As shown in fig. 1 and fig. 2, fig. 1 schematically illustrates a maglev lamp 100 provided in an embodiment of the present application, which includes a base 10 and a lamp body 20. The base 10 includes a lamp holder 11, a power module 110, a magnetic field generating device 111, and a wireless power supply transmitting module 112; the lamp body 20 includes a connecting base 21, a magnetic field induction device 210, a wireless power receiving module 211, an energy storage module 212, and an illumination module 213. The power module 110, the magnetic field generating device 111 and the wireless power supply transmitting module 112 are all arranged on the lamp holder 11; the magnetic field induction device 210, the wireless power receiving module 211, the energy storage module 212 and the illumination module 213 are disposed on the connecting seat 21. The magnetic field inducing means 210 cooperates with the magnetic field generating means 111 by magnetic force to enable the lamp body 20 to be levitated with respect to the lamp socket 11. The illumination module 213 is coupled to the wireless power receiving module 211 and the energy storage module 212 to receive the electric energy of the wireless power receiving module 211 and the energy storage module 212.
The lamp holder 11 can be understood as an outer shell of the base 10, and the shape of the lamp holder 11 can be any shape, which can be designed according to the needs of the user and is not limited in detail herein. For example, the lamp base 11 can be designed as a ring, triangle, pentagram, etc. The connection seat 21 may also be understood as a housing of the lamp body 20, and the shape of the connection seat 21 may also be any shape, which may be designed according to the user's needs, and is not particularly limited herein. For example, the connection socket 21 may be designed in a drop shape, a spherical shape, a cloud shape, or the like.
The power module 110 is coupled to the wireless power transmitting module 112 and outputs a power signal to the wireless power transmitting module 112 to supply power to the wireless power transmitting module 112. The wireless power supply transmitting module 112 is coupled to the wireless power supply receiving module 211, and the wireless power supply transmitting module 112 transmits the wireless power supply signal to the wireless power supply receiving module 211 after receiving the power supply signal. Further, the wireless power receiving module 211 is coupled to the lighting module 213, and the wireless power receiving module 211 is used for supplying power to the lighting module 213.
The lighting module 213 includes a lighting control circuit 2131 and a light emitting member 2132. The lighting control circuit 2131 is used for adjusting the light emitting parameters and the on-off state of the light emitting element 2132. The light emitting parameters of light emitting element 2132 may include, but are not limited to: brightness, color temperature, and color. In this embodiment, the light emitting element 2132 includes a plurality of light emitting diodes with different colors. The illumination control circuit 2131 controls the light emitting parameters of the light emitting element 2132, such as brightness, color temperature, and color, by changing the current or voltage of the light emitting diodes and controlling the on-off state of each light emitting diode. It is understood that in some embodiments, light emitter 2132 can be other light emitting elements.
Further, the energy storage module 212 is coupled to the illumination module 213, and the energy storage module 212 can also supply power to the illumination module 213. Specifically, the energy storage module 212 is coupled to the lighting control circuit 2131. In this embodiment, the energy storage module 212 is a rechargeable battery. The wireless power receiving module 211 is further coupled to the energy storage module 212, and the energy storage module 212 stores the electric energy provided by the wireless power receiving module 211; when the power of the energy storage module 212 is insufficient, the wireless power receiving module 211 is further configured to supply power to the energy storage module 212, so as to ensure sustainable use of the energy storage module 212.
In this embodiment, the magnetic field generator 111 includes an electromagnet 1111 and a magnetic field control module 1112 coupled to the electromagnet 1111. The electromagnet 1111 includes an electric coil coupled to the power module 110 for generating a magnetic field, and a magnetic core. The magnetic field control module 1112 is coupled between the power module 110 and the electromagnet 1111 for controlling the magnitude of the magnetic field strength generated by the electromagnet 1111. Specifically, the magnetic field control module 1112 controls the magnitude of the magnetic field strength generated by the electromagnet 1111 by varying the magnitude of the current input to the energized coil. The magnetic field induction device 210 is a permanent magnet, wherein the permanent magnet may be a magnet, or an artificial magnetic steel, and the specific material is not limited. The direction of the magnetic field generated by the permanent magnet is opposite to that of the magnetic field generated by the electromagnet 1111, so that a repulsive magnetic force is generated between the permanent magnet and the electromagnet 1111, and the lamp body 20 can be suspended relative to the base 10. Further, the magnetic field control module 1112 changes the magnitude of the magnetic field generated by the electromagnet 1111 by changing the magnitude of the current input to the energized coil, and further changes the magnitude of the repulsive magnetic force generated between the permanent magnet and the electromagnet 1111, thereby achieving the purpose of adjusting the suspension height of the lamp body 20.
