Abstract:
A lighted key board with numerous individual key pads, comprising:a) numerous small grain of wheat lights fixedly mounted in translucent plastic mounting blocks positioned adjacent to key pads and with reversed beveled side edges, a photosensitive transistor and electrical circuitry which increases voltage to the lights when ambient light decreases and decreases voltage to the lights when ambient light increases,b) wherein each key pad independently moves when depressed and wherein the key pads are constructed of translucent material with skirted side edges which mate with the reversed beveled side edges of the mounting blocks and are further retained on the key board by the mating of the key pads with the mounting blocks, the key pads further include a reflective back surface coating, movement of the key pads in relation to the mounting blocks provide a means for allowing light to travel from the translucent mounting blocks to the key pads when an individual key pad is not depressed and when an individual key pad is depressed the light does not travel through the mounting block to the key pad, andc) a manual resistor switch in the electrical circuitry that allows a user to alter the voltage supplied to the numerous light so that the light intensity may be manually adjusted.
