The two conferences that closed not long ago passed the “Eleventh Five-Year Planâ€, in which urban green lighting projects were included in one of the ten key energy-saving projects. The Notice on Further Strengthening Urban Lighting Power Saving Work issued by the Ministry of Construction (Jiancheng [2005] No. 234) also clearly states that “the use of light sources, lamps and control systems for urban lighting should give priority to the selection of energy-efficient products that have passed certification. Actively promote high-efficiency lighting source products such as high-pressure sodium lamps." These documents all reflect that China's road lighting construction is striving to transform into a "saving society". I. Basic conditions and requirements for road lighting The purpose of road lighting is to provide good visual conditions for drivers (including motor vehicles and non-motor vehicles) and pedestrians in order to improve traffic efficiency, reduce nighttime traffic accidents, and help road users see Clear the surrounding environment, identify the position; illuminate the environment and deter crime. At the same time, good road lighting can also play a role in enriching life, prospering the economy, and enhancing the image of the city. A good road lighting system must meet the following lighting requirements: 1. The average brightness should not be lower than 1 cd/m2, the total uniformity Uo = 0.4, the axial uniformity U1 = 0.5; 2. If there are non-motor vehicle lanes or sidewalks on both sides of the main road , the average horizontal illuminance should not be lower than 50% of the main road, and must ensure the recognition of non-motor vehicle people or objects; 3, if there are buildings around the road, should avoid direct light into the building; The street lamp is installed in the air above 6 meters. Replacing the street light source is a costly task, so it has higher requirements on the life and reliability of the light source. 5. The number of light sources used in road lighting is large, and the power consumption is large. Highly efficient light source. Therefore, in the use of road lighting systems, light source products with high luminous efficiency, long life and high lumen maintenance rate should be preferred. At present, from the road construction trend of China and the development trend of road lighting technology, a number of innovative and technological products, such as high-efficiency high-pressure sodium lamps, will provide strong support for China's road green lighting construction, upgrading the status of road lighting and replacing it. stand by. Second, the basic technical characteristics of high-efficiency high-pressure sodium lamp High-efficiency high-pressure sodium lamp has many advantages such as high luminous efficiency, low power consumption, long life, strong fog permeability and no attracting insects. Take SON-T Plus high-efficiency high-pressure sodium lamp, one of Philips' flagship products, as an example. Its luminous efficiency is as high as 140lm/W, which is 20% more than ordinary products, and has better energy-saving effect. At the same time, its average service life is up to 32,000 hours, which can reduce maintenance costs by about 30%. Using Philips' unique PIA integrated antenna liner structure, the Philips high-efficiency sodium lamp SON-T Plus completely eliminates the early failure of the old-fashioned bimetallic antenna, which not only significantly improves the reliability during lamp life, but also makes It is more convenient to start, and the startup time is faster. At the same time, a special Zirconium aluminum gas-absorbing sheet (ZrAl) is used to effectively avoid the early failure and the occurrence of electrolysis caused by the use of the anti-gas sheet. The arc tube used in SON-T Plus uses sodium mercury vapor and helium as the ignition gas. After 12000 hours of use, the lumen maintenance rate is still above 90%. At the same time, it is free of lead and contains low mercury (amalgam), which is very environmentally friendly and green. Third, the application of high-efficiency high-pressure sodium lamp technology in road lighting In general, road lighting costs are mainly composed of energy costs, maintenance costs, product procurement costs and distribution and installation costs. Lighting product procurement costs are only part of the overall lighting investment. For the overall replacement project, the basic proportion of the cost of the entire road investment is 4:2:1:1. Take a 10 km long road lighting project as an example, the comparison between Option 1 and Option 2: Name No. Project Plan 1

Under the same conditions, 24+31, the high-efficiency high-pressure sodium lamp and its supporting lamps and electrical appliances are used. The annual cost savings of the scheme 1 is more than 550,000 yuan, nearly 30%. This has significant practical significance for saving huge road lighting costs and fundamentally alleviating the current situation of power shortage in China without reducing the quality of lighting. IV. Use examples and promotion significance In the 312 national road reconstruction project, the Philips SON-T Plus high-efficiency high-pressure sodium lamp system was used on a large scale. In the overall implementation of the 312 National Road project, a total of: Kunshan section - 1000 sets of SGP268/250W SON-T Plus system, SGP268/150W SON-T Plus system 800 sets; Changzhou section - SGP268/400W SON-T Plus system 1085 sets, SGP268/150W SON-T Plus system 890 sets, the integrated investment makes this section of the road without the installation of street lights in the night become the most eye-catching segment of the 312 national road. We learned from the conversation with the street lamp owner and the biggest beneficiary of the street lamp, the night driver, that after the installation work is completed, the brightness of the road is completely up to standard, and the uniformity is good, which saves the owner and the maintenance cost. It also greatly improved the safety factor of road driving and achieved a true win-win situation.
