Title
(EN) LAMP AND LAMP PACKAGE MADE OF FUNCTIONALLY GRADIENT MATERIAL
(FR) LAMPE ET ENVELOPPE DE LAMPE FABRIQUEE DANS UN MATERIAU A GRADIENT FONCTIONNEL
Abstract
(EN) A lamp package (10, 30) includes a sealing member consisting of a functionally gradient material, and a lead rod (13, 32) bonded to the sealing member (11, 31), which is a laminate of insulating inorganic substance layers and a plurality of compound layers consisting of a conductive inorganic component and an insulating inorganic component. In the sealing member, the proportion of the conductive organic component increases in the direction of lamination and a hole is formed extending in the same direction to receive the lead rod. A sleeve made of refractory metal is inserted integrally between the hole and the lead rod. The package made of the functionally gradient material forms a hermetic enclosure of a lamp.
(FR) L'invention concerne une enveloppe de lampe (10, 30), comprenant un élément de scellement constitué d'un matériau à gradient fonctionnel, une tige conductrice (13, 32) reliée à audit élément de scellement (11, (31) constitué d'un stratifié de couches de substance inorganique d'isolation, et d'une pluralité de couches de composé constituées d'un composant inorganique conducteur et d'un composant inorganique d'isolation. Dans l'élément de scellement, la proportion du composant inorganique augmente dans le sens de la stratification, et un alésage est formé dans le même sens de façon à recevoir la tige conductrice. Un manchon de métal réfractaire est intégralement inséré entre l'alésage et la tige conductrice. L'enveloppe fabriquée dans le matériau à gradient fonctionnel forme un carter de lampe hermétique.
