![]() ![]() The darker these bars, the worse the flickering is! DO NOT take a photo or video, just watch! If the lamp flickers, dark bars run over the picture / monitor. Hold the camera or mobile phone very close to the LED. Switch on LED illuminant and camera (start camera APP on the mobile phone). In our latitudes with a mains voltage of 50Hz and a normal camera or mobile phone (24fps) you can detect the most common 100Hz flicker. There is a very simple test that anyone can perform at home without any major aids, the so-called camera test. HOW DO I FIND OUT IF MY LED LIGHT IS FLICKERING? many G9 and R7s in glass housings and LED lamps with driverless AC direct technology. Nevertheless there is a lot of flickering even in the non-dimmable range, e.g. Many non-dimmable LED illuminants do not have the problem of flicker because they are based on another, simpler technology that produces a constant voltage. Therefore, we can assume that in most cheap products no or only insufficient ballast electronics are installed. ![]() However, this involves a material effort and therefore costs. Actually, LED lamps would need direct current to work ideally and to shine without any flickering.Ī ballast electronics in the LED illuminant (hidden in the base) converts the alternating current from the line into direct current, or modulates the frequency so that it is no longer perceptible.Ī high quality electronic circuit can reduce the flicker of dimmable LED lamps to nearly 0. Always to the positive and negative half-wave on and around the zero point off. And this always with double the frequency, the LED goes on and off 100 times a second. Exactly this alternating voltage is optically reproduced by the LED illuminant. To be exact 50 times a second, that is the frequency of 50Hz. In principle, it is quite simple to explain: Our current from the line is alternating current, which means that at very, very short intervals the voltage changes its polarity from PLUS to MINUS and vice versa. BUT WHERE DOES THE LED FLICKER COME FROM? ![]()
