Road lighting is a necessary living condition for the convenience of urban residents, and urban night lighting is a very meaningful work to reshape and beautify the image of the city, inspire people's hearts, and inspire spirits. In recent years, leaders at all levels in many large cities across the country, and even some small and medium-sized cities, have paid special attention to road lighting and night scene lighting. As an important part of the image project, urban lighting has been paid more and more attention by the government. A large amount of funds have been invested in construction and renovation, making our city brightly lit and colorful at night, but problems also follow. The consumption has been rising year by year, and some problems arising from it have gradually emerged, such as the increase in the maintenance of urban street lights, resulting in insufficient personnel; the increase in maintenance costs, excessive social costs, excessive electricity expenses, and relatively difficult financial commitments; The phenomenon of light pollution is serious... The emergence of these problems undoubtedly brings great pressure to all aspects of the work of the local street lamp management department, and they are urgently resolved. Especially in the current situation of deteriorating environmental conditions, low-carbon, energy-saving, and environmental protection have received more and more attention from people.
