Definitions

  • the invention is based on a high-pressure discharge lamp according to the preamble of claim 1. These are metal halide lamps with high-power two-sided pinching of at least 1600 W.
  • the invention further relates to an associated luminaire.
  • Such lamps are from the EP 391,283 and EP 451 647 known. They are basically suitable for horizontal and vertical arrangement in a reflector.
  • a discharge lamp which is suitable for both horizontal and vertical operation in a luminaire.
  • This high-pressure discharge lamp has as characteristics an elongate discharge vessel as the only one
  • a piston which defines an axial axis of symmetry and which is sealed on both sides by sealing parts, for example by pinching or melting and which encloses a discharge volume, wherein two electrodes face each other on the axis, and which contains an ionizable filling of mercury, noble gas and metal halides, and Power supplies which are connected to the electrodes via foils and which emerge at the ends of the discharge vessel, wherein the lamp receives a power of at least 1600W.
  • the shafts are designed as pins with a diameter of 0.5 to 1.15 mm.
  • the halogen for the halides is composed of the constituents iodine and possibly bromine, where either only iodine or bromine and iodine are used together, with the atomic ratio bromine / iodine being a maximum of 1.45.
  • a pinch which is adjacent to an electrode, provided with a reflective coating.
  • the coating is a metallic or non-metallic layer, in particular zirconium oxide. This coating extends from the pinch edge at least 2 mm towards the film, in particular at least over the entire length of the shaft introduced into the pinch.
  • the lamp is vertically installed in a reflector, so with a maximum deviation of 45 ° to the vertical.
  • this coating is applied on both sides of both bruises.
  • a part of the two seals can be frosted, as is known.
  • the matting is preferably a layer roughened by sandblasting or etching.
  • metal halides of Hg and from the group of elements Cs and rare earth metals such as Dy or Tm or Ho are suitable, since with them a color temperature of at least 3300 K, preferably at least 3800 K, can be well adjusted.
  • thallium halide in particular thallium iodide, can be used to improve the color rendering index.
  • the high-pressure discharge lamp is designed to be particularly compact in that the discharge vessel (2) is the only piston.
  • the high-pressure discharge lamp is characterized by the use of electrodes with shaft and head, in which the shafts have a diameter of at most 1.15 mm.
  • Such thin shafts have not been used for such lamps, since the filling previously contained relatively much bromine for an optimal halogen cycle, which specifically attacks the shafts.
  • a relatively low bromine filling can be better used in complete departure from the current doctrine, using as bromide a bromine / iodine mixture up to an atomic ratio of maximum 1.45 is usable.
  • the low-bromine filling is particularly advantageous when low color temperatures are desired with the light color neutral white with color temperatures between 3300 and 4800 K, as halide here either iodine alone or a bromine / iodine mixture up to an atomic ratio of not more than 1.45 preferred is. Such low color temperatures could not be realized at all in generic lamps so far. Such little bromine loads the shafts little. Typical is the use of pure iodine at low powers (typically 1600 W power) up to a ratio Br / J of 1.0 ⁇ 0.2 at higher powers (typically 2000 W). the mentioned capacity refers to standard operation.
  • the thin shafts are particularly important because they concern a critical location in the functioning of the lamp.
  • the pin-shaped shaft is melted in the quartz glass and is there under high heat stress and high voltage.
  • the quartz glass does not adhere to the pin, but it inevitably forms a capillary between pin and quartz glass. Part of the filling condenses in the capillary, forming a dead volume for the filling. This effect leads to the previously observed poor maintenance of such lamps, which, however, seemed unavoidable.
  • Turning away from the current technology now shows that thin pins with careful selection of the Bromsteils not only sufficiently stable, so that the current load of typically 10 to 20 A no problem, but have the great advantage of a much lower associated dead volume , Because the thinner a pin, the narrower is the dead volume around it in the seal.
  • thin pins improve the Heat accumulation in the area of the electrodes.
  • only one electrode can be equipped with a thin shaft in vertical operation, while the other has a conventional thick shaft with typically 1.5 mm diameter.
  • the thin shaft also allows for a relatively long distance between film and discharge volume, which reduces the risk of explosion and lowers the heat load on the film. The risk of explosion is due to the notch effect of the film in the quartz glass. The longer distance increases the dead volume only insignificantly, so that it is still considerably below the value of thick pins as previously used.
  • a typical axial length of the pin in the quartz glass, calculated from the pinch edge to the beginning of the film, is now 5 to 7 mm, while previously maximum values of 4 mm were used.
  • An optimum for the diameter of the shaft in terms of stability on the one hand and dead volume on the other hand is about 0.9 to 1.1 mm.
  • the shafts are made for example of conventional tungsten material.
  • Such lamps can be operated with a moderate cycle, resulting in excellent maintenance.
  • the lamps not only reach an exceptionally long service life in the order of 2500 to 6000 and typically 4500 hours, but also an excellent stability of the lighting properties. This is on the order of at least 90% at 1500 hrs.
  • the lamp according to the invention achieves a lifetime of at least 2500 hours even in the case of the particularly critical vertical operation in a compact luminaire, as a rule the service life is at least 4000 hours.
  • the vertical operation enables a particularly high luminaire efficiency.
  • the light color is neutral white, well suited for the highest color rendering requirements neutral white de luxe (NDL) with a color temperature of about 4100 to 4400 K and a Ra of at least 85.
  • NNL neutral white de luxe
  • the lamp according to the invention is also suitable for indirect lighting, for example with mirror projector systems, in which a high luminous flux is required.
