[0002] With the progress of technology and the improvement of people's living standards, LED light belts have become lighting tools in people's lives. LED light belts are generally divided into high-voltage LED light belts and low-voltage LED light belts.

When in use, since the LED lamp beads are all in series and resistors are connected in parallel to divide the voltage, the input voltage range is narrow. When the light belt is long, the LED lamp beads at the back are prone to voltage drop problems, the voltage and current are unstable, the lighting brightness is unstable, and the light decay increases over a long distance, resulting in poor display effects of the light belt, and even power supply supplementation is required, and the use effect for consumers is not good.
