Abstract

The present invention comprises a process of mixing a luminous substance in powder form to a transferable grade molding compound in a pelletized or powder form, such as a clear epoxy, to derive a homogeneous mixture that can be pressed and sintered into solid pellets. The solid pellets are further processed so as to permit their deposition on and around a light emitting semiconductor driver so as to obtain a white light emitting semiconductor device. This white light emitting device can be used in a variety of lighting applications.

Claims

exact text as granted — not AI-modified
1 . A method of fabricating a light emitting device, comprising: 
 admixing a luminous substance to a transferable grade molding compound to derive a homogeneous mixture;    pressing and sintering the homogeneous mixture into solid pellets;    processing the solid pellets such that the solid pellets are adapted to be applied on a semiconductor surface; and    depositing the processed solid pellets on the semiconductor surface.    
   
   
       2 . The method of fabricating a light emitting device of  claim 1  wherein the molding compound is in a pelletized form prior to pressing and sintering the homogeneous mixture into solid pellets.  
   
   
       3 . The method of fabricating a light emitting device of  claim 1  wherein the pelletized molding compound further comprises a clear epoxy.  
   
   
       4 . The method of fabricating a light emitting device of  claim 1  wherein the molding compound is in a powdered form prior to pressing and sintering the homogeneous mixture into solid pellets.  
   
   
       5 . The method of fabricating a light emitting device of  claim 4  wherein the powdered molding compound further comprises a clear epoxy.  
   
   
       6 . The method of fabricating a light emitting device of  claim 1  wherein the luminous substance is in powdered form prior to pressing and sintering the homogeneous mixture into solid pellets.  
   
   
       7 . The method of fabricating a light emitting device of  claim 1  wherein the light emitting device is adapted to emit a white light.
