LED lighting is an energy efficient source of illumination that is becoming increasingly popular. However there have been many reports of interference to radio reception from these lights. Note this can affect AM, FM and DAB radio reception.
How do I stop my LED lights from interfering with radio?
How To Fix Radio Interference from LED Lights
- Use a quality LED bulb. …
- Change the transformer to one with better EMI suppression, such as our Verbatim LED transformer.
- Shorten the cable length, and if possible use a shielded cable.
- Add an EMI filter at the input / output of the transformer.

Why do LED lights make my radio static?
A conductive cable such as the input power for the HID or LED bulbs acts as an antenna – if the device produces radio frequency energy, this can be transmitted through the cable, which acts as an unintentional radiator. In this case the bead may be required to reduce RFI.
Do LED lights interfere with electronics?
All electrical devices, including LED lighting, emit electromagnetic radiation. However, the field generated by an LED light is not strong enough to cause interaction with WiFi or TV. On odd occasions the unshielded wires can produce a weak electromagnetic field, that might cause disruption.
Do LED lights give off radiation?
Unlike other energy-efficient types of lighting, the LED bulb does not emit polluting radiation and therefore does not pose a health hazard. … LED lighting also does not emit UV or infrared radiation, it does not contain mercury and is resistant to shocks and vibration even in a particularly cold environment.
Do LED lights cause RFI?
While the newer LED bulbs seem to be gaining in market popularity, both types of bulbs can contain electronics capable of causing RFI. … LED bulbs op- erate under Part 15 of the FCC rules. Typically, they are classified as an uninten- tional radiator, if their internal circuitry is operating at greater than 9 kHz.
Why do LED lights interfere with TV reception?
It turns out that using certain types of LED light bulbs can cause interference with some frequencies. The LED pulses on and off at a very high frequency (beyond that which our eyes can perceive), and this pulsing can create RF noise. If not shielded sufficiently, this RF noise can interfere with TV or radio signals.
Why are my LED lights buzzing?
LEDs lack a filament or firing arc so there are no “moving parts” to cause humming. Unfortunately, LEDs still suffer from electromagnetic (EM) hum caused by incorrect dimming or EM interference by other devices. … But, if your lights hum when dimmed or installed into sockets connected to a dimmer, it’s simple to fix.
How do you stop radio interference?
What to do about radio interference
- Check your equipment.
- Check your aerial system.
- Check for a weak signal.
- Check for multi-path interference.
- Check for radio transmitter interference.
- Check for co-channel interference.
- Check for electrical interference from power lines.
- Check for electric fence interference.
What causes static on FM radio?
Radio noise is a combination of natural electromagnetic atmospheric noise (“spherics”, static) created by electrical processes in the atmosphere like lightning, manmade radio frequency interference (RFI) from other electrical devices picked up by the receiver’s antenna, and thermal noise present in the receiver input …
What frequency do LED lights operate at?
Generic lighting tends to operate at frequencies of 50 – 90 Hz, which is designed to illuminate an environment and give the impression of a stable and constant light source – even though the LEDs are consistently switching on and off hundreds of times per minute.
What can interfere with TV signal?
This interference may be caused by equipment in your home, such as hair dryers, sewing machines, electric drills, doorbell transformers, light switches, smartphone chargers, power supplies, computing devices, washing machines, clothes dryers, fluorescent lights, LED lights, or garage door openers.
Do Smart Bulbs affect WiFi?
Smart LED light bulbs do not slow down the WiFi connection unless there are more than 20 bulbs all accessing a single router at the same time. Adding a hub decreases the number of devices on a network, freeing up router traffic, and increasing access.
Is LED light cancerous?
The ‘blue light’ emitted by LED light bulbs has been linked to breast and prostate cancer, according to a new study. Both breast and prostate cancers are hormone-related. …
Can you get cancer from LED lights?
LED Lights have not been found, in any studies, to cause cancer. The main cause of cancer in any light source seems to come from exposure to UV radiation and hazardous chemicals that may be found in incandescent and fluorescent light bulbs.
Are LED lights dangerous to eyes?
The “blue light” in LED lighting can cause damage to the eye’s retina and also disturb natural sleep rhythms, according to a new report. … “Exposure to an intense and powerful (LED) light is ‘photo-toxic’ and can lead to irreversible loss of retinal cells and diminished sharpness of vision,” it said.
