Abstract

Le présent modèle d'outil concerne une lampe incorporée ignifuge et un logement de lampe ignifuge, la lampe incorporée ignifuge comprend un logement de lampe, un dispositif de source de lumière, et un dispositif ignifuge. Le dispositif de source de lumière et le dispositif ignifuge sont tous deux disposés dans un espace interne du logement de lampe, et le dispositif ignifuge sépare l'espace intérieur du logement en un espace inférieur et un espace supérieur. La lampe incorporée ignifuge comporte en outre au moins un canal de dissipation thermique, et chacun des canaux de dissipation thermique communique avec l'espace inférieur et l'espace supérieur pour permettre que la chaleur générée par le dispositif de source de lumière rayonne de l'espace inférieur vers l'espace supérieur par chacun des canaux de dissipation thermique. Après avoir subi une expansion, le dispositif ignifuge scelle chacun des canaux de dissipation thermique pour empêcher que l'espace inférieur et l'espace supérieur communiquent par les canaux de dissipation thermique.
