Embodiment
Like Fig. 1, the circuit diagram shown in 2, it comprises Electret condenser microphone 1, sound control circuit 2, light-operated circuit 3, delay switch circuit 4, power circuit 5, photo resistance 6, DC light source 7.Described Electret condenser microphone X1 one end links to each other with capacitor C 1 one ends, and the X1 other end links to each other with the emitter of triode Q1, and the other end of C1 links to each other with the base stage of Q1; The collector electrode of Q1 links to each other with resistance R 6 one ends, and the R6 other end links to each other with the collector electrode of triode Q2, the grounded emitter of Q2; The base stage of Q2 links to each other with resistance R 4 one ends, and the R4 other end links to each other with photo resistance RG one end, and the collector electrode of Q2 links to each other with the base stage of triode Q3; The emitter of Q3 links to each other with the base stage of diode D1, and the emitter of D1 links to each other with capacitor C 3 one ends, and the emitter of D1 links to each other with resistance R 7 one ends; The R7 other end links to each other with triode Q4 base stage; The collector electrode of Q4 links to each other with the base stage of triode Q5, and the collector electrode of Q5 links to each other with the grid of FET Q6, and the source electrode of Q6 links to each other with DC power supply B1 one end; The B1 other end links to each other with DC light source L1 one end, and the L1 other end links to each other with the drain electrode of Q6.
On daytime, because photo resistance RG receives illumination, resistance value diminishes; Make triode Q2 become saturation conduction, so low level of the collector electrode of Q2 output, the Q3 base stage obtains becoming after this low level ends; R7 send Q4 with the low level of C3 positive terminal output, Q4 become by and from high level of collector terminal output, Q5 obtains becoming saturation conduction immediately behind the high level; The grid of FET Q6 obtains low level and ends from the Q5 collector terminal of saturation conduction, and dc lighting lamp L1 extinguishes;
At night, photo resistance RG receives less than illumination, and it is big that resistance value becomes; Triode Q2 is become end, if when the sound is arranged, X1 is transformed into audio signal with sound wave; Be coupled through C1, R6 and make the audio frequency secondary to Q1, Q3 and amplify, to the C3 charging, C3's voice-frequency signalling current of amplification slowly discharges the electric charge of the abundance emitter terminal through R7 and Q4 after the D1 detection; Q4 conducting in discharge process slowly, the low level of Q4 collector terminal output is ended Q5, and the Q6 grid obtains high level and conducting from the Q5 collector terminal of ending; Dc lighting lamp L1 lights, and after the sound disappeared, C3 can not get the demodulation current boost charge; Make C3 electric charge minimizing after discharge a period of time, Q4 ends when electric charge is reduced to certain value, and the high level of Q4 collector terminal output makes the Q5 conducting; The Q6 grid obtains low level and ends from the Q5 collector terminal of conducting, and dc lighting lamp L1 extinguishes.The so circulation work repeatedly every day of this circuit, thus reach the requirement of circuit design.
