Abstract

L'invention porte sur un circuit d'attaque de diode électroluminescente comprenant : une unité de limitation de courant constant qui limite de façon régulière le courant circulant dans un circuit de diode électroluminescente (DEL) indépendamment d'une tension d'entrée appliquée au circuit DEL qui comprend au moins une DEL à laquelle une puissance d'entrée en courant alternatif est appliquée par l'intermédiaire d'un circuit en pont ; et une unité de prévention d'augmentation de puissance de sortie qui empêche la puissance de sortie du circuit DEL d'augmenter lorsque la tension d'entrée appliquée au circuit DEL est augmentée.
