Definitions
- the invention relates to a discharge lamp according to the preamble of claim 1.
- discharge lamp here encompasses sources of electromagnetic radiation based on gas discharges.
- the spectrum of the radiation can encompass both the visible range and the UV (ultraviolet) / VUV (vacuum ultraviolet) range and the IR (infrared) range.
- a phosphor layer can also be provided for converting invisible radiation into visible radiation.
- dielectric impeded electrodes These are discharge lamps with so-called dielectric impeded electrodes.
- the dielectrically impeded electrodes are typically implemented in the form of thin metallic strips, at least some of which are arranged on the inner wall of the discharge vessel. At least some of these inner wall electrodes are completely covered with a dielectric barrier layer in relation to the inside of the discharge vessel.
- a so-called unilaterally dielectric discharge is formed in preferably unipolar operation.
- all electrodes, ie both polarities, covered with a dielectric barrier layer are all electrodes, ie both polarities, covered with a dielectric barrier layer, a bilaterally dielectric discharge is formed in both unipolar and bipolar operation.
- At least one further functional layer is applied to the dielectric barrier layer and generally also to other parts of the inner wall of the discharge vessel, e.g. a layer of a phosphor or phosphor mixture and / or one or more reflection layers for visible radiation (light) and / or UV radiation.
- the purpose of the reflective layer is to bring visible light to the outside, i.e. only in a certain preferred direction of the lamp.
- the geometric shape of the discharge vessel is not subject to any particular restrictions. .
- trough-shaped or flat discharge vessels are common, the latter being u.a. Suitable as so-called flat lamps for the backlighting of liquid crystal screens (LCD).
- LCD liquid crystal screens
- the starting materials for both the reflector and the phosphor layer or layers are initially in the form of a powder with a suitable grain size. These powders are then applied as a suspension, usually with an organic binder, in a defined layer thickness to the inner wall of the lamp or to the other functional layers previously applied, for example electrodes and dielectric barrier layer.
- the layer thickness of the reflector or phosphor layer is controlled via the viscosity of the suspension, adapted to the respective coating process.
- the reflector and / or phosphor layer is present as a porous powder layer or layers.
- the closed nature of the reflector and / or fluorescent layer and its mechanical adhesion which decreases with increasing layer thickness, is an important prerequisite for achieving an optimal conversion of UV light into visible light.
- the dielectric barrier layer usually consists of glass frits, preferably lead borosilicate glass (Pb-B-Si-0).
- the discharge vessels of which each consist of an essentially planar base glass, such a front glass and optionally a frame the base glass is provided with a so-called solder rim, which likewise consists of a glass frit, preferably Pb-B-Si-0.
- This solder edge has the task of connecting the components of the discharge vessel (base glass, frame, front glass) in a vacuum-tight manner during the joining process. In this joining process, a temperature treatment takes place, in which the solder edge is defined as "melted", i. H. a defined viscosity is achieved.
- the layer which is arranged substantially immediately below the phosphor or reflection layer of the discharge lamp consists of a glass solder, the viscosity profile of which is irreversible with respect to the temperature. This feature is explained in more detail below. For the sake of simplicity, this layer is also referred to below as a “load-bearing” layer or “anti-ice floe layer”.
- essentially immediately below the fluorescent or reflection layer of the discharge lamp means that there should be as far as possible no further layer between the “supporting” layer and the porous fluorescent or reflective layer, at most only a very thin layer.
- the highest permissible The thickness of an additional layer depends on the condition that the porous phosphor or reflection layer arranged directly above does not tear open when the lamp is heated (heating, joining process, etc.) due to excessive "movement" due to the softening of the additional layer may. Depending on the nature and composition, the thickness of an additional layer should not exceed 100 ⁇ m, better 50 ⁇ m, typically 10 ⁇ m, ideally 5 ⁇ m.
- the "load-bearing" layer is preferably immediately below the phosphor or reflection layer arranged, ie without any additional layer between the "supporting" layer and the phosphor or reflection layer.
- This “load-bearing” layer (“anti-ice floe layer”) can be realized either by the barrier layer itself acting as a dielectric barrier for the discharge or by an intermediate layer arranged between the dielectric barrier layer on the one hand and the reflection and / or phosphor layer on the other hand.
