[0004] In addition, the existing anti-ultraviolet products, such as anti-ultraviolet glass, anti-ultraviolet film and anti-ultraviolet glasses, etc., although they can absorb ultraviolet rays to a certain extent, they also absorb a large amount of visible light, which makes their performance unable to meet people's pursuit of environmental protection "green lighting". need

Embodiment 1

[0027] in such as Figure 5 The ZnO thin film was prepared on the clean spiral energy-saving lamp shown.

[0028] 1) configuration of zinc oxide thin film solution: 32g zinc acetate is dissolved in the mixed solution of 180ml ethylene glycol methyl ether and 10ml glacial acetic acid, then add 10ml and zinc acetate equimolar ethanolamine, obtain the solution that total volume is 200ml, in After 1.5h stirring at 80°C until the Zn + The concentration is 0.8mol / L to form a transparent and homogeneous solution;

[0029] 2) Cleaning of the lamp tube and removal of surface impurities (oil stains, impurity ions, etc.): Use deionized water with a resistivity of 16MΩ.cm and alcohol with a purity of more than 99% to ultrasonically, 3 to 4 times each, 3 minutes each time , followed by soaking in acetic acid solution with a concentration of 3% to 5% for 30s, and using high-purity N with a purity of 99.99% 2 blow dry;

[0030] 3) Throw glue to form a film: Pour the solution prepared in ...

Embodiment 2

[0035] Steps 1) to 3) are the same as in Example 1, the heat treatment temperature in step 4) is 250° C., and the heat treatment time is 3 hours, and then phosphor coating is performed on the zinc oxide film.

Embodiment 3

[0037] Steps 1) to 3) are the same as in Example 1, the heat treatment temperature in step 4) is 300° C., the heat treatment time is 2 hours, and then phosphor coating is performed on the zinc oxide film.

Abstract

The invention provides an ultraviolet protective energy-saving lamp tube. A zinc oxide film is plated on the inner surface of an energy-saving lamp tube, thus the harm on people from the ultraviolet radiation of an energy-saving lamp is reduced, and the shortage that the traditional ultraviolet resisting products can not absorb a great deal of visible light is overcome. A method for treating the inner surface of the energy-saving lamp tube disclosed by the invention comprises the step of preparing a ZnO film with a micro-nano structure on the inner surface of the energy-saving lamp tube by a sol-gel spin-coating technique, wherein the obtained energy-saving lamp has low light transmission rate within the ultraviolet band, the light transmission rate within the ultraviolet band can be below 10%, and the light transmission rate within the visible light band is as high as 90%. The invention has the advantages that the ZnO film and fluorescent powders can be greatly fixed and do not undergo the chemical reaction; the cost is low; and the ultraviolet protective energy-saving lamp tube can be better compatible with the production process of the energy-saving lamp and can take the place of the traditional Al2O3 protective film.

Description

technical field [0001] The invention belongs to the field of materials, especially the field of new energy materials, and specifically relates to an energy-saving lamp tube with good ultraviolet protection function. Background technique [0002] Our country has listed the "green lighting project" as a key promotion project and a cross-century strategy for the energy-saving industry. The green lighting products that are developed and popularized include compact fluorescent lamps with high efficiency and energy saving. However, due to the defect of its luminescence principle (mercury atoms absorb energy and transition to ionize, emit 253.7nm ultraviolet rays, and ultraviolet rays excite phosphors to emit light), ultraviolet radiation will inevitably be generated. Especially when irradiated at close range, the ultraviolet radiation is stronger. Although there is an isolation film between the inner surface of the glass tube and the phosphor as a protective film layer, Al 2 o ...
