Abstract
A lighting device comprising at least three LED chains, each LED chain including a plurality of LED light sources separated from each other along the LED chain, wherein the LED light sources of each LED chain are electrically connected to a common drive signal line, wherein the light sources of the at least three LED chains are substantially evenly and non-symmetrically distributed over a light area, and a controller configured to apply a different drive signal to each drive signal line, wherein each drive signal is time varying so as to cause a time variation of at least one property of light emitted from the LED light sources. By applying different, and dynamically changing drive signals to the three groups, lighting effects resembling those occurring in nature can be accomplished, at a fraction of the costs of a pixelated and addressable device.
