Light emitting diode driving circuit and light emitting diode array device

An AC driven light emitting device comprising:

• a plurality of first LEDs, each having a first polarity and a second polarity, linearly connected by (n) number of first middle junction points, in which the same polarities of adjacent first LEDs are connected each other, where n denotes an integer satisfying n≧2;
• a plurality of second LEDs, each having a first polarity and a second polarity, linearly connected by (n) number of second middle junctions, in which the same polarities of adjacent second LEDs are connected each other;
• a first junction point in which different polarities of the first LED of the first LEDs and the first LED of the second LEDs are connected each other;
• a second junction point in which different polarities of the last LED of the first LEDs and the last LED of the second LEDs are connected each other;
• and
• a plurality of third LEDs, each having a first polarity and a second polarity, connected between the first and second middle junction points in the same order such that the associated polarity of the third LED is connected to the middle junction point having the different polarity,
• wherein upon applying an alternating voltage between the first and second junction points, the first and second LEDs are driven in a half cycle of the alternating voltage and the third LEDs are driven in an entire cycle of the alternating voltage.
