12 Volt Fluorescent
Lamp Drivers
A typical fluorescent lamp is basically a glass tube, filled
with low pressure mercury vapor and a mix of additional gases, and having a
filament at each end. The glass tube is internally coated with fluorescent
salts. In use, an arc forms in the tube, the mercury emits ultraviolet light,
this excites the fluorescent substances, which in turn produce visible light.
The exact color of the light depends on the mix of different fluorescent
substances used |

Self Oscillating 25W CFL Lamp Circuit A description is given of a self
oscillating CFL circuit (demo board PR39922), which is able to drive a standard
Osram Dulux T/E GX24q-3 lamp or similar lamp types with a nominal lamp power of
26 W. However, the lamp power is fixed at about 22 W so that the total power
drawn from the mains is about 25 W or less. The circuit is based on a Voltage
Fed Half Bridge Inverter topology. It is designed for a nominal mains voltage of
230 Vrms where instant-start is applied for instant light output. The Half
Bridge switching devices are the bipolar power switching transistors of type
