Lighting Flicker of LED Lighting Systems

Flicker is the modulation of a lamp’s light output caused by uctuations of the mains voltage supply. Recent research has shown that uctuations of short wavelength emissions are perceived to a higher extent and light icker may have a huge in uence on the well-being of end users. Prof. Georges Zissis, Head of Light & Matter Research Group at the LAPLACE Université de Toulouse presents and discusses the in uence of driver topologies, research results, metrics and standards.
