It is stretched out out of blister after both passing through interconnecting piece, filled with protective gas in the blister, is coated with zirconium on the top of two seal wires
Aluminium powder layer, the length of the zirconium aluminium powder layer and the length for being equal to or more than tungsten filament helix part.
After adopting the above structure, compared with prior art, the utility model has the advantage that
Tungsten wire is fixed by two seal wires in the utility model, the shape of tungsten wire is in zigzag, and the middle part of tungsten wire is in
Helical form and along the vertical direction of blister be arranged, the tungsten wire that middle part is twist arranged increase tungsten wire it is effective shine grow
Degree, fully ensures that the illumination effect of light bulb, and again on the basis of this, is coated with zirconium aluminium powder layer on the top of two seal wires, this
For sample when tungsten wire is when luminous, zirconium aluminium powder layer can eliminate the miscellaneous gas that tungsten wire comes out as getter, to play extension tungsten
Silk service life and the problem of alleviate light bulb melanism, such design but also in blister the pressure of protective gas do not need it is very big,
The production difficulty of light bulb just is reduced, is suitable for producing in enormous quantities.
As an improvement, all having the segmental arc to concave in the middle part of two seal wires, and logical in the segmental arc part of two seal wires
Plastic cement connection is crossed, in this way, two seal wires can be connected, the stability of seal wire entirety is improved, so that tungsten wire is fixed
It is more firm.
As an improvement, the upper end level of two seal wires is above the height of tungsten wire, guarantee the zirconium aluminium coated by seal wire top
Bisque is enough, to guarantee reaction effect.
As an improvement, the inside of interconnecting piece offers the aeration aperture for inflating into blister, in this way, by aeration aperture to
Protective gas is filled in blister.
As an improvement, the shape of interconnecting piece be it is flat, be equipped on the tow sides of interconnecting piece for connecting with lamp holder
The card slot and dowel connect is at least 2 in the quantity of the upper card slot of any one side of interconnecting piece, and is distributed in dowel
The left and right sides, in this way, have the mounting groove that matches with interconnecting piece on lamp holder, to pass through card slot on interconnecting piece and connection
Light bulb and lamp holder are attached by muscle.
As an improvement, the shape of blister is spherical shape.
As an improvement, the shape of blister is ellipse.

Specific embodiment
The utility model is described in further detail below:
The utility model provides a kind of light bulb, including blister 1, and 1 lower end of blister has the interconnecting piece for connecting with lamp holder
2, the blister 1 is interior to be equipped with tungsten wire 3 and two seal wires 4, and the tungsten wire 3 is in Z-shaped, and 3 middle part of tungsten wire is in the shape of a spiral and along vertical
The upper and lower ends of direction setting, the tungsten wire 3 are connect with the top of two seal wires 4 respectively, and the lower end of the seal wire 4 both passes through company
It is stretched out out of blister 1 after socket part 2, filled with protective gas in the blister 1, is coated with zirconium aluminium powder on the top of two seal wires 4
Layer 5, the length of the zirconium aluminium powder layer 5 and the length for being equal to or more than 3 spiral part of tungsten wire.Tungsten wire 3 is led in the utility model
It crosses two seal wires 4 to be fixed, the shape of tungsten wire 3 is in zigzag, and the middle part of tungsten wire 3 is in the shape of a spiral and along the vertical side of blister 1
To setting, the tungsten wire 3 that middle part is twist arranged increases effective length of illumination of tungsten wire 3, fully ensures that the luminous effect of light bulb
Fruit, and again on the basis of this, is coated with zirconium aluminium powder layer 5 on the top of two seal wires 4, in this way when tungsten wire 3 is when luminous, zirconium aluminium
Bisque 5 can eliminate the miscellaneous gas that tungsten wire 3 comes out as getter, thus play extend 3 service life of tungsten wire and alleviate light bulb it is black
