Foreword: Lighting is a marginal applied science, and it is inextricably linked with the survival, development and progress of human beings. It involves a wide range of aspects, not only related to architecture, but also closely related to many aspects of industry, agriculture, transportation, medicine, culture and art, scientific research and national defense construction. Today, with the rapid development of science and technology and the continuous improvement and improvement of the human living environment, lighting and the environment, lighting and energy are closely related. Green lighting is the product of human social progress, the cradle of human survival, the symbol and symbol of social civilization, and has quietly entered the ranks of “green environmentâ€.
Green lighting is a high-efficiency, economical and comfortable modern lighting system. It refers to the use of scientific design, high-efficiency, long-life, safe and stable lighting electrical products, including: electric light source, lamp electrical accessories, lamps, Wiring equipment and dimming control equipment and light control devices to achieve high efficiency, comfort, safety, economy, environmental protection and improvement of the conditions and quality of people's work, study and life, as well as the lighting system that is beneficial to people's physical and mental health and reflects modern civilization. .
Green lighting project is a fairly complex social system project, which includes a wide range of comprehensive content, clear energy conservation goals, and close relationship with environmental protection and pollution reduction. It is an important part of protecting human ecological environment and conserving resources. This article only covers urban landscape lighting. Some views on energy conservation in the construction of light environment.
First, the significance of implementing green lighting and the importance of energy saving
Green lighting was first proposed by the US Environmental Protection Agency. China Green Lighting Project was initiated in 1996 by 13 former ministries and commissions of the United Nations Economic and Trade Commission. The purpose is to develop and promote high-efficiency lighting products, save electricity, protect the environment, and provide an efficient, safe, comfortable and economical lighting environment for the whole society. Promote the development of China's lighting electrical industry. So far, the project has been implemented for a full decade, spanning three national five-year plans, and has been listed as a national key energy-saving demonstration project. The implementation of the project has received strong support from governments at all levels and active participation from all walks of life. It has achieved remarkable social and economic benefits and has become an important measure to implement China's sustainable development strategy.
At present, human society faces three major problems: population growth, resource depletion and ecological environment deterioration. Therefore, controlling population, conserving resources, and protecting the environment have undoubtedly become the three major themes of common concern in the world today. In the voice of the global wave of green civilization to protect the ecological environment, we must not ignore the important issue of green lighting.
As the world's energy consumption increases, the emission of environmental pollutants such as carbon dioxide, nitrogen oxides and dust particles increases year by year, and the impact of fossil energy on environmental pollution and global climate will become increasingly serious. According to EIA statistics, the world's carbon dioxide emissions in 1990 were about 21.56 billion tons, reaching 2.39 billion tons in 2001. It is expected to be 27.72 billion tons in 2010 and 37.12 billion tons in 2025, with an average annual growth rate of 1.85%. China has its own national conditions. As early as 1993, China has surpassed Russia to become the world's second largest energy consumer. In 1996, the total primary energy consumption reached 35EJ (about 830 Mtoe), which is three times the energy consumption of India, 40% of the US energy consumption, and the average American energy consumption is 12 times that of the Chinese. Among the world's seven largest energy consumers, only China's energy structure is special: coal accounts for more than 72% of energy consumption. The characteristics of China's energy resource reserves structure and the characteristics of China's economic structure determine China in the foreseeable future. The coal-based energy structure is unlikely to change. The difference between China's energy consumption structure and the world's energy consumption structure will continue to exist. This requires China's energy policy, including energy infrastructure construction, energy exploration and production, energy utilization, Policies for environmental pollution control and the use of overseas energy should be different from other countries. In view of China's large population, limited resources for energy resources, especially high-quality energy resources, it is in the middle of industrialization. Special attention should be paid to relying on scientific and technological progress and policy guidance to improve energy efficiency, seek clean utilization of energy, and actively advocate energy, environment and economy. sustainable development. Therefore, China's green lighting project is in the critical period and stage of inheriting the past and opening up and innovating.
The core of green lighting is energy saving, and the ultimate goal of efficiency improvement is to save energy. China is a big country with a population of more than one billion and a vast territory. If you save everywhere and save everyone, it is really a great number. The Party Central Committee called for the construction of a conservation-oriented society and the building of a harmonious society. Savings include various resources, of which energy is an important aspect. The Propaganda Department of the Tianjin Municipal Party Committee, the Municipal Economic Commission, the Municipal Federation of Trade Unions, the Municipal Electric Power Company, and the Municipal Energy Conservation Association have jointly issued the "Promotional Power Proposal", initiating the initiative of all citizens to save every degree of electricity as much as possible to ensure normal life. Electricity and the sustainable development of the city's economy make its own contribution. We can roughly calculate the account: one power can run the refrigerator for one day, you can boil 8 kilograms of tap water, you can make the TV work for 10 hours. Saving one kilowatt of electricity saves 4 liters of water and 400 grams of coal. Therefore, the whole society should further enhance the awareness of power saving, establish a glorious glory, waste shameful thoughts, and develop good habits of saving. Starting from me, starting from small things, we will form a good social atmosphere that saves electricity, uses electricity, and uses electricity safely.
Night landscape lighting is also a big consumer of electricity. In the field of lighting, although the construction of urban landscape lighting environment is a new thing, it has been implemented for more than ten years, and it has experienced “nothing†to “havingâ€, from “small†to “bigâ€, and from “lighting†to "Beauty", from "custom" to "elegant", from "construction practice" to "theory research", has the development and innovation of "light up", "beautiful", "artistic taste" and "light culture" The process has been successful, insufficient or failed. Design is the overall factor of overall management. The advantages and disadvantages of lighting design play a decisive role in the correct selection and promotion of high-efficiency energy-saving lighting equipment. It plays an important role in improving lighting quality and creating a good light environment. Savings and waste also play a vital role.
