How to check and repair the failure of solar street lights

Solar street lights are more complex than traditional street lights, so it is more cumbersome to repair once failures occur. But fortunately, solar street lights do not have continuous wires, which saves a huge search and repair project. Before repairing the solar street light, it is necessary to confirm which part is damaged, that is, the preliminary inspection work. Solar street lights generally consist of the following parts: solar panels, lamps, batteries, there are controllers and LED light sources in the lamps, and the controller has the highest probability of failure. The following solar street lamp maintenance company and manufacturer Chang Hui Lighting sorted out some common faults and repair methods of solar street lamps: [The whole lamp does not turn on] [Solar street lamps are used for outdoor lighting, often encounter high temperature and rain, low temperature rain and snow, and The solar street light controller is usually installed in the light pole, which is easy to cause the short-circuit phenomenon of water entering the controller. First observe whether there are water traces and rust on the terminal of the controller. If it is very likely that the controller is damaged and no battery voltage measurement is performed, such as a 12V solar street lamp power supply system, the battery voltage is lower than 10.8V, the battery is no longer stored , Needs to be replaced. Then check whether there is voltage and current output under normal working conditions of the folding sky battery board. If the battery board is damaged, replace the battery board. None of the above is a problem, you should check the light source and only supply power to the light source to see if it is on. If it does not light up, replace the light source. [The lamp head flashes]. The cause of this failure is poor line contact, battery power loss, and serious decline in power storage. If the line is okay, replace the battery. [The lighting time is short, and the duration of rainy days is short] It is usually caused by a decrease in the storage capacity of the battery and sufficient power storage. Just replace a reasonable battery. [Solar street lights are not fully lit] Many solar street lights use dot-matrix LED light sources. In addition to the quality of the LED light source itself, some weak soldering of the lamp beads will cause this situation. The solution is to replace the corresponding lamp beads, weld firmly or replace the entire street lamp head. Of course, in addition to the above points, we should pay more attention to whether the product quality is qualified or not when purchasing and installing solar street lights. Unqualified products often fail to reach the expected lifespan, and the final cost of replacement or repair in the middle is higher. Therefore, Changhui Lighting recommends that you do not blindly seek cheap while ignoring the core factor of the product-quality! To
