Definitions
- the invention relates to an excimer radiator with a discharge space, the one under discharge conditions Contains excimer-forming, halogen-containing filling gas. Furthermore, the Invention, a method for producing a durable excimer lamp and a method to extend the life of such an excimer radiator and a device to carry out the latter procedure
- Excimer emitters are used to generate high-energy UV radiation.
- the excimer radiation is also known as silent electrical discharge. This is in one of Dielectrics limited discharge space in which the fill gas forming the excimers is included.
- An excimer radiator of the type specified is known from EP-A1 0 547 366.
- Excimer radiators described there are used as filler gases depending on the desired spectral composition
- various noble gases of the radiation for example argon, krypton or Xenon or noble gas mixtures are proposed, for example chlorine or a chlorine-containing one Contain compound from which one or more chlorine atoms are split off in the discharge become.
- An excimer radiator designed as a planar flat radiator is known from EP-A2 0 521 553.
- the discharge space contains a rare gas filling containing halogen, the partial pressure of the halogen is between 0.05% and 5% of the partial pressure of the noble gas.
- the known Excimer emitters are characterized by a high irradiance.
- the maximum adjustable UV irradiance is reduced within the first 300 hours of operation.
- the drop in UV irradiance is typically greater than 50% of the initial irradiance.
- EP-A1 607 960 An attempt to extend the life of such a radiator is in EP-A1 607 960 explained. It describes an excimer emitter, one with a suitable filling gas filled, gastight sealed discharge space. For the purpose of extending the lifespan The emitter is proposed to contain gaseous impurities in the filling gas to remove and provide a "getter" for this purpose, which is inside the discharge space or in Connection with this can be arranged. However, it has been shown that the removal of filling gas impurities is not sufficient for a significant increase in the service life.
- the present invention is therefore based on the object of an excimer radiator with a high Specify service life and a method for producing such an excimer lamp to provide.
- the invention is also based on the object of a method for increasing the lifespan of excimer lamps and a suitable device specify.
- the object is achieved on the basis of the excimer radiator mentioned at the outset in that the halogen content of the discharge space (16) per cm 2 of its inner surface is at least 1 ⁇ 10 -10 mol / cm 3 and at the same time as a function of the maximum power density of the radiator, expressed in the unit "watts per cm of radiator length" is set to a value in the range from 1 x 10 -7 mol / cm 3 to 1 x 10 -5 mol / cm 3 per unit of power density.
- the halogen loss can result from a reaction of the halogen with the inner surfaces of the discharge space are based.
- the boundary walls of the discharge space can, for example consist of quartz glass or of a ceramic.
- the surface reaction of the halogen can indeed be modified by a suitable modification of the discharge space Avoid interior surfaces.
- such measures are complex and expensive generated modifications are also often not sufficiently resistant to Discharge.
- applied protective layers can peel off.
- the saturation concentration is at a halogen content of at least 1 ⁇ 10 -10 mol / cm 3 per cm 2 of the inner surface.
- This halogen content can be measured in the filling gas before surface reactions with the halogen have taken place, for example before the emitter is started up.
- the halogen content in the discharge space can be determined if all halogen bound to or in the inner surface of the discharge space is added to the halogen content of the filling gas.
- the halogen content bound to or in the inner surface of the discharge space can be determined, for example, by releasing the halogen into the discharge space by means of a suitable temperature treatment.
- This halogen content can also be determined chemically or spectroscopically. It should be noted, however, that such halogen, which may additionally be present inside the material of the walls delimiting the discharge space, is not taken into account.
- synthetic quartz glass often contains a certain amount of chlorine due to the manufacturing process.
- the specified saturation concentration of halogens in the discharge space is permanently set, a decrease in the irradiance over time is avoided in whole or in part.
- a halogen concentration above the actually sufficient saturation concentration does not have a detrimental effect on the lifetime behavior. However, it affects the radiation characteristics of the radiator and reduces its maximum power density.
