Abstract
PURPOSE:To simplify a transmitter-receiver circuit by using not an FM signal but an even-interval rectangular-wave pulses with a carrier superposed for a control switch unit which exercises remote control over lighting apparatus fitted on a ceiling surface. CONSTITUTION:A transmitter which sends rectangular pulses at even intervals with a carrier superposed consists of power circuit I, oscillation circuit II, control circuit III, amplifier IV, and ceramic speaker SP and through the switching of operation switch 13 provided to circuit II, a time constant is varied to send rectangular pulses, superposed upon the carrier, at even intervals. Then, a receiver which controls lighting apparatus by receiving those rectangular pulses consists of detection circuit VII detecting rectangular pulses, filter circuit VIII detecting those pulses, envelope detection circuit IX which can trigger filter output pulses again, memory circuit X, and control circuit , and circuit VIII detects a fixed pulse to control circuit X, thereby letting lighting apparatus come on or off.
