Yufai: What are the possible failures of solar power street lamp？

With the development of solar power street lamp technology in the lighting industry, the high-pressure sodium light source used in street lamps has gradually been eliminated. Solar light sources are widely used in outdoor road lighting because of their high brightness, low energy consumption, and power-saving advantages. Now many companies and businesses are more willing to use solar power street lamps because they do have many advantages, but we know that no matter what For what reason, street lights may encounter some failures. What should we do when we encounter these failures?

Fault 1: The street light does not light up

The problem of street lights not turning on is really worrying. First of all, we have to check the circuit in the 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, because The driving power supply controls the voltage and current of the street lamp. If the voltage and current are too large or too small, the street lamp will not light up. At this time, we should consider replacing a new driving power supply and try to choose a brand power supply to reduce the failure of this driving power supply. The odds.

Fault 2: The brightness of the street lamp becomes dim

The dimming of the street light may be due to the poor quality of the chip inside the light source, which leads to large light attenuation. Therefore, when we choose street lights, we try our best to require solar street light suppliers to use imported chips. In addition, the dimming of the street lamp brightness may also be caused by some lamp beads inside the light source burned out. In this case, we should consider the problem of street lamp capacitance or resistance.

Fault 3: Street lights flash after they are turned off

If the light source is still flickering after the solar power street lamp is turned off, this situation may be caused by the self-inductance current generated by the 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 street lamp does not turn on. It can be solved easily.
