Abstract

La présente invention porte sur un module de lampe à DEL, dans lequel module non pas le module DEL tout entier, mais seulement une lampe à DEL, peut être remplacée, et une fonction de rayonnement de chaleur augmentant de façon significative la durée de vie d'un produit par prévention d'un claquage par la décharge rapide d'une chaleur générée intérieurement est comprise, et sur un éclairage comprenant le module de lampe à DEL. Le module de lampe à DEL comprend une lampe à DEL configurée de façon à être détachable de façon indépendante et un module d'adaptation, de façon à avoir des nervures de rayonnement de chaleur formées sur une face externe de celui-ci, et à avoir la lampe à DEL montée de façon détachable sur celui-ci. Une chaleur générée dans le module de lampe à diodes électroluminescentes est facilement déchargée à l'extérieur par l'intermédiaire d'un trou de rayonnement de chaleur qui est formé quand les nervures de rayonnement de chaleur et un manchon d'adaptation sont couplées à un boîtier d'adaptation. Par conséquent, une fonction de rayonnement de chaleur peut être améliorée de façon significative.
