    • A high pressure discharge lamp may include a ceramic discharge vessel and a longitudinal axis, wherein at least one electrode is led out of the discharge vessel by means of a metal-containing feed-through, wherein the feed-through is connected to one end of the discharge vessel by way of a ceramic-containing adjustment part, wherein the adjustment part is tubular and consists of individual layers with different compositions, at least two materials A and B forming a plurality of layers of the adjustment part, these materials being chosen such that their coefficient of thermal expansion is between that of the feed-through and that of the end of the discharge vessel or at most is just outside, the layer thickness of each layer being so low that no shearing forces can occur, and the layer thickness of each layer of the same material being different.
    • 高压放电灯可以包括陶瓷放电容器和纵向轴线,其中至少一个电极通过含金属的馈通引出放电容器,其中馈通连接到 所述放电容器通过含陶瓷的调节部件,其中所述调节部件是管状的,并且由具有不同成分的各个层组成,至少两种材料A和B形成所述调节部件的多个层,这些材料被选择为 它们的热膨胀系数在馈通和放电容器末端的热膨胀系数之间,或者至多在外侧,每层的层厚度如此之低,不会产生剪切力,层厚度 相同材料的每层不同。
