Open reel

Abstract

An open reel ( 1 ) according to the present invention includes a reel ( 30 ) and a phosphor-containing resin ( 20 ) in the form of a cord wound around the reel ( 30 ).

1 . An open reel comprising:
 a reel; and   a phosphor-containing resin in a form of a cord wound around the reel, wherein   the phosphor-containing resin being such that at least a phosphor is dispersed in a thermoplastic resin, and   the thermoplastic resin being a silicone resin which is thermoplastic at a temperature that is less than a predetermined cross-linking temperature, and which is irreversibly cured at a temperature that is greater than or equal to the cross-linking temperature.   
     
     
         2 . (canceled) 
     
     
         3 . The open reel according to  claim 1 , wherein the cross-linking temperature is in a range of 120° C. to 170° C. 
     
     
         4 . The open reel according to  claim 1 , wherein the thermoplastic resin contains a solvent containing benzene, toluene, and xylene. 
     
     
         5 . An open reel comprising:
 a reel; and   a phosphor-containing resin in a form of a cord wound around the reel, wherein   the phosphor-containing resin having portions having different phosphor contents along an axial direction of the phosphor-containing resin.   
     
     
         6 . The open reel according to  claim 1 , wherein two or more of the phosphor-containing resins having the same phosphor content or different phosphor contents are wound around the reel, the number of reels being one.
