Abstract

Dans un module d'éclairage à diodes (10) comportant une matrice de diodes (12) montée sur une plaque support (14) et des moyens de dissipation de la chaleur dégagée par la matrice de diodes, il est prévu une plaque métallique (22) dont une face externe est en contact avec cette plaque support et une face interne supporte une mousse métallique alvéolaire (24) et un boîtier formant cuve (26) rempli par la mousse métallique alvéolaire et dont la plaque métallique constitue le couvercle, le boitier comportant des orifices d'entrée et de sortie traversant le boitier pour recevoir un liquide de refroidissement et un séparateur (28) définissant dans la mousse métallique alvéolaire deux zones séparées de circulation pour le fluide de refroidissement, une zone d'amenée du fluide de refroidissement et une zone de reflux du fluide de refroidissement, le passage de l'une à l'autre zone s'effectuant au niveau d'une découpe (28A) du séparateur.
