Abstract

La présente invention concerne un corps de refroidissement destiné à une lampe, ledit corps de refroidissement présentant un premier segment (2) plat au moins aux premiers abords, ainsi qu'un second segment (4) plat au moins aux premiers abords, le second segment (4) étant relié au premier segment (2) directement, et ainsi de sorte que le second segment (4), lorsque le premier segment (2) est orienté horizontalement, s'étend verticalement vers le haut au moins sensiblement à partir d'une zone intermédiaire (6) du premier segment (2), à savoir, mesuré depuis une zone de surface (8) du premier segment (2), orientée vers le haut, sur une dimension verticale (V). Selon l'invention, le corps de refroidissement est conçu de sorte que, lorsqu'on le considère dans une coupe verticale à travers le premier segment (2) et le second segment (4), il ne présente, hors du second segment (4), aucune partie qui se trouve au-dessus d'un niveau (TV) fixé par la moitié de la dimension verticale (V), de préférence le quart de la dimension verticale (V). Cette conception permet de réaliser des surfaces du corps de refroidissement comparativement importantes, par lesquelles peut s'effectuer dans une première ligne une évacuation de chaleur par rayonnement. Le fait que dans une zone située latéralement autour du second segment (4) ne se trouve aucune autre partie du corps de refroidissement, permet d'obtenir une évacuation de chaleur (Ä) des parties de surfaces du second segment (4) pratiquement sans entraves. En particulier, cette évacuation de chaleur latérale n'est pas entravée par des nervures de refroidissement ou autres parties. L'émission de chaleur vers le haut par le premier segment (2) peut également s'effectuer sans entrave. L'invention concerne également un agencement de module de lampe, au moins une DEL (2) étant montée sur un corps de refroidissement de ce type, ainsi qu'une lampe correspondante.
