COMPUTER CONTROLLED LIGHTING SYSTEM WITH DISTRIBUTED PROCESSING ABSTRACT OF THE DISCLOSURE A stage lighting system has a plurality of automated lamp units which can vary the parameters of a light beam for pan, tilt, brightness, intensity and size. A control console is connected to each of the lamp units via a data link. Each of the lamp units includes a microprocessor and a memory. Control programs for driving each of the lamp parameters are stored in the memory and are executed by the lamp microprocessor. The console includes a microprocessor as well as memory. Commands are input through the console to change the effect produced by the lighting system. Each of these changes is directed to all of the lamp units. Each lamp unit responds individually and independently to change the light parameters based upon its own operating programs and the data condition of the lamp at the time that the change was made. Each of the lamps further stores a unique lamp cue which corresponds to a system cue that is stored in the memory of the console. When a new system cue is selected at the console, this system cue is directed to each of the lamp units which then recall their independent corresponding lamp cues and set the lighting parameters of each individual lamp. The transmission of numbered cues and change conditions substantially reduces the amount of data that must be transmitted.
