Abstract

L'invention concerne une guirlande lumineuse comprenant une pluralité de lampes et une pluralité de segments de fil conducteur connectant les lampes ou une lampe à un connecteur d'alimentation électrique. Chaque lampe comprend une ampoule électrique (1) et un boîtier d'éclairage (2). Deux broches de lumière (11) font saillie sous l'ampoule électrique. Le boîtier d'éclairage comprend une partie de réception configurée pour recevoir l'ampoule électrique. Une partie inférieure de la partie de réception comprend une ouverture dans laquelle l'un des segments de fil conducteur est inséré. Une isolation en matière plastique de l'un des segments de fil conducteur comprend un trou (45) dans la broche d'éclairage qui est insérée. Les broches d'éclairage sont insérées dans les trous pour réaliser des connexions électriques entre les broches d'éclairage et les segments de fil conducteur. La guirlande lumineuse présente une structure simple et permet de connecter facilement les lampes et les segments de fil conducteur. L'invention concerne également un procédé de protection de surintensité.
