What is the cause of the lights after the led fluorescent lights are turned off
The third one is the most common problem of power leakage which is the small current of the power supply or the uncontrollable control
The second the problem is less But the most easy to test leakage is chip Or a chip resistance capacitance are stored This can be got, through testing machine performance
This is the first problem of phosphor There are residual afterglow The same way as a luminous powder By light after light This in normal LED, it is not possible
