Abstract: The discharge lamp (10) comprises a casing (20) made of glass, which surrounds the discharge vessel (16). The glass material of the casing is doped with sodium in a concentration of at least 10 ppm by relation to the weight, and preferably of at least 30 ppm. The glass material of the casing may contain, in addition to sodium, other alkali metals in a maximum concentration of totaling 25 ppm by relation to the weight. The discharge lamp comprises a socket (12) and a burner (14). The burner comprises a discharge vessel, lead wires (18), and a casing. The discharge vessel and the lead wires are formed as a single-piece glass body. Electrical conductors are in the lead wires, which are connected to electrodes (22) in the interior space of the discharge vessel. By the imposition of a voltage at the connections (24), which are connected to the electrodes, a gas discharge can be induced in the interior of the discharge vessel.

Abstract: A discharge lamp (10) has a discharge vessel (16) for generating an arc discharge between two electrodes (22) . The discharge vessel contains an inert gas, and metal halides. The lamp (10) further comprises an outer envelope (20) surrounding the discharge vessel. The outer envelope is made of transparent material containing Potassium in a maximum concentration of 10 ppm by relation to the weight. The metal halides are contained in the discharge vessel in an amount of 3-6 mug/mul of the inner volume of the vessel, preferably 5±0.5 mug/mul . The lamp exhibits an improved long term lumen maintenance and may have a physical, lifetime exceeding 4000 h net burning time.

Abstract translation: 放电灯（10）具有用于在两个电极（22）之间产生电弧放电的放电容器（16）。 放电容器含有惰性气体和金属卤化物。 灯（10）还包括围绕放电容器的外壳（20）。 外壳由透明材料制成，钾含量相对于重量最大为10 ppm。 金属卤化物以容积内容积为3-6mug / m 3的量容纳在放电容器中，优选为5±0.5mug / mul。 灯具具有改善的长期流明维持率，并且可能具有物理寿命超过4000小时的净燃烧时间。
