LIGHT-EMITTING DEVICES AND LENS THEREFOR

摘要

A light-emitting assembly (100) for conditioning the light output of at least one light-emitting source (142) for light guide coupling, comprising a lens (120) and at least one light-emitting source (142), the light-emitting source having an optical output axis and the lens comprising a beam diverging portion (162) for diverging or spreading light about the optical output axis, wherein the beam diverging portion (162) of the lens is along the optical output axis and forward of the light-emitting source, and at least one beam converging portion (164, 166) for converging or compressing light away from the optical output axis is adjacent to the beam diverging portion (162).
