I believe everyone is familiar with LED street lights, and you can see LED street lights standing next to the road on all roads. The reason why LED lights are slowly occupying the lighting market is that they have the characteristics of large brightness, low energy consumption and long life. Many people are willing to buy LED street lights because they are really advantageous! Of course, we also hope to buy LED street lights for a long time, but no matter what kind of street lights, there will be some problems. What are the problems? How to prevent these problems from happening? Next, let the LED street lamp manufacturer answer it for you! 1. The problem that the LED street light does not turn on 　　 The problem that the LED street light does not turn on is really worrying, so how should we solve this problem? First, we must check the circuit first, because many times the LED street light does not turn on. It may be that the circuit is malfunctioning. If there is no problem with the circuit after checking, it should be a problem with the driver. The driver controls the current and voltage. If the current and voltage are too large or too small, the street light cannot be turned on normally. If a driver problem is detected, a new driver needs to be purchased for replacement. 2. The problem of dimming the brightness of LED street lamps 　　 I believe anyone who has seen the lamp holder of LED street lamps knows that the lamp holder is generally composed of lamp beads. The lamp beads are in a string. If one of the lamp beads in this string is burnt, the other lamp beads in this string will not light up. If this entire string of lamp beads is burned, the entire lamp cap will not light up. We can see the burnt lamp beads from the appearance, and the dimming brightness may also be caused by individual lamp beads being burned. Of course, if one lamp bead in each string of lamp beads is burned, it is necessary to consider whether it is a problem of capacitance or resistance. 3. The problem of LED street lights flickering after turning off 　　 If the head of the LED street lights still flashes after turning off the lights, the first thing we have to consider is the problem of the wiring, and there may be a problem with the neutral line of the switch control. If this is the case, we must deal with it in time to avoid danger. If no problem is found after the circuit inspection, it is most likely the self-inductance current generated by the LED street light itself. To solve this problem, we have to buy a 220V relay and connect the coil in series with the light to solve this problem. How to prevent some problems? 1. Check the charging and discharging of the battery: Many LED street lights are equipped with a battery. In order to keep the battery used for a longer time, we also need to check it frequently. The main thing is to check the discharge of the battery to see if the battery has normal charging and discharging conditions. Sometimes we also need to check the electrode or wiring of the LED street light for signs of corrosion. If there is any, we should deal with it as soon as possible to avoid bigger problems.　2. Check the body of the LED street lamp: The body of the LED street lamp is also a very important part. It is necessary to check whether the lamp body is seriously damaged or leaking. No matter what kind of situation occurs, we must deal with it as soon as possible, especially the leakage phenomenon, we must deal with it as soon as possible to avoid electric shock accidents. 3. Check the condition of the controller: The LED street light is exposed to wind and rain outdoors, so whenever there is a strong wind and heavy rain, we must check whether the LED street light controller is damaged or whether there is water ingress. There are a small number of such cases, but once they are discovered, they must be dealt with in time. Only regular inspections can ensure that the LED street lights can be used for a longer time.
