Definitions
- This invention relates to discharge lamp systems designed for dielectrically impeded discharges.
- discharge lamp systems at least a part of the electrodes is separated from a discharge medium by a dielectric layer, and if it is possible to distinguish between cathodes and anodes, at least the anodes.
- This invention is based on the problem of improving the Mög ⁇ possibilities for dimming of such discharge lamp systems.
- a lamp system with at least one discharge vessel, at least one electronic ⁇ 's ballast and at least two can be acted upon by the ballast separated with power Elect ⁇ roden groups, wherein at least a part of the electrodes in the electrode groups of a discharge medium in the Discharge vessel is separated by a dielectric layer and wherein at least one electrode group per Entla ⁇ tion vessel is provided, characterized in that the lamp system is adapted to operate in a dimming operation, the electrodes in groups sequentially and with a frequency of at least 16 Hz, and a corresponding method for operating a Lampensys ⁇ tems.
- the basic idea of the invention is to be able to operate the lamp system of the electrode groups also with only a part of the electrodes, namely by dividing the electrodes into electrode groups and separate operability. In this case, of course, for example, the full load operating conditions for the Discharge between respective electrodes yet implemented a significantly lower performance, because another part of the electrodes remains out of service.
- the electrode groups should be sequentially, i. H. be operated sequentially, with such high sequence frequencies are selected that the human eye can not follow. In each sequence clock, therefore, only a part of the electrode groups is operated, wherein this part is changed from sequence clock to sequence clock and these changes take place so quickly that the human eye performs an averaging.
- frequencies of at least 16 Hz, preferably at least 18 Hz, 24 Hz, 30 Hz, 40 Hz, 50 Hz and particularly preferably at least 60 Hz are to be selected.
- the sequential operation must not Congresserwei ⁇ se in any sequence clock only an electrode group Subject Author ⁇ fen.
- the electrode groups operating during a sequence clock need not necessarily be out of service in the preceding and / or subsequent sequence clock, although this is desirable to realize smaller power levels.
- the Sequenz réellenfol ⁇ ge does not necessarily follow a recur ⁇ the same pattern, although this is also desirable easier to implement because. In the simplest case, it may also be an alternating operation of two electrode groups.
- lamp system here comprises at least one ballast with at least one discharge vessel and at least two electrode groups.
- a plurality of discharge vessels are provided - A -
- the invention can also be realized by a sequential operation of the respective electrodes of a plurality of discharge vessels, ie, basically a sequential operation of the discharge vessels . It could thus for example also the set of electrodes of a jewei ⁇ then discharge vessel of an electrode group entspre ⁇ chen.
- at least two electrode groups are provided per discharge vessel, which are operated sequentially with respect to each other.
- a common ballast for all electrodes and thus discharge vessels of a lamp system is preferably provided. The same can then be switched back and forth between the electrode groups that are in operation for operation in a sequence cycle.
- a previously known and advantageous arrangement of the electric ⁇ is divided row-wise, in particular having essentially of electrode structures apart to define individual discharge parts, a straight line shape and the substantially parallel lines. Such arrangements are known and particularly advantageous in so-called.
- Flat ⁇ radiators ie relatively flat discharge vessels with plate-like shape.
- the electrode groups can be nested line by line. By this is meant that the electrodes of an electrode group do not correspond with each other ssenbe ⁇ nachbarter electrodes a set which are to be separated from the next adjacent to each other likewise electrode of another electrode group in the sense of separate "blocks". Rather, preferably more than a minimum number of external electrodes of different electrode groups should also be in a neighborhood ratio, ie nested arrangements should be selected. This verbes ⁇ sert the homogeneity of the overall illumination in the operation of only a part of the electrode groups.
- the electrodes can also be separated along a line, that is, one row can contain a plurality of electrodes with electrical separation therebetween. These electrodes of the same row then preferably belong to different electrode groups. Also, this group assignment of different line parts can be nested in a sense. So one imagines examples play, a division of the line into left, center and right field before, the left area then could belong to different Elektrodengrup ⁇ pen from line to line, so to the electrode group of the left Be ⁇ empire a line of right or middle section of another line.
- the advantage here is a connection of the electrodes and electrode parts via a multilayer package of printed conductors, the is preferably arranged on the side facing away from the discharge vessel Sei ⁇ te.

