Experimental evaluation and classification of LED lamps for light flicker sensitivity

Abstract

The paper reports on the experimental evaluation and classification of LED lamps for light flicker sensitivity. After the description of the experimental setup designed for tests, a classification based on the driving circuits is proposed. For each class, the circuit description and the Gain Factor (GF) curves versus interharmonic frequencies are reported. Finally, a comparison of the different GF curves is presented to show the Light Flicker sensitivity of the tested LED lamps.
