发明名称 Method and circuit arrangement for producing an ignition voltage for fluorescent lamps
摘要 The invention, which relates to a method for generating a starting voltage for a fluorescent lamp, in which the starting voltage is generated by means of alternating voltage that is impressed on an LC series resonant circuit, and to a corresponding circuit arrangement, is based on the object of increasing the reliability of starting and avoiding maximum permissible starting voltages being exceeded. According to the invention, this object is solved in that the frequency of the alternating-voltage generator can be controlled by a control unit and in that a measuring circuit is connected to the control unit, whereby the alternating voltage can be gradually reduced from a high frequency to a lower frequency, where the lamp voltage is compared to a setpoint value at certain intervals and the starting procedure terminated when the setpoint value is reached.