- FIG. 19 shows yet another variant of FIG. 16.
- FIG. 1 shows a schematic plan view of a lamp system according to the invention.
- 1 denotes a substantially square flat radiator, which is designed for dielectrically impeded discharges.
- the ⁇ NEN shown in plan view and substantially sine wave-like electrodes 2, which are arranged in the central straight and line by line and by an electronic Ballast 3 are supplied.
- 4c 4d respectively to each second electrode, as the cathode, and external supply lines, - - this case are external to ⁇ lead wires 4a, 4b - located Left Right located - in each case to the intermediate electrodes.
- the supply lines 4a-4d are shown only symbolically and show that both the cathodes and the A-nodes are divided into alternating groups.
- the cathodes and anodes come to jewei- time sections of the sinusoidal waveforms, thus eliminating there ignited corresponding individual discharges ⁇ to burn and what is known.
- the assignment to cathodes and anodes is here arbitrary insofar as the electrode structures just as well permit a reverse assignment and are in particular also designed for bipolar operation.
- the electrode groups are nested here line by line. This means that if one of the two Lektrodenopathy is in operation, light over the surface of ge ⁇ entire flat radiator 1 distributed stripes and not just the lower, upper, right or left half.
- the ballast 3 is designed to dim the operation of the individual groups by reducing the pulse heights of a pulsed power input and additionally or alternatively also the pulse lengths or also increasing the pulse intervals. By complementing each other, a very wide dimming range can be realized.
- FIG. 2 largely corresponds to FIG. 1. The difference is that three electrode groups are provided here, which results from the outer supply lines drawn on the left and right. Again, there is a line-by-line interleaving, in a cyclic order of the three groups.
- the respective cathode leads are connected 4a - 4c and 4d with the Anodenzulei ⁇ obligations - designated 4f.
- Figure 3 and Figure 4 also largely correspond Fi gur ⁇ 1.
- the electrodes are also the line length divided what is to be represented by the average per ⁇ wells dilution of the sine-wave electrode strip.
- the electrode groups - two in number as in FIG. 1 - are not only interleaved line by line, but also in the sense of an alternating assignment to the right and left half.
- FIG. 4 likewise shows centrally interrupted electrode strips 2 with two electrode groups as in FIG. 3. However, the electrodes are contacted only from their outer ends and not from the center. For the sake of clarity, the outer supply lines here and below are no longer designated by reference numerals.
- FIG. 5 largely corresponds to FIG. 4, but here three electrode groups are provided, two of them having five pairs of individual electrodes corresponding in each case to one half of the row, and a group having four such pairs.
- the arrangement is in turn alternating with respect to the membership of the right and left half and interleaved cyclically line by line.
- FIG. 6 shows a variant in which the electrodes are partially separated along the length of the line, but not for the other part.
- the electrodes are arranged alternately in the region of the split version and, in turn, are interleaved cyclically line by line. Again, there are three electrode groups.
- FIG. 7 shows another variant with three electrodes ⁇ groups, with undivided along the line length electrodes.
- the electrode strips 2 are designed differently according to cathodes and anodes.
- the cathodes are designated 2a, the anodes 2b.
- the cathodes 2a and the anodes 2b occur in pairs, apart from the outermost cathodes 2a.
- the cathodes 2a tra ⁇ gene nose-like projections to the next adjacent anode 2b, which are arranged alternately within the respective cathode pair 2a. These projections serve to locate the individual discharges similar to the extreme points of the sine waveform of the previous embodiments.
- the flat radiator lamp 1 is thus designed for a unipolar operation.
- FIG. 8 shows an embodiment which is similar to that of FIG.
- the basic electrode structure having Ka ⁇ methods 2a and 2b anodes and division into three groups of electrodes are identical. However, here the straight cell-shaped electrodes 2a, 2b are subdivided in a lengthwise manner, similar to that in FIG. 5, in one third. In the shape shown in FIG. 8, these electrode parts are contacted, as in FIG. 3, partly by the edge, partly by the middle .
- the group assignment is line by line here and interleaved with a member of the lin ⁇ ken, center and right third. In FIG. 8, for the sake of clarity, only the upper part of the electrode structure with the corresponding supply lines has been drawn.
