What is Electromagnetic Interference

Electromagnetic Interference (EMI) refers to the disturbance caused by the flow of current through conductors and electronic components, resulting in the generation of a magnetic field that radiates from the source. This magnetic field can induce noise in nearby electronic devices and can also couple with internal electronic components, causing interference on the electrical supply and affecting other connected electronic devices.

EMI can have detrimental effects on the performance of electronic devices, including audio, video, and lighting systems. It can lead to audible noise in audio systems, visible noise in video systems, and degraded performance of lighting systems. In the lighting industry, large LED video displays are particularly susceptible to generating EMI due to the high amount of electromagnetic emissions they can produce.

To mitigate EMI, use lighting products that have been adequately designed and tested to reduce electromagnetic interference. This includes considering factors such as shielding of conductors, the material of the enclosure, circuit grounding, and other design considerations. LED video displays, in particular, should be designed to limit electromagnetic emissions and filter noise from the electrical supply. Third-party testing laboratories can provide documentation of the electromagnetic compatibility of these displays.
