    摘要: The present invention relates to a lighting device (100) capable of creating dynamic color shadows. The lighting device (100) comprises multiple light sources (104, 105, 106) of different colors arranged to, together as a unit, emit white light. Furthermore, a contrast producing element (110) receives the emitted light and comprises portions (114) which may block light such that a shadow can be created on an object (122) behind the contrast producing element. A control unit (116) controls the light sources to modulate a spatial light spectral distribution if a selector is in an active state, or if the control unit is in an inactive state, white light is emitted by the lighting device. Thus, the lighting device is switchable between creating dynamic color shadows on objects while emitting white light, and only emitting white lights.
