[0039] As Figure 1-2 shown, in an embodiment of the utility model, a supplementary light includes a lighting component 10 and a power supply base 20. The lighting component 10 includes a lamp board 11 and a wireless receiving induction coil 13 provided on the lamp board 11. Lamp beads 12 are provided on the lamp board 11. The power supply base 20 is correspondingly arranged with the lighting component 10. A wireless transmitting coil 21 corresponding to the wireless receiving induction coil 13 is provided on the power supply base 20. After the power supply base 20 is powered on, electric energy is wirelessly transmitted to the wireless receiving induction coil 13 through the wireless transmitting coil 21. The wireless receiving induction coil 13 is used to receive electric energy to supply power to the lamp board 11, and the lamp beads 12 on the lamp board 11 can emit light for supplementary lighting.
[0040] In the above embodiment, the power supply base 20 is correspondingly arranged with the lighting component 10. The traditional power cord power supply method between the power supply base 20 and the lighting component 10 is replaced by the above wireless power supply device between the power supply base 20 and the lighting component 10. There is no physically connected power cord between the power supply base 20 and the lighting component 10 to limit the movement flexibility of the lighting component 10. When the power supply base 20 is powered on, the wireless transmitting coil 21 generates an alternating magnetic field. The wireless receiving induction coil 13 corresponding to the wireless transmitting coil 21 senses the magnetic field change and generates an induced current. The induced current is converted into direct current through a rectifying circuit. The direct current can continuously supply power for the lamp beads 12 on the lamp board 11 to emit light, avoiding the delay of the work progress caused by the need to spend a lot of time charging after the battery in the existing supplementary light is exhausted, and improving the work efficiency. In addition, after the power supply base 20 is fixed in position, the lighting component 10 can freely move relative to the power supply base 20 without being restricted by the power cord. As long as the distance between the lighting component 10 and the power supply base 20 does not exceed the distance at which the wireless receiving induction coil 13 of the lighting component 10 can sense the magnetic field change when the lighting component 10 moves.
[0041] In an embodiment of the utility model, the power supply base 20 can be powered in various ways. For example, the power supply base 20 is provided with an internal battery, and the internal battery directly supplies electrical energy to the power supply base 20. The power supply base 20 is connected to an external power supply in a wired manner such as a data cable, and the external power supply supplies electrical energy to the power supply base (20). The power supply base (20) obtains electrical energy through an external power supply in a wireless manner such as electromagnetic induction. Specifically, it can be set according to the actual needs of users, and is not limited here.
[0042] As Figure 1-2 shown, in an embodiment of the utility model, the lighting assembly 10 further includes a lamp frame 14. An inner cavity for accommodating the lamp board 11 is provided inside the lamp frame 14, and an installation cavity for accommodating the wireless receiving induction coil 13 is provided on the inner wall of the lamp frame 14. Integrating the wireless receiving induction coil 13 on the inner wall of the lamp frame 14 can make the entire lighting assembly 10 more compact and integrated. By providing an installation cavity on the inner wall of the lamp frame 14, the space inside the lamp frame 14 can be utilized more effectively, leaving more space for other components. Installing the wireless receiving induction coil 13 on the inner wall of the lamp frame 14 can provide a certain degree of physical protection for the wireless receiving induction coil 13, reducing damage caused by external impact or wear. The wireless receiving induction coil 13 can be hidden, making the appearance of the lighting assembly 10 cleaner and more beautiful. Installing the wireless receiving induction coil 13 on the inner wall of the lamp frame 14 helps to disperse the heat generated by the wireless receiving induction coil 13 to a larger surface area, thereby reducing the risk of local overheating.
[0043] As Figure 1-2 shown, in an embodiment of the utility model, the lighting assembly 10 further includes a rechargeable battery 15. After the wireless receiving induction coil 13 receives electrical energy, it can charge the rechargeable battery 15, and the rechargeable battery 15 is used to supply power to the lamp board 11. This fill light contains a rechargeable battery 15. The current generated by the receiving induction coil is stored in the battery, continuously charging the battery, and then the battery stores energy while continuously supplying power to the lamp board 11, avoiding delays in the work progress caused by the need to spend a large amount of time charging after the battery is exhausted, and improving work efficiency.
[0044] As Figure 1-2 shown, in an embodiment of the utility model, a placement cavity for placing the rechargeable battery 15 is further provided on the inner wall of the lamp frame 14. Placing the battery on the inner wall of the lamp frame 14 can make the entire lamp more compact and reduce the occupied space. The battery may generate heat during operation, and placing it on the inner wall of the inner cavity helps to dissipate heat and avoid local overheating. Placing the battery on the inner wall of the inner cavity can reduce damage to the battery caused by external factors such as dropping and impact. Hiding the battery inside the lamp frame 14 can make the appearance of the lamp cleaner and more beautiful.
