Patentansprüche:Patent claims: 1. Elektrode für eine Hochdruck-Gas- und/oder -Dampfentladungslampe, die gasdicht durch die aus hochschmelzendem Glas, z. B. 1. Electrode for a high-pressure gas and / or vapor discharge lamp that is gas-tight through the refractory glass, e.g. B. Quarzglas, bestehende Lampenwand geführt ist, stabförmig ist und aus zwei elektrisch in Reihe geschalteten Teilen besteht, von denen der durch die Lampenwand geführte Teil aus reinem Wolfram und der sich daran anschließende, im Innern der Lampe liegende Teil aus thoriertem Wolfram besteht, wobei die zwei Elektrodenteile lediglich durch ein Lötmaterial aus Molybdän oder einer Molybdänlegierung, deren Schmelzpunkt erheblich höher als die Erweichungstemperatur des Glases liegt, miteinander verbunden sind, nach Patent 15 89 241, dadurch gekennzeichnet, daß der Abstand der beiden einander gegenüberliegenden Enden der Elektrodenteile (1,Quartz glass, existing lamp wall is guided, rod-shaped and made of consists of two parts connected electrically in series, of which the part passed through the lamp wall made of pure tungsten and the adjoining part inside the lamp Thoriated tungsten consists, with the two electrode parts only made of a solder Molybdenum or a molybdenum alloy, the melting point of which is considerably higher than the softening temperature of the glass is connected to each other, according to Patent 15 89 241, characterized in that that the distance between the two opposite ends of the electrode parts (1, 3) und damit die Dicke der Lötmaterialschicht (2) von der Stelle des kleinsten Abstandes zwischen den Elektrodenteilen her nach außen stetig zunimmt.3) and thus the thickness of the soldering material layer (2) from the point of the smallest distance between the electrode parts steadily increases towards the outside. 2. Elektrode für eine Hochdruck-Gas- und/oder -Dampfentladungslampe nach Anspruch 1, dadurch gekennzeichnet, daß die einander zugewandten Enden der Elektrodenteile an einem Punkt oder auf einer geraden Linie aneinander anliegen.2. Electrode for a high pressure gas and / or vapor discharge lamp according to claim 1, characterized characterized in that the mutually facing ends of the electrode parts at a point or on lie against each other in a straight line. 3. Elektrode für eine Hochdruck-Gas- und/oder -Dampfentladungslampe nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß mindestens eines der einander zugewandten Enden der Elektrodenteile abgerundet ist.3. Electrode for a high pressure gas and / or vapor discharge lamp according to claim 1 or 2, characterized in that at least one of the mutually facing ends of the electrode parts is rounded. 4. Elektrode für eine Hochdruck-Gas- und/oder -Dampfentladungslampe nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß mindestens eines der einander zugewandten Enden der Elektrodenteile keilförmig abgeschrägt ist.4. electrode for a high pressure gas and / or vapor discharge lamp according to claim 1 or 2, characterized in that at least one of the mutually facing ends of the electrode parts is beveled in a wedge shape.
