Description

Technical Field

[0001] This invention relates to the field of wireless charging, and more particularly to a wireless charging device and a wireless charging lighting system. Background Technology

[0002] Rechargeable lights require a charger or plugging them into a power source when their battery is depleted. Current rechargeable lights often use a wired contact charging method, which is cumbersome and poses significant risks during charging.

[0003] Wireless charging technology helps solve the above problems. Wireless charging involves the transfer of energy between the charger and the device using a magnetic field, such as electromagnetic induction wireless charging or magnetic resonance wireless charging. In these methods, no wires connect the wireless charger and the device, thus eliminating exposed conductive contacts. Wireless charging lamps require precise positioning at a specific location on the charging device. Misalignment can lead to low charging efficiency or even prevent charging altogether. Currently, to maintain alignment, existing wireless charging lamps typically require the lamp to be placed horizontally above the charging device. Tilting the lamp can cause instability, potentially leading to detachment and affecting charging efficiency.

[0004] To prevent instability during charging and ensure accurate placement, a magnet is typically installed below the lamp to magnetically attract it to the charging device. However, existing magnetically attracted lamps, especially work lamps, tend to attract ferrous objects such as iron filings and pieces, which are difficult to remove. Placing a lamp with these contaminants on the wireless charging device increases the distance between them, affecting power transmission efficiency and potentially preventing charging altogether. Furthermore, after charging, the strong magnetic attraction makes it difficult to separate the lamp from the charging device. When lifting the lamp, the magnets hold it together, requiring the user to hold the charging device with the other hand, causing inconvenience. Summary of the Invention

[0059] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0060] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0061] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0062] Referring to the accompanying drawings of this invention Figures 1A to 8 As shown, a wireless charging lighting system according to a first preferred embodiment of the present invention will be described below. The wireless charging lighting system includes a wireless charging device 10 and a lamp 20, wherein the lamp 20 can be magnetically attached to the wireless charging device 10, and the lamp 20 is charged when the wireless charging device 10 is powered on. The lamp 20 is magnetically attached to the wireless charging device 10, and the lamp 20 is charged by the wireless charging device 10. The wireless charging device 10 can be installed or placed on an inclined or vertical surface. The magnetic attachment of the wireless charging device 10 to the lamp 20 maintains the relative position stability of the lamp 20 and the wireless charging device 10, thereby improving the charging stability of the wireless charging lighting system. In short, the wireless charging device 10 can be installed on a wall, an inclined tabletop, or other irregularly shaped surface, wherein the lamp 20 is magnetically attached to the surface of the wireless charging device 10, and the lamp 20 is wirelessly charged by the wireless charging device 10.

[0063] like Figures 1A to 4As shown, the wireless charging device 10 includes a charging body 11 and at least one magnetic attraction device 12. The magnetic attraction device 12 is disposed on the charging body 11, and the lamp 20 is attracted to the charging body 11 by the magnetic attraction device 12. The charging body 11 wirelessly transmits electrical energy to the lamp 20 when powered on. The magnetic attraction device 12 is movably disposed on the charging body 11. By adjusting the magnetic attraction device 12, it is easy for the lamp 20 to be attracted to the charging body 11 and easy for the lamp 20 to be separated from the charging body 11. In this preferred embodiment of the invention, the magnetic attraction device 12 is rotatably disposed on the charging body 11. By rotating the magnetic attraction device 12, the relative position of the magnetic attraction device 12 and the lamp 20 is adjusted, thereby facilitating the attraction or separation of the lamp 20 from the charging body 11.

[0064] Accordingly, the magnetic attraction device 12 has a magnetic attraction surface 121, at least one non-magnetic attraction surface 122, and a rotation axis 123. The magnetic attraction surface 121 of the magnetic attraction device 12 has a magnetic attraction effect, capable of attracting magnetic metal materials such as iron, cobalt, and nickel. The non-magnetic attraction surface 122 does not attract magnetic materials. The magnetic attraction device 12 is rotated around the rotation axis 123, with the magnetic attraction surface 121 and the non-magnetic attraction surface 122 rotating based on the rotation axis 123. When the magnetic attraction surface 121 faces the lamp 20, that is, when the magnetic attraction surface 121 faces the charging direction of the charging body 11, the lamp 20 can be attracted by the magnetic attraction device 12 and adhere to the charging surface of the charging body 11. When the magnetic suction device 12 is rotated so that the non-magnetic suction surface 122 faces the lamp 20, that is, when the non-magnetic suction surface 122 faces the charging direction of the charging body 11, the lamp 20 can be separated from the surface of the charging body 11 because the non-magnetic suction surface 122 does not have a magnetic attraction effect.

