- the omission of the L connection at the ignition circuit arrangement according to the invention makes it possible to save a line, for example between a distribution cabinet in which the supply choke is arranged and a floodlight pole on which the lamps and the associated ignition circuit arrangement are arranged.
- ... after the ignition of the lamp denotes a period or a time at which the gas discharge in the lamp is started at least in a partial region of the gas volume, moreover, an ignition situation in which the lamp Although the gas discharge is still relatively ignited, the gas discharge is still comparatively unstable and thus there is a risk that it will again extinguish the discharge
- the ignition process with the ignition device according to the invention is finished only insofar as the gas discharge burns stably and thus there is no danger of the discharge being extinguished
- the ignition circuit arrangement according to the invention can also be stabilized during the transition phase until the gas discharge burns stably by generating additional ignition pulses Zündschal-
- an AC supply variable of the lamp is formed over several periods of the AC supply variable after ignition of the lamp, these ignition pulses can also be tuned during the described transition phase from a partial discharge to a stable discharge on the time profile of the AC supply variable the lamp are generated.
- This transition phase within which the replication of the phase characteristic of the AC supply variable takes place, can be adapted to the respective circumstances.
- the ignition circuit arrangement according to the invention may be advantageously designed, depending on the embodiment, to simulate the phase characteristic of the AC supply variable of the lamp for up to 5, 10, 15, 20 or 30 periods or even more periods of the AC supply variable after the partial ignition of the discharge.

- This converter circuit may expediently be set up to convert the mains voltage applied before the lamp is lit as well as the voltage applied after ignition, which is dependent on the lamp operation, to a predetermined, constant supply voltage of the control device.
- the throttle to support the ignition additional electrical Energy may be expedient if the second switch is driven to close after the ignition of the lamp, when the simulated AC power supply reaches about the zero crossing and is then driven to open again before the expiration of a quarter period. It is particularly useful if 10 to 20 degrees before or after reaching the zero crossing of the second switch for closing, most suitably 0 to 10 degrees before or after reaching the zero crossing of the second switch is driven to close. Ideally, the second switch is triggered after closing the lamp to close about 0 to 5 degrees before or after reaching the zero crossing. The control of the switch is therefore synchronized with the replicated AC supply variable, for example with the simulated mains voltage.
- the second switch is triggered after opening the lamp for several periods in the region of the zero crossing of the simulated AC supply quantity for closing and before the expiration of a quarter period to open.

In this period, in which the supply voltage of the lamp can not be measured by the ignitor according to the invention, it is nevertheless ensured that the control of the ignition can be synchronized with the supply voltage of the lamp, ie with the mains voltage.
- the ignition circuit arrangement according to the invention can have exactly two input terminals to be connected to different input potentials, which can be dispensed with in the case of conventional ignition circuit arrangements.
- the ignition circuit arrangement according to the invention also has only two output-side connections, to which the lamp can be connected.
- the invention solves the above object with a method for igniting a gas discharge lamp having the features of claim 10.
- the inventive method is characterized in that the ignition circuit is connected on the supply side between the inductor and the lamp, wherein after the ignition of the lamp, the phase characteristic an alternating current supply variable, in particular the alternating voltage applied to the supply circuit is simulated, for example, zero crossings of the alternating current supply quantity are determined and the timing of the ignition process is controlled as a function of the simulated phase curve of the alternating current supply variable.
- the temporal course of the alternating current supply variable is according to the invention in particular simulated such times, in which the discharge of the lamp already started, but not yet formed completely and stable.
- the time profile of an AC supply variable of the lamp such as the mains voltage, can not be tapped off in the supply circuit between the choke and the lamp, which is compensated for by the replica of the phase characteristic of the alternating current supply variable of the lamp according to the invention.
- the generation of an ignition pulse may be synchronized with the replicated AC supply voltage, such that the ignition pulse is generated when the instantaneous value of the supply voltage is above the lamp burn voltage.
- the method according to the invention adapts automatically to the respective frequency of the supply network of the discharge lamp.
- the frequency of the AC supply voltage is sampled before the lamp is ignited.
- This scanning can be carried out before the ignition of the lamp at a measuring point which is provided between the mutually arranged in series choke and the lamp, since then no lamp current flows and inasmuch as the sine of the supply frequency genuine supply side can be scanned behind the throttle.
- the supply voltage between see lamp and throttle can be tapped, so that the otherwise necessary L-line between the Zündsceuticsan emblem and the supply throttle accommodating distribution cabinet can be omitted.
- the sampled phase position of the alternating Ström supply in particular the AC supply voltage and the sampled frequency can be used to simulate the AC supply size, so that this replica is then available to control the timing of the ignition process.

- synchronizing generally refers to the timing of operations in chronological order, For example, it may be expedient if, in order to assist the ignition process before the generation of an ignition pulse, a throttle arranged in the supply circuit is charged to the lamp and at least In this case, the start or the end of the charging of the throttle is expediently adapted to the simulated course of the alternating current supply variable or synchronized with it if a charging path for the choke is switched after the lamp has been ignited, if the instantaneous value of the simulated Power supply variable reaches a predetermined value, in particular the value zero, and is opened again within a quarter period.
