What are the possible failures of LED street lights? How to prevent it?

With the development of LED technology in the lighting industry, high-pressure sodium light sources used in road lights have gradually been eliminated. LED light sources are widely used in outdoor road lighting because of their high brightness, low energy consumption, and power saving lamps. Many people are now more willing to use LED street lights, because it has many advantages. But we know that no matter what kind of street lights are likely to encounter some failures, what should we do when we encounter these failures? How to prevent it?

Fault 1: LED street light does not light up

The problem of LED street lights not turning on is really worrying, so how can we prevent and solve this problem? First of all, we have to check the circuit in the LED street lamp to see if the circuit is short-circuited or the contact is not bright. If no problem is found after the circuit inspection, it is a problem with the drive power supply. The driving power supply controls the voltage and current of the LED street lights. If the voltage and current are too large or too small, the LED street lamp will not light up. At this time, we should replace a new drive power supply, try to choose a brand power supply, such as brand MEAN WELL, the probability of failure of this drive power supply is smaller than other power supplies.

Fault two, the brightness of the LED street lights becomes dim

 

The dimming of the brightness of the LED street lamp may cause large light attenuation due to the poor quality of the LED chip inside the light source. When choosing LED street lamps, we try to require street lamp manufacturers to use imported LED chips. In addition, the dimming of the brightness of the LED street lamp may also be caused by some lamp beads inside the light source burning out. In this case, we have to consider the problem of the capacitance or resistance of the LED street lamp.

Fault three, LED street light flashes after turning off

If the light source is still flickering after the LED street lamp is turned off, this situation may be caused by the self-inductance current generated by the LED street lamp itself. To solve this problem, you need to buy a 220V relay, connect the coil and the light source in series, and the problem that the LED street light does not light can be solved.
