The main function of street lamp holder is to support street lamps. It usually consists of two parts: the lamp post and the lamp arm. Lamp pole is the main part of street lamp holder, generally cylindrical or polygonal, made of steel or cast iron. The height and material of light poles depend on actual needs and environmental conditions, generally ranging from 3m to 12m. The bottom of the lamp pole is usually buried underground to increase stability. The lamp arm is the part connecting the lamp pole and the lamp, which is generally curved, and the angle and length can be adjusted as needed.
Street lamp holders not only support lamps, but also provide lighting effects. A number of lamps are usually installed on the lamppost, and the number and layout of the lamps can be adjusted as needed. The type and power of lamps depend on the actual needs and road conditions, such as high-pressure sodium lamps and LED lamps. The installation height and angle of lamps need to be adjusted according to the actual situation to achieve the best lighting effect.
In addition, the street lamp holder also plays a role in protecting wires and cables. There are usually wires and cables passing through the lamppost for power supply and signal transmission. The structural design of light pole can protect wires and cables from external environment, such as wind and rain, sunshine and so on. At the same time, there are grounding devices on the lamp poles to protect the street lamp system from natural disasters such as lightning strikes.
In a word, the street lamp bracket is an indispensable part of the street lamp system, which not only supports the lamps, but also provides the lighting effect and protects the wires. With the development of science and technology, the design and materials of street lamp holders are constantly innovating to adapt to different road conditions and environmental requirements and provide better lighting effect and use experience.
