Definitions

  • the invention relates to a high-pressure discharge lamp according to the preamble of claim 1.
  • Such lamps are in particular high-pressure discharge lamps with a ceramic discharge vessel for general lighting.
  • US Pat. No. 4,970,431 discloses a sodium high-pressure discharge lamp in which the bulb of the discharge vessel is made of ceramic. At the cylindrical ends of the discharge vessel fin-like extensions are attached, which are used for heat dissipation.
  • EP-A 506 182 are coatings of graphite or carbon o.a. known, which are applied to ceramic discharge vessels at the ends to effect cooling.
  • the object of the present invention is to provide a high-pressure discharge lamp whose color spread is significantly reduced compared to previous lamps.
  • the high pressure discharge lamp is equipped with a ceramic elongate discharge vessel.
  • the discharge vessel defines a lamp axis and has a central portion and two end portions, each sealed by seals, with electrodes anchored in the seals extending into the discharge volume enveloped by the discharge vessel, and a charge containing metal halides in the discharge volume is housed.
  • at least one end region is seated in an annular structure which, as far as its basic body is concerned, extends outwards substantially parallel to the axis and is spaced from the seal.
  • the seals are preferably capillaries.
  • the invention relates in particular to lamps with an increased aspect ratio, or else lamps which have shortened structures for the seals.
  • the end region preferably has a tapering inner contour in the electrode rear space. That is, the central part of the discharge vessel has a maximum or constant inner diameter ID and the end regions have a smaller inner diameter.
  • the ring structure is preferably formed concentrically outside around the electrode construction or the seal at the end region.
  • the discharge vessel typically consists of aluminum-containing ceramics such as PCA or else YAG, AlN, or A1YO3.
  • a freestanding cooling structure spaced apart from the seal is used, which in particular is itself formed of ceramic and, in particular, can be an integral part of the end region.
  • it can also be a separate component made of translucent Ceramics act like Al 2 O 3 or AlN, for example also from steatite. The separate component is attached by means of cement or adhesive to the end of the discharge vessel.
  • the invention is particularly suitable for highly loaded metal halide lamps in which the ratio between the inner length IL and the maximum inner diameter ID of the discharge vessel, the so-called aspect ratio IL / ID, is between 1.5 and 8.
  • the temperature gradient of highly loaded burners which typically reach a wall load of at least 30 W / cm 2 in the axial length between the electrodes, can be selected by choosing the starting point for the electrodes -A-
  • Cooling structure can be influenced and adjusted.
  • the constancy of the color temperature and the yield of the resulting metal halide lamp can be significantly improved.
  • metal halide lamps which contain at least one of the halides of Ce, Pr or Nd, in particular together with halides of Na and / or Li. Otherwise, color temperature fluctuations due to distillation effects occur here.
  • the seals are advantageously designed as capillaries.
  • they can also be embodied differently, see, for example, DE-A 197 27 429, where a cermet pin is used.
  • DU outer diameter of the capillary
  • its wall thickness is about 0.3 to 3 mm.
  • the end face connecting the inner diameter with the outer diameter can be beveled.
  • the coating should be highly viscous. Suitable materials are in particular graphite or carbon, ie other carbon modifications such as DLC (diamond-like carbon).
  • the cooling behavior can also be controlled by covering a part of the ring like the end face with a coating of high emissivity.
  • PCA or any other common ceramic can be used as the material of the piston.
  • the choice of filling is subject to no particular restriction.
  • discharge vessels for high-pressure lamps with approximately uniform wall thickness distribution and slim-running end shapes have hitherto exhibited partially high color spread due to the high distribution of the metal halide filling in the interior of the discharge vessel.
  • the filling condenses in the area behind a line, which is determined by projection of the electrode tip on the inner burner surface.
  • the filling position on a zone of the surface in the interior of the discharge vessel, which corresponds to a narrow temperature range, and in the residual volumes of -eventuell existing capillaries into is not yet sufficiently precisely adjustable.
  • Previous discharge vessels often have a shape with increased wall thickness at the end surfaces, eg in cylindrical burner shapes, thereby creating an enlarged end surface.
  • Another problem is the increased by the wall thickness-dependent specific emission coefficient of the ceramic radiation of IR radiation during operation of the discharge vessel in the evacuated or gas-filled outer envelope.
  • Spherical discharge vessels or those with hemispherical end shapes or conically tapering end shapes or elliptically shaped end shapes and cylindrical center part with a relatively high aspect ratio of IL / ID of about 1.5 to 8 present particularly serious problems. Due to the tapering transition in the region of the seal, usually a capillary, partially insufficient cooling effects at the end of the discharge vessel and thus an insufficient determination of the temperature, which is not sufficient for a precise filling deposit in a narrow temperature range of the inner wall.
  • Figure 10 Another known solution (Figure 10) are fins or fin-like formations. Although these increase the cooling surface, but they form a thermal bridge between see burner end and sealing, especially when short cooling lengths are preferred and the cooling structure has an increased number of cooling fins.
  • the cooling structure is wholly or partially provided with a coating. It consists of a material having in the near infrared (NIR), in particular in the wavelength range between 1 and 3 microns, compared to the ceramic material of the cooling structure an increased hemispherical emissivity ⁇ in the temperature range 650-1000 0 C.
  • the coating should preferably be applied in the region of the transition between the end of the discharge vessel and the seal. High-temperature-resistant coatings with hemispherical emission coefficients ⁇ are suitable as coating materials, it being preferred for ⁇ that ⁇ ⁇ 0.6.
  • graphite mixtures of A12O3 with graphite, mixtures of A12O3 with carbides of the metals Ti, Ta, Hf, Zr, as well as of semi-metals such as Si. Also suitable are mixtures which additionally contain other metals for adjusting any desired electrical conductivity.
