Why do my LED lights cause radio interference?

FAQ’s Radio Interference From Led Lights

Most often, the electrical ballast of the bulb is the one to blame, as it emits electrical signals. These are then received by radio, resulting in an unpleasant buzzing or humming noise.

How do you remove RFI from LED lights?

The most effective way to reduce RFI is to install an LDC into the lighting circuit. When an LDC is wired in series with the dimmer, it slows down the inrush of current during the rapid switching cycle of the dimmer. As the current inrush is slowed down, the effect of RFI on sensitive equipment is reduced.

Do LED lights emit radio frequency?

LED bulbs emit an electromagnetic field that works on the frequency between 400 and 600 THz. This is a much higher frequency than almost any household appliance.

Signal Emitted by LED Bulbs.

Household Item Frequency
LED Lights 400 THz to 600 THz

What causes radio interference?

Radio Frequency (RF) interference is caused by transmitters on the same or similar frequency to the one you’re receiving — for example, baby monitors, cordless phones, amateur or personal radio transmitters, oscillating amplifiers (like audio or radiating aerial amplifiers).

Can LED lights interfere with garage door opener?

In most cases, LED lighting can be used in an automatic garage door opener system and everything will work fine. … An LED bulb can interfere with the radio control signals so the door will not open reliably when activated by the radio control transmitter.

How do you get rid of static in a fluorescent light radio?

Try shortening the length of wire between your radio and speakers. Long speaker wire can pick up RFI and make it louder. Consider moving your radio to a different location. Moving your antenna to a new area may improve your reception enough to overcome the interference from fluorescent lights.
