The utility model provides a magnetic suspension lamps and lanterns.
In an embodiment of the present invention, referring to fig. 1 to 8, the magnetic suspension lamp 1 includes:
the wireless power supply device comprises a lamp holder 10, a wireless power supply transmitting coil 110 and a magnetic suspension module 120, wherein a first positioning piece 130 is arranged on the bottom surface of the lamp holder 10; and
the lamp holder 20 is internally provided with a permanent magnet 230, a wireless power supply receiving coil 210 and a lamp wick 220 electrically connected with the wireless power supply receiving coil 210, and the top surface of the lamp holder 10 is provided with a second positioning piece 250;
the magnetic suspension lamp 1 has a suspension state and an adsorption state, when the magnetic suspension lamp 1 is in the suspension state, a first magnetic force is generated between the magnetic suspension module 120 and the permanent magnet 230, and the first magnetic force is balanced with the self-gravity of the lamp holder 20, so that the lamp holder 20 is suspended at a preset position below the lamp holder 10; when the magnetic suspension lamp 1 is in the attraction state, a second magnetic force is generated between the magnetic suspension module 120 and the permanent magnet 230, and the second magnetic force is greater than the self-gravity of the lamp holder 20 and is balanced, so that the top surface of the lamp holder 20 is attracted and abutted to the bottom surface of the lamp holder 10, and the first positioning member 130 is matched with the second positioning member 250.
Specifically, the lamp socket 10 and the lamp cap 20 are mutually independent components, the lamp socket 10 may be fixed in the air through a wall hanging, a ceiling or a bracket fixing, and the like, the lamp socket 10 has a first housing, a wireless power supply transmitting coil 110 and a magnetic suspension module 120 are disposed in the first housing, and the wireless power supply transmitting coil 110 is connected with a power supply. The lamp head 20 has a second casing, a permanent magnet 230, a wireless power receiving coil 210 and a lamp wick 220 are disposed in the second casing, and the lamp wick 220 is electrically connected to the wireless power receiving coil 210. To facilitate the wireless power receiving coil 210 to interact with the wireless power transmitting coil 110, the wireless power receiving coil 210 is located at a top position of the second housing. In order to facilitate the interaction of the permanent magnet 230 with the above-mentioned magnetic levitation module 120 for levitating the lamp cap 20 under the lamp holder 10, the permanent magnet 230 is also located at the top position of the second housing. The wick 220 is located at the bottom position of the second housing, and the wick 220 is located below the wireless power receiving coil 210 and the permanent magnet 230. The lamp holder 10 and the lamp head 20 are powered by a wireless power supply mode, and the wireless power supply transmitting coil 110 transmits electric energy to the wireless power supply receiving coil 210 in a wireless mode, so that the lamp wick 220 is electrified and emits light, and the lighting function of the lamp head 20 is realized.
The magnetic suspension lamp 1 has a suspension state and an adsorption state, and when the magnetic suspension lamp 1 is in the suspension state, the magnetic suspension module 120 and the permanent magnet 230 generate a first magnetic force in an upward horizontal direction, and the first magnetic force is balanced with the self-gravity of the lamp head 20, so that the lamp head 20 is suspended at a preset position below the lamp holder 10 (the distance between the lamp head 20 and the lamp holder 10 is a preset range value). When the magnetic suspension lamp 1 is in a suspension state, the magnetic suspension module 120 and the permanent magnet 230 generate a second magnetic force horizontally upward, the second magnetic force is greater than the self-gravity of the lamp holder 20, so that the lamp holder 20 is forced to move upward, and the top surface of the lamp holder 20 is attracted and abutted to the bottom surface of the lamp holder 10.
It should be noted that, in this embodiment, the bottom surface of the lamp holder 10 is provided with the first positioning element 130, and the top surface of the lamp holder 20 is provided with the second positioning element 250, and when the magnetic suspension lamp 1 is switched from the suspension state to the absorption state, the first positioning element 130 and the second positioning element 250 are matched with each other, so as to ensure that the lamp holder 20 is absorbed at the same position of the lamp holder 10 at each time, and avoid the defect that the lamp holder 20 is misaligned during the absorption movement.
