An LED lamp consumes several times less energy compared to an incandescent lamp. And for a little glow LEDs Just a few hundred microamps are enough. Therefore, very often you can notice the glow of an LED lamp after turning off. The problem is not critical, but sometimes unpleasant.
Let's look at all the possible causes of this defect and move on to eliminating it.
Reasons why an LED lamp glows after turning off
There are only two main reasons: This is current leakage through the wiring and the use of a switch with built-in lighting.
Let's start with the leakage current. Any wire insulation, even though it is a dielectric, still has a small resistance and is capable of conducting electricity. Light switches open only one contact and it can transmit voltage to the wall where it is routed through the insulation.
This happens in cases where the switch opens “zero”, and the phase remains connected to the lamp.
To check whether the switch is connected correctly, disassemble it and use an indicator screwdriver to check whether the phase is turned off.
The second reason why an LED lamp glows after being turned off is the use of a backlit switch.
The fact is that in each of them there is Light-emitting diode or a neon lamp included in the contact gap. And after switching off, enough current flows freely through it to ignite LEDs.
For these reasons, a fluorescent energy-saving lamp may blink.
How to eliminate the glow of a switched off LED paw with your own hands
To eliminate any of the listed defects you will need only one part: 0.1uF 400V AC capacitor.
It is enough to connect it parallel to the lamp, and the glow will disappear.
Therefore, at the place where the lamp is connected, simply connect the capacitor in parallel. Don't forget to turn off the power before starting work!
Next, install the lamp in place.
This capacitor Can also be installed in a power outlet.
Will an LED light consume more electricity?
Many people don't want to bet such a capacitor, because they are afraid of unnecessary energy consumption. This is a mistake, there will be no extra expense, rather the opposite. A capacitor is not a resistor; it does not create active power, but creates reactive power, which is not taken into account by electric meters. Capacitor in the network, on the contrary, it creates favorable consumption, since it dampens all vibrations and interference both for the lamp and from its operation.
