Candle-shape decorative lamp

A candle-shape decorative lamp, comprising:

• an aquatic lamp main body, being a three-dimensional object formed by a light-transmittable hollow main body and a light-transmittable bottom cover, sealing a fluid with slightly high viscosity;
• a magnet-driven element, disposed inside the aquatic lamp main body, having a spherical bottom and radiating flip plates at the top;
• a buoy, having a surface forming a hollow cylinder disposed with a pattern, having a plurality of rotational plates disposed with interval at the top and the bottom of the buoy, the buoy being disposed inside the aquatic lamp main body;
• a bottom base, having an upward opening fixedly engaged to the aquatic lamp main body, being disposed with at least a light-emitting element corresponding to the bottom of the aquatic lamp main body, inside being disposed with a magnetic rotational axis correspondingly attached to the magnet-driven element, the magnetic rotational axis being driven to rotate by a driving element;
• a three-dimensional cover body, assembled and disposed to the top of the aquatic lamp main body;
• and
• a shade, being hollow and disposed over the top of the cover body and accommodating a light-emitting element inside;
• wherein when the magnetic rotational axis being in rotation, the magnet-driven element also rotating because of attachment to the magnetic rotational axis so as to wave the fluid inside the aquatic lamp main body, which leading to pushing to rotational plats to rotate the buoy so that the light emitted through the aquatic lamp main body forming ambient light with decorative effect so as to great rich and fun visual effects.
