Patent ID: 8354665

Claim:
A semiconductor light-emitting device, comprising: a conductive substrate; a multilayer semiconductor structure situated above the conductive substrate comprising: a first doped semiconductor layer; a second doped semiconductor layer situated above the first doped semiconductor layer; and a multiple-quantum-well (MQW) active layer situated between the first and the second doped semiconductor layers; wherein the multilayer semiconductor structure is divided by grooves to form a plurality of independent light-emitting mesas, wherein the light-emitting mesas have a common MQW; wherein a first light-emitting mesa comprises a first color conversion layer configured to convert light emitted by the first light-emitting mesa to a first color; wherein a second light-emitting mesa comprises a second color conversion layer configured to convert light emitted by the second light-emitting mesa to a second color that is different from the first color; and wherein a first light-emission intensity of the first light-emitting mesa and a second light-emission intensity of the second light-emitting mesa are electrically controlled and are independent of each other, thereby allowing light emitted by the semiconductor light-emitting device to have an arbitrary color; a first electrode coupled to the conductive substrate; a plurality of electrodes coupled to the second doped semiconductor layer of the plurality of the light-emitting mesas, wherein the plurality of electrodes can be controlled independently.
