Who uses these lamps, is well aware of their shortcomings. Like and light nice and light, and switch, and pressure on the ears buzz - it works choke. Yes and they don't light up at once, and yet will turn on the starter, which, alas, unreliable, and most importantly - and in these lamps have a filament, and if she will burn out, the lamp has to be replaced with a new one.
The figure shows a scheme that allows not only to eliminate pesky shortcomings, but also to revive the lamp burned coils.
We explain the scheme. Capacitors C1, C4 should be a paper, with an operating voltage 1.5 times the supply voltage. Capacitors C2,it is advisable to take NW mica. The resistor R1 wire definitely, handpicked by capacity lamp used.
Diodes VD2, VD3 and capacitors C1, C4 constitute a full-wave the rectifier voltage doubler. The values of capacitances C1, C4 single working lamp voltage L1 (the larger the capacity, the greater the voltage on the electrodes). In the moment of switching the voltage at points a and b is 600 V. But when you fire it decreases and ensures the normal operation mode.
These elements of the scheme depending on the power of fluorescent lamps are shown in table:
