Claim:
1. A light-emitting diode apparatus comprising: a support substrate; and a light-emitting diode array formed of multiple light-emitting diodes arranged in a two-dimensional matrix shape on the support substrate, the light-emitting diode array having 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 the plurality of composite control units include a first composite control unit and a second composite control unit disposed nearer to the light distribution center than the first composite control unit, 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 to the light distribution center, wherein the first composite control unit includes an outer first light emitting diode and an inner first light emitting diode, and the second composite control unit includes an outer second light emitting diode and an inner second light emitting diode, wherein the outer first light emitting diode, the inner first light emitting diode, the outer second light emitting diode and the inner second light emitting diode are aligned along a same direction, and wherein the inner first light emitting diode has a smaller area than that of the outer second light emitting diode.
