Abstract:
1. A method for fabricating a light emitting device comprising: attaching a light source that generates light of a first wavelength to a substrate; attaching a reflecting cup to said substrate, said reflecting cup comprising reflective sidewalls, said die being located in said cup such that a portion of said light generated by said light source is reflected from said cup; applying a light converting layer comprising a volatile carrier material and particles of a phosphor that convert light of said first wavelength to light of a second wavelength over said die; and causing said volatile carrier material to evaporate thereby leaving a conformal layer of phosphor particles covering said light source and in direct contact therewith, said phosphor particles converting at least a portion of said light of said first wavelength to light of a second wavelength, said layer having a substantially uniform thickness of less than 100 μm over said light source, said layer of phosphor particles covering a portion of said reflective sidewalls.