- charging an input power source for an ignition trigger circuit of the ignition circuit may be timed to synchronize with the replicated phase response of the lamp's AC supply. This process must in each case take place before triggering an ignition pulse, the charging of the input energy source of the triggering circuit according to the invention occurring at those times at which the energy provided by the supply is not completely necessary for the burning operation of the lamp. This avoids that the lamp is accidentally deleted by charging the input power source whose energy is also taken from the supply circuit of the lamp.
- this predetermined threshold value corresponds to a value which adjusts to the network or the throttle in the case of faulty wiring of the ignition circuit arrangement according to the invention.
- Such a wiring fault exists, for example, if the phase connection, ie the B connection of the ignition circuit is not connected to the output of the choke, but directly to the mains voltage (L). The then missing throttle in the supply circuit of the lamp is made by an increased bridge current noticeable, whose detection leads to the blocking of the Zündscriens- arrangement. It is particularly expedient if the switchable current path is identical to the above-mentioned, switchable current path for charging the inductor, ie, a switch releasing the current path can be used according to the invention for both functions.

- the input side it has the input terminals B, N on.
- the lamp inductor 10 is connected in the described embodiment outside of the ignitor between the input terminal L of the AC power supply and the input terminal B of the ignition device 1.
- the ignitor 1 again has two terminals LP, N, to which the lamp 3 is connected.
- the ignition circuit arrangement comprises an ignition transformer 20, which with its primary winding 21 is part of a triggering circuit which has as essential components a controllable rectifier 31 as an input energy source, the primary-side coil 21 and the switch 40. Both the input power source 31 and the switch 40 are driven by a controller 50 by means of the control lines ST1 and ST2. The controller 50 adjusts the output of the input power source 31 and initiates the generation of a pulse in the trigger circuit by closing the switch 40.
- the primary-side coil winding 21 is coupled via the ignition transformer 23 to the secondary-side coil winding 22, which serves for the transmission and transformation of the pulse and is connected in series with the lamp and the throttle 10. Accordingly, the supply circuit of the lamp in the described embodiment comprises the series connection of the choke 10, the secondary-side coil winding 22 and the lamp itself.
- the input energy source 31 of the triggering circuit is coupled to the input B of the ignition unit 1, ie to the output of the throttle 10.
- the input power source for the triggering circuit (31, 21, 40) designed as a controllable rectifier 31 is dimensioned such that that it can provide the necessary energy to generate the ignition pulse.
- the inverter 32 is connected to the input B of the ignition circuit, which provides the operating supply to the controller 50.
- the controller 50 samples the instantaneous voltage at the terminal B with the sensor line SL1 between the choke 10 and the lamp, in the described embodiment at the terminal B and with the sensor line SL2 the instantaneous current, for example the flowing lamp current IL, after the lamp has ignited.
- the ignition circuit arrangement shown in FIG. 2 has a current path (V3, V4) bridging the lamp 3, with which the inductor 10 can be charged independently of the lamp and the triggering circuit by actuation of the switch 61 by means of the mains voltage U n .
- the controller 50 is connected via the control output ST3 to the gate of the switch 61.
- a parallel circuit of a capacitor C3 is provided to the lamp 3, which serves as a high-frequency scrub gleichkondensator adopted so as not to burden the throttle 10 with the Hoch Stammszündimpuls.
- the capacitor C3 prior to ignition and charge of the reactor 10, a portion of the energy stored therein is transferred to the capacitor C3, this additional energy serving to assist in building up the discharge in the lamp 3 during the ignition process.
- both the controller 50 and the input energy source 31 of the trigger circuit are not operated directly via the mains supply voltage L, but via a terminal in the supply circuit of the lamp, which is arranged between the choke 10 and the lamp 3.
- This connection is arranged in the described embodiment at the outlet of the throttle 10, which is directed to the lamp 3.
- the potential present at this output is used according to the invention for the electrical supply of the ignition Circuit arrangement used.
- the mains voltage or its phase position can only be scanned via the sensor line SL1 as long as the lamp 3 has not yet been ignited. After ignition, SLl essentially detects the lamp voltage of the discharge lamp. To control the entire ignition process, however, information about the phase position of the mains voltage is required, in particular information about the zero crossing of the mains voltage. For this purpose, in the described embodiment of the invention, the controller 50 simulates the phase position of the supply voltage.
- the mains frequency is first sampled by the controller via the line SL1 and an internal frequency generator of the controller 50 is operated at the detected mains frequency before the lamp is ignited. This is followed by a synchronization of the internal, simulated supply change variable with the mains voltage sampled via the sensor line SL1.
- the mains voltage U n for example a sinusoidal alternating voltage of 50 Hz, is simulated fully synchronously in the controller 50, so that the internal frequency generator emits a corresponding 50 Hz sine-frequency oscillation, which coincides with the system oscillation at each instant.
- the lamp inductor 10 is charged for a predetermined period of time and thus with a predetermined electrical energy by activating the switch 61 to close the charging path (10, V3, 61).