Further, when the suspension height of the lamp body 20 is within the distance range of the wireless power supply, the lighting module 213 can be powered by the wireless power supply, that is, the lighting module 213 is powered by the wireless power supply receiving module 211; when the suspension height of the lamp body 20 is out of the distance range of the wireless power supply, the lighting module 213 is powered by the energy storage power supply mode, that is, the lighting module 213 is powered by the energy storage module 212, so that the limitation of the suspension height of the lamp body 20 is removed.
In a specific implementation scenario, after the lamp body 20 releases the suspension height limitation, the magnetic field control module 1112 may control the magnitude of the current input to the coil to change the suspension height of the lamp body 20. When the suspension height of the lamp body 20 is repeatedly changed for a certain period of time, the lamp body 20 may float up and down with respect to the base 10, thereby improving the enjoyment and interest of the magnetic suspension lamp.
In some embodiments, the magnetic field generating device 111 may be a permanent magnet, wherein the permanent magnet may be a magnet, or an artificial magnetic steel, and the specific material is not limited. At this time, since the magnetic field generating device 111 and the magnetic field sensing device 210 are both permanent magnets, and the magnetic field generated by the permanent magnets is relatively stable, the floating height of the lamp body 20 is not easily floated. It is understood that, although the floating height of the lamp body 20 is not floated, since the floating height of the lamp body 20 is not limited, that is, the distance between the lamp body 20 and the base 10 is not limited, the user can actively change the distance between the lamp body 20 and the lamp socket 11.
In a specific implementation scenario, the user may move the lamp body 20 away from the lamp socket 11, and the lighting module 213 may still be in the lighting state. For example, the user can carry the lamp body 20 away from the base 10, and then change the spatial positions of the lamp body 20 and the base 10, and the lamp socket 11 is still located at the original position, and at this time, the lighting module 213 can still be in the lighting state, so that the interactivity between the maglev lamp and the user is improved.
In some embodiments, the magnetic field generating device 111 may include a permanent magnet and an electromagnet 1111, and by the simultaneous action of the permanent magnet and the electromagnet 1111, the magnetic force generated between the magnetic field generating device 111 and the magnetic field sensing device 210 can be made larger, so that the lamp body 20 can reach a higher suspension height only by a smaller current, thereby saving electric energy.
Further, the magnetic levitation lamp further comprises a distance measurement module 113 and a wireless communication module 214. In this embodiment, the distance measuring module 113 is disposed on the lamp holder 11, and the distance measuring module 113 is coupled to the magnetic field control module 1112. The distance measuring module 113 is used for detecting a distance between the base 10 and the lamp body 20, so that the magnetic field control module 1112 controls the magnetic field strength of the electromagnet 1111 to the target distance according to the current distance between the base 10 and the lamp body 20. Specifically, the distance measuring module 113 presets a target distance, when the distance measuring module 113 detects that the distance between the lamp body 20 and the base 10 is inconsistent with the target distance, the distance measuring module 113 outputs a distance correction feedback signal to the magnetic field control module 1112, and further the magnetic field control module 1112 adjusts the magnitude of the current input to the electromagnet 1111 to change the magnitude of the magnetic field generated by the electromagnet 1111, so as to correct the distance between the lamp body 20 and the base 10 to the target distance, thereby accurately controlling the height at which the lamp body 20 floats, and at this time, the situation that the height at which the lamp body 20 floats is affected by environmental factors can be avoided.
In a specific implementation scenario, since the suspension height of the lamp body 20 is influenced by gravity factors of the lamp body 20, such as dust accumulation on the lamp body 20, artificial downward pressure applied to the lamp body 20, placement of an object on the lamp body 20 by a user, etc., when the gravity of the lamp body 20 changes, the suspension height of the lamp body 20 changes accordingly, and deviates from the target distance originally set by the user. At this time, the distance measuring module 113 outputs a distance correction feedback signal to the magnetic field control module 1112, so that the magnetic field control module 1112 increases the current input to the electromagnet 1111, and further increases the repulsive magnetic force between the electromagnet 1111 and the permanent magnet until the distance between the lamp body 20 and the base 10 is restored to the target distance.
