Rangkaian 12VDC Fluorescent Lamp Driver

Whenever there is a need for battery-powered lighting, like for camping, solar powered cottages, cars, boats, planes, or emergency purposes, fluorescent lamps have a great appeal. Firstly, they are very much more efficient than glow lamps, so they produce much more light for less power consumption. Secondly, their light color stays constant while the battery runs down.

In this article I will offer driver circuit for 12 V/5Watt fluorescent lamp, this circuit used a normal 220 to 10V stepdown transformer in reverse to step 12V to about 240V to drive a lamp without the need to warm the filaments.

  • Q1 (IRF510 MOSFET) must be installed on a heat sink
  • Dangerous ...!! Please be careful, This series contains 220 VAC that can sting you.

The IC1 TLC 555 is wired as an astable multivibrator for producing the necessary oscillations.The MOSFET Q1 is used to amplify the oscillations produced by the IC1.The out put of MOSFET is connected to the primary of the step up transformer to produce a ~240 V AC for driving the florescent lamp.

List Component:
  • C1 100uf /25V Electrolytic Capacitor
  • C2,C3 100nf Ceramic Capacitor
