LED lighting industry in China is about to enter the modular era. Modular is the light source, cooling components, power supply synthesis module, mass production, mold making, standardized LED lighting products. Epitaxy, can not bypass the patent barriers to foreign companies, but the module mass production, has a price advantage, and one-time, personalized production costs are much higher. Therefore, the downstream enterprises of LED lighting applications, the modular is a best choice for module notable features: First, the technology is good, and good repair of modular street, now most of the domestic street is a low-power chip inconvenient to repair broken a few, while the modular basically a high-power chips, not easily broken, even the bad also facilitate the repair. Reduction in development costs with fewer inputs to produce high-quality LED lighting products. LED street lamp efficiency is higher than five times the energy-saving lamps, if the module is able to achieve large-scale production, the costs can be reduced to 2 to 3 times. LED lights are more expensive than the price of energy-saving lamps, but the energy savings is much higher than the energy-saving lamps, many companies will choose the LED lamps, a little more money can solve the energy problem, but in the long run, more money. LED technology with each passing day, technology is developing too fast, LED standard very difficult, but in the LED lighting industry, if there is no standard will be like a phone charger, a wide range of LED energy saving lamp manufacturers are not compatible. However, the relevant ministries of the State is still under discussion. In the upper reaches of the epitaxy, chip area, the domestic enterprises over foreign enterprises difficult, but obviously in the downstream advantages, especially in the packaging field, 80 percent of the world's LED lamps in the Chinese package. Is actually the practice of standardization, industrialization modular package, and, through technical innovation, process innovation to reduce costs to achieve the purpose of large-scale manufacturing. Modular is the standardization of end products Lighting project of the Ministry of Science and Technology, the lighting is a strategic industry, the Ministry of Science and subsidies to promote energy efficient lighting. LED strength in the world rankings for the top five, with South Korea and Taiwan, China for the second echelon. Epitaxy, and other upstream areas, Japan, the United States, Germany, in a leading position and formed a patent alliance, domestic chip with foreign chips on the luminous efficiency differential of about 20%, but we have a huge cost advantage. In general, the epitaxial material, chips, auxiliary materials and equipment return on investment period is 10 years, upstream enterprises in the Mainland, such as Xiamen safety, Wuhan Di source, Dalian Road America and so have long-term intention. But for most businesses, they can only be in the package, the application development. Dialectically, the guiding ideology of the Ministry of Science and Technology is to promote the development of applications, packaging applications, features, a short, flat and fast to win. Diversification of LED lamps, radiators, drive power cost more than the chip. Chip sources, either imported from Japan, the United States, Germany, can also be purchased from South Korea, Chinese Taiwan, the chip will not affect the manufacturing cost advantage of the mainland of China. For now, if you standardize, the LED industry in the Mainland than in the United States has an advantage. LED is a very flexible product, standardization is very important, one of the most important is the standardization of end products, namely modular. Aspects of the package, due to the high manufacturing cost of the personalized, if industrial production, good standardization, the entire cost can be reduced by 1/3. Modular can be substantially under the premise of ensuring product quality, reduce costs by modular manufacturing end products usually have a clear price advantage. Some of the traditional lighting companies aware of this, traditional lighting giants like NVC, Op also increased R & D investment, but they want full access to the field of LED lighting, the use of modularity is a shortcut. In general, to achieve low-cost standardized production, the traditional lighting companies need at least 5 to 10 years. At present, the standardization of Chinese enterprises are not doing enough, and Technical Supervision state sector has to play the role of industry standards, and industry organizations made great efforts for the implementation of modular The arrival of technological innovation, will make the entire industry reshuffle, and integration. China's semiconductor lighting gap with foreign countries is 10 years, technology alone is not enough, but also through the capital to integrate, only bigger and can be stronger. Modular to the market first, the twelve enterprises alone is not enough, the most important thing is the whole industry stronger and bigger. Modularity is a breakthrough of new products in China, more than 2,600 enterprises to enter the field of LED, 30 to 40 engage in chip technology, 600 engage the package, 2000 to engage in downstream industries. LED light source, domestic enterprises did not seize the initiative, with a gap of 10 to 20 years with the foreign. The core technology in the short term beyond abroad is not possible, only the concept of innovative technology, the introduction, simulation of advanced technology and