Abstract
The invention discloses a low-mercury long-life energy-saving lamp, comprising a lamp holder and a lamp tube connected with the lamp holder. The lamp tube comprises a glass wall, a protective film coated on the inner wall of the glass wall, and a phosphor layer coated on the protective film; solid amalgam is arranged in the lamp tube. The low-mercury long-life energy-saving lamp has the following advantages that: due to adoption of the solid amalgam instead of mercury, a. loss and diffusion of the mercury are effectively avoided during the process of producing, and pollution to the air environment caused by damage and abandonment of the product is obviously lightened; b. the amalgam has the same operation characteristics as that of the mercury, the best light output of the lamp can be ensured; and c. the actual amount of mercury filled in the lamp tube can be effectively controlled only by controlling granular size and weight of the amalgam. The consumption of the mercury is reduced by taking pre-coated nano-alumina as the protective film; and through combination with long-life cathode materials, the low-mercury long-life energy-saving lamp with 0.7-1 mg mercury is manufactured, thereby contributing to environmental protection.
Description
Technical field
The present invention relates to low mercury long-life energy-saving lamp.
Background technology
Electricity-saving lamp belongs to low-pressure gaseous discharge lamp, and its relies on mercury vapor discharge to produce ultraviolet deexcitation phosphor powder layer and sends visible light and be used to throw light on.Mercury is kind of a poisonous and harmful substance, at production link, product breakage or scrap Shi Douhui environment is polluted, brings harm to health, growing along with the electricity-saving lamp consumption, and the problem of mercury pollution obtains attention in the industry all the more.
It is very limited to keep the required mercury amount of electricity-saving lamp discharge in theory, actual amount but is higher than theoretical value far away, and this is because lamp needs constantly to consume mercury in the burning-point process, and effectively mercury is exhausted in lamp, lantern festival is died of old age because lack mercury, therefore focuses on controlling mercury consumption.European Union forces the mercury content of ROHS command request electricity-saving lamp to prop up less than 5mg/, and various countries also limit with reference to the mercury use of this instruction to electricity-saving lamp substantially.In 200810037089.3 patents, by tube inner wall being carried out coating with amorphous nano titanium oxide water thin liquid or with brockite shape titanium dioxide water thin liquid, reduce electricity-saving lamp in use to the consumption of mercury, produced the low-mercury energy-saving lamp of mercury content between 0.8 milligram to 1.4 milligrams.This 200810037089.3 patent also has following deficiency: 1, mercury content also needs further to reduce; 2, liquid mercury volatile quantity is big, and is mobile strong, more serious to the pollution of environment.3, not definition of the life-span of electricity-saving lamp.
