Abstract
L'invention concerne une guirlande constituée d'ampoules incandescentes (12-21) connectées en série dans laquelle sensiblement tous les filaments se trouvant dans l'ensemble sont dotés individuellement d'un élément de dérivation (31), lequel est inopérant pendant le fonctionnement normal de l'ensemble et fonctionne pour assurer la dérivation uniquement lorsque l'augmentation de la tension dans l'élément de dérivation dépasse une valeur prédéterminée.