capital to move closer to be possible to obtain a comparative advantage. Like China's automobile industry through joint ventures with foreign enterprises, the OEM technical capacity, and thus out of a road. Can a business take-off depends on two factors, one technology, one is marketing, just like the two arms of the boxer, are indispensable. Technical inputs in foreign countries, accounting for 6 percent of overall sales in the country, only 1% to 2% is considered very high. Attention to marketing most businesses because it can increase sales from long-term development, Chinese enterprises need to strengthen technical inputs, although the effective takes time, but to get long-term sustainable growth, technology is a key factor. Is the sole criterion for testing the technology, a mule is a horse, pulled out a walk, Tianjin with 36 LED lights of the pilot testing, only six months, the 1/3 of the street completely does not shine. On yaming bulb factory enterprises of China's first production of incandescent, it spent 10 million yuan to purchase foreign advanced equipment, the equipment for the production of services, but mainly used to measure the temperature of LED modules. Although Yamin bulb factory in the incandescent field is the leader but the LED time has come, opportunity fleeting, and only actively preparing to increase investment, according to their characteristics, such enterprises will have a competitive advantage. The future, the intersection of the disciplines is the breakthrough point of the new products, from this perspective, the light source, cooling parts, the drive power of the three into one "modular manufacturing" will be a breakthrough, but also the right path. Separate government functions from enterprise management The development of LED lighting enterprise, relying on market behavior, government policy to support and guidance. Hangzhou City, the LED lighting industry very seriously. First, the composition of the Municipal Standing Committee, head of the leader of LED lighting the leading group, with 200 million yuan each year to finance new industries, including new materials and new energy, LED lighting is also included. At the same time, we declare the State Ministry of Science and Technology and semiconductor lighting project identified a number of key companies involved in this project; LED lighting industrial base in the Qianjiang Development Zone, both to the enterprise as an entity, must also have a large base as the accumulation of carrier. Hangzhou, the overall development of LED lighting compared with Shenzhen, Dalian, Wuhan, there is a certain distance, but in some ways ahead of other places. For example, the the Zhejiang Maile Si module design and production of similar products in the lead. Their products have been resolved elsewhere, is that the module assembly challenges, including the heat dissipation problem, luminous flux, and the modular design problem. Standard modules to solve production problems, which may be explosive, National Semiconductor light industry bigger and stronger. From the government, to implement the plan of the city of ten thousand light are mainly two types of solar LED lights. From top to bottom has already done the preparation of such a qualification. Products on the market in different ways, several enterprise products to meet market demand, resulting in government procurement has become more cautious, to consider the possibility to achieve road lighting requirements, stability, ability to reach 10,000 hours, this is a matter of public the problem, replace the LED lights, every few days to go wrong, a lot of trouble to repair. All streets are replaced with LED lights, but also a process. Do LED lighting industry, and stronger, this modular model to solve the light problem, as long as the module corresponding terminal can be a wide range of lighting products. Perfect fourth-generation light source is a process Due to lack of standards, blind production, LED lights, the high price, doubt about someone's product, government departments are still hesitant, wait and see. On street lamps, the light source modular to facilitate routine maintenance, do not then the lamps all removed to repair, replace broken light source module can be. With the development of the light source module, and constantly improve the quality, perfect light and color, brightness and prolong life, reduce costs, this is definitely the direction of development. If the price in the short term or can not be resolved, the government may support the development of LED lighting industry, energy contracts management, power supply systems, banking, government, corporate, multi-stakeholder investment, the cost of electricity savings subsidies the price of LED lights the final cost of the subsidies but also to measure the local price. If the price of 1 kWh of electricity is 0.8 yuan, you can use 4 to 5 years to recover costs; if the price of 1 kWh of electricity is 0.5 yuan, you can use the 6 to 7 years to recover the cost. A power issue is not resolved, LED lights require constant current power supply system which requires the constant voltage power supply into the constant current source, the original power output mode to change the power supply system, which will increase certain costs, this part of the cost will be included in the calculation of the total cost. A new light, and gradually improve a process. Module production is not a problem The light source module not only solved the LED heat dissipation problem, and the ingenious design makes the