具有无汞气体填充物的低压蒸气放电灯
摘要：
本发明涉及低压蒸气放电灯，包括透辐射放电灯管(1)，所述放电灯管以气密方式封闭具有气体填充物的放电空间(3)。所述气体填充物基本不含汞，而包括铟化合物和缓冲气体。所述放电灯管(1)包括用于在所述放电空间(3)中维持气体放电的放电装置(2)。所述放电灯管(1)具有发光层(4)。所述发光层(4)包括基于次氮基硅酸盐或基于氧代次氮基硅酸盐的发光材料。优选，所述发光材料包括稀土发射体。优选，所述发光材料包括铕、铈或镱发射体。
摘要（英）：

A low-pressure vapor discharge lamp has a radiation-transmitting discharge vessel (1) enclosing, in a gastight manner, a discharge space (3) provided with a gas filling. The gas filling is substantially free of mercury and comprises an indium compound and a buffer gas. The discharge vessel (1) comprises discharge means (2) for maintaining a gas discharge in the discharge space (3). The discharge vessel (1) is provided with a luminescent layer (4). The luminescent layer (4) comprises a luminescent material based on a nitridosilicate or on an oxonitridosilicate. Preferably, the luminescent material comprises rare-earth emitters. Preferably, the luminescent material comprises europium, cerium, or ytterbium emitters.
