The rise of LED lighting has played a great role in the market of related plastic accessories. LED lighting accessories such as led lampshade astigmatism plastic profit is relatively high, is one of the important reasons for manufacturers to invest. Many businesses believe that the development of LED lighting is relatively fast, and plastic factories will open molds or process supplied materials according to the needs of the market and develop matching plastic accessories for LED lighting. Semiconductor Lighting has been widely regarded as one of the high-tech fields with development potential due to its advanced technology and extensive use of products. Semiconductor lighting industry has obvious effects of energy saving and environmental protection, and is also considered as a strategic high-tech industry. LED industrialization has experienced a period of recession two years ago. In recent years, China's LED (LED) Breakthroughs have been made in technology and applications have become more and more extensive, especially the official launch of the National Semiconductor Lighting Project, which marks that China's high-brightness LED industry has entered a new stage of accelerated development, it provides a good opportunity for the development of LED industry. Since 2003, domestic cities have suffered from electricity shortages, prompting energy conservation and environmental protection to come to the development agenda of the lighting industry. At the 2004 neon lamp work conference of China Lighting Appliances Association held in Jinan, it was learned that lighting appliances require more environmental protection, energy conservation and light pollution reduction. Green lighting has become a new trend in the development of domestic lighting industry. More than 80 neon companies and lighting brand companies from all over the country participated in the conference. It is worth mentioning that the development of ultra-high brightness and white LED has made great progress. According to the preliminary statistics of the Optoelectronic Devices Branch of China Optical and optoelectronic industry association, the output of LED in China reached 20 billion in 2003, with a growth rate of 5 billion, of which about were ultra-high brightness LED, with a growth rate. China has a huge lighting industry and lighting market. China is now one of the world's largest manufacturers and exporters of lighting appliances. With the support of 863 Plan and other scientific and technological plans, China has initially formed a relatively complete industrial chain from epitaxial wafer production, chip preparation and device packaging integration, at present, there are more than 400 enterprises engaged in the large-scale production of semiconductor LED devices and lighting systems in the country, and packaging has occupied a considerable share in the international market. In terms of decorative lighting, automobile lighting market and traffic lights, LED lighting has great potential. At present, there is no high-power LED on the market, and the high price hinders the development of LED in the lighting field. According to CIR's forecast, the LED market will increase from US $3. 2 billion in 2004 to US $5. 6 billion in 2008, and the market output value of high-brightness light emitting diodes will increase from US $1. 6 billion to 26. US $0. 4 billion, while the ultra-high brightness LED market will grow rapidly from 2006 and account for of the market in 2008. According to the domestic and foreign market demand forecast, the high-speed growth period of China's lighting appliance industry will continue. How to make the future forecast more scientific is the problem we are facing. As a new economic growth point, the Ministry of Information Industry will strive to create a good policy environment for the LED industry, and at the same time promote industrial development in three aspects: encouraging technological innovation, expanding industrial scale, and strengthening application development. The National Semiconductor Lighting team proposed to aim at general lighting in the long run, the short-term goal is to solve the industrialization and low-cost technical problems in the field of special lighting. The Power LED used in semiconductor lighting has a relatively large technological leap with ordinary and super bright LED. While fully affirming the achievements of China's LED industry, we must clearly see that the current key technologies of ultra-high brightness LED need to be mastered. For semiconductor lighting, no matter materials, equipment, chips, packaging technology or application technology have yet achieved a real breakthrough. The industry has not yet formed a scale, and its share in the international market is still very low. The middle and low-end products are mostly, and the high-end products are few. The ability to develop new products needs to be strengthened, the development of LED products with independent intellectual property rights has become a top priority. As far as the domestic market demand is concerned, people's living standards are gradually improving, and the requirements for the quality of living environment are getting higher and higher, putting forward higher requirements for lighting electrical products. The formulation of the new building lighting standard has been completed and will soon be approved for implementation. The new standard is basically in line with international standards and has raised the requirements for lighting in different occasions, it also requires our production enterprises to adapt to the requirements of the new standards and provide corresponding products for various lighting places.
