The street lights that have turned off the gate have not been closed. The street lights that are dark are still not bright! This phenomenon has been encountered by many people. Starting from the 1st of next month, the "Technical Standards for the Construction and Operation of Tianjin Street Lamps" (hereinafter referred to as "Standards") will be officially implemented. The above phenomenon will be less and less. The city's 280,000 street lamps will be switched in the most energy-efficient way to ensure Road lighting throughout the city to ensure traffic safety.
According to reports, the "standard" has reclassified the way the street lights are turned off, that is, 22 hours off the river lights and landscape lights, 23 hours off some areas of street lights, half off the morning half of the street lights and other group control methods, turn off the lights according to requirements and Important holidays can be adjusted accordingly. For the expressway, main road and secondary trunk road with dual light source lamps (or three light sources), the method of shutting down the three traffic lights (two light source lights) is adopted in the traffic flow and the pedestrians are sparse. The specific method of turning off the lights is divided into two rows of double fire lamps and two side three fire lamps. Among them, the fast road and the slow road have a fire, and the slow speed road in the morning is a fire; the fast road is two fires, and the fire is closed in the morning. On the fast road, the two fires and the slow speed road are on fire. In the morning, the fast road and the slow speed road are each fired. On both sides of the fast lane, the fire is on the side of the sidewalk.
In addition, the "Standard" also requires the use of a single row of lights on a road with a road width of less than 30 meters and a street lamp with a double-row single-source light. The time for turning off the light can be delayed, the uniformity of illumination and the average illumination. Can be relaxed appropriately. When choosing whether to turn off the left or right row of lights, consider the problem of which traffic on the side of the road where the intersecting roads are relatively small and the illumination of the grounding belts with other roads. Street lights that are specifically designed to illuminate the sidewalk should be closed in the early hours of the morning; the streetlights between the sidewalk and the motorway are either Y or T-shaped, and the streetlights on the side of the sidewalk are also closed in the early hours of the morning. When the street light is a single row of lights, the road with a width of less than 20 meters is allowed to adopt the energy-saving mode of bright and light, and the uniformity of illumination can be lowered.
According to statistics, there are currently 280,000 street lamps in the city, of which nearly 80% are managed and maintained by the Municipal Street Lamp Management Office. In order to meet the dual requirements of street lighting and energy saving, the city's street lamps have been basically replaced by incandescent or energy-saving lamps into high-pressure sodium lamps. In addition, the decorative lighting should match the residential environment and buildings to achieve an aesthetic effect. In order to reduce or eliminate the obstruction of the road lights on the roads on both sides of the road, the relevant departments will regularly pruning the branches and trees for the road sections where the existing road trees in the urban area seriously affect the road lighting function.
