Abstract

La présente invention concerne un appareil d'éclairage comprenant une source lumineuse de DEL présentant une durée de vie élevée et une excellente caractéristique de démarrage à faible température et présentant une structure compatible avec celle de lampes fluorescentes classiques. Les DEL sont alimentées en énergie électrique sans convertir la sortie du stabilisateur en courant continu, à la différence des techniques classiques. Par conséquent, l'appareil d'éclairage est dépourvu de pertes de puissance causées par la conversion par redressement et présente une efficacité d'utilisation de la puissance. A l'intérieur du corps de l'appareil compatible avec des lampes fluorescentes fixées aux appareils d'éclairage à lampe fluorescente existants se trouvent un condensateur de démarrage destiné à commander l'oscillation de courant alternatif du stabilisateur installé dans l'appareil d'éclairage à lampe fluorescente et des cartes de circuit imprimé sur lesquelles les DEL sont disposées. Le nombre de DEL est tel que les DEL reliées en série peuvent fonctionner dans chacune des polarités positive et négative de la sortie en CA du stabilisateur.
