Yesterday, the relevant person in charge of the city street lamp management center introduced the city service management broadcast. In the next few years, the 55,000 high-pressure mercury lamps installed in the community and Hutong will be gradually eliminated and replaced by more energy-saving light sources. In addition, the numbering of 176,000 street lamps will be completed, and citizens will be able to determine the location of help and alarm based on the streetlight number.
According to the person in charge, the current street lamp system mainly uses high-pressure sodium lamps and high-pressure mercury lamps. Among them, 113,000 high-pressure sodium lamps are used in urban trunk roads, secondary trunk roads and branch roads. 55,000 high pressure mercury lamps. In order to better achieve energy-saving effects, the relevant departments will gradually replace these high-pressure mercury lamps in the next few years. In addition, the street lights are now trying to use some new light sources such as electrodeless lamps and metal halide lamps with long life and good energy saving effect.
Not only that, the street lamp management center has adopted Other energy-saving methods, one of which is to implement midnight lights in conditional areas, that is, different lighting conditions before and after 24 o'clock. At present, the street lights that implement the midnight light include a double lamp, a double arc lamp, and a double row lamp segment. The designer sets the street light to a midnight light according to the road level and traffic flow. These lights work all in the middle of the night, and after 24 o'clock, they will stop part of the illuminance. Considering that the voltage is generally high in the latter half of the night, the street lamp management center also uses related technologies to reduce the street lamp voltage to extend the life of lamps, light sources and other equipment.
At present, the street lamp management center is numbering and locating 176,000 street lamps one by one. After all the work is completed, this information will be provided to relevant departments. Once the public asks for help or alarms, if they do not know their location, as long as the street light number is reported, the relevant department can determine its location. At present, the numbering work has been carried out on the Second Ring Road and some main roads. The public can see the yellow number about two meters from the ground.
