Abstract
Light emitting devices (LEDs) and methods of manufacturing LEDs are described. A method includes providing a layer of a wavelength converting material on a temporary tape. The wavelength converting material includes at least a binder or matrix material, particles of a non-luminescent material, and phosphor particles and has a concentration of 60%-90% by volume particles of the non-luminescent material and phosphor particles. The layer of the wavelength converting material is separated on the temporary tape to form multiple wavelength converting structures, which are provided on an array type frame. Heat and pressure are applied to the wavelength converting structures on the array type frame.