  • light-active metal halide fillers contain small amounts of sodium and / or manganese as an ingredient. This can be achieved high luminous efficiencies and the desired color components. In contrast, a high sodium content leads to increased corrosion of the discharge vessel, although it is usually made of quartz glass. Therefore, the proportion of Na is chosen as relatively low as possible in addition to the other ingredients thallium, cesium and common rare earth metals such as Dy, Ho or Tm, and in particular sodium is wholly or partially replaced by manganese.
  • the ends of the discharge vessel can be coated only briefly, typically 2 mm, with a reflective layer. This is especially true for neutral white fillings with color temperature of 4000 to 4800 K. Overall, this increases the temperature of the cold spot, but also the final film temperature and the wall load, so that they achieve optimum values.
  • An optimum film end temperature is 350 to 390 ° C. It can be adjusted, for example, by the distance of the film from the discharge volume and its length. At higher temperatures threatens early corrosion, which leads to a shortened life.
  • the wall load is best at values of about 60 to 75 W / cm 2 .
  • fillings with little or no Na content are preferably used.
  • a longer length of the reflective layer is recommended here. It should, starting from the pinch edge, at least include the shaft up to the film and in particular at least still the part of the film on which the shaft is welded. Preferably, it extends a few millimeters beyond.
  • the matting should therefore encompass the area of the outer end of the film.
  • it extends to the end of the bruise.
  • she can at least extend to the middle of the film, under circumstances also significantly beyond, for example, to the inner end of the film.
  • Typical distances between the electrode tips are 25 to 35 mm for particularly compact luminaires, but also distances up to 100 mm or more are possible. A minimum distance is 20 mm.
  • FIG. 1 is schematically illustrated a 1600 W high pressure discharge lamp 1 without outer bulb with a length of about 190 mm, as for example in U.S. Patent 5,142,195 is described in more detail. It is intended for use in reflectors, being arranged axially to the reflector axis.
  • the discharge vessel 2 made of quartz glass defines a longitudinal axis X and is designed as a barrel body 3, whose generatrix is a circular arc.
  • the discharge volume is about 20 cm 3 .
  • the rod-shaped tungsten electrodes 6 with deferred helix 7 as a head are axially aligned at the two ends of the discharge vessel in bruises 5.
  • the electrodes 6 are attached to foils 8 in the pinch seal 5, where external power supply lines 9 begin.
  • a ceramic base 11 with putty (not shown) is attached.
  • the discharge vessel 2 contains a filling of a noble gas as a starting gas, mercury and metal halides.
  • HgBr2 and HgJ2 as well as the light active filling NaJ, CsJ, TIJ and DyJ3 as well as TmJ3 are used.
  • the ratio Br / J is about 0.2.
  • the lamp is operated horizontally.
  • the cold filling pressure of the starting gas is at most 1 bar.
  • the light color is neutral white with a typical color temperature of 4000 K realized by the filling.
  • a typical diameter of the shaft 6 of the electrode is 1.0 mm.
  • a relatively narrow coating 9 on the lower pinch 3a reduces the wall load caused thereby. Desirable is a value of the wall load of at most 75 W / cm 2 . Good results are given by a wall load of 65 to 70 W / cm 2 .
  • the heat accumulation effect is further increased by the shaft 23 extended and the film 8 is shortened, each viewed in axial length. The embedding of the shaft in the pinch is then at least 6 mm.
  • the coating 9 extends approximately from the pinch edge to the end of the shaft on the film.
  • the ends of the coating are designated by the reference numerals 30 and 29.
  • a matting 12 is also applied on both shafts 3a and 3b and extends in both the upper and the lower pinch approximately from the outer end 20 of the pinch up to 60% of the length of the film. The inner end of the matting is designated 31.
  • FIG. 3 another embodiment is shown. It is a 2000 W metal halide lamp 40 for horizontal burning position, otherwise similar to FIG. 2 is described. It is suitable for neutral white light colors from 3500 to 4800 K.
  • the uniform temperature distribution allows the use of thin pins 41 as a shaft (0.5 to 1.15 mm in diameter), which can be embedded more tightly in the quartz glass during squeezing and reduce the volume of capillaries surrounding them as a dead space.
  • Such a thin shaft 41 must be compatible with the design of the halogen cycle process, especially by careful selection of the bromine / iodine ratio as shown above. Such thin shafts also limit the heat dissipation, so that at this point an additional heat accumulation is created, which prevents the formation of a metal halide swamp.
  • a symmetrical reflector coating 42 on the two pinches 43 with a small axial length is possible, which avoids shading.
  • a narrow coating 42 on the two pinches 43 reduces the wall load caused thereby to about 60 W / cm 2 .
  • the heat accumulation effect is further increased by the shaft 41 extended and the film 44 is shortened, each viewed in axial length.
  • the embedding of the shaft in the pinch is about 12 mm.
  • the coating 42 extends from the pinch edge 42a to 2 mm beyond the end of the shaft on the film, the outer end being designated 42b.
  • the ends of the coating are designated by the reference numerals 30 and 29.
  • a matting 45 extends on both bruises approximately from the outer end 46 of the pinch up to 60% of the length of the film.
  • the inner end of the matting is designated 47. It overlaps slightly with the outer end of the coating.
  • the metal halide used is HgBr2 and the light-active filling MnJ2, CsJ, TIJ and DyJ3 and TmJ3.
  • the ratio Br / J is about 1.1.
