The working principle of the automatic clamping light supplementing lamp and the light-operated anti-shake control circuit thereof is described below with reference to fig. 1 and 2:
When the ambient light changes, the impedance characteristic of the photo resistor CDS changes with the light intensity. The stronger the light, the smaller the impedance of the photo resistor CDS, the first resistor R1 and the photo resistor CDS are connected in series to the power source VCC, and divided to the base of the second switch tube Q2, and the base voltage of the second switch tube Q2 is as the following formula (1):
When the ambient illumination decreases, the resistance of the photo resistor CDS rapidly increases, the voltage drop across the first resistor R1 decreases, and V of the second switch tube Q2 decreasesbthe pole voltage rapidly decreases when Vbewhen the saturation on-gate voltage is reached, the E electrode of the second switch tube Q2 is at a low level, the first switch tube Q1 is in saturation on, and the controlled end EN of the enable chip U1 is divided into high levels through the second resistor R2 and the third resistor R3. When the voltage of the controlled end EN is greater than the enabling voltage, the enabling chip U1 is turned on, the output end SW outputs the voltage to the first light-emitting diode LED1 and the second light-emitting diode LED2, and the light supplement lamp is lightened to work.
The controlled terminal EN voltage of the enabling chip U1 is as the following formula (2):
When the ambient illumination rises, the resistance value of the photoresistor CDS rapidly drops, the voltage drop at the two ends of the first resistor R1 rises, and the V of the second switch tube Q2bThe voltage of the electrode rises rapidly when Vbewhen the cut-off gate voltage is reached, the E electrode of the second switch tube Q2 is at a high level, the first switch tube Q1 is cut off, and the controlled end EN of the enable chip U1 is divided into low levels through the second resistor R2 and the third resistor R3. When the voltage of the controlled end EN is smaller than the enabling voltage, the enabling chip U1 is cut off, the output end SW is cut off, the voltage is output, and the light supplement lamp stops working.
When the ambient illumination is low enough to trigger the first output terminal SW voltage output of the enable chip U1 duty cycle, the B electrode of the third switch tube Q3 is in high level saturation conduction, and the fourth resistor R4 and the first resistor R1 form a shunt function in parallel, so that the V of the second switch tube Q2bThe electrode voltage depth is clamped in a low level state, so that the frequent trigger switch action of the enabling chip U1 is avoided when the environmental illumination fluctuates slightly, and at the moment, the V of the second switch tube Q2bthe voltage formula (3) is as follows:
Only when the ambient illuminance rises to V satisfying the formula (3)bewhen the cut-off gate voltage is reached, the E pole of the second switch tube Q2 meets the high level, the first switch tube Q1 is cut off, the controlled end EN of the enabling chip U1 is divided into low levels through the second resistor R2 and the third resistor R3, the enabling chip U1 is cut off, the output end SW is cut off to output voltage, the B pole of the third switch tube Q3 is cut off at the low level, the fourth resistor R4 and the first resistor R1 are not in parallel connection, and deep clamping is released.
