Description
Technical field
The utility model relates to lighting electric light source, relates in particular to a kind of tungsten nickel electrode of photoflash lamp.
Background technology
The sparking electrode of known in the market photoflash lamp product is to adopt metal such as tungsten, vanadium, tantalum, zirconium, titanium, niobium, barium, nickel, molybdenum and alloy material thereof to make basically.
This type of sparking electrode adds electrode tip by electrode stem and forms, and can be divided into two types: one type is the mercury dispenser electrode tip at the top of electrode stem assembling tubulose; Another kind of type is tubulose or the spiral helicine electrode tip made from metal such as tungsten or tantalum, zirconium, titanium, niobium, nickel, molybdenum and alloy material thereof in the assembling of the top of electrode stem.This sparking electrode head of two types is guaranteeing all there is certain technology difficulty aspect axiality of discharging between two electrodes and the intensity of the keeping electrode.
Although made great efforts to have used nearly all rare metal of stable performance that under the condition of high temperature, can keep to make sparking electrode, with the life-span of support and prolonging lamp tube.But use in the process of photoflash lamp product in reality, people have found that often fluorescent tube blackout phenomenon, electrode tip obscission produce.This is because irregular electrode tip shape, very easily causes local point discharge and causes blackout, and the electrode tip distortion that also can cause that localized hyperthermia is serious comes off, and has influenced the normal use of product.
Summary of the invention
The purpose of this utility model is exactly the tungsten nickel electrode that a kind of collimation that improves product is provided in order to overcome the defective that above-mentioned prior art exists, increases the photoflash lamp of pole strength.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of tungsten nickel electrode of photoflash lamp is characterized in that, comprises tungsten bar, nickel bar or nickel manganese bar, and described tungsten bar and nickel bar or nickel manganese bar are welded into as a whole, constitutes the tungsten nickel electrode of photoflash lamp.
Described tungsten bar is after chamfering, surface grinding, blasting treatment, with nickel bar or the nickel manganese pole pair weldering formation electrode after alignment.
Described tungsten nickel electrode is a rod-shaped electrode.
Only be provided with a pad on the described electrode.
The size of described tungsten bar designs according to different lamp power with the roughness on surface.
The diameter range of described tungsten bar is Φ 0.3mm～Φ 2.0mm, and range of surface roughness is Ra0.5um～Ra1.3um.
The fusing point temperature difference of tungsten (3410 ℃), two kinds of materials of nickel (1452 ℃) is big, and described tungsten bar, nickel bar directly butt welding are assembled into sparking electrode.The waveform of bonding machine pulse power suitably is controlled in certain scope, makes the nickel local melting encase the tungsten bar fully, guarantee the fastness of welding and the consistency of node size shape.
For fluorescent tube integral body, electrode is a light emitting source, promptly is its cardiac component.In order to prolong the useful life of bulb, must guarantee the quality of sparking electrode, the utility model adopts the rod-shaped electrode of a kind of tungsten bar, the direct butt welding of nickel bar to substitute the sparking electrode that tradition is equipped with electrode tip, and its effect is fairly obvious.
Compared with prior art, the tungsten nickel electrode of the utility model photoflash lamp has only one to be positioned at the pad that discharge tube connects nickel or nickel manganese lead-in wire outward, and the tungsten bar part in enclosing discharge tube is without any the erection welding point, and product strength obviously improves; The tungsten bar is after chamfering, surface grinding, blasting treatment, be welded into as a whole with nickel bar after the alignment or nickel manganese bar, the shaft-like sparking electrode of forming pulse flashing light, obviously can improve the collimation of product, effectively overcome local point discharge phenomenon, prolonged the useful life of electrode, saved the metal material that electrode tip is made in the high thing of valency rare being used to, simplify production technology, reduced product cost.
