Abstract

L'invention concerne un module DEL protégé contre les explosions, lequel présente au moins une diode électroluminescente (2), un corps de refroidissement (3) relié à celle-ci et une couverture de DEL (5) recouvrant les DEL au moins dans le sens de rayonnement. La couverture de DEL (5) s'étend jusque dans une cavité d'enfichage (6) du corps de refroidissement (3). Dans cette cavité d'enfichage, la couverture de DEL est entourée par une masse de scellement (7) qui rend les DEL étanches par rapport à une atmosphère extérieure et éventuellement explosive. De ce fait, un module DEL protégé contre les explosions peut être produit, sa fabrication étant relativement simple et possible en peu de temps à peu de frais à partir de pièces préfabriquées. Dans le même temps, le module DEL protégé contre les explosions est également caractérisé en ce qu'un refroidissement suffisant correspondant au type de protection d'allumage "sécurité intrinsèque" et un enrobage de l'élément correspondant au type de protection d'allumage "encapsulage" sont donnés.
