With the advancement of science and technology, traditional street lights with high-pressure sodium lamps as street lamp heads have been gradually abandoned, and
LED street lights are sweeping in irresistibly. Even if the price of LED street lamps is higher than that of traditional street lamps, it still can't stop the progress of LED street lamps' popularization. When many people buy it, they often don't understand its parameters and analyze its characteristics, so they buy it from LED street lamp manufacturers at will. In fact, there are certain skills to buy LED street lights. Today, LED street light manufacturers teach you how to buy LED street lights correctly.
The
LED street light consists of a street light pole, an LED street light head and a basic cage. The basic cage is a rectangular parallelepiped welded by a screw according to the size of the flange of the street lamp base. This has no technical content and does not need to be said. We mainly talk about LED street lamp heads. The power of its common traditional models is between W and W, with beautiful appearance and reasonable price. The heat emitted by these powers is within the heat dissipation range of the internal radiator, so the quality is guaranteed. However, it is not recommended that you choose traditional LED street lamp heads larger than W, because the heat sink inside is not enough to dissipate the heat of the light source above W. It is recommended that you choose modular LED light sources.
The price of
LED street light varies greatly according to the quality of the product. You can neither choose the price that is too high (because the price of led lamp beads is now much lower, resulting in the overall price of led street light is much lower than before), nor can the price be too high. Cheap, because such LED street lamp lamps will use poor quality and very low lumen beads. In addition, the lamp housing is of poor quality and easily damaged. There are also some LED street lamp heads under W that do not require a radiator. It is misleading. Although the overall LED price can be reduced a lot, the lack of a radiator will cause the LED light source to have a large light decay in a short period of time, resulting in a short life span, and the street lamp will not light up. In severe cases, it will cause a short circuit in the LED street lamp. Therefore, you need to ask the LED street lamp manufacturer for the specific configuration parameters before purchasing.
Finally, choose the street light pole. The street light pole should be hot-dip galvanized as a whole. Don't use it if it is not the whole hot-dip galvanized. Because the anti-corrosion and rust resistance ability of hot-dip galvanizing will be enhanced, it can ensure that the street light pole will not rust for at least 15 years.
