1. An illumination source comprising:
a light integrating device for coupling to at least one optical structure at an output port, where the light integrating device includes at least one input port;
at least one light source for producing at least one optical illumination coupled to the at least one input port; and
a light adjusting tool for controlling the optical illumination emitted by the light integrating device, wherein the light adjusting tool controls uniformity of light emitted by the light integrating device by modifying at least one internal surface of the light integrating device, and wherein the light integrating device comprises a conical internal shape with an apex at the output port coupling to the at least one optical structure.
