Electromagnetic Interference Risk Assessment for the use of LED Lights on Board of Ships

The very high frequency band is a critical band that is used for safety and distress communication on board ships. Use of some commercial off the shelf equipment have been found to cause interference in this band. This paper describes the use of a risk-based approach to evaluate EMC risk due to commercial-offthe –shelf light emitting diodes in the wider band surrounding then very high frequencies, and define measures for the integration without causing disturbance.

Measurements have been carried out on a sample of generic lights that are intended both for the indoor and outdoor use, to establish any likelihood of electromagnetic interference occurring. The results show some of the lights have higher emissions above the recommended limits, in which case risk-based EMC has been used to define mitigation measures for integration to achieve EMC.
