Abstract
A lighting device includes a plurality of light-emitting diodes including a first light-emitting diode with a non-rectangular shape in a top view, a submount to which each of the plurality of light-emitting diodes is coupled, and a plurality of conductive elements formed between the submount and the plurality of light-emitting diodes to electrically connecting at least a portion of the plurality of light-emitting diodes with each other in series.
Claims20
A light-emitting device, comprising:
- a substrate;
- a first mesa structure having a first side facing the substrate, a second side opposite to the first side, a plurality of electrodes arranged on the second side;
- and
- a second mesa structure adjacent to the first mesa structure on the substrate;
- wherein the first mesa structure and the second mesa structure have same shapes with different orientations, or different shapes, in a top view, and
- wherein the first mesa structure and the second mesa structure collectively have a pattern different from the shapes of the first mesa structure and the second mesa structure in the top view.
