Organic silicon technology to promote the upgrading of LED

Silicone technology to promote the rapid growth of the new generation of LED applications. According to the China Epoxy Resin Industry Association (www.epoxy-e.cn) experts, the light emitting diode (LED) since the last century, published in 60s, people have been hoping it can replace the incandescent lamp, halogen lamp, fluorescent lamp, so as to achieve the purpose of saving energy. Organic silicon technology is now playing an important role in the development of a new generation of LED technology and its applications. LED has been widely used in mobile keyboard, large screen TV, and traffic lights and other segments, but so far they have not been able to play a more extensive role in the family, and office lighting. In China this expectation has become more urgent. According to the statistics of the Chinese government, the annual lighting system needs to consume 300 billion kwh of electricity, accounting for about 12% of the total annual electricity consumption. If all such lighting is replaced by LED, will be able to reduce the power consumption by 1/3, thus saving energy equivalent to invest $200 billion, the annual output of the Three Gorges Dam power station. LED has great potential in promoting energy conservation, so from 1996 to promote the use of LED lights, referred to the government's important agenda. Today, China has become the world's most important LED production and packaging base, Shanghai, Dalian, Nanchang, Xiamen and Shenzhen, the 5 cities, the formation of a regional LED industrial clusters. The entire LED industry revenue in 2008, is expected to reach 54 billion yuan high, to 2010 is expected to exceed $100 billion.

LED chip is a kind of compound semiconductor chip, it can be light after power. According to the China Epoxy Resin Industry Association (lens or astigmatic lens to control, the lens 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 optical purity 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, and lens materials, adhesives, sealants and protective coating products. These features allow silicone materials are gradually being applied to a variety of fast-growing high brightness LED market, including: automotive interior lighting, mobile phone flash module, general lighting, as well as the emerging LCD backlight module, etc.. According to the China Association of epoxy resin industry (www.epoxy-e.cn) experts predict that the global market size of high brightness LED, from $4 billion in 2006, up 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 has been significantly improved. It has been proved that organic silicon material has become the key factor to expand the application of HBLED, because of its advantages such as increasing LED, reducing light efficiency and reducing internal heat accumulation.

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. Refers to the organosilicon compounds containing Si-O bond, and at least one organic compound base is directly connected with the silicon atoms, habits are often those with oxygen, sulfur, nitrogen, and organic compounds to make radical silicon atoms connected, as organic silicon compounds. Among them, polysiloxane, which is composed of silicon oxygen bond (-Si-0-Si-), is one of the most studied and most widely used silicone compounds, accounting for more than 90% of the total amount. There are many kinds of products, such as more than 4000 kinds of products, can be divided into raw materials, intermediates, products and products of the top 3 categories. Silicone materials include silicone oil, silicone rubber, silicone resin, the main applications are: varnish, insulating paint, molding compounds, protective coatings, packaging materials, bonding coating, pressure sensitive adhesive, laminated resin, silane coupling agent, etc.. Because of its excellent performance, it has a wide range of applications. It is not only as aviation, cutting-edge technology, the use of special materials and military technology sector, but also for all sectors of the national economy, its application scope has been extended to buildings, electronic and electrical, textile, automobile, machinery, chemical industry, papermaking, leather and metal paint, medical etc.. Silicone can not only be used as a basic material and structural material widely used in some big industry, but also can be used as supplement or auxiliary materials and other materials used, or other materials which improve process performance. The LED field is its new application.
