The 19th National Press Center held the fourth collective interview event at the press conference hall on the second floor of the Media Center at 19:00 on October 20th with the theme of “Implementing an Innovation-Driven Development Strategy”. Wang Zhigang, Party Secretary of the Ministry of Science and Technology, Wang Xiujie, Researcher of the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, Wang Endong, Chief Scientist of Inspur Group, Lu Jianjun, Secretary of the Science and Technology Working Committee of Shaanxi Provincial Committee, and Jiang Fengyi, Member of the Standing Committee of Nanchang University, attended and were interviewed.

A reporter asked questions. At present, how is the current situation of LED technology innovation driving the development of semiconductor lighting industry in China? What is the overall competitiveness of China in the international LED industry?

As an expert in the LED field, Jiang Fengyi answered this question. He first popularized the common sense of LED for reporters. LED is a new light source with energy saving and environmental protection. It has high luminous efficiency and is much higher than traditional incandescent lamps and fluorescent lamps, so it is energy-saving.

"China's LED technology and industry have developed rapidly. Both technology and industry have entered the world's advanced ranks," he concluded.

On the one hand, from a technical point of view, the industrial light efficiency of China's white light semiconductors has been level with the world-class level; from the perspective of monochromatic light, the luminous efficiencies of red, orange, yellow, green, cyan, blue and purple light are all Has an international level, in which the yellow LED light effect leads the world;

On the other hand, from an industrial perspective, China is now the largest producer of LEDs and the largest consumer and largest exporter. The scale of production has exceeded 500 billion yuan. China's LED application last year saved nearly 140 billion kWh, reducing carbon dioxide emissions by 120 million tons. The development of LED has made outstanding contributions to energy conservation and emission reduction.

Why is China's LED technology and industry developing so fast? In Jiang Fengyi's view, one is benefiting from the guidance of the state and embodies the advantages of our country's concentrated efforts to do big things.

“The country has formulated an overall strategy in the process of LED technology and industrial development. At the same time, technology tracking and technological innovation are laid out. When the core technology is still not mastered and it is not well mastered, it is mainly based on tracking, but at the same time it also has innovative layout. So now Tracking is also well tracked, there are also independent technologies for innovation, and there are new routes, some of which are leading technologies," he said.

The second is to benefit from the application-driven development strategy. When the core technology is not mastered, we use the core chips and good chips of the people to do the application, and then apply the upstream and midstream chips to the downstream application.

"At the same time, the coordinated work of the central ministries and commissions has also played an important role. The Ministry of Science and Technology, the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Chinese Academy of Sciences, the Ministry of Education, and various local governments have all promoted the development of technology and industry. This is why China's LED can develop so fast. The root cause." Jiang Fengyi said.
