Title:
PHOSPHOR-CONVERTED LED
Document Type and Number:
WIPO Patent Application WO/2010/027672
Kind Code:
A3
Abstract:
A light source [30] and method for fabricating the same are disclosed. The light source includes a die [31], a light conversion component [33], and a scattering ring [34]. The die emits [31] 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 [32]. The light conversion component [33] 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 [31]. The light conversion component [33] has lateral dimensions such that a space exists around the die, the space being bounded by the substrate [32] and the light conversion component [33]. The scattering ring [34] is positioned in the space such that a portion of the light emitted from the side surfaces of the die[31] is scattered into the light conversion component [33].
