Definitions

  • the present invention relates to a manufacturing method for a discharge lamp designed for dielectrically impeded discharges.
  • Such lamps designed for dielectrically impeded discharges are known per se.
  • a discharge space of a discharge vessel is used to hold a discharge medium, often xenon (Xe).
  • Xe xenon
  • the electrode set can be provided inside or outside the discharge space. It is necessarily at least partially separated from the discharge medium by a dielectric layer, which may also be formed by a discharge vessel wall.
  • Flat radiators are known in which the discharge vessel has a bottom plate and a ceiling plate, which are connected by a running in the region of the outer edge of the plates frame, which may also be part of one of the two plates.
  • the present invention is not limited to the flat radiator design. However, it is known in this design supporting elements between provide the plates which serve to shorten the effective bending lengths and to mechanically stabilize the discharge vessel. This is important because of the backlighting of areal display devices, in some cases larger formats of the flat radiators and also because of the vacuum prevailing in the discharge medium.
  • the present invention is not limited to discharge lamps having such support members.
  • a sealing surface provided on the frame of the flat radiator can also be provided with a softening material such that this sealing surface produces a sealing connection when the corresponding parts are brought into contact with each other. As a result, the discharge space can be closed automatically during the filling step.
  • the filling step serves to dilute the residual atmosphere in the discharge space as much as possible and to fill it with the desired discharge medium.
  • the support elements have the function of initially holding the ceiling plate of the flat radiator above the frame, so that an opening for filling the discharge space is kept free between the underside of the ceiling panel and the top of the frame. Now, if the mentioned parts of the support elements sufficiently soften at a corresponding temperature, the ceiling plate is lowered by gravity, because these support member parts are flattened. By the bottom of the ceiling tile comes to rest against the sealing surface on the frame, a tight connection and thus the desired inclusion of the discharge medium in the discharge space and the closure thereof can be realized.
  • glass solder materials or comparable substances are used both for the sealing surface and for the softening support element parts.
  • the structure of the support elements, the typical temperatures and the favorable viscosities of the various parts of the support elements is made to the disclosure of the mentioned document.
  • the present invention is based on the problem of specifying a discharge method which is improved with regard to the filling step and for a discharge lamp designed for dielectrically impeded discharges.
  • the invention is directed to a manufacturing method for such a discharge lamp in which one of at least two parts of the discharge vessel is held up by a supporting element during filling step preceding a closing of the discharge space, which supporting element for closing the discharge space is at least partially softened by heat application, whereby held high part of the discharge vessel is lowered, however, in contrast to the prior art, the support member is arranged in the upright of the discharge vessel part completely outside the discharge space.
  • the support elements used for lowering the raised discharge vessel part contain a softening during the filling step Part that can lead to disturbing contamination of the residual gas atmosphere in the discharge space.
  • these impurities can occur because of the higher temperatures during the filling step and on the other hand, but also during the life of the lamp.
  • glass solder materials can be used for the softening parts. These may be, for example, held by organic binders glass flours. Thus, suitable viscosities can be achieved even at relatively low temperatures. With the binder materials, however, inevitable residual outgassing are connected, which disturb the purity of the residual gas atmosphere.
  • the invention is based on the recognition that these softening parts are basically indispensable only for holding up the discharge vessel part.
  • the support functions in the discharge space itself can, if at all necessary, also be fulfilled without such softening parts, although the cited prior art recommends such softening elements precisely with regard to this support function because of the uniformity of the system.
  • the purity of the residual gas atmosphere is in the foreground and any support elements within the discharge space can be produced with sufficient precision to be able to do without softening parts there, or at least provide them within the discharge space in lesser numbers.
  • the invention is therefore directed in particular also to such discharge lamps, in which no support elements are provided within the discharge space.
  • the discharge vessel By supporting elements completely outside the discharge space, which soften wholly or partially during the Be Scholl suitss, the discharge vessel can be kept high, the softening parts then lead only outside of the discharge space to outgassing and otherwise do not disturb the discharge space.
  • the softening parts lie in the closing of the discharge vessel outside the edge of the discharge space and have no contact with the discharge space. They should therefore in particular also be arranged outside a frame, for example a flat radiator. This is meant in this application by the term “completely outside”.
