Abstract:
1. An apparatus, comprising: a substrate with a upper surface; light emitting diode (LED) dies disposed on the upper surface of the substrate, wherein a surface emitter length is a maximum distance between farthest apart edges of the LED dies; a lens material disposed on the upper surface of the substrate over the LED dies, wherein the lens material is shaped as a portion of a sphere having a dome and a radius, and wherein a dome height extends from a top of the dome to the upper surface of the substrate; and phosphor particles disbursed throughout the lens material, wherein a bottom chord length is a maximum length that the lens material extends over the upper surface of the substrate, wherein the bottom chord length is less than twice the surface emitter length, and wherein the dome height is between 57% and 73% of the radius.
