Although LED street light technology is now very mature. However, we know that no matter what kind of street lights may encounter some failures, what kind of failures may occur in the use of LED street lights? What should we do when we encounter these failures? How to prevent it?
Fault 1: LED street light does not light up
There are many reasons why the LED street light does not light up, and you need to check it first.
1. All LEDs are off
1). If the cause is: the mains protection switch has tripped, just turn it on. If it doesn’t light up even after it’s powered on, it’s usually the LED drive power failure.
2) The LED street lamp power supply is a waterproof and sealed power supply. If it is broken, it will be replaced. The imperfect power supply protection function will directly affect the quality of the LED street lamp.
2. There are several possibilities for only part of the damage:
1). If the LED street lamp power supply is multi-channel constant output, which group may be broken
2) The LED chip is not good, or the LED street lamp heat dissipation is not good, causing the LED chip to burn out.
Fault 2: The brightness of the LED street lamp becomes dim
The dimming of the brightness of the LED street lamp may result in 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 burned out. In this case, we have to consider the problem of the capacitance or resistance of the LED street lamp.
Fault 3: 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.
Since LED street lights may encounter such and other failures, it is costly to eliminate and maintain, our best practice is to take precautions. Try to find more powerful and reliable manufacturers to buy. Determine the quality of the product before buying, focusing on the brand of each component, product inspection certificates and reports, etc. CHZ is a manufacturer of high-quality LED outdoor lighting fixtures, with excellent quality and first-class service, which can solve your worries to the greatest extent.
