Road lighting in public places, such as highways, tunnels, district roads, corridor halls, illumination lamps in underground parking lots, needs to be kept always on in case of dim light or at night. If the power switch is not turned on, the purpose of road illumination cannot be achieved.

In fact, the time for people to use the lighting devices/apparatuses in public places is random, and the actual use time per day is at most two thirds, generally less than one half of the actual use time per day, and even less than one third of the actual use time per day. Therefore, the power consumption is increased, and the lighting lamp loss is increased. Such as district street lamp turn on all night, tunnel and underground parking garage lights need 24 hours to turn on. However, the use of these public place lighting consumers/devices is random, and normally, at least one third of the time is not used, resulting in waste of electric energy, and when the number of lighting lamps is considerable and the use rate is low, the resulting waste of electric energy is huge.
