The flashing of the LED light box may be caused by the following reasons:
Internal light box tube problem: If the internal LED lamp bead or lamp tube contact is poor, this will lead to current instability, resulting in flashing.
Driver power failure: If there is a problem with the driver power of the LED light box, such as the output voltage is unstable, it will also cause the LED light in the light box to blink. This may be due to capacitor failure inside the power supply, driver chip failure, or other components aging.
Lamp beads do not match the power supply: If the specifications of the LED lamp beads do not match the drive power supply, such as the current and voltage supply are not suitable, the lamp beads may flash due to too high current.
Heat dissipation problem: LED will generate heat when working, if the heat dissipation design of the light box is not good, resulting in overheating of the LED, may cause the driver's protection mechanism to start, which is manifested as flashing.
Voltage instability: Fluctuations in the external supply voltage may also cause the LED light box to flicker, especially in environments where the voltage changes frequently.
Line connection problems: Poor contact of the power cord, or loose wiring inside the light box, can lead to unstable current supply, causing flickering.
To solve such problems, it is usually necessary to check whether the power drive is normal, whether the lamp beads are damaged, and whether the line connection is firm. If you have the knowledge, you can try to replace the driver, lamp bead or repair the line connection; Otherwise, it is recommended to contact a professional for repair.
