Urban lighting sets off a new standard for energy saving

Urban landscape lighting is an important manifestation of urban progress. The night scenes of many cities in developed countries are like the ocean of lights. The artistic level and cultural taste are amazing. The night scene projects in developing countries have developed from scratch and developed rapidly. The trend of energy conservation has to be followed. At the end of 1992, the Ministry of Construction issued the “Regulations on the Management of Urban Road Lighting Facilities”, which was re-released after revision in September 2001. Relevant information shows that in recent years, many cities in China have also formulated corresponding management regulations and methods. From the source, they have implemented long-term management in accordance with law, science, and orderly for urban lighting planning, construction, and operation of facilities. According to Rong Haolei, deputy director of the Institute of Light Environment Design of Beijing Tsinghua Urban Planning and Design Institute, the current problems of urban lighting are mainly reflected in: First, the lighting planning is lagging behind, the overall night landscape of the city is messy, lacking priority and characteristics. It costs a lot but does not form an overall effect. Second, the lack of scientific lighting planning, one of the reasons is that the design market for lighting planning lacks technical access thresholds, which makes the design team a mixed bag. The second reason is to cater to the will of the chief executive and surpass the economic endurance of the city to make urban lighting " Image Project" and "Policy Project". Third, there are problems in the later implementation of the urban lighting planning. First, there is a lack of management personnel with professional background. Second, the seriousness of urban lighting planning as a regulation is not fully reflected. The situation of random changes often occurs, leading to lighting planning. It is difficult to fully exert the comprehensive regulation effect. The state has taken a series of measures in response to the current shortage of power supply that has been going on for several years. In addition to enterprises to strengthen the development of energy-saving products, ordinary households actively adopt energy-saving measures, and government agencies take the lead in saving energy. Urban lighting has also become an important hill for government energy conservation. In 2004, on the basis of the revision of the “Regulations on the Management of Urban Road Lighting Facilities”, the Ministry of Construction and the National Development and Reform Commission issued a notice on the “Opinions on Strengthening Urban Lighting Management to Promote Energy Conservation Work”, requiring all autonomous regions. The municipal government directly administers the principles and main tasks of urban lighting work, adheres to people-oriented and wholeheartedly serves urban residents; adheres to economic and practical, saves electricity and protects the environment; adheres to the principle that lighting construction is compatible with the local economic level.にStandard plays the role of “Landscape Energy-saving Protagonist”. The two ministries issued the “Opinions on Strengthening Urban Lighting Management to Promote Energy-Saving Work”, and there is a catalogue on urban lighting that encourages the promotion of high-efficiency lighting products. The catalogue requires that the energy efficiency value of the electric light source products used in landscape lighting should meet the requirements of GB 19043-2003 "Energy efficiency limit value and energy efficiency rating of double-ended fluorescent lamps for general lighting" and GB 19573-2004 "High-pressure sodium lamp energy efficiency limit value and energy efficiency rating". The ballast must comply with the product energy efficiency value in accordance with GB 17896-1999 "tube fluorescent lamp ballast energy efficiency limit value and energy conservation evaluation value", GB 19574-2004 "high pressure sodium lamp ballast energy efficiency limit value and energy conservation evaluation value" The requirements for metal halide lamps and their ballasts are also being developed. The people noticed that the series of standards encouraged and promoted in the catalogue are mandatory national standards. The Opinions reveals important signals for the promotion of mandatory standards in major municipal landscape lighting projects in the future. In the view of people of insight, improving the existing urban lighting standard system, formulating mandatory standards for urban lighting projects, and formulating urban lighting planning and construction standards and light pollution control standards will surely become the government's guiding urban lighting to “efficient, energy-saving and environmentally friendly”. Important technical support for the development of health. According to relevant standards, lighting engineering designers can avoid the waste of electric energy and achieve energy saving without having to pursue high lighting quantity and quality blindly. 