Considerations for measuring the ElectroMagnetic Interference of LEDs projectors with the supply electrical network

Abstract

In this paper, the authors present the results of the disturbance measurements transmitted in the power supply network by a YIYI Type LEDs projector. This complex program of disturbance measurements, consisted of measurements of disturbances transmitted by conduction in the frequency range 9 kHz ÷ 30 MHz and radiated disturbances in the frequency range: 9 kHz ÷ 30 MHz, respectively. The penultimate section of the paper presents the interpretation of the measurement results, the levels of disturbances transmitted by the tested LEDs projector and an analysis of the disturbing effects on the power supply network produced by this type of LEDs projectors. In this sense, the test report performed in an existing semi-anechoic chamber (SAC) within the Low and High Voltage Testing.
