if you are looking for the solution to 12v led lights flickering problem, then read this article carefully. Here I am talking about flickering problem of 12v led lights and how to handle it with simple words.

12v led lights flickering problem

Almost all the manufacturers say that the LEDs used in 12v LED lights flicker at this voltage. Yes, the lights flicker, but the flickering is not noticeable to human eyes. Well, some research has shown that LED lights flicker in the range of 0.4 Hz to 120 Hz. The flicker rate varies with each manufacturer and the factors like the type of LED used, the number of LEDs in the array, the amount of current flowing through them, power losses encountered in the wiring, and the nature of the load. The flicker rate is inversely proportional to the brightness of LEDs. The brighter the LED, the lesser the flicker rate.

What is the reason LED lights flicker?

Light-emitting diodes (LED) are semiconductor devices that emit light when current passes through them. The current goes through a silicon wafer with a controlled number of impurities in it. The impurities, referred to as “dopants”, are added to the silicon to change its conductive properties. The amount of dopants determines what color the LED will be, as well as its forward voltage, current rating, and wavelength of light.

The voltage for each LED determines its brightness. If the forward voltage is below the rated voltage of the LED, it may flicker. The source of the flickering is a result of the forward voltage of the LED exceeding the voltage rating of the LED. Therefore, if you are experiencing flickering with the LED, try to use a more powerful current.

There are several possible causes of LED light flickering. The first one is faulty manufacturing. Even though the LED bulbs have passed strict quality control, there is still possible that it was manufactured incorrectly. As a matter of fact, it is quite normal to see some flickering in new LED bulbs. If you have recently bought an LED bulb and it flickers, try to keep using it for a few days or weeks. You can also try different channels to see if you can find a good one. If the flickering is still present after a week or so, you may want to contact the seller and get a replacement.

How do I fix 12v led lights flickering?

LEDs flicker when the voltage is not steady. This can happen due to bad wiring or can be caused by light dimmers or heavy loads. The solution is to use a led driver to maintain the voltage as steady as possible, so the LEDs won’t flicker.

The flickering is caused due to the AC current, which goes through the LEDs. This causes the LED to glow dimly and brightly at odd intervals. The LEDs are not visible when they are dim, but when they are brightly glowing, they are easily visible. However, the flickering is still not very visible to human eyes, but some sensitive people can feel it. The flicker is not harmful. However, when using the LEDs in the car, doing so can be really annoying.

You may be having a voltage problem. You can check the voltage with a multimeter. If it’s too low you may have a bad battery, it may be draining the power supply. If the voltage is okay, then you should have an overload. A switch is an overcurrent protection device. If too much current passes thru the switch, it will fail and open up. If this is the problem, then you’ll have to replace the switch.

On a 24 volt system, the standard way to control the LEDs is to have a simple relay on the transformer. This relay has three wires, one for the load, one for ground, and one for 12 volts. 12 volts are connected directly to the load, which is the LED. The ground is connected to the case of the LED. The relay needs three wires, one for the 24-volt input from the transformer, one for the load power (either the GFCI outlet or the 12V to the LED), and one for the ground. The load is controlled by connecting the path between the 12 volts and load to the output of the relay.

Can flickering lights cause a fire?

Yes, flickering lights can cause a fire.  fires are started by things like this, either because the light bulb burns out or the light fixture overheats. Some things to remember:
  • Don’t overload your electrical circuits.
  • Replace your light bulbs when they burn out.
  • Use bulbs that are in good working order.
  • Don’t put light bulbs in lamps where the lampshades clip in place.
  • Use bulbs with a medium wattage rating.
  • Don’t use bulbs that are more than 10 years old.
  • Don’t have your wiring or light fixtures checked out by someone who does not have a license to do so.

Why do dimmable LED lights flicker?

The dimming demand for LED lights adds a huge challenge to engineers who are working on LED lighting. The first reason for LED lighting to flicker is the LED itself. LED lights flicker because current LED lighting products are not AC-coupled. Although LED lights flicker, it’s not visible or bothering because the brightness of LED lights changes only slightly.

An LED flickers when the amount of current flowing into the LED is changed. Most AC bulbs are driven by a large AC transformer. However, there are some LEDs, especially the high-brightness types, that possess a lower-voltage drive than the standard AC supply. So, although dimmable LEDs may flicker, it does not have any negative effect on human health.
