Abstract

An illumination system can include a dual junction light-emitting diode (LED) array including first and second junctions that extend in a plane. The first junction can emit first light from a plurality of first light-emitting areas that are separated by first boundaries. The second junction can be disposed on the first junction such that the first light passes through the second junction. The second junction can emit second light from a plurality of second light-emitting areas. The second light-emitting areas can be separated by second boundaries that correspond in a one-to-one correspondence to the first boundaries. The second boundaries can be offset in the plane from the corresponding first boundaries. The offset can help reduce or eliminate dark bands in the combined first and second light, which could be present if the second boundaries were not offset from the first boundaries.