requirements of the chip is reduced, upstream manufacturers supply has become a lot easier. The higher requirements of the chip production process, the waste caused by the higher its energy consumption is quite terrible. LED wafer production technology using metal organic chemical vapor deposition (MOCVD) method, which is under high temperatures and ultrahigh vacuum, a gas into them, and then hydrogen as carrier gas inhalation after mixing sapphire diaphragm on the formation of crystals. The past, LED pay attention to how bright the single, over-emphasis on cutting-edge, into the product of an aristocratic, is not conducive to the promotion. Modular does not require a single how bright it can be combined to bright how bright. This model is one in the future direction of development, because of its significant cost savings. Other enterprises have not yet thought to do the LED lights in this way, but due to the upstream chip MOCVD production equipment, all in the hands of the Americans and the German, while the module uses a new packaging technology, can not find in the foreign and domestic the equipment can be used directly, only the development, improvement of the original equipment or custom equipment. Considerable prospects for LED lighting, LED lighting technology in the United States, no problem, but because of high product prices, the Government has not set aside a lot of money to replace the energy-saving lamps on the market. Currently, the U.S. just in the new project little by little, the introduction of LED lamps, slow progress. At the same time, due to the lack of standards of the LED lighting market, enterprises want to do standard, but they are not enough weight. From this perspective point of view, the U.S. market and Chinese market, are synchronized. The module allows the LED light is more simplistic, rather than become more complex. If all goes well, then, a few months can architecture to build up this way, the North American and South American markets can open up the South American market is to go to follow the U.S.. Module to the U.S. market is a large LED modules "fool" will change the pattern of lighting industry At present, the LED lighting industry, without which a company can solve the problems of mass production, not only domestic enterprises such international giants. Technically speaking, the core problems are focused in the optical, electrical, thermal, from a marketing point of view, the key issue is the market cake did not really take shape. For product development, technology must follow the process from the complex to the simple process; for technology applications, products must be from a professional to fool. The Maile Si found in the development of high power LED lighting products, light, electricity, heat "technology LED products, application modules, is technical simplification, will be applied fool. In this way, the upstream and downstream enterprises of the entire lamp capacity bottleneck immediately broke through. Many companies believe that the investment in LED lighting, slow, if not put the means to exit the market exit can not be reconciled in a dilemma. LED module, LED investment of millions of funds will be leveled and the high threshold, the real emergence of a new pattern of industrialization "As long as you do the lighting, you can do LED's! In this new pattern of industrialization, the cost of LED lighting products will plummet, the market cake to really take shape. Module to solve the light, electricity, heat Standard module must first solve the uniformity problem of LED lights; to solve the brightness problem, that is, the light emitted by the LED lights have a certain strength, however, the luminosity, the stronger the higher the temperature, which is facing a third problem: how to heat? LED light source, heat the better, its junction temperature is lower the longer the life, the higher the efficiency. The fourth difficulty is the power problem. To drive the LED power supply has a generally normal power supply, LEDs require constant current power supply. 2007 to 2008, many cities installed LED lights, but failure is very large, almost 80% of the damage caused by the drive power. All issues are resolved after the introduction of standard modules. Modular solve the problem of light, electricity, heat it outside with the shade of a variety of shapes, and power size can be adjusted, for example, 30W is a unit, if you need 120W, 4 units assembled on the can be achieved. Once the module mass production, is bound to make the LED light prices fell. The key next step is how to make it into a product of the civilian population, to put it down to the middle-income people can accept the level, so as to low-carbon economic upswing to eliminate all incandescent and energy-saving lamps. In 2009, the Ministry of Science and Technology launched the semiconductor light source modular envisaged to solve the problem of the high price of LED lights in large scale. Modularity is a good business model LED is a new concept of solid state light source, its main advantage is the energy-saving lighting in the area showing the prominent energy saving effect, than incandescent bulbs, saving 80% than the mercury lamps, sodium lamps saving 60% or more. Because of its unparalleled energy-saving, environmental protection, longevity, controllability and other technical advantages, as one of the world in recent years the most promising high-tech, officially opened the prelude of a comprehensive alternative to traditional lighting, and semiconductor lighting technology