Further, the target distance may be determined according to a user operation, that is, the user may freely adjust the target distance of the ranging module 113. The user can repeatedly move the lamp body 20 between the first target distance and the second target distance by setting the first target distance and the second target distance. The distance correction feedback signal output by the distance measuring module 113 at this time enables the moving distance of the lamp body 20 to be more accurate, thereby improving the moving stability of the lamp body 20.
In some embodiments, the distance measuring module 113 may be disposed on the connection base 21. The ranging module 113 may then send a range correction feedback signal to the solenoid control module on a wireless basis. The Wireless mode may be based on bluetooth, Wireless Fidelity (Wi-Fi), etc.
Further, the power module 110 is coupled to the ranging module 113, and the power module 110 is configured to provide power for the ranging module 113.
The wireless communication module 214 is disposed on the connection base 21, and is coupled to the illumination module 213, the wireless power receiving module 211 and the energy storage module 212. Specifically, the wireless communication module 214 is coupled to the lighting control circuit 2131, the wireless power receiving module 211 and the energy storage module 212, and the wireless communication module 214 is configured to output a first control signal to the lighting control circuit 2131, so that the lighting control circuit 2131 adjusts the light emitting parameters of the light emitting element 2132 according to the first control signal. When the lighting module 213 is powered by the wireless power receiving module 211, the wireless communication module 214 is configured to output a second control signal to the wireless power receiving module 211, so that the wireless power receiving module 211 controls the lighting module 213 to supply power according to the second control signal. When the lighting module 213 is powered by the energy storage module 212, the wireless communication module 214 is configured to output a third control signal to the energy storage module 212, so that the energy storage module 212 controls the power supply of the lighting module 213 according to the third control signal.
Further, the wireless communication module 214 may be connected to a mobile terminal or a fixed terminal. The connection mode may include, but is not limited to, a bluetooth connection, a Wireless Fidelity (Wi-Fi) connection, and a short-range Wireless communication technology (ZigBee) connection. Further, the wireless communication module 214 may be directly connected to a mobile terminal or a fixed terminal. In some embodiments, the wireless communication module 214 may be connected to a mobile terminal or a fixed terminal through a gateway. Specifically, the wireless communication module 214 is connected to the gateway through the ZigBee, and is further connected to a mobile terminal or a fixed terminal connected to the gateway. Further, the gateway can be connected to the cloud, and remote communication can be achieved through the cloud wireless communication module 214, so that the user can conveniently control the gateway.
Further, a user can issue a control command to the wireless communication module 214 through the mobile terminal or the fixed terminal, so that the wireless communication module 214 outputs a first control signal to the lighting control circuit 2131, and the lighting control circuit 2131 controls the current or the voltage of the light emitting element 2132 to adjust the light emitting parameters of the light emitting element 2132; or the user issues a control instruction to the wireless communication module 214 through the mobile terminal or the fixed terminal, so that the wireless communication module 214 outputs a second control signal to the wireless power supply receiving module 211, and the wireless power supply receiving module turns off or turns on the power supply of the lighting module 213, thereby controlling the on-off state of the light-emitting element 2132, that is, the on-off state of the magnetic levitation lamp 100; or the user issues a control command to the wireless communication module 214 through the mobile terminal or the fixed terminal, so that the wireless communication module 214 outputs a third control signal to the energy storage module 212, and the energy storage module 212 switches off or on the power supply of the lighting module 213, thereby controlling the on/off state of the light-emitting element 2132, that is, the on/off state of the maglev lamp 100.
In some embodiments, the wireless communication module 214 may be connected to a smart device to enable interaction with the smart device. Specifically, the wireless communication module 214 may be connected to the gateway through the ZigBee, and then connected to the smart device connected to the gateway. Further, the smart device may issue a control command to the wireless communication module 214 according to the ambient information or the preset information to control the lighting parameters and the on/off state of the light emitting element 2132.
Further, the wireless power receiving module 211 is coupled to the wireless communication module 214, and the wireless power receiving module 211 can also supply power to the wireless communication module; the energy storage module 212 is coupled to the wireless communication module and can also supply power to the wireless communication module.
