Abstract:
A lighting apparatus includes a substrate, a plurality of light-emitting dies, a continuous encapsulation structure, and a gel. The plurality of light-emitting dies are disposed on the substrate and spaced apart from one another. The light-emitting dies each are covered with a respective individual phosphor coating conformally. The continuous encapsulation structure has a curved surface disposed over the substrate and encapsulates the light-emitting dies within. The gel is disposed between the encapsulation structure and the phosphor coating for each of the light-emitting dies. The gel contains diffuser particles. The lighting apparatus has a substantially white appearance in an off state when the plurality of light-emitting dies is turned off.
