ABSTRACT:
A remotely controlled electrical dimmer circuit (10) for supplying power to an electrical load (18) required power from a constant source comprises a radio signal receiver (14) for receiving a predetermined radio signal from a transmitter (12). The receiver (14) includes a super-generative detector (16) for receiving the predetermined radio signal. An amplifier filter (20) amplifies and filters the signal from the detector (16). A counter (50) triggers a triac (T1) to open and close the circuit (10) in response to a first duration of the predetermined radio signal. The counter (50) also decreases and increases the power supply to the electrical load (18) in a series of stepped levels in response to a second duration of the predetermined radio signal.
