Feasibility analysis of application of LED street lighting

The importance and urgency of energy conservation and emission reduction

According to international authorities predict that in twenty-first Century will enter a new era of LED lighting light source. The fourth generation light source. LED development history of only several decades, but the application in the field of lighting and new technology, its luminous efficiency gradually improved, the LED market is more extensive, especially in the global energy shortage has attracted much attention from all walks of life under the background of LED green lighting market prospects attracted global attention highly. The industry believes that the next twenty years it will replace incandescent, fluorescent and tungsten lamp to become the largest and most potential market. Energy saving and emission reduction is an important measure to implement Scientific Outlook on Development, to build a socialist harmonious society, is the inevitable choice for the construction of a resource-saving and environment-friendly society, for the adjustment of economic structure, change the mode of growth, improve people's quality of life, safeguard the nation's long-term interests, has a very important and far-reaching significance. It is also our responsibility to the international community. We should fully understand the importance and urgency of energy conservation and emission reduction. Lighting accounts for 20% of global energy consumption. China's outdoor road lighting accounts for about 30% of the total lighting electricity consumption, energy saving new energy and energy saving is the world's pursuit of the goal, is an inevitable sunrise industry. According to statistics, in 2006 the global solar output value of $12 billion 400 million in 2008 will grow to $26 billion in 2010 is expected to be $42 billion 200 million, an average annual growth of 36%. LED semiconductor lighting, energy saving (than traditional energy-saving lamp energy saving more than 80%), can completely replace the existing public lighting and household lighting, if the 80% LED lighting products, the annual savings of Three Gorges power station generating capacity of 84 billion 700 million degrees a year. Market size will reach 5 trillion yuan. Road lighting is a new market for LED. The digital revolution ushered in the 6 industry: innovation, innovation and basic principle of software industry, new energy industry, energy industry, basic materials and new components, electronic manufacturing equipment. Basic innovation, innovation will continue to be a powerful driving force for economic development, through basic innovation, innovation, will subvert the industrial structure and product structure. China industry not to blindly follow the developed countries, must carry on the innovation, principle of innovation industry, vigorously develop the basic industries. The chairman of the International Commission on illumination Fulangxici. Hans Berger in the photoelectric forum and cross-strait industrial docking meeting called for LED on the good road lighting prospect that China walk in the forefront of the application of LED lighting technology. Energy saving and emission reduction is the inevitable choice for China's sustainable development, energy saving and emission reduction is the inevitable choice to meet the challenges of resource scarcity and environmental carrying capacity. In recent years, the problem of resources and environment is becoming more and more serious in our country. In the case of resource scarcity and environmental carrying capacity is limited, the traditional high input, high consumption, high emission, low efficiency growth has come to an end. Do not accelerate the transformation of economic development mode, resources are difficult to support, the environment is difficult to accommodate, the community is difficult to bear, it is difficult to achieve scientific development. Energy saving and emission reduction is a strategic measure to follow the law of development of human society and conform to the trend of the world today. Since the industrial revolution, the rapid development of economy in the world, especially in the western countries, is at the expense of a large number of consumption of energy resources, and has caused the deterioration of the ecological environment. Studies have shown that over the past 50 years, the global average temperature rise, more than 90% of the use of oil and other fuels produced by the increase in greenhouse gases, resulting in a series of ecological crisis. Saving energy resources and protecting the ecological environment has become the consensus of people all over the world. To protect the ecological environment, developed countries should assume more responsibility. Developing countries should also play the advantages of backwardness, to avoid the developed countries, pollution, governance, the old road. For China, to further strengthen the work of energy-saving emission reduction, deepen the understanding of both the development of human society, but also actively respond to the urgent need for a global climate change, is a strategic choice to establish the image of a responsible big country, taking a new road to industrialization. Ministry of finance, the national development and Reform Commission from this year in the country to implement efficient lighting products to promote financial subsidies. Subsidies take the indirect subsidies, by enterprises according to the bid agreement to supply price minus financial subsidies (bulk users by the successful supplier of protocol 30%, the price of urban and rural residents by 50% subsidies) after the sale price to the user, the central government will finance should direct subsidies funds transfer promotion enterprise. This is the first time the use of financial subsidies to support the majority of consumers involved in the promotion of energy-saving products, but also financial subsidies to promote energy-saving product innovation mechanism. To promote the development of environmental protection and energy saving. At present, the consumption of lighting accounts for 20% of the total electricity consumption, so greatly reduce the lighting electricity is an important way to save energy. In order to achieve this goal, the industry insight to research and develop a number of energy-saving lighting appliances. The superiority of LED with high luminous efficiency, long life, energy saving and safety of its inherent, attracting the attention of the world, the United States, Japan, EU and other countries and regions of Taiwan, in the new century green lighting LED new light source, practical research and new achievements. In recent years, Japan's Nichia chemical, TOYOTA, and SONY, LED are good friends of electrical lighting products available. PHILPS, OSRAM, GE and other famous lighting companies have also invested a lot of manpower and material resources
