Electric lamp having a coated external current conductor |
摘要 |
The electric lamp comprises a lamp vessel (1) and an electric element (4). The electric element is electrically connected to the exterior via a current feed-through comprising an external current conductor (7). By covering the external current conductor with a protective coating (8) contains chromium which can react with SiO2 to form low-melting phases, the lifetime of the lamp is increased significantly.
