摘要： A ceramic envelope for a high intensity discharge lamp employs the ceramic envelope obtained by integrally forming each electrode insertion section and at least an end portion of a barrel section. An elliptical barrel section forms a discharge space and capillary sections are for insetting and fixing a discharge electrode. Further, the capillary sections protrude outwardly from both ends of the barrel section, while facing each other. The ceramic envelope mainly consists of alumina and is burned to exhibit light transmittable properties. Moreover, a boundary of the end portion corresponding to a corner of the discharge space, between the barrel section and each of the capillary sections is formed to have a radius of curvature of 1.0 mm. The ceramic envelope is capable of reducing light color changes of the discharge lamp and is capable of extending the service life of the lamp.

摘要翻译： 用于高强度放电灯的陶瓷外壳采用通过一体地形成每个电极插入部分和至少一个筒部分的端部而获得的陶瓷封套。 椭圆筒形部分形成放电空间，毛细管部分用于排放和固定放电电极。 此外，毛细管部分从筒部的两端向外突出，同时彼此面对。 陶瓷外壳主要由氧化铝组成，被烧成具有透光特性。 此外，与筒体部和毛细管部之间的放电空间的角部对应的端部的边界形成为具有1.0mm的曲率半径。 陶瓷外壳能够减少放电灯的光色变化，并且能够延长灯的使用寿命。

摘要： A low pressure arc discharge lamp with an end-of-life structure is described. The lamp has a discharge tube with sealed ends, and the sealed ends contain a filament for forming a discharge arc. The filament is supported by lead-in wires. The discharge lamp further comprises a connecting element made of an insulating material which transversely connects the lead-in wires within the discharge tube. The transverse dimension of the connecting element is chosen so as not to allow the discharge arc beyond the connecting element upon end-of-life of the discharge lamp.
