LED strip flickering may be caused by unstable power supply voltage. LED strips require stable voltage to work properly, and unstable power supply voltage can cause flickering. In this case, it is necessary to check the stability of the power supply and take corresponding measures, such as using a voltage stabilizer or adding a capacitor.

LED strip flickering may also be related to power supply current. LED strips require appropriate current to work properly, and too much or too little current can cause flickering. In this case, it is necessary to check whether the output current of the power supply meets the requirements of the LED strip and adjust the output current of the power supply.

Another possibility is the quality of the LED strip itself, such as poor contact between the light beads, which may cause flickering. In this case, it is necessary to check the quality of the LED strip and carry out corresponding repairs or replacements.

In summary, the causes of LED strip flickering may be unstable power supply voltage, too much or too little power supply current, and quality issues with the LED strip itself. To avoid LED strip flickering, it is necessary to check and adjust the output voltage and current of the power supply and check the quality of the LED strip. Attention should be paid to these issues during the use of LED strips, and timely maintenance and replacement should be carried out.
