Domestic high-power LED packaging adhesive is inferior to international brands

Semiconductor lighting has been recognized as one of the most promising technology in twenty-first Century, opened the third lighting revolution of the human society, the enormous economic benefits. In the past ten years, the global LED market size of the average annual growth rate of more than 20%; high brightness LED market to grow more rapidly, with an average annual growth rate of 1995-2005 annual rate of 46%, the market size in 2008 reached $5 billion 100 million, accounting for the proportion of LED market increased from 40% in 2001 to 80% in 2008. The conservative estimate of the market in 2012 the scale is expected to reach $11 billion 400 million.

In the LED industry chain, the upper reaches of the LED chip and epitaxial industry, the middle reaches of the LED package, downstream for LED applications. Characteristics of the upstream industry chain: international competition, the most commercial risks, the most scientific and technological content and huge financial support and other characteristics. Upstream LED chip and epitaxial industry is a capital intensive, high technology content, high profit margins, the entire industry has 70% of the profits, the middle reaches of the LED package has 10%-20%, downstream LED applications accounted for 10%-20%.

Although China is the world's largest producer of lighting and lighting, but the main production of low-end products, more than 5 thousand LED manufacturers, accounting for about 18% of the global market share. Most manufacturers only in the field of application of the end of the industry chain, for the remaining less than 30% of the profits, while the whole industry is big, but Europe and other minority upstream companies take this reality, similar to the solar polysilicon industry a few years ago.

In order to meet the requirements of high-power LED packaging, most of the domestic manufacturers in the packaging of high power LED are dependent on imported packaging glue, and rarely use domestic products. However, the high cost of imported packaging glue, resulting in high cost of high power LED packaging on the market, a direct impact on the price of high-power LED. Peer intense price competition, in the case of rising labor costs, some manufacturers said pear big.

I understand that in recent years, Guangdong Hengda new Mstar Technology Ltd that domestic LED manufacturers need, development has been greatly and power LED encapsulation input, developed a series of technical innovation, stable performance, reasonable price of the new high power LED packaging adhesive. Now Kraft special series of products with superior competitive strength, unparalleled cost advantages come out one after another, become a high-power LED packaging manufacturers lucky star.

Indeed, with the development of science and technology and capital investment, domestic manufacturers have been adhering to the development of new technology and new product development, product quality has made great progress, and many products have reached the industry-leading level.

At present there are a lot of people in China's products hold a skeptical attitude, regardless of the use of Chinese products are not as good as foreign products. This "foreign moon is more round than China" is not only not conducive to the formation and maintenance of national brands, but also deeply weakened the enthusiasm of Chinese manufacturers to increase research efforts to upgrade products. Unfortunately, at present, this kind of consumption concept still affects the consumer behavior to some extent. Adhesive industry insiders said that the adhesive industry is also the existence of such unspoken rules".

The reason is the idea of domestic customers to stay in the past ideas, think domestic technology behind the foreign products, but the author visited the Guangdong Hengda new materials science and technology process, a detailed understanding of the production process of high-power LED encapsulation, whether in product development or production of products, are science rigorous. Domestic high-power LED packaging adhesive inferior to international brands, which is an indisputable fact.
