Abstract
The invention relates to a high-pressure discharge lamp comprising a discharge vessel enclosing a discharge space and provided with two main electrodes. Each of the main electrodes is connected to a lead-through element which is enclosed with an intermediate space by a closing part and is connected thereto in a gas-tight manner by means of a sealing joint. According to the invention, the lead-through element is provided with a protuberance reaching as far as the closing part and being present around the whole periphery of the lead-through element. In this manner, a screening of the sealing joint from the discharge space is obtained.
