| Title: |
Plural Channel Light Dimming System |
| Abstract: |
A remote controlled lighting system in which a foot switch assembly
operates through a logic network to selectively energize intensity and
delay controls in the form of resistance networks controlling the
energization of a capacitor which with an output voltage from a ramp
generator providing pulsed signals corresponding to an alternating current
supply will control operation of a triac connecting the lights to the
alternating current supply for proportionate periods of time in each
alternating half cycle of the alternating current supply. The circuit
includes provisions for delaying the changing in energization levels in a
shift from one desired level to a level of energization through switching
and further includes a master kill switch to de-energize all controls.
