Abstract
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 bidirectional data link. A communication system provides for the exchange of information between the lamps and the console control system, permitting the console controller to selectively and coordinately test and control the individual lamps. To this end, each of the lamp units includes a microprocessor and a memory where lighting cues may be stored for recall and execution. Control programs for driving each of the lamp parameters are also stored in the memory as are various routines for initializing, testing and diagnosing the lamps. The console includes a microprocessor as well as memory. Commands entered at the console to change the lighting effect produce signals broadcast to all of the lamp units, each of which responds individually and independently to change the light parameters based upon its own operating programs and current state. Programs in the console controller provide for lamp polling and the execution of comprehensive testing regimes to insure a trouble free performance.
