Abstract
The utility model relates to a tungsten lamp which belongs to the lighting lamp technology field. The tungsten lamp includes a lamp housing, a lamp head which is connected with the lamp housing, and a tungsten filament which is arranged in the lamp housing. The tungsten filament is connected with two electrodes in the lamp head via leads. The leads are fixed on a lead support in the lamp housing. The lead frame support is provided with tungsten filament holding frame. The tungsten filament holding frame is evenly provided with multiple fixing filaments, and each fixing filament is wound with a loop which sleeves the tungsten filament. The tail of each fixing filament extends to the outside of the tungsten filament holding frame. The loop is formed by bending one end of the fixing filament by more than 270 degrees. Because the tungsten filament holding frame in the tungsten lamp is provided with multiple fixing filaments, and each fixing filament is wound with the loop which can sleeve the tungsten filament, and the tail of the fixing filament extends to the outside of the tungsten filament holding frame, the tungsten filament can enter into the loops in order, and the danger that the tungsten filament is disconnected with the fixing filaments can not happen.
Description
Technical field
The utility model belongs to field of illumination lamp technology, is specifically related to a kind of structure of tungsten lamp.
Background technology
The filament of the tungsten lamp of prior art usually uses spiral helicine tungsten filament, and filament is longer like this, the diameter of filament can do more greatly prolonging its useful life, but owing to spiral helicine filament has bigger elasticity, so need many places to fix between the filament two ends.Prior art is through being provided with the tungsten filament carriage on the conductor wire support; A plurality of anchoring filaments are set on the tungsten filament carriage to be supported tungsten filament; In actual production process; Generally about 180 degree of anchoring filament end bent are formed a crotch, then tungsten filament is hung over the crotch place of anchoring filament, the crotch of manual afterwards bending anchoring filament end makes it further clamp tungsten filament.But manual like this operation is difficult to guarantee that anchoring filament crotch place tungsten filament does not break away from; Sell at bulb that tungsten filament breaks away from anchoring filament because shake takes place easily in the transportation, possibly cause tungsten filament directly to contact glass lamp housing and cause lamp housing to be heated inequality and break even explode.
Summary of the invention
The purpose of the utility model is: the deficiency to the anchoring filament that is used to support tungsten filament in the prior art tungsten lamp, a kind of tungsten lamp rational in infrastructure is provided, and make the use of tungsten lamp safer.
For realizing the purpose of the utility model, adopt following technical scheme to be achieved: a kind of tungsten lamp, include lamp housing, the lamp holder that is connected with lamp housing and be arranged at the tungsten filament in the lamp housing, described tungsten filament passes through conductor wire and is connected with two electrodes of lamp holder; Described conductor wire is fixed on the conductor wire support in the lamp housing, and described conductor wire support is provided with the tungsten filament carriage, evenly is provided with a plurality of anchoring filaments on the described tungsten filament carriage, is wound with a lasso that entangles tungsten filament on described each anchoring filament; And the anchoring filament end of described anchoring filament extends towards tungsten filament carriage lateral direction.
As preferred version: described lasso is formed by terminal crooked 270 degree that surpass of anchoring filament,
As preferred version: described lamp housing inside is provided with reflector layer near the part of lamp holder.
Compared with prior art; The beneficial effect of the utility model is: owing on the tungsten filament carriage in tungsten lamp a plurality of anchoring filaments are set; And be wound with a lasso that entangles tungsten filament on described each anchoring filament, and the anchoring filament end is towards the extension of tungsten filament carriage lateral direction, like this; Tungsten filament can not break away from anchoring filament because of tungsten filament and cause danger easily successively around in each lasso.In addition, the lasso of anchoring filament part can be used automated machine that anchoring filament is carried out bending process and form, and can reduce cost of labor well.

1, conductor wire support; 2, tungsten filament carriage; 3, anchoring filament; 31, anchoring filament is terminal; 32, lasso; 4, conductor wire; 5, tungsten filament; 6, lamp housing; 7, reflector layer; 8, lamp holder.
Embodiment
According to accompanying drawing the embodiment of the utility model is done a detailed explanation below.
According to Fig. 1, Fig. 2 and shown in Figure 3, the described a kind of tungsten lamp of present embodiment includes lamp housing 6, the lamp holder 8 that is connected with lamp housing 6 and be arranged at the tungsten filament 5 in the lamp housing 6, and described tungsten filament 5 is connected with two electrodes of lamp holder 8 through conductor wire 4; Described conductor wire 4 is fixed on the conductor wire support 1 in the lamp housing 6; Described conductor wire support 1 is provided with tungsten filament carriage 2; Evenly be provided with a plurality of anchoring filaments 3 on the described tungsten filament carriage 2, be wound with a lasso 32 that entangles tungsten filament 5 on described each anchoring filament 3; And the anchoring filament of described anchoring filament 3 terminal 31 extends towards tungsten filament carriage 2 lateral direction.
Described lasso 32 is formed by anchoring filament 3 terminal crooked 270 degree that surpass; In addition, described lasso 32 can make nonocclusive, and described tungsten filament 5 can pass each lasso 32 easily; As long as tungsten filament 5 is not by excessive stretching, tungsten filament 5 is can not break away from anchoring filament 3 easily.
Described lamp housing 6 inside are provided with reflector layer 7 near the part of lamp holder 8.The light that tungsten filament 5 sent when reflector layer 7 can make tungsten lamp work penetrates towards fixed-direction, comprising also comprising infrared emanation, helps reducing the temperature of lamp housing 6 like this, prolongs the useful life of tungsten lamp integral body.
The upper and lower end of each parts described in the literary composition is to describe with shown in the accompanying drawing.
Described conductor wire 4 ends are bent into crotch, only need use pliers further to clamp crotch when tungsten filament 5 is installed and make it to clamp tungsten filament 5 and get final product.
Described anchoring filament 3 also leaves described anchoring filament end 31 after bending out lasso 32, and terminal 31 length of this anchoring filament are about 7mm.When tungsten filament 5 is passed each lasso 32,, also can recover the state of lasso 32 easily like this even error causes lasso 32 distortion.