The technical proposal of the utility model adopts the magnetic suspension technology and the wireless power supply technology to electrify and illuminate the lamp holder 20 suspended below the lamp holder 10, thus realizing the suspended illumination effect; meanwhile, by arranging the first positioning piece 130 and the second positioning piece 250, when the magnetic suspension lamp 1 is switched from the suspension state to the adsorption state, the first positioning piece 130 and the second positioning piece 250 are matched with each other, so that the lamp holder 20 is ensured to be adsorbed at the same position of the lamp holder 10 every time, and the defect that the lamp holder 20 is dislocated during adsorption movement is avoided.
Preferably, the first positioning member 130 is disposed to be convex downward, and the second positioning member 250 is disposed to be concave upward; alternatively, the first positioning member 130 is disposed in a concave shape facing downward, and the second positioning member 250 is disposed in a convex shape facing upward. In this way, the first positioning element 130 and the second positioning element 250 are matched through the concave-convex curved surface, and the first positioning element 130 and the second positioning element 250 slide to the matching position along the curved surface profile, so that the lamp holder 20 can be relatively stable and can be positioned and adsorbed at the bottom surface of the lamp holder 10.
It should be noted that, due to the limitation of the existing wireless power supply technology, the efficiency of the wireless power supply transmitting coil 110 and the wireless power supply receiving coil 210 for transmitting electric energy is low, and the power supply power is small, so that when the lamp holder 10 wirelessly supplies power to the lamp head 20, the lamp wick 220 has low brightness due to the small power supply power.
Further, in order to overcome the problem of low light-emitting brightness of the lamp cap 20, in the present embodiment, referring to fig. 3 to 10, the bottom surface of the lamp socket 10 is further provided with a first power supply contact 140 electrically connected to a power supply; the top of the lamp cap 20 is provided with a second power supply contact 240, and the second power supply contact 240 is electrically connected with the lamp wick 220; when the lamp cap 20 is magnetically attached to the bottom surface of the lamp socket 10, the first power supply contact 140 and the second power supply contact 240 are abutted to each other to conduct, so that the power supply is directly conducted with the lamp wick 220, and power is supplied to the lamp wick 220 in a wired manner.
Thus, when the user needs to enhance the brightness of the lamp holder 20, the magnetic suspension lamp 1 is switched from the suspension state to the adsorption device, at this time, the wick 220 supplies power in a wired conduction manner between the first power supply contact 140 and the second power supply contact 240 in addition to the wireless power supply between the wireless power supply transmitting coil 110 and the wireless power supply receiving coil 210, at this time, the power supply power of the wick 220 is increased, and the brightness of the wick 220 is also improved.
It can be understood that, due to the existence of the first positioning member 130 and the second positioning member 250, the lamp cap 20 can be attracted to the fixed position of the lamp holder 10, and thus, the first power supply contact 140 and the second power supply contact 240 can be precisely abutted to achieve electrical conduction.
Further, the first power supply contact 140 includes a first sub-contact 141 and a second sub-contact 142, the first sub-contact 141 is disposed in a central region of the bottom surface of the lamp socket 10, and the first sub-contact 141 is disposed in a downwardly convex shape; the second power supply contact 240 includes a third sub-contact 241 and a fourth sub-contact 242, the third sub-contact 241 is disposed in a concave shape facing upward, the third sub-contact is located in a central region of the top surface of the base 20, the fourth sub-contact 242 is disposed in a ring shape around the third sub-contact 241, and a distance between the first sub-contact 141 and the second sub-contact 142 is the same as a distance between the third sub-contact 241 and the fourth sub-contact 242; when the magnetic levitation lamp 1 is in the attraction state, the first sub-contact 141 and the third sub-contact are in mutual contact and conduction, and the second sub-contact 142 and the fourth sub-contact are in mutual contact and conduction. Wherein one of the first and second sub-contacts 141 and 142 is a positive electrode and the other is a negative electrode. With the above configuration, even when the base 20 horizontally rotates around the axis with respect to the socket 10 when the magnetic levitation lamp 1 is in the attraction state, the first power supply contact 140 and the second power supply contact 240 can be always kept in contact with each other.
In some specific implementations, the structure of the first positioning element 130 may be combined with the structure of the first sub-contact 141, and the structure of the second positioning element 250 may be combined with the structure of the third sub-contact 241, that is, the first sub-contact 141 forms the first positioning element 130, and the third sub-contact 241 forms the second positioning element 250. Therefore, the first positioning member 130 and the second positioning member 250 can be reduced from being additionally arranged, so that the structures of the lamp cap 20 and the lamp holder 10 are simplified, and the production cost of the product is reduced.
