As a new type of light source, semiconductor lighting has strong competitiveness. The scale of the industry has been continuously expanded, and the market application fields have been continuously expanded, from lighting and display to automobile, medical, and agricultural fields. Recently, the National Development and Reform Commission and the Ministry of Finance and other 13 departments jointly issued the "13th Five-Year Development Plan for Semiconductor Lighting Industry" (hereinafter referred to as "Planning"). The research and innovation of key technologies is the decisive factor in the development of the semiconductor lighting industry. The fiscal policy supports the research on the key technologies of China's semiconductor lighting industry from large to strong, on the one hand, it helps to solve the problem of the dispersion of innovation elements and the lack of innovation ability; on the other hand, it also points the direction for the next step of development. During the Xiamen Summit of the BRICS, the night of Xiamen was gorgeous, and more than 1,400 nightscape projects including buildings, mountains, shorelines and parks were gradually lit up. The theme is Golden Silk Road, and the colorful city lights of Xiamen have left a deep impression on Chinese and foreign guests. Little-known is that these radiant lighting projects use semiconductor lighting equipment. As a new type of light source, semiconductor lighting has strong competitiveness. The scale of the industry has been continuously expanded, and the market application fields have been continuously expanded, from lighting and display to automobile, medical, and agricultural fields. Recently, the 13th Five-Year Development Plan for Semiconductor Lighting Industry (hereinafter referred to as "Planning") jointly issued by the 13 departments of the National Development and Reform Commission and the Ministry of Finance not only summarized the development trend of China's semiconductor lighting, but also proposed that by 2020, The output value of the semiconductor industry has reached 1 trillion yuan, from semiconductor lighting powers to industrial powers, and cultivating more than one billion sales. Experts said that the "Plan" reflects the national will to save energy and reduce emissions, green development, and science and technology. For the semiconductor lighting industry, which is currently in the stage of becoming bigger and stronger, the "Planning" is coming out at the right time. Fiscal policy supports all aspects of industry, education and research in the semiconductor lighting industry and plays a key role in promoting industrial development. "Planning" introduced the semiconductor lighting industry from big to strong National Semiconductor Lighting Engineering Research and Development and Industry Alliance Secretary-General Wu Ling said in an interview, semiconductor lighting is another revolution after the incandescent lamp, fluorescent light source. Semiconductor illumination is a lighting using solid-state light-emitting devices as a light source, including light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs), which have the characteristics of low power consumption, long life, rich colors, vibration resistance, and strong controllability. The small size of the LED makes it easy to design the lighting. In the building and the car, there are many designs that can see the light, and it is more helpful to reflect the beauty of the lighting. Wu Ling told reporters that during the 12th Five-Year Plan period, the application of semiconductor lighting in China's semiconductor lighting, such as signal, landscape, display and backlight, has been basically mature and has been applied on a large scale. At the same time, the application of functional lighting has exploded since 2013. In fact, as early as 2009 and 2013, the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Science and Technology successively issued the "Opinions on the Development of Semiconductor Lighting Energy-Saving Industry" and the "Semiconductor Lighting Energy-Saving Industry Plan", aiming to guide the semiconductor lighting energy-saving industry. Healthy and orderly development. Wu Ling told reporters that with the rapid development of LED lighting technology and the speed of product replacement, China has become a major semiconductor lighting industry. According to her introduction, from 2003 to 2016, the output value of China's semiconductor lighting industry has achieved a breakthrough from 0 yuan to 521.6 billion yuan; the technical level has rapidly increased, and the gap with the international advanced level has further narrowed. During the 13th Five-Year Plan period, China continued to promote and guide the healthy development of the LED lighting industry. The National Development and Reform Commission's Department of Environmental Protection entrusted the National Semiconductor Lighting Engineering R&D and Industry Alliance, and jointly organized the "Planning" with 10 relevant organizations. At present, with the development of technology in China's semiconductor lighting applications, the industry has entered a new stage of development, gradually moving from the alternative lighting market to intelligent, personalized features, on-demand lighting and beyond lighting applications. At this time, no matter in the industry orientation, innovation drive and development environment, we need a more complete top-level design, and we need policies to give the company a wind vane, so that the entire industry can have a common development vision. Wu Ling said. In 2016, innovative applications such as intelligent lighting and beyond lighting have achieved remarkable results. The integration of semiconductor lighting technology with AR (Augmented Reality), VR (Virtual Reality), Internet of Things, Big Data and other technologies has spawned many new application areas. In addition, some emerging market segments have significantly increased their focus, and