Analyze LED general lighting drive technology

Recently, TUV SUD (hereinafter referred to as TUV SUD) was invited to participate in the LED general lighting drive technology seminar. TUV SUD's technical experts have analyzed and explained the test and structure aspects of LED driver products in accordance with the new European Standards EN 61347-1:2008+A1:2011+A2:2013 and EN 61347-2-13:2006.

The LED driving power supply is a power converter that converts the power supply into a specific voltage and current to drive the LED light. It seems to be inconspicuous in the design of the entire lighting product, but it is extremely critical.

As LED lighting has obvious advantages in environmental protection and energy saving, at present, countries are actively promoting LED lighting plans. In 2013, the penetration rate of global LED lighting output increased significantly, which also increased the demand for LED driving power, making the LED driving power enter the stage of rapid development. Market analysts generally expect that the market size of China's LED driver power supply will expand by several billion in the next two years, and it will usher in a certain degree of technological breakthrough, especially in the field of high-power LED drive power, because of the strong LED street light. Demand-driven, it is likely to show a good growth momentum. At present, the LED industry is in a period of growth. With the continuous development of LED lighting technology and the constant entry of enterprises, the LED industry will also develop rapidly. In the next 3-5 years, LED lighting will be a period of rapid growth, LED lighting drive power will also be a huge demand explosion at this stage, the relevant departments statistics only in 2013 China's LED driver power supply reached more than 7 million units, the market size has been Expanded to 1.75 billion.

Facing the development trend of LED lighting products at home and abroad, Mr. Zhao Ligang, technical manager of the lighting product service department of TUV SUD invited guest speakers at the seminar, said: “There is a higher probability of failure of LED lamps than traditional lamps, which also affects the LED industry. The important factor of development lies in the power supply, so solving the main contradiction requires solving the power supply problem, and the quality of the power supply depends on factors such as the material, process, environment, and post-maintenance of the power supply, etc. Drive power is an important link in the development of the LED industry chain. The quality of LED drive power directly restricts the reliability of LED lighting products. Therefore, in today's increasingly prominent status of the LED industry, it is particularly important for LED drive power suppliers to grow and expand their own product quality and brand advantages.

TUV SUD adheres to the service concept of “authority certification and value creation”. With its professional technology and huge global expert resources, TUV SUD pays close attention to the dynamics of the international market, the changing trend of market access regulations and the current challenges and opportunities for LED driver products in China. , To provide a full range of information and one-stop service solutions, and actively assist Chinese manufacturers and exporters in solving technical problems and assist international market clearance.
