Definitions
- the invention relates to a device for igniting and operating a High-pressure gas discharge lamp in a motor vehicle, with a control device to generate the operating voltage of the high pressure gas discharge lamp, with an ignition device which generates an ignition voltage and the Operating voltage superimposed, and with means for radio interference suppression High pressure gas discharge lamp.
- Such a facility, made known by one of the applicant Manufactured series device is shown schematically in Figure 3.
- the ignition device is integrated in the control unit (SG).
- the Control unit (SG) generates the operating voltage of the High pressure gas discharge lamp (GEL), the ignition device among others by means of an ignition transformer (ZT) to ignite the High-pressure gas discharge lamp generates the required high-voltage pulse and the operating voltage superimposed.
- GEL High pressure gas discharge lamp
- ZT ignition transformer
- the Prevention of flashovers and for security reasons for supply the high pressure gas discharge lamp (GEL) is a two-core, special high-voltage-resistant line (HL), what needs along with others Measures for protective insulation of the control unit and the lamp connector or lamp base (LS) a not insignificant cost required.
- FIG. 3 also shows some means provided for radio interference suppression, namely two radio interference suppression chokes (D1, D2) connected symmetrically in the connecting lines to the high-pressure gas discharge lamp and a capacitor (C L ) connected in parallel with the high-pressure gas discharge lamp (GEL).
- D1, D2 radio interference suppression chokes
- C L capacitor
- the object of the invention is to provide a device that compared to the known device has a simpler and cheaper structure and can also be carried out on a small scale overall.
- the ignition device each an ignition transformer in the two connecting lines between the Control unit and the high pressure gas discharge lamp.
- the device according to the invention thus has two instead of one, Ignition transformers, which, however, means the two previously existing Radio interference suppression chokes can be saved because their interference suppression function the secondary coils of the ignition transformers are also taken over.
- the Both ignition transformers are significantly smaller, and also easier to execute than the ignition transformer in the device after State of the art, since each of the two ignition transformers only about half Must generate ignition voltage. Because the insulation effort of a transformer but growing significantly faster than the tension, everyone can two ignition transformers are particularly simple, small-sized and with little Isolation expenses are carried out.
- the two ignition transformers can even be practically used by the two radio interference suppression chokes known from the prior art Added a few additional primary turns be carried out. Since their construction volume is only insignificant enlarged, can thus in the device according to the invention compared to the known almost the volume of the previously used Ignition transformer can be saved.
- the two ignition transformers by adding some Wire windings from the radio interference suppression chokes originally required anyway emerge, the ignition transformers thus produced are compared to the previously used even much cheaper.
- this capacitor for the high-pressure gas discharge lamp to connect in parallel.
- this capacitor also causes the two to be balanced Ignition transformers generated ignition pulses.
- the ignition device in the lamp connector or in the Arrange lamp base Due to the structure of the invention Installation increases the required installation volume on the lamp connector or lamp base only slightly, while the control unit is significantly reduced in size can be.
- the ignition voltage is also in close proximity to the High-pressure gas discharge lamp is generated, lead the connecting lines to the control unit, the maximum open circuit voltage of the High pressure gas discharge lamp, which is one to two orders of magnitude below the ignition voltage.
- the connecting lines are therefore easy to isolate and therefore particularly inexpensive. It is also advantageous that the Measures for radio interference suppression and ignition voltage limitation can be limited to the lamp area, which the structure of the Control unit further simplified.
- a capacitor and / or a varistor can be provided. in the If the space in the lamp area is too limited, this can Components are also advantageously assigned to the control unit.
- Ignition energy to be fed can either be two the ignition transformers assigned ignition capacitors are provided or, if necessary, also a common ignition capacitor supplying both ignition transformers. Especially due to the available installation space to decide whether a (due to its higher capacity or Charging voltage) larger single ignition capacitor or two, but smaller, Ignition capacitors are cheaper. Of course, the ignition energy if necessary by connecting in parallel to a larger number of Capacitors are distributed.
- the discharge of the ignition capacitor (s) into the primary windings of the Ignition transformers advantageously take place through a switching spark gap, which ignites at a given voltage, as such Schalffunkenumble is particularly inexpensive and no external Control requires.
- FIGS 1 and 2 each show an embodiment of the invention Device for igniting and operating a high pressure gas discharge lamp in a motor vehicle.
- the circuitry structure of each is shown Ignition device and the high pressure gas discharge lamp (GEL), the circuit parts shown also spatially near the High pressure gas discharge lamp (GEL), for example in the lamp connector or in the Lamp base (not shown) are arranged.
- GEL high pressure gas discharge lamp
- the high pressure gas discharge lamp (GEL) is connected via two connecting lines (1, 2) connected to a control unit, not shown, in each Connection line (1, 2) each the secondary winding of an ignition transformer (ZT1, ZT2) is switched.
- V varistor
- C capacitor
- the primary windings of the ignition transformers (ZT1, ZT2) are (zünd C, C zünd1, C zünd2) with a ( Figure 2) or two (Figur1) firing capacitors connected, by means of a Schalffunkenumble (FS) as a switching element in the primary winding of the ignition transformers (ZT1 , ZT2) can be discharged.
- each ignition transformer (ZT1, ZT2) is assigned its own ignition capacitor (C ign1 , C ign2 ), whereas in FIG. 2 the charge of a single ignition capacitor (C ignite ) to both ignition transformers (ZT1, ZT2) ) is divided.
- the switching spark gap (FS) is in each case an acceleration capacitor (CB) connected in parallel, which is the gas discharge of the switching spark gap can run accelerated, whereby the generated on the secondary side Ignition voltages reach higher values.
- CB acceleration capacitor
- the Schalffunkenrange discharges the / the firing capacitors (C zünd, C zünd1, C zünd2) in the primary side windings of the ignition transformers (ZT1, ZT2).
- the ignition transformers (ZT1, ZT2) are switched so that the Add ignition voltages on the secondary side.
- the ignition voltage is that of Control unit fed into the connecting lines (1, 2) open-circuit voltage overlays and ignites the high pressure gas discharge lamp.
- the lamp capacitor (CL) parallel to the High pressure gas discharge lamp (GEL) also reduces the cause Lamp malfunctions during operation and also ensures a Synchronization of the two ignition voltages and thus for a correct phase Addition.
- a simplification of the connection to the control device can be provided by at least one of the feed lines (3, 4) to the ignition device with the Connecting lines (1, 2) is connected (not in Figures 1 and 2 shown).
- the number of Lines to the control unit can be reduced to three, each by one connection the operating voltage of the high pressure gas discharge lamp (GEL) and the Charging voltage of the ignition capacitor (s) to a common potential is placed.
- GEL high pressure gas discharge lamp
- s Charging voltage of the ignition capacitor
