Traditional street lamp structure

In fact, there is no essential difference between ordinary street lamps and other lighting tools. Or a group of incandescent lamps (or other lamps) in parallel. Just to simplify the operation, a street lamp controller is added, which can automatically switch on and off with the light and shade of natural light or the artificially set time (as shown in the figure).

Each lighting unit consists of a lamp pole, a lamp arm, a light source and a lampshade. The lamp pole can also be replaced by other wire poles, which only consist of lamp arms, light sources and lampshades.
