LED street lights for late pedestrians to illuminate the way home, even tired pedestrians looking at the light, heart will have a warm feeling. But if the light of the street lamp is no longer so docile, turn to be like the crazy shining in the horror movie, the warm feeling before trust will come to naught. Today Xiaobian to talk about LED lighting street lights flashing causes and treatment methods:

1, LED lamp beads and LED drive power does not match, normal single foot 1W lamp beads accept current: 280-300mA, voltage :3.0-3.4V, if the lamp chip is not full power will form the phenomenon of light strobe light source, the current is too high to accept the lamp bead on a bright off, severe phenomenon will put the lamp bead built-in gold or copper wire burned off, resulting in lamp bead not bright.

2. It may be that the drive power is broken. As long as you replace another good drive power, it will not flash.

3. If the drive has overtemperature protection function, and the heat dissipation performance of the LED street lamp material can not meet the requirements, the drive overtemperature protection will start to work and there will be a flash out phenomenon, such as: 20W projection lamp shell used to install 30W lamps and lanterns, heat dissipation will not be done well.

4. The LED street lamp is flooded with water, which also shows the phenomenon of stroboscopic flashing. The result is that the flashing is not bright. The lamp bead and drive are broken. If the drive waterproof is done well, it will only break the lamp bead and replace the light source.

The key to see the flashing problem of LED street lights lies in the driving power supply. Under normal conditions, only the replacement of the driving power supply is needed to deal with the shining problem of street lights, and the operation is still relatively easy. If we find a certain section of street lights flashing phenomenon, we can inform the municipal part to let them quickly repair, do not scare the children.
