Abstract

La présente invention concerne un dispositif d'éclairage qui permet de raccorder un premier élément conducteur et un second élément conducteur à l'intérieur d'un logement. Le dispositif d'éclairage est conçu de telle sorte qu'un premier élément conducteur (33b) sur un côté substrat (33) et une borne femelle (52) sur un côté dispositif de commande embarqué (CU) sont raccordés électriquement l'un à l'autre à l'intérieur d'un logement (32). Du fait de cette configuration, dans un cas où un élément élastique tubulaire (70) est fixé au logement (32), même si un obstacle entre en contact avec le logement (32) et l'élément élastique (70) devient sensiblement courbé en conséquence, la déconnexion de la connexion électrique entre le premier élément conducteur (33b) et la borne femelle (52) est empêchée.
