Definitions

  • the present invention relates to a discharge lamp designed for dielectrically impeded discharges.
  • the discharge lamp has a discharge vessel filled with a discharge medium and an electrode arrangement with at least one anode and at least one cathode. Since the discharge lamp is designed for dielectrically impeded discharges, a dielectric layer is located at least between the anode and the discharge medium. Thus, the anode and the cathode define therebetween a discharge gap in which dielectrically impeded discharges can be generated.
  • anode and cathode are not to be understood as meaning that the discharge lamp would only be suitable for unipolar operation. It can also be designed for a bipolar power supply, in which case there is at least no electrical difference between the one or more anodes and cathodes. Thus, in this application, the statements for one of the two electrode groups in the case of a bipolar power supply apply to both electrode groups.
  • the discharge lamps considered here have a large number of promising applications.
  • An important example is the backlighting of flat-panel systems, in particular LCDs (Liquid Crystal Displays).
  • discharge lamps for dielectrically impeded discharges in a variety of sizes and geometries can be performed while achieving a relatively high efficiency while avoiding the typical disadvantages of classical discharge lamps with mercury-containing filling, they are promising candidates for a large number of different technical applications.
  • the invention is based on the technical problem of improving a discharge lamp for dielectrically impeded discharges so that their possible uses be further increased and specify a corresponding operating method for the discharge lamp.
  • the invention is based on the recognition that there are a number of applications in which, in addition to or instead of the qualities initially required, it is essential that the discharge lamp can be operated with a very low luminous flux. For this purpose, it was necessary in the invention to improve the properties of the lamp so that it allows the coupling of very low power supply.
  • the discharge distance between the electrodes is chosen to be particularly small. According to the invention, this discharge distance between cathodes and anodes is 3 mm or below, preferably 2 mm, 1.5 mm, 1 mm, 0.8 mm or below, and more preferably 0.6 mm and below.
  • the main advantage of the short discharge distances is that they allow for a pulsed-operated power supply particularly long dead times between the individual active power pulses, without causing locally undesirably high current densities.
  • the dead times between discharges are greatly extended, thereby reducing the coupled into the lamp average power and thus the average radiated light output, at least as long as the energy injected per pulse amount is not compensating increased. Rather, it is preferred in the invention that - even with a power setting still discussed below - the energy coupled in per active power pulse remains substantially constant, ie. H. not consciously changed. Of course, it may change somewhat due to the electrical parameters and the discharge parameters changed as a result of the dead time extension, but this does not detract from the invention.
  • the invention thus relates to an operating method in which the dead time between the active power pulses can be adjusted to adjust the lamp power, which corresponds to a dimming method in case of adjustability during lamp operation.
  • the invention is directed to an operating method in which, as stated above, particularly long dead times are used, in particular longer than the values already mentioned. Included is also an operation of the discharge lamp with only this low power or a long dead time.
  • one or more further discharge spacings are provided in a discharge lamp in addition to the discharge gap according to the invention provided. It is intended in particular, in combination with a below described Zündosfunktion or regardless of being able to operate these electrode groups with different discharge distances separately. Then, in operation, different power levels can be operated with different electrode groups or different combinations of electrode groups, and thus each optimal operating parameters can be selected.
  • larger discharge gap electrode groups can be used for higher discharge lamp performance, because better efficiency is generally achieved at the larger discharge spacings.
  • the discharge gaps according to the invention are not really advantageous in terms of the efficiency of light generation. However, this is generally of lesser interest when particularly low power is desired, where the absolute losses due to degraded efficiency are low anyway.
  • the discharge lamp is preferably designed so that the power ranges possible with the different discharge spacings overlap one another.
  • the dimming behavior of a ballast with corresponding power jumps to compensate for efficiency jumps when switching between discharge intervals but also these small discontinuities can be corrected if they are disturbing.
