Description
Technical field
The utility model relates to electrode for discharge lamp fields, more particularly, to a kind of high-power high voltage gas-discharge lamp electrode bullet
Spring.
Background technique
The part of conventional gas discharge lamp most critical is exactly electric arc tube, and the part of electric arc tube most critical is exactly electrode.Electrode
Generally it is made of plug, spring.
The current density of high-voltage gas discharging light is high, and charged particle is stronger to the bombardment of electrode, and the operating temperature of electrode is very
Height, the effect of spring are exactly to distribute heat extra on plug, maintain equalized temperature.
Thus, a good electrode, the design of spring are also pith.The structure of general electrode spring has monofilament list
Layer coiling, monofilament double-layer coiling, the coiling of after-combustion silk single layer, after-combustion silk bilayer four kinds of structures of coiling.But with high-power electrode
Application range expands, and trendy electrode is constantly released, and four kinds of traditional spring structures have been unable to meet new design requirement.
Chinese patent CN203250718U discloses a kind of electrode for high-voltage gas discharging light, by plug and is connected to
Spring composition on plug, for plug from being front to back extension head part, fixed spring part and welding portion, spring includes successively connecting
The spring connect turns over head, spring is dredged around internal layer, spring neck and spring is arranged in turns over head and spring and dredge spring on the outside of internal layer
Outer layer composition.The structure of the electrode of the patent disclosure is exactly the structure of monofilament double-layer coiling, can not the high heat of bearing load
It flows through, therefore use scope is restricted.
Utility model content
The purpose of this utility model is exactly to provide a kind of high-power height to overcome the problems of the above-mentioned prior art
Pressure gas discharge lamp electrode spring.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of high-power high voltage gas-discharge lamp electrode spring, by internal layer spring and the outer layer bullet being set in outside internal layer spring
Spring composition constitutes and is arranged with little spring on the spring ring of outer layer spring.
The little spring is wound on spring ring along the radial direction of the spring ring of outer layer spring.It can be in outer layer spring
It is all arranged with little spring on spring ring, or is partially arranged little spring on the spring ring of outer layer spring.
The diameter of the spring ring of the little spring is the tungsten wire or thoriatde-tungsten wire of 0.1-0.5mm.
The diameter of the spring ring of the outer layer spring is the tungsten wire or thoriatde-tungsten wire of 0.5-1.5mm.
The diameter of the spring ring of the internal layer spring is the tungsten wire or thoriatde-tungsten wire of 0.5-1.5mm.
The axial length of the outer layer spring is equal with the axial length of internal layer spring, might be less that the axis of internal layer spring
To length.
Plug extension head end face and arc contacts when electrode works, ion bombardment and gas conductance impose on its heat at this time
Amount can soon be transmitted to electrode rear portion by plug, and heat extra on electrode is radiate by spring.In this way, emission layer
Temperature would not be excessively high, and emitting material would not consume too quickly, and electrode is made to maintain correct operating temperature.
So spring needs enough surface areas to distribute heat and high-mechanic and carry out flowing through for load high heat.This
The spring of scheme is exactly the improved structure for having both both functions, by outer layer spring further around little spring processed, further
The surface area for increasing spring is conducive to heat dissipation when electrode work, improves the light decay of electric arc tube.
Compared with prior art, the utility model has the advantage that
1, strong flexibility: by adjusting processing dimension, it may be designed to different specifications.
2, highly reliable: by the use of thick tungsten filamen+little spring part, to improve the performance parameter of lamp, also extend lamp
Service life.
3, strong applicability: it is suitable for powerful high-voltage gas discharging light.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial structural diagram of outer layer spring.
In figure, 1- outer layer spring, 2- little spring, 3- internal layer spring.
Specific embodiment
The utility model is described in detail combined with specific embodiments below.Following embodiment will be helpful to this field
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These are all within the protection scope of the present invention.
Embodiment 1
A kind of high-power high voltage gas-discharge lamp electrode spring, structure is as shown in Figure 1, by internal layer spring 3 and be arranged
Outer layer spring 1 outside internal layer spring 3 forms.Wherein, the diameter of the spring ring of internal layer spring 3 is 0.5mm, by pure tungsten filament winding system
It obtains.The diameter of the spring ring of outer layer spring 1 is also 0.5mm, is made by pure tungsten filament winding.In the spring ring of outer layer spring 1
Radial direction is wound with little spring 2, as shown in Fig. 2, this kind of little spring is obtained by the tungsten wire coiling that diameter is 0.1mm.It is logical in this way
It crosses on outer layer spring 1 further around little spring 2 processed, further increases the surface area of spring, facilitate heat dissipation.In the present embodiment, outer layer
The axial length of spring 1 is less than the axial length of internal layer spring 3, and such outer layer spring 1 is set in the outer of portion inner layer spring 3