Further, the magnetic levitation module 120 includes an iron core 121 and a magnetic coil 122 disposed around the iron core 121, and a first magnetic attraction force is generated between the iron core 121 and the permanent magnet 230; when the magnetic suspension lamp 1 is in a suspension state, the lamp holder 20 is located below the lamp holder 10, the distance between the lamp holder 20 and the lamp holder 10 is a preset range value, the magnetic coil 122 is electrified to generate a first magnetic repulsion force mutually repelling with the permanent magnet 230, and the first magnetic repulsion force and the first magnetic attraction force act to form a first magnetic force; when the magnetic coil 122 is powered off, the first magnetic repulsion force disappears, and the first magnetic attraction force forms a second magnetic force, so that the magnetic suspension lamp 1 is switched from the suspension state to the attraction state.
It is understood that the magnetic coil 122 and the core 121 form an electromagnet structure. For the electromagnet, the magnitude of the magnetic force generated by the magnetic coil 122 can be changed by changing the magnitude of the current of the magnetic coil 122, and the magnetic pole generated by the magnetic coil 122 can be changed by changing the direction of the current of the magnetic coil (i.e., the magnetic force is in the opposite direction).
It should be noted that, no matter whether the magnetic coil 122 is energized or not, the permanent magnet 230 located in the lamp base 20 interacts with the iron core 121 in the lamp holder 10 to generate a magnetic attraction effect, i.e. the permanent magnet 230 receives an upward first magnetic attraction force. When the lamp cap 20 is located at the predetermined position below the lamp holder 10, the first magnetic attraction is larger than the gravity of the lamp cap 20 itself, and further, when there is no other acting force, the lamp cap 20 is attracted upward to the bottom surface of the lamp holder 10 from the predetermined position below the lamp holder 10.
Under the normal power-on condition, when the lamp holder 20 is located at the preset position below the lamp holder 10 (the distance between the lamp holder 20 and the lamp holder 10 is a preset range value), the magnetic coil 122 is powered on to generate a first magnetic repulsion force capable of repelling the permanent magnet 230 downwards, the sum of the first magnetic repulsion force and the self gravity of the lamp holder 20 is equal to the first magnetic attraction force, and further when the lamp holder 20 is located at the preset position below the lamp holder 10, the stress of the lamp holder 20 in the vertical direction is balanced, so that the lamp holder 20 can be suspended at the preset position below the lamp holder 10, and the suspension effect of the lamp holder 20 is realized.
When the magnetic coil 122 is powered off, the first magnetic repulsion force disappears at this time, and the first magnetic attraction force is greater than the gravity of the lamp cap 20 itself, so that the lamp cap 20 is upwardly attracted to the bottom surface of the lamp holder 10 from the preset position below the lamp holder 10, and the lamp cap 20 is prevented from falling and being damaged.
Further, the lamp socket 10 further includes a hall sensor 150 and a controller, wherein: the hall sensor 150150 is arranged in the lamp holder 10, and the hall sensor 150 is used for detecting the distance between the permanent magnet 230 and the lamp holder 10; the controller is connected to the hall sensor 150, and when the hall sensor 150 detects that the lamp head 20 is located at the preset position, the controller controls the magnetic coil 122 to generate a first magnetic repulsion force.
The hall sensor 150 detects the position of the surrounding magnet through the "hall effect" principle, in this embodiment, the hall sensor 150 capable of detecting the permanent magnet 230 is arranged in the lamp holder 10, the hall sensor 150 is capable of detecting whether the lamp holder 20 is arranged below the lamp holder 10 (the permanent magnet 230 is arranged in the lamp holder 20), and the distance between the lamp holder 20 (the permanent magnet 230 is arranged in the lamp holder 20) and the lamp holder 10. When the lamp holder 20 is located at a preset position below the lamp holder 10 (the distance between the lamp holder 20 and the lamp holder 10 is a preset range value), the hall sensor 150 sends a position signal to the controller, and the controller controls the direction and magnitude of the energizing current of the magnetic coil 122 according to the position, so that the magnetic coil 122 generates the first magnetic repulsion force, and the suspension effect of the lamp holder 20 is further realized.

The power supply module 410, the wireless power supply transmitting coil 110 and the magnetic coil 122 are connected by wires, and the wires may be hidden inside the connecting rod assembly 30 or fixed along the surface of the connecting rod assembly 30.
