A recently granted patent (Publication Number: US11774063B2) describes a color mixing lens assembly and a method for color mixing using this assembly. The assembly includes at least one light source that produces two different electromagnetic radiations. The assembly also includes an optic with a light source receiving structure that receives the electromagnetic radiations from the light source. Within the optic, there is a center mixing structure arranged concentrically, which receives a portion of the electromagnetic radiations from the light source receiving structure. This center mixing structure has a plated surface and a center kick structure, which is a layer of optical structures. The center kick structure reflects the received portion of the electromagnetic radiations towards the plated surface. The center mixing structure then reflects this portion of the radiations from the plated surface through an exit surface of the optic. Additionally, the optic reflects another portion of the radiations received from the light source receiving structure through the exit surface.

The patent also mentions various features and variations of the color mixing lens assembly. The optical structures within the center kick structure can be conical, pyramidal, or prismatic. The layer of optical structures can be a holographic film. The optical structures can be arranged radially about the layer. The exit surface of the optic can be a textured microlens. The first portion of the electromagnetic radiations exits the light source receiving structure through a flat surface. The center mixing structure can be frustoconical, and the plated surface can be a specular coating.

The patent also describes a method for color mixing using this color mixing lens assembly. The method involves generating the electromagnetic radiations using at least one radiation source, receiving these radiations at the light source receiving structure of the optic, and receiving a portion of the radiations by the center mixing structure. The center kick structure then reflects this portion of the radiations towards the plated surface, which in turn reflects the radiations through the exit surface of the optic. The optic also reflects another portion of the radiations through the exit surface.

Overall, this patent presents a color mixing lens assembly and a method that utilize various optical structures and surfaces to achieve color mixing of electromagnetic radiations. The assembly and method offer potential applications in fields such as lighting, displays, and imaging.
