A road illuminates an industry
Xiaobei 1st Road, Tiexi District, Shenyang City, is not too long or wide. It is an insignificant road. A streetlight renovation that can be done here has created a world record. According to the inspection of the Institute of Electronic Science and Technology Information of the Ministry of Information Industry, this is the first urban standard road in the world to implement functional lighting with high-power LED street lamps.
After research and careful comparison, the National Development and Reform Commission's research team calculated an account: the difference in power consumption between the two sources is based on the difference in power consumption. According to the daily use of 10 hours, each street lamp can save 1 per day and 1 kWh per day. ; Xiaobei 1 Road 58 lights, saving 27,732 kWh per year, saving electricity costs 18,026 yuan. According to the plan to promote the use of LED street lamps in Tiexi District, all 7800 street lamps in the district will be retrofitted with LED street lamps, saving at least 5 million kWh per year and saving more than 3 million yuan in electricity bills. This has not taken into account the savings in cable, power distribution, power consumption and maintenance of LED street lights, and does not take into account the long life of LED street lights. If Shenyang City replaces all LED street lights, it will save hundreds of millions of dollars every year. For Shenyang, which is dominated by thermal power generation, it is equivalent to saving about 60,000 tons of standard coal per year and reducing carbon dioxide emissions by nearly 110,000 tons.
From a national perspective, according to the statistics of the national street lamp industry in 2006, the national urban road lighting street lamps are 15 million baht, and the average annual growth rate has increased by more than 20% in recent years. Together with the illumination of other incandescent lamps and fluorescent lamps, the total amount is more than 90 million baht. If all of them are replaced by LED lighting products, the annual power saving will be more than 100 billion kWh, equivalent to the full-scale annual power generation of the Three Gorges Project. In China, electricity consumption for lighting accounts for about 12% of the total electricity consumption of the whole society. In the context of protecting the environment and saving energy and reducing emissions, LED lighting that truly opens up the era of green lighting has a broad use.
LED lighting, known as the fourth generation of light source after the light source, incandescent lamp and gas discharge lamp, has the advantages of environmental protection and a large amount of energy saving. It is known as the technological revolution in the field of lighting. What is it magical about? The reporter interviewed Da Ming Li Guang Lighting Co., Ltd., which has made substantial breakthroughs in the field of high-illumination LED. This is the world's first professional semiconductor lighting product manufacturer that applies high-efficiency high-power LED to urban standard road lighting and successfully realizes industrialization. .
Lin Yuejiang, the person in charge of the company, said that in fact, LED lighting is not new, and has been widely used in people's lives, from mobile phones, computers, digital cameras to automobiles, instrumentation indicators, urban landscape lighting, everywhere. However, because of the obstacles in key technologies, there has been no breakthrough in large-scale general lighting applications such as urban lighting street lights and building exterior spotlights. When the whole world was "cracked" here, "Da Ming Li Guang" 10 years of painstaking research and development finally came to the fore, and took off the pearl of the semiconductor lighting crown. "It can be said that a lamp has illuminated a new road for the energy-saving industry." Lin Yuejiang raised the topic and was still very excited.
A series of breakthroughs to meet multiple needs
Extensive construction of villagers' activities in rural areas and the erection of street lamps are one of the practical things for farmers in the construction of new rural areas in Shenyang. However, the square is bright, the street lights are on, and who is responsible for the electricity bill? Is there a way to benefit the peasants without increasing the burden on the peasants?
The villagers of Siwang Village, Liaozhong County, Shenyang City, used to go to the newly built village square to go to the gym and twist the songs. This square covers an area of ​​1,500 square meters and has 6 LED lights to provide night illumination for the square. The original plan selected 125W high-pressure sodium lamp, and finally decided to use the "Da Ming Li Guang" solar LED lighting system. The lighting effects of the two lighting schemes are quite similar. The light source of the "Da Ming Li Guang" solar LED lighting system is obviously superior to the traditional lighting products such as high pressure sodium lamps in terms of energy saving effect, color rendering and life. The square is newly installed with a lighting system. Compared with 1 traditional street lamp, the cost of one solar LED lighting system is 315?6 yuan per year. Each villager's square saves 1,533 kWh per year, saving 1893 yuan per year and backing 8 yuan. Perhaps a lot of terminology and comparative figures are not as direct as the feelings of the villagers. The most satisfactory advantages of the villagers are two--zero electricity and maintenance-free.
