Patent ID: 8803166

Claim:
An arrangement of light emitting diodes, comprising: a substrate; and four adjoining light-emitting units forming a light-emitting array on said substrate, each unit comprising at least one micro-die, each micro-die comprising: a lower semiconductor layer of first conductivity on said substrate; an upper semiconductor layer of second conductivity opposite to the first conductivity on said lower semiconductor layer; a first connecting portion disposed on the lower semiconductor layer; and a second connecting portion disposed on the upper semiconductor layer, wherein the first connecting portion and the second connecting portion are respectively located near different sides of the micro-die, and wherein the four adjoining light-emitting units comprise a first group of the connecting portions comprising four connecting portions disposed substantially at a center of the light-emitting array, and a second group of the connecting portions comprising another four connecting portions disposed substantially at the periphery of the light-emitting array.
