Abstract
Additional reactance device adaptable to pre-heated gas discharge lamps especially for fluorescent tubes, with a heating circuit that, in addition to the lamp electrodes, contains a controlled electronic switch, characterized by the fact that in the heating circuit The secondary winding (8) of an autotransformer (8, 9) is arranged at the same time as the electronic switch (3) is connected in parallel with a serial circuit, which consists of at least the primary winding (9) of the autotransformer and a capacitor (23), in which the capacitor is discharged through the primary winding (9) of the autotransformer when the switch is on, so that the autotransformer generates priming voltage pulses, caused by a control circuit (26 to 38), connected to the electrodes (4, 5) of the lamp, whose output is connected to the control electrode (40) of the electronic switch (3), and in which a c voltage divider circuit with a timer (30, 36) to produce a time delay, equivalent to the preheating time necessary for the electrodes (4, 5) of the lamp, obtained by a displacement of the connection point of the electronic switch (3) approximately proportional to the temperature of the electrodes (4, 5) of the lamp and between a small phase angle of the voltage and a phase angle located in a voltage limit value comprised in a zone of the peak value of the voltage, at the same time that the electronic switch (3) is blocked after exceeding this limit value and due to the fact that the timer is associated with means (31) that, when the switch (3) is blocked, degrade the magnitude dependent on the time with a speed higher than that corresponding to the cooling speed of the electrodes without load of the lamp, so that the switch (3) is turned on repeatedly after several times iodines of the mains voltage, producing isolated priming voltage pulses.
