Ce câblage de chaînes de DEL est conçu de sorte que, lorsque la tension d'alimentation augmente, les chaînes de DEL individuelles sont câblées par ordre croissant de leur nombre ordinal N et, lorsque la tension d'alimentation baisse, les chaînes de DEL individuelles sont déconnectées par ordre décroissant de leur nombre ordinal. Un circuit résistant commandé est associé à la borne de tension d'alimentation globale, ledit circuit résistant étant conçu de sorte que, jusqu'à un premier courant limite et/ou à partir d'un deuxième courant limite, une résistance ohmique est câblée de sorte que le courant d'entrée du luminaire soit sinusoïdal.
