The present disclosure involves a lighting apparatus. The lighting apparatus includes a polygon die. The polygon die includes a plurality of light-emitting diodes (LEDs). Each LED includes a plurality of epi-layers, the epi-layers containing a p-type layer, an n-type layer, and a multiple quantum well (MQW) disposed between the p-type layer and the n-type layer. Each LED includes a p-type electrode and an n-type electrode electrically coupled to the p-type layer and the n-type layer, respectively. The polygon die also includes a submount to which each of the LEDs is coupled. The p-type and the n-type electrodes are located between the submount and the epi-layers. The submount contains a plurality of conductive elements configured to electrically couple at least a portion of the plurality of LEDs in series. |
