In the past, no one would have thought that the development of LEDs would be so rapid, and that technology and the market would mature in such a short period of time. LED lighting applications have penetrated into the field of commercial lighting and home lighting, and the pace of replacing traditional lighting has significantly accelerated. At the same time, what comes with it is that the quality of the market products is mixed and mixed. A recent news leaked China's face: On August 29, 2014, the European Commission's Non-Food Rapid Alert System (RAPEX) issued a consumer warning on Chinese-made LED power supplies. The notified country in this case is Finland. The name of the LED power supply is WaterproofLEDPowerSupply. The power supply is packaged in a white carton. The electrical detailed parameters are: input voltage: 110-260V, 50 Hz, 0.37~0.26A; output voltage: 12V, 3.7A, 45W, lkI, IP67. The model/model number is 12V45WIP67/LNM-45, and the OECD Portal Category (OECDPortalCategory) is 78000000 (electrical). The insulation performance of the LED power supply is unacceptable, and the creepage distance between the primary and secondary windings is insufficient. As a result, the user may receive an electric shock during use. At the same time, the product does not meet the requirements of the EU Low Voltage Directive and the relevant European standard EN61347. Of course, China has also been working hard to improve product quality, just before the country began to push the 3C certification of LED power. The China National Certification and Accreditation Administration issued the "Notice of the National Certification and Accreditation Administration on the Implementation of the Compulsory Product Certification Implementation Rules", officially promulgating the results of the implementation of the specific product compulsory certification implementation rules. One of them is to increase the electronic ballast for high-intensity gas discharge lamps and the DC or AC electronic control device for LED modules under the category of ballasts for lighting appliances. The LED driver is officially incorporated into the 3C compulsory certification system. Since September 1, 2015, the newly added products may not be manufactured, sold, imported or used in other business activities without certification. We welcome both hands. LED driver power supply has been included in the non-mandatory certification (CQC) system. The 3C certification is only for LED lamps. That is to say, 3C certification is only for testing lamps and there is no separate test power supply. Xu Yingchun, director of Infinity's R&D, said that whether it is a CQC form of voluntary certification or a 3C form of compulsory certification, the introduction of national standards is of great help in regulating the attributes of LED power products and promoting the healthy development of the industry. To a certain extent, it will also improve the technical level of the entire industry, which is a good thing. On the other hand, I feel that this measure has raised the threshold for market access and brought certain opportunities for the development of LED power suppliers with strong domestic strength. The national standard is of course good, we welcome both hands. It will play a very positive role in the black sheep of the sweeping industry. Zhou Bright, general manager of Shenzhen Keli, said. Upgrading LED power supplies 3C mandatory certification is very helpful in improving the technical indicators of the entire industry and regulating the entire market. In the past, LED power supplies were all non-mandatory certifications. Now, after upgrading to compulsory certification, unlicensed products will not be available for distribution, forcing SMEs to work hard to improve these technical indicators. Chen Hao, the product manager of Maoshuo Power, said. Dr. Liu Zongyuan, deputy general manager of Guoxing Photoelectric Lighting Division, also said that the LED driver power supply will be included in the mandatory 3C certification system, which is undoubtedly a positive contribution to the development of LED. Because of the LED power supply, there are targeted standards and regulations to constrain the power supply, so that the power supply factory must operate in accordance with relevant regulations, avoiding all kinds of chaos in the power supply industry, and unifying the safety between the power supply products. Performance indicator requirements. For the lighting companies, due to the 3C certification, the products of each power supply factory will be relatively more standardized than before, which improves the safety and reliability of the power supply, and naturally ensures the overall reliability of the lamps, and also ensures the customers are using them. Security in the process. In the era of non-mandatory certification of LED power, although there are certification terms but they are ineffective, the industry is not very concerned. In particular, some low-end positioning workshop manufacturers in Zhongshan are more concerned about how to sell products, while export-oriented enterprises are more concerned about exporting local certification standards. However, the