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 for general lighting or for photo-optical purposes.
- the object of the present invention is to provide a high-pressure discharge lamp whose ignition behavior is significantly improved compared to previous lamps and in which no damage due to the high voltage is to be feared.
- an object of the present invention is to provide a compact high voltage pulse generator. This object is solved by the characterizing features of claim 14.
- a high-voltage pulse with at least 1.5 kV, which is necessary for igniting the lamp is now generated by means of a special temperature-resistant spiral pulse generator, which is integrated in the outer bulb in the immediate vicinity of the discharge vessel. Not only a cold ignition but also a hot re-ignition is possible.
- the spiral pulse generator used now is in particular a so-called LTCC component.
- This material is a special ceramic that can be made temperature resistant to 600 0 C.
- LTCC has already been used in connection with lamps, see US 2003/0001519 and US Pat. No. B 6,853,151. However, it has been used for quite different purposes in practically barely temperature-stressed lamps, with typical temperatures below 100 ° C.
- the spiral pulse generator is a component that combines the properties of a capacitor with those of a waveguide to generate ignition pulses with a voltage of at least 1.5 kV.
- two ceramic "green foils" are printed with metallic conductive paste and then wound up into a spiral and finally pressed isostatically into a shaped body.
- the following co-sintering of metal paste and ceramic film takes place in air in the temperature range between 800 and 900 0 C. This processing allows a range of applications of the spiral pulse generator to 700 0 C temperature load.
- the spiral pulse generator can be accommodated in the immediate vicinity of the discharge vessel in the outer bulb, but also in the base or in the immediate vicinity of the lamp.
- a spiral pulse generator can be dimensioned so that the high-voltage pulse even allows a hot re-ignition of the lamp.
- an ignition unit which furthermore comprises at least one charging resistor and a switch.
- the switch can be a spark gap or a Diac in SiC technology.
- the ignition unit is extremely compact, since j a load resistance is integrated in the high voltage pulse generator.
- the charging resistor is not a separate component, which is only connected to the spiral pulse generator. Since the charging resistor must in any case meet the same conditions as the spiral pulse generator in terms of its temperature resistance, it is recommended that it be made of LTCC material similar to the spiral pulse generator.
- the charging resistor can be integrated at the inner edge in the spiral pulse generator, so that both are designed together as an LTCC ceramic component. This component is fixed to about 600 0 C temperature. As a result, a contact point is avoided, which would also otherwise be carried out temperature-resistant. Thus, apart from the high voltage switch, usually a spark gap or diac, no other components are needed.
- any conventional glass can be used, ie in particular tempered glass, Vycor or quartz glass.
- the choice of filling is subject to no particular restriction.
- Fig. 1 shows the basic structure of a spiral pulse generator
- Fig. 3 shows the basic structure of a high-pressure sodium lamp with spiral pulse generator in the outer bulb.
- FIG. 4 shows the basic structure of a metal halide lamp with spiral pulse generator in the outer bulb.
- Fig. 5 shows a metal halide lamp with spiral pulse generator in the outer bulb
- Fig. 6 is a metal halide lamp with spiral pulse generator in the base.
- Figure 1 shows the structure of a spiral pulse generator 1 in plan view. It consists of a ceramic cylinder 2, in which two different metallic conductors 3 and 4 are spirally wrapped as a film strip.
- the cylinder 2 is hollow inside and has a given inner diameter ID.
- the two inner contacts 6 and 7 of the two conductors 3 and 4 are connected to one another via a spark gap 5.
- the spiral pulse generator is either wound from two ceramic paste-coated ceramic foils or built up from two metal foils and two ceramic foils.
- An important parameter is the number n of turns, which should preferably be in the order of 5 to 100.
- This winding assembly is then laminated and then sintered, creating an LTCC component.
- the thus created spiral pulse generators with capacitor property are then connected to a spark gap.
- the spark gap can be located at the inner or the outer terminals or even within the winding of the generator.
- a spark gap can be used which is based on SiC and very stable in temperature.
- the switching element MESFET from the company Cree can be used. This is suitable for temperatures above 350 0 C.
- a ceramic foil in particular a ceramic strip such as Heratape CT 707 or preferably CT 765 or a mixture of the same, is preferably used as the dielectric, in each case by Heraeus. It has a thickness of the green film of typically 50 to 150 microns.
- Ag conductive paste such as "Cofirable Silver", also from Heraeus, is used as the conductor.
- a concrete example is CT 700 from Heraeus. Good results are also provided by the metal paste 6142 from DuPont. These parts are easy to laminate and then burnout and sintering together (co-firing).
- the ID of the Spiral Pulse Generator is 10 mm.
- the width of the individual strips is also 10 mm.
- the film thickness is 50 ⁇ m and also the thickness of the two conductors is 50 ⁇ m in each case.
- FIG. 3 shows the basic structure of a sodium high-pressure lamp 10 with ceramic discharge vessel 11 and outer bulb 12 with spiral pulse generator 13 integrated therein, an ignition electrode 14 being mounted on the outside of the ceramic discharge vessel 11.
- the spiral pulse generator 13 with the integrated charging resistor is housed together with the spark gap 15 in the outer bulb.
- FIG. 4 shows the basic construction of a metal halide lamp 20 with integrated spiral pulse generator 21, wherein no ignition electrode is attached to the outside of the discharge vessel 22, which may be made of quartz glass or ceramic.
- the spiral pulse generator 21 with the integrated charging resistor is housed together with the spark gap 23 in the outer bulb 25.
- FIG. 5 shows a metal halide lamp 20 with a discharge vessel 22, which is held by two supply lines 26, 27 in an outer bulb.
- the first lead 26 is a short-angled wire.
- the second 27 is essentially a rod that leads to the socket remote 28 implementation.
- an ignition unit 31 is arranged, which contains the spiral pulse generator, the spark gap and the charging resistor, as indicated in Figure 4.
- FIG. 6 shows a metal halide lamp 20 similar to FIG.
- FIG. 5 with a discharge vessel 22, which is held by two supply lines 26, 27 in an outer bulb 25.
- the first lead 26 is a short-angled wire.
- the second 27 is essentially a rod that leads to the socket remote 28 implementation.
- the ignition unit is arranged in the base 30, both the spiral pulse generator 21 with the integrated charging resistor and the spark gap 23rd
- This technique can also be used for electrodeless lamps, where the spiral pulse generator can serve as a starting aid.
- this compact high-voltage pulse generator is in the ignition of other devices.
- the application is particularly advantageous in so-called magic spheres, in the generation of X-ray pulses and in the generation of electron beam pulses.
- a use in a car as a replacement for the usual ignition coils is possible.
- the invention develops particular advantages in cooperation with high-pressure discharge lamps for car headlights, which are filled with xenon under high pressure of preferably at least 3 bar and metal halides. These are particularly difficult to ignite because of the high xenon pressure, the ignition voltage is more than 10 kV.
- a spiral pulse generator with integrated charging resistor can either be plugged into the base of the Car lamp or be housed in an outer bulb of the lamp.
- the invention has very particular advantages in combination with high-pressure discharge lamps which do not contain mercury. Such lamps are particularly desirable for environmental reasons. It contains a suitable metal halide charge and, in particular, a noble gas such as xenon under high pressure. Because of the lack of mercury, the ignition voltage is particularly high. It is more than 20 kV. Currently trying to accommodate the components of the ignition unit in the base. A spiral pulse generator with built-in charging resistor can either be housed in the base of the mercury-free lamp or in an outer bulb of the lamp.
