Why Does my TV Remote Control my LED Lights?

The first and most common question people ask when they purchase their LED lights and then discover that their TV remote control works with them is, why?

It seems like an odd match, LEDs are light-emitting diodes, while TVs are picture devices that need to be illuminated.

What similarities do they have that will make the TV remote to be able to control the LED light? Keep reading as we talk about the nitty-gritty of it.

It happens when the infrared signal sent from your TV remote and supposed to be received by the TV’s sensor is instead received by the LED light’s sensor.

This mostly happens when there’s close proximity between the two infrared devices (that’s the television and LED lights) or if there are reflective surfaces that bounce back and forth between them.

The infrared emitter on your television remote control sends out a continuous beam of energy.

This helps you use your remote to control various devices, like your television and Blu-ray player. But these signals also can be picked up by other devices, such as some LED lights.

That’s why pressing a button on your remote can change an LED light from green to blue to purple, depending on what device you’re trying to control. Your LED light isn’t broken; it’s just receiving signals not permitted.

If you have other devices that use infrared, like sound systems or air conditioners, make sure it’s far enough away from your television, so they don’t pick up its signals. Also, avoid placing reflective surfaces between your remotes and their respective devices, if possible.

Why does my TV control change my LED lights?

This happens when the infrared sensor in the LED light also receives infrared signals from the remote control.

Once the remote signals come in contact with the television, the same signals can also find their way to the LED and react with its sensor.

The LED then assumes that you are attempting to change its settings and reacts accordingly.

While it is possible to turn off your TV remote’s ability to send out infrared signals which finally get to the LED light, most people do not bother as it is a relatively harmless feature.

But if you are bothered by your remote controlling your lights, there is an easy fix: simply tape over or remove the sensor on your LED light so that it cannot receive any of these unwanted signals.

You can still use your remote control as normal without interference from other taped-sensor electronics in your home.

Can you use a TV remote for LED lights?

This won’t be possible if the TV remote is being used to adjust an LED light’s settings.

What usually causes the TV remote to control some features of the LED light is that the signals being sent to the television are sometimes picked up by the LED light sensor and used to make changes.

You’ll need a universal remote with a learning feature to properly replace your TV remote with a light remote.

The remote you purchase will allow you to program its buttons to be used for both purposes without needing separate remotes for each device. With a few simple steps, you can use one device to operate both devices as needed.

However, some specific types of LED light may not be able to receive signals from the same remote programmed for your television.

In these cases, it would be necessary to have two different remotes, one for your television and another for your LED lights.

This isn’t necessarily bad, though, as most people use their television remote far more often than their light remote. Therefore, having two remotes can save time and energy overall.

How do I stop my TV remote from controlling my LED lights? How do I stop my TV remote interference?

Your television remote may be able to control your entire home, but this comes with a risk if you’re not careful.

Many homes today are equipped with LED lighting, which can be controlled by the same remote your TV operates on. While this can be convenient, it can also be worrying.

Several ways exist for you to use to stop the interference between your TV remote and LED light.

We will review a few of these many methods. You’ll then be able to go with the solution that most efficiently takes care of your interference.

Changing the receiver of either device, that’s the television or LED light, is like buying a new whole device.

So before you fall on replacing either the LED light or television, let’s look at these suggestions.

Increase the distance between both receivers.

The best way to avoid interference is to keep your television IR sensor and LED light IR sensor as far apart as possible.

You can do so by placing them on opposite sides of a room or by hanging your TV on one wall and mounting your LED lighting fixtures on another wall.

If you’re using a remote extender, try increasing its distance from both devices or moving it closer to one device while moving it farther away.

Install a shield between both receivers or around the LED light receiver.

Shielding is a metal barrier that prevents electromagnetic waves from entering or exiting a certain area.

If you place your LED light receiver in a shielded box, it will stop receiving interference from the TV remote. You can buy shielded boxes at electronics stores and online.

Alternatively, you can make your own using tin foil and a cardboard box. Just wrap your LED light receiver in several layers of tin foil and put it inside a sturdy cardboard box.

Ensure to leave an opening for power cords to enter and exit the enclosure. (Don’t worry; most receivers don’t need to be connected to anything except power).

When you’re done, test out your new setup by pointing the TV remote in the direction of the LED light IR sensor to see if it can pick the signals from the TV remote to cause any interference.

Using switches instead

Another way to keep your TV remote from interfering with the LED light is simply using a manual switch.

In this way, you can still operate the television without worrying about the TV remote and its potential interference.

If you need to turn on or off the television, toggle to another station, or make the television louder, you just walk to the TV and press the buttons that correspond to your desired functions.

You could use a strip of electrical tape to block the sensor of your LED light, preventing the signals from the TV remote from reaching it. That way, even if you point the TV remote to it, it wouldn’t affect the LED light.

Conclusion

There are several reasons why your remote control may be affecting your LED lighting.

But the basic of it all is because the TV remote and LED light remote all use infrared in sending their signals when the infrared signals sent by the TV remote to be received by the television’s IR sensor are also picked up by the IR sensor of the LED light. It takes action, assuming the signal or message was meant for it.
