Abstract
The present disclosure involves lighting apparatus. The lighting apparatus includes a first doped semiconductor layer. A light-emitting layer is disposed over the first doped semiconductor layer. A second doped semiconductor layer is disposed over the light-emitting layer. The second doped semiconductor layer has a different type of conductivity than the first doped semiconductor layer. A photo-conversion layer is disposed over the second doped semiconductor layer and over side surfaces of the first and second doped semiconductor layers and the light-emitting layer. The photo-conversion layer has an angular profile.
