Abstract

La présente invention concerne un dispositif d'excitation pour un dispositif d'émission de lumière, lequel dispositif d'excitation comprend : une unité de filtre qui reçoit une tension alternative, et qui délivre la tension par élimination du bruit ; une unité de redressement qui redresse la sortie de l'unité de filtre, et qui délivre une tension d'excitation ; une unité de compensation qui élimine le bruit d'un courant d'entrée correspondant à la tension alternative, et qui transfère la tension d'excitation à un dispositif d'émission de lumière par compensation de la taille de la tension d'excitation; et une unité de courant constant pour maintenir de manière constante un courant circulant dans le dispositif d'émission de lumière, permettant ainsi d'améliorer un facteur d'alimentation et des caractéristiques de taux d'harmoniques, d'exciter le dispositif d'émission de lumière à l'aide d'un courant constant, et, en même temps, de réduire le papillotement.
