Walking in the head section of the Dongjiang Dike Bridge, the careful citizens will find that the original dim traditional street lights have been replaced, and replaced by bright and beautiful LED street lights, which brings great convenience and safety to the night-time vehicles and citizens. After the installation of the streetlights at the head section of the Dongjiang Dike Bridge, it was destroyed by thefts. The transformers and wires of the base of the street lamp were stolen. The street lamps became furnishings and could not be properly illuminated. The drivers and pedestrians in the past were deeply moved at night. And walking is very inconvenient. Driver: "In the past, there was no street light. Now the LED street light is installed and the road is much brighter. It is safer to drive." According to the street lamp management department, the LED street lamp is a semiconductor lighting lamp with a light-emitting diode as a light source. Because it is a solid-state cold light source, it has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency and long service life. The unified replacement of LED street lights is of great significance to urban lighting energy conservation, and will certainly improve the safety and comfort of the Dongjiang Dike.
