Abstract
An automobile halogen lamp comprises a lamp tube and a lamp filament arranged in the lamp tube. Two lead feet of the lamp filament stretch out from a burn-weld sealing part on the lower end of the lamp tube. The automobile halogen lamp is characterized in that the joint of the upper end of the burn-weld sealing part and the lamp filament is a smooth connecting plane. Lugs are arranged between the lead feet of the lamp filament on the connecting plane. Area of thrust surface of the joint of the upper end of the burn-weld sealing part of the lamp tube and the lamp filament can be changed through preparing a compacting die of the automobile halogen lamp. Grooves and lugs connected in a matching mode are respectively arranged on abutting joint ends of a left module and a right module. Protruding length of the lugs is shorter than groove depth of the grooves, and the lugs and the grooves form a closed notch in an abut joint mode, and thereby achieving the upper limit of improving crushing pressure intensity, preventing the lamp tube from bursting, and then prolonging service life of the automobile halogen lamp.
Description
Technical field
The present invention relates to automobile halogen lamp and make the field, relate in particular to a kind of automobile halogen lamp and compacting tool set thereof.
Background technology
Halogen is VII A family element (the IUPAC new regulation: 17 families) in the periodic table of chemical element.The profile of automobile halogen lamp is all generally a tiny quartz glass tube, compares with incandescent lamp, and its particularity just is that tungsten filament can " self-regeneration ".In fact, be filled with some halogens in the filament of this lamp and glass shell, as iodine and bromine.When the filament adstante febre, tungsten atom is evaporated to the glass tube walls direction and moves.At them during near glass tube, the tungsten steam by " cooling " to about 800 ℃ and and halogen atom combine, formation tungsten halide (tungsten iodide, tungsten bromide).Tungsten halide is fallen again on the filament that is corroded to the glass tube central mobile.Because tungsten halide is very unstable, will resolve into halogen vapour and tungsten after heated, tungsten under deposition on filament, has made up the part that is evaporated again like this.So circulation, will extend much the useful life of filament.So the less that the filament of Halogen lamp LED just can be done, lamp body are also very small and exquisite.
In the situation that desirable gas flow constant (quality or molal quantity) PV/T=nR=C, wherein P is pressure, and V is volume, and T is thermodynamic temperature (Kelvin), and n is molal quantity, and R is ideal gas constant, and C represents constant (constant).The tungsten rear circulation of being heated in Halogen lamp LED, tungsten atom is evaporated to the glass tube walls direction and moves, and can form pore on tube wall, affects brightness and the life-span of bulb.In the situation that the volume V of auto lamp is constant, the ratio of the pressure that only changes P and temperature T is accomplished both best joints as far as possible, and just can be provided the useful life of bulb.
For solving this technical problem, at first by rush gases at high pressure in the bulb of same volume, increase pressure, reduce dispersing of tungsten molecule, air pressure is higher, and the tungsten molecule more is difficult for dispersing, and air pressure is 12 atmospheric pressure at normal temperatures; And iodine, tungsten lamp can reach 50 atmospheric pressure, but the excessive tube wall that can make again of pressure blasts, and have much room for improvement.
Then consider to change temperature T, damage the impossible random change in border but temperature relates to making of bulb, be difficult to improve again.
Therefore all there is short problem in useful life in existing automobile halogen lamp on the market, haves much room for improvement.
Summary of the invention
The present invention is directed to above-mentioned technical problem, a kind of long service life is provided, make simple automobile halogen lamp and compacting tool set thereof.
The key problem in technology of this is, in the situation that can fine control temperature and pressure best combination ratio, innovation has been considered in temperature, air pressure and the mutually moderate indeclinable situation of overall lamp pipe volume V, carry out the change that the fluorescent tube pressurized bears the force area, also namely utilize the abundant adjustment of fluorescent tube mould, moment is shaped in the situation that freeze in the fluorescent tube lower end, and the area that air pressure can be born pressure rationally changes, and changes over a mild stress surface by a crosspoint.
Specifically be achieved in that a kind of automobile halogen lamp, comprise fluorescent tube and be arranged at the interior filament of fluorescent tube, two pins of filament sealing that freezes from the fluorescent tube lower end stretches out, it is characterized in that the freezing junction of sealing upper end and filament is mild joint face, as preferably, between filament leg, projection is arranged on described joint face.
A kind of automobile halogen lamp compacting tool set, about comprising, the module of two docking, is characterized in that module butt end, described left and right is respectively arranged with the groove that connects and a projection, and described projection projection length is shorter than the groove groove depth, and docking forms a closed notch.
As preferably, the width of described closed notch is 2.8 ~ 3.2mm.The freeze lifting surface area of junction of sealing upper end and filament of the fluorescent tube that can effectively increase the moulding of freezing by the notch that this kind width preferably is set, increase the upper limit of bearing pressure of fluorescent tube, can explosion in the situation that pour larger pressure fluorescent tube in the fluorescent tube, effectively extend the useful life of Halogen lamp LED.
As preferably, groove and the projection of described left and right module are arranged at module centers.
As a further improvement on the present invention, module upper surface center, described left and right all has a strip groove that mutually connects, but be provided with the strip slide block that an inlay card wherein horizontally slips in each groove of module of described left and right, all offer on slide block be used to the through hole that makes slide block and groove bolted.Can form the up and down twenty percent compacting of freezing by this kind setting, effectively improve the sealing of fluorescent tube compacting, and can spirit regulate the width of suppressing, control the thickness of the sealing that freezes that freezes out by the distance of regulating two slide block interfaces.
As preferably, the butt end of described slide block offers corresponding breach, and described breach is semicircle, is arranged at center, described butt end.Be arranged on by this kind and import in breach after fluorescent tube being freezed melt, make the junction of freeze sealing upper end and filament form projection upwards, improve bonding strength and the lifting surface area of described junction, thereby make fluorescent tube can bear higher pressure and not explosion.
As preferably, described two slide block bolts are fixed on separately strip groove, and two slide block interfaces are at a distance of 1.8 ~ 2.4mm.Preferred this kind distance can increase the compression strength of the junction of freeze sealing upper end and filament, the useful life of effective prolonging lamp tube greatly by thousands of evidences.
As preferably, described groove and projection are trapezium structure.
Beneficial effect of the present invention: the present invention changes the fluorescent tube lifting surface area of junction of sealing upper end and filament that freezes by the preparation compacting tool set, thereby reaches the upper limit that pressure is poured in raising, prevents the fluorescent tube explosion, thereby has improved the useful life of automobile halogen lamp.
