Abstract

Disclosed are a light-emitting diode driving circuit and a fluorescent lamp including the same. According to one embodiment of the present invention, a light-emitting diode driving circuit comprises: a light-emitting diode array unit in which a plurality of light-emitting diodes are connected in serial or in parallel; a constant current control unit which is connected in parallel to the light-emitting diode array unit; and a capacitive element which is connected in parallel to the light-emitting diode array unit. Accordingly, it is possible to provide a fluorescent lamp which maintains a constant current characteristic regardless of the types of electronic ballasts.
