Semiconductor lighting is recognized as one of the most promising technologies in the 21st century, opening the third lighting revolution in human society, with enormous economic benefits behind it. In the past ten years, the global LED market has grown at an average annual growth rate of more than 20%; the high-brightness LED market has grown more rapidly, with an average annual growth rate of 46% in 1995-2005 and a market size of US$5.1 billion in 2008. The proportion of the LED market has increased from 40% in 2001 to over 80% in 2008. It is conservatively estimated that the market size in 2012 is expected to reach US$11.4 billion.
In the LED industry chain, upstream is the LED chip and epitaxial industry, the middle reaches for LED packaging, and the downstream for LED applications. Upstream characteristics of the industrial chain: International competition is fierce, the most commercial risks, the most technologically significant and huge financial support. The upstream LED chip and epitaxial industry is a fund-intensive, high-tech, high-profit return, accounting for 70% of the entire industry's profits, midstream LED packaging accounts for 10%-20%, downstream LED applications account for 10%-20%.
Although China is the world's largest producer of lighting sources and lamps, it mainly produces low-end products and more than 5,000 LED manufacturers, accounting for about 18% of the global market. Most manufacturers can only compete for less than 30% of the profits in the application field at the end of the industry chain, but the bulk of the entire industry has been taken away by a few upstream companies such as Europe, the United States and Japan. This reality is similar to the solar polysilicon industry in previous years. .
In order to meet the requirements of high-power LED packaging, most domestic manufacturers rely on imported packaging adhesives when packaging LED high power, and rarely use domestic products. However, the price of imported encapsulant is expensive, which leads to high cost of high-power LED packaging on the market, which directly affects the price of high-power LEDs in China. In the fierce price competition of the peers, in the situation of rising labor costs, some manufacturers said that "a pear" is very large.
The author understands that in recent years, Guangdong Hengda New Materials Technology Co., Ltd. knows the needs of domestic LED manufacturers, has been increasing the investment in research and development of high-power LED packaging adhesives , and developed a series of new high-power technologies with innovative technology, stable performance and reasonable price. LED package adhesive. Now the "Kraft" series of products with superior competitive strength, unparalleled cost advantages have come out one after another, becoming the Fuxing of high-power LED packaging manufacturers.
Indeed, with the development of science and technology and the investment of funds, domestic manufacturers have been insisting on developing new technologies and developing new products. The quality of products has also made great progress, and many products have reached the industry leading level.
At present, there are still many people in China who are suspicious of Chinese products. They indiscriminately believe that the products used in China are not as good as those of foreign products. This narrow concept of "foreign moon is better than China" is not only not conducive to the formation and maintenance of national brands, but also deeply weakens the enthusiasm of Chinese manufacturers to increase scientific research efforts to upgrade products. But unfortunately, the current consumption concept still affects the consumption behavior of many consumers to some extent. Adhesive industry insiders said that the adhesive industry also has such "hidden rules."
The reason is that the domestic customers' ideas are stuck in the past, and they feel that domestic technology lags behind foreign products, but the author has learned about the production process of high-power LED packaging glue in the process of visiting Guangdong Hengda New Materials Technology. Whether it is in the production of products or the research and development of products, it is scientific and rigorous. Domestic high-power LED package adhesive is not inferior to international brands, which is an indisputable fact.
The core of SBH15 transformer produced by FGI is made of amorphous alloy material into a three-phase five-column structure, featuring low temperature rise and low loss. The transformer no-load loss is 30% of the S13 series Oil Filled Transformers. The core of the transformer, the low-voltage coil and the high-voltage coil are very tightly combined and Amorphous Core Transformers have strong short-circuit capability.
