After midnight ,the traffic flow is often small，so it is absolutely a tremendous waste of electricity with streetlamps still on. The hightlight of the design is that lampposts are equipped with electric eyes. As vehicles pass by, streetlamps 800 meters before and 400 meters after vehicles will be on, while the rest of the lights are off. In this way, we can save energy effectively, fully in line with the theme of the modern times—low carbon and energy saving.
