| Title: |
Data Distribution in Lighting Systems |
| Abstract: |
A lighting system made up of a plurality of light fixtures which each
produce a light beam, in which each of a plurality of varying devices,
each having an input and an output, and each capable of varying at least
one parameter of the light beam from at least one of the light fixtures,
is responsive to a first value received at the input, where the first
value corresponds to the desired adjustment of a parameter of the light
beam. Each of the varying devices is also capable of generating a second
value which represents status information, and transmitting the second
value via the output. A controller produces the first value and sends it
to an output which is coupled to the input of the varying device. A
monitoring device has an input and is separate from the controller, and
its input is coupled to the output of the varying device.
