Abstract

L'invention concerne des dispositifs d'éclairage d'intérieur/extérieur. La source de lumière à LED comprend un convertisseur abaisseur de tension (A), un pont de diodes redresseur (7), un filtre capacitif (C) et, au moins, une LED (11). Le convertisseur abaisseur de tension (A) est agencé comme un circuit de condensateurs connectés en série (5) et, à travers le pont de diodes redresseur (7), est connecté à, au moins, une LED (11). Le filtre capacitif (C) est connecté en parallèle entre le pont de diodes redresseur (7) et, au moins, une LED (11). Selon le modèle d'utilité, le pont de diodes redresseur est inséré dans une interruption d'un circuit de condensateurs connectés en série (5) du convertisseur abaisseur de tension. Une telle source de lumière à LED devient tolérante aux violentes fluctuations de la tension d'alimentation du secteur et permet d'améliorer la fiabilité de son fonctionnement dans les conditions de multiples allumages/extinctions répétitifs.
