Definitions
- the invention relates to a method for igniting a high-pressure discharge lamp by means of an ignition device.
- the invention is based on a method for igniting a high-pressure discharge lamp by means of an ignition device with an ignition transformer according to the preamble of the main claim.
- the known ignition device has an ignition transformer, a starting capacitor and a spark gap as the ignition switch.
- the primary winding is maral ⁇ tet serially to the ignition capacitor and the spark gap.
- the secondary winding is connected in the current path of the high-pressure discharge lamp to be ignited.
- a charging voltage is applied in parallel to the ignition capacitor. If this exceeds the switching voltage of the spark gap, so this turns on and there is a short, high current ⁇ shock in the primary winding of the ignition transformer, which is up-converted and is applied via the secondary winding to the high-pressure discharge lamp. If the primary current falls below a certain value, the discharge arc in the spark gap goes out and this switches off again.
- the duty cycle is not optimal because the spark gap can not be actively switched off and conducts until the ignition current falls below a holding ⁇ threshold and the spark gap switches off. The Duty cycle is therefore significantly longer than the optimal Einsehaltdauer.
- the object is achieved according to the invention by a method for igniting a high-pressure discharge lamp by means of an ignition device having a starting capacitor, an ignition switch and an ignition transformer, characterized by the following steps taking place one behind the other:
- the fundamental frequency here is the fundamental frequency of the ignition switch current without higher-frequency vibrations. These high frequency oscillations can cause the current through the ignition switch to momentarily become zero before the fundamental of the ignition switch current becomes zero.
- the ignition switch is inventively actively ⁇ on and doing the duty cycle is so short ⁇ th held that the ignition switch is turned under power. With this measure, a higher ignition voltage can be achieved with greater repeatability.
- the ignition switch is opened at a switch-off time, which depends on the current voltage of the ignition capacitor. With this measure, a simpler control of the ignition switch is achieved.
- the switch-off time is in the voltage range of 60% of the positive charging voltage of
- Ignition capacitor up to 90% of the charging voltage of the Zündkon ⁇ capacitor which is achieved in the subsequent negative voltage maximum.
- the voltage generated when the switch opens can be higher than the voltage generated when the switch is closed.
- a meaningful area for the switch-off time points for a particular circuit arrangement can be during the development the circuit arrangement can be obtained by the following method:
- This method can also be carried out by the circuit arrangement during operation, if the ignition ⁇ voltage itself or a value correlating with the ignition voltage magnitude can be measured.
- the measurement of an absolute Zündnapssucc is not absolutely necessary, it is sufficient if the height of the ignition voltage can be measured relatively.
- the circuit arrangement preferably generates a plurality of ignition pulses by repeatedly closing and reopening the switch.
- the switch-off time point is particularly preferably varied within the meaningful switch-off range found above.
- the switch-off time is varied within the Ausschalt Symposium Editions until the high pressure discharge lamp has ignited, and this from ⁇ switching time is then stored to start during your next ⁇ th ignition phase with this switch-off.
- the circuit arrangement for igniting a high-pressure discharge lamp has an ignition transformer having a primary and a secondary winding, wherein the secondary winding is connected to the lamp to be ignited and the primary winding with an ignition switch, wherein the ignition switch is controllable to a through the primary winding of Ignition switch active current active, and the circuit arrangement executes the above method and the switch-off of the switch varies in a predetermined Be ⁇ rich.
- FIG. 1 shows a circuit arrangement with an ignition device which has a controlled switch which can carry out the method according to the invention
- Fig. 3 shows a first Zündpulsform invention
- Fig. 5 is a graph for the optimum
- FIG. 1 shows a circuit arrangement known per se for operating high-pressure discharge lamps which comprise a half-bridge lamp.
- Bridge with the series-connected half-bridge switches S2 and S3, at the center of a series circuit of a lamp inductor L3, the secondary winding L2 of a Zünd ⁇ transformer TR and a high-pressure discharge lamp 5 is connected.
- the free end of the high-pressure discharge lamp 5 is connected to the connection point of a series connection of two coupling capacitors C 1 and C 2.
