The common troubleshooting of LED street light?

LED street lights believe that everyone is already familiar with it, because it has the characteristics of high brightness, low energy consumption and long life, so now it is slowly occupying the lighting market. Many people are willing to buy LED street lights because LED street lights are really advantageous! Buy LED street lights, of course, we also hope to be able to use for a long time, but no matter what kind of street lights, there will be some problems. What are the common problems with LED street lights, and how should we solve them? Let's take a look at them:

1, the LED street light cannot brighten

The problem that the LED street light is not bright is really very embarrassing. How should we solve this problem? First, we must first check the circuit, because many times the LED street light is not bright because of the 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 able to light up normally. If it is detected that the drive is a problem, you need to purchase a new drive to replace it.

2, LED street light brightness is dark

I believe that anyone who sees the LED street lamp head knows that the lamp head is usually composed 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.
