Definitions
- the present invention relates to a production method for a discharge lamp which is 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 can also be formed by a discharge vessel wall.
- the discharge vessel has a base plate and a cover plate, which are connected by a frame running in the area of the outer edge of the plates, which can also be part of one of the two plates.
- the present invention is not restricted to the flat radiator design.
- it is known to support elements between this the plates that serve to shorten the effective bending lengths and mechanically stabilize the discharge vessel. This is important because of the partially larger formats of the flat radiators, particularly in the case of backlighting of flat display devices, and also because of the negative pressure that is often present in the discharge medium.
- the present invention is also not restricted to discharge lamps with such support elements.
- a sealing surface provided on the frame of the flat radiator can also be provided with a material that softens to such an extent that this sealing surface, when the corresponding parts are brought into contact with one another, creates a sealing connection.
- the discharge space can be closed automatically during the filling step.
- the charging step namely 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 first holding the ceiling lamp of the flat radiator high above the frame, so that an opening for filling the discharge space is kept free between the underside of the ceiling plate and the top of the frame. If the aforementioned parts of the support elements soften sufficiently at a corresponding temperature, the ceiling plate is lowered by gravity because these support element parts are flattened. By placing 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 often used for both the sealing surface and the softening support element parts.
- the materials that can be used the structure of the support elements, the typical temperatures and the favorable viscosities of the various parts of the support elements, reference is made to the disclosure content of the document mentioned, which is included in this application by reference.
- the present invention is based on the problem of specifying a production method for a discharge lamp designed for dielectrically impeded discharges which is improved with respect to the step.
- the invention relates to a production method for such a discharge lamp, in which, during a filling step preceding a closing of the discharge space, one of at least two parts of the discharge vessel is held up by a support element, which support element for closing the discharge space is at least partially softened by the application of heat. whereby the part of the discharge vessel held up is lowered, but in contrast to the prior art, the support element is arranged completely outside the discharge space when the part of the discharge vessel is held up.
- the support elements used for lowering the discharge vessel part held up contain a dilated during the filling step. - zi ⁇
- glass solder materials can be used for the softening parts. These can be, for example, glass powder held by organic binders. Suitable viscosities can thus be achieved even at relatively low temperatures. However, inevitable residual outgassing is associated with the binder materials, which disturbs the purity of the residual gas atmosphere.
- the invention is now based on the knowledge that these softening parts are basically only indispensable for holding up the discharge vessel part.
- the support functions in the discharge space itself can, if at all necessary, also be performed 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 that any supporting elements within the discharge space can be manufactured with sufficient precision to be able to dispense with softening parts there, or in any case to provide them in smaller numbers within the discharge space.
- the invention therefore also relates in particular to those discharge lamps in which no support elements are provided at all within the discharge space.
- the discharge vessel part can be held up well by supporting elements completely outside the discharge space, which soften in whole or in part during the filling step, the softening parts then only leading to outgassing outside the discharge space and also not disturbing the discharge space.
- An arrangement outside the discharge space also means in particular that the softening parts, when the discharge vessel is closed, lie outside the edge of the discharge space and have no contact with the discharge space. In particular, they should also be arranged outside a frame, for example a flat radiator. In this application this is meant by the term “completely outside”.
- the discharge space itself is hardly affected by outgassing from outside glass solder materials or the like.
- the discharge Even after the discharge vessel part has been lowered, space is no longer affected by further outgassing of the softening parts which are now located outside. This is of interest because the highest temperatures occur when lowering and because of the unavoidable inertia they also persist for a certain time.
- the invention is not limited to sealing the two plates against one another or against a frame in the manner described above using glass solder materials or other softening materials during the filling step.
- this procedure 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 which is 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 enable the plate held up to be moved over a macroscopic distance.
- the support element with the softening part (or several such support elements) lying outside the discharge space according to the invention can then lie outside the frame, but can still be arranged between the plates. Suitable extensions of the plates can also be provided, which are removed again in a later step of the production process, for example broken off.