  • both measures can be suitably combined with each other, so that part of the surface radiation increase takes place via an enlargement of the surface by the ring structure and at the same time a part by the coating of parts of this ring structure or of the adjacent colder sealing areas.
  • the total mass of the discharge vessel increases only insignificantly by this type of annular cooling and thus remains below a critical value that would adversely affect the start-up behavior of the lamp during ignition. There is thus a sophisticated compromise between good ignition and effective cooling.
  • This measure allows a very high color stability under the conscious acceptance of a bad isotherm. This is done in departure from the previous objective of the best possible isotherm and allows the zone of condensation of the filling to be determined precisely by deliberately designing a temperature gradient.
  • the cooling effect can be controlled in particular by the maximum height of the annular cooling, in particular if it attaches to the end region of the discharge vessel, since, depending on the approach height, the discharge takes place from another temperature level.
  • FIG. 2 shows a detail of the discharge vessel from FIG. 1 in perspective (FIG. 2 a) and in a longitudinal section (FIG. 2 b);
  • Fig. 3-4 shows another embodiment of an end portion of a discharge vessel
  • FIG. 5-6 another embodiment of a discharge vessel
  • FIG. 7 shows a further embodiment of an end region of a discharge vessel
  • 11-13 further embodiments of an end region of a discharge vessel.
  • Figure 1 shows a metal halide lamp 1. It consists of a tubular discharge vessel 2 made of ceramic, in which two electrodes are inserted (not visible).
  • the discharge vessel has a central part 5 and two ends 4. At the ends sit two seals 6, which are designed here as capillaries.
  • the discharge vessel and the seals are made integrally from a material such as PCA.
  • the discharge vessel 2 is surrounded by an outer bulb 7, which terminates a base 8.
  • the discharge vessel 2 is in the outer bulb by means of a frame which includes a short and long power supply 11 a and II b, supported.
  • a ring cooling structure 10 which rotates about the seal.
  • FIG. 2a shows a ring cooling structure 10 in a perspective view in conjunction with a short seal 16.
  • FIG. 2b shows a longitudinal section of the region of a seal 16.
  • the ring cooling structure 10 sets in the tapering end region 4 of the discharge vessel 2 and surrounds the seal at some distance ,
  • FIG. 3 shows a ring cooling structure 13 which, instead of a constant inner diameter and outer diameter, has crescent-shaped or semicircular cut-out structures 19 which attach externally to the ring 13.
  • the inner diameter ID is constant
  • the outer diameter AD varies periodically.
  • small recesses 20 interrupt the ring structure 13, see Figure 4. This aims to increase the radiating surface.
  • the number of recesses is advantageously up to three, as shown here.
  • FIG. 5 shows a discharge vessel 2, in which the seal is realized by a capillary.
  • the cooling ring 13 has a recess 20.
  • recess here is meant an interruption whose angle length is very small in the Compared to the angular length of the remaining ring.
  • the recesses typically together make up at most 10% of the total angular length of 360 °. This value should be chosen as low as possible because the interruptions reduce the cooling capacity.
  • the cooling effect on the surface zone of the burner vessel can be set locally and tailored to the particular requirements.
  • the starting point of the cooling ring on the tapered end portion 4 is given by the inner diameter DRI, wherein DRI is in the range between 95% and 25% of the maximum diameter Dmax of the discharge vessel. Preferably, DRI is between 80% and 25% of Dmax.
  • the wall thickness TH of the tapered end portion 4 is often not constant as shown here.
  • the orientation of the annularly arranged cooling structure is selected (FIG. 6) such that the point of attachment of the ring structure lies outside the narrowest point E of the tapered end region 4.
  • the entrance of the capillary is formed as a flat surface 25 which is transverse to the lamp axis, whereby a narrowest point inevitably results.
  • DRA is the outer diameter of the ring structure.
  • the minimum wall thickness in the end region preferably has 20-80% of the maximum wall thickness in the end region, as occurs in particular at the beginning of the taper.
  • WD is the wall thickness in the center of the discharge vessel. If possible, the ring structure 13 should avoid that a wall thickness TH> WD occurs in the tapered end region 4, since otherwise an increased heat flow into the capillary cross-sectional area occurs and this can lead to increased heat conduction losses.
  • FIG. 7 shows an exemplary embodiment of a discharge vessel 30, in which the end 31 of the discharge vessel does not taper, but the discharge vessel has a constant diameter DD.
  • the capillary 6 is seated in a plug 32.
  • the ring structure is inserted as a further plug-like cylindrical part 33 between the plug 32 and the end 31 of the discharge vessel and sintered in each case with the plug 32 and the discharge vessel 30.
  • FIG. 11 shows an exemplary embodiment in which a ring structure 39 has an axially parallel main body 40 which surrounds a stopper and which has a radiating body which is inclined outward from the axis in the form of a protruding circumferential fin or even individual spikes 41. It can also be arranged several spines axially one behind the other on a base body.
  • the deflection of the radiation body against the longitudinal axis is about 90 ° in order to avoid back reflection on the capillary 6 as far as possible. It is advantageous that the projecting length AB clearly extends the diameter DU of the discharge vessel 38 in order to minimize any return reflection.
  • Figure 12 shows an embodiment in which the base body 40, a plate-like end portion is attached as a radiating 43, which forms approximately at an angle of 45 ° to the longitudinal axis.
  • Figure 13 shows an embodiment in which the problem of back reflection has been solved in another way.
  • the ring structure is tapering at the end remote from the discharge, so that its inner wall side, which faces the capillary, is chamfered (44) so that the emitted radiation reaches the outside obliquely after reflection at the capillary.
  • an IR-reflecting coating 50 is preferably also applied to at least one of the two capillary surfaces and / or the inner side of the ring structure.
