Description
Technical field
The invention belongs to the electric light source technology field, be specifically related to a kind of core column for low-voltage discharging lamp.
Background technology
Low-pressure discharge lamp is widely used in room lighting, and its used stem stem is that the sealing-in seal wire burn-back that is complementary by glass horn pipe, glass air exhaust rod, with the aforementioned glass workpiece coefficient of expansion forms, and liquid mercury is housed in the air exhaust rod when stem stem and fluorescent tube are packaged into discharge lamp.Be generally used for making in the glass material of stem stem and all contain a certain proportion of lead, plumbous and liquid mercury can cause environmental pollution, threatening human health, therefore use the glass material of unleaded composition, solid pilulae hydrargyri to make low-pressure discharge lamp, is the inevitable development trend of such electric light source products.If also use the stem stem of original structure to make low-pressure discharge lamp, the solid pilulae hydrargyri can't be spacing in air exhaust rod, may roll out to fluorescent tube from the stem stem steam vent, influenced the useful life of low-pressure discharge lamp.
Summary of the invention
The invention provides a kind of core column for low-voltage discharging lamp, use the solid pilulae hydrargyri when it and fluorescent tube are packaged into discharge lamp, this stem stem can carry out spacing to pilulae hydrargyri, has guaranteed the luminous flux of fluorescent tube, shorten the take-off time of fluorescent tube, prolonged the useful life of low-pressure discharge lamp.
The present invention is achieved in that a kind of core column for low-voltage discharging lamp, the sealing-in seal wire burn-back that it is complementary by glass horn pipe, glass air exhaust rod, with the aforementioned glass workpiece coefficient of expansion forms, sealing-in seal wire and nickel wire welding are drawn, be positioned at the air exhaust rod leading portion through hole at oviduct loudspeaker position, its minimum diameter is less than the used pilulae hydrargyri diameter of low-pressure discharge lamp, and its maximum inner diameter is greater than the used pilulae hydrargyri diameter of low-pressure discharge lamp.
Among the present invention, described glass glass horn pipe, glass air exhaust rod are to be made by crown glass, and its component weight proportion is as follows:
SiO
2 62.0-68.0％；K
2O 5.0-7.0％；Na
2O 10.0-15.0％；
Al
2O

CeO
2 0.1-0.4％； Fe
2O
3 0-0.2％； BaO 0-10.4％； SrO 0-4.0％。
The sealing-in seal wire is that driving fit setting-in dilval rod forms in oxygen-free copper pipe, and both weight proportions are as follows: dilval rod 55%-65%, and oxygen-free copper pipe 35%-45%, both total amounts satisfy 100%.
For satisfying the air exhaust rod leading portion through hole requirement at loudspeaker position, can with cylindrical tube to flat in the wall to folder, form the flat ellipse through hole; Perhaps the sidewall with cylindrical tube inwardly pushes, and forms D shape through hole.
After adopting as above technical scheme, glass horn pipe and air exhaust rod use crown glass to make, and do not contain poisonous lead element, can not cause environmental pollution.The sealing-in seal wire is that driving fit setting-in dilval rod forms in oxygen-free copper pipe, and its coefficient of expansion is consistent with crown glass, during encapsulation and crown glass be complementary, realize the good air-tightness sealing-in.The air exhaust rod leading portion through hole that is positioned at the loudspeaker position is not a regular shape, and its minimum diameter is less than the pilulae hydrargyri diameter, and pilulae hydrargyri can't pass through this section air exhaust rod, preventing pilulae hydrargyri play in air exhaust rod, even rolls out in the fluorescent tube from the stem stem steam vent; Its maximum inner diameter has certain interval greater than the diameter of pilulae hydrargyri between pilulae hydrargyri and air exhaust rod through hole, guarantees to charge into the unimpeded of argon gas.By the variation of said structure, can improve the luminous flux of low-pressure discharge lamp, shortened the take-off time of fluorescent tube, prolonged the useful life of fluorescent tube.In order to satisfy the requirement of loudspeaker position air exhaust rod leading portion through hole, air exhaust rod can be used cylindrical tube, with this section cylindrical tube wall is inwardly flattened, forms the flat ellipse through hole, also a wall of this section cylindrical tube inwardly can be squeezed into D shape through hole.One-sided extruding cylinder tube wall can be enhanced productivity.
