An acousto-optic control energy-saving lamp includes a MIC audio input part, an audio amplifier circuit, a voltage doubler rectifier circuit, a DC voltage regulator circuit, a photoresistor, a DC amplifier circuit, and a time delay Control circuit;

The audio signal collected by the MIC audio input part is converted into an electrical signal through an audio amplifier circuit and a voltage doubler rectifier circuit to be input to a DC voltage stabilizing circuit in turn, and the output end of the DC voltage stabilizing circuit is connected to the input end of the DC amplifier circuit through a photoresistor. The output end of the DC amplification circuit is connected with the input end of the delay control circuit, and the output end of the delay control circuit is connected with the light bulb;

After the power supply is connected to the circuit of the acousto-optic control energy-saving lamp, it is divided into two circuits, one of which is input to the delay control circuit, and the other is input to the DC voltage stabilizing circuit.

As a further preferred embodiment of the present invention, the material of the photoresistor is a thyristor. the

This circuit uses household AC 220V as the power supply. After being rectified into direct current, this direct current is provided to the lamp on the one hand. On the other hand, a 6.2V DC working power supply is obtained through voltage division and voltage stabilization. The MIC constitutes a sound input circuit, which is coupled and sent to the audio amplifier circuit. After amplification, the sound signal is converted into direct current through voltage doubling and rectification. The photoresistor has a small resistance value in a bright environment, which is equivalent to a short circuit, and a large resistance value in a dark environment, which is equivalent to an open circuit. Therefore, when the light is on, the sound signal is prevented from continuing to send backwards. The electrical signal input of the light bulb also needs to pass through the DC amplifier circuit and the delay control circuit in turn.

The power consumption of the circuit itself of the utility model is less than 0.5W. It is a non-contact switching element, so it has a long service life. When the light is strong during the day, it plays a role in saving electricity and automatically turns off. At night, it can be turned on by sound.
