ABSTRACT:
A controlled dimmer lighting system suitable for television studios, remote television pickups and stage lighting employs small, solid state dimmer circuits of the SCR-type on a dimmer per lamp basis. Each dimmer and its associated series-connected lamp is directly connected to a respective power outlet, and a preselected group of the dimmers is controlled in unison by a common time-variable pulse generator for firing the SCRs. The common pulse generator is mounted in a lighting control console, and pulse signals for controlling the dimmers are coupled by miniature coaxial signal cables to the dimmers of the preselected group. The system eliminates the power patch panels and dimmer room required in current studio lighting systems and achieves a simplification in grid outlet wiring, resulting in a significant reduction in size and cost as compared to available studio lighting systems.
