摘要:
The invention relates to a high-pressure discharge lamp (12), and a reflector lamp. The high-pressure discharge lamp has a discharge vessel (22, 61) enclosing a discharge space (24) which is provided with an ionizable filling comprising one or more halides. The discharge vessel is substantially constituted by a ceramic material (51, 52) having first and second end portions (33, 34). Current-supply conductors (44) issue through each end portion to respective electrodes (42) arranged in the discharge space (24) so as to maintain a discharge. At least one of the current-supply conductors is formed as a rod (44) comprising iridium. The rod is directly sealed to the ceramic material. Use of the iridium rod which is directly sealed to the ceramic material has theeffect that the interface between the rod and the ceramic material is strong and substantially free from cracks, resulting in a longer lifet ime of the high-pressure discharge lamp.
摘要(中):
本发明涉及一种高压放电灯(12)和一种反射灯。 高压放电灯具有封闭放电空间(24)的放电容器(22,61),放电空间(24)设置有包含一种或多种卤化物的可电离填充物。 放电容器基本上由具有第一和第二端部(33,34)的陶瓷材料(51,52)构成。 供电导体(44)通过每个端部分发送到布置在放电空间(24)中的各个电极(42)以维持放电。 至少一个供电导体形成为包含铱的棒(44)。 棒直接密封在陶瓷材料上。 使用与陶瓷材料直接密封的铱棒具有这样的作用,即棒与陶瓷材料之间的界面强并且基本上没有裂纹,导致高压放电灯的更长寿命。
