Low Cost Device For Light Flicker Measurement

Abstract- A new instrument for the evaluation of disturbances caused by variations in lamp voltage (light flicker) is proposed, based on light intensity measurements. Unlike current standard (IEC EN 61000-4-15), which determines flicker severity by filtering powering voltage measurements with a standard lamp model (230V/60W), the presented methodology includes the lamp itself in the measurement process, thus realizing an objective measurement of flicker. A testing station for the metrological characterization of the device has been implemented and measurements have been compared to a standard IEC flickermeter (Norma D6000). Thanks to its portability, the instrument can be used to measure light flicker over a wide range of environments spanning from home/office to rial locations. I
