ABSTRACT:
A bendable light emitting diode (LED) array in accordance with the present invention includes heat spreaders, dielectric material disposed above each heat spreader, and a bendable electrical interconnection layer disposed above these heat spreaders and electrically insulated from these heat spreaders by the dielectric material. At least one via passes through the dielectric material above each heat spreader, and at least one LED die is disposed above each via. The bendable electrical interconnection layer may be a lead frame comprising metal pathways that electrically interconnect some or all LED dice in series, in parallel, in anti-parallel, or in some combination of these configurations. Each via contains a thermally conductive material in thermal contact with the corresponding heat spreader below it and in thermal contact with the corresponding LED die above it. The LED dice may be thermally and electrically coupled to submounts disposed above corresponding heat spreaders in some embodiments.