- the halogen concentration to be set continues to depend on the maximum power density of the radiator. On the other hand, it is therefore necessary to observe the further dimensioning rule that the halogen content in the discharge space, depending on the maximum power density of the emitter, expressed in the unit "watt per cm emitter length", to a value in the range from 1 x 10 -7 mol / cm 3 to 1 x 10 -5 mol / cm 3 per unit of power density is set.
- the specified relationship between the power density and the appropriate halogen content of the discharge space has up to a power density of approx. 200 W / cm Radiator length has been shown to be approximately linear. It can be assumed that this connection even at higher power densities, for example at power densities around 400 W / cm. Only the length of the actually illuminated is considered to be the spotlight length Spotlight.
- the specified saturation concentration corresponds approximately a mixing ratio of halogen: noble gas from 1:50 to 1: 500.
- These mixing ratios are only given as a guide for easier orientation. It will be in this Context expressly pointed out that not the mixing ratio, but the absolute halogen content, based on the size of the inner surface and the volume of the discharge space, and at the same time based on the maximum power density of the Excimer radiator, are crucial for the excimer radiator according to the invention. In doing so any buffer gases in the discharge space, which can also be noble gases, are not taken into account calmly.
- An excimer emitter in which the halogen content of the discharge space per cm 2 of its inner surface is in the range from 1 ⁇ 10 -10 mol / cm 3 to 1 ⁇ 10 -8 mol / cm 3 has proven particularly useful.
- the specified upper limit results from the efficiency of the radiator, which decreases as the halogen content increases.
- Halogen has a high electronegativity and usually has a lower probability of excitation compared to the noble gas. It therefore captures a relatively large number of electrons; the heater is difficult to ignite if the chlorine content is high.
- the filament density and consequently the halogen content in its atomic form increases.
- atomic halogen accumulates particularly easily on the boundary walls of the discharge space.
- the specified upper limit of the halogen concentration is therefore particularly relevant for excimer lamps with a high power density around 100 W per cm of lamp length, while with excimer lamps with a lower power density - without prejudice to the above-mentioned dimensioning rule with regard to the power density - this upper limit can be exceeded.
- An excimer radiator has a particularly long service life, in which the filling gas contains chlorine or a compound which releases chlorine under discharge conditions.
- a suitable chlorine-containing filling gas contains, for example, HCI with 2% Cl 2 and an inert gas, such as krypton, xenon or argon.
- An excimer radiator has proven to be particularly advantageous, in the case of which in the discharge space a reservoir containing the halogen is arranged, the concentration of the halogen in the reservoir is higher than that in the filling gas.
- the halogen in the halogen reservoir is from Filling gas of the discharge space separated. If the halogen content falls below a predetermined lower limit, the reservoir can be opened automatically or manually Halogen contained in the discharge space is released.
- the halogen content of the reservoir is so dimensioned that the concentration of the halogen in the release Discharge space is increased, for example, the target concentration by the release of halogen can be reached in the discharge space.
- a suitable halogen content of the reservoir is therefore simply due to the difference between the concentration at the lower limit and the target concentration and the volume of the discharge space.
- the reservoir has a relatively small volume compared to the volume of the discharge space.
- the Halogen concentration in the reservoir is therefore relatively high.
- the reservoir can, for example be designed in the form of a chamber made of quartz glass or a ceramic, which when reached the said lower concentration limit is broken.
- the lower concentration limit can be determined on the basis of intensity measurements of the excimer radiation.
- the above specified task based on the aforementioned method according to the invention solved in that the inner surfaces of the discharge space before filling the filling gas with a halogen-containing passivation gas.
- This passivation is a relatively simple modification to carry out the inner surface of the discharge space. You can, for example, on simple Way done by flushing the discharge space with the halogen.
- the invention according to the invention has proven to be particularly effective with regard to the extension of the service life Proven procedures using excimer emitters using chlorine or one under discharge conditions Chlorine releasing compound is used when used for passivation Chlorine is used.
- the halogen content of the passivation gas per cm 2 of the inner surface of the discharge space is advantageously at least 1 x 10 -10 mol / cm 3 , with the proviso that it is chosen to be at least as large as the halogen content in the filling gas.
