Abstract

L'invention concerne une douille à ballast pour lampe fluorescente compacte. Ladite douille comprend un boîtier doté, d'une part, d'un boîtier supérieur qui comprend un espace de logement servant à recevoir une lampe et une borne de connexion connectée à la lampe au niveau d'un côté de l'espace de logement et, d'autre part, d'un boîtier inférieur pourvu d'un trou traversant au niveau d'un centre inférieur du boîtier supérieur, un dispositif de commande monté à l'intérieur du boîtier servant à réguler l'éclairage de la lampe, des broches servant à connecter la carte de circuit imprimé et le terminal de connexion, et une carte de circuit imprimé, sur laquelle sont fixés divers composants de circuits. Ladite douille semble similaire à une douille de lampe incandescente sur le plan de sa forme externe, mais la lampe fluorescente compacte qui n'a pas de ballast, est utilisée dans la douille de ballast. De ce fait, la douille à ballast permet d'éviter le gaspillage des ressources et la pollution de l'environnement, puisqu'elle économise l'électricité et améliore la productivité de la lampe par le biais de la fabrication d'un ballast qui n'adhère pas à la lampe.
