Abstract:
1. An electronic device comprising: a packaging substrate having a packaging face, the packaging substrate including first, second, and third electrically conductive structures on the packaging face; and first and second pluralities of light emitting diodes electrically and mechanically coupled to the packaging face of the packaging substrate, wherein the light emitting diodes of the first plurality of light emitting diodes are electrically coupled in parallel between the first electrically conductive structure and the second electrically conductive structure on the packaging face, wherein the light emitting diodes of the second plurality of light emitting diodes are electrically coupled in parallel between the second electrically conductive structure and the third electrically conductive structure, wherein the packaging substrate is free of wirebonds electrically coupled between the packaging substrate and any of light emitting diodes of the first and second pluralities of light emitting diodes, and wherein each of the light emitting diodes has a forward voltage drop of at least 2.5 volts so that a voltage drop between the first and third electrically conductive structures is at least 5.0 volts, wherein the first electrically conductive structure and the second electrically conductive structure define an electrically insulating gap therebetween wherein a portion of the electrically insulating gap that is between first and second light emitting diodes of the first plurality of light emitting diodes has a width that is less than a width of the first light emitting diode, and wherein the electrically insulating gap comprises a first linear portion and a second linear portion which are separated by a non-linear portion, wherein the first and second linear portions of the gap and the non-linear portion of the gap define an extension of the first electrically conductive structure, wherein the first and second linear portions of the gap define respective first and second sides of the extension of the first electrically conductive structure, wherein a first portion of the second electrically conductive structure is adjacent to the first side of the extension, wherein a second portion of the second electrically conductive structure is adjacent to the second side of the extension, wherein the first light emitting diode spans the first linear portion of the gap from the first side of the extension to the first portion of the second electrically conductive structure, and wherein the second light emitting diode spans the second linear portion of the gap from the second side of the extension to the second portion of the second electrically conductive structure.
