Definitions
- the invention relates to a method for mounting a base for a discharge lamp according to the preamble of patent claims 1 and 6, respectively, and to a discharge lamp according to the preamble of patent claim 9.
- a method of mounting a pedestal for a discharge lamp according to the preamble of claims 1 and 6, respectively, is well known. Following preparation of the unloading with manure vessel placed therein electrodes and a soldering an electrode support bar, so that it can serve as outdoor facilities located in the circuit to the discharge electrodes ⁇ vessel by z. B. protrudes from an end region of the discharge vessel, the discharge vessel is provided in capless form. Now a So ⁇ ckelhülse can not be easily placed on the discharge vessel, because the shape of the end portion of the discharge ⁇ charge vessel is not perfectly to the base sleeve ⁇ passable.
- a base sleeve on the end region material is applied to this, which serves as a buffer material between the base shell and Entladungsge ⁇ vessel.
- the material should be soft.
- putty graphite tape is used for this purpose, which is wound in several layers on the typically ⁇ cylindrically shaped end. It may also be applied a suitable ceramic mate rial ⁇ , especially listed on the end portion be wrapped.
- the base sleeve is, after it has been placed on the end region with the material held by a clamping ring at the end. In this case, the base sleeve transmits the force exerted on it by the clamping ring over the material applied to the end region onto the discharge vessel.
- the material up to the end ⁇ brought has an important function, that of intercepting these forces. If the forces are too strong, the discharge vessel can be damaged, eg. B. if it is formed as often from glass. Even with discharge ⁇ vessels made of quartz glass tensions that have led to cracks and thus permanent damage may occur. To avoid such damage must be sensitive to ensure that the material is applied with a sufficient and on the other hand, not excessive amount on the Endbe ⁇ rich.
- individual deviate ⁇ tions must take into account when forming the discharge vessels. In the manufacturing process, it may be that the cylindrically shaped end region once a slightly smaller and another time has a slightly larger diameter. There may also be deviations from the perfect cylinder shape in that the end region has a rather oval cross-section.
- the object of the present invention is to determine readiness a method of assembling a socket for a discharge lamp ⁇ according to the preamble of claim 1, wherein the automation is possible.
- such a clamping ring is thus placed on the base sleeve, which means comprises at least ⁇ a bead, a substantially rinnenför--shaped material extension.
- a clamping ring with a bead of the clamping ring is flexible, so it can be adapted in its form and in its inner diameter.
- With a suitable design of such a clamping ring can be compensated for fluctuations in the shape of the discharge vessel in the base area, even if ⁇ example, when the said material is applied in an automated process on the end portion of the force applied to the end portion of material is not perfectly matched to the individual characteristics of the Endbe ⁇ realm of the discharge vessel.
- the clamping ring can even be designed so that the force exerted on the discharge vessel is always the same, even if the discharge vessel varies in shape within certain limits.
- a clamping ring with a single bead which preferably extends axially over the clamping ring, is sufficient for carrying out the invention.
- Axial is in this case based on an axis which is perpendicular to a plane in which the clamping ring has a circular cross-section, z. B. is perpendicular to the center of the circle in a circular ⁇ shaped cross-section.
- the clamping ring used in the method according to the invention has a series of such axially extending beads around its circumference.
- graphite ring be ⁇ riding is used as graphite ring be ⁇ riding provided, and this graphite ring is simply striped the end area.
- the discharge lamp can be made automatically. Because graphite is a very soft material, the graphite ring can absorb forces exerted by the clamping ring.
- the ability of the graphite ⁇ rings to compensate for individual variations in the shape of a Entla ⁇ -making vessel in the end region of the desired shape, thereby can be conveyed, is that the graphite phitring slotted design (particularly with axially ver convinceddem slot), thereby at different extent of the end region particularly well anpas ⁇ sen can, and the supplied graphite ring can also have at least one bead, which bead then has the same effect as the bead of the clamping ring in the first aspect of the invention, namely the effect that through the graphite ring on it forces acting out so ⁇ equalized and distributed such that substantially always the same force on the discharge vessel acts, even if the discharge vessel deviating within certain limits from a basic or nominal shape.
- By the bead on the graphite ring a good power transmission as for the adhesion is useful guaranteed.
- the two aspects according to the invention are combined with one another in a preferred embodiment, that is, the graphite ring is placed on the end region and a clamping ring with a bead is used.
- the discharge lamp according to the invention has in a basic ⁇ construction according to the preamble of claim 9, as it is known per se, the salient feature that the base sleeve frictionally with the Entladungsge- connected. By the force fit is guaranteed slightest ⁇ tet that always the same force is applied to the discharge vessel, even if its shape deviates from a basic form so that damage of the discharge vessel can be avoided.
- the discharge lamp according to the invention can be provided with the two methods according to the invention.