[0065] Specifically, see the attached document. Figures 1A to 4 The magnetic surface 121 and the non-magnetic surface 122 of the magnetic attraction device 12 correspond to each other, so that the magnetic attraction device 12 can be driven to rotate around the rotation axis 123. Selectively, one of the magnetic surface 121 and the non-magnetic surface 122 of the magnetic attraction device 12 faces the lamp 20. When the magnetic surface 121 of the magnetic attraction device 12 faces the lamp 20, the lamp 20 can be attracted to the wireless charging device 10 by the magnetic attraction device 12. Correspondingly, when the non-magnetic surface 122 of the magnetic attraction device 12 faces the lamp 20, the magnetic attraction between the lamp 20 and the wireless charging device 10 disappears, so that the lamp 20 can be easily separated from the wireless charging device 10.

[0066] It is worth mentioning that the way the magnetic attraction device 12 is driven to rotate around the rotation axis 123 is not limited in the lighting system of the present invention. For example, the magnetic attraction device 12 can be driven to rotate around the rotation axis 123 relative to the wireless charging device 10 by manually driving the magnetic attraction device 12, or the magnetic attraction device 12 can be driven to rotate around the rotation axis 123 relative to the wireless charging device 10 by a drive motor.

[0067] The magnetic attraction device 12 further includes at least one magnetic attraction unit 124 and a support device 125, wherein the magnetic attraction unit 124 is disposed on the support device 125, and the support device 125 rotates based on the rotation axis 123. The magnetic attraction unit 124 is disposed adjacent to the magnetic attraction surface 121. Preferably, the magnetic attraction unit 124 is embedded in the support device 125, thereby forming the magnetic attraction surface 121 on one surface of the support device 125, wherein the support device 125 forms the non-magnetic attraction surface 122 corresponding to the opposite side of the magnetic attraction surface 121. It can be understood that the positions of the magnetic attraction surface 121 and the non-magnetic attraction surface 122 of the magnetic attraction device 12 can be identified by the position of the magnetic attraction unit 124.

[0068] The magnetic attraction unit 124 is a magnetic element made of permanent magnet material, such as a magnet, AlNiCo permanent magnet alloy, IronChromiumCo permanent magnet alloy, permanent magnet ferrite, rare earth permanent magnet material, and composite permanent magnet material. It is understood that the type of magnetic attraction unit 124 is merely exemplary and not limiting; therefore, the magnetic attraction unit 124 can also be implemented as an electromagnetic device. Preferably, in this preferred embodiment of the invention, the magnetic attraction unit 124 is embedded in the support device 125, and the upper surface of the magnetic attraction unit 124 and a surface of the support device 125 together form the magnetic attraction surface 121 of the magnetic attraction device 12. The support device 125 shields the magnetism of the magnetic attraction unit 124, thereby forming the non-magnetic attraction surface 122 of the magnetic attraction device 12 on the reverse side of the support device 125.

[0069] The magnetic attraction device 12 further includes at least one rotary latch 126, wherein the rotary latch 126 controls the rotation of the support device 125. The rotation shaft 123 of the magnetic attraction device 12 is brakeably connected to the rotary latch 126, thereby braking the rotation shaft 123 by the rotary latch 126, thus locking the support device 125 and preventing the support device 125 from rotating. Preferably, the rotary latch 126 is disposed on the charging body 11. When the rotary latch 126 is pressed, the rotary latch 12 stops braking the rotation shaft 123, and the support device 125 can be rotated to adjust the position of the magnetic attraction surface 121 and the non-magnetic attraction surface 122.

[0070] Preferably, in this preferred embodiment of the invention, the magnetic attraction device 12 has two or more magnetic attraction units 124, which are arranged at intervals to position the lamp 20 so that the lamp 20 is aligned with the wireless charging device 10, thereby improving the charging efficiency of the wireless charging device 10 for the lamp 20. Furthermore, by increasing the number of magnetic attraction units 124, the attraction force between the magnetic surface 121 of the magnetic attraction device 12 and the lamp 20 is increased, so that the wireless charging device 10 stably maintains the position of the lamp 20 during charging.

