Abstract: A voidless CMH lamp and a method of making such a lamp are provided. The CMH lamp includes a lamp body that receives at least one end plug. The end plug is constructed from a core of cermet material received within an outer layer of a ceramic material. An electrode is placed into the cermet material. The application of heat causes the cermet material to contract and eliminate voids between the lamp and cermet material. Co-sintering of the lamp, core, and outer layer provides a hermetic seal without necessarily using e.g., a sealing frit. Sintering of the ceramic material surrounding the cermet can be also used to improve light output and photometric performance of the lamp. The creation of one or more openings or recesses in the end plug can also provide performance improvements.

Abstract translation: 提供无孔CMH灯和制造这种灯的方法。 CMH灯包括容纳至少一个端塞的灯体。 端塞由容纳在陶瓷材料的外层内的金属陶瓷材料的芯构成。 将电极放置在金属陶瓷材料中。 热的应用导致金属陶瓷材料收缩并消除灯和金属陶瓷材料之间的空隙。 灯，芯和外层的共烧结提供气密密封，而不必使用例如密封玻璃料。 围绕金属陶瓷的陶瓷材料的烧结也可用于改善灯的光输出和光度性能。 在端塞中产生一个或多个开口或凹槽也可以提供性能改进。
