What are the basic requirements for led solar street lights

1. Requirements for the installation of dual-arm LED street lights: The distance between the street lights installed above the motor vehicle lane and the ground is not less than 11.5 meters, and the lighting above the sidewalk is 8.5 meters away from the ground, and the two sides are arranged crossing each other at a distance of 50 meters. The power of the express road light source uses 120W LED street light, and the pedestrian road light source uses 80W LED street light. On the highway, a 12-meter high pole lamp is generally used, and the cantilever has a single pick and double pick, and a 400W high-pressure sodium lamp.

2. The pole material is made of high-quality Q235A steel (the silicon content of the steel is not higher than 0.04%). It is a tapered pole formed by bending. The pole is made of 4mm thick steel plate. The thickness of the pole does not include the thickness of the galvanized layer. The main pole of the light pole adopts a conical shape, the diameter of the small end is about 85mm, and the diameter of the large end is about 200mm. The lifting rods are all steel pipes with a diameter of 60mm. The length of the outside lifting is 1.6 meters for the motorway, the sidewalk is 1.2 meters, and the wall thickness is 3mm.

3. The surface of the light pole is smooth, and there should be no cracks, missing welding, continuous pores, undercuts, and inequality in any place. The linear error of the center line of the pole does not exceed 0.02% of the pole length, the pole body has no unevenness or traces, and there is no obvious defect in the appearance of the pole.

4. The lamp pole welding method is automatic sub-arc welding, ultrasonic flaw detection and inspection, which meets the requirements of welding GB11345 class II standard. The lamp pole socketing method is fixed by nails and top wires.

5. The surface of the led solar street light manufacturer is treated by a hot-dip galvanizing anticorrosive annealing furnace. The zinc layer is not less than 75 microns. The surface is practical and smooth, and the color is basically the same. After the hammer test, it will not peel or peel, and the galvanized life will not be less than 20 years.

6. LED solar street lamp manufacturers need to spray painted street light poles, the color and brand are operated according to requirements, the surface is smooth and smooth, the quality of the plastic layer is stable, does not fade, does not fall off, strong adhesion, strong UV resistance, and the service life should not be less than 20 years , Thickness ≥80um, in line with ASTMD339-83 standard.

Material classification

1. Iron light pole

At present, many domestic LED solar street light manufacturers use iron poles. After processing and molding, the exterior is painted with paint. The service life is about three to five years. Later, it will be replaced regularly depending on the impact of the environment.

2. Stainless steel light pole

Using stainless steel material, the service life is more than 3 times that of iron lamp poles (usually). The surface of the lamp pole is treated with hot-dip galvanizing, and the production cost is relatively increased. It is mainly used in parks, scenic spots, courtyards and other venues.

3. Aluminum pole

It is formed by aluminum alloy, which is lighter in weight than the first two, and has high strength. The protective film on the surface makes it very resistant to scribing and corrosion, which is more suitable for long-term use in harsh environments such as outdoors. Because of the high cost, they are generally exported to countries with good economic conditions, such as Europe and the United States.
