Something You Should Know About Street Lights

As an important part of urban lighting, street lights not only provide lighting for pedestrians and vehicles at night to ensure safety, but also beautify the urban environment. Basic knowledge about street lights can mainly be understood from the following aspects:


Traditional street lights: including high-pressure sodium lamps, metal halide lamps, etc., are characterized by high brightness, but high energy consumption and relatively short life.
LED street lights: Street lights using light-emitting diodes as the light source have the advantages of energy saving, environmental protection, long life, high light efficiency, and low maintenance costs. They are currently a popular type of street lights.
Solar Street Lights: Street lights that are charged by solar panels and powered by batteries at night. They are suitable for installation in areas far away from urban power grids or in areas with unstable power grids.


Light source: It is the core component of street lamps. Common ones include LED lamps, high-pressure sodium lamps, etc.
Light pole: The structure that supports the light source. The material is usually steel, aluminum alloy, etc., and it needs to have sufficient strength and stability.
Luminaire: A housing that surrounds a light source to protect it and improve light distribution.
Controller: Especially in LED and solar street lights, it is used to adjust the brightness of the light and the function of automatically turning the light on and off at night.
Batteries (solar street lights): store the energy collected through solar panels during the day and provide power at night.

Installation and layout:

Height: Determined according to the use place and lighting requirements of the Street Light. Common ones are 4 meters, 6 meters, 8 meters, etc.
Spacing: It depends on the height of the Street Lamp, the type of light source and the width of the road. The purpose is to ensure uniform lighting of the road and avoid the "zebra crossing" phenomenon of alternating light and dark.
Location: Generally installed on both sides of the road or on the central divider of the road, the safety of pedestrians and vehicles and the lighting effect must be taken into consideration.

Light pollution control:

Avoid excessive lighting and unnecessary light radiation, choose appropriate light sources and lamp designs, and reduce the impact on the surrounding environment and residents' lives.

Maintenance and economy:

Regular inspection and maintenance can extend the service life of street lights and reduce failure rates.
When selecting the type of street light, initial investment costs and operation and maintenance costs, as well as energy efficiency and environmental protection requirements, should be comprehensively considered.
Understanding these basic knowledge will help you make more reasonable choices and decisions when planning, designing and maintaining urban lighting systems.
