Have you ever been in that situation when you are watching your favorite sport on TV, and suddenly the screen looks like sea-waves?
At first, you may think there is something wrong with your TV or the frequency of your DTH. But as soon as you realize it’s nothing like you thought, you may get surprised to know what really plays the trick!
There is something known as radio interference that comes from your LED light, and it can hamper the regular operation of your TV, radio, and other electronic devices.
So how to fix radio interference from LED lights? Follow our lead to find it out!
What Exactly Is a Radio Interference?
It basically is a type of disturbance related to signal of electrical devices, that results in a momentary loss of frequency reception and low-quality image.
This also causes the electronic devices to create some type of static noise, which interferes and causes a disturbance with the functions of the device.
As the most common victims of such interference are radios, TVs, laptops, or desktops, most owners are very keen to know what’s really going on and how to get rid of it.
Well, to do that, you need to make sure that the issues are actually caused by the LED lights. You can check it out by turning the lights off or removing them away while you test the electronic devices afterward.
If your TV or radio is working fine, then you can be sure that the issue was being created by the LED light. The main reason behind it is the interference of your device.
So what is going on actually? Why does this happen? Well, it’s basically an interaction between two electronic devices.
To be specific, the radio frequency interference source, which is the LED light, emits electromagnetic energy, and that’s the light we see. Now, the light is radiated and carried by a cable or the ceiling of your room.
Eventually, the energy is received by the affected devices, such as TV, radio, etc.
How to Fix Radio Interference?
Seriously, nobody wants to see TV like a sea-wave or listen to the robotic voice on the radio. Everybody needs a solution when it comes to interference. So how to solve this problem? You can’t just let the LED lighting system of your house go all of a sudden because of this. So we have gathered some solutions to this.
Consider Changing the Transformer
There are many poor-quality transformers out there that do not live up to the standard.
These low-quality transformers can ease the way to radio interference. Make sure you are choosing a better quality transformer for your house even if the device comes with a higher price.
Before getting one for you, definitely check the specs and all the information that is presented on the device packaging. If the machine seems to be able to counter radio interference, you should go for it.
Moreover, choosing transformers that come with better EMI suppression is the best option you have.
Scrutiny of the Cable Length Is Necessary
As we have discussed earlier, cables can conduct and receive many useless and unwanted signals from nearby devices. So you have to keep the length of the cable as short as possible.
Otherwise, the cable can attract random frequency, and it will cause the hamper in the frequency.
There are cables that are shielded. You can consider buying those for added protection.
Try Altering the LED Bulb
One of the best options you have is that you should get the bulb that confirms you of better quality. All the bulbs have necessary standards to follow, and you may find some of these bulbs are complying to the standard at maximum level.
These bulbs may cost you more, but you can get rid of those annoying radio interferences once and for all. Remember, if you are investing a bit more in your lighting system, you will be saved from spending more on repairing in the future.
Attaching an EMI Filter Is a Good Idea
EMI filter works by overpowering or reducing the interference in a line where power is traveled. By this system, the signal quality gets better, and the RF interference is mitigated. You can add this to either the input or output area of the transformer.
What Types of LED Bulbs Are to Blame?
There is no straight forward answer to this. But basically, any low-quality and low-priced LED bulbs can cause interference. If you don’t want this, you should always consider buying bulbs with better specifications, quality, and obviously, price.
In addition, the bulbs that come with seals that reads ‘tested’ or ‘well-trusted’ can actually be trusted and bought. Some of the famous brands even advertise their bulbs as their bulbs don’t cause interference.
When Does the LED Light Cause Interference?
Usually, if the light is not emitting light for 24 hours a day, you will not be facing the interference problem every day. It only occurs when you turn it on.
So turning it off immediately after the interference issue can be an immediate solution to this. But to solve in the long run, you may consider changing the light for a better one, as we have discussed before.
Now that you know how to fix radio interference from LED lights, it’s easier for you to go for the solution in your home. So the next time you hear a spooky sound on your radio, or pixelated videos on your TV, don’t freak out.
Try to follow the different ways we have discussed here as a solution. If there is a problem with your device, consult a technician.
But if you can identify the problem lies in the LED lighting system of your house, you can wear your expert cape right there. Try to solve the problem yourself. Follow the steps we have discussed. You can surely make a difference!
