1. A light emitter, comprising:

  • a plurality of light emitting devices mechanically interconnected by a common substrate on which the light emitting devices are formed; and

    a plurality of fuse links,wherein;

    the light emitting devices are electrically interconnected on the common substrate to provide an array of at least two serially connected subsets of parallel connected light emitting devices, each subset comprising at least three light emitting devices, the light emitter comprising at least first and second subsets of light emitting devices, the first subset comprising at least first, second and third light emitting devices, the second subset comprising at least fourth, fifth and sixth light emitting devices, anda first fuse link electrically connected in series with the first light emitting device, the second fuse link electrically connected in series with the second light emitting device, the third fuse link electrically connected in series with the third light emitting device, the fourth fuse link electrically connected in series with the fourth light emitting device, the fifth fuse link electrically connected in series with the fifth light emitting device, the sixth fuse link electrically connected in series with the sixth light emitting device.
