Definitions
- the invention relates to a dielectric barrier discharge lamp and a Lighting system with such a lamp and an electrical Power Device.
- dielectric barrier discharge lamp encompasses sources electromagnetic radiation based on dielectrically disabled Gas discharges.
- the spectrum of the radiation emitted by the gas discharge can both the visible area and the UV (ultraviolet) / VUV (vacuum ultraviolet) range and the IR (infrared) range include.
- a phosphor layer can also be used for conversion be provided invisible in visible radiation (light).
- the discharge vessel is usually filled with an inert gas, for example xenon, or a gas mixture.
- an inert gas for example xenon, or a gas mixture.
- excimers are formed during the gas discharge, which is preferably operated by means of a pulsed operating method described in US Pat. No. 5,604,410.
- Excimers are excited molecules, such as Xe 2 *, which emit electromagnetic radiation when they return to the normally unbound ground state. In the case of Xe 2 *, the maximum of the molecular band radiation is approximately 172 nm.
- a dielectric barrier discharge lamp necessarily sets at least a so-called dielectric barrier electrode ahead.
- a dielectric disabled electrode is opposite the inside of the discharge vessel separated by means of a dielectric barrier.
- This dielectric barrier can, for example, as a dielectric layer covering the electrode be carried out, or it is formed by the discharge vessel of the lamp itself, namely if the electrode is on the outer wall of the discharge vessel is arranged.
- a time-varying voltage between the electrodes is required, for example a sinusoidal AC voltage or pulsed voltage as disclosed in US-A 5,604,410.
- US-A 5,432,398 is a high power radiator based on the dielectric disabled discharge in the form of a coaxial double tube arrangement disclosed.
- An outer electrode in the form of a wire mesh extends over the entire circumference of the outer quartz tube.
- a helical inner electrode is inserted into the quartz tube.
- the Inside of the inner quartz tube is filled with a coolant, which is a has a high dielectric constant and not only for cooling but also for coupling serves the inner electrode to the inner quartz tube.
- the discharge space are formed when one is in contact AC voltage between the electrodes a variety of discharge channels.
- the object of the present invention is to provide a dielectric barrier To provide a barrier discharge lamp according to the preamble of claim 1, which shows an improved ignition behavior.
- the dielectric barrier discharge lamp according to the invention has at least an electrically conductive agent to support the ignition of the dielectric barrier discharge on the discharge vessel wall is arranged and with respect to the longitudinal axis only over a partial area the discharge vessel wall extends.
- the dielectric barrier discharge lamp internal electrodes because this embodiment has proven to be particularly efficient according to US Pat. No. 6,097,155.
- the dielectric barrier electrodes by on the inside of the Wall of the discharge vessel arranged and with a dielectric Layer covered elongated electrodes realized.
- the electrically conductive agent is arranged on the outside of the wall of the discharge vessel.
- This embodiment has the additional advantage that the average of Outside, i.e. after the completion of the discharge vessel, applied can be.
- Suitable as an electrically conductive agent among others a ring or part of a ring, especially made of metal, which can also be retrofitted on the elongated, in particular circular discharge vessel can be plugged on.
- a differently shaped surface configuration of the agent suitable for example a rectangular, round or oval shaped metal sheet, under certain circumstances, however, further precautions for fastening of the agent are to be hit on the wall of the discharge vessel. This can be avoided if the agent is coated with an appropriate conductive coating, For example, a metallic solder layer is realized.
- the width of the means along the longitudinal axis of the discharge vessel is typically between about 1 mm and a few 10 mm, in particular between 3 mm and 15 mm. It has been shown that this is reliable on the one hand Ignition is usually sufficient and on the other hand that of the Lamp emitted light is still relatively little shadowed.
- the means is preferably arranged at one end of the discharge vessel. It has proven to be advantageous if the means an end to the elongated Electrodes overlap. An overlap of a few mm, in particular approx. 1 mm is already sufficient. However, the mean can be the elongated Electrodes also overlap over their entire width.
- the lamp at least has at one end on a base, the means integrated in the base is.
- the electrically conductive agent is also on floating electrical It has proven to be potential if the remedy with Earth potential, preferably with the ground potential of the lamp supplying Voltage source is connected. Has the connection to ground potential the advantage that there is a defined tension between means and Adjust electrodes.
- the electrodes are used to complete a complete lighting system the dielectric barrier discharge lamp according to the invention connected to the associated poles of a voltage source.
- the mean is associated with constant potential, with respect to the time-varying Voltage at the poles of the voltage source.
- the voltage source is preferably designed such that they have a pulse voltage sequence at their poles can provide. For further details, see EP-A 0 927 506.
- the voltage source is particularly preferred designed that the voltage source with respect to its ground potential can provide symmetrical pulse voltage sequence, the mean is connected to the ground potential.
- the use of a symmetrical One of the advantages of tension here is that there are no undesirable ones capacitive currents flow through the mean through the ground line.
- FIG. 1 shows a rod-shaped fluorescent lamp 1.
- the lamp 1 consists of essentially from a tubular discharge vessel 2 made of soda-lime glass with a circular cross-section and two strip-shaped electrodes 3 (the second electrode is covered and therefore not visible), the parallel to the pipe longitudinal axis and diametrically arranged to each other on the inside the wall of the discharge vessel 2 are applied.
- Each of the inner electrodes 3 is covered with a dielectric barrier 4 made of glass solder.
- the Inside of the wall of the discharge vessel with a layer of phosphor covered (not shown for illustrative reasons).
- a first end of the discharge vessel 2 is by means of a blunt fusion 5 closed.
- the second end of the discharge vessel 2 is by means of a plate-shaped closure element (not recognizable in this representation) closed.
- the edge of the plate-shaped closure element with a Narrowing 7 of the discharge vessel 2 fused.
- a metal ring 8 of width B 5 mm - viewed in the direction of the longitudinal axis of the discharge vessel 2 - arranged on the outside of the wall of the discharge vessel 2.
- the Metal ring 8 shown in Figure 1 transparently.
- the lamp 1 is for a pulsed mode of operation according to that already mentioned US-A 5,604,410.
- the voltage source is designed to have one on both of its poles To provide ground potential symmetrical pulse voltage sequence.
- the metal ring 8 is connected to the connection 9 Ground potential of the voltage source connected. This makes the Metal ring 8 as a means of improving the ignition behavior, whereby significantly lower voltages to ignite the lamp after a long time Business breaks are required than without a ring.
- FIG. 2 shows a variant of the lamp from FIG. 1.
- the variant in figure 1 differs in that the metal ring 8 has the second end of the discharge vessel 2 and pushed over the constriction 7 (hidden here and therefore not visible) is arranged.
- connection 9 is common to the second end of the lamp with the supply lines (not shown) for the power supply lines 6 the electrodes 3 can be led to the voltage source.
- the probability for the beginning mentioned undesirable occurrence of the filament-like partial discharge is particularly significantly reduced.
- the metal ring 8 has the constriction 7 in each Case a favorable influence on the electrical field in the area of the implementation the power supply lines 6 into the interior of the discharge vessel 2.
- the lamp has a base (not shown) provided, in which the metal ring is integrated.
