technical field

Due to the unique advantages of low energy consumption, small size and long life, LED light source is called the fourth generation lighting technology and will become the most important lighting method in the world in the future.

At present, LED light sources are mainly used in the field of low-voltage lighting. Due to the characteristics of low voltage and one-way conduction of LEDs, when using 220V mains to drive LEDs, it is necessary to convert the mains voltage into a DC voltage available for LED light sources, and at the same time control current through the LED. Therefore, currently on the market, LED lamps equipped with LED light sources internally will adopt an internal or external configuration of an independent LED driving power supply to solve the problems of power supply and current control of the internal LED light source.