procurement of some large manufacturers still has certain requirements in the era of CQC certification of LED power supply. Dr. Liu Zongyuan told reporters that their lamps will be CQC certified before, in terms of safety and electromagnetic compatibility, ROHS, reliability, weather resistance, etc. Good power products that are all done now must be 3C certified products. LED has developed to the present stage, and end consumers have already had a certain understanding of LED. Many ordinary people will consciously choose 3C certified products when purchasing LED lamps, and will choose 3C certified power lamps in the future. At present, LED power supplies in most countries are subject to compulsory certification, such as CE in Europe, diamond PSE in Japan, and KC in Korea. The higher the requirements of the developed countries for safety regulations, the stronger the safety awareness of the end consumers. Basically, all safety standards in the world are directly adopted or equivalent to the IEC international standards. In some cases, appropriate adjustments may be made in consideration of national conditions in some places. North American UL certification has always been self-contained, but its starting point in terms of safety performance is also to consider the safety of users, so the content of IEC is largely overlapping. Even some very backward places such as Africa do not have the energy to promote and implement at the national level, but they also adopt IEC certification indicators in terms of market access. Don't be lucky. It is reasonable to say that standards should be ahead of the market, but LED development is too rapid. Many of the published standards do not work well for LED development. Most of these standards are in traditional switching power supplies, industrial power supplies or electronic ballasts. References and modifications are made on the basis of the standards of products such as devices, and there is no uniform standard for LED driver power sources, resulting in a variety of LED drivers, and the development resources are not effectively utilized, and the product quality may not be optimally guaranteed. The point of concern of 3C certification is whether it will cause harm to the human body, so there is no certain impact on the variety of LED power supply models. Chen Hao said. Xu Yingchun said that he hopes that the standards released this time can meet the characteristics of LED power supply, to better regulate product attributes and promote healthy and healthy development of the industry. When the EU issued new regulations, the domestic manufacturers all complained, and they all said that the cost of certification fees has reduced overseas competitiveness, and the standards are too high to reach. It is understood that the current price of power supply through 3C certification is about 30,000-50,000 yuan, and an annual inspection fee of several thousand yuan is required. The certification time is about 3 months. For a large number of companies, even if the cost of 50,000 is quickly digested in each product, companies with small shipments will need a certain amount of time to digest the cost, but the overall will not bring too much Impact. Our LED power product standards have always been above CQC certification, and I am not worried about technology. Li Shaoke, deputy general manager of Shenzhen Laifu, said that Leifford is currently studying the 3C certification standard for LED power supply and found that it is similar to the previous CQC certification. There is no big problem for technology companies. From the time point of view, the implementation of the 3C certification is September 1, 2015, and it is more than one year away. At the beginning, there may be a period of adaptation to obtain the 3C certification. However, the series of CQC certifications obtained by Infinet LED Power Supply has more models than the full model, which lays a solid foundation for obtaining new 3C certification. Xu Yingchun said. However, the fortunes of the new EU standard have also been shown in this 3C certification. Everyone is holding on to the drag and wait until time. It will be implemented only next year, and it is estimated that the initial inspection is not very strict. The General Administration of Quality Supervision, Inspection and Quarantine should sample so many products, pumping LEDs, and when to pump them to see their manpower deployment and attention to LEDs. A LED power company CEO told reporters. Chen Hao said that the sampling frequency of 3C certification is actually very high. Many lamps have special acceptance and 3C certification acceptance and factory appendix clauses. The appendix clearly stipulates that 100 inspections must be carried out. The inspection institutions and some sampling inspection units will also strictly enforce them. Dr. Liu Zongyuan said that since the first 3C certification of downlights in 2011, it has received several national, provincial or local supervision and spot checks every year. In recent years, there have been more frequent increases. This year, we have received 4 quality inspections of local and national countries, so there is no chance of luck.
