Service Life Of LED Street Lamp Posts

As we all know, the cast iron street lamp post has high strength and durability, and has a long service life. Under normal outdoor conditions, after reasonable installation and maintenance, the service life can reach more than 20 years.

Environmental and maintenance factors affecting the life of outdoor lamp poles

In addition to the material, the service life of street lamp poles is also affected by the environment and the use and maintenance.

1. Environmental factors:

LED street lamp post is located outdoors and is eroded by natural environments such as sun, rain, wind, snow and pressure for a long time. These harsh environmental conditions will cause corrosion and aging of the poles, thereby shortening their service life. Therefore, when selecting the material of the lamp pole, its corrosion resistance and weather resistance should be fully considered.

2. Maintenance factors:

Proper installation and regular maintenance are essential to extend the service life of street lamp poles. Improper installation, such as unstable foundation and crooked pole body, will cause uneven force on the lamp pole, thereby shortening its life. Regular maintenance can timely discover and deal with potential safety hazards and ensure the normal use of the lamp pole.

Phoebus LED street lamp post requires a series of anti-corrosion treatments, which are achieved through hot-dip galvanizing and plastic spraying technology. The thickness of the zinc coating reaches more than 85um, and the thickness of the plastic coating reaches more than 100um, with a smooth surface and high hardness.

LED street lamp post hot-dip galvanizing process

‌Acid pickling and rust removal‌: remove the oxide layer and impurities on the surface of the street lamp pole.

‌Water washing and cleaning‌: clean the residual acid ions.

‌Plating treatment‌: enhance the adhesion of zinc liquid.

‌Drying plated parts‌: ensure that the surface of the street lamp pole is dry.

‌Zinc dipping operation‌: zinc liquid forms an iron-zinc alloy layer with the surface of the lamp pole at high temperature.

‌Cooling and curing‌: reduce the temperature and inhibit the reaction of the coating with air.

‌Medical treatment‌: enhance the anti-corrosion performance of the street lamp pole.

‌Cleaning and polishing‌: remove residues and polish the smooth surface.

LED street lamp post plastic spraying process

Pretreatment: first, the street lamp pole should be cleaned, degreased and derusted to ensure that the surface is clean and free of impurities.

Electrostatic spraying: place plastic powder in the spray gun, and form an electric field between the spray gun and the metal parts through a high-voltage electrostatic generator. The plastic powder particles are fully charged under the action of the electric field, and fly to the metal surface along the direction of the electric field and are evenly adsorbed on it.

Curing: The sprayed metal parts are sent to a high-temperature oven for baking. Under the action of high temperature, the plastic powder particles melt and level to form a dense coating. Subsequently, the coating quickly cools and solidifies, and is tightly bonded to the metal surface.

Inspection: Use a film thickness meter to measure and visually inspect the appearance, paying attention to the integrity of the coating at the flange connection surface and weld.
