2014 is the 11th year of the National Semiconductor Lighting Project. Adhering to the industrial accumulation of the previous decade, the LED industry is about to enter a period of rapid development. What are the characteristics of the LED lighting market at this critical stage? What other problems need to be solved for LED intelligent lighting? Where will LED companies go? At the 2014 China (Shanghai) International Semiconductor Lighting Application Technology Forum held recently, elites from different fields such as semiconductor lighting, smart home, and smart city gathered together to discuss a new round of competition that was opened by smart lighting. LED lighting to application-driven transformation Faced with a new decade of semiconductor lighting development, application-oriented to enhance industrial value, build an innovation chain, improve the service chain, and enhance the value chain, has become the wind vane of the current LED industry. Yan Jun, executive deputy secretary-general of the National Semiconductor Lighting Engineering R&D and Industry Alliance (CSA), said. At present, semiconductor lighting is facing new opportunities. The incandescent lamp ban is being promoted in many countries around the world. The domestic policy environment is increasingly optimized, and the semiconductor lighting industry will be gradually driven from technology-driven to application-driven. Qi Jun introduced that the localization rate of LED chips in China is increasing year by year, and there is still room for improvement in the future technology; the gap between the technology level of devices and lamps and foreign countries is shrinking; semiconductor lighting technology will be integrated with micro-electric technology and sensing technology to realize lighting. Intelligent and humanized; intelligent lighting terminals will be integrated with technologies such as Internet of Things, cloud computing and mobile Internet, and become an indispensable part of smart homes, smart cities and smart societies. Various information shows that the cross-border era has arrived. In the future, LED will penetrate into the fields of energy, information, life and health, and conduct cross-border cooperation in technology research, standard setting, and demonstration of results, and innovate in cooperation mechanisms. As far as lighting users are concerned, technology is only a means, and lighting effects are the purpose. Wang Shuxiao, a researcher at the China Academy of Building Research, believes that how to ensure the realization of design goals has become the primary task facing the lighting industry in intelligent lighting applications. Early experience in the development of related technologies has shown that many intelligent control systems cannot work as originally designed, which has become an important factor affecting consumer confidence. Lighting debugging is an important guarantee to ensure the performance of the lighting system to achieve the design expectations, so the current priority is to establish lighting system debugging standards. It is foreseeable that more smart devices will emerge in the future, including smart lighting products. Xiong Yuchao, general manager of Haier Smart Home Beijing Innovation Center, is very optimistic about the intelligent lighting industry. He believes that more connected devices will appear, which means more connected services will emerge. In the future, small and beautiful lightweight products will go ahead, and products that need to meet the same emotional needs will break out first. LED lighting is becoming a trend of the times. The next decade will be a decade of simultaneous development and growth of the Internet of Things, smart city construction and semiconductor lighting application technology. Yao Jianwei, a professor at Tianjin University and an academician of the Chinese Academy of Sciences, believes that the business community, universities and the government will be able to explore new ways of building the Internet of Things and industrial development and smart cities. In the future innovation and development, LED lighting can not fall behind in technology, industry and business model. Green lighting is an important part of smart cities. At present, intelligentization has become an important development trend of semiconductor lighting. Therefore, in the process of LED lighting industry transformation, more exploration and experimentation should be done on the innovation mechanism. For the development of semiconductor lighting applications, he gave several suggestions: From a technical point of view, from new materials to new devices, new technologies, new applications still need to continue to promote, do a good job; from an industrial point of view, to unified planning, Strengthen the alliance and innovate the business model to make the LED industry truly bigger and stronger. LEDs are born for intelligent lighting. This is the most prominent feature of LEDs that are different from traditional light sources by Chen Wencheng, senior application technology manager of solid-state lighting Asia-Pacific region of OSRAM Opto Semiconductors China. Chen Wencheng's practical application of LED tunnel lights in the Shanghai Yangtze River Tunnel and Renmin Road Tunnel is an example. In several tunnels in Shanghai where LED lamps were used in the early days, LED tunnel lights produced by different manufacturers have various forms, so the size, luminous flux and light distribution of the lamps Design and power are different, and compatibility interchange cannot be achieved. In addition, the non-standard drive power supply and the self-designed dimming control system not only bring great inconvenience to the maintenance of tunnel lighting, but also affect the enthusiasm of tunnel owners and maintenance units to use LED lighting. In view of these shortcomings, in the subsequent engineering application, the enterprise and the tunnel owner jointly improved, and realized the breakthrough of the light source and the modularization of the light source in the LED LED lighting energy-saving renovation project of Dalian Road Tunnel in Shanghai, and developed the tunnel LED lighting. , the public intelligent control communication protocol LCP-SH protocol. It is gratifying that, under the joint promotion of industry enterprises and tunnel owners, the “Technical Specifications for Tunnel LED Lighting Applicationsâ€, which has been upgraded and improved on the basis of “Shanghai Tunnel LED Lighting Application and Technical Guidance Opinionsâ€, has been approved and approved. For the Shanghai Municipal Engineering Construction Code, it will be implemented on August 1, 2014. This indicates that the LED lighting of Shanghai Tunnel has fully entered the mature and standardized era of light source replacement and intelligent control, filling the gap in the standardization of LED tunnel light interchangeability and intelligent control system among different manufacturers in China, reaching the international leading level. Joint innovation to tighten the industry chain LED lighting development will go through three stages: the first stage is to replace the traditional lighting stage, the second stage is to improve the light efficiency and innovation stage, the third stage is the interconnected lighting era, it will not only serve Lighting this function, but to bring more system services based on lighting. Klaas Vegter, head of research and development at Philips China and senior vice president of Philips China Research Institute, believes that LED lighting needs to pay attention to people's needs in addition to technology, and strive to make people more comfortable and convenient intelligent lighting. At present, connected lighting only occupies a share of the lighting market, and has great potential. Philips will focus on tapping the connected lighting market to enable people to understand high-quality lighting and discover the potential of interconnected lighting and use it to reduce more energy consumption. In fact, as an important attempt for joint innovation, Interconnected Lighting has promoted the technology development, patent strategy, standard testing, quality certification, and quality of the domestic LED lighting industry through the public R&D platform such as SKL-SSL, the national key laboratory for semiconductor joint innovation. Various aspects such as trial incubation have built a complete industrial innovation system for the industry. We should continue to promote joint innovation, promote cross-domain cooperation to promote application innovation, and constantly standardize and improve the application market. Qi Jun believes that to standardize and improve the application market, it is necessary to improve the market supervision system, establish a standard testing and certification system, improve the financial subsidy mechanism, and continue to expand the society's awareness of LED lighting. Guide and encourage enterprises to carry out technological innovation, support market-oriented applications, and cultivate leading brand enterprises with international competitiveness. Intelligent lighting is an indispensable part of the intelligent society. The National Semiconductor Lighting Engineering R&D and Industry Alliance is also organizing the construction of LED lighting systems and control standard systems. Xiao Bian learned from the National Semiconductor Lighting Engineering R&D and Industry Alliance that the alliance has begun to explore third-party standards, testing and certification, promote the standardization of emerging industries with alliance standards, and strengthen product testing and certification.
