With China's urban development, economic prosperity, social progress and the improvement of people's living standards and the requirements for environmental quality, urban road lighting is a necessary living condition for urban residents. Urban road lighting and urban night lighting have become an important task in urban planning, construction and management.
Along with the construction and development of municipal road lighting, it is accompanied by the payment of high comprehensive lighting costs(high-energy street lamp electricity and maintenance and maintenance costs). In order to reduce the overall cost of road lighting, many cities have adopted the traditional energy-saving method -- that is, turn off some lights. While promoting urban road lighting, the full use and energy conservation have also received more and more attention from governments at all levels. It is necessary to advocate energy-efficient LED street lights and carry out energy saving work for green lighting.
