Case Study: Solving EMI Conducted Disturbance in LED Luminaires

2026-09-01

1. Project Background

Product Type: High-Performance LED Luminaire
Test Standard: EN55015
Test Category: Conducted Disturbance (EMI)
Core Component: VIIP White Amorphous Ferrite Core

2. The Technical Challenge

During the initial electromagnetic compatibility (EMC) pre-test, the luminaire showed high levels of conducted noise. An initial attempt using a 16FJ amorphous core with 2 turns yielded a 7dB margin, but it was borderline for certain frequency points, risking inconsistency in mass production.

3. The VIIP Solution

Our engineers recommended upgrading to the VIIP 20FJ Amorphous Ferrite Core (the white toroidal core shown in the visuals). By increasing the configuration to 4 turns, we effectively increased the high-frequency impedance, creating a more robust barrier against electromagnetic interference.

4. Results and Validation

Outcome: The luminaire successfully passed the EN55015 standard.
Performance: A stable 7dB margin was maintained across the spectrum without any problematic "reading points."
Efficiency: The amorphous material allowed for superior suppression with a compact size, fitting perfectly within the limited space of the LED driver compartment.

5. Why Choose VIIP Amorphous Cores?

Superior Permeability: Higher impedance than traditional ferrite, reducing the number of turns needed.
Thermal Stability: Maintains consistent EMI suppression even under high-temperature operating conditions.
Proven Compliance: Trusted by manufacturers to meet EN55015, CISPR 15, and other international lighting standards.
