How to judge the quality of led solar street lights with pole? We did a clearly investigation so that we can choose high-quality LED solar street light poles?
With green energy energy saving and emission reduction is getting more and more attention, Led solar street light are also widerly used in road lighting. The increase in the number of peer companies has also intensified the competition of solar street lights. In order to pursue profits, some companies began to cut corners on the supporting components used in solar street lights with poles.
First: first look at the plate of the LED solar street light pole.
Many unscrupulous manufacturers use substandard thickness of steel or non-standard steel to fill the good. High-quality steel can withstand more than twelve levels of natural wind, but will not produce shaking or deformation.
The quality of substandard manufacturers use non-standard steel, in order to reach acceptance will be sprayed several times to increase the thickness of the solar street light pole.
So to determine whether the quality of the pole is up to standard, it is actually very simple. If you find that the thickness of the pole to meet the standard, then you can test the weight of the pole, if the actual weight does not meet the standard.
then the possibility of spraying to increase the thickness exists. At this point you can determine whether the light pole is up to standard by hanging off the spray plastic with a blade.
Second: looking at the workmanship of the solar street light pole.
The production of light poles require that there is no leakage of welding, false welding phenomenon. Welding should be beautiful to ensure that the welding is secure and durable.
Third: look at the galvanization of the solar street light pole.
Legitimate manufacturers are using Q235 steel for the overall hotness of the way to ensure that the light pole will not rust or become rotten. But some manufacturers in order to reduce costs, often using cold galvanized way of processing light poles.
Although the light pole for cold galvanized will feel the light pole surface bright, but the thickness of the zinc layer is only a few tenths of the hot dip galvanized light pole, its anti-corrosion performance than hot galvanized is also far from. So if you are a purchaser of solar street lights, then this is something you have to pay attention to.
Finally: we must also look at the spraying treatment of the solar street light pole.
Before doing the spraying treatment again, be sure to polish the light pole again. So that the light pole for spraying is only uniform, more pure color. At the same time if the light pole to do the color separation requirements, must observe the color of the light pole at the color separation is clear, is not clear also belongs to substandard products.
And we need to know the general wall thickness of the solar street light pole.
Solar street light pole with how thick, usually depends on how high the pole, single-arm or double-arm lights, 2-4 meters of solar street lights on the general wall thickness of 2.5 cm, 4-8 meters of solar street lights on the general use of 2.5-3.0 cm, 8-15 solar street lights on the general use of 3.0-4.0 cm, this is only the general standard, specific but also according to the wind requirements are different, the light pole thickness is also different.
The commonly used light pole is a steel tapered pole, which is characterized by beautiful, strong, durable, and easy to make a variety of shapes, simple processing technology, high mechanical strength.
Commonly used tapered light pole cross-sectional shape are round, hexagonal, octagonal, etc., the taper is mostly 1:9-1:15, wall thickness according to the force of the pole is generally selected in 2.5-5mm.
Solar street light poles are used outdoors, in order to prevent the pole from rusting and corrosion and reduce the structural strength, the pole must be galvanized and sprayed with plastic.
Hot-dip galvanizing spraying is mainly a preventive measure against the causes of rust and corrosion. Hot-dip galvanizing spraying can avoid or mitigate the effects of humidity, high temperature, oxidation, chlorides and other factors. The commonly used methods are as follows.
1、Light pole hot-dip galvanizing: The process and method of dipping the pre-treated parts into the molten zinc solution to form zinc and zinc-iron alloy coating on its surface, with a zinc layer thickness of 65-90 um. The zinc layer of the galvanized parts should be uniform, smooth, free of burrs, dripping tumors and excess lumps, and the zinc layer should be firmly bonded to the steel pole, with no peeling and no bulging of the zinc layer.
2、Light pole plastic spraying treatment: hot dip galvanizing and then plastic spraying treatment, plastic spraying powder should be selected outdoor special powder, the coating shall not have flaking, cracking phenomenon. Plastic spraying treatment can be higher to improve the anti-corrosion performance of the steel pole, and greatly improve the beauty and decorative solar street light pole, the color can also have a variety of choices.
For example, 6m solar street light with pole parameters specifications.
1、Specification：Light source is 6 meters from the ground, the material of the pole is Q235 carbon steel.
2, technical requirements (in line with and not less than national standards).
①The light pole adopts conical single bent arm light pole, with bottom diameter 154mm and top diameter 60mm.
②The light pole adopts hot dipped galvanized internal and external surface corrosion treatment, in line with GB/T13912-92 standard, the galvanized surface should be smooth and beautiful. Provide galvanized test report. Galvanized thickness is not less than 85μm.
③Light pole wall thickness ≥4mm, light pole chassis thickness of 22mm.
④Welding surface without cracks, porosity, biting edge, not welded full defects.
The supplier shall ensure that the light pole meets the wind pressure requirements of Wutai County and ensure the normal use of the light pole.
⑤ Service life of 20 years or more.
⑥The width of weld seam is 4-9mm, and the height of weld seam is 0-3mm.
⑦The supplier shall carry out quality inspection of the products before they leave the factory, and carry out comprehensive inspection of the welding quality, dimensional deviation and surface quality.
If it is a 20m width road, it should be considered as a main road, so it needs to be bilaterally laid light before it can be. In addition, the lighting requirements of the road mainly include illumination requirements, illumination uniformity of two,
where the uniformity of the general to be above 0.3, the greater the uniformity, indicating that the solar street light of the light scattered more open, the better the lighting effect.
Therefore, we can assume a double row of symmetrical layout, the height of the street lamp pole is at least greater than 1/2 the width of the road, so the height of the pole to 10-12 meters; assume a 10-meter pole, the installation spacing of street lights is generally about 2 times the height of the pole, so the spacing of at least 30 meters;
then assume that the solar street lights have a 30-meter spacing, the height of the pole is 10 meters, the power of the solar street lights in this case should be more than 100W, in order to basically meet the lighting requirements of the main road.
Secondly, illumination and power are related to the installation height of the lamps. For solar street light, we hope that the larger the angle of illumination, the better, so that the uniformity will also be good, and can make the spacing of the poles larger, reducing the number of poles installed, saving costs.
Conclusion: Today Belinda intruduce some specicifications about led solar street light pole, hope I can give our clients some suggests which will help you to choose good quality led street light pole.
