Definitions
- the invention is based on a high-pressure discharge lamp with a ceramic discharge vessel according to the preamble of claim 1. It can be high-pressure discharge lamps, as used in particular for general lighting.
- the invention describes an electrode system for HID alternating current lamps, consisting of a W electrode, which consists of a rotationally symmetrical body and is divided into two parts with different diameters, such as a feedthrough attached thereto, which is arranged in a capillary ,
- the invention reduces the dead volume in the capillary very reliably and with high accuracy.
- there is a welded joint between the electrode and the bushing This is brought to an uncritical temperature by the length of the electrode, which projects far into the capillary. This reduces the risk of the electrode breaking off or kinking due to temperature influences.
- a high-pressure discharge lamp with a ceramic discharge vessel in which two electrodes and a light-emitting filling are contained, wherein at the ends of the discharge vessel capillaries sit, in which passages are sealed, which are each connected to an electrode made of tungsten.
- the electrode is pin-shaped and made up of two parts of different diameter, wherein the first part with a given diameter D1 forms the electrode tip and the second part with a diameter D2 sits in the capillary, wherein the diameter D2 of the second part at least 108% of the diameter of the first part, the total length L of the electrode being divided between the first part with a part length L1 and the second part with a part length L2, that L2 is about 30 to 70% of the total length L, and the beginning of the maximum diameter D2 coincides with the beginning of the capillary or deviates from it by a maximum of 10% of the length L.
- the diameter D2 of the second part is at least 95% of the inner diameter ID of the capillary, so that the dead volume is minimized.
- the second part is connected to the passage through a weld. It is also recommended that the diameter of the bushing be at least 10% exactly the diameter of the second part.
- the transition between D1 and D2 can be made abruptly by means of a step, but it can also be beveled, so that a gradual transition arises.
- the diameter D2 should make up to a maximum of 150% of D1, otherwise there will be too much waste.
- Optimum thermal management can be achieved by providing additional thickening on the first part near the tip. These may be an integral head, or even a coil, which is pushed onto the first part. preferred is the integral head, since it can be easily made in one operation, which reduces the waste.
- the maximum diameter of the head is therefore the same as that of the second part.
- the heat capacity can be adjusted over the length of the head.
- the diameter of the head, D3, may be between D1 and D2.
- the electrode and the electrode system is used for high-pressure discharge lamps, the filling of which contains metal halides.
- the ratio of the diameters of the first and second parts of the electrode must now be set very precisely and adjusted in particular so that the second part is closely matched to the inner diameter of the capillary.
- the values should be between 1, 3 and 1, 6.
- a typical value is a factor of 1, 4.
- an electrode head which in particular by a coil, a sleeve or massive thickening, as known per se, can be realized. But he can also be a pin without thickening.
- the plasma-facing portion of the electrode requirements are different from the larger diameter of the rear second, the melting facing part.
- the electrode is preferably made of tungsten or similar refractory material, especially a high tungsten compound.
- the front the plasma-facing first part of the W electrode to dissipate just enough heat that the temperature of the electrode tip on the one hand is not so high that unnecessarily high evaporation of tungsten, on the other hand, the heat dissipation should not be so large that in the cathode phase (AC operation) sputtering occurs.
- AC operation cathode phase
- the optimum diameter of the rear part namely the melting of the facing shaft portion of the electrode
- other criteria apply.
- the optimum diameter is mainly due to the availability of the stem part with the cerium-, molybdenum-, Nb (Zr) - u./o. further conceivable Kapillar be arrangementsbaumaschineer determined in the direction Glasloteinschmelzung. These requirements set an optimum - A -
- the diameter of the second part It is determined by the condition that the ratio between capillary feedthrough and electrode shank portion is preferably between 0.5 and 1.0, including limits.
- Electrodes for discharge lamps according to the invention are made of high temperature resistant metal.
- Tungsten, molybdenum, tantalum, rhenium or alloys thereof are particularly suitable, but also carbides of these metals, in particular tantalum carbide (TaC).
- the electrodes are made of blanks of appropriate dimensions by turning, grinding, drilling, etching, etc. Particular preference is given to a charging process as described in DE 42 06 002.
- deformation work is additionally introduced by suitable manufacturing processes, such as rolling and hammering, in order to increase the structural stability of the electrode materials.
- the electrode materials used are now high-temperature-resistant metals, e.g. W, Ta, Mo, Re or their alloys, some of which are additionally doped in order to increase the microstructural stability of the materials.
- the doping for microstructure stabilization is carried out with elements such as e.g.
- one-piece electrodes in particular made of tungsten, are produced, wherein the complex contour may have a rear part as a second part, which is cylindrical, and a front part as a first part, which may have a head.
- the temperature at the junction is not more than 1500 K, more preferably not more than 1300 K.
- the result is then a kinking of the W electrode at the connection point, which is usually a weld. If the W electrode touches the inner wall of the capillary, cracks in the capillary occur, through which the filling escapes from the discharge vessel. This shortens the life and the lamp goes out.
- the different requirements for the two parts of the W electrode are now best met by the fact that the electrode is integral and that the Wo- rammaterial in the front first part of the W electrode is removed. This is best done by mechanical, chemical or thermo-mechanical methods such as laser ablation.
- the present application also relates to a high-pressure discharge lamp with such an electrode, in particular with metal halide filling, as is known from the type already known from EP-A 1 056 115.
- the diameter of the second part should therefore be adapted to the inner diameter of the capillary as well as possible and so fill the dead volume.
- the end of the electrode can be laid as far back as possible into the capillary, up to 70% of the total length L of the electrode.

- the end 6 of the discharge vessel and the stopper capillary 12 are, for example, directly sintered together.
- At the feedthrough sits an electrode 15 on the discharge side.

- a two-part electrode shaft 16 made of tungsten extends within the capillary tube 12 towards the discharge volume and has a helix 17 which is pushed onto the discharge-side end.
- the filling of the discharge vessel is in addition to an inert ignition gas, such as argon, from mercury and additives to metal halides. It is also possible, for example, the use of a metal halide filling without mercury, wherein As ignition gas, for example xenon and in particular a high pressure, well above 1, 3 bar, can be selected.

- FIG. 4 shows an electrode 30 in which the head is a separate coil 31. It is further shown that between the first part 25 and the second part 26, a slope 33 is used as a transition.
- the electrode system 35 is shown in detail in the plug 36.
- a passage 9 is a pin, for example, as shown in Figure 6, a two-piece pin, the first part near discharge 38 is a cermet of Mo and Al 2 O 3 , and the second part 39 of niobium or NbZr or MoV is.
- the lead-through may also be partially encased by a helix.
- the second part 26 of the electrode has approximately the same diameter as the pin and is welded thereto. This is followed by the discharge side of the first part 25, whose diameter is significantly smaller, both parts are made of one piece.
