Summary of the invention
Therefore, the objective of the invention is circuit element in shell spatial placement and hold aspect this stack igniter is improved.
These purposes are that the feature by independent claims realizes.Dependent claims has further expanded central concept of the present invention in particularly advantageous mode.
According to a first aspect of the invention, a kind of stack igniter that is used for discharge lamp has been proposed.Thus, charging circuit charges at least one capacitor (pulse capacitor).
Be provided with a transformer, this transformer has elementary winding that is connected in parallel with described capacitor and the secondary winding that separates with described elementary winding, described secondary winding is connected between power line with voltage and the described lamp, and the energy that is stored in described at least one capacitor can be from described elementary winding coupled to described secondary winding.
Attenuator is connected in series between power line with voltage and capacitor that is connected in parallel and the elementary winding.Described attenuator suppresses the high-frequency current by described at least one capacitor, so that it is protected.
Described attenuator is corresponding to the resistance R of the prior art 2 according to Fig. 6, yet it is connected to different lines rather than is connected to the charging resistor of pulse capacitor now, promptly is connected on the line not with voltage of voltage supply.The same with the situation of prior art, if High-frequency Interference is coupled from described lamp, then this ohm and/or inductance attenuator also are used for according to the present invention this is responded, and make less than the described capacitor of flowing through from the too high high-frequency current of electromagnetic ballast.
As described below, make described attenuator be connected to the different terminals of supply voltage now by reconfiguring of circuit, rather than be connected to the charging circuit of described pulse capacitor, can obtain the particularly advantageous spatial distribution of described circuit.
Therefore, compare with other known configurations, be not configured to autotransformer according to pulse transformer of the present invention but have two independently windings, these windings for example can be made by the line of different materials and/or different-diameter, and making can be free more in the design of circuit.
According to attenuator of the present invention can be Ohmic resistance and/or inductance.
Charging circuit also has at least one Ohmic resistance usually.
The resistance of charging circuit can be connected in parallel with the igniting auxiliary capacitor thus.
Described attenuator can have ohmic resistor, and its resistance value is more much lower than the resistance value of described charging resistor.
The resistance value of the ohmic resistor of described attenuator for example can be less than 1kOhm, and preferably less than 200Ohm, this is far below the accepted value of charging resistor.
Described charging resistor can be connected to power line not with voltage.
In this case, therefore the charging resistor of described attenuator is connected to two different terminals with Ohmic resistance, promptly be connected to power line not with voltage on the one hand and be connected to power line with voltage on the other hand, this provides the particularly advantageous spatial distribution of these elements in the circuit.
The invention still further relates to the shell of the igniter that is used to superpose, wherein, described shell has tapered profiles in the time view.This tapered profiles is favourable in order to carry out the demoulding when the injection molding of plastic casing for example.In addition, the upside of shell is provided with leveling web (Nivellierungssteg), and this leveling web extends perpendicular to the inclined-plane of described taper, and the upside of this leveling web has formed the plane parallel with the bottom surface of this shell with the highest side of all the other upsides of this shell.
