[0036] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0037] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

The association relationship of the associated objects is described, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0040] Please refer to Figure 1-Figure 7 The present application provides a mobile device light supplement 100, which is used in cooperation with a mobile device (not shown in the figure) to supplement light for a shooting object when a user uses the mobile device to shoot; wherein the mobile device can include a mobile terminal and a mobile power supply, wherein the mobile terminal can include a mobile phone, a tablet computer and the like, and the mobile power supply can include a power bank, and the present embodiment does not limit this.

[0041] In the present application, the mobile device light supplement 100 includes a shell 10, a first lamp group 20, a second lamp group 30 and a circuit assembly 40.

[0042] The shell 10 can be made of plastic material, so that it has the advantages of light weight and low manufacturing cost; the shape of the shell 10 can be a regular shape such as a circle or a square, so that the shape of the shell 10 is relatively regular, so as to facilitate the manufacture and production of the shell 10, and the present embodiment does not limit the material and shape of the shell 10. The inside of the shell 10 is formed with a receiving cavity 10A, and the side wall of the shell 10 is provided with a through opening communicating with the receiving cavity 10A.

[0043] The first light group 20 and the second light group 30 both include LED lamp beads. This embodiment does not limit the specific types of the first light group 20 and the second light group 30. Specifically, the first light group 20 and the second light group 30 both include multiple LED lamp beads, which are arranged at intervals and work together to emit light. The first light group 20 and the second light group 30 are arranged at intervals in the accommodating cavity 10A, and the light emission directions of the two are arranged in opposite directions. For example, when the user needs to shoot an object located far away, the first light group 20 can be turned on so that the light emitted by the first light group 20 is directed toward the shooting object located far away to achieve the desired fill light effect. When the user needs to take a selfie, the second light group 30 can be turned on so that the light emitted by the second light group 30 is directed toward the user himself to achieve the desired fill light effect.

[0044] In one exemplary embodiment, the multiple LED lamp beads of the first lamp group 20 include one or a combination of warm white lamp beads, cool white lamp beads, and colored lamp beads. The first lamp group 20 may be cool white lamp beads, which provides a stable color temperature and low cost. The first lamp group 20 may be a combination of cool white lamp beads and warm white lamp beads, which allows the first lamp group 20 to adjust between warm and cool light (for example, 2700K and 6500K) to meet different fill lighting needs of users. The first lamp group 20 may be a combination of cool white lamp beads, warm white lamp beads, and colored lamp groups to meet various fill lighting needs of users.

[0045] In another exemplary embodiment, the multiple LED lamp beads of the second lamp group 30 include one or a combination of warm white lamp beads, cool white lamp beads, and colored lamp beads. The second lamp group 30 can be cool white lamp beads, which has a stable color temperature and low cost. The second lamp group 30 can be a combination of cool white lamp beads and warm white lamp beads, which can adjust the second lamp group 30 between warm light and cool light (for example, 2700K and 6500K) to meet the different fill lighting needs of users. The second lamp group 30 can be a combination of cool white lamp beads, warm white lamp beads, and colored lamp groups to meet the various fill lighting needs of users.

[0046] The circuit assembly 40 includes a circuit board 41 and an electrical connector 42. The circuit board 41 is disposed within the housing cavity 10A and is electrically connected to the first and second light groups 20 and 30. It will be appreciated that the circuit board 41 can control the lighting and extinguishing of the first and second light groups 20 and 30, as well as control lighting parameters such as brightness and color temperature of the first and second light groups 20 and 30, although this embodiment does not limit this.

[0047] The electrical connector 42 may be a Type-C connector, so that it can mate with a Type-C port on a mobile device. This embodiment does not impose any specific restrictions on the type of the electrical connector 42; the electrical connector 42 may also be a USB-A connector or other type of connector. The electrical connector 42 is electrically connected to the circuit board 41 and is configured to mate with the port on the mobile device, enabling the mobile device to power the first and second light groups 20 and 30 via the circuit board 41. It is understood that the electrical connector 42 is connected to the housing 10 and is partially exposed outside the accommodating cavity 10A by being inserted through the opening.

[0048] In some usage scenarios, when the mobile device is a mobile phone, the user can use the mobile phone to take pictures while the mobile phone can be used to power the mobile device fill light 100, so that the mobile device fill light 100 can provide fill light for the subject.

[0049] On the basis that the mobile device can be electrically connected to the circuit board 41 through the electrical connection connector 42, and can then provide power to the first light group 20 and the second light group 30 through the circuit board 41, the user can directly power the mobile device fill light 100 through the mobile device. In this way, compared with the existing mobile device fill light with a built-in battery, the present application can use the power of the mobile device to continuously power the mobile device fill light 100, so as to ensure that the use time of the mobile device fill light 100 can be greatly extended, effectively overcoming the problem that the mobile device fill light 100 has insufficient battery life and cannot provide fill light for a long time during shooting. At the same time, on the basis of eliminating the built-in battery, the size of the mobile device fill light 100 can also be reduced, making it easier for users to carry.

[0050] When one of the first light group 20 and the second light group 30 is on, the other is off. In this way, this embodiment can avoid the first light group 20 and the second light group 30 from working at the same time. This arrangement can, on the one hand, reduce the power consumption of the mobile device fill light 100, thereby reducing the power supply pressure of the mobile device. On the other hand, it can prevent the first light group 20 and the second light group 30 from working at the same time, which may cause excessive heat in the mobile device fill light 100, thereby effectively reducing the heat dissipation requirements of the mobile device fill light 100.

