Ceramic lamp
First Claim
1. Ceramic lamp of translucent ceramic having a lamp vessel with a bulb portion and hermetically sealed tube portions connected to the bulb portion, electrically conductive supply components in the bulb portion, and hermetically sealing bodies of electrically conductive cermet weld on the hermetically sealed tube portions with a sealing material to form a hermetically sealed arrangement, base parts of the electrically conductive supply components held in the hermetically sealed bodies of electrically conductive cermet;
- wherein an intermediate layer is formed in a surface area of the hermetically sealing body, components of the electrically conductive cermet of the hermetically sealing body being intermixed with components of the sealing materials in said intermediate layer.

Abstract
A ceramic lamp in which the hermetically sealing bodies of electrically conductive cermet are sealed to hermetically sealed tube portions of the lamp vessel with a sealing material is arranged and provided with material components designed to give the hermetically sealing portions a high reliability. In particular, a lamp of a translucent ceramic has a lamp vessel which has a bulb portion and hermetically sealed tube portions which are connected to the bulb portion, and electrically conductive supply components in the bulb portion which have base parts inserted into the hermetically sealed bodies of electrically conductive cermet, is improved by seal welding of the hermetically sealing bodies of electrically conductive cermet on the hermetically sealed tube portion with a sealing material so that a hermetically sealed arrangement is produced in which, in the border area between the sealing material and the hermetically sealing body, an intermediate layer is formed in which components of the electrically conductive cermet of the hermetically sealing body are intermixed with components of the sealing materials.
