主权项 1. A solid state lighting component comprising: a substrate having a top surface, the top surface of the substrate comprising a first region comprising a die pad;a second region comprising a light absorbing feature, the second region being spaced apart from and within the first region of the top surface of the substrate; and a three dimensional near field reflective structure comprising a first shape positioned within the first region, the first shape at least partially surrounding the die pad, and a second shape positioned within the second region at least partially covering the light absorbing feature, the second shape positioned within the second region being spaced apart from the first shape; an LED element, wherein the first and the second shapes comprise polydimethylsiloxane, polyphenylsiloxane, or blends thereof, and an amount of titanium dioxide material sufficient for scattering and/or reflecting emitted light emitted from the LED element, reduce absorption of the emitted light, and combinations thereof, wherein the LED element is part of an array of LED elements, at least one of the first and the second shapes at least partially surrounding one or more individual LED elements of the array of LED elements and/or the array of LED elements, the polydimethylsiloxane, polyphenylsiloxane, or blends thereof being substantially transparent and substantially non-absorbing to light emitted by the LED element.