  • a particular embodiment of the invention consists in that, in addition to an anode and a cathode (wherein further anodes and cathodes may be present), a further electrode is provided, which is associated with the anode and the cathode for dielectrically impeded discharge is, namely the cathode in the invention according to the small discharge gap and the anode in a larger discharge gap.
  • the additional electrode can act as an anode in view of the small discharge gap and as a cathode in view of the larger discharge gap.
  • the discharges across the smaller and the larger discharge gap not only together, d. H. in the sense of macroscopic times simultaneously, but that between the active power pulses for the two discharges beyond a fixed phase relationship exists, which is selected in view of the described Zündunterstützungsfunktion the discharge over the smaller distance for the discharge over the greater distance.
  • the discharge over the small discharge gap is very easy to ignite because of this short discharge gap, even at low power levels.
  • the electrode under consideration here must be covered with a dielectric because, among other things, it acts as an anode.
  • the measures according to the invention already described are supplemented by an embodiment of the electrode arrangement in favor of dimmability even at conventional discharge spacings.
  • the electrode arrangement is designed to be inhomogeneous along a so-called control length, so that a burning voltage of the discharges changes within the control length.
  • a sinusoidal profile of at least part of the electrodes is preferred, the inhomogeneity being a change in the discharge distance and thus the burning voltage.
  • the method according to the invention for power adjustment or dimming method uses the dead time between individual active power pulses of a pulsed power supply as parameters for power influencing.
  • two specific variants for the design of a corresponding electronic Vorschalts réelles are preferred. These two variants are summarized in claims 14 and 15.
  • the electronic ballasts described there according to the Flußwandler850 or according to the blocking / Flußwandlertama are clocked via a primary circuit switch - there with T Q denoted - which is switched by a control device - there SE -.
  • the dead time can be influenced by appropriate intervention in the control logic of this control device with a suitable selection of the electrical parameters of the ballasts and the discharge lamp.
  • the value of the dead time can be influenced by an external influencing of a reference variable of this control device for the time definition. Details of this are obvious to the person skilled in the art.
  • the invention relates to a lighting system with such a discharge lamp and a correspondingly designed electronic ballast, the latter not necessarily according to claims 14 and 15.
  • FIG. 1 illustrated electrode assembly as the first embodiment of the invention, twelve numbered electrode strips are shown, which are deposited on a wall, not shown, of a flat radiator discharge vessel. You can of course in different ways on different walls, eg. B. the opposite plate inside a flat radiator discharge vessel may be deposited.
  • the electrode strips 1 and 2, 5 and 6, 7 and 8 and 11 and 12 each have a distance of 4 mm from each other, which is a larger discharge distance in the sense of the introduction.
  • the electrode strips 6 and 7 are spaced from each other by about 2-3 mm.
  • the outer electrode strips 1 and 12 and the middle electrode strips 6 and 7 are at a positive potential, so are connected as anodes.
  • the inner electrode strips 3, 4, 9, 10 in the respectively closely spaced groups of four are at negative potential, ie are cathodes.
  • the remaining electrode strips 2, 5, 8, 11 are at a potential between the aforementioned potentials much closer to the negative potential. This is in FIG. 1 for simplicity, indicated with 0.
  • the respective potentials can be selectively switched, ie the electrode strips 1-12 need not be electrically supplied at the same time.
  • discharges in a dimming range of the flat radiator with very low powers or luminous fluxes discharges can be operated via the discharge spacings between the electrode pairs 2 and 3, 4 and 5, 8 and 9 as well as 10 and 11. Since these 0.4 mm electrode spacings are extremely short, these discharges are very easy to ignite and, according to this invention, can even be driven with dead times in the range of 1 ms and above. By shortening or lengthening the dead times, the flat radiator can be dimmed even at very low power without problems.
  • the efficiency of the discharges over the short discharge gap of 0.4 mm in this example is about 5 times worse than the more powerful discharges over the larger discharge gap of 4 mm.
  • discharges can be ignited and operated, which in themselves correspond to the state of the art, and emit a high luminous flux with good efficiency to let.
