As a pioneer in global lighting tools, incandescent lamps are fading out of people's lives and are gradually being replaced by a new generation of lighting tools. The color variety, brightness and power of LEDs have changed dramatically over the past few years. As a new type of high-efficiency solid-state light source, LED has the advantages of small size, energy saving and environmental protection. Therefore, it is widely used in indicators, displays and backlights, and plays an unparalleled role in traditional light sources. However, so far, they have not been able to fully play their role in the home and public lighting field, and silicone is laying the foundation for LED lighting tools to enter thousands of households with its excellent performance.

A light-emitting diode (LED) is a light-emitting display device made of a semiconductor material such as gallium phosphide (Gap) that directly converts electrical energy into light energy. The heart of the LED is a semiconductor wafer that emits light when powered. The light source can be controlled by a condenser lens or a diverging lens, which is usually made of a material such as silicone/silicone, plastic, glass, or the like.

LEDs are widely used in screen display systems, indicator lights, backlights for mobile phones or digital products, etc. because of their easy control, low-voltage DC drive, low energy consumption, high stability, short response time, and multi-color illumination. The application in landscape lighting, interior lighting, car lights, and mining lamps has also been actively developed, but the use of LEDs in functional lighting is still immature. The application of silicone materials in the field of LED production has undoubtedly become an important factor in promoting the development of LED lighting.

1. Silicone materials are widely used in the LED industry, and LED lighting tools will penetrate every corner of people's lives. While providing convenience for life, it will also create endless opportunities for energy conservation and economic development in China and the world. According to Philips' forecast, LED lighting will account for 90% of the total lighting market in 2020, and traditional general lighting will only have a 10% market share.

2. Development status of domestic LED lighting industry China's LED industry developed in the 1970s and maintained a rapid development trend. According to Zibo, director of the Beijing Semiconductor Lighting Technology Promotion Center, as of the end of 2008, there are about 3,000 enterprises in China's LED industry, covering all areas of the upper, middle and lower reaches. The output value of the whole industry is about 70 billion yuan, of which the output value of the chip is 1.9 billion yuan. 18.5 billion yuan. At present, China's LED industry has entered the stage of independent research and development and innovation, forming a relatively complete industrial chain structure and a model of production, education and research integration. In 2009, domestic LED manufacturers were in a critical period. On the one hand, with the global energy crisis and the worsening environmental environment, governments have given great support to the LED technology as the fourth-generation light source. On the other hand, the rapid development of LED technology and the efforts of LED manufacturers have greatly promoted. The rapid development of the LED industry. At present, the most concerned about LED applications at home and abroad, the biggest development prospect is the LED lighting industry.
