Abstract
A method for forming a layer of phosphor material on an LED encapsulant structure includes forming a layer of a phosphor material on a first surface, disposing the first surface to cause the phosphor material to be in contact with a surface of the LED encapsulant structure, applying a pressure between the first surface and the surface of the LED encapsulant structure, and causing the layer of the phosphor material to be attached to the LED encapsulant structure.
