| Title: |
Computer Controlled Lighting System with Distributed Processing |
| 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
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.
