Abstract: A whirlpool type aqua-lamp-based candle-like lighting device includes a stand accommodating therein a motor for driving rotation of a magnetic piece and an aqua lamp that defines a chamber mounted to an open end of the stand. The aqua lamp receives therein a magnetically-driven moving piece located on a bottom thereof and corresponding to the magnetic piece and a light generation assembly is set under the aqua lamp. An illuminator for generating twinkling lighting is arranged at an opening of the chamber. Thus, the motor, once set in operation, rotates the magnetically-driven moving piece, which in turn causes a liquid flow inside the aqua lamp in a whirlpool and dazzling/shining manner; meanwhile, the illuminator on the chamber provides a function of simulating a twinkling candle flaming. The whirlpool type aqua-lamp-based candle-like lighting device shows dual interests of visual effects in light twinkling and entertainment of observing liquid flowing.
