1. A phosphor-containing thermosetting silicone resin sheet, comprising:
a substrate film; and a plurality of phosphor-containing thermosetting silicone resin pieces arranged in a single, discontinuous layer on the substrate film; wherein: each phosphor-containing thermosetting silicone resin piece:
is composed of a single layer of an uncured phosphor-containing thermosetting silicone resin composition that has a plastic solid or semi-solid state at room temperature, andhas a surface shape that conforms to a shape of a surface of an LED device to which the phosphor-containing thermosetting silicone resin piece is intended to be laminated; and the phosphor-containing thermosetting silicone resin composition comprises: (A) a resin structure organopolysiloxane having an R1SiO1.5 unit, an R22SiO unit, and an R3aR4bSiO(4-a-b)/2 unit, wherein:
R1, R2, and R3 each independently represents a methyl group, an ethyl group, a propyl group, a cyclohexyl group, or a phenyl group,R4 independently represents a vinyl group or an allyl group,a is 0, 1, or 2,b is 1 or 2,a+b=2 or 3, andat least part of the R22SiO unit is in a continuous repeating sequence with 5 to 300 repeating units; (B) a resin structure organohydrogen polysiloxane having an R1SiO1.5 unit, an R22SiO unit, and an R3cHdSiO(4-c-d)/2 unit, wherein:
R1, R2, and R3 are as defined in (A),c is 0, 1, or 2,d is 1 or 2,c+d=2 or 3,at least part of the R22SiO unit is in a continuous repeating sequence with 5 to 300 repeating units, anda molar ratio of a hydrogen atom bonded to a silicon atom in the (B) component relative to a total of a vinyl group and an allyl group in the (A) component is 0.1 to 4.0: (C) a platinum group metal-based catalyst, wherein the amount is a curing effective amount: (D) a phosphor; and (E) an organic solvent. |
