The development of technology has spawned new technologies, new economies, and new formats, such as intelligent networks, intelligence, "Internet +", and shared economy, and has also brought many new problems. China is accelerating the implementation of the innovation-driven development strategy. Whether it is education, R&D or industry, it faces enormous development opportunities.
"This year is the first year of China's '13th Five-Year Plan'. With regard to promoting the integration of science and technology and economy and mobilizing the enthusiasm of science and technology, some very good policies have been introduced from the central government to the local government. The semiconductor lighting industry needs to continue in the future. Advance, promote cross-border, innovation, integration, development, continue to open up and embrace change." Cao Jianlin said.
In 2013, China introduced the “Semiconductor Lighting Energy Conservation Industry Planâ€. According to Ren Shuben, as of 2015, the domestic market share of LED lighting products has increased from 20% of the industrial planning to more than 30% now. The output value of the LED lighting industry has reached 560 billion yuan from the industrial planning of 450 billion yuan, exceeding the target of industrial planning. .
As a major consumer of electricity, lighting is an important part of China's energy consumption. “Every year, lighting power consumption is about 13% of the national electricity consumption, and it still keeps rising. The energy-saving technology and management level of China's lighting industry have a certain gap compared with the international advanced level, and the lighting industry improves energy consumption. There is great potential for efficiency and energy saving and emission reduction," Ren Shuben said.
Ren Shuben said that the “Thirteenth Five-Year Plan†is a key period for the development of China's semiconductor lighting industry. The National Development and Reform Commission will focus on promoting top-level design in the future; promoting core technology, high-end product development and industrialization; guiding Chinese LED lighting companies to carry out international capacity cooperation and encouragement. Enterprises introduce new foreign technologies, digest, absorb, innovate and strengthen cross-border integration; encourage enterprises to actively explore foreign markets through various means such as overseas investment and infrastructure construction, and drive domestic LED products and technologies to “go globalâ€. .

The Internet has developed rapidly, and the Internet of Things and intelligent lighting have stood up to the “windowâ€. When the LED is added to the Internet and the Internet of Things, the lighting industry has opened the curtain of intelligent lighting. Zhou Wei, chief technology officer of Huawei Network Technology Co., Ltd., believes that the rapid development of Internet of Things and LED lighting technology has brought about a new era of using IoT to build smart street lighting and building a smart city with street-based IoT. .
"The Internet of Things will explode, and it will reach a market scale of 1.9 trillion yuan in the future. Smart cities are part of the value-for-money mining of the Internet of Things, and 'LED+ Internet of Things' can be the connection point of smart cities." Say.
At present, the global semiconductor lighting industry is in a critical period of mutual development of multiple powers, full of changes, opportunities and challenges. FrankHOHN, vice president of Osram, Germany, said that today's intelligent, Internet of Things affects people's lives, LED is no exception, such as LED in industrial development, AR / VR, wearable devices, smart cities and other applications.
He said that light quality is related to performance, health and happiness. From the user's point of view, it relates to health, performance, biological rhythm and sleep quality; from an environmental point of view, it is related to the balance between demand and energy efficiency; From an industrial perspective, it is about innovation, sustainable development, and high value-added products. "LEDs should eventually achieve multiple wins."
With the advancement of technology, LED lighting is moving from alternative applications to on-demand lighting and beyond lighting. The value of semiconductor lighting products, light quality, and the application of LEDs in health have become the focus. Wen Jia, dean of the Eye Visual Hospital of Wenzhou Medical University, said that lighting is closely related to myopia and visual fatigue. Artificial lighting, the intensity of light, the nature of the spectrum, the time of illumination, the way of illumination, and the location of illumination are all Be serious about research. Lighting is also associated with skin mucosal diseases, neuropsychiatric diseases, and the like. At the same time, lighting is also beneficial, different light can be used to treat different diseases, there are currently light therapy using illumination, such as visible light therapy, ultraviolet therapy, infrared therapy and so on.
“Currently, LED lighting is developing very fast, but there are still many places that need to be studied for the role of health. There are also many challenges, such as the unclear mechanism of lighting on health; lack of a healthy lighting standard system for Chinese and special populations; Lighting products have high homogeneity and lack of innovation. In the future, it is necessary to further study the physiology, pathology and treatment mechanism of illumination for various human systems, and to quantify the health assessment system based on big data."
Semiconductor lighting industry new technology into research and development hot
“High-quality, personalized and multi-form lighting products through on-demand lighting; intelligent hardware, Internet of Things, smart city development through smart lighting; development of lighting and medical, health care, agriculture, communications and other fields through beyond lighting Closely combined, these are all new topics. Chinese companies must seize the opportunity to build their own new brands internationally with new forms and new products, and realize China's move from a lighting manufacturing country to a lighting industry powerhouse." Cao Jianlin said.
Research on nitride materials and equipment has always been the focus of research in the LED industry. The Nobel Prize in Physics, Professor of the University of California, Santa Barbara, Nakamura Shuji believes that the first generation of LEDs is mainly based on SiC and Si; the second generation of LEDs is a gallium nitride substrate; the third generation SSL is laser lighting. He said that sunlight is the best for lighting and light. People can use LEDs to mimic the patterns and methods of sunlight, such as using blue LEDs to synthesize white light, and then adding different wavelengths and compositions of simulated sunlight, such as red light.
As a key technology for semiconductor superlattices, quantum wells, quantum wires, quantum dot structure materials and devices, the future development of MOCVD technology is expected to bring broader prospects for the development of compound semiconductor science and technology and industry. Russell Dupuis, a professor at the Georgia Institute of Technology in the United States, said that the commercial application of MOCVD has many directions. In addition to the LED field, it can also be used in laser diodes, solar cells, photonic integrated circuits, radio frequency and power electronics. In the future, MOCVD will bring changes to the world.
With the vigorous development of the LED lighting industry, in recent years, visible light communication technology for positioning, data transmission, and Internet access (LiFi) through lighting has been increasingly researched by more and more research institutions and enterprises. For the future of visible light communication technology, HaraldHaas, a professor at the University of Edinburgh in the United States, believes that the development of mobile communications requires more powerful technological development.
