In general, street lamps are lighting facilities installed along streets for the safety and security of street traffic, and suitable types are used depending on installation places such as highways, main roads in downtowns, commercial roads, and residential district roads.

There are several types of streetlight poles, such as the highway type that bends the end of the pole and has its back at the end, a bracket that extends horizontally at the end of the pole, and has a back on it. There is a head-mounted lamp, and a high-pressure mercury lamp, a fluorescent lamp, a sodium lamp, a light bulb is usually used.
