What are the main materials of courtyard lamp poles: equal-diameter steel pipes, special-shaped steel pipes, equal-diameter aluminum pipes, cast aluminum lamp poles and aluminum alloy lamp poles? The main garden road spacing is 10m- 18m, and the secondary garden road spacing is 20m. In addition, a lamp is set at the intersection of the entrance of each unit and the main fire lane in the residential area for independent control of all-night lighting. The road is controlled by interval jumping, and the lights are turned off by half in the middle of the night, saving energy. According to the engineering practice, the dark band between the two lamps is just eliminated, which shows that the layout spacing is basically appropriate. If the height of the light pole changes, the arrangement spacing will be slightly adjusted accordingly. Before installing the courtyard lamp, the embedded parts of the street lamp foundation, that is, the concrete foundation part, should be done first. Before laying the foundation, lay the street lamp cable. The smooth installation of street lamps can be ensured.
