The led street light is composed of five main components: lamp post, light source, battery, solar panel and controller. LED street lamp manufacturer is 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 road lighting. LED street light is a high-efficiency solid-state light source formed based on a 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 area and the electrons injected into the N area are in After being diffused to the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. It also requires accessories such as cages, wires and solar panel supports.

To know whether the quality of led street lights is good, we can judge the led street lights according to the led lamp posts, panels and batteries, as well as their light source and controller light components. The first LED street light pole LED street light pole is divided into hot-dip galvanized and cold-dip galvanized. Is it better to use hot-dip galvanizing or cold-dip galvanizing for LED street light poles? Anti-corrosion: hot-dip galvanizing is dozens of times that of cold-dip galvanizing; hot-dip galvanizing is to immerse the entire LED light pole in a hot-dip galvanizing solution of 450-480 degrees, and cold-dip galvanizing is to electroplate the light pole at room temperature; Thickness of galvanized layer: the thickness of hot-dip galvanized LED lamp is much greater than that of cold-dip galvanized; appearance finish: cold-dip galvanized pole is smoother and more beautiful than hot-dip galvanized pole; adhesion: cold-dip galvanized pole is better than hot-dip galvanized The adhesion is small. The lead light pole must use hot-dip galvanized molded products. Although the price of the entire hot-dip galvanized molded LED light pole is much higher than that of the cold galvanized light pole, it is cost-effective in terms of practical application and service life. Second: the quality of solar panels led street lights solar panels can be seen with the naked eye. We can check the tightness of the panel, process details, as well as the thickness of the tempered glass and the quality of the aluminum frame, but the power of the solar panel can only be tested by the instrument. In order to save costs, some unscrupulous merchants will use inferior steel glass and thin aluminum frames as fixing devices for solar panels. This street lamp solar panel is easy to be damaged during transportation, and it is not easy to encounter hail and rain during use, so be careful when choosing solar panels. There are also bad companies that use batteries poorly, low conversion efficiency, poor power generation and quality, and there is a possibility that the batteries will have no voltage after a period of use. We must pay attention to these when buying solar panels. Third: Battery LED (Light Emitting Diode) street lamp battery needs to choose high-quality lithium battery or gel battery. A battery with a certain capacity has a corresponding weight, which can be used to weigh the LED (light emitting diode) street lamp battery. The weight is poor. Too big to choose. The surface of the battery has any manufacturer's name and capacity label. Fourth: LED light source LED street lamp uses LED lamp bead luminous efficiency is very important. Although some LED lamp beads can reach a certain wattage, they often fail to achieve luminous efficiency. When choosing, you should choose LED lamp beads, good lamp beads can improve light efficiency, reduce light decay, and have high color rendering.
