Light emitting diodes are provided with electrode and pad structures that facilitate current spreading and heat sinking. A light emitting diode may be formed as a die with a stacked structure having a first region and a mesa projecting from a surface of the first region. A first electrode may substantially cover the mesa and have a plurality of pads disposed thereon maximizing a contact area in relation to the first electrode. A second electrode may be disposed as a trace on the surface of the first region, the trace having a spiral, segmented/interdigitated, loop or pattern. Optionally, the trace includes corner spikes projecting outwardly toward edges of the first electrode.
