An LED chip comprising a plurality of sub-LEDs on a submount. Electrically conductive and electrically insulating features are included that serially interconnect the sub-LEDs such that an electrical signal applied to the serially interconnected sub-LEDs along the electrically conductive features spreads to the serially interconnected sub-LEDs. A via is included that is arranged to electrically couple one of the sub-LEDs to the submount. The sub-LEDs can be interconnected by more than one of the conductive features, with each one of the conductive features capable of spreading an electrical signal between two of the sub-LEDs.
