- Sep 30, 2019-

As the world enters the "post-crisis" era, finding and nurturing new economic growth points and developing strategic emerging industries have become the most important means for countries in the world to seize a new round of strategic commanding heights in the new era. For China, the development of strategic emerging industries is not only an expedient measure based on the current and coping with the crisis, but also a major strategic choice for the future and for the long-term. Semiconductor lighting is one of the few strategic emerging industries that have gradually mastered key core technologies, have market demand prospects, and have the characteristics of low resource energy consumption, large driving coefficient, many employment opportunities, and comprehensive benefits. It not only brings a revolution in lighting history after incandescent lamps and fluorescent lamps, but also an important way to save energy and reduce emissions, and will play a more important role in developing a low-carbon economy.


1. Semiconductor lighting has an important contribution to energy conservation, emission reduction and low carbon economy.


At present, LED light efficiency is higher than traditional lighting and display light sources, showing superior energy-saving effects, such as traffic signals, landscape lighting and other special lighting fields, energy-saving effects of more than 80%; compared with traditional lighting, functional lighting For example, LED road lighting can save more than 30% of electricity, tunnel lighting can save 40%, LED indoor downlights, spotlights and other lighting products can replace traditional halogen lamps and fluorescent lamps to save energy by 30%~50%. Since 2009, in " Under the impetus of the “Ten Cities and Ten Thousand Miles” Pilot Demonstration Application Project (hereinafter referred to as “Ten Cities and Ten Thousand Cities”), the speed of domestic technological advancement has obviously accelerated. At present, domestic power LED chips have been applied in some road lighting, indoor downlights and spotlights. Through the integration of optical design, heat dissipation, driving and other technologies, the indoor and outdoor functional lighting fixtures have exceeded 80lm/W. According to the preliminary statistics of 21 pilot cities, as of now, there are more than 500,000 street lamps, tunnel lights and solar LEDs. Street lamps, LED fluorescent lamps, downlights, spotlights, stage lights and other products have been demonstrated and used, saving more than 100 million kWh per year. In addition, driven by the Olympic demonstration project, in addition to the extensive use of LED landscape lighting in the Shanghai World Expo and the Guangzhou Asian Games, some roads and indoor lighting will also demonstrate the application of semiconductor lighting products.


According to estimates, the energy consumption of the LED lamp with a luminous efficacy of 75 lm/W (240 kWh) is much lower than that of incandescent lamps (1505 kWh) and lower than that of compact fluorescent lamps (327 kWh). Low features. At the same time, LEDs do not have fluorescent lamps, energy-saving lamps, and cold cathode tubes (CCFLs) used in existing LCD TVs and LCD backlights. They can greatly reduce the environmental pollution of used lamps, and LED lamps are powered by low-voltage DC. Infrared and ultraviolet radiation are truly green and healthy lighting sources.


In 2009, China's total power generation was 356.06 billion kWh, and lighting power consumption was about 430 billion kWh, accounting for 12% of total electricity consumption, accounting for 5.9% of energy consumption, and growing at a rate of 5% to 10% per year. According to the prediction of Chinese experts, in 2015, the lighting power will reach 600 billion kWh (an annual increase of 3%~5%), the luminous efficacy of LED lamps can reach 120lm/W, and LED lighting accounts for more than 20% of the lighting market. Saving 100 billion kWh of electricity, reducing CO2, SO2, NOx, and dust emissions by 150 million tons, and building 21 units of 1 million kilowatts of power stations, reducing 30% of new power stations (2015 is expected to add 1 million kilowatts of power stations) About 63 seats). It is estimated that in 2020, the lighting power will reach 720 billion kWh, and the luminous efficiency of LED lamps will reach 150lm/W, entering the 50% lighting market, saving 340 billion kWh per year, and building 73 units of 1 million kilowatts of power. Through lighting, we do not need to add new power stations.


Second, China's semiconductor lighting industry has entered a period of rapid development


Since the launch of the semiconductor lighting project in 2003, the Ministry of Science and Technology has supported the technological innovation and industrialization of semiconductor lighting in the field of science and technology research projects and new materials of the 863 program. China's semiconductor lighting industry and technology have made significant progress, initially forming an upstream A relatively complete R&D and industrial system for materials, midstream chip fabrication, downstream device packaging and integrated applications has entered a stage of rapid development.


