Two component glass body for tape casting phosphor in glass led converters

Abstract

The present invention is directed to a method for preparing a glass device comprising the steps of: —preparing a mixture comprising: —at least two glass components, —a solvent, —at least one binder system, —optionally at least one defoamer, —blending the mixture to form a blend mixture, —grinding the blend mixture to form a grinded mixture, —casting the grinded mixture to form a layer, and —drying the layer to form a dried layer of a glass device. The present invention is further directed to a glass device, a wavelength converter and a light emitting device comprising the glass device and/or the wavelength converter.

1 . A method for preparing a glass device, the method comprising:
 preparing a mixture comprising at least two glass components, a solvent and at least one binder system;   blending the mixture to form a blended mixture;   grinding the blended mixture to form a grinded mixture;   casting the grinded mixture to form a layer; and   drying the layer to form a dried layer of the glass device.   
     
     
         2 . The method according to  claim 1 , further comprising assembling at least two dried layers together. 
     
     
         3 . The method according to  claim 1 , further comprising punching the dried layer into at least one plate. 
     
     
         4 . The method according to  claim 3 , further comprising sintering the at least one plate. 
     
     
         5 . The method according to  claim 1 , wherein the mixture further comprises at least one phosphor. 
     
     
         6 . (canceled) 
     
     
         7 . The method according to  claim 1 , wherein the mixture further comprises at least one phosphor comprising a rare earth activated yttrium aluminum oxide garnet structure. 
     
     
         8 . The method according to  claim 1 , wherein the solvent is water. 
     
     
         9 . The method according to  claim 1 , wherein the binder system comprises a binding agent and a plasticizer. 
     
     
         10 . The method according to  claim 1 , wherein the at least two glass components have a different softening point. 
     
     
         11 . The method according to  claim 1 , wherein at least one of the two glass components has a softening point of between about 900° C. and about 1000° C. inclusive and/or at least one of the two glass components has a softening point of between about 700° C. and about 800° C. inclusive. 
     
     
         12 . The method according to  claim 1 , wherein the mixture further comprises at least one defoamer.
