Cold-Cathode Fluorescent Lamp circuits

12V Fluoro Inverter

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

DC/ AC Inverter Unit for Liquid Crystal Display (LCD) Panel Currently, the most commonly used light emitting device is a fluorescent tube called a cold cathode tube or CCFL. The CCFL is called a cold cathode tube because even though the principle of illumination is the same as that of the hot cathode tubes used by indoor lamps, this lamp does not require preheating of the filament. Also, the electrodes at the end of the bulb stay at a low temperature while emitting light

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 BUJ101AU, pdf file