1. Major breakthroughs in key technologies for industrialization. The LED manufacturing technology based on enterprises is progressing rapidly. The power efficiency of the power chip after the industrialization of the enterprise has reached 80~100lm/W. The power type white LED package has reached the international advanced level. The power-based silicon substrate LED chip with independent intellectual property rights has a luminous efficiency of 78lm/W, which is at the international advanced level.


2. The industry has begun to take shape, the industry chain has become more and more complete, and market applications have been at the forefront of the international market. By the end of 2009, there were more than 3,000 LED companies in China. Among them, there are more than 40 upstream extension and chip manufacturers, about 1,000 mid-stream packaging companies, and 2,000 downstream application products manufacturers. Private enterprises account for 85% of the total number of enterprises. In 2009, China's chip output value increased by 25%, reaching 2.3 billion yuan, basically the same as the growth rate of 26% in 2008. In 2009, the output value of China's LED packaging reached 20.4 billion yuan, up 10% from 18.5 billion yuan in 2008; the output increased by 10% from 9 billion in 2008 to 105.6 billion, of which the output value of high-brightness LED reached 18.6 billion yuan. It accounts for 90% of total LED sales. At the same time, from the perspective of product and enterprise structure, domestic improvement has also been made. SMD and high-power LED packaging have grown rapidly. In 2009, the output value of semiconductor lighting applications in China reached 60 billion yuan. Despite the financial crisis, China's semiconductor lighting industry is still showing a trend of rising against the trend in 2009. The industrial scale has increased to 82.7 billion yuan, an increase of nearly 20%. It is expected to reach 100 billion yuan in 2010.


3. The industrial development environment is becoming more and more perfect. From the launch of the semiconductor lighting project in 2003 by the Ministry of Science and Technology and the launch of the “Ten Cities and Ten Thousand Miles” project in 2009, the recent development and reform commissions and other six ministries and commissions jointly issued guidance on industrial development, and the development of strategic emerging industries proposed by the countries in the post-crisis era. It is actively promoting the development of China's semiconductor lighting industry. Under the guidance and support of government policies, with the improvement of device performance and the realization of energy-saving effects, China's semiconductor lighting industry will enter a period of rapid development, and the market potential is huge, which will drive the industry upgrade. In order to promote technological integration and innovation, accelerate the industrialization of results, and strengthen the cooperation between industry, academia and research, the National Semiconductor Lighting Engineering R&D and Industry Alliance (hereinafter referred to as the Alliance) has established industrial R&D funds, organized major demonstration projects for the Olympic Games, held innovation competitions, coordinated the promotion of standards, and established The patent pool and other work have established a platform for cooperation between industry, academia and research, which has improved the efficiency and level of technological innovation and promoted the implementation of major projects. The alliance standard coordination promotion work has achieved remarkable results. Eight national standards and nine industry standards have been officially released. In order to support the pilot project of “Ten Cities and Ten Thousand Miles”, the Alliance has completed LED road lighting products, tunnel lights, and road and tunnel lighting. Five recommended technical specifications for product supervision and inspection, installation and acceptance implementation rules, technical specifications for cold LED street lighting products, and technical specifications for indoor downlights and spotlights. In addition, the Alliance has already published product inspection data at the United Nations level, providing scientific reference for the local reasonable setting of performance indicators for demonstration applications, and is releasing the recommended products with local energy-saving effects for the next step. The catalogue does the preliminary work. The alliance also researches and formulates national semiconductor lighting patent strategy through technology standardization and standard patenting work, researches and deploys patent network, explores patent pool operation mode, and provides decision support for relevant departments. The work of the Alliance has expanded the vision of domestic semiconductor lighting development, which has aroused great concern from the international community and has had an important impact on the development of domestic industry.


Through the implementation of the national semiconductor lighting project, China's semiconductor lighting industry has established an important position in the international arena, especially the “Ten Cities and Ten Thousand Cities” showcases “Promoting technological innovation through application, leveraging science and technology to support economic development, and promoting energy conservation. The concept of “reduction work” has had a huge and far-reaching impact at home and abroad. In addition, China is a major resource resource for semiconductor lighting, which can guarantee the sustainable development of the industry. The investment intensity and risk of the semiconductor lighting industry is much lower than that of the microelectronics industry. It has the characteristics of double labor-intensive technology, is suitable for China's national conditions, and can drive employment on a large scale.
