The main current circuit of a general acousto-optic control switch is mainly controlled by a thyristor BT1, and an incandescent lamp LAMP1 less than 100W is connected in series at the input terminal of 220V mains; After rectification, the rectifier part 1' outputs a pulsating AC switch with zero crossing point to the anode of the thyristor BT1, and the AC switch controls the light and dark of the incandescent lamp LAMP1 by controlling the on-off of the thyristor BT1.

After the sound signal is amplified by the sound control circuit, it is rectified and then triggers the thyristor BT1 to turn on the light. After the delay, the trigger signal is removed, and the SCR BT1 is automatically turned off and the light is off. The thyristor BT1 is usually turned off, and it turns on when the control terminal gets a trigger pulse. After it is turned on, even if the trigger pulse is removed, it still does not turn off. Only a reverse voltage is applied between the anode and the cathode or the output current is cut off. to turn off.

If the acousto-optic control object uses high-brightness white LED lamps instead, and the circuit is not connected to 220V mains power but is powered by a DC power supply, there is no pulsating AC switch output after bridge rectification to control the on-off of the thyristor.

Light control principle:

A. When no light shines on the negative photoresistor R8, the resistance value becomes larger, that is, the partial voltage is large, and the attenuation of the DC control voltage is small, and the electronic switch 3 is turned on to charge the fourth electrolytic capacitor C4 forward. After the charge-discharge circuit 4 delays, the fourth electrolytic capacitor C4 is positively charged and the fourth diode D4 is turned on, the control pole of the thyristor 6 is positively turned on and the LED lamp 7 is turned on.

B. When light shines on the negative photoresistor R8, the resistance becomes smaller, that is, the divided voltage is small, and the DC control voltage is greatly attenuated. The electronic switch 3 is turned off, and the charge on the fourth electrolytic capacitor C4 is discharged through the seventh resistor R7. If the discharge of the fourth electrolytic capacitor C4 is completed after a period of time, the control electrode and the cathode of the thyristor 6 should have the same potential, so that the thyristor 6 is cut off and the small light is off; but the bypass resistance of the fourth electrolytic capacitor C4 is the seventh There is a voltage drop on the resistor R7, and the anode of the fourth diode D4 is not grounded, so the control pole of the thyristor 6 is not cut off, so the LED light 7 is not extinguished.

After the anode of the thyristor 6 is connected in series with the LED lamp 7, it is connected to the output end of the oscillation wave, and the thyristor 6 is turned off by the rectangular wave generated by the oscillation circuit 5.

1. Assuming that the fifth triode VT5 is saturated and turned on, the base of the fifth triode VT5 is connected to the positive pole of the 7.5V power supply through the twelfth and thirteenth resistors R12 and R13, so it will be turned on. The conduction condition is the voltage drop Ube≈0.7V across the base and emitter. After saturated conduction, the voltage drop Uce≈0V across the collector and emitter, and the gap between the collector and emitter is equivalent to a closed switch, then the sixth diode D6 is turned on, and makes the negative pole of the fifth electrolytic capacitor C5 "virtual" land".

2. The current charges the fifth electrolytic capacitor C5 through the eleventh resistor R11. Only when the voltage across the fifth electrolytic capacitor C5 is charged to about 0.7V, the base-emitter of the fourth triode VT4 is forward biased and Immediately, the fifth diode D5 is turned on, and the negative pole of the sixth electrolytic capacitor C6 is "virtual grounded".

3. Before the fourth triode VT4 is saturated and turned on, the sixth electrolytic capacitor C6 is in a reverse charging state, that is, the direction is +7.5V to the fifth diode D5 to the sixth electrolytic capacitor C6 to the fifth triode VT5, The highest reverse charging voltage is 7.5V-0.7V-0.7V=6.1V. After the fourth transistor VT4 is saturated and turned on, the negative pole of the sixth electrolytic capacitor C6 is “virtual grounded” immediately to make the fifth transistor VT5 reverse-biased and turned off. However, the voltage across the sixth electrolytic capacitor C6 cannot change abruptly, and it takes a while to charge the potential of the sixth electrolytic capacitor C6 from -0.7V to about 0.7V to make the fifth transistor VT5 saturated and turned on again.

4. The output waveform of the oscillating circuit is shown in Figure 3, simulating an AC switch with a zero-crossing output pulsation after bridge rectification of the 220V mains. The oscillating AC wave switch controls the on-off of the thyristor 6 to achieve the purpose of controlling the brightness or darkness of the LED lamp 7 .

5. The duty ratio of the oscillating waveform is designed to be adjustable, and the time constant of the charging and discharging circuit 4 is different. The fast charging time is determined by the eleventh resistor R11 and the fifth electrolytic capacitor C5; the slow discharging time is determined by the sum of the resistance values of the twelfth resistor R12 and the thirteenth resistor R13 and the sixth electrolytic capacitor C6; the duty cycle is increased, It is closer to pulsating direct current, but has a zero crossing point, which reduces the flickering of the lamp.

The above embodiments are only for illustrating the utility model, rather than limiting the utility model. Those skilled in the art can also make various transformations or modifications without departing from the spirit and scope of the utility model. Therefore, all equivalent technical solutions should also belong to the category of the present utility model, and should be defined by each claim.
