Urban road lighting is to set up luminaires on roads to provide vehicles and pedestrians with necessary visibility at night to improve traffic conditions, reduce driver fatigue, improve road capacity, ensure traffic safety, and beautify the city. Therefore, urban road lighting is an important part of urban infrastructure and plays a major positive role in improving urban functions, improving the urban environment, and improving people’s living standards. Especially during the 30 years of reform and opening up, with the increasing development of social and economic construction, the level of road lighting has become an important indicator of the speed and level of urban development.
For a long time, traditional high-pressure sodium lamps and some metal halide lamps have always played a leading role in road lighting. Their design, development, installation, application, maintenance, maintenance, standards, and testing have formed a series of standard systems. In recent years, domestic LED lighting applications have developed rapidly. Many manufacturers have successively introduced high-power LED street lamps, and are increasingly used in road lighting as energy-saving products. According to the situation encountered in the implementation of the LED street lamp demonstration project, the author of this article will discuss the development of the LED street lamp and its application.
On April 28th, 2009, the Ministry of Science and Technology approved 21 cities as "Pilot City Ten Thousand" pilot projects for semiconductor lighting application projects. The purpose of this promotion plan is to adopt a group of well-established cities to take the joint investment of the state, local governments and enterprises. The model was the first to launch pilot application of LED municipal lighting, which has provided China with a comprehensive experience in semiconductor lighting exploration. It has also promoted the independent innovation level of the industry, enhanced its international competitiveness, and promoted the semiconductor lighting industry in China to become bigger and stronger. Its main content is: Using LED as the carrier in the municipal lighting application demonstration project, selecting a number of cities, each city to promote the use of LED function lighting (street lights, tunnel lights, subway, light rail, gas station, underground parking lot and other functional lights ). In 2009, the road lighting market in China reached 28 million street lamps, and about 3-4 million lamps were newly added and replaced every year, creating a huge market for LED street lamps. The “Ten Thousand Cities” program has received positive responses from all over the country.
Tianjin is the city of choice for the "Ten Thousand Cities" program. In order to promote the major measures of the “Ten Cities and Ten Thousand Cities” program of the Ministry of Science and Technology of China, Tianjin selected Yujiang Road, Baiyunshan Road, Meijiang Road, Minjiang Road and other secondary roads to implement LED street lamp demonstration projects and launched the “LDE Road Lighting Equipment Performance Test. "Assessment" work. It took the lead in carrying out 3 laboratory tests and 12 pavement light performance tests on products from 45 LED street lamp manufacturing companies across the country. The test period is one year.
This work is not only to implement the “Ten Thousand Cities” program, but also to provide qualified facilities manufacturing suppliers for road lighting construction in Tianjin in the future, to ensure the high-level construction of road lighting facilities in Tianjin, high-efficiency operation, and standardization of road lighting. Generalization and generalization are also an excellent promotion. This test will obtain a large amount of first-hand data, and the test results will also have a huge impact on the domestic LED street lamp industry. The analysis report formed on this basis will play an important role in the promotion and application of LED street lamps in China. At the same time, it will also obtain certain testing experience and lay the foundation for the establishment of an advanced LED lighting product laboratory in Tianjin.
