Led light bulb or globe.

Car radio interference from led lights.

Hopefully this helps some. After some research we discovered that the cause of the radio interference was due to the pwm pulse width modulation circuit in the lights which was being picked up by the radio through the wiring. Also both of these products create rfi radio frequency interference. I was being driven insane by radio interference from my leds.

In the case of led lighting this could be. Oh it s definitely your hubby s fault kathy. Electromagnetic interference emi disturbance source this refers to the device emitting electromagnetic energy the source of the radio interference. But you already knew that.

The fm radio is from 240 volt 3 in 1 stereo. I use it as a worklight up on a wall at my shop just powered by a 12v car battery. When i turn it on the fm radio which is behind a wall from the light but speakers in the workshop side goes all static and crap. Lol the led that interferes with my fm radio is a single 12v 10watt smd.

I m guessing that the power source for the cheap poorly shielded led lights your husband bought probably is creating some radio frequency interference that s being picked up by the car s radio antenna. The german amateur radio club darc has issued a press release identifying domestic led light bulbs as a source of electrical interference. The increasing popularity of these light sources has led to a significant increase in reports of radio traffic disturbance interruption of radio services and even poor dab reception. Cyron motor abft100 h4 digital filter removes most all static radio emi interference and canbus errors caused by led headlights.

If the disturbance in terms of picture or sound is gone then the reason is most likely evident specifically due to rf radio frequency interference or emf electromagnetic frequency. This refers to the interaction between the source and the victim. We suggested installing a ferrite choke on the led leads and shipped a set of fair rite rf chokes to the customer. Coupling path conduction radiation.

In fact every electronic device ever made creates rfi but there are different types of this electrical interference.
