The operation principle of acousto-optic automatic control delayed lamp is: voice signal is by microphone MIC pickup, amplifier A through LM324 amplifies, obtain an AC signal, AC signal is by partiting dc capacitor C3 then, obtains an AC signal that does not contain the direct current composition, passes through current rectifying and wave filtering circuit again, be transformed into d. c. voltage signal, in above-mentioned audio frequency amplifies and shaping circuit is arranged side by side light-operated circuit, the operational amplifier B of LM324 is a voltage comparator, and the negative input end of B is a benchmark voltage.When light, the resistance of photo resistance GR is very little, and more much smaller than W1, then GR and W1 are very high to the positive input terminal partial pressure value of B, and near supply voltage, the positive input terminal of B is higher than the negative input end level like this, comparator B output high level then, otherwise comparator B output low level then.Be added on the comparator C anode input of LM324 by diode D3 when the output high level of comparator B, divider resistance R9 and W2 are inoperative, comparator C output high level, in the time of a little less than night or light, the low level of comparator B output is near no-voltage, and this moment, diode D3 ended, the positive input terminal level of comparator C is decided by R9 and W2 dividing potential drop, when the audio frequency shaping voltage of the negative input end of C is higher than positive input terminal voltage, C output low level, otherwise output high level.Here the partial pressure value of the bleeder circuit formed of R9 and W2 is decided by the value of W2, by regulating W2, and the just audio frequency shaping level of may command negative input end, that is can adjust sound controling sensitivity.When comparator C output high level, isolating diode D4 ends, and delay capacitor C6 is charged to supply voltage by R10, is attempted by the negative input end of LM324 monostable circuit D, and the positive input terminal of D obtains 1/2 supply voltage by the R11R12 dividing potential drop.Therefore, negative input end voltage is higher than positive input terminal voltage, monostable circuit D output low level, when darkness and when sound is arranged, the comparator C output low level, delay capacitor C6 is by diode D4 discharge, and C6 voltage becomes OV, then the positive input terminal voltage of monostable circuit D is higher than negative input end voltage, and D exports high level.If at this moment sound disappears, comparator C output high level, diode D4 ends, and C6 stops discharge, and by the R10 charging, after about 30 seconds, C6 voltage is charged to and is higher than 1/2 supply voltage, and then the temporary stable state of D finishes output low level.Thereby the result who produces is: when light, the D output low level can not trigger controllable silicon, and lamp is not lighted, and when darkness and when sound is arranged, D export high level, the triggering controllable silicon, and lamp is lighted, and extinguishes automatically through about 30 seconds.
