摘要： PURPOSE: An electronic ballast type LED fluorescent lamp is provided to extend the lifetime of an LED by arranging a plurality of LEDs in series or parallel. CONSTITUTION: An overcurrent blocking unit(101) is comprised of a pair of fuses and blocks the overcurrent over a preset value. An inductor of a filament unit(102) is connected to an output terminal of the pair of fuses. An impedance matching unit(103) matches the output impedance of the electronic ballast with the input impedance of the LED fluorescent lamp. The inductor of the impedance matching unit is connected to both ends of the inductor of the filament unit. A DC rectifier(104) converts input AC driving power into DC driving power. A DC constant voltage generating unit(105) charges and discharges the DC driving power converted by the DC rectifier.
