1. A light emitter device having improved chemical and physical resistance, the light emitter device comprising:
- a light emission area and one or more light emitting chips associated with the light emission area; and
a filling material at least partially disposed over the one or more light emitting chips, wherein the filling material comprises;
a first discrete layer of phosphor containing material that comprises a silicone or epoxy material; and
a second discrete clear barrier layer; and
a third discrete layer of clear encapsulant;
wherein the clear barrier layer comprises a layer of glass, wherein the first discrete layer of phosphor containing material is thicker than the second discrete clear barrier layer, and wherein the second discrete clear barrier layer is disposed between the first discrete layer of phosphor containing material and the third discrete layer of clear encapsulant.