  • the discharge space itself is hardly affected by outgassing from external glass soldering materials or the like.
  • the discharge space becomes Even after lowering the discharge vessel part no longer affected by a further outgassing of now lying outside softening parts. This is of interest, because especially when lowering the highest temperatures occur and because of the unavoidable inertia even for a certain time.
  • the invention is not limited to performing the sealing of the two plates against each other or against a frame in the manner described above Glaslotmaterialien or other softening materials during the filling.
  • this approach is a preferred variant.
  • the contamination of the discharge medium by the softening material used thereby plays a somewhat smaller role, because the surface of this seal exposed to the discharge medium can be kept very small.
  • the softening parts of the support elements inevitably have a certain volume and thus also a certain surface. Finally, they should allow a movement of the raised plate over a macroscopic distance.
  • the flat radiators already mentioned form a preferred application for the invention.
  • lying outside the discharge space support element with the softening part (or more of such support elements) are outside the frame, but still be arranged between the plates.
  • the support element (s) according to the invention can only be process aids which do not play any role in the finished discharge lamp and are therefore separated again from the discharge lamp during manufacture.
  • the preferred construction of the support elements consists of at least two parts, of which the softening part sits on the plate lying down during the filling step and bears the non-softening part on it.
  • the contact surface between the upper part and the upper plate, which is preferably the ceiling plate be kept low, so that the light emission is little affected.
  • the sealing surface of the frame or another sealing surface of the discharge vessel is not meant.
  • the support elements according to the invention outside the discharge space should be used, because even by outgassing outside the discharge space still some impairment of the residual gas atmosphere in the discharge space is possible.
  • a small number of softening support element parts has the advantage that the weight of the discharge vessel part to be lowered is distributed over these few softening parts. The discharge vessel part to be lowered must then be weighted less or not at all.
  • the saving of weights for weighting leads to faster temperature changes during heating and cooling and to a more homogeneous temperature distribution and to a better utilization of space.
  • the number of softening parts may even be used to make an adjustment to the effective weight that pushes down the discharge vessel part to be lowered.
  • this effective weight is significantly greater for discharge vessels further down in the stack than for those located further up.
  • a variant may be favorable in which the part used to hold the plate softens overall, ie in other words, the element arranged between the top plate and the bottom plate softens overall.
  • one of the two plates may be shaped so that the plate itself has some support element function.
  • this variant besides the two plates and the intermediate softening support elements (support element parts), there are no further separate non-softening support element parts (in any case not on the support element points used for holding up).
  • the support elements may in fact be formed as one-piece components of the ceiling plate.
  • the support projections according to the invention outside the discharge space can also, as explained in the cited applications, run like ribs, so that they taper, as it were, only one-dimensionally. However, it is preferred that they also taper in a second dimension, that is to say they are substantially pointed.
  • the softening element may be provided with an opening into which the tip of an associated support projection is inserted, so that the placement of the ceiling plate on these softening elements is somewhat self-adjusting or at least can be done relatively safe.
  • the possible cavities in the softening elements should preferably be provided with an opening, so that no impurities are retained.
  • the boundary surfaces of pipe sections may have recesses or deviate in shape from the support projections. It can also be attached side holes.
  • pipe sections could be slotted axially.
  • the preferred material for the softening elements consists essentially of SF6 glass. If the viscosity of the softening parts is not or will not be very low, or if the part to be lowered is very light, then, as already mentioned, the upraised part can also be weighted to assist in lowering.
  • FIG. 1 is first on the respective FIG. 3 the two cited applications.
  • the same reference numerals have been used in the present applications, as far as they are comparable elements.
  • FIG. 1 shows a schematic plan view of a structure of a ceiling plate (3 in the FIGS. 2 and 3 ) and a bottom plate (4 in the FIGS. 2 and 3 ), which fully correspond to the structure of the cited applications except for the details explained below.
  • the ceiling plate 3 and the bottom plate 4 are in the outermost corner areas about in FIG. 2 good to be recognized and in FIG. 1 Separated from above in their substantially circular cross-section tube pieces 15 made of SF6 glass, on which rest the outermost support projections in the corners outside the rectangular format of the flat radiator.
