带吸光涂层的电灯、用于这种涂层的前体悬浮体和制造这种灯的方法
摘要：
本发明描述了一种电灯，其具有石英玻璃灯容器(10)，该石英玻璃灯容器(10)容纳电元件(3，4)。该灯容器的局部具有吸光、非反射性涂层(11，12)。该涂层主要由铁、氧化铁、硅和二氧化硅组成，铁(化合物)和硅(化合物)的重量百分比的比例在0.17≤铁(化合物)/硅(化合物)≤12的范围，且硅和二氧化硅的重量百分比的比例在0.5≤硅/二氧化硅≤50的范围。
摘要（英）：

The present invention describes an electric lamp. The electric lamp has a quartz glass lamp vessel (10) in which an electric element (3,4) is accommodated. The lamp vessel locally has a light-absorbing, non-reflective coating (11,12). The coating mainly consists of iron, iron oxide, silicon, and silicon dioxide, the ratio of the weight percentages of iron compounds and silicon compounds being in the range of 0.17 <= iron compounds/ silicon compounds <= 12, and the ratio of the weight percentages of silicon and silicon dioxide being in the range of 0.5 <= silicon/ silicon dioxide <= 50.