innovation is changing the centuries-old tradition lighting history. Into the era of high energy consumption around the world the focus of attention focused to the LED of this "light on future technologies and the resulting lighting areas of the third revolution. Modularity is a good business development model. In fact, with the accelerated development of the market, LED lighting industry will inevitably be faced with "survival of the fittest" situation. Many businesses are now the focus of competition on the domestic, which is a change in the industrial market. Modular will revolutionize the traditional lighting business model, NVC LED products have been sold in engineering channels. LED as a rapidly developing new technologies, the NVC has been continuing concern. With the LED technology matures, the NVC will quickly develop products that meet customer needs LED as a new lighting technology, its unique light-emitting principle will subvert the way of lighting and lighting products, will further change the traditional lighting industry business model. LED rapid development process, the traditional business model for emerging innovative business models and positive change is bound to each other, in harmony and mutual promotion development. The LED lighting market is a typical technology-driven, mature process technology, new application areas will gradually appear. When the technology is not mature and immature products will damage consumer confidence in new technologies. LED lighting is standardized, the issue of global climate change makes human beings more and more concerned about the Earth's environment, promote the protection of the Earth. For now, the LED is lighting the lowest energy consumption, low emissions, less radiation, a new generation of pollution-free light source, has been slowly replacing the traditional incandescent light bulbs and metal halide. The LED has great prospects for development, but because many manufacturers use inferior products deceive consumers' interests, not a thorough understanding of consumer LED lamps. Now the LED as a newborn, the market is still very unstable. Many manufacturers are aware of the LED has great prospects for development, but because of the immaturity of this technology, leading manufacturers to halt. Everyone knows that the LED has great development potential, investors have a share of the idea, but they are only value that part of the most profitable result, the high price of LED products. This uneven division of labor in the LED components is easy to generate a lot of difference, some people for the money, ignore some of the processes on the surface is no different, but the durability is not high. This requires a number of policies to regulate the development of this industry. The lack of standards has resulted in difficulties of application, LED products, for whatever reason, the current in the channel was relatively quiet, it is difficult to do the amount. LED business of our company is the third, but less than 10% of the proportion of overall sales of our company. In the next three to five years, the LED in the application can not scale, because the current standard in the industry is very different, and use up quite ring true. Is the LED may be similar, but not the same chip used, making the price difficult to unify technical instability, leading to some quality issues remain unresolved, making a short period of time the LED is difficult to replace the sodium lamp, because use the LED is not as secure as the traditional lamp. LED lighting industry to address the duplication of investment and waste of resources, currently the most important factor restricting the development of China's LED lighting LED lighting, high-end technology R & D suffer, as well as high investment and high risk, many lighting companies and stop looking. As China's LED industry to support the efforts to continue to increase, LED lighting technology is the rapid progress the field of LED enterprises almost always do the same thing, which led to serious industrial duplication and waste of resources. LED modular precisely to solve this problem. Modular development has become the industry trends, LED module will gradually extend the maturity. Of course, LED modular development of pros and cons, the LED module greatly reduces enter the LED lighting technology and capital threshold, even if the line lay members a modest investment, but also its own production of LED lighting products. This will set off a new LED boom is bound to be some non-formal manufacturers, businesses involved in some impact to this new revolution in the lighting industry. But in the long run and departure from the industry, the overall situation of the LED modular development in line with the actual situation of China's LED industry is more good than harm. The core of the competition should be focus in the channel rather than technical, the technical processing of high-power LED products on the heat dissipation problem is still not very stable, including the cooling material, the cooling mode. Moreover, the current in the LED industry, the proportion of functional lighting is relatively small, more concentrated in the LED backlight, landscape lighting above. LED technology as well as some uncertainty in the application view, the traditional lighting of the many business enterprises, dealers still waiting, watching, and once this market is really mature, they will cut through the direct way to buy light to the field of LED. Lighting industry as a whole threshold is in fact