Definitions
- the invention relates to a melting film and associated lamp with this film according to the preamble of claim 1. It is in particular Molybdenum foils, which are used for bruises like those used for sealing of incandescent lamps and discharge lamps are common.
- 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 Purpose layers made of Ta, Nb, V, Cr, Ti, Y, La, Hf or Sc are 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 corrosive filling components (e.g. metal halides) or filling gases on the molybdenum foil.
- 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.
- a molybdenum foil is preferably used for both parts.
- One or both Parts are specifically made with pure ruthenium, rhenium or chromium or a compound or alloy containing ruthenium, rhenium or chromium, coated.
- Pure ruthenium is particularly suitable as a coating material (Ru), rhenium (Re) or chromium (Cr) as well as a molybdenum-ruthenium alloy with eutectic composition.
- Ru does not only convey one reliable glass-metal connection, so that good adhesion of both components and thus a good seal is achieved, but also a simple joint connection when welding or soldering; it is also halogen-resistant and inert with regard to any contact with the filling.
- the first film is specific for the secure welding of the external power supply (typically pins made of molybdenum) and for safe oxidation protection designed. It is at least in the area of the connection between the power supply and film on both sides with an oxidation preventing or at least reducing Provide coating with a layer thickness of at least 800 nm. For this Foil are suitable for all three materials, however, the best results achieved with ruthenium.
- the second one, inside with respect to the piston volume The film is designed as a sealing section. It is not at all or one-sided with one thin coating ( ⁇ 120 nm), which ensures that the Spiral ends or internal power supplies guaranteed.
- ruthenium pure or as an alloy, especially Mo-Ru alloy
- the thickness of the layer which consists of at least one of the materials rhenium, chromium or ruthenium, is preferably in the range of 1.5 to 3 microns for the two-sided coated welding film.
- the layer thickness for the sealing film coated on one side is in the range of at least 20 nm for the case that the welding foil is coated with Ru.
- the use of Cr and / or Re for the welding foil means that the sealing foil can be coated be used or especially coated Ru for their coating become.
- the use of a eutectic is preferred for the sealing film Mo-Ru alloy and a layer thickness in the range from 40 to 80 nm.
- the two foils are welded together (especially resistance or laser welding).
- the coating can be carried out by known coating methods, preferably by sputtering. In the case of chrome also galvanic.
- 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 is squeezed in a gas-tight manner at least one molybdenum foil.
- the exemplary embodiment in FIG. 1 is a halogen incandescent lamp 1 (12V at 100 W power) with a lamp bulb 2 made of quartz glass, which with the help a pinch seal 3 is sealed gas-tight.
- a pinch seal 3 In the pinch seal of the Two molybdenum foil stacks 4 are embedded in the lamp bulb. Inside the lamp bulb there is a double coiled filament 5, the simple coiled ends act as internal power supply lines 6.
- the internal power supplies are each with one of the molybdenum foil stacks embedded in the press seal 7 welded. Two external power leads protrude from the pinch seal 3 8 out, each connected to one of the two molybdenum foil stacks are.
- the two molybdenum foil stacks 4 embedded in the pinch seal are made each made of two films 10, 11.
- the inner sealing film 11 is on one side on the side which is attached to the inner power supply 6, with a eutectic Mo-Ru alloy 60 nm thick coated.
- the outer welding film 10 is pure on both sides Ru coated, the layer thickness is 2.5 ⁇ m. Both foils are the same width.
- the outer welding foil is clean on both sides Cr or Re coated with a thickness of 2.5 ⁇ m.
- the inner sealing film 11 is either not at all or one-sided on the side on which the inner power supply 6 attached, coated with a eutectic Mo-Ru alloy 60 nm thick.
- the two foils 10, 11 overlap to approximately 10 to 40%, preferably 15 to 30% %, the area of a broad side of the welding foil 10 and are in this stacking area welded together.
- the welding film 10 is located, the total area of which is smaller than that of the sealing film, on the, possibly larger, sealing film 11 on.
- An embodiment is preferred in which both foils 10, 11 are of equal width because the orientation and adjustment of the foils is made easier.
- the overlap of both foils is shown in Figure 1 by the dashed end of the bottom Seal film 11 identified.
- the coil end which acts as an internal power supply 6, consists of 15 microns thick Tungsten wire that is simply coiled. Its outside diameter is 55 ⁇ m.
- the coil end and the sealing film 11 are connected to one another by a brazing process.
- the technology of differentiated ruthenium coating does not only make it possible an improved connection between film and power supply, but also a reliable connection of the two films of the stack.
- the frame can be manufactured in such a way that initially two Welding foils 10 (Figure 2a) with a U-shaped wire bracket 15, which as Forerunner for the two external power supplies is used, welded.
- the Wire bracket 15 is on the top of the welding foils 10 coated on both sides attached.
- this frame part is placed on two sealing foils coated on one side 11 placed, with a slight overlap of about 15% of the area of Welding foil 10, wherein the coated sides of the two foils touch.
- the two films in the stack are of different widths and lengths.
- the coating is not shown separately.
- the overlap zone is welded.
- the weld is represented symbolically as reference number 16 (FIG. 2b).
- a frame part, consisting of internal power supply lines 6 and luminous element, on the free End of the welding foils 11 placed and soldered (Figure 2c).
