    • There is provided an LED driving circuit. The LED driving circuit according to an aspect of the invention may include: at least one ladder circuit including: (n−1) number (here, n is a positive integer satisfying n≧2) of first branches provided between first and second junction points, and connected in-line with each other by n number of first middle junction points, (n−1) number of second branches arranged in parallel with the first branches, and connected in-line with each other by n number of second middle junction points between the first and second junction points, and n number of middle branches connecting m-th first and second middle junction points to each other, wherein at least one LED device is disposed on each of the first, second, and middle branches. Here, the number of LED devices included in each of the first and second branches is greater than the number of LED devices included in each of the middle branches.
    • 提供了LED驱动电路。 根据本发明的一个方面的LED驱动电路可以包括:至少一个梯形电路,包括:设置在第一和第二结之间的第一分支的(n-1)个数(这里,n是满足n> = 2的正整数) 点,并且通过n个第一中间连接点彼此并排连接,(n-1)个与第一分支平行布置的第二分支,并且彼此连接成n个第二中间 第一和第二接合点之间的接合点以及将第m个第一和第二中间接合点彼此连接的n个中间分支,其中至少一个LED器件设置在第一,第二和中间分支中的每一个上。 这里,包括在第一和第二分支中的每个中的LED装置的数量大于包括在每个中间分支中的LED装置的数量。