lower, so the core of competition in the industry should be in the channel, rather than technically. Channels or for the king, for example, NVC channel hard work was very good business in the country belong, as long as the time is ripe, the NVC turned to the development of LEDs, a competitive LED products on their own channels. able to quickly open up the market. LED lighting industry, modularity is an inevitable trend, because many of the advantages of energy saving, environmental protection, safety, long life, low consumption, low heat LED has been widely used in the lighting industry. The single LED power of the market, however, generally below 5W, it is difficult to become the first choice for lighting, high-power LED product prices high, it is difficult to be more acceptable to consumers. This is a rapid bottleneck in the development of the two constraints LED. At present, many companies in the development of LED projects, countries have also more attention, so that the LED industry is booming historic period. This period is a good opportunity for domestic LED manufacturers. Need to break the bottleneck problems to be resolved, a modular LED lighting industry, the application of LED technology of Aesthetic further expansion of LED applications at the same time, the rapid development of LED industry will play a positive role in promoting. LED modules will be the current lighting system have a great impact Investment cost and high-end R & D is currently plaguing the largest lighting manufacturers in the development of LED lighting project, the birth of the LED modular maximize eliminates the need for high-end technology of LED lighting R & D suffer, while a significant reduction in investment costs and investment risks. In recent years the state has vigorously support the development of the LED, the rapid development of LED lighting technology, the modular has gradually become the development trend of LED industry. The promotional efforts continue to strengthen the LED module will gradually mature, LED lighting will undoubtedly lower the threshold current lighting system to a great degree of impact. But also to attract the traditional lighting companies to upgrade to enter the field of LED lighting will play a great role in promoting China's lighting industry into new areas. Difficult for us to solve the technical problems of LED lighting, LED lamps to deal with the problem of heat, light, we have no way to solve, if we apply the direct solution, and will greatly reduce our R & D risk. The future competitiveness of enterprises is the competition of brands and services, rather than product price dispute. Therefore, we compare the recognition LED modular development. Modular development so that the LED lighting with a bright future In recent years, some of the world's economically developed countries around the development of LED launched a fierce technology race. In recent years, Japan's 21st century project "," next-generation lighting plan, the EU's "Rainbow Plan, South Korea," GaN semiconductor light-emitting Plan and other government programs have been introduced. China is the world's lighting and the largest lighting manufacturers, the town is the title of "China Lighting Capital". But our main production is in the low-end products, the market share of only 18% of the share of the world, big but not strong. The development of semiconductor lighting, and of great significance to enhance the Chinese LED industry's international competitiveness. At present, technological innovation and application development of LED products in China gradually improve more and more important, the reliability of the device location, test methods and standards Approaching All of this indicates that the Chinese LED industry has entered a new stage of development. Chinese LED industry has initially formed a relatively complete industrial chain including wafer production, preparation and packaging of the chip and LED product applications, including. Thus, the application of LED light emitting products are attracting the world's attention to the LED as a new kind of green light, it would be the trend for future development, broad market prospects and new opportunities for green-lighting production industry. Modular cottage phenomenon easy to produce, the benefits of LED modular is to focus on production and focus on technology research and development type enterprises division more clear, easy businesses to concentrate on their strengths, such as the IT industry, chip, software, do the hardware. However, its drawback is very obvious, such as LED technology may be a few corporate monopolies, profit focus is to focus on technology research and development. Such as energy-saving lamps, large enterprises can be produced, and family workshops can be assembled, in which case certain role in promoting the popularity of a new product, but also prone to a large difference between product quality at the same time lead to the confusion of the LED market, which affect consumer confidence in the LED products. The module will greatly accelerate the diversification of LED lamps, functional, and in my opinion, due to the modular technology of LED lighting industry continues to mature, the LED lamps will enter a rapid development of the fast lane. From long-term development and the interest, I think there are two points worth noting: first, it will completely change the status quo of the uneven quality of LED lamps, and gradually establish and perfect the system of quality standards of the LED lamps; Second, the