How can I remedy the afterglow of LED lamps?
How can I remedy the afterglow of LED lamps? We are regularly asked why some LED lights still glow after use and sometimes even flash, while the switch is switched off. And they are also asked how this is possible and how they can be solved. The afterglow of LED lamps A LED lamp is of course not an incandescent lamp and will therefore not really glow, but sometimes they will continue to burn very gently. Because LED lights only need a little bit of voltage, this can be enough to make them light. It is also possible that the voltage is not enough to make the lamp burn immediately. Then the voltage builds up, as it were, in the electronics, as well as in the lamp itself. If the voltage is high enough, it will discharge itself in the form of a flash, whereby the lamp is switched on for a very short time. The switch is off, so why does the LED lamp not go out and where does the voltage to light the lamp actually come from? This is due to a leakage current and it is virtually im...
