Title
(DE) EMV-VERBESSERUNG DURCH HF-ABSORPTION IN LEUCHTEN UND EVGS
(EN) EMC IMPROVEMENT BY MEANS OF RF ABSORPTION IN LUMINAIRES AND ELECTRONIC BALLASTS
(FR) amélioration EMV par absorption HF dans Des lampes et Des EVG
Abstract
(DE)
Die Erfindung betrifft die Verbesserung der EMV eines EVG oder einer Leuchte mit integriertem EVG durch Einfügen eines hochfrequenzabsorbierenden Dämpfungselementes (F), insbesondere einer Ferritperle.
(EN)
The invention relates to the improvement of the EMC of an electronic ballast or a luminaire with an integrated electronic ballast by means of introducing a radiofrequency-absorbing damping element (F), in particular a ferrite bead.
(FR)
L'invention concerne l'amélioration des EMV d'un EVG ou d'une lampe à EVG intégré, par insertion d'un élément d'atténuation (F), en particulier d'une perle de ferrite, qui absorbe les hautes fréquences.