11 In November 2004, the National Development and Reform Commission released China's first “medium- and long-term special plan for energy conservation”, in which “green lighting project” was listed as a key project. According to the plan, lighting electricity accounts for about 13% of the national electricity consumption. The ratio of high-efficiency energy-saving fluorescent lamps to ordinary incandescent lamps is 1:2.6. Energy-efficient fluorescent lamps can replace 70% to 80% of incandescent lamps. The flow device replaces the traditional magnetic ballast to save 20% to 30%, and the traffic signal lamp replaces the incandescent lamp with a light-emitting diode (LED), which can save 90% of electricity. And pointed out that during the "Eleventh Five-Year Plan" period, the focus will be on the promotion of high-efficiency energy-saving lighting systems and rare earth trichromatic fluorescent lamps in public facilities, hotels, commercial buildings, office buildings, stadiums and residents, and the automation of high-efficiency lighting products production assembly lines. Saving 29 billion kWh.参照Energy-saving lighting design reference ににJapanese lighting expert Endo Tetsuo in his discussion has proposed that urban landscape lighting planning, need to pay attention to the three principles: な1, to ensure the safety of citizens' lives; な 2, consider the environment, energy issues ; な 3, coordination with the city's personality. Obviously, for a country with such energy shortage in China, under the premise of ensuring the quality of the project, the environment and energy issues must be the key considerations for urban lighting planning. At the beginning of 2005, several experts from the Beijing Lighting Society proposed several basic principles for the construction of urban nightscape lighting in China, including design principles according to standards and regulations. Experts involved in the research believe that night lighting standards and regulations are the basis for the design and construction of nightscape engineering, and also the criteria for evaluating the nightscape engineering design and lighting effects. Therefore, the principle of doing things according to standards should lead to design, construction and Managers attach great importance to it. In the following further investigation, the Institute also found that many of the completed night scene projects in China are “over-bright”, “not enough illumination”, “light color and architectural style are different”, or lighting equipment. The degree of protection does not meet the requirements of the specification, and the quality indicators of the lighting seriously deviate from the standards or specifications. Even a small number of designers know little or do not understand the night lighting standards, which seriously affects the design and construction level of night lighting, or wastes energy, equipment and capital. According to research and argumentation, experts believe that to overcome the above problems, we must implement the principle of designing and constructing nightscape projects according to standards and regulations, requiring design and management personnel to carefully study relevant standards, norms and documents, and deeply understand their contents, and implement them. The design and construction of the night scene project.にに At present, there are many national and local standards and industry standards related to the design and construction of nightscape engineering in China, and the system is relatively complete. Experts put forward 16 current design standards and norms that can be referenced in the report. How to measure energy efficiency にに In terms of energy-saving lighting equipment selection, both the government and individual consumers must first calculate the account, and then consider how to design various lighting facilities according to the standard based on the calculation results. A good assessment method is an excellent reference for urban lighting energy saving and household lighting energy saving. Wang Xiaoying, an expert from the Beijing Lighting Association, believes that the progress and effectiveness of the implementation of green lighting projects depends on the scope and speed of the promotion and application of energy-saving lighting products. Whether energy-saving lighting products can be widely and quickly accepted by users depends on their energy efficiency level. Power saving ability and whether it can bring corresponding economic benefits to users. Wang believes that consumers' purchase of energy-efficient lighting products generally has two effects, one is the increase in purchase costs, and the other is the decline in the cost of use. Measuring the impact of energy-efficient lighting products on consumers can be obtained through cost analysis of their life cycle, analysis of payback period, and analysis of energy-saving costs. It can be clarified which energy-saving lighting products are more economical and reasonable, and are more easily accepted by consumers. Some experts believe that in the context of the overall shortage of power supply, the huge market demand for energy-saving landscape lighting and home energy-saving lighting will become a good development opportunity for China's lighting industry. With the gradual maturity of the industry, the formulation and implementation of relevant standards, and the development of lighting technology, in the lighting market, small brands with no strength will be eliminated, and the mixed situation of disorderly competition will also end. The energy-saving renovation of urban landscape lighting will further trigger the reshuffle of the lighting industry.
