Abstract
The utility model relates to a bullet shaped electrode applied to a point light source. The electrode is composed of a core rod and a spring. The spring is stuck at the front end of the core rod. The front end of the spring is in the shape similar to a bullet structure, wherein the shape is formed by laser melting. Compared with the prior art, when the bullet shaped electrode applied to the point light source is in use, the phenomenon of tungsten metal accumulation is highly unlikely to happen. The electrode distance is stable, and the lamp performance basically remains the same. In addition, when the bullet shaped electrode applied to the point light source is processed, the process is stable, the product consistency is good, the device universality is strong, and electrodes of different sizes can be processed.
Description
Technical field
The utility model relates to a kind of point-source of light and uses electrode, especially relates to a kind of point-source of light and uses the bullet shaped electrode.
Background technology
Very-high performance mercury lamp electrode generally is made up of plug, spring, and material is a high purity tungsten, is operated among the above air pressure of 200bar, and present electrode end surface is about sphere half, by the electric arc melting moulding.Pole span between the pair of electrodes is about 1mm.After electrode was started working, under the effect of alternating electric field, halogen tungsten circulation and superelevation air pressure, the tungsten metal was constantly piled up to electrode end surface; The electrode end surface shape progressively by hemisphere to the bullet shaped transition; Pole span constantly changes/dwindles, and pipe is also pressed and changed, and is final; The performance of lamp also changes thereupon, and this is that people are undesirable.
The utility model content
The purpose of the utility model is exactly a kind of stable, high conformity easy to process is provided in order to overcome the defective that above-mentioned prior art exists, has basically no the point-source of light that the phenomenon of tungsten metal accumulation takes place and use the bullet shaped electrode.
The purpose of the utility model can realize through following technical scheme:
A kind of point-source of light is used the bullet shaped electrode, is made up of plug and spring, and described Spring Card is located at the front end of plug, the shape that be similar to bullet structure of the front end of spring for forming through lf.
The length of described plug is 6-16mm, and diameter is 0.2-0.8mm.
The diameter of described spring is 0.4-2.0mm.
The drift angle of the front end of described spring is 40-60 °.
Further, the plug of use and spring all adopt the high purity tungsten making to obtain.
Compared with prior art, the utlity model has following advantage:
(1) the bullet shaped electrode in use has basically no the phenomenon generation of tungsten metal accumulation, and pole span is stable, and the performance of lamp is consistent basically.
(2) the utility model is adding the process stabilizing in man-hour, good product consistency, and equipment interoperability is strong, can process the electrode of different size.
Description of drawings
Fig. 1 is the structural representation of the utility model.
