The LED driver is usually composed of an input, an output, a control module and a protection module. The input end receives the mains current, and after the transformer depressurizes, it enters the rectifier bridge for rectification filtering, and then the input capacitor filters the current, and finally adjusts the output voltage and current through the switching transformer.
The control module generally uses a microprocessor or integrated circuit chip to control and protect the brightness and current of the LED.
It consists of signal amplifier, register, decoder and tube.