[0071] like Figures 1A to 4 As shown, the charging body 11 includes a housing 111, at least one transmitting module 112, a power interface 113, and a circuit board 114. The transmitting module 112 is electrically connected to an external power source via the power interface 113. The transmitting module 112 is disposed on the housing 111 and fixed to the housing 111. The transmitting module 112 transmits a charging electromagnetic signal to the lamp 20 based on the housing 111. The magnetic suction device 12 is movably disposed on the housing 111 of the charging body 11. The housing 111 includes an upper housing 1111, a lower housing 1112, and a mounting groove 1113 formed by the upper housing 1111 and the lower housing 1112. The housing 111 movably holds the magnetic suction device 12 in the mounting groove 1113. Preferably, the mounting groove 1113 is formed at the middle position of one side of the housing 111. The magnetic attraction device 12 is supported by the housing 111 and rotates within the mounting groove 1113. It is worth noting that when the magnetic attraction device 12 is rotated, it rotates within the mounting groove 1113, meaning that the magnetic attraction device 12 will not extend beyond the bottom edge of the housing 111 during rotation.

[0072] It is worth mentioning that the housing 111 of the charging body 11 has an upper surface 1117 and a lower surface 1118, wherein the upper surface 1117 is located at the upper end of the upper housing 111, and the lower surface 1118 is formed on the lower side of the lower housing 112. When the magnetic attraction device 12 rotates within the mounting groove 1113, the edge of the magnetic attraction device 12 does not extend beyond the lower surface 1118 of the housing 111.

[0073] The transmitting module 112 is disposed on the upper housing 1111 of the housing 111. Preferably, the transmitting module 112 is attached to the inner side of the upper housing 1111, so that when the lamp 20 is charging, the transmitting module 112 is close to the lamp 20, thereby improving the charging efficiency of the wireless charging device 10. The transmitting module 112 includes at least one wireless transmitting coil, wherein the wireless transmitting coil is electrically connected to the circuit board 114. It is worth mentioning that the distance between the transmitting module 112 and the magnetic attraction device 12 is greater than or equal to 7.5mm, so as to avoid the transmitting module 112 of the wireless charging device 10 being affected by the magnetic field of the magnetic attraction device 12 during operation, thereby facilitating the stable operation of the wireless charging device 10.

[0074] The housing 111 has an accommodating space 1114, wherein the upper housing 1111 and the lower housing 1112 of the housing 111 together form the accommodating space 1114, wherein the transmitting module 112 and the circuit board 114 are held by the housing 111 in the accommodating space 1114. The housing 111 further has at least two shaft holes 1115, wherein the rotating shaft 123 rotatably mounts the magnetic suction device 12 to the housing 111 through the shaft holes 1115.

[0075] The housing 111 further provides at least one mounting hole 1116, wherein the mounting hole 1116 penetrates the upper housing 1111 and the lower housing 1112 of the housing 111. The wireless charging device can be mounted on a wall surface, table, chair, or other location through the mounting hole 1116. It is understood that, in this preferred embodiment of the invention, the wireless charging device 10 can be fixedly mounted on a wall, wherein the magnetic attraction device 12 of the wireless charging device 10 can magnetically attract the lamp 20 being charged to the surface of the wireless charging device 10.

[0076] The circuit board 114 is connected to an external power source via the power interface 113, and transmits the power from the external power source to the transmitting module 112, so that the transmitting module 112 can wirelessly transmit the power from the external power source to the lamp 20. It is worth mentioning that, in this preferred embodiment of the invention, the wireless charging device 10 transmits power to the lamp 20 via electromagnetic induction through the transmitting module 112, or via magnetic resonance through the transmitting module 112. In this invention, the method of power transmission of the wireless charging device 10 is merely exemplary and not limiting.

[0077] like Figures 2 to 4 As shown, the wireless charging device 10 further includes at least one mounting unit 13, wherein the mounting unit 13 mounts the charging body 11 of the wireless charging device 10 to a mounting object, such as a desktop, iron plate, or workbench. Preferably, the mounting unit 13 mounts the wireless charging body 11 to the mounting object by adsorption or attachment. That is, the mounting unit 13 can be implemented as an adhesive element or a magnetic adsorption element. Preferably, in this preferred embodiment of the present invention, the mounting unit 13 is a magnet, wherein the mounting unit 13 is disposed on the housing 111 of the charging body 11, thereby fixing the charging body 11 to a magnetically adsorbent desktop, such as the surface of an iron object, by means of the mounting unit 13 adsorption.

