What should I do if the panel light is flickering?
-
The switch is on and flashing, which can be seen in:
LED driver quality issues, grid voltage is too low, and the driver and LED luminaire are mismatched, resulting in a drive hiccup output (periodic frequent start-up).
The LED lamp beads have serious light decay and have been damaged.
The switch is off and flashing (shimmering) is seen in:
The mA-level leakage current formed by the distributed capacitance of the indoor wiring that has existed for a long time is manifested when it encounters an mA-level current that emits a low-light LED.

It may be caused by the weak power supply, or it may be that the small filament inside is broken.
-
LED constant current power supply.
What causes the LED light to flicker? Respectfully.
As for the LED light flashing, whether it is flashing after opening or flashing after closing, one, flashing after opening indicates that the power supply circuit of the LED light is missing, two, the flickering after the collapse is caused by the induction electricity in the power circuit of the LED lamp, and third, this is determined by the characteristics of the LED lamp, "high power, low power consumption, high brightness".
LED driver quality issues, grid voltage is too low, and the driver and LED luminaire are mismatched, resulting in a drive hiccup output (periodic frequent start-up). >>>More
It is generally caused by the instability of the indoor voltage, check whether the electrical appliances at home are turned on too much.
There are only two reasons for the sound of the lamp, one is the hum of the transformer, and the other is the contact ignition caused by the poor contact of a node, and the others will not make a sound.
This can't be repaired, if you have to repair it, then go to a treasure to buy a universal drive, and then see if there is the same light board to change.
If you use it, it is like destroying an ordinary light bulb. >>>More
