On November 10, 2009, Ningbo Lighting Industry Association and China Resources Converse Technology (Shanghai) Co., Ltd. held a one-day 2009 "LED Lighting Driver Technology Seminar" at Ningbo Wenchang Hotel. 107 companies from Ningbo, Shanghai, Hangzhou, Wenzhou and other places across the country, nearly 200 LED lighting manufacturers, designers, engineers participated in the seminar.
   The executive vice president, vice president and secretary general of Ningbo Lighting Industry Association attended the seminar. The executive vice president of the association Huang Pengxin and the president of China Resources Weiwei Linghui delivered speeches. Manager of China Lightway LED lighting drive technology, Mr. Yan Chongguang/Senior, explained in detail the various LED lighting drive technologies, analyzed the principles of various application solutions, and introduced a variety of practical drive power solutions that can be directly used in production; Wang Xincheng Manager /High-tech explained in detail the flashing mechanism of LED low-voltage spotlights, and proposed the MR16 solution for the supply of halogen lamp transformers; other engineers also explained the offline LED spotlight solution, and introduced the upcoming new generation for MR16, GU10, E27 LED driver ICs for lighting appliances such as PAR30, PAR38, underwater lights, street lights, tunnel lights, garden lights, etc. At the meeting, the enterprise engineers consulted the experts about the problems that many enterprises had in the relevant technical links. Through the patient's patient answers, the companies all expressed a lot of benefits.
   China Resources Weiwei Technology Co., Ltd. has a wealth of industry experience in the returnees team. The PT series LED lighting driver ICs launched in recent years have been well received by the market. As early as 2005, we began to design and produce LED chip-specific driver chips (ICs). With a wide range of products and a wide range of products, the design solutions have been verified and adopted by customers to meet international and domestic safety standards. Therefore, it has become the first and the world's top five LED driver chip suppliers. Its products and solutions have been widely used in the LED lighting industry and have been recognized by a large number of customers.
   China Resources Converse's low-voltage and high-current output PT4115 can be used in production solutions with only four peripheral components and is widely used. The high-voltage LED lighting driver chip PT4107 has patents for compensating for peak current control. Driven by LED fluorescent lamps; PT4201 is suitable for AC-isolated LED driver applications. In 2010, the PT4211, a step-down high-power LED driver with 350mA output, PT4207 with 100% duty cycle AC/DC high-brightness LED driver will be introduced. It is suitable for AC isolation primary side control of 1-5WLED driver PT4203 for E27 and GU10 lamps. The AC isolation primary side control and MOS external drive PT4204 of PAR20, PAR30 and PAR30 lamps meet the needs of LED lighting.
   At present, the global energy shortage worry has risen again. The LED field in the lighting field has gradually become the main body of human lighting source development with its characteristics of high energy saving, environmental protection, long life, small size and many changes. The Ningbo Lighting Industry Association and China Resources Weiwei Technology Co., Ltd. jointly organized the seminar. Give full play to the role of “bridges, ties, and platforms†in the industry. Through the seminar, the company has a deeper understanding of LED driver technology and enhances the ability of enterprises to overcome the technical problems of driving. At the same time, it can also provide a platform for exchanges and cooperation between industry enterprises.
   The seminar can be described in nine words: “Getting started quickly, less detours, and starting from the high pointâ€, that is, through the experts' explanation of LED driver technology knowledge, the company can quickly find out the problems in the technical links and reduce unnecessary resource waste. And can make their products a higher positioning. The seminar received unanimous praise from the participating companies. The participating companies invited China Resources Converse to visit and cooperate with LED lighting new products.
