Abstract
A method for forming wavelength-conversion LED encapsulant structure includes forming an LED encapsulant structure body, forming a layer of a wavelength-conversion material on a first surface, disposing the first surface to cause the wavelength-conversion material to be in contact with a surface region of the LED encapsulant structure body, applying a pressure between the first surface and the surface region of the LED encapsulant structure body, and causing at least a portion of the wavelength-conversion material to be at least partially embedded in the surface region of the LED encapsulant structure body.
