Abstract

A light emitting module according to an exemplary embodiment of the present invention includes a printed circuit board (PCB) and first through m-th lighting blocks ('m' is an integer greater than one). The PCB has wiring patterns electrically connecting optical semiconductor devices. The first through the m-th lighting blocks are disposed on the PCB and configured to generate light. Each of the first through the m-th lighting blocks includes first through n-th lighting groups (each block includes at least one group), each of which includes optical semiconductor devices disposed on the PCB, and an electric currents configured to flow through each lighting group is substantially the same.
