Claim Text:
1. A method for manufacture of an electronic device comprising: providing a solid, transparent, one-piece optic having a plurality of optical elements on a first side and a plurality of depressions defined by a second side opposite the first side, wherein at least one optical element is aligned with at least one depression; providing at least one phosphor chip, each phosphor chip (A) comprising (i) a light-conversion material present as a plurality of phosphorescent and/or fluorescent particles and (ii) a binder, comprising at least one of silicone or epoxy, wherein the phosphorescent and/or fluorescent particles are disposed within the binder, and (B) being a preformed, discrete solid piece; after providing the at least one phosphor chip and providing the optic, inserting each phosphor chip within a different depression in the optic; providing a substrate having a plurality of conductive traces on a surface thereof, each pair of conductive traces being separated on the substrate by a gap therebetween; providing a plurality of light-emitting elements (LEEs) each having (i) top and bottom opposed surfaces and (ii) first and second spaced-apart contacts disposed on the bottom surface, the optic being substantially transparent to at least one of a wavelength of light emitted by the LEEs or the at least one phosphor chip; for each LEE, (i) disposing the LEE over the substrate such that the bottom surface of the LEE extends across a gap disposed between a pair of conductive traces on the substrate and overlaps a portion of each of the conductive traces separated by the gap, (ii) electrically coupling the first contact of the LEE to one of the pair of conductive traces, and (iii) electrically coupling the second contact of the LEE to the other one of the pair of conductive traces; and after inserting each phosphor chip within a different depression in the optic and after electrically coupling the first and second contacts of each LEE to conductive traces, mating the substrate to the optic, whereby at least one phosphor chip is positioned to receive light from at least one LEE and each optical element is positioned to receive light from at least one LEE.
