Abstract

La présente invention concerne un dispositif de refroidissement pour réflecteurs. Ce dispositif de refroidissement se caractérise en ce qu'au réflecteur 2, on a associé un corps de refroidissement métallique 5 disposé immédiatement à côté de l'enveloppe du socle dudit réflecteur 2 présentant un faible écartement par rapport à ce dernier. Le corps de refroidissement 5 comprend des nervures de refroidissement 5a pour l'évacuation de la chaleur. L'écartement 11 entre les surfaces voisines du réflecteur 2 et du corps de refroidissement 5 est avantageusement inférieur à 2 mm. Le dispositif conforme à l'invention est avantageusement utilisé en liaison avec des lampes d'éclairage.
