Professional LED street light manufacturer: how to identify light-emitting diodes (LED)
The emergence of LED street lights has brought tremendous changes to people's lives. LED street light is a kind of high-efficiency solid-state light source formed by semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, the holes injected into the P zone and the electrons injected into the N zone are in After being diffused to the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. LED street lamp manufacturers are a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high light efficiency, and long life. Therefore, LED street lamps will become the best choice for energy-saving transformation of road lighting. From solar water heaters to solar cars and later street lights, the application of solar energy not only solves human energy problems, but also protects nature. LED street lamp manufacturers are a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high light efficiency, and long life. Therefore, LED street lamps will become the best choice for energy-saving transformation of road lighting. LED street lamps of LED street lamp manufacturers have received widespread attention because of their use of solar energy as energy source, and have a wide range of development space. LED street light manufacturers use LED street lights to get rid of the control and constraints on the power supply, avoid the unstable brightness and power failure caused by the unstable AC power supply, and do not have to worry about the power supply difficulties caused by low voltage during peak hours. Using solar energy as an energy source can make full use of and use solar energy so that people can enjoy light at any time. With such a street lamp at night, life will become more colorful. Even at night, it will have enough light. This is the pursuit of many people. It is not difficult to realize this dream. As long as it is convenient to use, solar energy.
With the popularity of led street lights, how to buy high-quality led street lights is particularly important. Many unscrupulous businessmen only care about their own interests and ignore product quality, which greatly damages the image of our industry in the eyes of the masses. How to choose high-quality led street lights is our responsibility and obligation.
First of all, we must first understand the led lamp holder of the led street light manufacturer, that is, the led lamp holder. The thin and thick shell is a factor, and the internal structure is aluminum base plate, aluminum plate and constant current source. The quality of the lamp can basically be determined by the size and thickness of these things.
The second question is whether the battery is a dedicated battery for energy storage. Nowadays, many small companies use starter power as energy storage battery, which greatly damages the life of LED street lights.
Then check whether the pole of the LED street light is hot-dip galvanized or cold-dip galvanized. The difference between hot-dip galvanizing and cold-dip galvanizing is on the incision. Half of the lamp holder is 60, and the wall thickness is about 2.8. The lower end is related to the height, has a cone ratio, and the wall thickness is about 4. The general life of hot-dip galvanized light poles is more than 20 years, and the total life of cold-dip galvanized light poles is about 1 year. LED street light manufacturers firmly believe that as long as we can master the above points, we will not be deceived when choosing LED street lights.
When we buy LED street lights, we should understand the LED street light parts of LED street light manufacturers. There are relatively many specific types of components. There are mainly battery panels, solar batteries, solar controllers, light sources and other corresponding components. Therefore, when choosing a solar cell, factors such as material, color difference, charging current, open circuit voltage, conversion efficiency, etc. should also be considered. When choosing a battery, we should understand the specific type, discharge rate and working environment of the battery. Of course, when choosing a controller, you must also understand the waterproof performance.
Of course, at the time of purchase, you must also understand the specific matching situation.
