Abstract

L'invention concerne un accessoire de lampe ignifuge de forme cylindrique comprenant une plaque de support (1) et un abat-jour de forme cylindrique (2). Une source de lumière et une base de la lampe sont montées dans l'abat-jour dans lequel est formé un trou traversant. Un conduit (3) est monté dans le trou traversant, un fil électrique (5) s'étendant de la base de la lampe se raccorde à l'équipement électrique à l'extérieur de l'abat-jour par le conduit (3). Un matériau ignifuge et/ou un matériau intumescent ignifuge (4) est placé à l'intérieur du conduit (3) ou à proximité de l'extrémité du conduit dans laquelle passe le fil. L'abat-jour de forme cylindrique (2) peut être constitué d'une couche métallique recouverte d'une couche calorifuge ignifuge. Le matériau ignifuge et/ou le matériau intumescent ignifuge (4) peut empêcher le feu de s'échapper de l'espace se trouvant entre la paroi interne du conduit et entre le fil lorsque se produit un incendie, ce qui permet d'empêcher efficacement la propagation du feu alentour.
