Claims (1)

  1. Dispositif d'alimentation en puissance de lampes fluorescentes à décharge, du type comprenant un unique ballast (1) convenant à un unique tube individuel qui alimente une rangée de multiples lampes fluorescentes, caractérisé par le fait que les lampes (2, 3) sont de type identique et sont connectées en parallèle aux bornes (7, 8 ; 9, 10) du ballast (1), illuminant une seule desdites lampes, au sein du jeu des lampes fluorescentes, et continuant d'illuminer automatiquement d'une lampe à l'autre lorsque la lampe éclairée cesse de fonctionner, le ballast (1) renfermant en succession, avec intégration monolithique dans un unique bloc (17) de résine isolante, un bloc (11) comportant des filtres et des antiparasites ; un bloc (12) comportant un redresseur et des protections ; un bloc (13) à correcteur de facteur de puissance et augmentateur de différence de potentiel ; un bloc (14) à commande de commutation et de haute fréquence ; un bloc (15) à commande de lampe et d'actionnement de puissance ; un bloc (16) à détecteurs d'absence, de potentiel et de courant, demeurant dans le bloc de connexions à résine isolante gagnant les conducteurs de puissance et les conducteurs qui alimentent les lampes en parallèle, qui sortent en traversant une paroi du bloc de résine sans exposer une quelconque connexion.
