Working principle is as follows:
The end L and N-terminal are connected on 220V power supply first, connect 220V voltage after, 220V voltage by capacitor C1 decompression,
By the bridge rectifier output ripple voltage that D1-D4 is formed, output DC voltage divides two-way after capacitor C2 filtering, and one
Road DC voltage is connected to the anode to be shone by 7 concatenated LED1 of LED light tube；Another way voltage is through the decompression of R1 resistance, VD1
12V voltage is exported after voltage-stabiliser tube pressure stabilizing, C3 capacitor filtering to power to audio-switch control circuit.
Under static standby mode:
The input of MK1 Electret condenser microphone no signal, triode Q1 is in static magnifying state, because resistance R3 resistance value is very big,
There are also because the blocking of capacitor C5 acts on, Q2 triode no-voltage and in by state, Q2 transistor emitter no-voltage is defeated
Q3 triode send as an envoy to by Q4 triode is also at by state, and the concatenated LED light of LED1-LED7 is because no-voltage is without shining.
When extraneous intensity of illumination is enough, VR1 photo resistance is in low impedance state, even if short circuit C5 capacitor, Q2 triode
Base stage also cannot get enough conducting voltages, at this point, Q3, Q4 triode are still in by state, LED light does not work still.
When extraneous intensity of illumination is weaker and noiseless sound signal:
VR1 photo resistance is in high impedance status, compared with the resistance value of R6 resistance, can be considered that VR1 is open-circuit condition, but because
The blocking of C4 capacitor acts on, and Q2 transistor base no-voltage causes Q3 triode still by C7 capacitor still in by state
Still no-voltage, Q4 triode do not work still still in the LED light by state, LED1-LED7 composition yet.
When extraneous intensity of illumination is weaker and by voice signal:
VR1 photo resistance is in high impedance status, and may be regarded as VR1 compared with R6 resistance is open-circuit condition, MK1 Electret condenser microphone
Output audio signal is capacitively coupled to Q1 triode through C4, and it is high in its collector to produce amplitude after the amplification of Q1 triode
Audio signal is by C5 capacitive coupling, through D5 and D6 diode halfwave rectifier, after C6 capacitor filtering output DC voltage through R5 and
The base stage that Q2 triode is arrived after R6 electric resistance partial pressure makes Q2 triode ON, and Q2 transistor collector exports 12V voltage, through D7 bis-
Charge after pole pipe conducting to capacitor C7, due to audio signal frequency will not very high and voice signal have certain lasting when
Between, C7 capacitor can be during this period of time fully charged, and make Q3 triode ON, and Q4 triode ON forms LED1-LED7
LED light obtain electroluminescence.And capacitor C7 is bigger to emitter discharge time constant by resistance R7 to Q3 transistor base, makes
Q4 triode tends to remain on, until the undertension on C7 so that Q3 triode ON, Q4 triode is by LED1-
The LED light of LED7 composition does not work, and reaches acoustic control and turns on light, delay is turned off the light, to reach using electricity wisely.