Specifically, when the wireless charging device 10 is wirelessly charging the lamp 20, the wireless charging device 10 is in a charging state, and the prompting device 14 prompts the operator that the wireless charging device is currently charging the lamp 20. When the lamp 20 is fully charged, the prompting device 14 prompts the operator to promptly stop the charging process of the lamp 20, or remove the lamp 20 that has been charged.

[0079] In detail, the prompting device 14 further includes at least one warning light 141 and a buzzer 142, wherein the warning light 141 illuminates the operator to indicate the charging status of the lamp 20 or the operating status of the wireless charging device 10. The buzzer 142 audibly indicates the operator to indicate the current operating status of the wireless charging device 10. Specifically, when the lamp 20 is fully charged, the wireless charging device 10 cannot charge the lamp 20, or the wireless charging device 10 is malfunctioning, the warning light 141 or the buzzer 142 of the prompting device 14 alerts the operator so that the operator can adjust the wireless charging device 10, adjust the relative position of the lamp 20 and the wireless charging device 10, or detach the lamp 20 from above the wireless charging device 10 according to the prompt information. Preferably, the prompting device 14 is disposed on the upper housing 1111 of the housing 111. It is understood that the installation positions of the warning light 141 and the buzzer 142 of the prompting device 14 are merely illustrative and not limiting.

[0080] Referring to the accompanying drawings of this invention Figures 5A to 5C As shown, another optional embodiment of the wireless charging lighting system according to the preferred embodiment of the present invention, a wireless charging device 10A, is described below. The wireless charging device 10A includes a charging body 11A, a magnetic attraction device 12A, at least one mounting unit 13A, and at least one notification device 14A.

It is worth noting that in the present invention, the structure and function of the mounting unit 13A and the notification device 14A of the wireless charging device 10A are the same as those of the wireless charging device of the first preferred embodiment described above.

[0081] The magnetic attraction device 12A is disposed on the charging body 11A, and the magnetic attraction device 12A can be driven to move or rotate parallel to the charging body. By adjusting the position or rotation angle of the magnetic attraction device 12A, the lamp 20 is attracted to the charging body 11A and the lamp 20 is easily separated from the charging body. Specifically, the charging body 11A includes a housing 111A, at least one transmitting module 112A, a power interface 113A, and a circuit board 114A, wherein the transmitting module 112A is electrically connected to an external power source through the power interface 113A. The housing 111A of the charging body 11A has a mounting groove 1113A, wherein the magnetic attraction device 12A is disposed in the mounting groove 1113A in a relatively movable manner.

[0082] In this preferred embodiment of the invention, the magnetic position of the magnetic suction device 12A is adjusted by moving its position in the mounting groove 1113A, thereby adjusting the position where the lamp 20 is attracted. The magnetic suction device 12A has a magnetic surface 121A and at least one non-magnetic surface 122A, wherein the magnetic surface 121A and the non-magnetic surface 122A are located in the same plane or the planes containing the magnetic surface 121A and the non-magnetic surface 122A are parallel to each other. The magnetic suction device 12A is moved or rotated parallel to each other within the mounting groove 1113A by pressing or pushing, thereby changing the position of the magnetic surface 121A and the non-magnetic surface 122A relative to the charging body 11A. Exemplarily, the magnetic surface 121A of the magnetic suction device 12A is located inside the non-magnetic surface 122A. The magnetic attraction device 12A further includes a support device 125A and at least one magnetic attraction unit 124A, wherein the magnetic attraction unit 124A is disposed within the magnetic attraction surface 121A of the magnetic attraction device 12A. It is understood that the magnetic attraction surface 121A is formed at the location of the magnetic attraction unit 124A, and the non-magnetic attraction surface 122A of the magnetic attraction device 12A is formed at a location away from the magnetic attraction unit 124A. The support device 125A of the magnetic attraction device 12A is held in the mounting groove 1113A by the housing 111A.

