Phosphor-converted LED
Abstract:
A light source and method for fabricating the same are disclosed. The light source includes a die, a light conversion component, and a scattering ring. The die emits light of a first wavelength through a top surface of the die and one or more side surfaces of the die, and is bonded to a mounting substrate. The light conversion component converts light of the first wavelength to light of a second wavelength, the light conversion component having a bottom surface bonded to the top surface of the die. The light conversion component has lateral dimensions such that a space exists around the die, the space being bounded by the substrate and the light conversion component. The scattering ring is positioned in the space such that a portion of the light emitted from the side surfaces of the die is scattered into the light conversion component.
