Abstract

Phosphor layer arrangement for use with light emitting diodes. In an aspect, a light emitting diode apparatus is provided that includes a least one light emitting diode, an encapsulation covering the at least one light emitting diode, a lens having a phosphor layer formed upon a bottom surface, the lens positioned to cover at least part of the encapsulation, and an air gap between the phosphor layer and the encapsulation. In an aspect, a light emitting diode lamp is provided that includes a package, a least one light emitting diode, an encapsulation covering the at least one light emitting diode, a lens having a phosphor layer formed upon a bottom surface, wherein the lens is positioned to cover at least part of the encapsulation, and an air gap between the phosphor layer and the encapsulation.

Claims

exact text as granted — not AI-modified
1 . A light emitting diode lamp comprising:
 a package;   a least one light emitting diode;   an encapsulation covering the at least one light emitting diode;   a lens having a phosphor layer formed upon a bottom surface, wherein the lens is positioned to cover at least part of the encapsulation; and   an air gap between the phosphor layer and the encapsulation.   
   
   
       2 . The lamp of  claim 1 , wherein said phosphor layer comprises an inorganic dye. 
   
   
       3 . The lamp of  claim 1 , wherein said phosphor layer has a uniform thickness. 
   
   
       4 . The lamp of  claim 1 , wherein said phosphor layer has a varying thickness. 
   
   
       5 . The lamp of  claim 1 , wherein said phosphor layer has a thickness in the range of 5 to 500 microns. 
   
   
       6 . The lamp of  claim 1 , wherein said air gap has a thickness in the range of 5 to 1000 microns. 
   
   
       7 . The lamp of  claim 1 , further comprising a stepped reflector that forms a boundary for the encapsulation. 
   
   
       8 . The lamp of  claim 7 , wherein said stepped reflector comprises a wire bonding region. 
   
   
       9 . An illumination device comprising:
 a power source;   a light emitting diode lamp in electrical communication with the power source, the light emitting diode lamp comprising:   a package;   a least one light emitting diode;   an encapsulation covering the at least one light emitting diode;   a lens having a phosphor layer formed upon a bottom surface, wherein the lens is positioned to cover at least part of the encapsulation; and   an air gap between the phosphor layer and the encapsulation.   
   
   
       10 . The illumination device of  claim 9 , wherein said phosphor layer comprises an inorganic dye. 
   
   
       11 . The illumination device of  claim 9 , wherein said phosphor layer has a uniform thickness. 
   
   
       12 . The illumination device of  claim 9 , wherein said phosphor layer has a varying thickness. 
   
   
       13 . The illumination device of  claim 9 , wherein said phosphor layer has a thickness in the range of 5 to 500 microns. 
   
   
       14 . The illumination device of  claim 9 , wherein said air gap has a thickness in the range of 5 to 1000 microns. 
   
   
       15 . The illumination device of  claim 9 , further comprising a stepped reflector that forms a boundary for the encapsulation. 
   
   
       16 . The illumination device of  claim 15 , wherein said stepped reflector comprises a wire bonding region. 
   
   
       17 . A light emitting diode apparatus comprising:
 a least one light emitting diode;   an encapsulation covering the at least one light emitting diode; and   a lens having a phosphor layer formed between first and second lens portions, the lens positioned so that the second lens portion fits against the encapsulation.   
   
   
       18 . The apparatus of  claim 17 , wherein said phosphor layer comprises an inorganic dye. 
   
   
       19 . The apparatus of  claim 17 , wherein said phosphor layer has a uniform thickness. 
   
   
       20 . The apparatus of  claim 17 , wherein said phosphor layer has a varying thickness. 
   
   
       21 . The apparatus of  claim 17 , wherein said phosphor layer has a thickness in the range of 5 to 500 microns. 
   
   
       22 . The apparatus of  claim 17 , further comprising a stepped reflector that forms a boundary for the encapsulation. 
   
   
       23 . The apparatus of  claim 22 , wherein said stepped reflector comprises a wire bonding region.
