external edges of said relatively thin transparent material being treated to prevent light from escaping therefrom,
• d) edges of said through apertures being left clear for permiting light to exit therefrom and into said clearance to illuminate each said keys;
• B. at least one bracket means adapted to removably retain a light source, said bracket means being adapted to be retained on said material to permit light rays emanating from the light source to enter into a portion of said relatively thin transparent material;
• C. a light source adapted to be received into said bracket means and positioned within said material;
• and
• D. coupling means, for coupling a source of electrical power to said light source.
