Claim:
1. A light-emitting apparatus comprising: a single growth sapphire substrate on an entire main surface of which Group III nitride semiconductor layers are grown; a plurality of light-emitting devices comprising the Group III nitride semiconductor layers on the growth sapphire substrate, each of the light-emitting devices comprising a buffer layer, a first conductive type first semiconductor layer, a light-emitting layer, a second conductive type second semiconductor layer, a first electrode electrically connected to the first semiconductor layer, and a second electrode electrically connected to the second semiconductor layer, wherein the first electrode and the second electrode are formed on a same side of the light-emitting device, and a fluorescent material which covers a surfaces of the light-emitting devices; wherein each of the light-emitting devices are isolated from each other by a groove formed on the main surface of the growth sapphire substrate, wherein the light-emitting apparatus comprises: wherein a serial connection circuit of some of the good light-emitting devices is formed by the bonding wire for adjacent connection and the bonding wire for bypass connection.
