Lighting circuit switching and dimmer control system - uses tripping angle controlled gate semiconductor monitored by touch detector

摘要

The lighting circuit switching and dimmer control system includes a power circuit. This power circuit controls the current supply to the load and is connected to an electrical supply source. A power utilisation rate circuit connected to the supply source terminals is also connected to the power circuit and a touch detector circuit. The power circuit is formed by a controlled semiconductor whose electrode is connected to the power utilisation rate circuit. The control circuit for power utilisation rate is a circuit which controls the conduction factor or tripping angle of the controlled semiconductor.