[0045] In an embodiment of the utility model, the lighting assembly (10) is magnetically connected to the power supply base (20). Optionally, magnets are provided on both the lighting assembly (10) and the power supply base (20), and the lighting assembly (10) and the power supply base (20) are magnetically connected through the magnets. Alternatively, one of the lighting assembly (10) and the power supply base (20) is provided with a metal part, and the other is provided with a magnetic part that can magnetically attract the metal part. The magnetic connection between the lighting assembly (10) and the power supply base (20) is achieved by means of the magnetic attraction between the metal part and the magnetic part. Of course, the specific implementation structure of the magnetic connection can be set according to the actual needs of the user, which is not limited here. The magnetic connection between the lighting assembly (10) and the power supply base (20) can quickly achieve automatic alignment of the relative positions and stable connection.
[0046] As Figure 1-2 shown, in an embodiment of the utility model, a plurality of LED lamp beads 12 arranged in an array are provided on the lamp board 11. The LED lamp beads 12 arranged in an array can more effectively concentrate the light, improve the light efficiency, make the light more concentrated and uniform, and by controlling the LED lamp beads 12 of different colors, the color can be adjusted to meet the fill light requirements of different scenarios.
[0047] As Figure 1-2 shown, in an embodiment of the utility model, the wireless receiving induction coil 13 is arranged around the outer periphery of the lamp board 11. Arranging the wireless receiving induction coil 13 on the outer periphery of the lamp board 11 can make more effective use of the space, because it will not occupy the central area of the lamp board 11, and the central area can be used to place the lamp beads 12 or other important components. The central area of the lamp board 11 may generate more heat due to the light emission of the lamp beads 12. Placing the receiving induction coil on the outer periphery of the lamp board 11 helps to disperse the heat, and placing the coil on the outer periphery can reduce the electromagnetic interference to the lamp beads 12 or other sensitive electronic components, because the magnetic field generated by the coil may have an impact on some electronic components.
[0048] As Figure 1-2 shown, in an embodiment of the utility model, lamp beads 12 are provided on the lamp board 11, and the lighting assembly 10 further includes a protection board 16 covering above the lamp frame 14, and the protection board 16 covers above the lamp beads 12 of the lamp board 11. The protection board 16 can physically protect the lamp beads 12 from external impacts, dust, moisture and other potential damages, and extend the service life of the lamp beads 12. The protection board 16 can prevent dust and moisture from entering the area of the lamp board 11, which is particularly important for fill light lamps used outdoors or in humid environments. The protection board 16 can prevent users from directly contacting the lamp beads 12 and reduce the risk of electric shock, especially when the lamp beads 12 may generate high temperatures during operation. The protection board 16 can reduce the direct reflection and scattering of light, reduce glare, and provide a more comfortable lighting environment. AsFigure 1-2 As shown, in an embodiment of the utility model, the protection plate 16 is made of a transparent material. The protection plate 16 of the fill light is made of a transparent material. Such a design is to ensure that light can effectively penetrate and illuminate the target area. The selection of the transparent material has an important impact on the performance of the fill light because they need to have good light transmittance, sufficient strength, and weather resistance. In fill lights, common transparent materials include polycarbonate (PC), polymethyl methacrylate (PMMA, commonly known as acrylic or plexiglass), glass, and various plastic materials.
[0049] As Figure 1-2 shown, in an embodiment of the utility model, the power supply base 20 is in a disc shape, and the wireless transmitting coil 21 is wound on one side of the power supply base 20 close to the lighting assembly 10. The wound wireless transmitting coil 21 can generate a relatively uniform magnetic field, establish an effective electromagnetic field between the wireless transmitting coil 21 and the wireless receiving induction coil 13 to transmit energy. The wound wireless transmitting coil helps to improve the efficiency of energy transmission. When the transmitting coil is tightly wound, the intensity and consistency of the magnetic field increase, thereby improving the energy coupling efficiency. It can also maximize the surface area of the coil, thereby increasing the intensity of the magnetic field. The symmetry of the circular coil helps to reduce the non-uniformity of the magnetic field, which is beneficial for ensuring that the receiving device can receive energy at any position on the charging base.
[0050] As Figure 1-2 shown, in an embodiment of the utility model, a controller 22 is further provided on the power supply base 20. The lighting assembly 10 includes a light sensor for sensing the ambient light intensity, and the controller 22 is used to adjust the light emission intensity of the lamp panel 11 according to the ambient light intensity. The light sensor can monitor the ambient light intensity in real time. The controller 22 adjusts the light emission intensity of the lamp panel 11 according to the monitored data to ensure an appropriate fill light effect under different lighting conditions and improve the fill light efficiency. When the ambient light is already sufficient, the controller 22 can reduce or turn off the light emission intensity of the lamp panel 11, thereby reducing energy consumption and achieving energy conservation and emission reduction. It can realize the automatic control of the fill light without manual intervention, improve the convenience of use, and at the same time reduce the uneven fill light or energy waste caused by human factors. By intelligently adjusting the light emission intensity, it is possible to avoid the lamp panel 11 working at the maximum brightness for a long time, reduce heat generation, and thus extend the service life of the lamp panel 11 and the entire fill light system. The controller 22 automatically adjusts the power output of the transmitter according to the usage requirements and battery status of the fill light to ensure efficient and stable energy transmission. At the same time, the controller 22 can also adjust the brightness and working mode of the LED light source according to the ambient light intensity or user settings.
