Abstract

L'invention concerne un système composé d'une douille de lampe (11) et d'un culot de lampe (12) notamment pour ces moyens d'éclairage pour lesquels une dissipation de la chaleur est souhaitée. Pour optimiser le transfert de chaleur entre culot de lampe et douille de lampe et leurs surfaces thermoconductrices, il est prévu un accouplement magnétique (38) qui permet de créer une force de serrage définie entre les surfaces thermoconductrices (22, 43). Simultanément, il est possible de disposer l'un sur l'autre de manière fiable le culot de lampe et la douille de lampe grâce à l'accouplement magnétique.