- Figure 9 shows the electrode structure of Figure 8 in a schematic plan view of the left and right to a pas ⁇ send sectional view designated by 5, 6 and 7 on ⁇ successive components of the entire lamp system is symbolic.
- 6 designates a multilayer board with a stack of interconnect layers and interposed insulators with via contacts. requirements.
- 7 denotes a discharge vessel. The the discharge vessel 7 facing uppermost layer of the Mehrschich ⁇ tenstapels 6 is formed in the manner shown left in FIG 9 as electrode structure and coupled through the discharge vessel wall to the discharge medium to. 5 again symbolically a built on the Mechanismge ⁇ put side of the multilayer board electro ⁇ African ballast.
- Whose electronic components can be mounted directly in the multilayer board and, as the rectangular representation in Figure 9 suggests, be protected with a cover.
- FIG. 10 largely corresponds to FIG. 9, wherein here the discharge vessel is subdivided into nine individual discharge vessels. These are visible in the left-hand illustration in the top-view in the form of individual squares, above all on the basis of the thin vertical lines; in the right-hand illustration, three of the individual discharge vessels are shown and labeled 7a-7c.
- the 11 and 12 again show variants of Figure 9.
- the discharge vessel is divided into twelve over the line length through, but only one electric ⁇ denrect comprehensive individual discharge vessels 7a, 7f and 7k and other non-designated.
- the individual discharge vessels are additionally subdivided into thirds according to the row length, so that there are a total of 36 pieces.
- the sectional view shows the left third, wherein the single discharge vessels are ⁇ as denoted by 7a, 7f, 7k.
- FIG. 13 to 19 show various electrode structures each ⁇ a time sequence of the "light-emitting pattern" of a flat radiator 1.
- time points 1 to 4 the time is plotted continuously from left to right.
- FIG. 13 is based on an electrode structure as in FIG. 1 (but rotated by 90 ° with eight instead of seven electrode pairs).
- the first, third, fifth and seventh electrode pairs are to be counted from left to right as a first group in operation and the second, fourth, sixth and eighth electrode pair as a second group to be out of operation.
- the dark fields thus mean a local discharge operation.
- time 3 the situation of time 1 is present again, at time 4 that of time 2.
- times 1 and 2 like times 3 and 4, together form a first or second sequence of sequential operation.
- the total lamp power is considered halved at full load operation of the individual groups.
- FIG. 14 shows a very similar representation, but for an electrode structure comparable to FIG. 2, namely, FIG. with three groups.
- the first, fourth, and seventh electrode pairs operate, forming a first group.
- the two ⁇ te, the fifth and the eighth electrode pair as a second group in operation; and at time 3, the third and sixth electrode pairs forming a third group.
- Time 4 again corresponds to time 1, so that therefore the first three times together a sequence bil ⁇ den.
- the fact that at the time 3 only two electrical dencrue in operation, at time 1 and time 2 ⁇ point but three, can lead to small brightness fluctuations ⁇ . Due to the relatively high frequency, these are no longer resolvable for the eye. If, as already mentioned, additionally within the E lektrodenement a dimmed by a Parameterva ⁇ riation the pulsed mode of operation is carried out, these differences can be so well balanced.
- FIG. 15 shows a checkerboard pattern -like group structure with two electrode groups, ie sequences from respectively two different points in time. This electrode structure corresponds in principle 3 or 4, but especially along the line length ⁇ boxes much more ver.
- FIG. 16 is based on a FIG. 3 or 4 electrode structure which is quite directly comparable (but again with eight line pairs), ie with two electrode groups.
- Figure 17 is a Figure 6 similar electrode structure with partly along the line length up part ⁇ th and partly through the electrode lines from (re- order with a line more than in Figure 6). It is here three groups provided, one consisting of the time in 1 and 4 in operation, consisting of effetive ⁇ Henden electrode lines and the other two groups consist of half-row lines formed by central division.
- Figure 18 largely corresponds to Figure 16, refers depending ⁇ but on an electrode structure with three groups, that is similar to FIG. 5
- Figure 19 is like Figure 18, but assumes a Auftei- development of electrode pairs along the row length in DRIT ⁇ tel, and thereby of the three groups.