- the controller 50 controls the gate of the switch 61 via the control line ST3.
- a charging current flows via the switch 61 into the throttle 10, which absorbs energy.
- the switch 61 is opened again. Subsequently, the capacitor C3 can be charged via the mains and the energy previously stored in the reactor 10.
- the timing of the charge of the throttle 10 over the Charging path by means of the switch 61 and the subsequent charge of the storage capacitor C3 takes place synchronously, ie in timed relationship with the network voltage U n mimicked in the controller 50.
- the one-time close and open switch 40 is turned on and off again for a period of about one microsecond.
- the converter 31, which operates as an input energy source for the ignition triggering circuit, drives the ignition triggering circuit via the primary-side coil winding 21 of the ignition transformer 20, whereby a primary-side pulse is generated.
- the magnetization of the primary-side coil winding is transformed via the Zündübertragerkern 23 to the secondary-side coil winding 22 with the transmission ratio of the Zündübertragers and superimposed on the mains voltage as the ignition pulse.
- a secondary-side pulse is thus applied to the lamp 3, so that it can ignite.
- the ignition circuit arrangement in the case of the ignition circuit arrangement according to the invention, it is also readily possible to generate a plurality of individual primary-side pulses timed to match the AC supply variable reproduced in the controller 50 in order to facilitate the ignition process of the lamp 3. It is possible, for example, to generate a plurality of ignition pulses within a half-period of the simulated mains voltage or to generate a plurality of ignition pulses within successive periods of the alternating current supply variable simulated in the controller 50. Such a procedure is particularly advantageous when the first ignition pulse has only produced a partial ionization of the gas of the discharge lamp 3, but not yet a complete or stable discharge.
- further ignition pulses may be generated over a period of 3, 5, 10, 20 or even more periods after the partial ionization of the gas of the discharge lamp, timed to the simulated AC supply variable, in order to stabilize the discharge.
- the energy which is additionally available for the discharge during the ignition process can be set via the controller 50.
- the different firing parameters are very accurately adjustable as a function of the connected lamp, which in turn allows a safe ignition of the lamp with the lowest possible energy and thus circuit complexity, regardless of whether the lamp is cold or hot to ignite.
- the igniter can be designed so that the controller detects when hot ignition is necessary and then sets ignition parameters such as the switching times of the two switches 40, 61, the number of primary-side pulses, the level of the input voltage of the trigger circuit, etc, a.
- the ignition circuit arrangement illustrated in FIG. 2 is designed to generate ignition pulses within a positive half cycle of the supply voltage U N.
- ignition pulses are generated to successive and adjacent half-waves of the replicated supply voltage.
- the ignition process can be further improved by driving the second switch 61 to close after the lamp is ignited, when the mapped AC supply reaches approximately zero crossing and thereafter, before a quarter period has elapsed, the switch 61 is opened again to open.
- the energy which is available for starting or maintaining the discharge process in the lamp 3 can be increased, so that ultimately the setting of the discharge is simplified even under adverse conditions.
- this process can also be carried out over several periods of the supply voltage simulated in the controller, ie the activation of the switch 61 to close when the replicated variable reaches about the zero crossing and then to open before the expiration of a quarter period.
- the timing of the ignition phase is synchronized with the simulated in the controller 50 the supply voltage U N according to the invention, ie, the timing is adjusted to the reproduced alternating quantity, so that the ignition circuit according to the invention does not require an L input.
- FIG. 3 shows an oscillogram of the lamp voltage (CH 2) which can be tapped off at point B, see FIG. 2, and the AC supply variable (CH 1) mimicked in the controller 50, which corresponds to the mains voltage U N.
- the simulated AC supply variable (CH 1) was synchronized with the mains voltage U N.
- Tl run the simulated AC supply variable and the voltage sampled at B synchronously, ie the lamp 3 does not burn in this period.
- the period T2 describes the actual ignition process.
- a period of many network periods is necessary until the lamp stably burns at the end of T2.
- the switches 40, 61 of the ignition circuit according to the invention for adjusting the discharge synchronously, ie timed with the simulated in the controller 50 supply voltage to generate a plurality of firing pulses on the one hand and on the other hand by means of the throttle during the generation of these firing pulses each more energy for to provide the lamp to assist in the ignition process.
- the period T2 which comprises more than 30 periods of the mains voltage in the example given, a stable lamp discharge has built up so that the ignition circuit according to the invention can be switched off with the completion of the ignition process.
- the controller 50 controls the rectifier 31 via the control signal ST2.
- B Wegstrom measured via the current measuring means 80 and the ignition circuit 1 blocks when the detected bridge current in the bridging current exceeds a predetermined threshold.
- This predetermined threshold is set when the B-terminal of the ignition circuit is not connected to the output of the throttle 10, but directly to the mains voltage (L).
- the absence of the reactor 10 in the supply circuit of the lamp 3 is noticeable by an increased bridge current, after the detection of which the ignition circuit is blocked by the controller 50, so that no ignition pulses are generated.
- the current path (V3, V4) is connected to the switch 61, which is also used to charge the throttle 10.
