Abstract
A color mixing lens assembly is provided. The color mixing assembly may include a center mixing structure arranged concentrically within the optic. The center mixing structure may be configured to receive a first portion of electromagnetic radiation from a light receiving structure. The center mixing structure may include a plated surface. The center mixing structure may include a center kick structure arranged concentrically within the center mixing structure. The center kick structure may be configured to reflect the first portion of the electromagnetic radiation towards the plated surface. The center mixing structure may be configured to reflect the first portion of the electromagnetic radiation from the plated surface through an exit surface of the optic. The optic may be configured to reflect a second portion of the electromagnetic radiation received from the light source structure through the exit surface of the optic.
