Abstract
A device for changing the passage of light through a window, especially through a transparent cover of a motor vehicle roof toward the motor vehicle interior, by at least two strip-shaped grid structures which are arranged to be able to move on top of one another. In order to achieve adjustable light effects, especially in a motor vehicle interior, at least one grid structure is formed from alternately transparent and opaque strips and another grid structure is formed from at least two colored strips of different color in a repeating sequence and the mutual positioning of the grid structures can be set by an actuating means.
