Fluorescent lamp driver Circuit Diagram
Construction and Working
This circuit is constructed with timer IC555 as pulse driver for
fluorescent light, the timer IC is configured as multi-vibrator by the
timing resistros R1, VR1 and capacitor C1. Output switching pulse is
taken from pin 3, this pulse duration can be varied by varying VR1
resistor.
The transistor BD243C acts as switching trnasistor, here stepdown
transforer (0-3V) is used to drive 4 watts fluorescent lamp. The lamp is
connected at the primary winding, switching circuit is connected at the
secondary winding, by the switching pulse EMF is produced at secondary
winding this EMF induces primary winding hence by stepup process high
voltage is produced at primary, this is enough to drive 4 watts
fluorescent lamp by connecting battery and charger circuit we can use it
as emergency light.
