PROBLEM TO BE SOLVED: To suppress instability in startup, when supplying a cold cathode fluorescent lamp with current. SOLUTION: An electronic stabilizer circuit 10, connected in series with a power circuit of this cold cathode fluorescent lamp 12, has variable impedance Q1 which is automatically adjusted, depending on the magnitude of the lamp current, and as a result, the lamp current I<SB>L</SB>is limited to a certain current threshold.
