Abstract

Ein keramisches Entladungsgefäß für eine Hochdruckentladungslampe ist aus einem zylindrischen Mittelteil und zwei halbkugelförmigen Endstücken gebildet, wobei die Länge des Mittelteils kleiner oder gleich dem Radius der Endstücke gewählt ist. Dadurch wird die Isothermie des Entladungsgefäßes verbessert.