[0083] The magnetic attraction device 12A further includes at least one support element 126A, wherein the support element 126A is disposed in the mounting groove 1113A of the housing 111A, and the support element 126A supports the carrier device 125A to maintain the relative position of the magnetic attraction device 12A. When the lamp 20 is charging in the wireless charging device 10A, the support element 126A supports the carrier device 125A at the outer opening of the mounting groove 1113A, and the lamp 20 is attracted by the magnetic attraction unit 124A of the magnetic attraction device 12A and attached to the surface of the charging body 10A. Preferably, the number of magnetic attraction units 124A in the magnetic attraction device 12A is at least two, wherein the magnetic attraction units 124A are spaced apart from each other, and the lamp 20 is attracted by the magnetic attraction units 124A spaced apart from each other, so that the lamp 20 being charged is aligned and attracted to the housing 111A of the charging body 11A.

[0084] It is worth mentioning that the supporting device 125A of the magnetic attraction device 12A protrudes outward from the mounting groove 1113A of the housing 111A. The user can adjust the position of the magnetic surface 121A and the non-magnetic surface 122A of the magnetic attraction device 12A relative to the mounting groove 1113A by pressing or pushing the supporting device 125A.

[0085] like Figure 5C As shown, pressing or pushing the support device 125A of the magnetic attraction device 12A, wherein the support device 125A of the magnetic attraction device 12A is pressed to the inner side of the mounting groove 1113A, wherein the magnetic surface 121A and the lamp 20 are misaligned, thereby reducing the attraction of the magnetic attraction device 12A to the lamp housing 20, so as to separate the lamp 20 from the charging body 11A. Preferably, the support element 126A is implemented as a spring element, wherein the spring element is disposed inside the mounting groove 1113A, and the support element 126A pushes the support device 125A of the magnetic attraction device 12A.

[0086] It is understood that, in this preferred embodiment of the present invention, the magnetic attraction device 12A is disposed on the charging body 11A in a parallel-moving manner. Those skilled in the art will appreciate that the magnetic attraction device 12A can also be implemented as a dial device.

[0087] Referring to the accompanying drawings of this invention Figure 6 and Figure 7As shown, another optional embodiment of the wireless charging device 10 of the wireless charging lighting system according to the preferred embodiment of the present invention will be described below. The wireless charging device 10 includes a charging body 11, a magnetic attraction device 12, at least one mounting unit 13, and at least one prompting device 14. The magnetic attraction device 12 is movably disposed on the charging body 11. By adjusting the position of the magnetic attraction device 12, the lamp 20 is attracted to the upper surface of the charging body 11 by the magnetic attraction device 12, and the lamp 20 is easily separated from the charging body 11. It is worth noting that in this preferred embodiment of the present invention, the structure and shape of the charging body 11, the mounting unit 13, and the prompting device 14 are the same as in the first preferred embodiment, except for the magnetic attraction device 12. The charging body 11 includes a housing 111, at least one transmitting module 112, a power interface 113, and a circuit board 114. The transmitting module 112 is electrically connected to an external power source through the power interface 113. The housing 111 further includes an upper housing 1111 and a lower housing 1112, wherein the upper housing 111 forms a mounting groove 1113, and wherein the magnetic suction device 12 is movably disposed in the mounting groove 1113.

[0088] In detail, the magnetic attraction device 12 is pivotally mounted on the charging body 11, wherein the charging body 11 supports the magnetic attraction device 12 to swing up and down along a rotation axis. The magnetic attraction device 12 includes a rotation axis 123, a support device 125, and at least one magnetic attraction unit 124, wherein the rotation axis 123 is rotatably connected to the upper housing 1111 of the housing 111. The magnetic attraction unit 124 is embedded in the support device 125, and the support device 125 carries the magnetic attraction unit 124 to rotate about the rotation axis 123. When the support device 125 rotates to its highest position, the upper surfaces of the support device 125 and the magnetic attraction unit 124 are parallel to the charging body 11. By rotating the support device 125 downwards based on the rotation axis 123, the magnetic attraction unit 124 is moved downwards by the support device 125, so that the magnetic attraction unit 124 is away from the upper surface of the charging body 11.

[0089] Preferably, in this invention, the number of magnetic units 124 in the magnetic attraction device 12 is at least two, wherein the magnetic units 124 are arranged at intervals. By the magnetic attraction of the at least two magnetic units 124 at different positions to the lamp 20, the relative position of the lamp 20 and the wireless charging device 10 is adjusted, which facilitates the accurate alignment of the lamp 20 and the wireless charging device 10, thereby improving the charging efficiency of the wireless charging device 10 for the lamp 20.

