Abstract
A method for providing light to a room that has a wall includes arranging in the room a light source having a light intensity control device, providing a model for light intensity simulating light conditions in a first period of a day, and operating the light intensity control device in accordance with the model so that light is provided to the room. Further, a system for providing illumination in a room that has a wall includes a light source having one or more individual light sources. The light source of the system also has a light controlling device for controlling intensity and/or direction of light and/or color of light emitted. The system further includes a controller device that controls the light controlling device in accordance with a simulation program simulating changes in daylight over a period of time.
