The present invention is directed to providing an LED driving circuit that can be reduced in size and produced at low cost, and that can effectively prevent a shoot-through current that may flow between a plurality of LED arrays. The LED driving circuit includes a rectifier, a first LED array containing a plurality of LEDs, a second LED array containing a plurality of LEDs; a connection unit for connecting the first and second LED arrays in series relative to the rectifier or for connecting the first and second LED arrays in parallel relative to the rectifier, a control unit for switching the connection of the first and second LED arrays relative to the rectifier from parallel to series by controlling the connection unit, and a reverse current preventing diode disposed between the first LED array and the second LED array. |
