LED street lights believe that everyone is already familiar with them, and LED street lights standing on the roads can be seen on all roads. LED lights slowly occupy the lighting market because of its high brightness, low energy consumption and long life. Many people are willing to buy LED street lights because LED street lights are really advantageous! We also hope to use LED street lights for a long time, but no matter what kind of street lamps, there will be some problems. There are those problems, how to prevent these problems from happening? How do we repair led street lights?
1, the LED street light is not bright
The problem that LED street light is not bright is really very embarrassing. How should we solve this problem? First of all, we must first check the circuit, because many times LED street light is not bright, it may be a circuit failure. If there is no problem with the circuit after checking, it should be a problem with the drive.
The driver controls the current and voltage. If the current, voltage is too large or too small, the street light will not be bright. If it is detected that it is a problem with the drive, you need to purchase a new drive to replace it.
2, LED street light brightness is dark
I believe that anyone who has seen LED street lamp heads knows that the lamp heads are usually made up of lamp beads. The lamp beads are a string of strings. If one of the lamp beads in the string is burned, the other beads of the string will not light up. If the whole string of beads is burned, the entire lamp will not light up.
The burnt lamp beads are visible in appearance, and the darkening of the light may also result in individual lamp beads being burned. Of course, if a lamp bead is burned on each string of lamps, consider whether it is a capacitor or a resistor.
3. The problem that the LED street light flashes after turning off the light
After the LED street light is turned off and the lamp head is still flashing, the first thing we should consider is the line problem. It may be that the zero line of the switch control has a problem. If this is the case, we must deal with it in time to avoid danger. If no problem is found after the circuit is checked, it is likely to be the self-inductive current generated by the LED street lamp itself. To solve this problem, we have to buy a 220V relay, the coil and the electric light in series, you can solve this problem.
