For example, street lamps are the carrier of urban lighting, and are a large number of facilities in urban construction facilities, which play a pivotal role. The phenomenon of “road traffic lights on” in urban built-up areas is enough to show its wide distribution and power supply properties.

While it can play the lighting function, it can also integrate power supply, control and network.
