LED highway lighting system is not unified, and application standards need to be formulated urgently2

Recently, 2013 Smart Transportation LED energy saving and emission reduction technology and standards seminar. The participants and experts held high-level discussions on further promoting LED application technology in the future national highway lighting and variable signal display fields. The State Council's 12th five-year plan for energy conservation and emission reduction has put forward new requirements for the application of LED roads. The State Council has successively issued the '12th five-year comprehensive work plan for energy conservation and emission reduction' and the '12th five-year work plan for controlling greenhouse gas emissions'. five final energy consumption and carbon dioxide emissions per unit of GDP in the country decreased by 16 and 17 compared with 2010. In the transportation industry, road transportation accounts for 39. Of the total energy consumption. 5. It is imperative to promote green and low-carbon transportation. Since 2011, the National Ministry of Transport has set up a special fund for energy conservation and emission reduction in transportation to encourage enterprises and institutions to obtain application results in energy conservation and emission reduction. five batches of 100 ministerial-level energy-saving and emission-reduction demonstration projects have been launched. This fund focuses on innovation in system, management and technology to drive the development of green transportation. In the field of transportation, how to give full play to the energy-saving effect of LED lighting and display products more effectively, so as to make the heads of highway construction and design units in various provinces and cities agree and accept the LED transformation scheme, it has also become a topic discussed by many experts. Experts believe that LED road lighting and display need to provide multi-level, energy-saving and emission reduction programs in order to win market recognition. It is imperative to strengthen the formulation of LED highway application standards. How to strengthen the standardization of LED industry has become a topic of general concern to people in the industry. The disunity of highway lighting system is not conducive to ensuring the quality of LED highway lighting products, and will bring many troubles and problems to the procurement, installation, maintenance and service of products. In this regard, Jiang Haifeng, an associate researcher at the Institute of Highway science of the Ministry of Transport, explained in detail the 'Highway LED Lighting' standard and the tracking test results of the LED lighting demonstration project of the three ministries and commissions, pointing out a new direction for the development of the industry. The three ministries and commissions tunnel LED lighting demonstration project involves 15 road tunnel LED lighting demonstration projects, spanning 14 provinces and cities. Through strict experimental measurement, it is finally concluded that LED lamps are higher than high-pressure sodium lamps: the average power saving during the day is about 73. 1, 72. 6 and 61. 4; Fine dimming is more graded dimming: 48h average power saving is about 32. Conclusion of 07. The 'Highway LED Lighting' industry standard compiled by the highway Science Research Institute of the Ministry of Transport and Shanghai Sansi and other units, finally, the scope, normative reference documents, terms and definitions, classification and naming, technical requirements, test methods, inspection rules, signs, packaging, transportation and storage of LED highway lighting industry are discussed. clearly defined, it provides a strong basis for the standardization and development of LED highway lighting industry.
