Patent

CA 2346523

A gas discharge lamp having a discharge vessel, for example composed of a base plate, front plate (2) and frame (3), has at least one closure element (6) which closes a discharge vessel opening in a gas-tight fashion by virtue of the fact that the closure element (6) was inserted into the discharge vessel opening and subsequently fused. The closure element (6) consists of a material which is low-melting by comparison with the remainder of the discharge vessel, for example sintered glass. It is possible to dispense with an additional connecting means between the closure element (6) and the adjacent wall of the discharge vessel (2).

L'invention concerne une lampe à décharge gazeuse comportant un récipient de décharge, comprenant par exemple une plaque de base, une plaque avant (2) et un cadre (3), qui présente au moins un élément de fermeture (6) fermant de manière étanche aux gaz une ouverture du récipient de décharge, du fait que l'élément de fermeture (6) a été introduit, puis fondu dans l'ouverture du récipient de décharge. Ledit élément de fermeture (6) consiste en un matériau à moindre point de fusion que le reste du récipient de décharge, par ex. en verre fritté. Ce système permet de ne plus avoir recours à un élément de jonction supplémentaire entre l'élément de fermeture (6) et la paroi adjacente du récipient de décharge (2).
