Definitions
- the invention relates to a melting film and associated lamp with this film according to the preamble of claim 1.
- These are in particular Molybdenum foils, which are used for bruises like those used for sealing of incandescent lamps and discharge lamps are common.
- US-A 5 021 711 already includes a sealing film and associated lamp known this slide. To be better protected against oxidation, the film is included a protective layer of Al, Cr, Si, Ti or Ta. The thickness is 5 to 100 nm.
- a similar technique is known from DE-A 30 06 846, in which the same
- layers of Ta, Nb, V, Cr, Ti, Y, La, Hf or Sc can be used.
- the layer thickness is 10 to 200 nm.
- the oxidation of the foil-pin connections is not responsible for the failure of the foil seal, but the attack of the molybdenum foil by the corrosive filling components (e.g. metal halides) or filling gases.
- the molybdenum foil has previously been sandblasted, which leads to an improvement in the glass-metal connection.
- sandblasting leads to high rejects in resistance welding, since non-conductive Al 2 O 3 particles remain on the Mo foil surface.
- the wear of the resistance welding electrodes increases very much. In the case of sandblasted foils, it is necessary to replace the electrode after only approx. 70 welds (compared to an exchange interval of approx. 1000 welds with untreated foil), so that the electrodes have to be changed frequently.
- the molybdenum foil is partially or preferably on all sides with pure ruthenium or a compound containing ruthenium coated.
- Pure ruthenium and a molybdenum-ruthenium alloy are particularly suitable with eutectic composition.
- the layer thicknesses of the ruthenium-containing layer are preferably in the range of 0.02 to 1.0 ⁇ m. In a particularly preferred embodiment, the layer thickness is at 0.02 to 0.09 ⁇ m.
- the coating can be carried out by known coating methods, preferably by sputtering.
- molybdenum foils coated with ruthenium or ruthenium alloys are very easy to weld, in contrast to molybdenum foils with chrome, silicon, aluminum or similar are coated.
- the oxidation resistance of the pin-film welded joints by coating the power supplies with the same or similar coating materials that can be used for the film, elevated.
- the electric lamps according to the invention have a lamp vessel Quartz glass or hard glass, which is provided with molybdenum foil feedthroughs Are part of at least one pinch seal of the lamp vessel. In the at least one pinch seal, at least one molybdenum foil is squeezed in a gas-tight manner. According to the invention, the molybdenum foil or the molybdenum foils are included Provide ruthenium-containing coating.
- ruthenium pure or as an alloy
- filigree power supplies possibly designed as coils
- a brazing process can now be carried out are (preferably using a eutectic MoRu alloy), for the relatively low temperatures are sufficient (typically around 360 ° C less than at pure Ru). Instead of around 2300 ° C only temperatures around 1900 to 2000 are reached ° C reached.
- the inner power supply is preferably uncoiled and has a diameter from 10 to 100 ⁇ m, in particular 10 to 50 ⁇ m.
- the inner power supply simply coiled and has an outer diameter of 20 to 150 ⁇ m, in particular 20 to 80 ⁇ m.
- a method of establishing an electrically conductive connection between a Foil made of molybdenum and a metal wire, in particular with a diameter between 10 and 100 ⁇ m, is characterized in that the film contains a ruthenium Coating in the area of the wire contact surface is.
- the wire is made in particular of tungsten.
- the metal wire can be simply coiled and thus form a wrap.
- the outer diameter of the winding be between 20 and 80 ⁇ m.
- the invention is a high-pressure discharge lamp with an electrical Power consumption of approx. 24000 W.
- This lamp has a quartz glass Existing discharge vessel 1.
- the discharge vessel 1 has a discharge space 2 and two on opposite sides of the discharge space 2 arranged, cylindrical piston shafts 3, of which only in the figure one cut out and cut is shown.
- Two electrodes 4 made of tungsten each extend from the discharge space 2 into one of the bulb shafts 3 and are soldered there with a circular disk-shaped molybdenum disk 7.
