Definitions
- the invention relates to a method for producing a discharge lamp according to the preamble of claim 1.
- They are in particular Hochdruckdruckladlamlam ⁇ pen with quartz glass vessel and metal halide.
- An object of the present invention is to provide a method with which the skew ⁇ position of electrodes can be prevented without additional components in a simple manner.
- Electrode systems containing films are usually inserted in the middle of the longitudinal axis of the discharge vessel in the ends. They can be centered in the PRinip by means of a holding system, a clip or suitably shaped power supply. However, they can also be fixed and directed in the discharge vessel of quartz glass by a suitable geometric shaping of the fusing region of the ends of the discharge vessel in its X-direction, defined here as the broad side of the film of an electrode system, and the Y-direction, defined here as the narrow side of the film hold.
- the nubs of the end is a special form of squeezing, in which the tubular end is not closed. Such a technique is only intended for provisional fixing and fixing of the electrode shaft, while still provisionally evacuation, or gas exchange on the bottleneck thus created to the interior of the discharge vessel remains possible.
- the manufacturing process is such that initially a piston tube with open ends and externally held
- Electrode systems is used in a melter.
- the flask is then flushed through the open ends.
- a tubular end is heated Minim ⁇ least two points which lie on a circumference of the tube to.
- the shaft of the electrode is fixed by the Noppungsrea, at one end.
- the first meltdown is completed.
- a filling may be introduced fene of ⁇ end into the discharge vessel through the one-sided. Since ⁇ according to the second embossment the melting is carried out and subsequently ⁇ PHd completed, so that the film is com pletely ⁇ encased in quartz glass.
- the wall thickness of the tubular end can be in the übli ⁇ chen range of typically 1 to 3 mm.
- the electrode systems are supported by the "finger of Nop ⁇ pen at the stem ends to the process of melting down. During heating, glass transition temperatures of the order of 2000 ° C are reached at the points of the nip.
- the Einnoppung is comparable to a similar process for permanently fixing the filament of halogen incandescent lamp, as previously known from EP 446 458.
- the pimple area can later be over- melted to complete the meltdown.
- the dimpled area during a ⁇ melt process quasi the function of a "thermal brake". Because of the already existing here thermal contact between the film and glass melting process is terminated prematurely so that usually remain slight dents in the area of the seal. This so to speak, two-stage melting operation also has the effect that the final discharge vessel has a higher mechanical strength than wetting processes in a single stage Einschmel- because remain not so large thermal Spannun ⁇ gen.
- two opposing studs or even three evenly distributed around the circumference of the tube knobs are used.
- FIG. 1 shows a high-pressure discharge lamp
- Figure 2 shows a discharge vessel with stocked
- FIG. 3 shows a detail of the end of the piston with the electrode system (FIG. 3 a) directed therefrom and the associated section (FIG. 3 b);
- FIG 4 shows the same detail after the Noppungsvorgang
- FIG. 1 shows a metal halide lamp 1 which is sealed by melts 2. It is a 150 W lamp with a bulbous discharge vessel 3.
- the melts 2 have a diameter of about 5 mm.
- an electrode system 14 is fixed, with a power supply 5, a film 4 and a pin-like electrode, with a shaft 10 and egg ⁇ nem head part 11, which projects into the discharge volume.
- a pipe piece 6 integrally.
- a base part 7 is integrated.
- the discharge vessel is surrounded by an outer bulb 8, which is designed substantially cylindrical. He narrows himself to the pipe section 6 out.
- the filling is a common metal halide filling for general lighting as known per se.
- In the extension of the tubular end of the base 7 is supported, which is in communication with the external power supply 5.
- Such a compact lamp achieves a lifetime of at least 6000 hours, in particular even more than 12000 hours, with optimum design despite high load.
- FIG. 2 shows such a discharge vessel 3 is shown schemati ⁇ default, whereby the two ends 15 are still untreated and are formed as tubular parts. In the tubular ends, two electrode systems 14 are used. In this case, the thickness of the front part of the tube-like end can be reduced in preparation for the melting.
- Figure 3 is shown as a detail of an end 15 (Figure 3a) and the associated cross section ( Figure 3b), in which En ⁇ de 15 still enough space for pumping and rinsing remains.
- Such a component of the discharge vessel and the electrode system is in sets ⁇ a Einschmelzmaschine. Thereafter, the still open piston is flushed over the ends, as is known per se, usually with inert gas. Subsequently, at both or initially only at one end 15 in the amount of the later Einschmelzrios the tubular end is heated at two opposite points.
- FIG. 4 shows that, as described in EP 446458, two fingers 20 now center the electrode shaft 10 (FIG. 4 a).
- FIG. 4b shows that here again enough space for further pumping and rinsing as well as filling remains in the pipe 15. ,
- an outer bulb 8 can be slipped over the discharge vessel as shown in FIG. Details of the preparation for this purpose are described for example in DE-A 103 25 554.
- a method according to claim 1 characterized in that two fingers are used per shaft.
- a method according to claim 4 characterized in that after filling optionally an electrode system is inserted into the second still open end, and that the second open end is closed in a manner analogous to the first end.
