ABSTRACT:
An optical device deploring a phosphor layer having a textured surface to improve output of visual light is disclosed. A light emitting device includes a solid state light emitter and a phosphor layer. The solid state light emitter, for example, is configured to convert electrical energy to optical light. The phosphor layer includes a first surface and a second surface, wherein the first surface, for example, is the top surface while the second surface is the bottom surface. The phosphor layer is disposed over the solid state light emitter for generating luminous light in response to the optical light. The first surface of the phosphor layer, in one embodiment, is configured to include a texture, which has similarly shaped uniform configurations, capable of reducing total internal reflection.
