Wu Ling: Developing Strategic Lighting Emerging Industries is an Important Strategic Choice for China

At the 2010 Shanghai International New Light Source New Energy Lighting Forum, Wu Ling, Secretary General of the National Semiconductor Lighting Engineering R&D and Industry Alliance, said that the development of the semiconductor lighting industry is an important strategic choice for China. Government departments should continue to increase technical research in the field of semiconductor lighting. With the support of industrialization and application promotion, the central and local governments should form a synergy in policies and achieve concentrated development in the industry as soon as possible to promote the healthy and rapid development of the industry.

Semiconductor lighting has an important strategic position

Wu Ling pointed out that semiconductor lighting has a huge market demand, and the energy consumption of the whole life cycle in the three stages of material preparation, product manufacturing and application is lower than that of traditional lighting, which has the great advantage of low resource energy consumption; at the same time, it is an important component of manufacturing industry. In part, semiconductor lighting has strong driving force in the fields of information display, digital home appliances, automobiles, equipment, raw materials, etc. In addition, semiconductor lighting has the characteristics of technology and labor, which creates many employment opportunities and comprehensive benefits. Good feature. Therefore, the development of semiconductor lighting is one of the most realistic choices for China to transform its economic development mode and cultivate new growth points.

At present, the LED light effect is higher than the traditional lighting and display light source, showing better energy-saving effects, such as 70% energy saving for landscape lighting, 50% energy saving for LCD TV backlight, 50% energy saving for road lighting, and comprehensive cost of about 3-5 It can be flat with traditional light sources for over 8 years. In 2015, if China's semiconductor lighting enters the 30% general lighting market, it can save about 100 billion kWh annually, which can contribute about one percentage point per year to the reduction of energy consumption per unit of GDP, and can reduce CO2, SO2, NOx and dust emissions by 150 million tons. It is estimated that in 2020, the electricity consumption for lighting will reach 720 billion kWh. If it enters the 50% lighting market, it can save 340 billion kWh per year (equivalent to the total annual power generation of four Three Gorges power stations). Power station. Therefore, strategic emerging industry semiconductor lighting is also an important way to save energy and protect the environment, develop a low-carbon economy, and achieve sustainable development.

At the same time, semiconductor lighting as a strategic technology is also the key to the development and breakthrough of semiconductor technology in the 21st century. Strategic emerging industry semiconductor lighting will enhance the core competitiveness of China's next-generation information technology, and drive the development of the third generation of wide-bandgap semiconductor technology, which is an important entry point and breakthrough point in the fields of optoelectronics, information, power electronics, and national defense. It has extremely important strategic significance for the development of new generation information technology.

Developing semiconductor lighting is suitable for China's current situation

The strategic emerging industry semiconductor lighting industry has the characteristics of moderate technology and new markets. Based on the foundation of traditional lighting and semiconductor industry, although the upstream core technology has gaps, the backward distance is not very large. China has initially established a semiconductor lighting technology research and development system. At present, there are still many problems to be solved in the basic research of semiconductor lighting materials growth and luminescence mechanism. China and the developed countries in the world are at the same starting line on the next generation of white light technology routes, and have the conditions for leap-forward development. The emerging lighting market with huge potential in China, the corresponding manufacturing technology and considerable production capacity, has strong appeal to foreign companies, and has become the preferred region for international giants to invest and build factories and cooperate in research and development. In addition, semiconductor lighting technology is labor intensive and the investment intensity and risk are much lower than the typical characteristics of microelectronics. China is also a major resource country for semiconductor lighting, and it has an advantage in raw material supply security. These conditions make the development of China's semiconductor lighting industry in the face of a once-in-a-lifetime historical opportunity, and have the foundation and conditions for achieving leap-forward development and becoming one of the top three in the world.

The government should deploy the system from the height of the national strategy

The development of China's semiconductor lighting industry faces both significant historical opportunities and severe challenges. In terms of technology, how to break through the upstream epitaxial materials, key technologies of core devices, change the lack of core patents, and weak R&D and industrialization capabilities. The key equipment of MOCVD relies on imports, and the gap in profitability is very different. In the industry, how to form industrial agglomeration, change the scale of China's enterprises is small and scattered, lack of leading brand enterprises; in the development environment, how to form policy synergy and achieve industrial balance Development is a problem that requires in-depth thinking and efforts by the industry.

In the face of the above problems, it is recommended that the national level should form a joint force. The Ministry of Science and Technology, the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Housing and Urban-Rural Development should continue to increase their support for technical research, industrialization and application promotion in the field of semiconductor lighting. Local planning should The national goals are consistent, and cluster development will be realized as soon as possible in the industry.

During the "Twelfth Five-Year Plan" period, efforts should be made from four aspects. One is to improve the semiconductor lighting industry chain and enhance the competitiveness of the entire industry chain in the international market; the second is to deploy the next generation of white light core technology routes ahead of the strategic high ground; the third is to innovate semiconductor lighting Application, enhance the industrial value chain; Fourth, establish a complete service innovation and product development service chain.
