Patent ID: 7607792

Claim:
A light-emitting assembly for conditioning the light output of at least one light-emitting source for light guide coupling, comprising a lens and at least one light-emitting source, said light-emitting source having an optical output axis and said lens comprising a beam diverging portion for diverging or spreading light along a first optical plane about said optical output axis, said optical axis lying within said first optical plane, wherein said beam diverging portion of said lens is along said optical output axis and forward of said light-emitting source, and a beam converging portion for converging or compressing light along said first optical plane away from said optical axis is adjacent said beam diverging portion; wherein another beam converging portion for converging or compressing light away from said optical axis is adjacent said beam diverging portion such that said beam diverging portion of said lens is intermediate said beam converging portion and said another beam converging portion; said beam diverging portion, said beam converging portion and said another beam converging portion are intermediate a pair of beam collimating lens portions, and said pair of beam collimating lens portions being along a plane orthogonal to said first plane and being substantially parabolic such that the optical output from said light-emitting source along said orthogonal plane is collimated towards said light guide in a direction towards said optical output axis.
