Abstract

L'invention porte sur un élément lumineux à courant alternatif qui comprend des première et seconde bornes de connexion d'alimentation connectées à une alimentation externe, et une pluralité de blocs de cellules lumineuses connectés en parallèle entre les première et seconde bornes de connexion d'alimentation, et configurés pour être mis sous tension à différentes tensions. Dans l'élément lumineux à courant alternatif, une pluralité de réseaux de cellules lumineuses connectés en série sont inclus dans la pluralité de blocs de cellules lumineuses, respectivement. La même tension est appliquée à la pluralité de blocs de cellules lumineuses. La pluralité de réseaux de cellules lumineuses sont formés sur une tranche unique.
