Abstract

La présente invention a trait à un circuit d'attaque de diode électroluminescente et à une lampe fluorescente incluant celui-ci. Selon un mode de réalisation de la présente invention, un circuit d'attaque de diode électroluminescente comprend : une unité de réseau de diodes électroluminescentes dotée d'une pluralité de diodes électroluminescentes qui sont connectées en série ou en parallèle ; une unité de commande de courant constant qui est connectée en parallèle à l'unité de réseau de diodes électroluminescentes ; et un élément capacitif qui est connecté en parallèle à l'unité de réseau de diodes électroluminescentes. Par conséquent, il est possible d'obtenir une lampe fluorescente qui permet de maintenir une caractéristique de courant constant quels que soient les types de ballasts électroniques.
