Problems solved by technology

The luminous powder with radioactivity is mixed with radioactive substances in the fluorescent powder, and the ray emitted by the radioactive material is used to excite the fluorescent powder to emit light. This kind of luminous powder has a long luminescence time, but because of its toxicity, harmfulness and environmental pollution, it is widely used. Small
In the production process of energy-saving lamps, it is also necessary to coat fluorescent powder in the lamp tube to improve the luminous effect of energy-saving lamps, but the processing method of the fluorescent powder of energy-saving lamps currently provided is complicated, and the luminous efficiency of processed phosphors is not uniform.

Abstract

The invention relates to energy-saving lamp fluorescent powder which consists of a component A, a component B and a component C, wherein the component A consists of Y2O3, BaCO3, MgO and MoO3 by weight; the component B consists of Sb2O3, CaF2, BaO.Al2O3 and SrCO3; and the component C consists of CaHPO4, Na2B4O7 and Y2O3. The energy-saving lamp fluorescent powder provided by the invention is uniform in luminous effect, high in luminous stability and high in luminous strength during use, and the luminous flux of the manufactured energy-saving lamp can be 75lm / w. Moreover, the processing method of the fluorescent powder is simple, dry gas protection is used in the processing process and during subsequent treatment, the drying step is eliminated, and the processing time consumption is low.

Description

technical field [0001] The invention belongs to the field of luminescent materials, and in particular relates to an energy-saving lamp fluorescent powder. Background technique [0002] Phosphor powder is usually divided into two types: photoluminescent energy storage luminous powder and radioactive luminous powder. Photo-energy storage luminous powder is a fluorescent powder that stores light energy after being irradiated by natural light, daylight, ultraviolet light, etc., and then slowly releases it in the form of fluorescence after stopping the light irradiation, so it can be used at night or in dark places. , can still see the luminescence, which lasts for several hours to more than ten hours. The luminous powder with radioactivity is mixed with radioactive substances in the fluorescent powder, and the ray emitted by the radioactive material is used to excite the fluorescent powder to emit light. This kind of luminous powder has a long luminescence time, but because of ...
