Abstract

With a view to characterize the electromagnetic interferences (EMI) due to a model of Light Emitting Diode (LED) lamp used in street lighting, measurements of radiated emissions were conducted both in situ and in an Electromagnetic Compatibility (EMC) laboratory. The in situ measurements were carried out using an Anritsu MS2724B spectrum analyzer in conjunction with a directional antenna, in the frequency range from 20 MHz to 200 MHz, at 10 m distance from a number of LED lamps. The EMC laboratory measurements were conducted in compliance with the European Standard EN 55015, “Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment”. The paper presents measurement results obtained in the two situations, which indicate that the emissions from the considered LED lamps exceed the imposed EMC limits and so EMI problems appeared by using these products.
