Temporal Light Artefacts

ZVEI information booklet about flicker and stroboscopic effect

All visual effects which are caused by light sources (and their changing intensity and spectral distribution over time) are known as temporal light artefacts. Key examples include flicker and the stroboscopic effect. The harmonization of drivers and LED modules plays an important role in LED light sources.

The ZVEI booklet "Temporal Light Artefacts (TLA) Flicker and stroboscopic effect" provides a comprehensive 14 page overview, including information, explanations of terms and definitions, as well as appropriate measurement methods. It also reports on the latest scientific work and standardization efforts. Also included are the positions of the European lighting industry association, LightingEurope.
