The development road of LED drive power supply enterprises

According to the forecast of market research institutions, the revenue scale of LED-driven IC market in 2015 will rise from nearly 2 billion US dollars in 2010 to nearly 3. 5 billion US dollars, with an average compound annual growth rate of 12. The LED driver IC required for LED lighting will be the main growth force in this market. However, when the scale of LED-driven market expands, it may be accompanied by a decline in product prices; In addition, AC- Although LED products reduce the number of required driving ICS or even do not need driving ICs, they will not have a significant impact on the market revenue during the forecast period, and even help accelerate the growth of market penetration rate of LED lighting products, LED driving power supply will have a broad application prospect. However, at the same time, domestic homogeneous competition has also caused enterprises to increase their income and not increase their profits, with the implementation of LED driving power supply officially incorporated into 3C compulsory certification starting in September, will it standardize the current disordered market and alleviate the homogenization? In such a favorable but competitive environment, how should LED power enterprises break through and achieve development? Recently, the reporter interviewed Liao Yuzhu, general manager of Dongguan Lingguan Semiconductor Co. , Ltd. , who is steadily moving forward in the field of LED driving power supply, to understand the current real market situation. Innovative thinking and strict standards are equally important. At present, the domestic market has serious homogeneous competition and similar products are everywhere. The whole industry is in urgent need of innovative vitality, while Lingguan semiconductor can launch different kinds of new power supplies every month. To this end, liao Yuzhu said, first of all, personally speaking, I despise homogeneous competition, and this kind of plagiarism is disrespect for the Labor achievements of others; In terms of industry, this phenomenon is very common in China. The product design is too simple, there is no internal innovation and research, and the technical threshold is low, which leads to the chaos of China's LED market; From the perspective of enterprises, the leader is mainly based on technological innovation, from 0- 300w all products are independent innovation research and development, which is different from the similar products in the market. We have this idea at the stage of design and research. Even for products of the same specification, we must have our own characteristics, and then we will promote the market according to this characteristic, we can get good market feedback, which has accordingly become the driving force for our continuous innovation. Under the background of such a rapidly changing LED technology and market, many of the leading products are old products sold in the 2009 s and are still hot-selling products. The reason is that we have made innovative and differentiated evaluation and improvement at the beginning of the research and development case, and have always followed the principle that products pass safety regulations and EMC is standard. It is the current collar that has many evergreen products. Of course, innovation inevitably requires a certain amount of investment in technology research and development, especially in equipment. The collar is equipped with some new testing equipment, such as infrared imager, lightning surge tester, EMI tester with shielded room, electrostatic generator, etc. , which are all possessed by testing and certification institutions but not by General companies. Although there is a lot of investment in this area, it is equivalent to conducting safety regulations and EMC pre-tests in advance in its own company, which can greatly shorten the time to market after product certification. In addition to product innovation, quality is also a key issue. After all, the quality of LED driving power directly affects the service life of lamps and lanterns. All products have been considered from the design stage. For example, the built-in series of products require the temperature of the working environment to reach 80 degrees. The temperature of all key components must meet its rated limit and leave a certain margin. From the perspective of production control, the raw material supply of the product, as small as the resistance and capacitance, is made of Taiwanese raw materials, and the internal quality control is very strict. The product leaves the factory and passes at least six processes of inspection, will be circulated to end customers. September 1, CNCA-C10- 01:2014 mandatory product certification implementation rules lighting appliances 'implementation, LED drive power officially into the 3C mandatory certification category, which further regulates the current disorder LED market, or reduce the phenomenon of domestic homogeneous competition, but it may also cause enterprises to close down in large quantities. In this regard, Liao Yuzhu gave a popular example. If you always follow the traffic rules and drive, there will be no restraint over time, but for those who often violate the rules, once they are strict, he will be very uncomfortable. This principle is the same for LED power supply enterprises. If enterprises have been producing non-strict and non-standard products, once the national standard strikes, they will become unprepared. Certification is a high threshold for some enterprises with low technical level, and it takes a long time and costs a lot, so some small enterprises in China have saved this step. The collar has been designed and produced according to strict foreign standards, and domestic standards have long been no obstacle for us. Because China's 3C standard is also extended from foreign IEC or TUV certification standards, the difference is not big.
