Patent Number: 4095139 
Title: Light Control System 
Abstract: A light control system for selectively controlling the light intensity levels of a plurality of light groups, each group including one or more lights, is disclosed. The system comprises a control for generating a parallel binary-coded signal representative of a predetermined current level to be applied to a particular light group; a signal generator for providing (1) a unique and predetermined serially-coded address signal corresponding to the particular light group and, (2) a serially-coded data signal representative of the current level in response to the parallel binary-coded signal, and; a plurality of receivers, at least one for each light group for applying the current level to the particular light group only in response to the address signal and data signal. A common wire bus for transmitting the address and data signals from the signal generator to each of the receivers is utilized to substantially reduce the wiring required.
