Light-emitting assembly and method for manufacturing the same

Abstract

A light-emitting assembly and a method for manufacturing the same are provided. The light-emitting assembly includes a circuit board with a light-emitting element and a plurality of optical microstructures disposed thereon. The optical microstructures adjacent to the light-emitting element absorb or guide a portion of light emitted from the light-emitting element.

What is claimed is: 
     
         1 . A light-emitting assembly, comprising:
 a circuit board;   a light-emitting element disposed on the circuit board; and   a plurality of optical microstructures disposed on the circuit board and adjacent to the light-emitting element, wherein the optical microstructures absorb or guide a portion of light emitted from the light-emitting element and the optical microstructures are made from an ink comprising light-absorbing or light-reflecting material.   
     
     
         2 . The light-emitting assembly as claimed in  claim 1 , wherein the optical microstructures are formed in a region where the light emitted from the light-emitting element is predicted to have a higher density and form a bright band. 
     
     
         3 . The light-emitting assembly as claimed in  claim 2 , wherein the optical microstructures have a cone or hemisphere shape. 
     
     
         4 . The light-emitting assembly as claimed in  claim 1 , wherein the light-absorbing material comprises organic or mineral dye. 
     
     
         5 . The light-emitting assembly as claimed in  claim 1 , wherein the light-reflecting material comprises high reflective oxide and/or high reflective metal. 
     
     
         6 . The light-emitting assembly as claimed in  claim 1 , wherein the light-reflecting material comprises titanium dioxide, aluminum, and/or silver. 
     
     
         7 . The light-emitting assembly as claimed in  claim 1 , wherein the light-emitting element comprises a light-emitting diode (LED). 
     
     
         8 . The light-emitting assembly as claimed in  claim 7 , further comprising a lens covering the light-emitting element. 
     
     
         9 . The light-emitting assembly as claimed in  claim 1 , further comprising a lens covering the light-emitting element.
