Abstract

La présente invention concerne une douille à laquelle sont connectées des première et seconde lampes à LED à tubes droits. Les première et seconde lampes à LED à tube droit comprennent : un corps principal de forme oblongue ayant une première extrémité et une seconde extrémité, et retenant un groupement de diodes électroluminescentes ; une première bague disposée à la première extrémité du corps principal et présentant deux bornes d'alimentation électrique respectivement connectées aux deux extrémités du groupement de diodes électroluminescentes ; et une seconde bague disposée à la seconde extrémité du corps principal. La douille comporte des première et seconde parties de contact d'alimentation électrique destinées à assurer la conduction par l'intermédiaire d'un contact respectif vers les deux bornes d'alimentation électrique de la première lampe à LED à tube droit, et comprend une première partie de contact dans laquelle peut être montée de manière amovible la première bague de la première lampe à LED à tube droit, et une seconde partie de contact dans laquelle peut être montée de manière amovible la seconde bague de la seconde lampe à LED à tube droit. La direction dans laquelle la première partie de contact dépasse de la première lampe à LED à tube droit montée dans la première partie de contact, et la direction de dépassement de la seconde partie de contact de la seconde lampe à LED à tube droit installée dans la seconde partie de contact sont mutuellement parallèles.