LED lamps manufacturers to focus more on the lighting appearance and functionality of the design and production, and greatly accelerate the diversification of the LED lamps, and more can turn. However, it must be emphasized that the traditional lighting companies into the LED industry, must understand the market dynamics and pattern, and equipped with the talents of professional LED it be possible to control risk, the fastest expansion. Modular have the potential to change the traditional pattern of the lighting industry, as the LED lights of the industry known as the "fourth-generation light source, has attracted global attention in recent years the development of Europe and the United States or China, many lighting companies will be included in give priority to the development of strategy, but in fact at this stage there are many objective reasons, large-scale industrialization of the LED lighting also has a long-term process. If you can successfully LED modular development, the prospects are bright, and may change the existing pattern of the entire industry. Modularity is the trend, but not necessarily mainstream, LED lighting modular trend. LED light source and the drive power, cooling parts and other accessories readily available, so that the manufacturers of the appearance of novel shell lamps as competitive advantage, it makes manufacturers lost the product's core technology and R & D capabilities. Relatively low, simple assembly, it will lead to a large number of small workshops, underground factory by a simple assembly, low-cost production of low-cost products hit the market. If an industry is only a simple assembly process, I think the arrival of the next financial crisis, we can rely on to survive. Fine division of the modular industry can drive LED lighting modular development should be the future trend, the professional development of the whole industry chain, it will allow the professional advantages and efficiency of the chain link enterprises into full play, the allocation of resources will be more efficient, but also will allow late replacement and maintenance easier. Modular development, will enable the entire chain link function is the formation of fine production, and ultimately the whole lamp manufacturing costs will be greatly reduced. I think LED lighting modular development should be an effective path to solve the high cost of LED lighting. Modular can promote a certain extent, LED technology breakthrough, the LED is not mature enough as a main lighting applications, as well as heat and light fades the technical issues have not been resolved. Modular development allows enterprises to focus on technical and financial advantages to expand the focus of research in the field of upstream R & D, give full play to their advantage to do so, to some extent, the break can accelerate the LED lighting technology challenges. LED business capital market and the capacity to digest how coordination? The LED industry is now producing excess background in the prospectus of the above companies, the funds raised are used to expand reproduction. In addition, according to research, there are about 50 LED companies ready to visit the capital market fund-raising expansion, industry insiders believe that if this trend continue, the LED industry overcapacity or will exacerbate. Hot plate This year, our LED enterprises to speed up the landing of the pace of capital market. In January, Lehman photoelectric officially listed. In May, the domestic LED packaging companies Hongli Opto-electronic successfully landed on the Shenzhen GEM. In June, the Alto electronics and Chau Ming also successfully landed on the capital markets. In July, Ruifeng power to join the camp of the LED listed companies. In October Liantronics also officially listed. November 25, Kingsun in the Shenzhen Stock Exchange listed December 13 Jufei, photoelectric reviewed by the SFC. In addition to the above has been successfully listed companies, the reserve army of the plate a few. December 14, encapsulation and LED lighting products, LED light source device-based industry, Mason Technologies will be reviewed. December 16, the rectangular semiconductor and Liard photoelectric two will ring the door of the Commission issuance. It is reported that, in addition to the above-mentioned enterprises, the Shenzhen City alone there are a number of LED enterprises preparing for listing In addition, there are 50 LED business has been completed or ongoing share reform, in order to introduce the investment side, and quickly achieve market. At present, LED companies are lined up waiting to be listed year after. Capacity to digest doubt recently listed or proposed to be listed on the LED companies are mostly concentrated in the package field. Industry experts who Zhang Xiaofei, said: packaging companies in China more than 1,200 production capacity more than the market demand. In addition, phosphor and other materials prices in the packaging industry does not reduce the chip has decreased but not enough to reduce packaging costs. Packaging companies, small-scale, homogeneous competition price war, resulting in gross profit margin is getting lower and lower. In addition, Xiao-Fei Zhang said: the number of China's LED packaging companies more but fragmented industry leaders has not yet been formed. Overall, packaging companies rarely have the core technology, the homogenization of competition is serious, resulting in the industry, lower gross profit margin. In the next competition, packaging companies will be the first to face a reshuffle. Is likely to encounter areas of shuffling, the recent capital markets help, capacity is still in rapid growth. Lehman photoelectric prospectus: raise investment project is put into an annual output of the line LED devices will add 264 million SMD LED devices 480 000 000 009 600 000 in the high-power LED devices, LED display 10. 