1. An apparatus, comprising:
a plurality of light-emitting diodes (LEDs) arranged as an LED array,
the plurality of LEDs being distributed between a central group of LEDs and a border group of LEDs that surrounds the central group of LEDs,
the central group of LEDs being arranged in a two-dimensional subarray,
the central group of LEDs including central blue LEDs that are configured to emit central blue light and central yellow LEDs that are configured to emit central yellow light such that, when observed at a reference plane separated from the LED array, the central blue light and the central yellow light combine to appear as central white light having a central correlated color temperature, and
the border group of LEDs including border blue LEDs that are configured to emit border blue light and border yellow LEDs that are configured to emit border yellow light such that, when observed at the reference plane, the border blue light and the border yellow light combine to appear as border white light having a border correlated color temperature that is different from the central correlated color temperature.
