Title
(EN) HIGH PRESSURE DISCHARGE LAMP AND PRODUCTION METHOD THEREOF
(FR) LAMPE A DECHARGE HAUTE PRESSION ET PROCEDE DE PRODUCTION CORRESPONDANT
Abstract
(EN) A high pressure discharge lamp includes a ceramic discharge tube (11) having an ionization light-emitting substance and a starting gas filled in the internal space (13) thereof, a closing member (50A) equipped with a through-hole (14a, 15a), at least a part of which is fixed to the inside of end portion (12) of the ceramic discharge lamp (11), a current conductor (5) equipped with an electrode system (9) and inserted into the through-hole (14a, 15a) of the closing member (50A), and a sealing material layer (16A) so formed as to be bonded to the closing member (50A) at portions other than the through-hole (14a, 15a) and to the current conductor (5). Preferably, the sealing material layer (16A) comprises a metallized layer.
(FR) La lampe à décharge haute pression de la présente invention comporte un tube céramique de décharge (11) pourvu d'une substance photoémettrice par ionisation et renfermant un gaz d'amorce à l'intérieur (13), un organe de fermeture (50A) pourvu d'un orifice traversant (14a, 15a), une pièce au moins étant fixée sur la face interne de l'extrémité (12) de la lampe céramique à décharge (11), un élément électro-conducteur (5) pourvu d'un système d'électrode (9) et inséré dans l'orifice (14a, 15a) de l'organe de fermeture (50A), et une couche en substance étanchéifiante (16A) réalisée de façon à adhérer d'une part à l'organe de fermeture (50A), en des endroits différents de l'orifice traversant (14a, 15a), et d'autre part à l'élément électro-conducteur (5). La couche de substance étanchéifiante (16A) comprend de préférence une couche métallisée.
