When LEDs are used for film applications (e.g. The most common cause of flickering LED lights is a poorly matched LED power supply, otherwise known as a LED driver. Although the lighting industry generally knows its power supplies (aka ‘drivers’) simply as ‘LED transformers’, they’re actually more than that. Solid state switches used for switching on and off the LED lights usually leak a very small quantity of electric current. You could start with a 1k ohm resistor. Check for loose wiring and other faulty connections. Our products include AC/DC switching power supplies, LED Drivers, DC/DC converters, DC/AC inverters and battery chargers. Check the alternator/generator with a voltmeter. Always drive LED products using an LED power supply that’s designed for the job. So if connected directly to an AC mains-electricity supply, an LED will switch on/off 50 times each second – enough to be visible to the human eye. 4 Attach An EMI Filter EMI (Electromagnetic Interference) filter is known to function by suppressing or lessening the conducted interference in a power line. These old incandescents typically wasted around 90 percent of input energy through heat! Even though you don’t always see it, all mains-powered light sources flicker – whether incandescent, halogen, fluorescent or LED. The capacitor stores energy to keep the lights on (for a short interval) until power comes back. So it causes flickering in the LED lights even when they are switched off. If you use the wrong type of LED driver for your light fitting then the LED light will flicker when there are fluctuations in the incoming AC power at the wall socket, as there often is. Unplug the power cord connecting the LED light to the AC outlet. It does this by adjusting the output current accordingly. All mains-powered light sources flicker, all the time. But if a simple LED power supply isn’t enough for your project, then an excellent alternative for you would be a constant-current power supply.
