How to maintain and maintain led street lights

After the LED street light is installed and used for a period of time, it is necessary to replace the battery, battery, controller and other products. LED street lamp manufacturers are a kind of 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 a good choice for energy-saving transformation of 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. All major components have cycle life. 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. Under normal circumstances, a reasonably configured LED street light can be used for 8-10 years. Some engineers and government departments like to buy LED street lights at a very low price because LED street light manufacturers get it. The limited product capital, product quality and configuration may be very low, so it cannot be used normally in less than a year, and some manufacturers do not have after-sales service in order to make money quickly, so if you want to turn on the lights, you need to find other manufacturers to repair and maintain. In the past, the after-sales service of Aide Street Lamp was very troublesome.
Currently, many such customer orders have been received. Some of them cannot find a manufacturer within 5 years. In some cases, the manufacturer does not care about sales (after the manufacturer does not give free sales, customers pay for it and do not trust them, so they find other manufacturers). In short, whether it is the configuration of the quality itself or the end of the life of the components, we, as a professional and leading street lamp manufacturer, have received more and more maintenance problems.
LED street lights generally only need to replace the controller and battery, but some street lights were installed earlier (such as the LED street lights installed before 2013). The light source power is relatively large, and it has the characteristics of low light source efficiency and high self-loss, so The battery that needs to be replaced is also relatively large, and the replacement of the battery and the controller is more expensive than the new system, so the comparison is based on the price and the product. We recommend that customers change the light source, because the technology is developing and the products are being updated. The light efficiency of the LED light source has been greatly improved. The light efficiency of the LED light source is greater than in previous years. Of course, the current 30W light source can be replaced by 15W. Of course, by the official The number of beads of the high-power LED lamp produced by the manufacturer is 150 to 160 lumens, and the pearlescent efficiency of the SMD lamp on the market is low, and the quality is relatively poor. Therefore, it is necessary to find a regular and reliable manufacturer to maintain LED street lights. The quality of the LED street light system is more stable, the price has not increased, and the brightness of the LED light source is much higher than before.
Solar cell modules are now mostly made of crystalline silicon, with a good low-light detection system, and comply with IEC61215 and the second level of electrical protection standards. The surface of the solar cell module adopts a reflective film and a highly transparent glass design, which greatly improves the ability of the solar cell module to receive light energy and increases the ability of electric energy conversion. There are corresponding holes on both sides of the peripheral frame of the solar integrated street light, which can be easily installed in the corresponding system structure. The battery pack usually has a standard MC connector and a one-meter cable. There are three diodes in the junction box, which can effectively reduce the power loss of the internal system of the solar module. Solar panel components can be used for up to 25 years and usually do not need to be replaced.
The controller is an important core of led street lights, solar power generation systems and solar car batteries.
