PURPOSE: A bidirectional electric LED driver circuit is provided to supply electric energy, which is divided from both ends of a second impedance, to a bidirectional electric conductive LED set by connecting the set to both ends of the second impedance in parallel. CONSTITUTION: A uni-directional LED driver circuit(U100) comprises a first impedance(Z101), a second impedance(Z102), a rectifying device, and a bidirectional electric conductive LED set(L100). The first impedance and at least one second impedance are serially connected to each other. The bidirectional electric conductive LED set comprises at least one first LED and at least one second LED.
