ABSTRACT:
The lighting system for an aircraft cabin includes multiple illuminating units for distribution about a cabin. Each illuminating unit includes at least one variable light source providing light of a known characteristic and that is energizeable independently of other illuminating units. A controller controls energization of the illuminating units by way of dimming and switching units associated respectively with the illuminating units. The controller is operable to create different predetermined combinations of energizations of the illuminating units so that a desired lighting scene is created within the cabin by the energized illuminating units. The controller is arranged to effect a gradual transition to the energizations of the illuminating units when changing from one predetermined combination to another. As a result, there is a corresponding gradual change between scenes created in the cabin.
