Abstract
An automobile halogen lamp and a compacting die thereof are provided. The 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 at 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 the 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 the automobile Halogen lamp LED and make the field, relate in particular to a kind of automobile Halogen lamp LED 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 LED generally all is a tiny quartz glass tube, compares with incandescent lamp, and its particularity just is that tungsten filament can " self-regeneration ".In fact, in the filament of this lamp and glass shell, be filled with some halogens, 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 ℃ also 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 the chance heat, tungsten under the filament deposition, has remedied the part that is evaporated again like this.So circulation, will prolong much the useful life of filament.So it is less relatively that the filament of Halogen lamp LED just can be done, lamp body is also very small and exquisite.
(quality or molal quantity) PV/T=nR=C under the constant situation of desirable gas flow, 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).Circulation after tungsten is heated in the Halogen lamp LED, tungsten atom is evaporated to the glass tube walls direction and moves, and can form pore at tube wall, influences brightness and the life-span of bulb.Under the constant situation of the volume V of auto lamp, 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 the body of calming the anger of in the bulb of same volume, leaping high, increase pressure, reduce dispersing of tungsten molecule, air pressure is more high, 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.
So all there is short problem in useful life in existing automobile Halogen lamp LED 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 LED and compacting tool set thereof.
This key problem in technology is, can not fine control temperature and the situation of pressure best combination ratio under, innovation has been considered under 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, under freezed the situation that moment is shaped in the fluorescent tube lower end, the area that air pressure can be born pressure rationally changed, and changes over a mild stress surface by a crosspoint.
Specifically be achieved in that a kind of automobile Halogen lamp LED, 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 the described joint face.
A kind of automobile Halogen lamp LED compacting tool set, the module of two butt joints about comprising is characterized in that module butt end, the described left and right sides is respectively arranged with the groove that connects and a projection, and described projection projection length is shorter than the groove groove depth, and butt joint forms a closed notch.
As preferably, the width of described closed notch is 2.8 ~ 3.2mm.The freeze lifting surface area of sealing upper end and the junction of 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, fluorescent tube can explosion under the situation that pours big pressure in fluorescent tube, effectively prolongs the useful life of Halogen lamp LED.
As preferably, groove and the projection of described left and right sides module are arranged at module centers.
As a further improvement on the present invention, module upper surface center, the described left and right sides all has a strip groove that connects mutually, but be provided with the strip slide block that an inlay card wherein horizontally slips in each groove of module of the described left and right sides, all offer on the slide block be used to the through hole that makes slide block and groove bolted.Can form up and down the 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 fluorescent tube to be freezed melt the back and import in the breach, 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 bolt are on strip groove separately, and two slide block interfaces are at a distance of 1.8 ~ 2.4mm.Preferred this kind distance can increase the compression strength of freeze sealing upper end and the junction of filament, the effectively useful life of 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 freeze lifting surface area of sealing upper end and the junction of filament of fluorescent tube by the preparation compacting tool set, improves the upper limit that pours pressure thereby reach, and prevents the fluorescent tube explosion, thereby has improved the useful life of automobile Halogen lamp LED.
