How to select a suitable qualified LED driver?

图片
  LED lighting penetrates into everyone's life and becomes more intelligent and exquisite. When designing high quality and outstanding lamps, the design engineer must carefully understand the LED driver because it is the heart of the lamp. In this article, LEADPOWER will describe the most commonly used LED driver concepts and provides a method for selecting a suitable qualified LED driver . 1.What are LED drivers LED drivers, also known as LED power supplies , typically convert AC (AC) to stable DC (DC) output, since light-emitting diodes (LEDs) are a unique component that only accepts DC input. 2. To describe the size of the LED drives External LED driver with an internal LED LED drivers can be built into the lamp (inside), placed on the surface of the lamp, or even on the outside of the lamp (outside). Most low-power indoor lights, especially bulbs, use indoor LED drivers to make cheaper and better-looking products, but external LED drivers are commonly used for do...

How to use LED drivers properly?

  According to the characteristics of the power grid, the requirements of LED characteristics and related LED products, the following points should be taken into account when selecting the LED drive power supply .   According to the LED current and voltage characteristics, it is more ideal to use constant current drive. It can avoid the change of LED forward voltage and cause current changes, while the constant current makes the LED brightness stable. In addition, the LED luminous flux is inversely proportional to the temperature, so the use should minimize the power supply heat and design a good cooling system. Thus reducing the ambient temperature of LED work. In order to ensure the overall life of LED products, the junction temperature of LEDs must be controlled within a certain range, that is, to control the working environment temperature of LED products.   Before installation, confirm whether the rated input voltage of the power supply is within the range ...