- the support element (s) according to the invention can only be process aids that play no role in the finished discharge lamp and are therefore separated from the discharge lamp again 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 at the bottom during the filling step and carries the non-softening part on itself. As a result, for example, the contact area between the upper part and the upper plate, which is preferably the ceiling plate, can be kept small, so that the light radiation is little impaired.
- the sealing surface of the frame or another sealing surface of the discharge vessel not being meant here.
- the support elements according to the invention should be used outside the discharge space, because a certain impairment of the residual gas atmosphere in the discharge space is also possible due to outgassing outside the discharge space.
- 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 then has to be weighed down less or not at all.
- the number of softening parts can even be used to adapt to the effective weight that depresses the discharge vessel part to be lowered. If several discharge vessels are stacked one on top of the other, this effective weight is significantly greater for discharge vessels located further down in the stack than for those located further up.
- these four support elements should be designed and used in this way.
- these four support elements in the four corners of a flat radiator discharge vessel with rectangular ger plate shape are arranged so that the plate to be held up is supported in the area of its outer corners.
- three support elements are sufficient to support a plate over a large area.
- the opening available for filling the discharge space is no longer on all sides, but this does not necessarily have to be a problem. In particular, this opening can be made somewhat higher than in the case of an opening on all sides, so that a sufficient cross section is available.
- a variant can be favorable in which the part used to hold up the plate softens overall, in other words in which in other words the element arranged between the ceiling plate and the base plate softens overall.
- one of the two plates can be shaped in such a way that the plate itself has some supporting element function.
- this variant in addition to the two plates and the intermediate softening support elements (support element parts), there are no further separate non-softening support element parts (at least not at the support element locations used for holding up).
- support elements integrated in the panels in particular in the ceiling panels, reference is made to two earlier patent applications by the same applicant, namely DE 100 48 187.6 and DE 100 48 186.8, the disclosure content of which is hereby included.
- the support elements can namely be designed as one-piece components of the ceiling plate.
- the softening parts can be be placed.
- the positioning effort is limited to the relatively small number of these places according to the invention.
- the support projections according to the invention outside the discharge space can, as explained in the cited applications, also run in a rib-like manner, that is to say only taper one-dimensionally, so to speak. However, it is preferred that they also taper in a second dimension, that is to say essentially taper.
- the softening element can be provided with an opening into which the tip of an associated support projection is inserted, so that the mounting of the ceiling plate on these softening elements is somewhat self-adjusting or can in any case take place relatively safely.
- the cavities possible in the softening elements should preferably be provided with an opening so that no impurities are retained.
- the boundary surfaces of pipe sections can have recesses or differ in shape from the support projections. Lateral holes can also be provided. Pieces of pipe could also be axially slotted.
- a contacting arrangement between the support projection and the base plate is then preferably provided, which is used for the stabilizing effect, in particular when the discharge medium is underpressure. often enough.
- the preferred material for the softening elements consists essentially of SF6 glass. If the viscosity of the softening parts is not or should not become very low or if the part to be lowered is very light, the part held up can, as already mentioned, also be weighted to assist the lowering. Description of the drawings
- Figure 1 is a schematic plan view of a flat lamp discharge lamp according to the invention with symbolized contact points of the support elements with the base plate and softening parts in the support elements in the corners;
- FIG. 2 shows a schematic side view of a support element from one of the corners in FIG. 1 before the part provided for this is softened;
- Figure 3 is a view corresponding to Figure 2 after softening this part
- FIG. 4 shows a representation comparable to FIG. 2 for a further exemplary embodiment
- FIG. 5 shows a representation corresponding to FIG. 4 after the supporting element in FIG. 4 has softened.
- FIG. 1 With regard to FIG. 1, reference is first made to the respective FIG. 3 of the two cited prior applications. The same reference numbers have been used in the present applications for clarification insofar as they are comparable elements.
- FIG. 1 shows a schematic plan view of a structure consisting of a ceiling plate (3 in FIGS. 2 and 3) and a base plate (4 in FIGS. 2 and 3), which correspond completely to the structure of the cited applications except for the details explained below.
