    • PURPOSE: An electric stabilizer is provided to minimize unnecessary consumption power by connecting a dc 300-V voltage from the stabilizer in parallel with a piezoelectric actuator so as to be used as a driving source. CONSTITUTION: An electric stabilizer comprises a piezoelectric actuator(20) whose end displacement occurs at applying a voltage. A disk plate spring(43) is installed in a cylinder(42), and a curved surface of the disk plate spring(43) directs the piezoelectric actuator(20). An insulating guide pin(44) is contacted with a center of the curved surface of the disk plate spring(43) and with a displacement generation end of the piezoelectric actuator(20). An elastic spring(65) forces an elastic force to the piezoelectric actuator(20) in an opposite direction of the insulating guide plate(44). A dc voltage is applied to the piezoelectric actuator(20), and points of contact(61,62) are connected in series to filament terminals(13,15) of a fluorescent lamp.
