LED lamp is a kind of energy-saving, environmental protection, long life lighting products, more and more favored by consumers. However, sometimes we will find that the LED light will flicker during the use of the phenomenon, which not only affects the lighting effect, but also may cause damage to the eyes. So, what causes LED lights to flicker? How to fix it? Today, I will introduce the causes and solutions of LED light flashing failure.
LED blinks Cause of the fault
The main reasons for LED flashing failure are as follows:
The power supply is unstable. If the power supply voltage or current fluctuations are too large, or the power line contact is poor, it may cause the LED light to blink. In this case, you can check whether the power line is loose or broken, or replace a stable power supply.
The LED light does not match the driving power. If the parameters of the LED light and the drive power supply are inconsistent, for example, the rated power of the LED light is greater than the output power of the drive power supply, or the rated voltage of the LED light is less than the output voltage of the drive power supply, it may cause the LED light to blink. In this case, you can replace a driver power supply that matches the LED light.
LED bead or driver is damaged. If there is aging, short circuit, open circuit and other faults inside the LED lamp bead or driver, it may cause the LED light to blink. In this case, damaged LED beads or drivers can be replaced.
LED lights are subject to external interference. If there are strong electromagnetic fields, radio frequency signals, lightning and other interference sources around the LED light, it may cause the LED light to blink. In this case, you can stay away from the interference source, or increase shielding measures.
Solution to LED flashing fault
According to different reasons, we can use the following methods to solve the LED light flashing failure:
Check and repair power lines. If the power line is found to be loose, open, oxidation and other problems, you can tighten, weld, clean and other treatment in time to restore the normal smooth line.
Replace the appropriate drive power supply. If you find that the LED light does not match the drive power supply, you can choose a suitable drive power supply according to the parameters of the LED light, and pay attention to the correct connection.
Replace damaged LED beads or drivers. If you find signs of damage to LED beads or drivers, you can use tools such as a multimeter to detect and replace them in time.
Keep away from or shield interference sources. If you find that there are interference sources around the LED lamp, you can try to stay away from them, or add metal shielding between the LED lamp and the interference source.
Sum up
The above is the article I introduce to you about the LED light flashing fault solution, I hope to help you. The main causes of LED light flashing failure are power instability, LED light and drive power do not match, LED light beads or driver damage, LED light by external interference, etc., we can use different methods according to different reasons to solve, let the LED light to restore normal lighting function.
