Abstract: The present invention relates to a dynamic lighting device, including at least two lamps and a base. Each of the at least two lamps is connected to a respective paired flexible stalk configured to rotate in a circumferential direction of the base. When the flexible stalks rotate in the circumferential direction of the base, due to dynamic bending deformation of the flexible stalks, the at least two lamps have random movement in an upright direction and the at least two lamps have circumferential random wiggles against a joint defined between the flexible stalks and the base as a pivotal point.

Abstract: The present disclosure relates to a fountain device including: a fountain core and a floating portion. The fountain core includes a hydraulic portion and a power supply for providing power to the hydraulic portion and is configured to pump water from a water inlet at a lower portion by means of the hydraulic portion and spraying water via a water spout at an upper portion to form a fountain. The floating portion is configured to cause the fountain device to float in the water and forms a core mounting hole for holding the fountain core when inflated with a low density fluid, so that the fountain core can form a fountain by the hydraulic portion in a state that the fountain device floats in the water.

Abstract: 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.
