Tianjin street lamp equipment implementation of new standards


The reporter learned from the Municipal Street Lamp Management Office yesterday that the “Technical Standard for the Construction and Operation of Tianjin Street Lamp Equipment” has been implemented since September, in order to guide the city’s urban lighting to “efficient, energy-saving, environmentally friendly and healthy”. development of. Create a good visual environment for vehicle pedestrians, and achieve the purpose of ensuring traffic safety, facilitating people's lives and beautifying the city's cityscape.

Under the premise of clarifying the technical standards, operation market management and unified street lighting management system of streetlight construction and maintenance management in this city, the communication standards, technical standards, input current simulation, data accuracy and safety related to street lighting Sex and electromagnetic compatibility have been regulated, especially in the area of ​​street lamp energy saving. The standard requires that the equipment selected in the future construction of street lamps should have a nominal power saving rate of more than 15%; no-load loss less than one-thousandth of a thousand, and load loss less than three-thousandths; equipment overload capability can reach 120% in overload. 30 seconds, automatically cut to bypass when exceeded; the service life reached 15 years under the condition of 24 hours of charging. In terms of energy saving of lamps, the standard requires high-efficiency gas discharge sources with high luminous efficiency and long life. The expressway and trunk roads must adopt light-cutting and half-cutting lamps, and require high illumination efficiency and uniform brightness. Decorative lighting can be used in residential roads and commercial streets, but in combination with energy-saving requirements, the premise of ensuring brightness is small, and the number of lamps is minimized. The lamp-on current of the energy-saving lamp ballast should be 15 (10) times or less of the normal current, and the service life should be more than 10 years. In addition, the standard also specifies specific energy-saving methods such as midnight lights.
