Embodiment: present embodiment is made up of infrared transmitter and infrared remote receiver.Infrared transmitter is made up of oscillating circuit 1 and driving radiating circuit 9.Oscillating circuit 1 by the time basis set IC4 in blocks, R ₁, R ₂, C ₁, W ₁, D ₁Form.IC4 selects NE555 for use, R ₁, R ₂, C ₁, W ₁Parameter determining frequency of oscillation and duty of ratio.Drive radiating circuit 9 by triode T ₁, infrared-emitting diode D ₂, R ₃, R ₄Button AJ1, dc-battery E form.Though the electric current of NE555 output is bigger, the power utilization rate of its output voltage is low, for this reason by T ₁, R ₃, R ₄Form driver and promote transmitting tube D ₂

Infrared remote receiver is made up of reception amplifying circuit 2, storage memory circuit 3, drive circuit 4, controllable silicon 5, light fixture 6, self-locking remote control switch 7, D.C. regulated power supply 8.Receive amplifying circuit 2 by infrared receiving diode D ₃, frequency-selecting amplifies integrated IC1, R ₅～R ₁₂, C ₂～C ₆, C ₁₀, triode T ₂Form.IC1 selects CX20106 application-specific integrated circuit (ASIC), C for use ₂, C ₅, C ₁₀, R ₇, R ₈Parameter decision select the frequency range of amplifying, T ₂, R ₉～R ₁₂Form inverting amplifier to promote storage memory circuit 3.Storage memory circuit 3 is by trigger IC2, R ₁₄, C ₇Form, IC2 selects CD4013 for use.Drive circuit 4 is by triode T ₃, R ₁₅, R ₁₆, C ₈Form.R ₁₆Meet T ₃Base stage, connect 1 pin of IC2, R then ₁₅Meet T ₃Collector electrode, meet controllable silicon T then ₅The control utmost point.Controllable silicon T ₅Select bidirectional triode thyristor for use, T ₅Anode and negative electrode connect power supply and lamp respectively, i.e. controllable silicon T ₅Be serially connected on the output of self-locking remote control switch after modulator is connected.D ₃The infrared signal that receives is amplified through the IC1 frequency-selecting, exports a low level at 7 pin of IC1, is high level under the 7 pin normalities of IC1, so T ₂Conducting, its collector electrode is a low level, when 7 pin of IC1 during by high level step-down level, T ₂End, so its current collection high level very, this step signal is added to the trigger end of IC2, makes its output Q end become the stable state of high level, pulse of storage memory, and this high level makes T ₃Conducting triggers the controllable silicon conducting to the greatest extent, alternating current path is provided for lamp D, and lamp is lighted.Work as D ₃When receiving a pulse again, amplify through IC1, its 7 pin becomes low level again again, and the trigger end of IC2 comes a step signal again, so its Q end just turns back low level by high level, and keeps stable state, this low level makes T ₃End, just can turn-off at alternating current commutation point place because the SCR control utmost point loses trigger current, lamp D extinguishes.If press the operation keys of reflector repeatedly, just lamp light on and off repeatedly.Self-locking remote control switch 7 is by button AJ2, controllable silicon T ₆, triode T ₄, R ₁₇, R ₁₈, R ₁₃, C ₁₁IC3 forms.T ₆And at the two ends of AJ2, T ₆The control utmost point meet R ₁₈, R ₁₈Another termination T ₄Collector electrode, R ₁₇Meet T ₄Base stage.The input termination driving amplifier T of NAND gate IC3 ₃Collector electrode, another input is through R ₁₃Connect the trigger end of trigger IC2, the output termination R of IC3 ₁₇The other end.The receiver power supply is started working when pressing AJ2.Because 7 pin of normality IC1 are high level, so T ₂Conducting, its collector electrode is a low level, so the output of IC3 is exactly high level, makes T ₄Conducting triggers T to the greatest extent ₆, make AJ2 self-locking short circuit, though the receiver of AJ2 disconnection after this still is powered.When needs cut off the power supply of receiver, the sustainable operation keys of pressing reflector, reflector promptly sends continuous long burst, and receiver makes T after receiving and amplifying ₂Collector electrode continues high level, and passes through R ₁₃To C ₁₁Charging makes 1 pin of IC3 reach high level.When lamp extinguishes, T ₃Collector electrode must be high level, so 2 pin of IC3 also are high level, its output 6 has also just become low level, makes T ₄End.T ₆Turn-off owing to having lost trigger current, so entire circuit is cut off the electricity supply.Because R ₁₃, C ₁₁Have long time constant, when the open and close lamp, T ₂The short time saltus step of collector electrode becomes high level, and deficiency is so that C ₁₁Be charged to the on-level of IC3, so IC3 has only the T of working as ₃Collector electrode high level (being that lamp extinguishes), T ₂When collector electrode continued high level, 6 pin of IC3 are output low level, T ₆Just turn-off.