[0090] Therefore, when the lamp 20 is placed above the charging body 11, the magnetic unit 124 of the magnetic attraction device 12 attracts the lamp 20, causing the lamp 20 to adhere to the upper housing 1111 of the housing 111. When the lamp 20 is separated from the wireless charging device 10, pressing the distal end of the support device 125 causes the support device 125 to rotate around the rotation axis 123 carrying the magnetic unit 124, wherein the magnetic unit 124 is rotated away from the lamp 20, thereby reducing the magnetic force attracting the lamp 20.

[0091] like Figure 7 As shown, the magnetic attraction device 12 further includes at least one support element 126, wherein the support element 126 is disposed below the carrier device 125, providing an upward supporting force to the carrier device 125, so that the carrier device 125 supports the magnetic attraction unit 124 in a position close to the upper surface of the charging body 11. Preferably, the support element 126 is implemented as a spring element.

[0092] like Figures 8 to 9C As shown, the lamp 20 of the wireless charging lighting system includes a lamp body 21 and at least one magnetic metal unit 22, wherein the magnetic metal unit 22 is disposed on the lamp body 21. It is understood that the magnetic metal unit 22 can be attracted by the magnetic unit 124 of the magnetic charging device 12, so that the wireless charging device 10 can be attracted to the lamp body 21 via the magnetic metal unit 22. Preferably, the magnetic metal unit 22 is embedded in the lamp body 21 of the lamp 20 to reduce the distance between the transmitting module 112 of the wireless charging device 10 and the lamp body 21. More preferably, the magnetic metal unit 22 can be attracted by the magnetic unit 124, but the magnetic metal unit 22 itself is not magnetic, to prevent the magnetic metal unit 22 from becoming magnetic after the lamp 20 is charged and attracting impurities such as iron filings, thereby affecting the next charging of the lamp 20. The magnetic metal object 22 can be, but is not limited to, an iron block, an iron alloy block, or other materials that can be attracted by the magnetic unit 124.

[0093] Preferably, in this preferred embodiment of the invention, the number of magnetic metal units 22 is the same as the number of magnetic units 124 of the wireless charging device 10, that is, the number of magnetic metal units 22 of the lamp 20 is at least two, and the magnetic metal units 22 are arranged at intervals. Preferably, the interval distance between the magnetic metal units 22 is the same as the interval distance between the magnetic units 124, which is H. When the lamp 20 is placed on the wireless charging device 10, the magnetic metal units 22 are correspondingly attracted to the magnetic units 124 of the wireless charging device 10, wherein the magnetic units 124 and the magnetic metal units 22 are vertically aligned, so that the magnetic unit 12 of the wireless charging device 10 is attracted to the top of the charging body 11 through the magnetic metal units 22 of the lamp 20.

[0094] The lamp body 21 includes at least one light source 211, a lamp housing 212, at least one receiving module 213, and at least one energy storage device 214. The light source 211 is disposed in the lamp housing 212 and electrically connected to the energy storage device 214, which provides operating power to the light source 211. The receiving module 213 is disposed in the lamp housing 212. When the lamp 20 is placed on the wireless charging device 10, the receiving module 213 receives the electromagnetic signal emitted by the transmitting module 112 and generates an induced current. The receiving module 213 is electrically connected to the energy storage device 214, and the electrical energy generated by the receiving module 213 is stored in the energy storage device 214.

[0095] It is worth mentioning that, in this preferred embodiment of the present invention, the light source 211 may be, but is not limited to, an LED lamp, and the type and structure of the light source 211 are merely exemplary and not limiting.

[0096] The lamp housing 212 includes an upper lamp housing 2121, a lower lamp housing 2122, and a lamp body space 2123 further formed by the upper lamp housing 2121 and the lower lamp housing 2122, wherein the receiving module 213 and the energy storage device 214 are held in the lamp body space 2123 by the lamp housing 212. The upper lamp housing 2121 and the lower lamp housing 2122 are hermetically connected.

