Introduction to EMC Testing for Luminaires and Lighting Products
Category:
EU CE-EMC
Lighting fixtures / Electromagnetic Compatibility (EMC) of Lighting Products, including electromagnetic interference (EMI) and electromagnetic immunity (EMS).
Most electrical lighting products today contain electronic control devices, such as transformers, power supplies, electronic ballasts, or drivers connected to low-voltage power sources. These devices generate electromagnetic fields in circuits, which may cause electromagnetic interference (EMI) to other nearby equipment. For example, common EMC issues in LED lighting include interference with other electronic devices in the home, especially audio and video equipment, such as televisions, radios, and communication devices.
On the other hand, lighting products may also be exposed to electromagnetic interference from various sources during use. If the product does not have sufficient immunity, external interference may cause unstable operation or even damage. This electromagnetic immunity is referred to as EMS.
The European Union has implemented EMC regulations for these lighting products, requiring them to comply with applicable EMC standards and bear the CE marking before being sold in the European market.
Note: CE Countries where the mark is valid - European Economic Area (EEA), including the 27 European Union member states, Germany, Liechtenstein, Iceland, and Norway.
EMC Luminaires Subject to Certification / Lighting products include:
Light tubes, globe lamps, tunnel lights, industrial and mining lamps, streetlights, fluorescent lamps, desk lamps, floor lamps, ceiling-mounted spotlights, wall lamps, lamp shades, recessed ceiling spotlights, cabinet lighting, light strips, flashlights, etc.

EMC Reasons for Test Failure
Common EMC tests that may fail include radiated emissions (RE), radiated immunity (RS), and electrostatic discharge immunity (ESD). The common causes of failure include:
1.PCB Design: Poor Board Layout and Layer Stackup
2.Cable Shield Termination and Pigtails: The cable shield is not properly terminated to the enclosure, or non-shielded products lack common-mode filtering, with issues further worsened by the use of shielded pigtails.
3.Gaps in the Return Path: High-frequency clocks or signals cross gaps in the return path.
4.Power Distribution Design: Poor power distribution network (PDN) design.
5.Shielding Design: The holes or slots in the shielding enclosure are too long.
