EN 61547 is a European standard covering the electromagnetic compatibility (EMC) of lighting equipment and installations. This means that lighting and related equipment must meet certain requirements to ensure they function correctly without causing or experiencing harmful interference with other electronic devices.
Key aspects of EN 61547
- The standard applies to general lighting equipment , including LED lighting, fluorescent lamps and other electric light sources.
- It establishes minimum requirements for immunity to electromagnetic disturbances such as:
- Radio frequency interference (RFI)
- Voltage spikes (transients)
- Electrostatic discharge (ESD)
- Variations in mains voltage frequency
- Devices covered by this standard must continue to function reliably in environments where electromagnetic disturbances may be present.
Applications
The standard applies to lighting products for domestic, commercial and industrial applications , including:
- Indoor and outdoor lighting
- Road lighting
- Public lighting
- Lighting systems in buildings and offices
Relation to other standards
- EN 55015 : Limits electromagnetic emissions from lighting products.
- EN 61000 series : Defines EMC test methods and limits for electromagnetic compatibility.
Why is EN 61547 important?
- Prevents lighting products from causing unwanted interference to other electronic devices.
- Ensures that lighting systems continue to function properly in environments with high electromagnetic activity.
- Is an essential standard for CE marking within the EU and is often required in product certification.
