A light emitter, comprising light emitting devices mechanically interconnected by a common substrate and an interconnection submount. The light emitting devices are electrically interconnected by the submount to provide an array of serially connected subsets of light emitting devices, each subset comprising at least three light emitting devices electrically connected in parallel. Also, a light emitter comprising first light emitting devices mechanically interconnected by a first common substrate, and second light emitting devices mechanically interconnected by a second common substrate, the first light emitting devices being mechanically and electrically connected to the second light emitting devices. Also, a light emitter comprising mechanically interconnected light emitting devices and means for mechanically and electrically interconnecting the plurality of light emitting devices to provide an array of serially connected subsets of light emitting devices, each subset comprising at least three light emitting devices electrically connected in parallel. Also, methods of fabricating light emitters.
