Recently, the Ministry of Science and Technology and the Ministry of Housing and Urban-Rural Development held a live meeting of the Ten Cities and Wanhao Semiconductor Lighting Pilot Project in Guangzhou. The Deputy Minister of Housing and Urban-Rural Development, Qiu Bao, on behalf of the Ministry of Housing and Urban-Rural Development, elaborated on the following three aspects: First, the promotion of LED lighting prospects and potential; Second, the main practice of the Ministry of Construction to promote LED lighting in the early stage; The basic plan for promotion.
First, the promotion of LED lighting energy saving potential is huge
Mainly in three aspects.
1. LED is promoted and applied in urban lighting. For example, only municipal lighting in 657 cities across the country (excluding about 2,000 county towns and 20,000 small towns) has 17.7 million municipal street lamps, and the number of landscape lighting is huge. As China is in the period of rapid urbanization, the urban population will increase by more than 10 million a year, and the street lights will increase by 121.5 million per year, and the process will continue for 25 or even 30 years. If the city's new street lights are all LED, and some old street lights and landscape lighting are changed to LED lighting, the potential and development prospects can be imagined.
2. Promote LED lighting in residential buildings. As a big construction country, China has built 2 billion square meters of new buildings every year, which is equivalent to half of the world's new buildings in China. There must be at least 20 lights in each building unit. In addition, during the 12th Five-Year Plan period, the government will pay for it. There are 36 million sets of affordable housing, which will have the potential of 5.6 billion LED lights. The built-up area in the city has reached more than 20 billion square meters. According to experts' estimates, if 30 LEDs are used, it can save more than 100 billion kWh. Compared with other energy-saving projects, the potential of LED lamps is very large. For example, if the national motor 50 is changed to a high-efficiency motor, it can save 3.4 billion kWh of electricity. This is because the motor energy saving 10 is remarkable. But LEDs can save more than 50 energy by replacing traditional incandescent lamps.
3. The vast rural market has greater potential for application. At present, the most urgent thing is that nearly 20 million farmers lack electricity and electricity. If these households use solar energy and LED integration to replace the power supply of large power grids, the annual electricity saved will be more than 50 billion degrees. If the traditional large power grid is extended to these remote small villages, not only will the 75 power consumption be consumed on the line, but the maintenance cost will be extremely high, and the total investment will exceed 50 billion yuan. The solar photovoltaic and LED lighting integrated facilities of the households can solve the lighting problem with only 1600 yuan per household, and the maintenance cost is extremely low. Together with the 20,000 small towns that accommodate nearly half of China's urbanized population, the LED market is huge. It can be seen that LED promotion and application is undoubtedly one of the main battlefields for energy conservation and emission reduction in China.
Second, the main practice of promoting the LED lighting in the early stage of the Ministry of Housing and Urban-Rural Development
In recent years, there have been some good practices in various places. As of 2010, after 81 investigations, 81 cities have installed more than 500,000 LED street lights, but they only account for the total number of street lights in these cities. How did you get it?
1. Ten cities and ten thousand combined with green lighting planning. Among them, it was mainly promoted by the ten cities and cities. In addition, the Ministry of Housing and Urban-Rural Development issued a planning outline for green lighting in the 12th Five-Year Plan. The outline clearly defines the quality and energy-saving level of urban lighting, and reduces the unit energy consumption of lighting. During the 12th Five-Year Plan period, urban green lighting and LED promotion should have a substantial leap forward. All localities should actively promote high-efficiency lighting products, accelerate the demonstration and promotion of new products and technologies such as semiconductor lighting and renewable energy, and realize the development mode of urban lighting. The transformation.
2. Promote demonstration projects for LED lighting applications. Through the demonstration start, the United Nations Development and Reform Commission and the Ministry of Transport of the Ministry of Housing and Urban-Rural Development launched 50 LED lighting application demonstration projects. In addition, a series of standard specifications, such as urban landscape lighting and street lighting, were modified to hinder LED applications. Some regulations, such as not allowing the lighting fixtures to be adjacent to the woods, and the old frame with a distance of more than 2 meters from the leaves, because the LED lights are not hot, can be wrapped around the tree to replace the traditional low-efficiency backlighting.
3. Started the LED street lamp and solar energy integration demonstration project. LED street lights and solar photovoltaics can be fully integrated, and the reliability and efficiency of the integrated street lights are high. For example, after the application of solar LED street lights in Yushu in the past few years, the electric lighting of the entire city was completely devastated during the earthquake, but only one main road was shining. The highly reliable solar LED streetlights survived the earthquake and laid a good foundation for subsequent rescue. Without solar LED street lights, the rescue after the earthquake is even more difficult.
4. Introduce the energy service company model to promote the overall development of the LED street lamp market. The budget for the original management of street lamp municipal service companies was limited. To apply for the modification of lamps, it was necessary to re-declare the budget. The cycle was at least one year longer and the financial burden was increased. After the energy service company intervenes, the problem can be solved. The municipal company can not pay the money, and only saves the electricity cost saved after the LED is modified every year to the energy service company, and guarantees that the investment cost can be recovered after several years. The state has introduced preferential policies for tax exemption for energy companies, and banks are willing to lend to these energy service companies, so EMC combined with LED is a very good promotion model.
Third, the next step to accelerate the promotion of LED lighting
From the perspective of economic prospects, there are several factors that promote LED applications.
First of all, in the 12th Five-Year Plan period, China has to change its economic growth model from quantitative growth to sustainable development. This is a major change and the main tone of the 12th Five-Year Plan. Promoting green lighting is undoubtedly the national industrial upgrading and national strategic transformation. An important part.
