High reliability high voltage vertical LED arrays

An array of high-voltage vertical light-emitting diodes comprising:

• a plurality of vertical light-emitting diodes, each vertical light emitting diode including a first electrode positioned on a light-emitting face of the vertical light-emitting diode and a second electrode positioned on a second surface of the vertical light-emitting diode;
• a conductive matrix surrounding each of the high-voltage vertical light emitting diodes and electrically communicating with each of the first electrodes and with each of the second electrodes of each of the high-voltage vertical light emitting diodes;
• an isolating material positioned in the conductive matrix between adjacent second electrodes of each of the high-voltage vertical light emitting diodes to isolate the adjacent second electrodes from one another such that a first electrical current path is defined between the second and first electrodes through each of the high voltage vertical light emitting diodes;
• and a resistance-changing material configured to permanently lower its resistance when subjected to a predetermined electrical voltage and/or current positioned between adjacent high-voltage vertical light emitting diodes for providing an alternate electrical pathway through the conductive matrix following a failure of an individual high-voltage vertical light emitting diode resulting in the application of the predetermined electrical voltage and/or current.
