Simple Cold Cathode Fluorescent Lamp Supply Wiring diagram Schematic
Simple Cold-Cathode Fluorescent-Lamp Supply Circuit Diagram. For back-lit LCD displays, this supply will drive a lamp. LT1072 drives Ql and Q2, and a sine wave appears across CI. LI is a transformer that steps up this voltage to about 1400 V. Dl and D2 detect lamp current and form a feedback loop to the LT1072 to control lamp brightness. C1 = MUST BE A LOW LOSS CAPACITOR. METALIZED POLYCARB WIMA FPK 2 (GERMAN) RECOMMENDED. L1 = SUMIDA 6345-020 OR COILTRONIX CTX110092-1. PIN NUMBERS SHOWN FOR COILTRONIX UNIT. L2 = COILTRONIX CTX300-4 * = 1 % FILM RESISTOR.

4W Fluorescent lamp driver
This is a 4W fluorescent lamp driver.we can operate this with 12 v battery.so I suppose you can attach this one for your vehicle even. on the other hand you can use this one as an emergency lamp.so try on this be creative to get the maximum harvest.
Notes.
* Assemble the schema on a general purpose PCB.
* The IC 1 must be mounted on a holder.
* Use heat sink for transistor Q1.
* Use a 3 V primary , 230 V secondary, 5W transformer for T1.
* Power the schema from a 12V battery or 12V DC power supply.
* The L1 can be a 6 inch, 4W fluorescent lamp.
