Abstract:
Proposed is a circuit for driving a fluorescent lamp and a light-emitting diode. The circuit may include an inverter; a fluorescent lamp driving branch for driving a fluorescent lamp; a light-emitting diode driving branch for driving a light-emitting diode; a starting branch; and an alternate control branch. By using a simple circuit structure, various embodiments may realize a circuit capable of conveniently and alternately driving a fluorescent lamp and a light-emitting diode.
