Manufacturing method for light-emitting device

Abstract

A light-emitting device production method includes a positioning step of positioning, in a light-emitting element, a sealing member at least containing a silicone resin semi-cured at a room temperature (T 0 ) by primary cross-linking and a fluorescent material, the silicone resin decreasing in viscosity reversibly in a temperature region between the room temperature (T 0 ) and a temperature lower than a secondary cross-linking temperature (T 1 ), and being totally cured non-reversibly in a temperature region equal to or higher than the secondary cross-linking temperature (T 1 ).

1 .- 25 . (canceled) 
     
     
         26 . A sealing member comprising:
 at least a thermoplastic resin and a fluorescent material,   the thermoplastic resin being thermoplastic at a temperature lower than a predetermined cross-linking temperature, and being cured non-reversibly at a temperature equal to or higher than the predetermined cross-linking temperature.   
     
     
         27 . The sealing member as set forth in  claim 26 , wherein the thermoplastic resin is subjected to primary cross-linking at the temperature lower than the predetermined cross-linking temperature, and the thermoplastic resin is subjected to secondary cross-linking at the temperature equal to or higher than the predetermined cross-linking temperature. 
     
     
         28 . The sealing member as set forth in  claim 26 , wherein the predetermined cross-linking temperature is not lower than 120° C. and not higher than 170° C. 
     
     
         29 . The sealing member as set forth in  claim 26 , wherein the sealing member is a sealing sheet obtained by molding, into a sheet, the thermoplastic resin in which the fluorescent material is dispersed. 
     
     
         30 . The sealing member as set forth in  claim 29 , wherein the sealing sheet is provided with a through hole. 
     
     
         31 . The sealing member as set forth in  claim 29 , wherein the sealing sheet has a surface provided with a plurality of recesses. 
     
     
         32 . The sealing member as set forth in  claim 29 , wherein the sealing sheet has a surface provided with a plurality of protrusions. 
     
     
         33 . The sealing member as set forth in  claim 26 , wherein the sealing member is sealing powder containing at least powder of the thermoplastic resin in which the fluorescent material is dispersed. 
     
     
         34 . The sealing member as set forth in  claim 26 , wherein the sealing member is sealing powder in which at least (i) powder of the thermoplastic resin and (ii) powder of the fluorescent material are mixed. 
     
     
         35 . The sealing member as set forth in  claim 34 , wherein in the sealing powder, (i) the powder of the thermoplastic resin and (ii) the powder of the fluorescent material the sealing powder differ in particle size. 
     
     
         36 . The sealing member as set forth in  claim 33 , wherein the sealing powder is compressed into a predetermined shape. 
     
     
         37 . The sealing member as set forth in  claim 36 , wherein the predetermined shape is a tablet. 
     
     
         38 . The sealing member as set forth in  claim 36 , wherein the predetermined shape is a sheet. 
     
     
         39 . The sealing member as set forth in  claim 33 , wherein powder of the thermoplastic resin subjected to secondary cross-linking is further mixed in the sealing powder. 
     
     
         40 . The sealing member as set forth in  claim 26 , wherein the thermoplastic resin contains a solvent containing benzene, toluene, and xylene.
