摘要:
PROBLEM TO BE SOLVED: To provide an LED driving circuit and an LED array device in which the number of LEDs employed can be reduced by directly employing an AC voltage.SOLUTION: A ladder network LED circuit of the present invention includes three first branches connected to one another by first middle junction points c1 and c2 between first and second junction points a and b, and three second branches connected to one another by second middle junction points d1 and d2 between the first and second junction points a and b. The LED circuit includes two middle branches connected between the first and second middle junction points c1 and d1, and c2 and d2 of an identical sequence. Here, LED devices 8, 9, 10, 11, 12, 13, 14, and 15 are disposed on the first and second branches and the middle branches, respectively.
