  • Electric lamp with light-absorbing coating, precursor suspension for such a coating and method of making such a lamp
    Patent number: 8040065
    Abstract: An electric lamp is described, which has a quartz glass lamp vessel (10) accommodating an electric element (3, 4). 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.