The magnetic levitation lamp provided by the embodiment of the application can be powered by the lighting module by switching one of the power supply modes between wireless power supply and energy storage power supply at any time through the wireless power supply receiving module and the energy storage module, so that the magnetic levitation lamp can reach a higher levitation height, and the limitation of the wireless power supply on the levitation height of the magnetic levitation lamp is removed.

As shown in fig. 3, based on the magnetic levitation lamp 100 provided by the present application, an embodiment of the present application further provides another control method 200 for a magnetic levitation lamp, which is applied to the magnetic levitation lamp 100 described above, and the method may include the following steps S1 to S3.
Step S1: and acquiring a user instruction, and controlling the wireless power supply receiving module to supply power to the lighting module according to the user instruction, or controlling the energy storage module to supply power to the lighting module according to the user instruction.
In this embodiment, the wireless communication module obtains a user instruction, and controls the wireless power supply receiving module to supply power to the lighting module according to the user instruction, or controls the energy storage module to supply power to the lighting module according to the user instruction.
In the embodiment, the wireless communication module is equivalent to a main control chip and can be directly connected with a mobile terminal of a user through Bluetooth and Wi-Fi; or the mobile terminal is connected with the gateway through Bluetooth, Wi-Fi and ZigBee and then connected with the mobile terminal of the user.

For example, if the information carried by the user instruction is wireless power supply and the current power supply mode of the lighting module supplies power to the energy storage module, the wireless communication module sends a second control signal to the wireless power supply receiving module so that the wireless power supply receiving module starts power supply to the lighting module; and the wireless communication module sends a third control signal to the energy storage module to disconnect the power supply of the illumination module by the energy storage module.
Further, the wireless communication module can detect and acquire the current power supply mode of the lighting module. In this embodiment, the wireless communication module further determines the current power supply mode of the lighting module by reading the output current or the output voltage of the wireless power supply receiving module and the energy storage module.

Further, when the lighting module is in a lighting working state and the current electric quantity of the energy storage module is lower than the electric quantity upper limit threshold value, the wireless communication module sends a charging signal to the wireless power supply receiving module so that the wireless power supply receiving module charges the energy storage module. It is worth noting that, at this time, the wireless power supply receiving module charges the energy storage module on the premise of ensuring that the illumination module is in the illumination working state.
Further, when the lighting module is in a lighting working state and the current electric quantity of the energy storage module is not lower than the electric quantity upper limit threshold, that is, the current electric quantity of the energy storage module is full at the moment, the energy storage module does not need to be charged. At the moment, the wireless communication module sends a power supply signal to the wireless power supply receiving module, so that the wireless receiving module keeps supplying power for the energy storage module to keep the illumination module in an illumination working state.
Further, when the lighting module is not in a lighting working state and the current electric quantity of the energy storage module is lower than the electric quantity upper limit threshold value, the wireless communication module sends a charging signal to the wireless power supply receiving module so that the wireless power supply receiving module charges the energy storage module. It should be noted that the lighting module is not in the lighting operation state at this time only indicates that the input current of the light emitting element is turned off, and the lighting control circuit can still operate normally.
Further, when the lighting module is not in a lighting working state and the current electric quantity of the energy storage module is not lower than the electric quantity upper limit threshold, the wireless communication module sends a standby signal to the wireless power supply receiving module, so that the wireless power supply receiving module keeps the lighting control circuit working normally and cuts off the input current of the light emitting element.
Step S3: when the energy storage module supplies power to the lighting module, the electric quantity of the energy storage module is obtained, if the electric quantity of the energy storage module is lower than a charging threshold value, the output power of the energy storage module is reduced, or the wireless receiving module is controlled to supply power to the energy storage module.
In this embodiment, when the energy storage module supplies power to the lighting module, the wireless communication module acquires the electric quantity of the energy storage module, and if the electric quantity of the energy storage module is lower than the charging threshold, the output power of the energy storage module is reduced, or the wireless receiving is controlled to supply power to the energy storage module.
Specifically, when the energy storage module supplies power to the illumination module, the wireless communication module reads the working state of the illumination module and judges whether the illumination module is in the illumination working state; and acquiring the electric quantity of the energy storage module, and judging whether the electric quantity of the energy storage module is lower than a charging threshold value. For example, the charge threshold may be, but is not limited to: 20% electricity, 10% electricity, 5% electricity, etc.