Sun Dong, director of the Construction and Construction Office of Shenyang Municipal Construction Committee, believes that the use of solar energy by LED provides an opportunity for the promotion of public welfare lighting in the new rural construction. On the basis of the pilot, Shenyang City will promote the energy-saving lighting construction of more than 100 village-level public service centers every year.
People's expectations for LEDs are obviously not only energy-saving, but also environmentally friendly and healthier. Since the LED semiconductor solid-state light source is non-polluting, there can be more changes in the shape, so the new solid-state electric light source LED lamp will provide more choices for consumers who have special requirements for electric light source modeling.
Beyond environmental protection, consumers are increasingly focusing on “green lighting†that is good for health. Given the stimuli of fluorescent strobes, many consumers have begun to choose carefully in the market. Recently, many cities have included the replacement of high-efficiency lighting sources in primary and secondary schools as “an important fact that directly affects the lives of the peopleâ€. And the real lighting fixtures with good color rendering, no stroboscopic light, soft light and so on, have to be the first LED.
It is based on the unanimous optimism about the prospects of LED lighting. The developed countries in the world are competing to list it as one of the priority industries, and are all committed to the conversion of LED technology into the intellectual property of general lighting. At present, in the entire industrial chain of LED, the epitaxial wafer and chip technology in the front stage of the industry are mature, and there is a large amount of production capacity to be released in the industry; the manufacturing of lamps in the latter stage of the industry and the solar energy and storage batteries that match LED lighting are even more The technology is mature, the industry is mature, and the production capacity is huge. The problem of light source packaging technology in the middle of the industry is the bottleneck of the whole industry development. Whoever gains a breakthrough in this industry link, whoever has the initiative to integrate the entire industry chain, thus gaining the opportunity of development . "Da Ming Li Guang" has made breakthroughs in the technology of high-power LED heat dissipation and packaging. It has core technology in phosphor powder, heat-dissipating resin, package mode, bracket structure, optical structure, etc., effectively solving the light source. The world's problems such as heat balance, light decay and uniformity in the package occupy the commanding heights.
However, relevant domestic experts have also expressed some worries: Can China's energy-saving products be rapidly promoted? Can China's technological breakthroughs in LED R&D maintain its advantages?
A technology triggers fierce competition
At present, the research and development advantages of our LED street lighting are only the relative advantages in the development of the industry. The most pressing problem at present is the transformation of technology and the expansion of the market. On the one hand, it is necessary to rapidly strengthen the LED industry base and enhance the core competitiveness of leading products; on the other hand, it is necessary to concentrate the efforts of all parties to cultivate and establish the market advantage of high-tech products with independent intellectual property rights in China. Experts worry that if we can not form an effective LED lighting technology industry chain in the shortest time, occupy and control the huge space of the domestic market, LED products in developed countries and regions will soon be replaced.
Many famous lighting companies in the world are gradually increasing investment in the development of the Chinese market. If we are only smug with technology, then the advantage is short-lived. The possibility that the core technology of light source packaging will integrate the upstream and downstream industry chains to form an industrial cluster will also disappear, and the opportunity will pass us.
Looking back at the domestic promotion of energy-saving products, it is actually not smooth. The data shows that 90% of the world's energy-saving lamps are produced in China, while the proportion of domestic energy-saving lamps in China is less than 20%. The gap between production capacity and use reflects the lack of awareness of social energy conservation. The "Energy Conservation Law" has been in existence for 9 years, and it has been proposed that street lamps have been energy-saving for more than five years, but the energy-saving renovation of street lamps has not received the expected results. At present, most of the lighting in public places in China (such as traffic tunnels, streets, parks, etc.) mostly adopt traditional power supply lighting methods, most of which are not energy-saving. The light sources of street lamps are mainly high-pressure sodium lamps and mercury lamps. In some countries, such as Germany and Japan, legislation has stipulated that some high-energy-consuming light sources cannot be used, such as outdoor landscaping lighting and non-essential lighting.
If you don't save money, it's hard to let the people take the initiative. Liu Hong, an associate researcher at the Energy Research Institute of the National Development and Reform Commission, said that it is far from enough to calculate the electricity bill in the consumer market. It is also necessary to calculate the cost account and quality account, and establish an energy-saving interest-oriented mechanism. Improving quality and reducing prices is becoming a top priority.
