A lighting fixture with a levitation function, comprising:
- a housing internally equipped with a power supply module, the power supply module comprising a magnetic field generating unit and a wireless power supply transmitting unit, wherein the housing comprises an outer shell, a top cover, and a base plate, and the housing forms a sealed cavity composed of the outer shell, the top cover embedded at a top and a detachable base plate at a bottom, wherein the sealed cavity is horizontally provided with a connecting plate fixed to an inner wall of the outer shell;
- and
- a lamp holder internally equipped with a lighting module, the lighting module comprising a magnetic field responding unit, a wireless power supply receiving unit and a light emitting unit;
- wherein the magnetic field generating unit comprises at least one electromagnetic coil and at least one first magnet, and the magnetic field responding unit comprises at least one second magnet;
- when the at least one electromagnetic coil is energized, a magnetic field is generated to provides a repulsive force to the at least one second magnet, and the at least one first magnet and the at least one second magnet have opposite magnetic poles, providing an attractive force, thereby enabling the lamp holder to levitate above the housing and maintain balance;
- wherein the wireless power supply transmitting unit comprises a wireless power supply coil, the wireless power supply receiving unit comprises a wireless receiving coil, and the wireless power supply coil and the wireless receiving coil are coupled through electromagnetic induction to supply power to the light emitting unit.
