Definitions
- the invention relates to a gas discharge lamp, in particular for motor vehicle headlights.
- Gas discharge lamps or high pressure gas discharge lamps are already standard in motor vehicle headlights today used because it is a much better Luminous efficacy compared to conventional incandescent lamps have and the spectral composition of the light of the daylight is very similar.
- These gas discharge lamps need depending on the ignition method used an ignition voltage between the electrodes between 6 kV up to approx. 25 kV. This voltage conducts the ionization in the Gas filling. For burning, d. H. to maintain of the arc between the electrodes, then only low voltages of approx. 50 V are required, because then there are already enough charge carriers.
- Auxiliary or ignition electrodes which are wire-shaped are, with an auxiliary electrode also on the outside the lamp may have been evaporated.
- the auxiliary or ignition electrodes are each connected to a main electrode, which has the disadvantage that all electrodes and their feed lines must be designed to withstand high voltages have to.
- the same disadvantage occurs with corresponding internal metallizations on how they cited from the Book "Lamps and Lighting", pages 255, 257 and 279, known are.
- the gas discharge lamp according to the invention with the features of the main claim has the advantage that when maintained a safe ignition behavior the ignition voltage can be significantly reduced, only relative minor design changes to the lamp or whose electrodes are required. In terms of this can reduce the demands on the components thereby making a significant contribution to reducing costs for electronic ballast and also for the gas discharge lamp be done by yourself since there For example, much lower requirements for the High voltage strength of the lamp base and the inside arranged components are to be provided. A special one significant reduction in the cost of the gas discharge lamp occurs then on when the ballast is in the lamp base is integrated.
- a particularly effective reduction in ignition voltage can be achieved by at least one ignition electrode which is arranged separately from the main electrodes.
- the ignition electrode is advantageously separate third electrode on the outside of the burner vessel arranged and forms one of the main electrodes Ignition distance.
- This version is only one minor design change in the conventional Gas discharge lamps necessary, that is, these Ignition electrode can also be retrofitted to conventional gas discharge lamps be attached, especially to one of tubular extensions that lead through the electrodes for the main electrodes of the lamp included. Conveniently encompasses one of the two Main electrodes ring-shaped or partially ring-shaped. If the tubular extension of the burner vessel a constriction has, the ignition electrode in an advantageous manner this constriction arranged or extends in this, because then a particularly short ignition distance and a correspondingly significant reduction in the ignition voltage can be achieved.
- the ignition electrode can either be used as real third electrode with no galvanic connection one of the main electrodes are formed, which the Operation of the ignition part of the ballast completely allows separate from the rest of the electronics. This means that only the ignition part of the ballast must be resistant to high voltages, but not that Most of the components used for the low-impedance Normal operation are required.
- the metallization encompasses the electrode feedthrough the main electrode at least partially and preferably extends substantially to the free End area of this main electrode, so that from there can form a sliding spark gap.
- a clearer one Reduction of the ignition voltage can be achieved through a strip-shaped or light reflector-like metallization achieved that are at least along the range of Burning distance up to the area of the other main electrode extends.
- the light reflector-like metallization extends preferably essentially over the in the Operating position lower half of the combustion chamber of the burner vessel and has the additional advantage that it has the Function of the in a motor vehicle headlight for that Low beam takes on the otherwise required aperture, to set the prescribed light-dark limit and oncoming traffic before glare protect. With reflective properties, the most of the otherwise lost light for illumination use the road provided an application in a motor vehicle headlight is provided.
- Gas discharge lamp or high pressure gas discharge lamp consists essentially of a burner vessel 10, which Glass or other clear, temperature-resistant Material exists and a central combustion chamber 12 with flattened spherical shape or ellipsoidal shape has two tubular on opposite sides Has extensions 13, 14.
- the outer end areas of this tubular extensions 13, 14 are gas-tight electrode bushings 15, 16 for two rod-shaped main electrodes 17, 18 formed from both sides stretch slightly into the combustion chamber 12. Forms between these two main electrodes 17, 18 during operation of the arc 19.
- Outer electrical connecting wires 20, 21 are connected to the two main electrodes 17, 18 via connecting elements 22 connected, which is formed, for example, as molybdenum foils could be.
- the electrical connection wires 20, 21 still run a certain distance in tube-like Extensions 23, 24 of the extensions 13, 14, the Electrode bushings 15, 16 between the extensions 13, 24 and the tubular extensions 23, 24, the connecting elements 22 and the respective connection ends of the Main electrodes 17, 18 and lead wires 20, 21 included.
- connection pipes of the combustion chamber 12 with the electrical Lead wires 20, 21 connected main electrodes 17, 18th inserted these connecting pipes in the connection area are fused so that the connection areas are melted and the extensions 13, 14 on the one hand and the tubular extensions 23, 24 on the other hand formed on both sides of the electrode bushings 15, 16 become.
- the electrical connecting wires 20, 21, the connecting elements 22 and the tubular extensions 24, 24 waived of course one Realization of such a simpler version as well would be possible in principle.
- an annular, band-shaped metallization On the extension 13 arranged on the left of the combustion chamber 12 there is an annular, band-shaped metallization, which forms an ignition electrode 25.
- This ignition electrode 25 thereby concentrically engages around the main electrode 17, wherein a partial ring shape can also take the place of the ring shape.
- the ignition electrode 25 is outside the burner vessel 10 electrically connected to the right main electrode 18, while the concentric in the ignition electrode 25 Main electrode 17 with a different voltage termination of a ballast, not shown Generation of a burning and ignition voltage is connected.
- the distance between the ignition electrode 25 and the main electrode 17 is significantly less than the distance between the two main electrodes 17, 18, one is sufficient much lower ignition voltage for the ignition.
- the ignition voltage of 18 kV can be reduced to 4 kV. After an ignition spark has been created or ignition arc this migrates due to the thermal Conditions in the combustion chamber to the combustion path between the main electrodes, which creates the arc 19, which has an electrical curve upwards because the hot gas due to its lower density in the arc moves upwards against gravity.
- the ignition electrode 25 is used as a real third electrode without galvanic connection with one of the two main electrodes 17, 18. Then the ignition voltage in a separate ignition part the circuit is formed separately from the rest of the electronics be so that only this ignition part is resistant to high voltages needs to be, but not the majority of the others Components that are used for low-resistance firing Generation of the burning voltage required.
- Fig. 3 is an ignition electrode 64 in the form of an outer metallization or external metal vapor deposition.
- metallization 65 Starting from an all-round metallization 65, extends a wide, reflector-like metallization 66 to left main electrode 17 and opens there at one of these left main electrode 17 encompassing metallization ring 67.
- the reflector-like metallization 66 extends over the lower in the operating situation shown Half of the combustion chamber 12, ie up to the height of the main electrodes 17, 18.
- narrower ones are also Possible designs.
- an indentation 40 of the glass wall intended.
- One designed as a metal strip Ignition electrode 41 extends along the left extension 13 into this indentation 40, which results in a particularly small distance from the left main electrode 17 and a correspondingly low ignition voltage is reached.
- Electrode shapes e.g. Metallizations occur, taking either extend these electrodes into the indentation 40 or arranged in a ring.
- All non-oxidizable metals with a melting point above approx. 1000 ° C can be used for external metallizations.
