Abstract
The utility model discloses a ceramic electric arc lamp tube which is used for arc discharge. The ceramic electric arc lamp tube is mainly formed by sintering two lamp wicks in a butting manner, wherein each lamp wick comprises a connecting part and a tube part, a hollow concave part is formed in the center of the connecting part, a sintering part is formed on the surface of the periphery of the front end of the connecting part, the tube part is arranged at the rear end of the connecting part, a hollow pipeline running through the tube part is formed inside the tube part, and the hollow pipeline is communicated with a hollow concave part of the connecting part. Thus a containing chamber is formed through the two hollow concave parts after the two lamp wicks are sintered, arc electrodes can be arranged at two ends of the containing chamber, the electrodes are sealed and welded through the two hollow pipelines, and the containing chamber is vacuumized, so that the aim of improving the heat-resistant effect of the ceramic electric arc lamp tube is achieved so as to improve the lighting efficiency of the ceramic electric arc lamp tube.
Description
Technical field
The utility model relates to a kind of ceramic arc fluorescent tube that is used for arc discharge.
Background technology
Arc discharge lamp normally is applied in the place of high illuminance; Most arc discharge mainly is in set inside one ceramic lamp tube to be arranged; And the filament of using as arc discharge is arranged, and after ceramic lamp tube is evacuated, insert special discharge element or alloy in the ceramic lamp tube set inside.
After arc discharge lamp energising, can power supply be conducted to filament, make two ends excitatory after, and then reach luminous effect.
Yet, when arc discharge lamp when luminous, can produce quite high temperature; General glass ceramics fluorescent tube has goodish temperature capacity; But because the temperature that arc discharge lamp is produced when luminous is too high, cause burning of glass lamp easily, cause the general Glass lamp life-span not long.
Certainly, in order to improve the problems referred to above, the present modal practice is exactly in the manufacture process of ceramic lamp tube, and metal material is added in the ceramic material, uses the radiating effect that promotes ceramic lamp tube.But, in ceramic material, add metal material, though can promote the radiating effect of ceramic lamp tube, its effect is limited, life-span that still can't efficient prolongation ceramic lamp tube.
The whence this, the utility model designer is in order to improve above-mentioned variety of problems, through the experience of accumulation for many years, develops the ceramic arc fluorescent tube of the high temperature resistant and printing opacity of the utility model finally.
The utility model content
The purpose of the utility model is to provide a kind of ceramic arc fluorescent tube with heat-resisting effect.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of ceramic arc fluorescent tube mainly is to be formed with the docking mode sintering by two wicks, and each wick includes an a junction and a pipe portion, and these connecting portion central authorities are a hollow recess, are formed with sintering portion on the front periphery surface; This pipe portion is located at the rear end of this connecting portion, and inside has one and runs through the hollow pipeline of this pipe portion, and communicates with the hollow recess of this connecting portion.
Said wick is made by ceramic material.
The sintering portion of said wick includes the protuberance of at least one front periphery rat and the depressed part of at least one front periphery surface depression.
The protuberance and the depressed part of said wick are oppositely arranged.
Said two wicks are earlier with after the welding of low temperature laser, again with high temperature sintering together.
Said two wicks directly weld together with high power laser.
After adopting said structure, two wicks of the utility model ceramic arc fluorescent tube form a room through two hollow recess after connecting, and make it be able in room filament is set, and through two hollow pipelines room are vacuumized, and then reach the purpose that promotes radiating effect.

Embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
The utility model refers to a kind of ceramic arc fluorescent tube with heat-resisting effect especially about a kind of ceramic arc fluorescent tube.Wherein the indication pottery is a composite material of containing refractory oxide, nitride, carbide and each material mixing thereof.Below enumerate a preferred embodiment now with explanation the utility model, so have the knack of this art and know that all this is merely one for example, and be not in order to limit creation itself.The detailed description of relevant this preferred embodiment is following.
See also Fig. 1 and Fig. 2, perspective exploded view of the utility model and combination generalized section.As shown in the figure, the utility model ceramic arc fluorescent tube 10 mainly is to be formed with the docking mode sintering by two wicks 20.
Each wick 20 includes an a junction 21 and a pipe portion 22, and its connecting portion 21 central authorities are a hollow recess 23, is formed with sintering portion 25 on the front periphery surface 24; Pipe portion 22 is located at the rear end of connecting portion 21, and inside has the hollow pipeline 26 of consistent poling portion 22, and communicates with the hollow recess 23 of connecting portion 21.
In the present embodiment, two wicks 20 are to utilize ceramic material with high pressure or low pressure injection molding, or accomplish with injection forming.
Two wicks 20 are when sintering, and main elder generation docks two wicks each other, and with after low temperature (below about 600 degree C) the laser welding, form with high temperature sintering, or directly weld two wicks 20 with high power laser.
Please consult simultaneously shown in Figure 3, the sketch map of the utility model wick.As shown in the figure; The utility model wick 20; Its sintering portion 25 includes the depressed part 28 of the protruding lug boss 27 at least one front periphery surface 24 than connecting portion 21 and at least one front periphery surface 24 depressions than connecting portion 21; When two wicks 20 connected with butt joint high temperature sintering mode, the lug boss 27 and the depressed part 28 of two wicks 20 were provided with each other, use the connection effect that can provide preferable.
Please consult Fig. 1 simultaneously to shown in Figure 3; When two wicks connect, main earlier with low temperature (below about 600 degree C) laser welding, or directly weld with high power laser; Again to be higher than the temperature of 1600 degree C; The high temperature sintering mode forms, and then forms a ceramic arc fluorescent tube 10, and makes ceramic arc fluorescent tube inside be formed with a room.
So; When the utility model ceramic arc fluorescent tube 10 is applied to arc discharge lamp; Can filament be fixed in the room inside of ceramic arc fluorescent tube 10, and ceramic arc fluorescent tube inside is vacuumized, use through this inside heat-resisting by the made wick 20 of ceramic material; And then reach the heat-resisting effect that promotes ceramic arc fluorescent tube 10, be purpose to promote its luminous efficiency.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
