Abstract
A novel electrode for a ceramic metal halogen lamp comprises a tungsten rod, a tungsten spiral, a molybdenum spiral, a niobium rod, and a tungsten filament, the tungsten rod is winded with the tungsten spiral and the molybdenum spiral which is winded with the tungsten filament; one end of the tungsten filament is fixed between a first loop and a second loop of one end of the molybdenum spiral close to the niobium rod while the other end of the tungsten filament is fixed on the molybdenum spiral after clockwise revolving around the molybdenum spiral. The novel electrode for the ceramic metal halogen lamp has the characteristics of long life, high photosynthetic efficiency, high color rendering and the like, and is more stable in performance and easy to produce.
Description
Technical field
The utility model relates to the Metal halogen lamp electrode, is specially a kind of new ceramics Metal halogen lamp electrode.
Background technology
In today that energy day is becoming tight, high light efficiency, high-color rendering, long-life product more and more is subject to pursuing of market.Light source product is after the development of having experienced first generation tungsten halogen lamp and second generation low pressure discharge fluorescent lamp and third generation quartz metal halide lamp.More outstanding light source product----ceramic gold-halogen lamp has appearred.
Ceramic gold-halogen lamp is based on and develops on the basis of quartz metal halide lamp and high-pressure sodium lamp, and it has taken into account both advantages.Have long-life and high light efficiency, the advantage of high colour developing, ceramic lamp is at the requirement of raw material and processing links unusual height just like this, the place of ceramic gold-halogen lamp key is the consistency that how to guarantee the sealing-in effect, for the consistency that guarantees the sealing-in effect has designed a kind of novel electrode targetedly, on performance, should be able to well the meeting the demands of this electrode.
Summary of the invention
The technical problem that the utility model solves is to provide
OnePlant new ceramics Metal halogen lamp electrode, to solve the problem that proposes in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of new ceramics Metal halogen lamp electrode comprises tungsten bar, tungsten spiral, molybdenum spiral, niobium bar, tungsten spiral, is wound with respectively tungsten spiral and molybdenum spiral above the described tungsten bar, is wound with tungsten filament above the molybdenum spiral.
One end of described tungsten filament is fixed between first and second circles of molybdenum spiral near niobium bar one end, and the other end is fixed on the molybdenum spiral after the molybdenum spiral clockwise rotates.
Described tungsten filament diameter is 0.04-0.05mm, and length is 2-3mm.
The lower thermal conductivity that the used very thin tungsten bar electrode of the utility model and elongated molybdenum spiral have guaranteed electrode system, also be one of important measures that guarantee niobium rod seal position low temperature, outer molybdenum spiral and the tungsten filament of tungsten bar almost filled up ceramic bulb shell space capillaceous, so not only effectively controlled the cold junction space but also guaranteed the concentricity of electrode, the Photochromic Properties of whole bulb had been had a good guarantee; This kind electrode assemblie most critical part is that the increase of on the one hand tungsten filament can effectively cut off pill the unfailing performance of the such sealing-in of corrosion of niobium bar is just strengthened greatly in addition, can not cause the phenomenon that is corroded and leaks air because of the niobium bar.The increase of tungsten filament can be with the Position Control of glass solder near tungsten filament on the other hand, effectively controlled the space of cold junction, photochromic consistency has been played good guarantee effect, after tungsten filament is lived the Position Control of glass solder simultaneously, go down to occur too much that glass solder is heated the phenomenon of ceramic capillary spalling in the bulb course of normal operation because of glass solder with regard to not occurring, therefore the variety of problems that appearance has well solved in process of production or the launch later stage occurs of this kind electrode assemblie will play huge effect to quality and the performance that improves ceramic lamp.
Compared with prior art, the beneficial effects of the utility model are: the utlity model has the long-life, and high light efficiency, the characteristics such as high-color rendering, performance is more stable, and is easy to produce.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make realization technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of new ceramics Metal halogen lamp electrode comprises tungsten bar 1, tungsten spiral 2, molybdenum spiral 3, niobium bar 4, tungsten spiral 5, and wherein modular construction all is that mode by laser welding is processed into; Be wound with respectively tungsten spiral 2 and molybdenum spiral 3 above the described tungsten bar 1, be wound with tungsten filament 5 above the molybdenum spiral 3.
One end of described tungsten filament 5 is fixed between first and second circles of molybdenum spiral 3 near niobium bar 4 one ends, and the other end is fixed on the molybdenum spiral 3 after molybdenum spiral 3 clockwise rotates.
Described tungsten filament 5 diameters are 0.04-0.05mm, and length is 2-3mm.
The utility model is made concrete steps: a kind of new ceramics Metal halogen lamp electrode; comprise tungsten bar 1; tungsten spiral 2; molybdenum spiral 3; niobium bar 4 and tungsten spiral 5; wherein modular construction all is that mode by laser welding is processed into; adopt laser welding to form together between two end faces that the tungsten bar 1 of previous section and tungsten spiral 2 are in contact with one another; the welding number of turns is that 4 circle length are 2.5mm; between the both ends of the surface that tungsten bar 1 and molybdenum spiral 3 are in contact with one another, also adopt laser welding to form together; the number of turns is that 18 length are 9mm; the 3rd part is that the end of tungsten bar 1 by laser welding and niobium bar 4 welded together; argon shield is all adopted in whole welding in the welding process, guarantee that the phenomenon of weld non-oxidation occurs.
At last the end on the molybdenum spiral 3 around on tungsten filament 5, diameter be 0.04mm length be 2mm tungsten filament 5 one ends by laser welding molybdenum spiral 3 first and second the circle between, around the gap the inside closely coiling of molybdenum spiral 3 between spiral, with laser an other end is welded on the molybdenum spiral 3 again.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
