The production method is: firstly, the surfaces of the electrode (2) and the metal conduit (4) are to be passivated, secondly, the ceramic tube (1) and the electrode (2) are assembled together, the metal conduit (4) and the ceramic tube (1) are assembled together, thirdly, heat is applied to seam the two ends of the ceramic tube (1) with the electrode (2) as well as the exterior surface of the metal conduit (4) with the ceramic tube (1); inert gas, pills and mercury are filled through the metal conduit, finally, the outer end of the metal conduit (4) is to be sealed by laser, thereby realizing a simple structure and a simpler manufacturing method.
Description
Technical field
The present invention relates to a kind of metal halide lamp that has ceramic discharge tube, particularly a kind of power at 5W to small power porcelain metal halogen lamp between the 15W and manufacture method thereof.
Background technology
In recent years, adopt the metal halide lamp of semi-transparent polycrystal aluminium oxide ceramic material to obtain fast development, market prospects are wide.The typical process for sealing of this ceramic metal helide lamp discharge tube is: draw two elongated earthenwares on the both sides of electric arc cavity, the electrode outlet line that the niobium silk is made by scolder at high temperature with the airtight sealing-in of earthenware.
Above technology mainly is in order to reduce the influence of thermal expansion to sealing-in.But particularly below the 15W, because its power is little, the temperature of earthenware is very low for low power ceramic metal helide lamp, and thermal expansion is very little, little to the influence of sealing-in.Do not need both sides to draw very long earthenware, solve the too high problem of temperature.And the used electrode of small power porcelain metal halogen lamp is very little, the thermal expansion of itself is also very little, prior art still adopt electrode outlet line that the niobium silk makes by scolder at high temperature with the airtight sealing-in of earthenware, complex process is difficult for sealing, because niobium silk tool fragility, easily broken in welding process, thereby rate of finished products is low, and production efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of structure more simply, the small power porcelain metal halogen lamp of easier sealing.Another technical problem that will solve of the present invention is that a kind of method of making this small power porcelain metal halogen lamp also will be provided in addition, and this method technology is simple, rate of finished products is high, production efficiency is high.
For solving the problems of the technologies described above, a kind of small power porcelain metal halogen lamp of the present invention comprises earthenware, two electrodes, and the two ends of described earthenware and described two electrodes directly are tightly connected, and a metal catheter is set on the earthenware, the sealing of metal catheter one end, the other end is communicated with earthenware.
Preferably, metal catheter adopts Mo.
In order to make above-mentioned small power porcelain metal halogen lamp, manufacture method of the present invention comprises following several steps: at first the surface passivation of two electrodes and metal catheter is handled, then two electrodes, metal catheter are fitted together with earthenware respectively, and then realize two ends and two electrodes, the outer surface of metal catheter and being tightly connected of earthenware of earthenware by heating, in the earthenware cavity, fill inert gas, pill and mercury by metal catheter then, use the outer end of laser package metallic conduction pipe at last.
Preferably, being tightly connected of the outer surface of described earthenware and electrode, metal catheter and earthenware undertaken by the method for direct sintering.
After adopting such structure,, simplify the structure, simplified manufacturing process, easier sealing because electrode directly is connected with the two ends of earthenware.
After adopting above-mentioned manufacture method, because electrode directly is connected with the two ends of earthenware, earthenware two ends extraction tube can be provided with shorter, and electrode needn't connect niobium silk lead-out wire, has avoided the defective of the easy brittle failure of niobium silk; The sealing of earthenware and electrode, metal catheter and earthenware adopts the method for heating to seal simultaneously; So manufacture method manufacture process of the present invention is simplified, can realize sealing in batches, rate of finished products height, production efficiency height.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of low power ceramic metal helide lamp of the present invention.
Embodiment
Fig. 1 shows a kind of embodiment of a kind of small power porcelain metal halogen lamp of the present invention, comprise earthenware 1, two electrodes 2, the two ends of earthenware 1 directly are tightly connected with two electrodes 2, on earthenware 1, also connect a metal catheter 4, one end of metal catheter 4 is connected with earthenware 1, its endoporus can be used as a steam vent 3 in manufacture process, and fills inert gas in earthenware 1, add fillers such as pill and mercury by steam vent 3.But in the end, need outer end sealing, thereby make steam vent 3 sealings metal catheter 4.
The material of metal catheter 4 is the corrosion resistant Mo of many employings in actual selection.
For low power ceramic metal helide lamp particularly below the 15W, because its power is little, the temperature of earthenware 1 is very low, thermal expansion is very little, and is little to the influence of sealing-in, so, can be with the two ends of electrode 2 direct sealing-ins at earthenware, need not insert niobium silk lead-out wire, more need not draw very long earthenware, solve the too high problem of temperature at earthenware 1 two ends at the two ends of electrode 2; And the used electrode of small power porcelain metal halogen lamp is very little, and the thermal expansion of itself is also very little, therefore, can directly electrode 2 directly be sealed in the earthenware 1, so earthenware 1 two ends extraction tube can be provided with shorter.The relative prior art of this structure is more simple, easier sealing, and can realize sealing in batches.
The manufacture method of above-mentioned small power porcelain metal halogen lamp is, at first the surface passivation of electrode 2 and metal catheter 4 is handled, then earthenware 1 and electrode 2 are fitted together, metal catheter 4 fits together with earthenware 1, and then realize the two ends and the electrode 2 of earthenware 1 by the method for direct sintering, the sealing of the outer surface of metal catheter 4 and earthenware 1, electrode 2 and metal catheter 4 through transpassivation, can make earthenware 1 and electrode 2, the outer surface of metal catheter 4 and earthenware 1 complete airtight sealing, these two sealings are to be undertaken by the method for direct sintering simultaneously, and small power porcelain metal halogen lamp in batches can be sealed simultaneously, improved production efficiency, fill inert gas by metal catheter 4 inner vents 3 then, add fillers such as pill and mercury, use the outer end of laser package metallic conduction pipe 4 at last.
As shown in Figure 1, a kind of low power ceramic metal helide lamp, adopt directly and electrode 2 sealings at its earthenware 1 two ends, and a steam vent 3 is arranged near the electrode sealed end, is used for fillers such as in earthenware 1 cavity adding inert gas and required metal halide, mercury.With the laser sealed-off whole discharge tube is sealed fully then.The 5W ceramic gold-halogen lamp performance parameter that adopts this method to make is as follows: light efficiency: 80Lm/w; Colour temperature discreteness: 150; Life-span: more than 8000 hours.
The ceramic metal helide lamp that all design on the method is all in protection range of the present invention.
