EN 61547 specifies the requirements for the immunity of lighting equipment to electromagnetic disturbances. It applies to devices that produce light for general illumination and includes both indoor and outdoor lighting equipment. The standard ensures that such equipment does not emit electromagnetic disturbances that could interfere with other devices and is resistant to disturbances from external sources, such as radio-frequency interference. This standard is crucial for maintaining the reliable operation of lighting equipment in various environments and ensuring compatibility with other electronic devices.
