ABSTRACT:
A monolithic LED chip is disclosed comprising a plurality of junctions or sub-LEDs (“sub-LEDs”) mounted on a submount. The sub-LEDs are serially interconnected such that the voltage necessary to drive the sub-LEDs is dependent on the number of serially interconnected sub-LEDs and the junction voltage of the sub-LEDs. Methods for fabricating a monolithic LED chip are also disclosed with one method comprising providing a single junction LED on a submount and separating the single junction LED into a plurality of sub-LEDs. The sub-LEDs are then serially interconnected such that the voltage necessary to drive the sub-LEDs is dependent on the number of the serially interconnected sub-LEDs and the junction voltage of the sub-LEDs.
