Professional manufacturer of LED lights: how to identify the light emitting diode ( 领导)

by:SUNFREE     2021-02-10
The emergence of the LED street lamp brought great changes to people's lives. LED street lamp which is a kind of based on semiconductor PN junction formation with a weak electricity can glowing efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. LED lights factory it is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long life, therefore, the LED street light will become the best choice of the road lighting energy saving reconstruction. From solar energy water heater to solar car to later street lamp, solar energy application not only solve the problem of human energy, but also protect the nature. LED lights factory it is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long life, therefore, the LED street light will become the best choice of the road lighting energy saving reconstruction. LED street lamp manufacturers LED lights because its widely for solar energy, and attention, and has wide development space. Led street lamp manufacturers use led street light can get rid of the control of the power supply and constraints, and avoid the instability of the ac power is not stable brightness and power failure, do not have to worry about difficulties caused by the low voltage power supply during peak hours. Use of solar energy as an energy source, can make full use of and use of solar energy, so people can enjoy light at any time. In this street lamp at night, life will become more rich and colorful, even in the night, it will also have enough light, this is the pursuit of a lot of people, it's not difficult to realize this dream, whenever it is convenient for using solar energy. With the popularity of led lights, how to choose and buy high quality led street light is particularly important. Many unscrupulous businessmen only care about their own interests, and ignore the quality of products, greatly damage the our industry in the image. How to choose the high quality of led street light is our responsibility and obligation. First of all, we must first understand the led street light manufacturer of led lamp holder, which is led lamp holder. Thin and thick shell is a factor, is the structure of the aluminum plate, aluminum plate, and constant current source. The quality of lamps and lanterns basically can be determined by the size and thickness of these things. The second question is whether the battery for energy storage battery. Now, many small companies to use the power as an energy storage battery, greatly harm the life span of the LED street lamp. Then investigate LED street light pole is hot dip galvanized or cold galvanizing, the difference between the hot dip galvanized and cold galvanizing on the incision, galvanizing is still on the incision, cold galvanized coating on the incision. Half of the lamp holder is 60, wall thickness is about 2. 8. The bottom is associated with height, with taper ratio, thickness of about 4. Hot dip galvanized light pole the general life of more than 20 years, cold galvanized light pole total life expectancy is about 1 year. LED street lamp manufacturers believe that as long as we can grasp the above points, we wouldn't have cheated when choosing LED street lamp. When we buy LED lights, we should know about the LED street lamp manufacturers of LED street lamp parts. Components of the more specific type. Mainly include the panels, solar battery, solar controller, light source, such as the corresponding parts. Therefore, when choosing a solar cell, also should consider the material, the color difference, the charging current, open circuit voltage, conversion efficiency and other factors. When choosing the battery, we should know the detailed type of battery, the discharge rate and working environment. When choosing the controller, of course, also want to know the waterproof performance. When buy, of course, also want to know the specific match.