automotive LEDs, small-pitch LEDs, plant lighting, poultry lighting, ultraviolet (UV) LEDs, and infrared (IR) LEDs have entered the mainstream of the industry. Especially with the gradual maturity of intelligent lighting technology, it will be deeply integrated with semiconductor lighting in the coming period, bringing new and great changes to the global semiconductor lighting industry. Wu Ling concluded that this will bring development opportunities for the semiconductor lighting industry. Funding support to promote the core technology of the semiconductor lighting industry The semiconductor lighting industry has high technology content, and it is in urgent need of financial policy support in production, education and research. The reporter noted that the "Plan" proposed to support the research of semiconductor lighting basics and common key technologies through national science and technology plans (special projects, funds, etc.), accelerate the research and development of key technologies such as materials, device preparation and system integration, and develop OLED lighting material design and device structure. Research on key technologies for industrialization and other common technologies. Through industrial transformation and upgrading funds and industrialization demonstration projects and other channels, vigorously promote the silicon substrate LED technology and product application with independent intellectual property rights. Key technologies such as materials, device preparation and system integration are the weaknesses of domestic LED lighting companies. Only by mastering the core technology can they truly grasp the right to speak. Wu Ling told reporters that the research and innovation of key technologies is the decisive factor to promote the transformation of China's semiconductor lighting industry from large to strong. The fiscal policy supports the research of key technologies, on the one hand, it helps to solve the problem of scattered innovation factors and insufficient innovation ability. On the other hand, it also points the way for the next step of the company's development, especially from the pursuit of light efficiency to the pursuit of light quality and light quality, from expanding production capacity to intelligent manufacturing, from a single lighting product to a transition beyond lighting applications. Since 2009, the Ministry of Finance and Economics and the Department of Education and Culture have jointly awarded financial support to China's semiconductor lighting industry. Without the guidance of fiscal policy guidance, there is no such prosperous situation in the semiconductor industry. The main drafter of the "Planning", the deputy secretary-general of the National Semiconductor Lighting Engineering R&D and Industry Alliance, said that in addition to the financial support provided by the central government, the local government also launched a fund support plan to promote the technological advancement of the semiconductor lighting industry. It is understood that in 2017, local governments continue to intensively implement relevant funding support programs for key and advantageous industrial technologies, and include semiconductor lighting in key support areas. Most of the funds are used for technology research and development, industrialization and related demonstration applications. The support methods include free grants, loan interest subsidies and paid equity investments, preferred stocks, convertible bonds, etc. The amount of funds ranges from several hundred thousand yuan to ten million yuan, of which the maximum amount of single support in Shenzhen reaches 30 million yuan. These financial support programs cover all aspects of the LED industry chain such as epitaxial chip device packaging demonstration application materials and equipment, not only support for technology research and development and industrialization implementation, but also encourage the exploration of business models. Through financial support, semiconductor lighting will be further promoted, whether it is product technology or final industrialization. Yan Jun said. Compared with traditional fluorescent lamps, LED lighting has the advantages of more energy saving, longer service life, higher luminous efficiency and smaller components. This is the main reason why the government has been pushing LED lighting. The Plan proposes to implement energy efficiency leaders to lead the action. Research and develop a comprehensive evaluation system for energy efficiency of semiconductor lighting products with various indicators, and regularly publish a list of energy efficiency front runners. The study will incorporate energy-efficient front-runner products that meet the requirements of the government procurement policy into the government procurement list of energy-saving products, and implement mandatory procurement or priority procurement. Supported projects such as fixed asset investment and central budget investment are preferred for semiconductor lighting energy efficiency leader products. Strengthen the promotion and promotion of energy-efficient front-runner products, and encourage local governments to give policy support to the products of the energy-efficient front-runners. Yan Jun analyzed that the main promotion of the leader's action for the semiconductor lighting industry is to promote LED lighting products with higher energy efficiency and quality, and guide the production enterprises to adopt lower energy consumption production methods based on ensuring that LED lighting products meet the corresponding standards. In the market, the company encourages enterprises to strive for excellence, strengthen technological innovation, promote the continuous improvement of industrial energy efficiency, and further standardize the application market. It has an important role in promoting the transformation and upgrading of the industry and the improvement of the level of intelligent manufacturing.