  • the support projections have a designated 1'-1 "" circular approach in the planar parts of the ceiling plate 3 and extend from there tapered tapered with a tip 2'-2 "" at the bottom towards the bottom plate 4. In this case form the Peaks 2'-2 "" in the projection on the plate planes the centers of the circles 1'-1 "".
  • the ceiling plate 3 is a deep-drawn glass plate whose top in the contour largely corresponds to the bottom.
  • the support projections thus correspond here to the other support projections within the discharge space, ie in plan view FIG. 1 within the framework 8 described below. The details of this are already set forth in the two cited prior applications, so that reference may be made here.
  • FIG. 1 are designated with 5 electrode strips, which build a total of a complete electrode set for dielectrically impeded discharges, both the anodes and the cathodes are dielectrically coated and otherwise have no differences from each other.
  • the electrode strips 5 are each alternately fed to a right collecting terminal 10 and a left collecting terminal 11 and can be connected via an electronic ballast. Discharge areas are formed respectively in the next adjacent sections of adjacent electrode strips 5, so that they are in the in figure 3 lie with 6 designated discharge space sections.
  • 6 discharge space sections.
  • the support projections are each surrounded by identical arrangements of nearest adjacent discharge regions and vice versa (excluding edge regions) and that can be distinguished by the in FIG. 1 shown arrangement can draw different lines along which alternate discharge areas and supporting projections. Again, reference is made to the pre-registrations.
  • the circular projections 1 are not shown for the sake of clarity, so that the supporting projections are represented only by the tips 2.
  • the reference numeral 8 shows a frame-like structure which does not form a separate frame in this embodiment, but is also a deep-drawn projection of the ceiling plate 3. However, this is designed as a rib and not as a tapered cone.
  • the width of the frame rib 8 serves for a gas-tight connection to the bottom plate 4, which, as already explained, can be produced by a glass solder.
  • the farther outward line 9 shows the outer boundary of the frame, so to speak corresponds to the circle approach 1 in the support projections.
  • the lamp is to be filled before closing by gas-tight gluing or soldering of the frame 8 with the bottom plate 4, it is in the in the FIGS. 1 and 2 sketched state "jacked" by the outermost support projections 1'-1 "", 2'-2 "" placed in the corners of the pipe sections 15.
  • the tube projections 15 have a lateral slot, which is not shown in the drawing, so that their interior is miterutzt.
  • the pipe pieces 15 keep the ceiling plate 3 of its vertical length corresponding to about 2.5 mm high, so that the entire discharge space can be flooded with the desired discharge medium.
  • the vacuum oven used in this example can be used be heated until the softening temperature of the tube pieces 15 building SF6 glass is achieved, whereupon the pipe sections 15 are compressed by the weight of the weighted ceiling plate 3 if necessary to an irregular pile of material 16, so that finally the in FIG. 3 illustrated situation arises.
  • the pipe section FIG. 2 only an amorphous shaped small pile remained, which additionally adheres the support projection 1 ', 2' to the base plate 4.
  • the tip 2 'comes in FIG. 3 This does not necessarily have to be the case.
  • the support projections designed for the softening tube pieces 15 may also have somewhat smaller vertical dimensions, so that the tip 2 'does not completely cover the material 16
  • this displacement does not present a particular obstacle, as rib-shaped support projections could be different.
  • FIGS. 4 and 5 show a second embodiment. 4 also refers to a flat bottom plate, but on which a slightly modified ceiling plate 3 'should come to rest.
  • This ceiling plate 3 ' has a "knobby structure", to which reference is made to the previously cited applications 100 48 187.6 and 100 48 186.8.
  • SF6 glass tube section 15 ' By a suitably complementarily shaped bulge of the outermost edge of the ceiling plate 3 ', this can easily on the pipe section 15' or three or four of these pipe sections 15 'are placed. Over the greater part of the outer circumference of the discharge vessel thereby arise between the ceiling plate 3 'and the bottom plate 4 corresponding opening gaps.
  • the SF6 glass tube piece 15 ' softens at the corresponding temperature and collapses so that an in FIG. 5 indicated amorphous material accumulation 16 'remains.
  • the peculiarity of the glass tube piece 15 ' which here has a wall thickness of 0.3 mm with a diameter of 3 mm, is that it does not have to be exactly cut to the correct height dimension. Rather, it can be used here imprecise cut to length.
