Abstract
A lighting apparatus includes at least one LED and a chromaticity tuning cavity adapted to capture light from the LED. The chromaticity tuning cavity is defined by a light translucent window and a plurality of backscattering light recycling surfaces. The light translucent window is adapted to backscatter at least a portion of the LED light. A preselected chromaticity tuning member is positioned within the chromaticity tuning cavity. It is selected from a group of chromaticity tuning members adapted to tune the chromaticity of various lighting apparatuses within one quadrangle on a chromaticity diagram. At least a portion of the LED light, having been backscattered and tuned by the preselected tuning member, passes through the light translucent window as warm white extraction light.
