Development Status and Opportunities of LED Road Lighting Industry
As the country continues to invest in road construction, the length and area of ​​urban roads have increased for many years. According to the National Bureau of Statistics, from 2004 to 2014, the length of roads in China's cities increased from 223,000 km to 336,000 km, with an average annual growth rate of 4.25%. During the period, the number of street lighting lamps in urban areas in China increased by 10.53 million. Since the reform and opening up, China's urban construction has shown a rapid growth trend. As part of the urban infrastructure, the urban lighting industry has also developed rapidly. The rapid development of urban lighting has greatly improved the quality of urban residential environment, improved the management level of urban public services, and created good development opportunities for related enterprises engaged in urban lighting industry. As the main body of urban lighting, urban road lighting has experienced rapid growth along with the rapid development of urban construction in China. As the country continues to invest in road construction, the length and area of ​​urban roads have increased for many years. According to the National Bureau of Statistics, from 2004 to 2014, the length of roads in China's cities increased from 223,000 km to 336,000 km, with an average annual growth rate of 4.25%. During the period, the number of urban street lighting street lamps increased from 1,513.13 million to 2,199.5 million, with an average annual growth rate of 8.53%. The urban road lighting industry showed a rapid development trend. In terms of the type of use of urban road lighting, according to the different road lighting sources, it can be divided into high-pressure sodium lamps, LED street lamps, energy-saving street lamps, and new xenon street lamps. With the current energy consumption and the continuous deterioration of the global environment, LED lighting products have become the first choice for environmental protection and energy conservation in the global lighting field due to their high luminous efficiency, low energy consumption, long life and high quality light. Since 2008, China's Guangdong, Shandong and other places have carried out LED road lighting demonstration projects, road lighting has become the earliest entry and formation of LED lighting products. However, due to the early maturity of LED technology, some of the installed LED street lights were replaced due to the unsatisfactory use effect, which not only made the LED street lamp enterprises suffer, but also caused some negative effects on the promotion of LED energy-saving lighting products. In recent years, whether it is LED light source or driving power source, the performance of the company's technology and products has been greatly improved. With the large adjustment of product prices and the further increase of local government support, road lighting has become the current China's LED lighting market has the highest penetration rate segment. Since 2013, some of the LED road lighting products have been officially listed as the government procurement list of energy-saving products jointly issued by the Ministry of Finance and the National Development and Reform Commission. Up to now, 322 models of LED road lighting products have been installed in 84 companies. The government prioritizes procurement. With the continuous improvement of the technical level of LED lighting products, the awareness of energy saving and emission reduction in the society has been continuously strengthened, and the LED road lighting industry has ushered in a new opportunity for development. From the 2015-2016 government procurement of LED lighting products, it is not difficult to see that the overall scale of government procurement of LED road lighting products continues to expand, and the extensive application of contract energy management mode, passed on the technical risks and business risks undertaken by purchasers. It will further contribute to the rapid and healthy development of the LED road lighting industry. In the future development road, the LED road lighting industry should combine its advantages and focus on solving problems in the process of use and promotion, so that it will continue to shine in the construction of ecological civilization in China.
