Abstract
A multi-region lighting system for flat illumination with color balancing includes one or more light sources and an optic. The optic includes a first ridge structure. The first ridge structure is disposed in a first region at a center of the optic. The first region is for diverging light in an outward direction from the center. A second ridge structure is disposed in a second region at an outer portion of the optic for directing light downward using total internal reflection, where a direction from the one or more light sources toward the optic defines a downward direction.