- the term "halogen content” is understood to mean the concentration of the halogen based on the volume of the discharge space.
- the passivation can take place on walls of the discharge space made of quartz glass at an elevated temperature up to 1000 ° C; with ceramic walls even at higher temperatures.
- the above-mentioned object is achieved in that the discharge space with infrared radiation is applied or that halogen from one arranged in the discharge space Halogen reservoir is released.
- the infrared space creates the discharge space boundary walls heated. This is usually about Walls made of quartz glass. It was shown that the warming caused a pre-existing one Depletion of the fill gas on halogens can be reversed.
- the excimer radiator can be, for example, in one Oven can be introduced, or it is the radiation emitted by an infrared radiator exposed.
- halogen is from an im Discharge space arranged halogen reservoir released.
- concentration of the halogen in the reservoir is set higher than that in the filling gas. Due to the additional halogen A halogen loss in the discharge space can be compensated for in the reservoir. Does the fall Halogen content below a predetermined lower limit, the reservoir can automatically or can be opened manually, the halogen contained therein being released into the discharge space becomes.
- the formation of the halogen reservoir its halogen content and the Determination of the lower concentration limit is made to the above explanations.
- a method has proven to be particularly advantageous in which the discharge space is heated to a temperature in the range from 400 ° C. to 1000 ° C. by means of infrared rays.
- This temperature range applies to a discharge space with boundary walls made of quartz glass. If the boundary walls consist of a ceramic, such as Al 2 O 3 , temperatures above 1000 ° C are more favorable.
- Such a procedure has proven to be particularly effective in the case of chlorine-containing filling gas.
- the object stated above is achieved according to the invention in that that at least one infrared radiator is provided, which is arranged adjacent to the excimer radiator is such that the infrared radiation emanating from the infrared radiator forms the discharge space warmed up.
- every oven is also suitable as an infrared heater.
- the infrared radiator is advantageous provided with a reflector, which the infrared radiation on the discharge space directs and thereby an undesirable emission of infrared radiation in other directions prevented.
- the length of the infrared radiator corresponds or the total length of all infrared radiators roughly the length of the discharge space. Thereby the halogen is effectively released over the entire length of the discharge space.
- the infrared radiator advantageously runs or the infrared radiators run parallel to the discharge space of the excimer lamp.
- This embodiment of the device has the advantage that the release of the Halogen is reproducible from the inner surfaces delimiting the discharge space.
- Excimer emitters and infrared emitters can be switched on at the same time The above-mentioned time interval can also be 0.
- the operating hours are on the X axis and a relative irradiance is plotted on the Y axis.
- Figure 1 shows the life behavior of XeCl module radiators. These generate a power density of 25 W / cm lamp length.
- the filling pressure of the filling gas in the discharge space is 750 mbar.
- Argon as a buffer gas contributes about 300 mbar to this internal pressure.
- the discharge space in these emitters is formed by the space between two quartz glass tubes which run coaxially to one another.
- the outer diameter of the discharge space is 27 mm, the inner diameter is 16 mm and the length is 343 mm.
- the curve labeled with the reference number 1 represents the service life behavior of a previously available XeCl module radiator.
- the mixing ratio of xenon to chlorine is approximately 1000: 1.
- the absolute chlorine content in the discharge space is below 1 x 10 -10 mol / cm 3 per cm 2 of the inner surface of the discharge space; more precisely at about 3 x 10 -11 mol / cm 3 : the inside surface of the discharge space is about 470 cm 2 .
- the concentration information relates to the volume of the discharge space.
- the curve shape designated by reference number 2 represents the service life behavior in a XeCl module radiator in which the chlorine content of the discharge space is quintupled compared to the known excimer radiator described above.
- the mixing ratio of xenon to chlorine is therefore about 200: 1.
- the chlorine content is 1.5 x 10 -10 mol / cm 3 and cm 2 of the inner surface of the discharge space.
- the power density is approximately 30 watts per cm of illuminated spotlight length. Otherwise, the XeCl module radiators considered are identical.
