What are the possible failures of LED street lights? How to prevent it?
With the development of LED technology in the lighting industry, the high-pressure sodium light source used in road lights has gradually been eliminated. LED light sources are widely used in outdoor road lighting because of their high brightness, low energy consumption, and power-saving advantages. Many people now prefer to use LED street lights because they have many advantages. But we know that no matter what kind of street lights may encounter some failures, what should we do when we encounter these failures? How to prevent it?
Trouble 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 inside 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, then it is a problem with the drive power supply. The driving power supply controls the voltage and current of the LED street lamp. 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 Moso or MEAN WELL. The probability of failure of this drive power supply is smaller than that of other power supplies.
Fault two, the brightness of the LED street lamp becomes dim
The dimming of LED street lights may be due to poor quality of the LED chip inside the light source, which may cause large light attenuation. 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 the burning of some lamp beads inside the light source. In this case, we have to consider the problem of the capacitance or resistance of the LED street lamp.
Trouble 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 V relay, connect the coil and the light source in series, and the problem that the LED street light does not light can be solved.