- the top plate 3 and the bottom plate 4 are separated in the outermost corner areas via tube pieces 15 made of SF6 glass, which can be seen clearly in FIG. 2 and are drawn in from FIG. 1 in their essentially circular cross section, on which the outermost support projections in the corners outside the rectangular format of the flat radiator.
- the support projections have a circular extension designated 1'-1 "" in the flat parts of the ceiling plate 3 and extend from there in a tapered shape with a tip 2'-2 "" at the lower end towards the base plate 4.
- the ceiling plate 3 is a deep-drawn glass plate, the top of which largely corresponds to the underside of the contour.
- the support projections here correspond to the other support projections within the discharge space, ie in the plan view from FIG. 1 within the frame 8 described below. The details of this are already set out in the two earlier applications cited, so that reference can be made here.
- FIG. 1 there are 5 electrode strips, which in total build up a complete set of electrodes for dielectrically impeded discharges, both the anodes and the cathodes being dielectrically coated and also having no other differences.
- the electrode strips 5 are alternately fed to a right common connection 10 and a left common connection 11 and can be connected to an electronic ballast. Discharge areas are formed in the next adjacent sections of adjacent electrode strips 5, so that they are in the in the figure 3 with 6 designated discharge space sections.
- the support projections are each surrounded by the same arrangements of next-adjacent discharge areas and vice versa (excluding edge areas) and that the arrangement shown in FIG. 1 allows different lines to be drawn along which discharge areas and support projections alternate.
- the circular projections 1 are not shown in FIG. 1 for the sake of clarity, so that the support projections are represented only by the tips 2.
- reference numeral 8 shows a frame-like structure, which in this exemplary embodiment does not form a separate frame, but rather 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 base plate 4, which, as already explained, can be produced by a glass solder.
- the line 9 lying further out shows the outer limit of the frame, so it corresponds to a certain extent to the circular approach 1 for the support projections.
- the lamp is to be filled with the base plate 4 by gas-tight gluing or soldering of the frame 8 before it is closed, it is “jacked up” in the state outlined in FIGS. 1 and 2 by the outermost supporting projections 1'-1 "", 2'-2 "" are placed in the corners on the pipe pieces 15.
- the pipe projections 15 have a lateral slot, which is not shown in the drawing, so that their interior is also included.
- the pipe pieces 15 hold the ceiling plate 3 of its vertical length correspondingly by approximately 2.5 mm high, so that the entire discharge space can be flooded with the desired discharge medium.
- the tip 2 'in FIG. 3 comes to rest against the base plate 4 (likewise 2 "- 2" "). This does not necessarily have to be the case.
- the support projections designed for the softening pipe pieces 15 can also have somewhat smaller vertical dimensions , so that the tip 2 'does not have to completely displace the material 16 beneath it, but due to the pointed shape, this displacement does not constitute a particular obstacle, which could be different with rib-shaped support projections.
- FIG. 4 shows a second embodiment. 4 also designates a flat base plate, on which, however, a somewhat modified ceiling plate 3 'is intended to lie.
- This cover plate 3 ' has a “knob structure”, to which reference is made to the applications 100 48 187.6 and 100 48 186.8 already cited earlier.
- the outer region of the cover plate 3 ′ rests on a plate parallel with its axis direction before the filling step is completed lying SF6 glass tube piece 15 '.
- the peculiarity of the glass tube piece 15 ' which here has a wall thickness of 0.3 mm with a diameter of 3 mm, lies in the fact that it does not have to be cut to length in order to specify the correct height dimension. Rather, imprecise cut goods can be used here.
- comparatively small amounts of material can be used with thin-walled pipes, the opening of the pipe resulting from the plate-parallel axis position without slitting.
- the molded-in receptacle on the part of the ceiling plate 3 ' makes the construction shown in FIG. 4 relatively stable and vibration-proof.
- a tube with a different cross-sectional shape or a solid rod could also be used instead of the tube 15 '.
- the material 16 'baked or fused to the base plate 4 and the cover plate 3' also ensures additional stabilization of the connection between the two plates 3 'and 4, independently of the seal 18 of the integrated frame.
