Patent ID: 8421110

Claim:
A light emitting device comprising: a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer and an active layer between the first and second conductive semiconductor layers; a fluorescent layer on the light emitting structure; a light extracting structure on the fluorescent layer; a second electrode layer under the light emitting structure; and a Current Blocking Layer (CBL) between the light emitting structure and the second electrode layer, wherein the light extracting structure extracts light which is generated in the light emitting structure and incident into an interfacial surface between the fluorescent layer and the light extracting structure to an outside of the light emitting structure, wherein at least one upper portion of the fluorescent layer is exposed through the light extracting structure, and wherein the second electrode layer includes at least one of an ohmic layer, a reflection layer, a junction layer, and a support substrate.