[0097] The receiving module 213 is attached to the inner side of the lower housing 2122 of the lamp housing 212, so that when the wireless charging device 10 wirelessly charges the lamp 20, the distance between the receiving module 212 and the transmitting module 122 is reduced, thereby improving the charging efficiency of the wireless charging device 10 for the lamp 20. Preferably, the position of the receiving module 213 relative to the magnetic metal unit 22 corresponds to the relative position of the transmitting module 122 relative to the magnetic unit 124, that is, when the magnetic unit 124 is aligned with the magnetic metal unit 22, the transmitting module 122 is aligned with the receiving module 213. Therefore, the alignment of the transmitting module 122 and the receiving module 213 can be determined by the relative position of the magnetic unit 124 and the magnetic metal unit 22.

[0098] When the lamp 20 is placed above the wireless charging device 10 for charging, each of the magnetic units 124 of the wireless charging device 10 attracts each of the magnetic metal units 22 of the lamp 20, so that each of the magnetic units 124 of the wireless charging device 10 is aligned with each of the magnetic metal units 22 of the lamp 20, thereby aligning the transmitting module 122 with the receiving module 213. In other words, along the charging direction of the wireless charging device 10, the wireless charging device 10 attracts the lamp 20 through magnetic attraction, so that the transmitting module 122 is aligned with the receiving module 213, thereby improving the charging efficiency of the lamp 20.

[0099] It is worth mentioning that the distance between the transmitting module 122 and the receiving module 213 is greater than or equal to 2mm.

[0100] It is worth mentioning that the energy storage device 214 is implemented as a battery cell or battery pack with charging and discharging functions, wherein the energy storage device 214 stores the induced electrical energy generated by the receiving module 213 to provide light for the light source 211.

[0101] The light source 211 includes at least one light-emitting unit 2111 and a light source bracket 2112, wherein the light source bracket 2112 fixes the light-emitting unit 2111 to the housing 212. Preferably, the light-emitting unit 2111 is thermally connected to the light source bracket 2112, so that the light source bracket 2112 dissipates the heat generated by the light-emitting unit 2111 during light emission by means of heat transfer, thereby reducing the temperature of the light-emitting unit 2111. It is worth mentioning that, in this invention, the specific structure and shape of the lamp 20 are merely exemplary and not limiting.

[0102] The lamp 20 further includes a bracket 23, wherein the bracket 23 is disposed on the lamp body 21, and wherein the bracket 23 supports the illumination of the lamp body 21. Preferably, the bracket 23 is movably connected to the outside of the lamp body 21, and the angle at which the lamp body 21 is placed and supported is adjusted by adjusting the rotation angle of the bracket 23.

[0103] like Figures 10A to 10C The invention illustrates the usage and application scenarios of the wireless charging lighting system. The wireless charging device 10 can be fixedly installed at any angle on a wall, desktop, or workbench (flat or inclined surface); or the wireless charging device 10 can be adsorbed onto a ferrous metal surface. Figure 9B As shown, when the lamp 20 is placed on the wireless charging device 10 for charging, the magnetic attraction device 12 of the wireless charging device 10 is adjusted so that the magnetic surface 121 of the magnetic attraction device 12 faces the charging direction of the wireless charging device 10 or faces the lamp 20. After the magnetic attraction device 12 is adjusted, it is locked by the rotating latch 126 to maintain its position and prevent it from rotating and separating from the lamp 20 during charging.

[0104] The magnetic metal unit 22 of the lamp 20 is attracted to the magnetic unit 124 of the wireless charging device 10, wherein the magnetic metal unit 22 and the magnetic unit 124 are vertically aligned. Since the position of the transmitting module 112 relative to the magnetic unit 124 and the position of the receiving module 213 relative to the magnetic unit 22 are the same, when the magnetic metal unit 22 and the magnetic unit 124 are aligned, the transmitting module 12 and the receiving module 213 are vertically aligned so that the transmitting module 12 transmits an electromagnetic signal carrying electrical energy to the receiving module 213, so that the receiving module 213 can generate induced electrical energy based on the electromagnetic signal transmitted by the transmitting module 12.

[0105] When the lamp 20 is separated from the wireless charging device 10, for example, when the lamp 20 is fully charged, the magnetic attraction device 12 can be rotated or turned so that the non-magnetic surface 122 of the magnetic attraction device 12 faces the lamp 20. Since the non-magnetic surface 122 is not magnetic or has a weak magnetic attraction, the attraction force generated by the lamp 20 is small, thus facilitating the separation of the lamp 20 and the wireless charging device 10.

[0106] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved.