- the power circuit can be provided that on the base sleeve a clamping ring is seated, wherein at least one bead (preferably a series of axially extending corrugations over its circumference thereof), and the power circuit can also be prepared ⁇ to that between the base sleeve and the end portion of a graphite ring is arranged, and this is preferred ge ⁇ slits, and additionally or alternatively preferably includes at least one bead.
- at least one bead preferably a series of axially extending corrugations over its circumference thereof
- FIG. 1A shows the construction of a high-pressure discharge lamp during its production at different steps of a preferred embodiment of the method according to the invention
- Fig. 3 is a base sleeve used in the inventive method (half-side sectional view) and 4 shows a clamping ring used in the method according to the invention
- Fig. 5a u. 5b a clamping ring with a bead in (right. Front view
- FIGS. 5a, 5b shows the graphical representation of the measured values for the clamping ring from FIGS. 5a, 5b in comparison with a standard clamping ring.
- the inventive method is based on a under construction be ⁇ -sensitive high-pressure discharge lamp in which in Fig. IA overall showed state.
- This state is achieved after generating a discharge vessel 10 made of glass or quartz glass with two adjacent on opposite sides of cylindrical shafts 12 that have been soldered to the glass vessel 10 located in the electrodes 14 and 16 each electrode holding rods 18 and 20 to be used as an external connection for the To serve electrodes, so as to provide a Maisierillonkeit with the electrodes for Verf ⁇ supply.
- the electrode holding bars 18 and 20 are out of the cylindrical shafts 12, that is, the two end portions of the discharge vessel 10. It is now a base are provided by the ⁇ sen, the high pressure discharge lamp into a socket insertion ⁇ bar.
- a graphite ring 22 shown in perspective in FIG. 2 is plugged onto one of the shafts 12.
- the graphite ring has a nearly perfectly circular cross-section, but has an axial continuous slot 24.
- Both the inner surface and the outer surface of Graphitrings 22 is designed wavy. This can be seen as a consequence of axially extending beads.
- the friction is increased, the graphite ring 22 thus sits particularly firmly on the discharge vessel 10. It will be particularly well balanced and Strengthens ⁇ th in detail.
- Through the slot 24, one and the same graphite ring can also be used with discharge vessels 10, in which the shank 12 deviates from the basic shape by being either not perfectly cylindrical or having a radius different from a nominal radius.
- a base sleeve 26 shown in half in FIG. 3, is now pushed onto the graphite ring.
- a funnel 28 is formed, which serves to guide the electrode holding rod 18, thus making it easier to plug the base sleeve 26 onto the discharge vessel 10 with the electrode holding rod 18.
- the base sleeve 26 has a circular cross-section and has a series of axial slots 30. These cause individual parts such as tongues 32 to move independently of the other corresponding parts (tongues) 32. Through the slots 30 therefore an increased flexibility is contraindicated ⁇ ben.
- a clamping ring 34 For fastening the base shell 26 to the discharge vessel 10 will be a clamping ring 34 which is shown in perspective in Fig. 4 in detail, placed ⁇ on the base shell 26.
- the clamping ring 34 has a multiplicity of axially extending beads 36. The provision of this plurality of beads 36 gives the clamping ring 34 a wave-shaped profile. Due to the large number of beads 36, the clamping ring 34 is flexible. Should the shaft 12 of the discharge vessel 10 have once been particularly large, the clamping ring 34 yields outwards due to the beads and does not exert excessive force on the shaft 12. The beads thus ensure that the contact pressure which the clamping ring 34 exerts on the base sleeve 26, the graphite ring 22 and the shaft 12 is substantially constant. For this reason, the entire production method explained with reference to FIGS. 1A to 1D can be automated.
- the graphite ring 22 is preferably made of pure graphite
- the base sleeve 26 is made of heat-treated steel, and the clamping ring 34 made of brass (CuZn37).
- the bead 42 is slipped outwards, ie away from the interior of the clamping ring. As a result, a local increase in the pressing force in the direction of the lamp shaft is avoided.
- the clamping ring 40 is made of nickel plated brass ⁇ system (CuZn37) the wall thickness of 0.75 mm.
- FIG. 6 shows the measurement results of the clamping ring shown in FIGS. 5a and 5b with a bead and three different widths A, B, C in comparison to a standard clamping ring D without beads.
- the measured pressing force in Newtons (N) and on the X-axis the density of the graphite in g / cm 3 is plotted.
- the width b of the clamping ring 40 according to the invention is 15 mm in case A, 20 mm in case B and 25 mm in case C.
- the clamping ring 40 compensates for the higher density and therefore lower compliance of the graphite ring from largely.
- the standard clamping ring increases the pressing force executed ⁇ gen with increasing graphite density, thus increasing the Ge ⁇ driving of damage to the lamp vessel in the base area.