  • relative dimmer power changes of at least 10: 1 are typically possible. With appropriate design of the discharge distances and adjustable dead times also values of 20: 1, 50: 1 or even 100: 1 and more are achievable. It should be noted that by the already mentioned degradation of the efficiency in the discharges over the short discharge distances by said relative power changes, actual relative luminous flux changes enhanced by the factor of deterioration of the efficiency can be achieved. A typical value for this factor at a discharge distance of 0.4 mm is 5. Thus, with the invention, relative luminous flux changes of 50: 1, 500 to 1 at best be achieved.
  • the illustrated electrode assembly may be operated simultaneously with discharges over said long and said short discharge distances.
  • the term at the same time does not refer to the individual active power pulses, but only to macroscopic times in the sense of switching the discharge lamp on or off.
  • the electrons accumulated by the discharges over the short distances on the intermediate potential electrode strips 2, 5, 8, 11 come to the aid of the ignition of the discharges over the long discharge spacings.
  • the dimmability of the discharges over the long discharge spacings can already be substantially increased to smaller powers.
  • the flat radiator can only be operated with the discharges over the short discharge distances.
  • the electrode strips 3, 4, 9 and 10 are to be understood in each case as double-executed cathode.
  • This cathode separation can also be omitted be as the second embodiment described below exemplifies.
  • FIG. 1 It can also be seen that the electrode strips 6 and 7 are also to be regarded as formed as a pair anode. Reference is made to this twin anode technique DE 197 11 892 A1 the same applicant.
  • the illustrated electrode arrangement is only to be understood as a section of a possibly much larger electrode arrangement.
  • FIG. 1 illustrates that the electrode strips 1-6 and 7-12, respectively, a "unit cell" in the vertical direction in FIG. 1 define that can be repeated as often as you like.
  • FIG. 2 A cutaway view also shows FIG. 2 , to a second embodiment of the invention.
  • the twin anodes 6 and 7 are off FIG. 1 replaced by sinusoidally selected anodes 13 and 17.
  • the double cathodes are 3, 4, 9 and 10 made FIG. 1 in each case now simply, namely as electrode strips 15 and 19.
  • the unit cell corresponds to the electrode strip 15-19, which would result in pairs of cathodes when placed on each other, but which would form in FIG. 2 are combined to individual electrode strips 15 and 19 respectively.
  • the discharge distances correspond to the previous embodiment, wherein the discharge distance between the electrodes 13 and 14, 16 and 17 and 17 and 18 varies locally. Assuming that the in FIG. 2 shown structure is continued up and down, so a sinusoidal electrode in each case after both Has adjacent electrodes, so the upper and the lower half of a sinusoidal electrode 13 and 17 are assigned to each other neighbors. This means for example for electrode 17 that the "mountains” (in the sense of FIG. 2 ) define a discharge distance to the electrode strip 16 and the "valleys" to the electrode strip 18. These discharge distances vary between 3 and 4 mm.
  • the local variation of the discharge distance offers not only an alternative to the in FIG. 1 illustrated twin anode configuration, but is also suitable for a already mentioned in the introduction of the description conventional dimming technique. Reference is made to the application cited therein.
  • the electrode tracks were 0.6 mm wide. Per pulse 80 ⁇ J of energy were injected. By varying the dead times, it was possible to vary between full powers in the range of 8 W (excluding the large discharge distances) and 0.8 W (at 10 kHz) or 0.08 W (at 1 kHz). This corresponds to a dimming range of the luminous flux of 1: 500.
  • FIG. 3 shows a further embodiment, wherein in a schematic cross-sectional representation of an electrode assembly is shown in a tubular discharge lamp.
  • the Zündcousfunktion mentioned above can be represented here in two ways: on the one hand with the electrode strip 24 as a cathode, the electrode strip 23 as an intermediate electrode and the electrode strip 25 as an anode (in the sense of symbols +, 0 and - from the Figures 1 and 2 ). Further, with the electrode strip 22 as a cathode, the electrode strip 21 as an intermediate electrode and the electrode strip 25 as an anode.
