Considerations on Electromagnetic Disturbances Produced by LEDs Light Sources

Abstract

In this paper, a series of theoretical and practical aspects are presented in the first instance that refer to the performances of a semi-anechoic chamber that exists within the profile laboratory at the National Institute for Research, Development and Testing in Electrical Engineering – ICMET Craiova. Measurements of electromagnetic disturbances were carried out at this location, which two LED lighting devices, namely a Flexi LED & Flash light tube and a LED projector, transmitted into the power supply network. Then the authors made a comparative analysis of the practical results obtained from these measurements of electromagnetic disturbances transmitted by conduction in one of the frequency domains (from 9 kHz to 30 MHz) provided by the reference standards.
