The LED industry is a sunrise industry and a green industry, in line with the direction of scientific development, in line with the intensive and economical development path, in line with the development path of Shenzhen and Shenzhen, and also in line with the country's industrial development direction.
After years of research, it successfully solved the key technical problems of switching power supply, and realized efficient conversion with simple circuit. The current LED driving power supply has very good efficiency, power factor, withstand voltage, current accuracy, stability and life. Strong advantage, ahead of domestic counterparts. In terms of design, the partial pressure method is adopted to effectively reduce the load of each component, and the efficiency is high, which greatly reduces the working temperature rise, thereby improving the life of key components. In terms of materials, the company adopts high-life electrolytic capacitors with independent intellectual property rights, lightning surge protection against high voltage, temperature protection, voltage protection, etc., and is a high-performance LED driving power source with the requirements of aerospace technology.
Introduction to high-life LED power supply
In many power applications, except for purely resistive electrical equipment and some electric motors, almost all electrical equipment is converted into low-voltage direct current.
In the current technology, in many occasions (such as LED lights), a high-frequency switching power supply is used to convert 220V AC into a low-voltage DC power, which is composed of an input filter, a rectifier and a filter, and a switching tube output rectifier and a filter. The working principle is to convert the mains into direct current...
