  • Radio frequency controlled light system
    Patent number: 4355309
    Abstract: A light control system includes a transmitting unit (10) having a receiver unit address (22) and an output address switch (24) for pulse modulating a digitally encoded transmission signal broadcast by a radio frequency oscillator (26). A remotely located receiving unit (28) controls the power supply to an electrical load (42) such as an electrical light in response to digitally encoded data signals transmitted by said transmitting unit (10). The receiving unit (28) includes a radio frequency receiver (32) to apply a signal to digital transmission decoders (34) and a receiver unit address decoder (36). Upon detecting a transmitted signal encoder for said receiving unit (28) an output latch (38) sets an opto-isolated relay circuit (40) to connect or disconnect power to the electrical load (42).