At present, it is particularly urgent to promote energy conservation through the system. At the national teleconference on energy conservation and emission reduction work held in April this year, the State Council required to focus on ten key energy-saving projects, including green lighting, and proposed to promote 50 million high-efficiency lighting products this year. This is a few hundred. The billions of billions of municipal policies often guide and encourage the use of LED energy-saving lighting, which is inseparable from the leverage of government departments.
Experts believe that in some important areas, the government should take the initiative to share certain technological innovation risks, effectively protect the innovation results of enterprises, and provide policy support for some innovative products whose public interests are greater than the users' own interests. Many experts and industry insiders believe that the state should take measures to increase supervision, promote urban public lighting energy-saving renovation, and promote the use of environmentally-friendly and energy-saving lighting products as soon as possible. At present, although many places have introduced some subsidies for the promotion of energy-saving lamps, China still lacks national financial and tax incentives to encourage the production and use of high-efficiency lighting products. The promotion of energy-saving lamps also lacks effective investment and financing channels and incentives. mechanism.
“Although we are facing double pressures, we are also on the threshold of dual opportunities.†The head of “Da Ming Li Guang†believes that energy shortage and environmental pollution are two major problems facing China’s sustainable development. The task of energy conservation and emission reduction is very weight. Vigorously developing the high-efficiency and energy-saving lighting industry has emerged as the times require. “Da Ming Li Guang†has industrialized the latest energy-saving lighting technology achievements when the country needs it most. The "collision" of internal and external forces, and the sparks that are wiped out are the bright prospects for the popularization of domestic LEDs. The person in charge of the company further analyzed that some lighting companies in China already have certain technical and industrial bases in the field of LED lighting.
At present, the high-power LED street lamp independently developed by “Da Ming Li Guang†has been installed in Sichuan, Hebei, Guangdong, Beijing, Shaanxi, Inner Mongolia and other places since it was successfully applied to urban standard road lighting in Shenyang. At present, in the Beijing Olympics group project, China Lighting has become the biggest winner of the Olympic lighting project. This shows that China's national enterprises have already had the strong strength to compete with foreign lighting giants. Domestic high-power LED street lights only need to be further upscale. Under the support of policies, a complete industrial chain will be formed, which will turn technological advantages into industrial advantages and turn industrial advantages into market advantages, thereby enhancing international competitiveness.

How is LED energy saving?
LED, simply understood, is the semiconductor light-emitting diode, which is the most advanced lighting technology in the world. The LED lamp is not the "old face" of the filament plus the bulb, but a solid-state light source made of a semiconductor chip. It uses electron movement to illuminate and directly converts electrical energy into light energy. Therefore, the power consumption of the LED is only 1/10 of that of the conventional bulb, and the service life is 100 times that of the conventional bulb.
An ordinary energy-saving lamp has a life of more than 5,000 hours, which is five times that of an incandescent lamp. The high-quality energy-saving lamp can recover the cost after using it for about one year. The life of the high-power LED light source is more than 50,000 hours, and there is almost no maintenance cost. The return of one-time investment is more obvious.
Lighting experts pointed out that most energy-saving lamps, although more energy-efficient than incandescent lamps, are essentially fluorescent lamps that emit light through low-pressure mercury vapor discharges to illuminate rare-earth trichromatic phosphors. Currently, they can only be made into double-ended slender tubes. Therefore, the space for improvement of energy-saving lamps is very limited. Moreover, many of the energy-saving lamps contain mercury and the like which are harmful to the environment. If the lamps are discarded at will, it is prone to energy saving and environmental protection. The semiconductor solid-state light source such as LED is different from the fluorescent lamp in technology. The semiconductor lighting uses a cold light source, does not need to be inflated, does not require a glass casing, does not add mercury, and can be said to be completely polluted from the production process to the use process until scrapping. . In addition, LED lighting also has good color rendering, no stroboscopic, soft light and other characteristics.
In order to achieve energy conservation goals abroad, a series of policies and regulations have been introduced to encourage the production and use of energy-saving lamps. It is understood that incandescent lamps are no longer sold in the EU market. The EU countries not only compensate enterprises that develop low-cost, long-life energy-saving lamps, but also compensate households that purchase energy-saving lamps.
