1. An LED based solid-state lamp comprising:

  • a submount having electrically insulative properties;

    conductive elements deposited on a surface of the submount; and

    a plurality of high voltage LED emitters on a semiconductor chip, the emitters existing in an array on a surface on a substrate which is on an opposite side of the emitters from the surface of the submount;

    the LED emitters being coupled with the surface on the submount and electrically connected with one another through the conductive elements, wherein the conductive elements are arranged in a configuration that includes a plurality of redundant conductive pathways between the emitters at the emitter level, the redundant pathways providing a ladderlike configuration of interconnections between emitters.
