The principle and maintenance of switch power supply for LED light

Hello everybody, this is Wish from Guangzhou KAIHUI Electronics Co., Ltd.,Today I will show you the principle and maintenance of switch power supply for LED light. 

Everytime when it comes to switching power supply and LED light/stage light, we always associate them together. 

As a new type of green light source, LED is bound to be the future development trend in the field of lighting. The most important part，the quality of the switching power supply is connected with the life of the LED lighting products, and so many failures of products are related to the switching power supply, then let's have a look at the working on principle and maintenance of the switching power supply.

The main components of circuit on the LED light switch power supply include: input electromagnetic interference filter, rectification and filtering circuit, power conversion circuit, PWM controller circuit, and output rectification and filtering circuit. 

The auxiliary circuit has an input overvoltage and undervoltage protection circuit, an output undervoltage protection circuit, an output overcurrent protection circuit, an output short circuit protection circuit and etc.

And all our power supplies have short circuit, overload, overvoltage and overcurrent protection in view of this situation. And we provide warranty of two years for all power supplies. Our engineers also will provide on-site maintenance service for you.