- This intermediate layer should cover at least the entire dielectric barrier layer, but can also be applied “over the entire area”. For the effect according to the invention, it has proven sufficient if the thickness of this “load-bearing” intermediate layer is of the order of magnitude of approximately 10 ⁇ m or more.
- the typically pasty system is applied by standard methods such as spraying, dispensing, rolling, screen or stencil printing, etc.
- the dielectric barrier layer can be applied in strips to the individual electrodes (for one-sided and two-sided dielectric impediment) or - in the case of double-sided dielectric barrier discharge - "over the entire surface" by means of a single coherent barrier layer that covers all internal wall electrodes.
- the choice of the appropriate thickness The barrier layer is essentially determined by discharge physical requirements and is typically in the order of magnitude of 10 ⁇ m to several hundred ⁇ m, in particular between 50 ⁇ m and 200 ⁇ m, typically between 80 ⁇ m and 180 ⁇ m.
- the thickness of the barrier layer (s) for anodes or cathodes can also be selected differently, with unipolar pulse operation (WO94 / 23442) the barrier layer for the anodes being preferably thicker than that for the cathodes, although the layer thicknesses can also be the same his.
- the advantage of the first solution, ie the dielectric barrier layer is at the same time designed as a “supporting” layer (“anti-ice floe layer”), consists essentially in the fact that no additional manufacturing or printing step is required.
- the solution with the additional intermediate layer offers an additional degree of freedom for the targeted material selection of the dielectric barrier layer, in particular with regard to the dielectric and electrical properties influencing the discharge.
- the behavior of the glass solders usually used as a supporting glass layer for the porous layers will be explained first. Normally, even with Pb-B-Si-O glasses, the viscosity decreases with increasing temperature. This behavior is reproducible if the temperature was not so high that devitrification is already taking place. Reproducible means that the temperature range in which the glass softens at a defined viscosity, also with repetitions, i.e. after appropriate previous cooling, is almost constant.
- the glass solders proposed according to the invention do not show this behavior. Rather, their viscosity curve is irreversible with respect to temperature. Initially, the viscosity drops with increasing temperature. After that, however, the viscosity increases again, even if the temperature continues to rise.
- Bismuth borosilicate glass (Bi-B-Si-0) has proven to be a particularly suitable crystallizing glass solder.
- Other suitable crystallizing glass solders are, for example, zinc bismuth borosilicate glass (Zn-Bi-B-Si-0) and zinc borosilicate glass (Zn-B-Si-0).

- FIG. 1b shows a schematic illustration of a side view of the flat lamp from FIG.
- FIG. 1 c shows a partial sectional illustration of the flat lamp from FIG. 1 a along the line AA
- FIG. 2 shows a partial sectional illustration of a variant of the flat lamp from FIG. 1 a along the line AA
- Figures la, lb and lc show a schematic representation of a top view, a side view and a partial section along the line AA of a flat fluorescent lamp which emits white light during operation. It is designed as a backlight for an LCD (Liquid Crystal Display).
- LCD Liquid Crystal Display
- the flat lamp 1 consists of a flat discharge vessel 2 with a rectangular base, four strip-like metallic cathodes 3, 4 (-) and anodes (+), three of which are designed as elongated double anodes 5 and two as individual strip-like anodes 6.
- the discharge vessel 2 in turn consists of a base plate 7, a front plate 8 and a frame 9. Base plate 7 and front plate 8 are each gas-tightly connected to the frame 9 by means of glass solder 10 such that the interior 11 of the discharge vessel 2 is cuboid.
- the base plate 7 is larger than the front plate 8 in such a way that the discharge vessel 2 has a peripheral free-standing edge.
- the breakthrough in the front plate 8 is only for illustrative purposes and provides a view of a part of the cathodes 3, 4 and anodes 5, 6.
- the cathodes 3, 4 and anodes 5, 6 are arranged alternately and in parallel on the inner wall of the base plate 7.
- the anodes 6, 5 and cathodes 3, 4 are each extended at one end and are guided on the base plate 7 from the inside 11 of the discharge vessel 2 to the outside on both sides.
- the electrode strips 3, 4, 5, 6 merge into a cathode-side 13 and anode-side 14, bus-like external power supply.
- the two outer power supply lines 13, 14 serve as contacts for the connection to an electrical supply source (not shown).
- the electrodes 3-6 are completely covered with a sintered glass ceramic layer 61 made of Bi-B-Si-O (cf. FIG.
