A light-emitting diode apparatus includes a support substrate; and a light-emitting diode array formed of multiple light-emitting diodes arranged two-dimensionally on the support substrate, constituting a light distribution center having a highest brightness in the light-emitting diode array, wherein the multiple light-emitting diodes are divided into a plurality of control units, drive currents of which can be individually controlled, wherein the plurality of control units include a plurality of composite control units in each of which a plurality of light-emitting diodes are connected in series, and wherein among the plurality of light-emitting diodes in each of the composite control units, a light-emitting diode which is positioned farther from the light distribution center has a larger light-emitting area than that of a light-emitting diode which is positioned nearer from the light distribution center.
