The present disclosure relates to a lighting device simulating visual effect of candle flame includes an immovable assembly and a movable assembly. The immovable assembly has a stationary supporting structure for holding a light source in position. The movable assembly has a light-effect component for simulating visual effect of natural flame at a candle wick. The movable assembly further includes at least a part of a driving component accommodated in the supporting structure. The part of the driving component and the light-effect component of the movable assembly are such connected to each other that when the part of the driving component moves positively and/or is driven to move passively, at least a part of the light-effect component performs swing movement. The lighting device thus can simulate naturally flickering or dancing flame of a burning candle, thereby creating lighting effect and atmosphere as those provided by a real candle.
