Abstract
The utility model discloses an energy saving lamp stem which is formed by sintering a lead-free glass horn trumpet (1),a lead-free glass exhaust rod (2) as well as a seal guide wire (3) matched with the swell factors of the glass pieces; the seal guide wire (3) and a nickel wire (4) are welded and led out; the through hole of the front section (5) of the exhaust rod arranged at the horn part of the horn trumpet is of D shape; the smallest inner diameter of the through hole is less than the diameter of a blue pill used by an energy saving lamp; the largest inner diameter thereof is larger than the diameter of the blue pill used by the energy saving lamp. A solid blue bill is used when the through hole is sealed with a lighting tube for discharging. The stem can carry out limitation on the blue pill, thus ensuring the luminous flux of the lighting tube, shortening the take-off time of the lighting tube and prolonging the service life of the energy saving lamp.
Description
Technical field
The utility model belongs to the electric light source technology field, is specifically related to a kind of electricity-saving lamp stem stem.
Background technology
Electricity-saving 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 electricity-saving 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 electricity-saving lamp, is the inevitable development trend of such electric light source products.If also use the stem stem of original structure to make electricity-saving 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 electricity-saving lamp.
Summary of the invention
The utility model provides a kind of electricity-saving lamp stem stem, uses the solid pilulae hydrargyri when it and fluorescent tube are packaged into electricity-saving lamp, and this stem stem can carry out spacing to pilulae hydrargyri, has guaranteed the luminous flux of fluorescent tube, has shortened the take-off time of fluorescent tube, has prolonged the useful life of electricity-saving lamp.
The utility model is achieved in that a kind of electricity-saving lamp stem stem, 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, the through hole that is positioned at the air exhaust rod leading portion at oviduct loudspeaker position is D shape, its minimum diameter is less than the used pilulae hydrargyri diameter of electricity-saving lamp, and its maximum inner diameter is greater than the used pilulae hydrargyri diameter of electricity-saving lamp.
In the utility model, the air exhaust rod leading portion at described loudspeaker position is that 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 air exhaust rod leading portion through hole that is positioned at the loudspeaker position is D 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 electricity-saving lamp, shortened the take-off time of fluorescent tube, prolonged the useful life of fluorescent tube.D shape through hole is that the wall with this section glass cylinder pipe inwardly pushes formation, and one-sided extruding cylinder tube wall can be enhanced productivity.

Embodiment
With reference to accompanying drawing, a kind of electricity-saving lamp stem stem of the utility model, sealing-in seal wire 3 burn-backs that it is complementary by crown glass oviduct 1, crown glass air exhaust rod 2, with the aforementioned glass workpiece coefficient of expansion form, and sealing-in seal wire 3 is drawn with nickel wire 4 welding.Air exhaust rod leading portion 5 through holes that are positioned at oviduct loudspeaker position are D shape through hole, and its minimum diameter is less than the used pilulae hydrargyri diameter of electricity-saving lamp, and its maximum inner diameter is greater than the used pilulae hydrargyri diameter of electricity-saving lamp, pilulae hydrargyri are carried out spacing, and guarantee that applying argon gas is unimpeded.D shape through hole is that the sidewall with cylindrical tube inwardly pushes formation.
The component weight proportion of crown glass oviduct, air exhaust rod is as follows:
SiO
2 62.0-68.0％；K
2O 5.0-7.0％；Na
2O 10.0-15.0％；
Al
2O
3 0-4.3％；CaO 2.5-6.2％；MgO 1.5-4.0％；B
2O
3 2.0-3.2％；
CeO
2 0.1-0.4％；Fe
2O
3 0-0.2％；BaO 0-10.4％；SrO 0-4.0％。
Sealing-in seal wire 3 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%.Dilval adopts 4J43 Dumet wire core dilval.Adopt crown glass oviduct 1, air exhaust rod 2, cooperate the sealing-in seal wire 3 of coefficient of expansion coupling, the electricity-saving lamp of manufacturing is not leaded, does not have environmental pollution.
When making stem stem, it comprises following technology:
One, crown glass pipe heating back and enlarging are become oviduct;
Two, after another crown glass pipe heating that bore is less,, make air exhaust rod to the tube wall draw down corresponding with the loudspeaker position;
Three, with crown glass sealing-in seal wire and nickel wire butt welding;
Four, aforementioned three parts are heated be packaged into stem stem.
