Abstract
An embodiment discloses a light-emitting apparatus including a light source for emitting a first light; a wavelength-converting layer, having a first arcuate shape, spaced apart from the light source, the wavelength-converting layer configured to absorb at least a portion of the first light and emit a second light; a transparent member disposed between the light source and the wavelength-converting layer; and a monolithic reflective layer having a second arcuate shape and configured to be reflective of at least the second light; wherein the wavelength-converting layer is positioned between the monolithic reflective layer and the light source, and the monolithic reflective layer is separated from the wavelength-converting layer by a space; and wherein the second light is configured to pass through the space before being reflected by the monolithic reflective layer.