Secondly, from the local point of view, the LED lighting industry is developing as an important emerging pillar industry. LED-related industries have become a new industry to promote the upgrading of local industrial structure. Local governments at all levels will vigorously support this industry.
Again, China is currently experiencing a very difficult period. The original production capacity of LED is 70€, which is solved by export. Foreign trade exports are affected by the European sovereign debt crisis. The way for countries to cope with this new financial and economic crisis is to shrink fiscal expenditure and cut off the original LED application project. It is. At this time, if we do not expand the domestic demand for LED applications in time, then it will have a great impact on the newly cultivated LED industry, the strategic transformation of the 12th Five-Year Plan, and the development of local pillar industries. Vigorously promoting LED green lighting can be said to be one stone and three birds. We should do our best to do such a good thing.
But it is not easy to do this well. I emphasize the importance of focusing on the following aspects:
1. Strengthen coordination between departments and localities
Because the application, research and development and promotion of the LED industry involves many ministries, the policies of these ministries should be twisted into a rope, and the three goals set forth in the 12th Five-Year Plan are urgent for the country to cope with the financial turmoil and promote the local Industrial transformation needs to be promoted together, and LED development and application can lead to a new situation of leap-forward development.
2. Further improve standards and regulations
All local lighting, landscape lighting, parking lot lighting, underground space lighting, supermarket lighting, energy-efficient building lighting, including tunnels and mines, etc., should be issued and revised in a timely manner. It is necessary to promote LED lighting in green buildings and energy-efficient buildings, especially for large public buildings built by the government, government office building renovation, government-built affordable housing, including eco-city, green small town construction, etc. LED lighting.
It is worth pointing out that the promotion of LED lamps is not an innovation of monopoly energy-saving lamps, but more importantly, it is necessary to promote the energy-saving efficiency of various energy-saving lamps and fair competition. For example, in the case of high-power ultra-high street lamps, the current energy-saving efficiency of high-pressure sodium lamps is higher than that of LEDs.
3. Accelerate technology and institutional innovation
For example, LED street lighting and solar photovoltaic adopt a common mode to save energy and economic benefits. At present, solar photovoltaic has two access modes. First, the Golden Sun model often requires special land acquisition to build a large project. tens of thousands of kilowatts of solar photovoltaics are centrally connected to the power grid, and the power grid subsidizes the investment in the Golden Sun project. Because the country has not yet formed a mechanism for the grid companies to pay for compensation for solar photovoltaics and the lack of intelligent grid. The obstacle currently encountered in the Golden Sun model is that more than one-third of the power supply capacity is vented. The second is the integrated mode of solar photovoltaic and building, which does not require land acquisition, and the photovoltaic power is connected inside the user's electricity meter and is used for self-use. Since the state financial subsidies basically cover the purchase cost of solar photovoltaic devices, solar energy is self-sufficient for use, and the building using solar photovoltaics is very efficient. The inspiration for LED applications is that solar LED street lights do not necessarily have to be balanced by a single pole. For example, the solar photovoltaic energy of a series of street lamps is concentrated to supply a nearby building, and the utility street lamp is used at night because the system is cancelled. With the battery, it can save 40 investment, and at the same time, the solar power generation can increase the efficiency by 50, because the power generation margin of the solar photovoltaic street lamp can be fully utilized. This kind of solar LED street light application mode with room lead can greatly improve the reliability and efficiency of system application. Therefore, the potential of institutional and technological innovation in promoting LED promotion cannot be underestimated.
4. Accelerate the application of LED in green buildings
At present, the development of green buildings is very fast, and the country is about to introduce an incentive mechanism for green buildings. Many cities are also discussing the introduction of green building star rating methods, preferential policies and so on. Green building is the future direction. It has irreplaceable comprehensive benefits in energy saving, land saving, material saving, water saving and indoor air quality optimization. One of the key technologies is the comprehensive application of LED in lighting. The demand for LEDs has greatly increased. At the national level, green building promotion policies are being formulated. Once these policies are introduced and combined with LED promotion, the potential of the LED industry will be further developed.
5. Energy-saving service company model can accelerate the promotion of LED lighting
The Energy Service Company (ESC) model can be formed or built by existing companies. This business model can bypass a series of problems such as project approval for project renovation, street lighting renovation, and financial allocation. As long as the saved electricity costs are used as compensation for the investment and renovation of old lamps by energy-saving service companies, they can be recovered in a few years. For example, like Sweden, the population is less than 10 million, the number of energy-saving service companies exceeds 1,000, and there are only 200 in China. There should be tens of thousands in the future. At present, the state has introduced preferential policies for tax exemption and credit, once with LED lighting. The combination of transformation and transformation can greatly promote the promotion speed of LED lighting.
6. Joint selection of green lighting demonstration cities
The green lighting demonstration city can be divided into stars. For example, the one-star eco-city green lighting demonstration city must reach 15 LED lighting, and the two stars should reach 30. What are the benefits of a star green lighting city? First, for cities that have reached the star rating, several ministries and commissions will jointly give certain rewards; second, the Ministry of Science and Technology and the Ministry of Housing and Urban-Rural Development jointly awarded medals; third, the Ministry of Housing and Urban-Rural Development will select ecological garden cities and Habitat Awards in the future. In honor, we can also consider green lighting compliance as an important basic condition, and give policy support and rewards. These measures will be jointly promoted by the Ministry of Science and Technology and the Ministry of Construction. I believe that relevant departments will promote the integration of green lighting. The spring of LED lighting will come.
Finally, we also need to actively implement the speech of Minister Wan, and integrate the spirit of his speech into the practical actions of the national construction system to promote LED lighting, and implement it earnestly.
Accelerate the application of LED in green buildings