- Four molybdenum foils 5 are welded to the molybdenum disk 7, which are uniform are arranged along the outer surface of a hollow quartz glass rod 8.
- the hollow quartz glass rod 8 was together with the molybdenum foils 5 inside of the hollow piston skirt 3 introduced.
- the molybdenum foils 5 form with the Quartz glass of the piston skirt 3 and the quartz glass of the hollow quartz glass rod 8 a gas-tight seal.
- the molybdenum foils melted into the quartz glass 5 have a coating 6 of 75 nm ruthenium.
- the electrode 4 is in the area of the piston skirt 3 with a molybdenum foil 10 wrapped around it, but not in Quartz glass is melted down.
- the embodiment of the invention shown in FIG. 2 is around a single-ended high-pressure discharge lamp.
- This lamp has a Discharged discharge vessel 9 made of quartz glass, in which an ionizable Filling comprising corrosive metal halides, gas-tight included is.
- Two electrodes 22, 23 are arranged within the discharge vessel 9 each via an embedded in the pinch seal of the discharge vessel 9 Molybdenum foil 24, 25 each with one protruding from the discharge vessel 9
- Power supply 26, 27 are electrically connected.
- the discharge vessel 9 is, at a short distance, completely gas-tight from a pinched on one side sealed envelope piston 28 surrounded.
- the envelope piston 28 is made of quartz glass, which is doped with about 0.5 weight percent cerium.
- a one-sided squeezed and Outer bulb 13 which is capped on one side, encloses the envelope bulb 28 in a gas-tight manner.
- the Outer bulb 13 is evacuated and also consists of approximately 0.5 percent by weight Cerium-doped quartz glass.
- Power supply lines 11, 12 are in each case in the pinch seal of the outer bulb 13 embedded molybdenum foil 14, 15 each with one from the outer bulb 13 outstanding power supply 16, 17 electrically connected. From the outer bulb 13 lead leads 16, 17 are out with the socket 18 protruding contact pins 19, 20 in electrical contact.
- Molybdenum foils used in this embodiment are all eutectic Mo-Ru alloy coated, the thickness of which is 500 nm.
- the composition is: molybdenum 43% by weight, ruthenium 57% by weight (preferably at least 40%, advantageously more than 50% ruthenium).
- the power supply lines 26, 12 and 17 are coated with a Mo-Ru alloy.
- the exemplary embodiment in FIG. 3 is a halogen incandescent lamp 35 (12V at 100 W power) with a lamp bulb 36 made of quartz glass Is sealed gas-tight with the help of a pinch seal 37.
- a pinch seal 37 In the press seal of the lamp bulb, two molybdenum foils 38 are embedded. Inside the lamp bulb there is a double coiled filament 39, the simple coiled ends act as inner power supply 40.
- the internal power supplies are each with one of the molybdenum foil embedded in the press seal 38 welded.
- Two external power leads protrude from the pinch seal 37 34, which are each connected to one of the two molybdenum foils.
- the two molybdenum foils embedded in the press seal are on one side on the Side on which the power supply 40 is attached with a eutectic Mo-Ru alloy Coated 90 nm thick.
- the spiral end 40 consists of 15 ⁇ m thick tungsten wire that is simply coiled is. Its outside diameter is 55 ⁇ m.
- the spiral end and the foil are connected to each other by a brazing process.
- the particular advantage is that previously a powder layer (resistance to coarse molybdenum Grain) had to be used, into which the winding was pressed. At, Continuity of the welding process resulted in several shunts the inhomogeneous powder layer. This led to high committee and limited the lower limit of the outer diameter of the single-spiral power supply to about 80 microns, while according to the invention also corresponding outer diameter can be processed between 20 and 60 ⁇ m.
- the ruthenium coating therefore enables improved connection technology between foil and power supply, this principle .both for the inner as the external power supply also applies. in general, however, are the inner ones Power supplies more critical. Therefore, the ruthenium coating can be on one side the film only in the vicinity of the contact surface of the power supply.
