According to the current situation of street lighting in China, after 9 pm in small cities and after 2 am in large and medium-sized cities, pedestrians and vehicles on the roads have gradually become scarce. It is clearly unnecessary to maintain high illumination on roads with such low traffic flow from this period until 6 a.m. It is understood that urban public lighting accounts for 30% of China's lighting power consumption, about 43.9 billion kWh. Calculated at an average electricity price of 0.65 yuan/kWh, the annual expenditure is 28.5 billion yuan. In today's extremely tight municipal expenses, the vast majority of cities and regions in China have almost unanimously adopted the cost saving method of turning off street lights through separate lamps, which not only leads to uneven distribution of road illumination and poses hidden dangers to public security and traffic safety, but also damages the lifespan of street lights due to the increase in power grid voltage in the latter half of the night. A large number of lamps need to be replaced every year, so it cannot be called true energy-saving. Energy saving refers to lighting and saving electricity while ensuring the lighting effect.

The main advantage of the above intelligent control is that it significantly reduces power consumption, saving more than 40% of power consumption, and avoiding the hidden danger of turning off lights in separate lamps. The promotion of efficient and energy-saving intelligent lighting appliances, combined with the actual lighting situation to effectively utilize light energy and save lighting electricity, has extremely profound significance.
