There is a high street lamp at the intersection of the city, which is usually composed of three or four lights. Does this lamp count as a street lamp? What is the name and function?

This is called medium and high pole lamp, also called square lamp. Street lamps, of course.

The height of the pole lamp is generally more than 20 meters.

The above four lamp holders are called spotlights, which are generally composed of 400W high-pressure sodium lamps or metal halide lamps.

The function is centralized lighting, because urban intersections are relatively wide.

The street lamp with normal height can't meet the lighting requirements in terms of illuminance and lighting direction.

Therefore, this half-width medium and high pole lamp is used to enhance the lighting.

If the turntable intersection is used, the full-width medium and high pole lamp is generally used for lighting.
