The present invention relates to an illumination device (1) for providing a controllable illumination configuration. The illumination device comprises a light-source unit (2; 20) comprising a plurality of individually controllable solid state light-sources (8); and an optical element (3) arranged to modulate light from the solid state light-sources through a modulation area (16) of the optical element (3). The illumination device (1) further comprises an actuator (4) connected to the light-source unit (2) and controllable to move the light-source unit relative to the optical element (3) in such a way that the solid state light-sources (8) pass the modulation area (16) of the optical element (3) in succession; and a control unit (5) configured to control each of the solid state light-sources (8) to emit light with a time-varying intensity corresponding to the illumination configuration while the solid state light-source (8) moves past the modulation area of the optical element.
