The quality of the LED driving power supply directly affects the quality of the LED lighting system, but it is the driving power supply that is relatively easy to damage in the LED lighting system. In order to ensure the safety, efficiency and reliability of the LED drive power supply, strict tests must be carried out during the R&D or production stage.

LED lighting fixtures have the characteristics of higher light efficiency and more environmental protection. LED driving power supply is to convert AC power supply or other DC power supply into constant voltage power supply or constant current power supply available for LED lamps. LED driving power supply is one of the core components of LED lighting lamps.

High-efficiency LED driver are energy-saving products, and the efficiency of the drive power supply should be high. For lamps with such structures as the driving power installed inside, power efficiency is even more important. Because the luminous efficiency of the LED decreases with the increase of the LED temperature, the heat dissipation of the LED is very important. The efficiency of the driving power supply is high, its power consumption is small, and the heat generated in the lamp is small, which reduces the temperature rise of the lamp.
