Abstract:

Low-pressure mercury vapor discharge lamp has an at least partly substantially cylindrical discharge vessel (10) with a length Ldv and with an internal diameter Din. The discharge vessel (10) encloses, in a gastight manner, a discharge space (13) provided with a inert gas mixture and with mercury. The discharge vessel (10) comprises discharge means (electrodes 20a; 20b) for maintaining a discharge in the discharge space (13). According to the invention, the ratio of the weight of mercury mHg in the discharge vessel (10) to the product of the internal diameter Din and the length of the discharge vessel Ldv is given by the relation: Formula (I), wherein C≦0.01 μg/mm2. Preferably, 0.0005≦C≦0.005 μg/mm2. Preferably, the discharge vessel (10) contains less than 0.1 mg mercury. The discharge lamp according to the invention operates under unsaturated mercury conditions. m Hg D in × L dv = C ( 1 )

Abstract(Chinese):

低压汞蒸汽放电灯具有至少部分基本上圆柱形的放电容器（10），其长度为L dv且内径D 。放电容器（10）以气密的方式包围设置有惰性气体混合物和汞的放电空间（13）。放电容器（10）包括用于保持放电空间（13）中的放电的放电装置（电极20a; 20b）。根据本发明，放电容器（10）中的汞汞Hg重量与中的内径D ：式（I），其中C <=0.01μg/ MM 2。优选地，0.0005 <= C <=0.005μg/ MM 2。优选地，放电容器（10）含有小于0.1mg的汞。根据本发明的放电灯在不饱和汞条件下工作。 $\begin{matrix} 在x中_{（1）MATH>Information query Global Dossier EspacenetIPC分类: H 电学 H01 基本电气元件 H01J 放电管或放电灯（火花隙入H01T；消耗电极的弧光灯入H05B；粒子加速器入H05H） H01J61/00 气体放电或蒸气放电灯（有消耗电极的弧光灯入H05B；场致发光灯入H05B) H01J61/02 .零部件 H01J61/12 ..充气物质的选择；特定的工作压强或温度 H01J61/18 ...由金属蒸气为主要成分的 H01J61/20 ....水银蒸气Find Agent Technical Fields Latest Chinese Patents Latest US Patents Semantic Search newFriend Links 专利交易门类知识网企业财务服务中科微点API Changelog WeChat Group © 2025 Shanghai Xiaoyi Network Technology Co., Ltd. .
