Title
(EN) LED BULB AND METHOD OF MANUFACTURE
(FR) AMPOULE À DEL ET PROCÉDÉ DE FABRICATION
Abstract
(EN) An LED bulb includes a center ring, a burner and an elastic component. The center ring includes a central opening, a first flat rim extending along a first part of an outer edge of the central opening, and a first notch cut-out beyond the central opening at an end of the first flat rim. The burner is disposed at least in part in the central opening and includes a first pin that has a first flat side face. The elastic component is configured to press the first flat rim of the center ring against the first flat side face of the first pin of the burner.
(FR) L’invention concerne une ampoule à DEL qui inclut un anneau central, un brûleur et un composant élastique. L’anneau central inclut une ouverture centrale, un premier bord plat s’étendant le long d’une première partie d’une arête extérieure de l’ouverture centrale, et une première encoche découpée au-delà de l’ouverture centrale à une extrémité du premier bord plat. Le brûleur est disposé au moins en partie dans l’ouverture centrale et inclut une première broche qui a une première face latérale plate. Le composant élastique est conçu pour presser le premier bord plat de l’anneau central contre la première face latérale plate de la première broche du brûleur.
