For example, when it is dark, the staff will manually turn on the switch of the street lamp to make it light up; At dawn, the staff will manually turn off the switch of the street lamp to put it out. The advantage of this control method is simple operation, but the disadvantage is that it requires manual participation, and the workload is large and not intelligent enough.

Automatic control refers to controlling the switch of street lamps through automation equipment. In this control mode, the switch of the street lamp will be automatically adjusted according to certain conditions and rules. Common automatic control methods include light control, time control and induction control.

Lighting control is to control the switch of street lamps according to the intensity of light. The light control equipment will sense the light intensity of the surrounding environment, and when the light is weak to a certain extent, it will automatically turn on the switch of the street lamp; When the light is strong enough, automatically turn off the switch of the street lamp. This control method can automatically adjust the brightness of street lamps according to actual needs, saving energy.

For example, when it is dark, the time control equipment will automatically turn on the switch of the street lamp according to the preset schedule; At dawn, the time control equipment will automatically turn off the switch of the street lamp according to the preset schedule. This control method can automatically adjust the switch state of street lamps according to the change of time, and improve the lighting effect.

The induction control equipment will sense the flow of people or cars around and automatically turn on the switch of street lamps when people or cars pass by; Turn off the switch of the street lamp automatically when no one or car passes by. This control method can automatically adjust the brightness of street lamps according to actual needs, improve the lighting effect and save energy.

In a word, the control methods of street lamps mainly include manual control and automatic control. Automatic control methods include lighting control, time control and induction control, which can automatically adjust the on-off state of street lamps according to actual needs, improve lighting effect and save energy.
