HIGH-PRESSURE DISCHARGE LAMP

摘要

High-pressure discharge lamp which is provided with a discharge vessel which encloses a discharge space. The discharge vessel has a ceramic wall and is closed by a ceramic plug. An electrode which is located inside the discharge space is connected to an electric conductor by way of a leadthrough element. The leadthrough element projects through the ceramic plug with a close fit and is connected thereto in a gastight manner by way of a sealing ceramic. The leadthrough element has a first part which is formed by a cermet at the area of the gastight connection. The leadthrough element has a second part which is a metal part which extends from the cermet in the direction of the electrode.