- the half-bridge is connected in parallel with the series connection of the coupling capacitors.
- the supply voltage U_B (425V in this exemplary embodiment) is applied to this parallel circuit.
- the anode of the freewheeling diode and a connection of the ignition capacitor C3 are connected to the reference ⁇ potential of the supply voltage U_B.
- a charging resistor Rl for charging the ignition capacitor C3 is connected between the other terminal of the ignition capacitor C3 and the Ver ⁇ supply potential of the supply voltage U_B .
- a charging resistor Rl for charging the ignition capacitor C3 is connected. On this resistance of the ignition capacitor C3 is charged until the voltage applied to it a plausible ⁇ agreed charging voltage exceeds U_C3. If this is the case, then the ignition switch Sl is turned on at the time t 1, ie conducting, as shown in Fig. 2.
- a circuit current begins to flow through the components C3, LI and S1 / D2, and the circular current is transformed by the ignition transformer TR secondary side into an ignition voltage Uz.
- the ignition switch is turned off again.
- the voltage at the ignition capacitor C3 shows channel 1.
- Channel 2 shows the voltage at the ignition switch Sl, channel 3, the current ii through the primary winding LI of the ignition transformer TR.
- Channel 4 finally shows the ignition voltage Uz ⁇ whose maximum at about 3kV is OFF ignition pulse here.
- FIG. 3 shows an ignition pulse shape generated by the method according to the invention and the courses of relevant quantities.
- the ignition voltage at switch-off ignition pulse here is 5, 2kV.
- the optimal switch-off time lies in the time range in which the ignition capacitor C3 at its first discharge the voltage range of + 60% of the charging voltage until reaching 90% of the charging voltage of the subsequent negative voltage maximum (-90%), which would be achieved without actively switching off the ignition switch (see FIG.
- the charging voltage is the voltage applied to the ignition switch before switching on the ignition switch.
- the maximum is reached during Zündpulsdorf Power off ⁇ th of the ignition switch. This is called a switch-off ignition pulse.
- the amount of ignition voltage is higher than the ignition voltage when switching on the switch, which is called igniting pulse.
- a total particularly effective ignition pulse is also achieved insbeson ⁇ particular that an equally high or higher Ausschaltzündpuls is generated, which follows in Zündspan ⁇ tion course directly to the Einschaltzündpuls.
- the turn-on ignition pulse is about 4 kV
- the turn-off spark, as written above is about 5, 2 kV.
- the optimum time for switching off depends on the lamp cable length as well as on the cable capacitance and inductance.
- the lamp cable length, Jardinkapazi ⁇ ty and inductance vary depending on the application.
- the duty cycle of Zündschal ⁇ ters during the ignition phase of the electronic ballast is varied in a time range so that the optimal duration is swept for any in the application confi ⁇ guration.
- This method is particularly particularly advantageous with a microcontroller feasible.
- This can vary during the ignition phase the switch-off in a reasonable Be ⁇ rich, in order to generate a firing pulse of optimum height in each case.
- the switch-off time which are stored generated the highest firing pulse in order to meet to ⁇ future ignition phases with this switch-off time , The procedure can be repeated as needed or at regular intervals.
- FIG. 4a shows an ignition pulse generated by the method according to the invention and the courses of relevant variables for a switch-on duration of the ignition switch which is at the upper limit of the switch-on duration according to the invention.
- the naming of the relevant variables is the same as in Fig. 3.
- the Einschaltzündpuls here is approximately 4 kV, the off ⁇ schaltzündpuls at about 3, 6 kV.
- FIG. 4b shows the situation with a switch-on duration of the ignition switch which lies at the lower limit of the switch-on duration according to the invention.
- the naming of the relevant variables is the same as in Fig. 3.
- the turn ⁇ ignition pulse here is approximately 4 kV, the Ausschaltzündpuls at about 3, 3 kV.
- FIG. 5 shows the curves of FIG. 2 with a graphical representation of the optimal AuschhaltZeit Vietnameses invention of the ignition switch Sl.