- chlorine accumulates on the inner walls of the discharge space;
- the chlorine content in the filling gas therefore gradually decreases and can drop below the value of, for example, 5 ⁇ 10 -11 mol / cm 3 and cm 2 of the inner surface.
- the service life behavior of the XeCl module radiator according to the invention is characterized by only a small and in particular very slow decrease in the UVB irradiance out of time. After approx. 1000 hours of operation, the relative UVB irradiance only changes about 20% decreased. However, curve 2 does not yet show whether the irradiance amounts to an end value.
- a similar result of the service life behavior results from the creep diagrams of KrCl module radiators shown in FIG . These generate a power density of 25 W / cm lamp length.
- the filling pressure of the filling gas in the discharge space is 350 mbar.
- the discharge space in these emitters is also formed by the space between two quartz glass tubes which run coaxially to one another.
- the outer diameter of the discharge space is 27 mm, the inner diameter is 16 mm and the length is 343 mm.
- reference number 3 is assigned to a creep curve, as is usually the case with one KrCl module radiator is measured according to the prior art.
- the mixing ratio of Krypton to chlorine is about 1000: 1.
- the absolute chlorine content in this lamp is same as in the known XeCl module radiator described above.
- the UVC irradiance drops relatively sharply observe that after approx. 300 to 400 hours of operation in a low final value, which is below 10% of the original irradiance, flows out.
- Curves 4 and 5 are assigned to KrCl module radiators, which differ from one another only in the mixing ratio of the filling gas. These generate a power density of 25 W / cm lamp length. A buffer gas is not included.
- the initial krypton: chlorine mixing ratio is 100: 1
- the creep curve 5 50 1.
- the latter mixing ratio corresponds to a chlorine content of approx. 6 x 10 -10 mol / cm 3 per cm 2 of the inner surface of the discharge space.
- the inside surface of the discharge space is approximately 470 cm 2 .
- the life cycle behavior of KrCl excimer emitters with a relatively low power of 30 W is shown in the creep curves according to FIG .
- the illuminated spotlight length is 10 cm. It has been shown that the chlorine loss increases with increasing power density. This is based on the effect already mentioned, according to which the atomic chlorine content increases with increasing filament density, which in turn reacts on the inner walls of the discharge space and is thus removed from the filling gas.
- the creep curve labeled with the reference number 6 gives the typical life course with commercially available excimer emitters again, whereby after an initial sharp decrease in UVC irradiance after about 350 hours of operation an end value of Irradiance is achieved at a low level.
- the initial mixing ratio of chlorine: krypton in the filling gas is 1: 1000.
- the particularly good lifetime behavior of the emitter shown in FIG. 3 is the result of passivation of the inner surface of the discharge space before the filling gas is filled .
- the inventive one shows KrCl excimer lamps only show a slight decrease in UVC irradiance during the test time of approx. 2000 hours.
- the excimer radiator 11 consists of an outer quartz glass tube 12, which is covered on its outer surface with a metallic mesh 13, which forms the outer electrode of the excimer radiator 11 and an inner quartz glass tube 14, which is arranged coaxially with the outer quartz glass tube 12 and on the inner wall of which Metallic spiral 15 is present, which forms the inner electrode of the excimer lamp 11.
- the annular gap between the outer quartz glass tube 12 and the inner quartz glass tube 14 corresponds to the discharge space 16 of the excimer radiator 11.
- the volume of the discharge space 16 is approximately 470 cm 3 .
- the power density of the spotlight is 30 watts per cm of the illuminated spot length.
- a quartz glass capsule 17 filled with chlorine is arranged in the discharge space 16.
- the wall of the capsule 17 is scored and in this way provided with a predetermined breaking point 18.
- the chlorine content of the capsule 17 is adjusted so that after breaking the capsule 17, the chlorine content in the discharge space 16 is increased by 1 ⁇ 10 -11 mol / cm 3 and per cm 2 of the inner surface of the discharge space 16.
- a metal part 19 is embedded in the wall of the capsule 17 and from the discharge space 16 shielded.
- the metal part 19 together with the capsule 17 is in a by means of a magnet 20 held upper position.
