Lead frame, and light emitting diode module having the same

Abstract

A light emitting diode (LED) module includes a lead frame having a number (N) of conducting arms spaced apart from each other, where N≧3, and at least one LED die mounted on one of any two neighbor conducting arms. Any two neighbor conducting arms are electrically coupled each other.

1 . A light emitting diode (LED) module comprising:
 a lead frame having a number (N) of conducting arms spaced apart from each other, where N≧3; and   at least one LED die mounted on one of any two neighbor said conducting arms;   wherein any two neighbor said conducting arms are electrically coupled to each other.   
     
     
         2 . The LED module as claimed in  claim 1 , wherein each of said LED dice has two conductive contacts, and any two neighbor said conducting arms are electrically coupled to each other by said two conductive contacts of said LED die. 
     
     
         3 . The LED module as claimed in  claim 1 , further comprising an insulating casing for partly covering said lead frame, wherein said insulating casing is formed with a plurality of openings corresponding respectively to said LED dice such that said LED dice are exposed through said openings. 
     
     
         4 . The LED module as claimed in  claim 3 , further comprising light-transmissive resin filled in said openings in said insulating casing. 
     
     
         5 . The LED module as claimed in  claim 4 , wherein said light-transmissive resin comprises fluorescent material. 
     
     
         6 . The LED module as claimed in  claim 1 , wherein two of said conducting arms have a projection extending toward each other so that the other (N−2) ones of said conducting arms are disposed between said two projections. 
     
     
         7 . The LED module as claimed in  claim 6 , further comprising an insulating casing for partly covering said lead frame, wherein said insulating casing is formed with a plurality of openings corresponding respectively to said LED dice such that said LED dice are exposed through said openings. 
     
     
         8 . The LED module as claimed in  claim 7 , further comprising light-transmissive resin filled in said openings in said insulating casing. 
     
     
         9 . A structure having a lead frame adapted for mounting light emitting diode (LED) dice thereon and an insulating casing partly covering said lead frame, said structure comprising:
 a number (N) of conducting arms spaced apart from each other and said insulating casing is formed therebetween for providing electric insulation, where N≧3; and   wherein a plurality of openings are formed in said insulating casing for containing said LED dice.   
     
     
         10 . The structure as claimed in  claim 9 , wherein two of said conducting arms have a projection extending toward each other so that the other (N−2) ones of said conducting arms are disposed between said two projections. 
     
     
         11 . The structure as claimed in  claim 9 , wherein each of said openings is defined by an inner surrounding wall surrounding the corresponding one of the LED dice. 
     
     
         12 . The structure as claimed in  claim 11 , wherein said inner surrounding wall is formed with a light reflecting layer for light reflection. 
     
     
         13 . The structure as claimed in  claim 11 , wherein said inner surrounding wall is formed with fluorescent layer. 
     
     
         14 . The structure as claimed in  claim 9 , wherein each of said openings is gradually converged toward the corresponding one of said LED dice. 
     
     
         15 . The structure as claimed in  claim 9 , wherein said insulating casing is further formed with a plurality of auxiliary structures, each of said auxiliary structures being disposed between two adjacent ones of said openings for ensuring flexibility of said structure. 
     
     
         16 . The structure as claimed in  claim 15 , wherein said insulating casing has two kinds of thicknesses, and is thinner at a location corresponding to that of said auxiliary structures. 
     
     
         17 . The structure as claimed in  claim 15 , wherein said openings and said auxiliary structures lie on a same horizontal plane. 
     
     
         18 . The structure as claimed in  claim 15 , wherein said auxiliary structures are formed with openings or recesses. 
     
     
         19 . The structure as claimed in  claim 18 , wherein any two adjacent ones of said auxiliary structures are toward different directions. 
     
     
         20 . The structure as claimed in  claim 18 , wherein said conducting arms are partly exposed from said auxiliary structures.
