Electronic circuit of initiation and operation of fluorine and PL lamps with energy saving that consist of an electronic filter (2) that includes combination of capacitors C1,C2 and inductors L1,L2, a "bridge" IC1 (3) of transformation of current from alternate to continuous, a capacitor C3 (4) for the stabilisation of oscillation that produces the "bridge" and a resistance R1 (5) via which the required drop of voltage becomes in order that with the suitable filters, the capacitors C4,C5 (6) becomes constant from stabilizer IC2 (7). The constant current that has resulted from the stabilizer (7) passes through the oscillator (8) that is a high frequency generator and contains resistance R4 for the regulation of the voltage that enters in the transistor (9) and the capacitor C6 for the regulation of transistor operation frequency (9). The transitor input voltage is regulated by resistance R5 (15) while the corresponding output voltage is regulated by resistance R6 (16). The transformed current at normal operation of the lamp is led to the electronic transformer T1, which has three threads, one primary P1 and two secondary S1 and S2. Threads P1 and S1 constitute parts of the superior (10) and the secondary (11) circuit respectively. The superior circuit (10) raise inductively the secondary (11) under normal lamp operation (12). The thread S2 is part of the control circuit (14) that controls the operation of the main circuit (10). |