  • Such a dimmable tube lamp is z. B. interesting as edge lamp in the flat screen backlighting.
  • FIG. 4 shows a further embodiment of an electrode pattern for a flat radiator lamp.
  • three equal sawtooth-like electrode tracks arranged relatively close together in parallel.
  • the two outer electrode tracks of each triplet arrangement or each mirror-image triad arrangement are connected to common outer terminal tracks 26 and 27 to electrode groups.
  • Each central electrode track, both of the three-way arrangements and the mirror-image three-way arrangements, is connected to a further outer connection track 28 to form a further electrode group.
  • the individual "saw teeth" are asymmetrical. They have a relatively long flat and a short steep ramp.
  • connection tracks 26 and 27 are connected as (instantaneous) cathode or anode (case I).
  • the connecting track 28 is connected in this case with no pole of an electrical supply source (potential-free or floating potential).
  • connection tracks 26 and 27 are connected together as a (instantaneous) cathode and the connection track 28 as an (instantaneous) anode (Case II).
  • the individual discharges burn exclusively between the respectively closest adjacent electrode tracks of each triplet arrangement, wherein the individual discharges each attach to the sawtooth tips and burn to the next adjacent central electrode track.
  • the switch over in a manner known per se, for example, electronically by means of relays or the like.
  • U s is the pulse peak voltage
  • f is the pulse repetition frequency
  • P is the average electrical power coupled into the flat radiator lamp.
  • the electrode configuration can also be operated in bipolar alternating pulse mode in the case of double-sided dielectric obstruction.
  • a variant of the representation in FIG. 4 may be provided between the three-arrays each having a substantially straight electrode track. This makes it possible by means of a suitable third control variant (case III) to realize a mean electrode or discharge distance.
  • FIG. 5 shows a detail, ie without outer connecting tracks, another embodiment of an electrode pattern according to the invention.
  • the electrode pattern is only to be understood as a section of a possibly much larger electrode arrangement.
  • This electrode pattern is opposite to that FIG. 4 the advantage that it manages with less electrode tracks and also has a good homogeneity of the luminance distribution, as will be explained below - the individual discharges with short or long distance burn at almost the same positions.
  • the spatial distribution of the discharge structure largely remains when switching to the respective alternative control variant, with only different overall luminance.
  • two electrode tracks (29, 30) each having a complex shape are arranged relatively close to one another. They serve in operation to produce a discharge structure (not shown) with relatively small strike distances. At a greater distance from this two-membered arrangement (29, 30) follows a mirror-image two-membered arrangement (31, 32), etc ..
  • the electrode webs (30, 31, 32, 29), which are adjacent to one another at the greater distance, are used during production a discharge structure (not shown) with relatively large impact widths.
  • FIG. 6 taken.
  • the schematic representation serves merely to clarify how the shapes of the electrode tracks (29-32) in FIG. 5 can be constructed.
  • the bottlenecks may also be arcuate instead of wedge-shaped.
  • the control properties of the discharge in the region of the bottleneck are "softer", similar to the arcs of the electrode tracks 13 and 17 in the FIG. 2 ,
  • each second electrode web is formed only sawtooth.
  • every other electrode web may also be straight or at least substantially straight. In any case, this reduces the number of bottlenecks within each two-tier arrangement and consequently the number of partial discharges during operation. This variant is therefore particularly suitable for very low luminance in dimming mode.
  • the flat lamp has two parallel glass plates (thickness: 2 mm, dimensions: 105 mm by 137 mm) as the main boundary walls.
  • On a base plate of the flat lamp is an electrode pattern, for example according to FIG. 4 or alternatively according to FIG. 5 or a variant applied as a metal screen print pattern.
  • the baseplate and frame are followed by a light-reflecting layer of Al 2 O 3 or TiO 2 . All inner surfaces have a three-band phosphor layer.
