It not only provides lighting for home, business and other places, but also serves as a distinctive decoration to create a dreamy and technological atmosphere.

[0003] However, the existing magnetic suspension small lamp has some deficiencies in actual use, such as poor stability of the traditional magnetic suspension lamp base. When subjected to external forces such as collision, it is easy to produce sudden and rapid displacement, which will make the relative position of the base and the magnet of the magnetic suspension lamp body deviate from the balance position instantaneously, resulting in dramatic changes in the magnetic field force. Once the magnetic suspension system fails to compensate in time, for example, the electromagnet power is insufficient or the control algorithm is lagging, the magnetic suspension lamp body may fall due to the loss of support force, causing damage. In addition, some magnetic suspension small lamps lack effective restriction of the activity range of the lamp body, which may accidentally fall out of the base during suspension, resulting in damage. Therefore, a magnetic suspension small lamp is needed to solve the problems in the prior art. SUMMARY

Before use, press the base downward, and the positioning suction disc is adsorbed on the desktop. And due to the rotating block maintaining a set angle under the torsional force of the torsional spring, the rotating block with torsional limiting force can enhance the holding effect of the positioning suction disc adsorption position, reducing the possibility of sudden displacement of the base due to collision, thereby reducing the risk of magnetic levitation lamp ball falling due to displacement of the base.

[0024] Magnetic suspension principle: make use of the phenomenon that like poles repel and unlike poles attract, and that a current passing through a conductor generates a magnetic field. Install magnets or electromagnets on the base 1 and the suspended part of the magnetic suspension small lamp respectively. Through precise control of the interaction of the magnetic field, the suspended part overcomes the force of gravity and suspends in the air. Wireless power supply principle: based on the principle of electromagnetic induction, the transmitting coil in the base 1 is connected to the power supply. When electrified, it generates an alternating magnetic field. When the receiving coil of the suspended part is in this alternating magnetic field, it will induce an alternating voltage. After rectification, filtering, and adaptive processing, the alternating electric energy is converted into direct current energy, which powers the light-emitting elements of the small lamp, realizing wireless lighting in the suspended state.

[0025] The magnetic suspension lamp ball 2 usually contains light-emitting elements such as LED lamp beads, as well as permanent magnets or electromagnets, receiving coils, etc. The light-emitting elements are responsible for emitting light, while the permanent magnets or electromagnets interact with the corresponding part of the base 1 to achieve suspension, and the receiving coil is used to receive the wirelessly transmitted electric energy.

[0026] The base 1 mainly has a power interface, a control circuit, a transmitting coil and a permanent magnet or an electromagnet, etc. The power interface is used for connecting an external power supply to provide power for the whole device; the control circuit is responsible for controlling the magnetic field strength, the current size, etc. to realize the control of the suspension state and the light effect; the transmitting coil is used for converting electric energy into magnetic field energy to transmit energy to the suspended part; and the permanent magnet or the electromagnet interacts with the corresponding part of the suspended part to generate a suspension force.
