Silicone technology to promote the rapid growth of the new generation of LED applications

Light emitting diodes (LED) since the advent of the 60s of last century, it has been hoped that it can replace incandescent lamps, halogen lamps and fluorescent lamps, thereby saving energy. Nowadays, silicone technology is playing an important role in opening up a new generation of LED technology and its application market.

"LED has been widely used in many applications, such as cell phone keyboards, large screen televisions, and traffic lights, but so far they have not been able to play a broader role in home and office lighting".

In China, this expectation has become more urgent. According to the Chinese government statistics, the country's annual lighting system consumes 300 billion kwh of electricity, accounting for about 12% of the total annual electricity consumption. If all of these lights are replaced by LED will be able to reduce the power consumption by 1/3, which is equivalent to the energy savings of two hundred billion yuan investment in the construction of the Three Gorges Dam power plant.

LED has great potential in promoting energy conservation, so the promotion of the use of LED lights from 1996 has been mentioned on the agenda of the government. Today, China has become the world's most important LED production and packaging base, Shanghai, Dalian, Nanchang, Xiamen and Shenzhen, the five cities formed a regional LED industrial clusters. The entire LED industry revenue expectations in 2008 reached 54 billion yuan in 2010 is expected to exceed one hundred billion.

LED chip is a kind of compound semiconductor chip, it can be light after power. The light source can be controlled by a condensing lens or a dispersion lens, which is usually made of plastic or epoxy resin. A new generation of high brightness LED (HBLED) lead-free solder, to some extent, can be described as the birth of the environmental regulatory system.

The clarity and thermal stability of silicone materials play an important role in the application of high brightness LED and high reliability. Silicone material is rapidly replacing epoxy resin and other organic materials, for a variety of LED applications to provide a wide range of potting materials, lens materials, adhesives, sealants and protective coating products.

These features allow silicone materials are gradually being applied to a variety of rapidly growing high brightness LED market, including: automotive interior lighting, mobile phone flash module, general lighting and emerging LCD backlight module, etc..

According to industry experts predict that the global high brightness LED market will grow from $4 billion in 2006 to $9 billion in 2011.

With the rapid development of technology, high brightness LED has a wider range of applications, new materials and new processes to improve product performance and reliability. It has been proved that silicone material has become a key driving force for the expansion of HBLED applications by virtue of its advantages in improving LED light efficiency and reducing internal heat accumulation, "BillyHan said. "Silicone is the ideal choice to meet the requirements of LED production, because they can provide excellent reliability, optical clarity, thereby increasing the brightness, so that color is more bright.
