| Title: |
Multiple Scene Lighting Controller |
| Abstract: |
A multiple scene lighting controller for controlling m dimmer units (where
m is greater than 1) includes m circuits, each for controlling the
magnitude and rate of change of magnitude of a voltage signal applied to a
corresponding dimmer unit. The magnitude of the voltage signal generated
by each such circuit is determined by a first signal applied thereto,
while the rate of changing the magnitude is determined either by a second
or third signal. A second signal applied to one such circuit causes the
circuit to change the magnitude of the voltage signal at a controlled rate
while a third signal applied to such circuit causes the circuit to rapidly
change the magnitude of the voltage signal. A first n adjustable devices
are connected to a first one of such circuits for independently applying
the first signal thereto, a second n adjustable devices are connected to a
second one of such circuits for independently applying the first signal
thereto, etc. Connected to each such circuit are n other adjustable
devices for independently applying the second signal to the circuits. By
appropriately setting the adjustable devices and by controlling the
application of current to selected ones of the adjustable devices,
different lighting levels and different rates of achieving such lighting
levels can be provided through the control of the dimmer units by the
circuits.
