Abstract

Light-control panels including layered optical components are described in this application. An example of a light-control panel includes first and second glazing layers, first and second transitional layers extending between the first and second glazing layers that guide light emitted from a light source, and a third glazing layer extending between the first and second transitional layers through which light emitted from the light source is guided. The light-control panel also includes a light extraction layer extending between the third glazing layer and one of the first and second transitional layers that distributes light emitted from the light source. The first and second transitional layers have refractive indices that gradually decrease from a first value at surfaces proximate to the first and second glazing layers to a second value at surfaces proximate to the third glazing layer in the stack-up of the light-control panel.
