How to Choose Light Pole of Solar Led Street Light?

As a new power of green and environmental protection, solar led street light poles are a trend of development in recent years. Making full use of solar energy resources to provide electricity is of positive significance to alleviating the tension of power. Solar led street lights are powered by solar energy. Except for rainy days, it will generate a small part of the electricity bill when converted to city power. The operating cost is almost zero. The entire system is automatically controlled without human intervention. Not only is the operating cost low, the installation of solar led street lights is simple and convenient. There is no need to lay cables and many other basic projects like ordinary street lights. It only needs to have a base to fix it. All the wiring and control parts are placed in the lamp holder. However, solar led street lights are not small expenditures. Although this is a project that can bring long-term benefits, when buying street lights, we still have to try our best to choose a high performance one.

Solar led street lights are composed of batteries, solar panels, light sources, controllers, etc. When choosing solar led street lights, people tend to pay attention to the quality and capacity of these components, while ignoring the poles. On the surface, light poles only play a role in supporting street lights. In fact, the selection of street lights pole is also very particular. For different roads and different environments, the size, height, and material of the light poles are different. Let's take a look at how to choose solar street light poles.

1. The height requirements of solar led street light poles

The height of the pole determines the illuminance of the street lamp. Generally speaking, we need to survey and measure different environments, and then determine the height according to the brightness of the LED light source and the width of the road. For example, the height of one-sided street lamp ≥ the width of the road, and the height of two-sided symmetrical street lamp = half the width of the road . Street lights arranged in zigzag on both sides should have a height of at least 70% of the width of the road, so as to bring the best lighting effect. In addition, the trees and buildings around the road can't cover the solar panels, so the height of the solar led street light pole can't be chosen at will, and it is unreasonable to be too high or too short. Generally, 3-4m light poles are suitable for rural roads, and 5-7m solar led street light poles are used for dual-lane country roads. In addition, the traffic flow on the road must also be taken into consideration. 

2. Material requirements for light poles

The material of the solar led street light pole will directly affect its service life. Nowadays, the more common light poles are rolled from Q230 steel. The corrosion resistance of this material itself is really not very good, so the surface will be galvanized to enhance the corrosion resistance of the light pole. For example, hot-dip galvanizing or cold-dip galvanizing. Relatively speaking, the anti-corrosion performance of the hot-dip galvanizing light pole is better. Therefore, it is recommended to choose the light pole treated in this way when purchasing. In addition, some of the solar led street light poles that are often seen now also have surfaces that are stainless steel or anodized. The corrosion resistance of these two materials is also particularly excellent. However, these two types of light poles are more expensive. Users can choose according to their own budget.

3. Requirements for wall thickness of solar led street light poles

In addition to the above two aspects as the focus of consideration, there are also some details that can't be ignored, such as the wall thickness of the light pole, whether the light pole has sufficient wind resistance and sufficient load-bearing capacity. These factors all affect the service life of solar street lamps, so the wall thickness should be determined according to the specific scene of solar street lamp installation when choosing. For example, 2~4m street lights must have a wall thickness of at least 2.5cm, 4~9m street lights must have a wall thickness of 4~4.5cm, and 8~15m high street lights must have a wall thickness of at least 6cm. The area where there is always strong wind, so the wall thickness value is a bit larger.

We must ensure safety when choosing light poles. For every street lamp, the pole height setting is reasonable, too high or too low will affect its use efficiency. Part of this standard is a rigid requirement of the industry, and part of it is accumulated by solar led street light manufactuers based on their years of production experience. Usually, different street lamp pole heights are designed according to the width of the road, so as to maximize the lighting effect. Therefore, it is very important to choose a reliable solar street light manufacturer. Experienced solar street light manufacturers can design a very reasonable solar street light configuration according to the customer's budget.
