Abstract

L'invention concerne un procédé destiné à contrôler si au moins deux lampes à décharge gazeuse (L1, L2) destinées à fonctionner avec un ballast électronique (V) sont du même type. A cet effet, la tension et le courant d'un filament de chauffage respectif (W1b, W2b) de chaque lampe à décharge gazeuse (L1, L2) sont mesurés à un premier instant et les résistances de filament (R1cold, R2cold) sont calculées à partir de ces mesures. La résistance différentielle absolue (IRdiff l) est ensuite calculée à partir des résistances de filament (R1cold, R2cold). La résistance différentielle absolue est comparée à une valeur de référence supérieure et à une valeur de référence inférieure. La comparaison permet de déterminer si les deux lampes à décharge gazeuse (L1, L2) sont du même type.
