Abstract

A light emitting apparatus has a light source for emitting a first light in a forward direction. A wavelength-converting layer is spaced apart from the light source and disposed in a path of the first light. The wavelength-converting layer is configured to absorb at least a portion of the first light and emit a second light. A reflective layer is configured to be reflective of at least the second light, and the wavelength-converting layer is disposed between the reflective layer and the light source.