- the thickness of which is approximately 250 ⁇ m. On the one hand, this layer counteracts the "formation of ice floes".
- the sintered glass ceramic layer 61 simultaneously acts as a dielectric barrier layer for all electrodes 3-6. It is therefore a dielectric barrier on both sides.
- a reflector layer 62 is formed on the sintered glass ceramic layer 61 A thickness of about 4 ⁇ m is applied to TiO 2.
- a layer of phosphor mixture 63 is in turn applied to the reflector layer 62 and to the inner wall of the front plate 8 (the layers are not shown in FIG. which converts the UV / VUV radiation generated by the discharge into visible white light, a three-band phosphor with the blue component BAM (BaMgAl!
- the thickness of the phosphor mixture layer 63 is approximately 30 ⁇ m.
- the electrodes 3-6 including feedthroughs and external power supply lines 13, 14 are each formed as a coherent, cathode- or anode-side, conductor track-like, layer-like structure. These two layer-like structures and the subsequent other functional layers - dielectric barrier layer 61, reflection layer 62 and phosphor layer 63 are applied directly to the base plate 7 or front plate 8 by means of screen printing technology.
- the base plate 7 is fused to the frame 9 and this in turn to the front plate 8 using glass solder 10 to form the complete flat lamp 1.
- the joining process takes place, for example, in a vacuum oven.
- the interior 11 of the flat lamp 1 is filled with xenon with a filling pressure of 10 kPa.
- the two anode strips 5a, 5b of each anode pair 5 are widened in the direction of the two edges 15, 16 of the flat lamp 1, which are oriented perpendicular to the electrode strips 3-6, and asymmetrically exclusively in the direction of the respective partner strips 5b and 5a to.
- the mutual greatest distance between the two strips of each anode pair 5 is approximately 4 mm, the smallest distance is approximately 3 mm.
- the two individual anode strips 6 are each arranged in the immediate vicinity of the two edges 17, 18 of the flat lamp 1 which are parallel to the electrode strips 3-6.
- the cathode strips 3; 4 have nose-like, semi-circular extensions 19 facing the respectively adjacent anode 5; 6. They cause locally limited amplifications of the electric field and consequently that the delta-shaped individual discharges that arise during operation according to WO 94/23442 (not shown in FIG. 1 a) ignite only at these points.
- the distance between the extensions 19 and the respective immediately adjacent anode strip is approximately 6 mm.
- the radius of the semicircular extensions 19 is approximately 2 mm.
- Figure 2 shows a partial sectional view of a variant of the flat lamp from Figure la along the line AA. Identical features are provided with the same reference symbols.
- an additional 12 ⁇ m thick intermediate layer 64 made of Bi-B-Si-O is arranged between the dielectric barrier layer 61 ′ and the reflection layer 62.
- the dielectric barrier layer 61 'here consists of lead borosilicate glass.
- the function of the crystallizing layer, which prevents the "formation of ice floes" is thus taken over by the intermediate layer 64.
- a further reflection layer made of Al 2 O 3 is arranged between the TiO 2 layer and the phosphor layer. In this way the reflection effect is improved.
- the thickness of the Al 2 O 3 layer is approximately 5 ⁇ m.
- the layers shown schematically in FIGS. 1c and 2 do not necessarily have to be extended over the entire surface of the base plate. It is only essential that at least the respective electrode in question is completely covered with the corresponding layers. In the case of one-sided dielectric disability, only the electrodes of one polarity, preferably the anodes, are covered with a “load-bearing” dielectric layer.
- the individual layers do not necessarily have to be completely flat, as is shown in a simplified manner in FIGS. 1c and 2. Rather, the individual layers, in particular the very thin layers, can also be uneven in practice. This is particularly evident when one or more layers are thinner than the electrodes and the layer (s) consequently still clearly show the surface shape of the base plate with the electrodes.
- it is a tubular aperture lamp.
- the main difference is that of the Flat lamp from Figure 1 in the manufacturing process matched to the changed vessel shape.
- the phosphor is applied to the inner wall or the functional layers previously arranged thereon by means of slurries.
- the basic sequence and function of the individual functional layers, in particular the effect according to the invention of the “load-bearing” layer, which prevents “ice floe formation”, correspond to that from FIG. 1.
