Frequently, those who only installed new LED techniques in their home, pay attention to that savings lamps are starting to flicker when the light is turned off. It is obvious that such behavior is not normal. As you can and should be taken in such a situation to solve the problem once and for all. Is the shimmering lamp really faulty?
The thing is good.
When you see a shimmering LED lamp (especially after turning off the light), the first idea that inevitably comes to mind lies in the fact that the newly installed, new lighting does not work. So you need to run to acquire and immediately install a new LED light bulb. In fact, everything is not so simple and definitely. There are three main reasons for such "bad behavior."
Important: The easiest way to overcome flicker is to put an ordinary incandescent lamp.
The case can be in the wiring.
The first reason for the flicker may be that the bought LED light bulb is really poor and does not work as it should be. In this situation, the product is really correct to replace with the new one. The second reason for flicker is the poor condition of the electrical wiring in the room. In this case, leaks arise, so-called parasitic currents. The third reason is the presence in the switch that is responsible for switching the lamp switching, the built-in indicator.
That's the problem.
Very often flickering lamps in the third reason. The fact is that in timely illuminated switches, a LED with a current-limiting resistor is used. It turns on the input and output terminal of the commuting instrument. Thus, on the lighting device, the supply voltage of 220 volts will arrive, being limited to additional resistance. The element capacitor is charged when small currents in the backlight circuit and how the total appears, then the flicker appears. This problem is solved by replacing the switch or dismantling the highlighting element.
You need to choose the right lamp.
Important: In really high-quality LED lamps, the capacitance of the capacitor is such that the frequency of flicker increases to the inaccessible human factor of the frequency.
Now, with regard to the influence of wiring. Most often, flickering occurs due to it if the insulation was broken somewhere. Damp, accumulated dust, mud can enhance the current leakage from the chain. As a result, the LED lamps begin to flicker with the frequency of the discharge of the capacitor installed in them. In this situation, it is possible to solve the problem only with the replacement of old wiring to a new, better.
