Abstract
A lighting system comprises a light source having an exit window and an electrically controllable light processing arrangement, in the form of a grid of cells lying in a plane parallel to the exit window. Each cell has a cell wall formed as electrically switchable element which is switchable between at least two processing modes. The cell wall surrounds an opening, such that light emitted in a normal direction from the light source exit window is not processed, and light passing at an angle to the normal direction greater than a threshold angle is processed by the cell wall for color and/or intensity control.
