LOW-PRESSURE MERCURY VAPOR DISCHARGE LAMP AND APPARATUS FOR TREATMENT |
摘要 |
The low-pressure mercury vapor discharge lamp has a lamp envelope (10) enclosing, in a gastight manner, a discharge space provided with a filling of mercury and a rare gas. The lamp envelope comprises discharge means for maintaining a discharge in the discharge space. The lamp envelope transmits UV-light and is made of a black glass component. The composition of the black glass component is free of PbO and comprises, expressed as a percentage by weight, the following constituents: 65-70 % by weight of SiO<SUB>2</SUB>, 1.4-2.2 % by weight of Li<SUB>2</SUB>O, 1.5-2.5 % by weight of Na<SUB>2</SUB>O, 11-13 % by weight of K<SUB>2</SUB>O, 1.8-2.6 % by weight of MgO, 2.5-5 % by weight of CaO, 2-3.5 % by weight of SrO, 8-9.5 % by weight of BaO, 0.2-0.4 % by weight of CoO, and 1.7-3.25 % by weight of NiO. The low-pressure mercury vapor discharge lamp is preferably used in an apparatus for treatment with radiation for personal care. |
