    • A compact fluorescent lamp has a low-pressure mercury-vapor discharge lamp (1) surrounded by a light-transmitting envelope (60) which is attached to a lamp housing (70). The low-pressure mercury vapor discharge lamp has a light-transmitting discharge vessel (10) enclosing, in a gastight manner, a discharge space (11) provided with a filling of mercury and a rare gas. The discharge vessel comprises discharge means for maintaining a discharge in the discharge space. The discharge vessel is provided with a luminescent layer (17) comprising a luminescent material. A surface of the light-transmitting envelope (60) is provided with a light-refraction layer (61) comprising a UV-absorbing refractive material with a high refractive index. Preferably, the UV-absorbing refractive material is Ti02, Nb 2 O5, Ta 2 O 5 , ZrO, Si 3 N 4 , ATO, ITO, or FTO. Preferably, the light-transmitting envelope (60) is provided with a diffusion layer (65).

    • A low-pressure mercury vapor discharge lamp is provided with a discharge vessel (10). The discharge vessel (10) encloses a discharge space (11) provided with a filling of mercury and a rare gas in a gastight manner. According to the invention, the discharge vessel is made from a glass comprising silicon oxide and sodium oxide in the following percentages by weight: SiO2 60 - 80 wt.% and Na2O 10 - 20 wt.%. Preferably, the glass composition comprises SiO2 70-75 wt.%, Na2O 15-18 wt.% and K2O 0.25-2 wt.%, so that this glass is a so-called sodium-rich glass as compared to the customarily used mixed alkali glass. At least a part of an inner surface of the discharge vessel (10) is provided with a transparent layer (16) comprising a borate or a phosphate of an alkaline-earth metal and/or of scandium, yttrium or another rare earth metal. Preferably, the alkaline-earth metal is calcium, strontium and/or barium. Preferably, the transparent layer (16) comprises yttrium borate and strontium borate. Preferably, the transparent layer (16) has a thickness between 5 nm and 200 nm. A luminescent layer (17) is preferably provided on top of the transparent layer in the discharge vessel. The discharge lamp according to the invention has a comparatively high maintenance.
    • 低压汞蒸气放电灯具有放电容器(10)。 放电容器(10)以气密的方式包围设置有汞和稀有气体的填充物的放电空间(11)。 根据本发明,放电容器由包含氧化硅和氧化钠的玻璃制成,重量百分比如下:SiO 2 60-80重量%,Na 2 O 10-20重量%。 优选地,玻璃组合物包含SiO 2 70-75重量%,Na 2 O 15-18重量%和K 2 O 0.25-2重量%,因此与常规使用的混合物相比,该玻璃是所谓的富钠玻璃 碱玻璃。 放电容器(10)的内表面的至少一部分设置有包含硼酸盐或碱土金属和/或钪,钇或其它稀土金属的磷酸盐的透明层(16)。 优选地,碱土金属是钙,锶和/或钡。 优选地,透明层(16)包括硼酸钇和硼酸锶。 优选地,透明层(16)的厚度在5nm和200nm之间。 发光层(17)优选设置在放电容器中的透明层的顶部。 根据本发明的放电灯具有较高的维护。