[0051] In the supplementary light of the embodiment of the present utility model, after the power supply base 20 is powered on, it wirelessly transmits electric energy to the wireless receiving induction coil 13 through the wireless transmitting coil 21. The wireless receiving induction coil 13 receives the electric energy to supply power to the lamp board 11, and the lamp beads 12 on the lamp board 11 of the lighting assembly 10 can emit light for supplementary lighting. Therefore, the supplementary light can have the following usage scenarios:
[0052] 1). When the size and shape of the power supply base 20 are adapted to a tabletop (such as a desk), the charging base 20 is placed on or under the tabletop, and one or more lighting assemblies 10 within the magnetic induction range above and below the tabletop can be moved freely to provide lighting or supplementary lighting according to user needs;
[0053] 2). When the size and shape of the power supply base 20 are adapted to the floor of a room (such as a live broadcast room), the magnetic field within the room range can be enhanced by controlling the current size of the power supply base 20. At this time, the lighting assemblies 10 throughout the room can move freely in the room to emit light;
[0054] 3). When the size and shape of the power supply base 20 are adapted to the wall of an art gallery or museum, the magnetic field within the room range of the art gallery or museum can be enhanced by controlling the current size of the power supply base 20. At this time, the lighting assemblies 10 throughout the room can move freely in the room to emit light. The art gallery or museum can provide the best lighting effect for each work of art by precisely controlling the position and angle of the lighting assemblies 10. According to the change of the exhibition theme, the lighting layout can be easily adjusted to meet different exhibition needs.
[0055] 4). When the size and shape of the power supply base 20 are adapted to the floor of a hospital ward or treatment room, the magnetic field within the room range of the hospital ward or treatment room can be enhanced by controlling the current size of the power supply base 20. At this time, the lighting assemblies 10 throughout the room can move freely in the room to emit light. According to the needs of patients and the treatment process, the position and brightness of the lighting assemblies can be adjusted to provide a comfortable lighting environment. In the operating room, the lighting assemblies 10 can be precisely controlled to ensure the lighting and supplementary lighting requirements of the surgical area.
[0056] 5) During outdoor activities such as camping or picnicking, when the size and shape of the power supply base 20 are adapted to a floor mat, the lighting assembly 10 can be arranged on the ground to provide mobile lighting. At an outdoor stage or concert, the position of the lighting assembly 10 can be flexibly adjusted according to the stage layout and the audience area to create a dynamic lighting effect.
[0057] In summary, the embodiment of the present utility model has at least the following technical effects:
[0058] 1. There is no need for electrical connection between the power supply base and the lighting component through a power cord. After the power supply base is fixed in position, it obtains power from an external power source and wirelessly transmits electrical energy to the wireless receiving induction coil of the lighting component through a wireless transmitting coil provided by itself. After the wireless receiving induction coil receives the electrical energy, it supplies power to the lamp board of the lighting component, and the lamp beads on the lamp board can emit light for supplementary lighting. In the embodiment of the present invention, a wireless power supply device is used between the power supply base and the lighting component to replace the traditional power cord power supply method between the power supply base and the lighting component. The lighting component can move freely relative to the power supply base without being restricted by the power cord, enabling the lighting component in the supplementary light to easily move to any place where supplementary lighting is required, especially suitable for occasions where the lighting position needs to be frequently adjusted, such as photography studios, exhibition layouts, stage performances, etc. It gets rid of the bondage of the traditional power cord and is suitable for various display and lighting occasions;
[0059] 2. Since there is no need for physical connection of the power cord between the power supply base and the lighting component, the installation process of the lighting component is simpler and faster, and it is also more convenient to maintain and replace the lighting component, reducing the long-term use and maintenance costs. The wireless power supply between the power supply base and the lighting component also avoids the safety hazards brought by the power cord and can reduce complex cable management work, improving work efficiency;
[0060] 3. When the power supply base, which acts as a wireless charging transmitter, is connected to the power supply, an alternating magnetic field is generated. The ring-shaped receiving coil in the fully transparent supplementary light senses the magnetic field change and generates an induced current. The induced current is converted into direct current through a rectifying circuit and stabilized by a voltage stabilizing circuit, and then managed by a charging control circuit. If the lighting component contains a battery, the battery is continuously charged, and the battery continuously supplies power to the LED light source; if there is no battery, it directly supplies power to the LED light source continuously, avoiding the delay of the work progress caused by the need to spend time charging after the battery in the existing supplementary light is depleted, and improving work efficiency;
[0061] 4. The power supply base is also provided with a controller. The controller can automatically adjust the power output of the transmitter according to the usage requirements of the supplementary light and the battery status to ensure efficient and stable energy transmission. At the same time, the controller can also adjust the brightness and working mode of the LED light source according to the ambient light intensity or user settings, automatically adjusting charging and lighting, improving energy efficiency and usage convenience.
[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