Further, the wireless communication module judges whether the wireless communication module is in a lighting working state or not by reading the current or the voltage of the lighting module in real time; and judging whether the electric quantity of the energy storage module is lower than the charging threshold value or not by reading the current electric quantity value of the energy storage module in real time and comparing the current electric quantity value with the preset charging threshold value.
Further, when the illumination module is in the illumination operating condition and the electric quantity of energy storage module is less than the threshold value of charging, also when the electric quantity of energy storage module is less than warning level, wireless communication module exports the low light signal to energy storage module, makes energy storage module reduce the electric current of exporting to illumination module, weakens illumination brightness of illumination module according to the low light signal, and then reduces energy storage module's output, makes energy storage module can last the journey for a longer time. Furthermore, the wireless communication module also sends out reminding information, such as an indicator light or a buzzer and the like. In some embodiments, the wireless communication module can send the reminding signal to the mobile terminal of the user in a Bluetooth mode, a Wi-Fi mode, a ZigBee mode and the like, so as to remind the user.
In some embodiments, if the suspension height of the lamp body is within the distance range of the wireless power supply, the wireless communication module can output a charging signal to the wireless power supply receiving module, so that the wireless power supply receiving module directly charges the energy storage module. In some embodiments, if the suspension height of the lamp body is greater than the maximum distance of wireless power supply, the wireless communication module can communicate with the magnetic field control module through bluetooth or Wi-Fi, the wireless communication module sends a wireless signal to the magnetic field control module, so that the magnetic field control module reduces the current of the input electromagnet, the suspension height of the lamp body is reduced to a distance range of wireless power supply, and the wireless communication module outputs a charging signal to the wireless power supply receiving module to charge the wireless power supply receiving module for energy storage.
It is understood that in some embodiments, when the lighting module is in the lighting operation state and the charge of the energy storage module is lower than the charging threshold, the energy storage module can be charged while the output power of the energy storage module is reduced. Specifically, if the suspension height of the lamp body is within the distance range of wireless power supply, the wireless communication module simultaneously outputs a weak light signal to the energy storage module and outputs a charging signal to the wireless power supply receiving module, so that the wireless power supply receiving module also charges the energy storage module while the energy storage module reduces the output power; if the suspension height of the lamp body is larger than the maximum distance of wireless power supply, the wireless communication module simultaneously outputs a weak light signal to the energy storage module and sends a wireless signal to the magnetic field control module, the energy storage module reduces the output power to reduce the illumination intensity of the illumination module, the magnetic field control module enables the suspension height of the lamp body to be reduced to the distance range of the wireless power supply, and the wireless communication module outputs a charging signal to the wireless power supply receiving module again to enable the wireless power supply receiving module to charge for energy storage.
Further, when the lighting module is in the lighting working state and the electric quantity of the energy storage module is higher than the charging threshold value, the wireless communication module sends a power supply signal to the energy storage module, so that the energy storage module can supply power to the energy storage module to enable the lighting module to be kept in the lighting working state.
Further, when the lighting module is not in a lighting working state and the electric quantity of the energy storage module is lower than a charging threshold value, the wireless communication module sends a charging signal to the wireless power supply receiving module so that the wireless power supply receiving module charges the energy storage module. It should be noted that the illumination module is not in the illumination working state at this time only indicates that the input current of the light emitting element is turned off, and the illumination control circuit can still work normally.
Further, when the lighting module is not in the lighting working state and the electric quantity of the energy storage module is higher than the charging threshold value, the wireless communication module sends a standby signal to the energy storage module, so that the energy storage module keeps the normal work of the lighting control circuit to cut off the input current of the light emitting element.

In this embodiment, the distance threshold is a limit distance of wireless power supply. When the wireless power supply receiving module supplies power to the lighting module, if the relative distance between the lamp body and the base is larger than or equal to the distance threshold value, the wireless power supply signal transmitted by the wireless power supply transmitting module and acquired by the wireless power supply receiving module is insufficient, so that the current output from the wireless power supply receiving module to the lighting module can be gradually reduced to disappear, at the moment, the wireless communication module can immediately acquire the current output state of the wireless power supply receiving module, when the current output state of the wireless power supply receiving module acquired by the wireless communication module is abnormal, the wireless communication module immediately sends a third control signal to the energy storage module, and the energy storage module is switched to supply power to the lighting module.
