Lamp system take control dimming circuit

DETAILED DESCRIPTION A preferred embodiment of the invention comprises equipping each take control station with a gated semiconductor device connected to a constant current generator.
A variable electronic resistor connected to the device establishes the intensity control to a common dimming network, the gate control to the device determining the operation of the device.
A rate control having a time constant network is connected through a semiconductor to the electronic resistor.
The setting of a resistor in this time constant network determines the rate of intensity change each time the variable electronic resistor is changed to change the intensity.

device is used at each take control station to show when that station is operating.
Switching means is included at the take control stations and in a common interface network to ensure that all other stations except the one in charge are disconnected.
This interface network also includes an electronic capacitance multiplier as part of the time constant network and various voltage compensating devices to ensure reliable operations.
