This paper introduces the development history of lighting power-saving controller in China, introduces the current status, technology, product characteristics and industry dilemma of lighting power-saving controllers in China, and looks forward to and calls for the ideal concepts, models and technical specifications of future lighting power-saving control products. Realization, and finally put forward the solution of Mani smart inductor technology, hoping to provide reference for the development of power saver technology and market specifications. Key words power-saving lighting energy-saving lighting dimming one, China's lighting power-saving industry history and review China's early lighting power-saving products originated in the early 90s, mainly to learn from and imitation of the United States, Japan's thyristor SCR phase control technology production. In the mid-1990s, the power electronics technology, software control technology, and phase-shifting trigger control theory represented by SCR were rapidly developed, which led to the development of dynamic energy saving of motors, soft start protection of motors, and energy-saving protection equipment and technology for lighting. In the south of China's rapid economic development, a number of high-tech energy-saving companies have emerged. Economic development, memories of the process of internationalization, increasing energy, China's "China Green Lighting Project" and related "energy saving" laws, regulations and policies, industrial and commercial enterprises began to recognize "uncontrolled electricity bills" "The importance of cost, so that the power-saving company saw the hope and the way out, continue to invest, research and develop their own energy-saving products, and promote the development of SCR lighting energy-saving control products. After 2001, there were many funds to find a way out, and a company was set up to join the energy-saving industry to make energy-saving move toward industrialization. As with all other industries, the energy-saving industry and power-saving products have also experienced a "chaotic" situation. The inverter industry with uneven technical levels and high thresholds is difficult to return due to huge investment, while some energy-saving products without technical content can make a fortune. There are no technical standards, no standards, no industry self-discipline, all walks of life, various "energy-saving" concepts are commercial hype, a large number of franchise investment, product profiteering, stealing the concept of power saving, saving rate of fraud, temporary "power saving theme" become corrupt money laundering s method. The loss of dealers' joining interests, the low technical content of products is easy to imitate, and the industry profits, which also prompts sales managers and technicians to "set up another mountain" and separate many power-saving companies. In 2002, due to the diversification of lighting sources, the commercialization of road lighting, the use of electronic ballast energy-saving lamps, the use of neon lights, and the power shortage, the local or centralized compensation of magnetic ballasts made the lighting circuit impossible to guarantee absolute No capacitor, thyristor phase shifting burst conduction, can not adapt to even a small amount of capacitive load on the line, so SCR products are in a sales dilemma for a while, manufacturers and dealers can not wait to the capacitor on the street lamp "defected" . Under this circumstance, various energy-saving companies have to re-integrate traditional electromagnetic transformer technology to adapt to the new situation of lighting circuits and market needs. At present, the “provincial motorâ€, “energy-saving coilâ€, “energy-saving reactance†and “power-saving tyrant†in the market are all such technologies. To some extent, it has found a path to develop for lighting energy-saving technologies. In addition to SCR phase control products and electromagnetic transformer products, the market is also popular with a system power saver and various improved versions. It is called simple parallel installation, adapts to all power supply lines, and saves power significantly. In fact, it is a parallel varistor, TVS tube. Components such as capacitors can be absorbed as lightning protection and voltage surges, and there is no power saving. It is also worth mentioning that there are a small number of power-saving companies that like to hang on foreign technologies such as the United States, Japan, Germany, Denmark, New Zealand, Canada, etc., or use advanced foreign operation modes, etc., in fact, dealers and users know It is an authentic domestic company with no external technical background. Considering the so-called mentality of the Chinese people, they all strongly endorse this "Chongyang" approach, which is not conducive to the development and growth of the industry. Learning from and learning from foreign successful technologies and experiences is the basis for the formation of the power-saving industry, but it must be distinguished from misleading and commercial speculation. At present, lighting power saver is not professionally produced by professional companies like inverters. The products produced by Power Saver include all areas of power saving, and the lighting power-saving controller is one of the many power-saving products of the power-saving company. The professional production of lighting power-saving controllers has yet to be specialized in the market and the division of labor in the industry. In the past few years, after the publicity efforts of the state and the “power saverâ€, “environmental protection and energy conservation†has been deeply rooted in the hearts of the people. We are also gratifying to see that through the industry debate, everyone is more and more aware of the nature of power saving, learn to distinguish between commercial traps and false technology, which will be conducive to the healthy development of the power-saving industry. Second, the actual operation of power-saving products government lighting energy-saving projects, due to "financial difficulties", "government image project", "beautification lighting project", "people's heart project", "power shortage", "leading achievements", " Concepts such as “energy conservation and environmental protection†and “green lighting†are intricately conflicted. Even in the two years when the country used electricity, the localities only carefully tested and used it, and there was no large-scale promotion. In addition to not finding a successful “commercial capital operation modelâ€, the main reason is that the country has no clear policy guidance, no satisfactory technical products, no industry technical standards and norms, no successful demonstration projects, and no sufficient leadership decisions. reason. Recently, on July 16, 2004, the Ministry of Construction’s website published the document “Energy Conservation – Urban Green Lighting Demonstration Projectâ€, and clearly promoted lighting and energy saving, and achieved the goal of 15% energy saving in urban lighting by 2008. Strive to achieve the goal of 10% energy saving for indoor lighting in buildings by 2010. "The light is still bright, the light should not be lit up," and detailed lighting specifications are given. This gives local governments the correct direction for urban lighting projects. The spirit of the document will greatly accelerate the development of the lighting energy-saving industry, and enable more funds and talents to invest in lighting energy-saving projects, and promote the development of energy-saving control technology, theoretical research, software technology, telecommunications technology and agreements. Make China's urban lighting energy-saving work as soon as possible on the road of science, health and sustainable development. Urban lighting work is always developing in contradiction. On the one hand, the rapid development of urban economic technology and the continuous improvement of people's living standards, urban lighting has played a significant role in improving the quality of urban human settlements and the image of the city, improving the overall quality of the city, promoting domestic demand, and stimulating the city's nighttime economy. The status of urban construction and people's lives is becoming more and more important, and it has also received high attention from governments at all levels. However, the huge electricity expenses and maintenance costs are also the heavy financial expenditures of local governments. In terms of commercial operation of urban lighting energy-saving funds, some companies are trying to integrate technology, production, capital city government resources, advertising information and other aspects to complement each other. The models currently being explored include third-party contracting methods for street lighting advertising resources, BOT methods, energy contract methods, and third-party funding intervention methods such as banks. Compared with urban lighting energy saving, commercial lighting energy saving work is better. Mainly not due to differences in technology implementation, but the operability of energy-saving product funds. In the implementation of industrial lighting, supermarket lighting, school lighting and other energy-saving, as long as the unit leader or equipment department passed the test, it is considered that the energy-saving technical requirements are met, and the funds are relatively easy to be put in place and cashed. This is an advantage of corporate behavior, and the use of fiscal costs is far more complicated than this. The enthusiasm of commercial lighting users for energy saving is much higher than that of urban lighting. The energy-saving projects for indoor lighting in factories, supermarkets, office buildings, hotels, schools, etc. have increased significantly, and they have become a non-negligible energy-saving city. It is still difficult to achieve, but it will be a strong development trend. It involves a wide range of markets and a huge market. From the perspective of business opportunities and social values, it should be very concerned. Therefore, there is an urgent need for quality supervision, quality inspection departments, and industry certification departments to do a good job of technical and product specifications in advance, and the state administrative departments should make policy guidance to make the industry develop more smoothly and the market more standardized.
