Definitions
- the invention is based on an input circuit for an ignition device of a high-pressure gas discharge lamp, which can be used in particular for use in headlights of motor vehicles, of the type defined in the preamble of claim 1.
- an ignition transformer is provided, the primary winding of which a voltage is supplied.
- the secondary winding transforms this voltage up to the voltage required to ignite the lamp.
- a capacitor is arranged in parallel with the series connection of the primary winding and a controllable switch, which is formed by a controlled thyristor. This capacitor is charged for ignition to an effective voltage which is then present at this point in time. at When a certain voltage is reached, the controllable switch is turned on and the capacitor is discharged.
- the input circuit designed according to the invention as a protective circuit for the ignition device enables the use of less expensive and possibly fewer components within the ignition device.
- the input circuit is arranged between the input terminals of the ignition device and consists of a capacitor or a protective element or the combination of a capacitor and a protective element, and protection for both the ignition device and for which forms the supply circuit supplying the supply voltage.
- the protective element is a varistor or a diac or a zener diode.
- a switching element with or without control is provided as a controllable switch.
- Control a thyristor, a transistor, a field effect transistor or a triggerable spark gap can be provided.
- a switching spark gap, a diac or a breakover diode can alternatively be provided as the switching element without activation.
- FIGURE shows a schematic block diagram of the input circuit of an ignition device designed according to the invention.
- FIG. 1 a block diagram of the input circuit of an ignition device designed according to the invention is shown schematically.
- a high-pressure gas discharge lamp 10 is on one side via a secondary winding 9
- Ignition transformer 11 connected to a first connection line 12 of a power supply circuit, not shown in detail.
- the high-pressure gas discharge lamp 10 is connected on its second side to a second connecting line 13 of the power supply circuit.
- Connection lines 12 and 13 have a supply voltage U.
- the high-pressure gas discharge lamp 10 is supplied with both combustion and ignition energy via these two connecting lines 12 and 13.
- the ignition energy is applied by the ignition device designed according to the invention with the aid of a pulse.
- the ignition transformer 11 is provided with a primary winding 7 and the secondary winding 9, which are closely coupled to one another.
- a controllable switch 6, a resistor 3 and a diode 4 are provided in series with the primary winding 7.
- the diode 4 can optionally also be omitted.
- a capacitor 5 is arranged in parallel with the series connection of primary winding 7 and controllable switch 6. This capacitor 5 is in series with the resistor 3 and the diode 4 between the
- Connection lines 12 and 13 is thus charged by the voltage U, which is supplied by the supply circuit, not shown.
- the controllable switch When a certain voltage is reached, the controllable switch is closed and thus suddenly conductive. In this way, the ignition pulse is generated and the current flow through the primary winding 7 is made possible.
- the voltage is determined and the control is carried out. H. for example the closing of the controllable switch 6 by a control circuit 8, to which the voltage at the capacitor 5 is supplied via a line.
- an input circuit for protection against excessive voltage peaks is provided between the connecting lines 12 and 13, which, seen from the supply circuit, represent the input of the ignition circuit.
- This input circuit consists of a capacitor L or a protective element 2 or a combination of a capacitor 1 and a protective element 2. This provides protection both for the ignition device and for the supply circuit supplying the supply voltage U.
- the protective element 2 can be a varistor or a diac or a zener diode.
- a switch element with or without control is possible as controllable switch 6.
- a control circuit 8 is provided in order to control the switch 6.
- a thyristor, a transistor, a field effect Transistor or a triggerable spark gap can be provided.
- a switching spark gap, a diac or a breakover diode can be used as the switching element without control.
- the function of the ignition circuit is as follows.
- an increased DC voltage U is applied to the connecting lines 12 and 13.
- the capacitor 5 is charged via the resistor 3 and the diode 4.
- the controllable switch 6 is closed by the control circuit 8 when a certain voltage is reached.
- the capacitor 5 discharges into the primary winding 7.
- the value of this pulse which has been transformed up by the secondary winding 9 in accordance with the transmission ratio, is delivered to the high-pressure gas discharge lamp 10 in order to ignite it.
- both the ignition circuit and the supply circuit supplying the supply voltage U on the connecting lines 12 and 13 are protected against excessively high voltage peaks.
- cheaper components can be used due to the lower demands on their dielectric strength and possibly also a smaller number of components overall for the ignition device.
