Welcome Qiri Photoelectric Technology (Dongguan) Co., Ltd
The commonly used antirust technology for LED street lamp poles is hot-rolled steel plate+hot-dip galvanizing+plastic spraying. LED street lamp manufacturer is a solid cold light source, which has the characteristics of environmental protection, pollution-free, low power consumption, high luminous efficiency, long life, etc. Therefore, LED street lamp will become the choice of road lighting energy-saving transformation. LED street lamp is an efficient solid state light source based on semiconductor PN junction, which can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, holes injected into the P area and electrons injected into the N area diffuse to the active area and emit photons after radiation recombination, directly converting electrical energy into light energy. After the lamp pole is galvanized and sprayed with plastic, its theoretical life is 15-20 years, that is, the paint of the street lamp will not fade or rust for at least 15 years, but can this effect be achieved in actual use?
After hot-dip galvanizing, the LED street lamp pole is almost free of rust. LED street lamp is an efficient solid state light source based on semiconductor PN junction, which can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, holes injected into the P area and electrons injected into the N area diffuse to the active area and emit photons after radiation recombination, directly converting electrical energy into light energy. If some poor manufacturers use cold galvanizing or galvanized sheet to do it, another factor affecting the life of street lamps is paint. After the LED street lamp pole is galvanized, an anti-corrosion coating process - spraying is carried out. The plastic powder used is outdoor plastic powder. Outdoor plastic powder has the characteristics of high hardness and strong adhesion. Although the appearance and anti-corrosion effect of the lamp post have been further improved after spraying treatment, it is found after actual use that the service life of the plastic powder is less than 10 years, let alone 15-20 years, in order to obtain better outdoor highlights. For the plastic powder, the surface of the painted lamp pole is bright and smooth, but after three years of outdoor use, the luster of the LED lamp pole surface will gradually fade, and then change color and paint off. This is a good plastic powder. The plastic powder with poor quality will be completely deformed in less than one year, and discoloration and paint stripping will occur in three to five years.
The invention relates to a method for prolonging the service life of street lamp coating, which can maintain the initial color for a long time without discoloration and chalking. If galvanization is to prevent rust, spray forming is to beautify, rust proof and beautify, and then adding a layer of protective film can be called perfect. The weather resistance of outdoor powder is very poor. If it can be packaged with an exterior wall coating with super weather resistance, its true color can be kept for a long time, but this exterior coating is not easy to find. It is a "fluorocarbon coating". The fluorocarbon coating has excellent anti-corrosion performance, maintenance free, strong adhesion, good weather resistance and other characteristics. The fluorocarbon coating on the plastic powder outer layer of LED street light pole can play a good role in protection. It is no problem to keep the luster of exterior wall paint on its surface for more than 10 years.
The service life of led street lamp pole has exceeded ten years. It will be beneficial for life, once and for all, with correct and high-quality technology.
