Description
Technical field
The present invention relates to the manufacturing technology of power saving fluorescent lamps, be specially a kind of low-mercury energy-saving lamp manufacturing process.
Background technology
In general, present home-use electricity-saving lamp low-pressure gaseous discharge lamp, mainly rely on mercury vapor discharge to produce ultraviolet deexcitation phosphor powder layer and send visible light for illumination.Yet, as everyone knows, mercury is a kind of noxious substance, its production link at electricity-saving lamp and scrap after all can be because volatilizing mercury to environment, bring harm for human body and environment, wherein, European Union just requires the mercury content of every energy-conservation fluorescent tube must be less than 5 ㎎ in forcing the ROHS instruction.Yet in actual production process, mercury can be decayed due to the use of fluorescent tube, cause its actual addition often to be greater than theoretical amount, and China also not yet sets up effectively useless lamp recovery system, these all make useless lamp become a large mercury pollution source, and the mercury pollution problem that how to reduce the fluorescent tube of all kinds of use liquid mercury becomes a problem in the urgent need to address of relevant environmental administration.
Summary of the invention
Technical problem solved by the invention is to provide a kind of low-mercury energy-saving lamp manufacturing process, to solve the shortcoming in the above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of low-mercury energy-saving lamp manufacturing process comprises following operating procedure:
1, fluorescent tube elongated and bend and make it to become U-shaped pipe in centre position, can when not increasing too much lamp body footprints, effectively pull open the horizontal irradiated area of fluorescent tube like this, avoid simultaneously the problem of helical lampl heat radiation inequality and the mutual shading of upper and lower adjacent tubes section.
2, at the inner surface of tube, utilize film applicator to apply one deck nano magnesia or alumina protective layer; the thickness of this metal oxide diaphragm is 300 ~ 500 μ m; then in the U-shaped pipe processed, utilize the powder coating machine dusting, make phosphor slurry evenly be coated on the metal oxide diaphragm of inner surface of tube wall.
3, fluorescent tube is placed in to the round type tube-baking machine, regulating baking temperature subregion ，Qie Ge district temperature is that a parabola changes, its peak value is 1080 ℃, under this roasted tube condition, can make finished product fluorescent tube light surface temperature reach 600 ℃, optical attenuation was controlled in 3% in 500 hours.
4, filament is installed in fluorescent tube, filament adopts the long-life filament that the main and auxiliary type hot(test)-spot temperature is low, surface is heated soon, easily start, and before being installed, filament need on filament, plate one deck silicon nitride coating, coating layer thickness is below 20 μ m, and at a process using water applying electronic powder that stretches tight, reduce other auxiliary material, in order to can improve class vacuum rate when the exhaust.
5, by rare gas and for by electric discharge, producing ultraviolet mercury seal, be contained in a U-shaped slowly-releasing groove, slowly-releasing groove end face opening and at the openend overlay film, this film decomposes after energising, by the mercury vapour atomization and be full of the fluorescent tube space.
6, in exhaust air technique, adopt the secondary glass degassing process, to improve the tubing vacuum, reduce the consumption of tube load to mercury, under exhaust condition, utilize umbellate form compressing member sealing fluorescent tube one end, make to form gap between flexible valve body and lamp housing, the gas in lamp housing enters in exhaust apparatus in gap thus.
Beneficial effect: technique of the present invention is simple, production efficiency is high, greatly accelerated radiating rate, reduced the consumption of mercury, simultaneously, effective useful life of prolonging lamp tube, simple, reasonable compact, the easy accessibility of its fluorescent lamp overall structure of producing, and light conversion efficiency is high, is very beneficial for energy-conserving and environment-protective.
Embodiment
Below give an actual example and describe the present invention.
At first utilize bench fluorescent tube is elongated and bend and make it to become U-shaped pipe in centre position.After pipe machine-shaping, utilize film applicator to apply one deck nano magnesia or alumina protective layer at the inner surface of tube; the thickness of this metal oxide diaphragm is 500 μ m; then in the U-shaped pipe processed, utilize the powder coating machine dusting, make phosphor slurry evenly be coated on the metal oxide diaphragm of inner surface of tube wall.
Fluorescent tube is placed in to the round type tube-baking machine, regulate baking temperature and be divided into the Wu Ge district, in the present embodiment, five subregions are respectively 380 ℃, 560 ℃, 1080 ℃, 760 ℃ and 480 ℃, under this roasted tube condition, can make finished product fluorescent tube light surface temperature reach 600 ℃, optical attenuation was controlled in 3% in 500 hours.
Filament is installed in fluorescent tube, filament adopts long-life alloy tungsten filament as filament, and before being installed, filament need on filament, plate one deck silicon nitride coating, coating layer thickness is 18 μ m, and at a process using water applying electronic powder that stretches tight, reduce other auxiliary material, in order to can improve class vacuum rate when the exhaust.
By rare gas and for by electric discharge, producing ultraviolet mercury seal, be contained in a U-shaped slowly-releasing groove, slowly-releasing groove end face opening and at the openend overlay film, this film decomposes after energising, by the mercury vapour atomization and be full of the fluorescent tube space.
In exhaust air technique, adopt the secondary glass degassing process, to improve the tubing vacuum, reduce the consumption of tube load to mercury, under exhaust condition, utilize umbellate form compressing member sealing fluorescent tube one end, make to form gap between flexible valve body and lamp housing, the gas in lamp housing enters in exhaust apparatus in gap thus.
