Patent ID: 7285801

Claim:
A light emitting device comprising: an electrically insulating substrate; a plurality of elongated light emitting diode mesas disposed generally parallel to one another on the substrate, the mesas being electrically isolated from one another, each light emitting diode mesa defined by a stack of layers including a first conductivity type layer disposed between the substrate and a second conductivity type layer and further including at least one of: an active region disposed between the first conductivity type layer and the second conductivity type layer, and a buffer layer disposed between the substrate and the first conductivity type layer; and electrically conductive connection material disposed on the substrate between neighboring elongated light emitting diode mesas, the conductive material electrically connecting the first conductivity type layer of one mesa with the second conductivity type layer of the neighboring mesa along the long dimension of the neighboring elongated mesas to series-interconnect the light emitting diode mesas.