200 square meters, 360,000 of LED lighting, energy-saving products, capacity expansion and rapid. The photoelectric Jufei prospectus: the offering to raise funds, net of issuance costs, investment prioritize the order the following items: investment of 215.27 million yuan expansion project for the backlight LED devices, investment of 100.7561 million yuan for the expansion of the LED lighting device project, the investment of 46.48 million yuan for the LED technology R & D center project. Photoelectric Jufei said: The investment projects fully put into operation, the LED backlight device products new 1440 one million / year production capacity, new capacity is 2010 with an annual output capacity of 720 one million / 2 times the LED lighting device products the production capacity will increase to 660 million / year, with production capacity of 2010 with an annual capacity of 90 million / year and 7.33 times. In addition, listed companies are also plans to continue to increase to make a power production capacity of China's LED industry. Recently, Topband shares intended to vote in 380 million yuan to build the photoelectric industrial park, BDO Runda smashing the 30 billion yuan Yu Jian continent's largest LED package base, Tiantonggufen LE D projects in 360 million yuan investment, amethyst photoelectric intended to vote in 29 billion in the Xinjiang Production and sapphire crystal, LUCIDITY photoelectric ordered four of the production of LED epitaxial wafer MOCVD equipment. The corporate side of crazy expansion of production capacity has doubled and redoubled; side downstream of sluggish sales, the industry there is an excess. How to digest, will become of these enterprises need to consider. Some Thoughts on the implementation of low-carbon economy to promote the scientific development Low-carbon economy is a general term for the economic development of low carbon, low carbon industry, low-carbon technologies, low-carbon life form. Low-carbon economy with low power consumption, low emissions, low pollution, in response to carbon-based energy for the global warming impact of the basic requirements in order to achieve sustainable economic and social development as the basic purpose. The substance of the low-carbon economy is to enhance energy efficiency technology, energy technology, renewable energy technologies and greenhouse gas abatement technologies, and promote the products of low-carbon development and maintenance of the global ecological balance. This is an economic development model of the evolution from high-carbon energy era to the era of low-carbon energy. In the process of development of human society, in order to obtain the energy consumption of large quantities of fossil energy, resulting in the sedimentary carbon pool in the formation of carbon at a faster rate to the atmospheric carbon pool, causing the greenhouse effect, pollution and other catastrophic problems. According to World Bank statistics, in the 100 years of the 20th century, the human consumption of coal 265 billion tons, consumed 142 billion tons of crude oil, 38 billion tons, consumption of steel, aluminum consumption 760 million tons, consumption of copper of 480 million tons, while emissions of a large number of the greenhouse gases, the atmospheric CO2 concentration at the beginning of the 20th century, less than 300ppm (parts per million) up to the current level close to 400ppm, and clearly a threat to the global ecological balance. It is predicted that by 2050 the scale of the world economy than it is now 3-4 times higher than current global energy consumption structure, the carbon-based energy (coal, oil, natural gas) in the proportion of up to 87% of the total energy, the future If you are still the development of high-carbon mode, the middle of this century, the earth will be overwhelmed. As a result, the basic connotation of low-carbon economy development model on the agenda. The concept of "low-carbon economy" was first formally appeared in the 2003 UK Energy White Paper, Our energy future: creating a low carbon economy ", was further confirmed in the subsequent Bali Roadmap, the 2008 World Environment Day theme for change the traditional concept, the implementation of low-carbon economy, it is hoped that the international community to pay attention and take measures to make the consensus of the low carbon economy into the decision-making. At present, China-depth practice the scientific concept of development, efforts to build a resource-saving and environment-friendly society, vigorously promote the recycling economy in the central file and leaders of his speech, is repeatedly asked to energy saving, the implementation of low-carbon economy as a national development important task. As a developing country, China's population is numerous, rapid economic growth, huge energy consumption, lack of capacity for independent innovation, the pressure from the energy, the environment is enormous. In accordance with the famous Kaya formulas principle, the per capita carbon footprint (carbon footprint of a person or regional "carbon consumption") depends on several variables of population, per capita GDP, energy intensity and per unit of energy, carbon content, China