[0051] The circuit board 41 comprises a first substrate 411, a second substrate 412 and a heat conduction structure 413. The first substrate 411 is configured to be electrically connected with the first lamp group 20 to control the operation of the first lamp group 20 and supply power to the first lamp group 20. The second substrate 412 is configured to be electrically connected with the second lamp group 30 to control the operation of the second lamp group 30 and supply power to the second lamp group 30. The heat conduction structure 413 is connected between the first substrate 411 and the second substrate 412 to establish a heat conduction path between the first substrate 411 and the second substrate 412. The heat conduction structure 413 can be in the form of a heat conduction plate 4131 or a heat conduction silica gel. In this embodiment, the specific form of the heat conduction structure 413 is not limited.

[0052] It can be understood that, when one of the first lamp group 20 and the second lamp group 30 is turned on and the other is turned off, if the first lamp group 20 is turned on, the heat generated by the first lamp group 20 and the first substrate 411 will be partially conducted to the heat conduction structure 413 and the second substrate 412 to increase the heat dissipation area of the circuit board 41, so that the heat can be quickly dissipated to the outside to overcome the problem of heat accumulation on the first substrate 411, thereby effectively improving the heat dissipation performance of the mobile device light supplement lamp 100. If the second lamp group 30 is turned on, the heat generated by the second lamp group 30 and the second substrate 412 will be partially conducted to the heat conduction structure 413 and the first substrate 411 to increase the heat dissipation area of the circuit board 41, so that the heat can be quickly dissipated to the outside to overcome the problem of heat accumulation on the second substrate 412, thereby effectively improving the heat dissipation performance of the mobile device light supplement lamp 100.

[0053] Please refer to Figure 3-Figure 7 In some embodiments, the heat conduction structure 413 is a heat conduction plate 4131, and the first substrate 411, the heat conduction plate 4131 and the second substrate 412 of the circuit board 41 are an integral structure. On the one hand, this can eliminate the gap between the first substrate 411 and the heat conduction plate 4131 and the gap between the second substrate 412 and the heat conduction plate 4131 to improve the heat conduction efficiency of the first substrate 411, the heat conduction plate 4131 and the second substrate 412. On the other hand, this can reduce the assembly steps of the circuit board 41 to reduce the assembly cost of the circuit board 41.

[0054] It can be understood that, based on the heat-conducting structure 413 being a heat-conducting plate 4131, the circuit board 41 can include six heat-dissipating surfaces. Specifically, the six heat-dissipating surfaces include two surfaces of the first substrate 411 opposite to each other along its thickness direction, two surfaces of the second substrate 412 opposite to each other along its thickness direction, and two surfaces of the heat-conducting plate 4131 along its thickness direction, thereby effectively increasing the heat-dissipating surface area of ​​the circuit board 41 to quickly dissipate heat to the outside.

[0055] Please refer to Figure 4-Figure 7 Furthermore, the first substrate 411, the second substrate 412, and the heat conducting plate 4131 can all be arranged in a square or circular shape, which is not limited in this embodiment. The first substrate 411 extends in parallel with the second substrate 412, and the heat conducting plate 4131 extends between the first substrate 411 and the second substrate 412.

[0056] Among them, the extension direction of the heat conducting plate 4131 is perpendicular to the extension direction of the first substrate 411, that is, perpendicular to the extension direction of the second substrate 412. In this way, the shape of the circuit board 41 is U-shaped, which is relatively regular and convenient for workshop manufacturing.

[0057] Please refer to Figure 4-Figure 7 In some embodiments, the first substrate 411, the heat conducting plate 4131 and the second substrate 412 are all aluminum substrates. The thermal conductivity of the aluminum substrate is relatively high, so that heat can be dissipated quickly, effectively reducing the light decay of the first lamp group 20 and the second lamp group 30. In addition, the material cost of the aluminum substrate is relatively low, which can reduce the overall manufacturing cost of the mobile device fill light 100. This embodiment does not impose specific restrictions on the materials of the first substrate 411, the second substrate 412 and the heat conducting plate 4131. In other embodiments, the first substrate 411, the heat conducting plate 4131 and the second substrate 412 can also be ceramic substrates.

[0058] Please refer to Figure 1-Figure 7 In some embodiments, the light of the first light group 20 that passes through the shell 10 and is emitted to the outside is configured as a focused light. It can be understood that the focused light can have a focusing effect, thereby effectively improving the illumination brightness. With this arrangement, when the user needs to shoot an object located far away, the first light group 20 can be lit so that the focused light is emitted to the object located far away to achieve the desired fill light effect.

[0059] The light of the second light group 30 that passes through the shell 10 and is emitted to the outside is configured as diffuse light. It can be understood that the diffuse light has a soft light effect, thereby reducing the hardness of the light. With this arrangement, when the user needs to take a selfie, the second light group 30 can be turned on, so that the diffuse light emitted by the second light group 30 is emitted towards the user himself, so as to achieve the required fill light effect.

[0060] Thus, in this embodiment, by adopting the first light group 20 capable of emitting focused light and the second light group 30 capable of emitting diffuse light, when the user needs to fill in the light for a distant subject, the first light group 20 can be controlled to emit light, and when the user needs to fill in the light for himself, the second light group 30 can be controlled to emit light. In this way, the fill light function of the mobile device fill light 100 can be diversified to meet the different fill light needs of users.

[0061] Please refer to Figures 1-4 In some embodiments, the housing 10 includes a housing body 11 and a focusing lens 12. The interior of the housing body 11 forms a receiving cavity 10A. The light of the second lamp group 30 that passes through the housing body 11 and is emitted to the outside is configured as diffuse light.

[0062] The focusing lens 12 is molded on the outer surface of the shell body 11. It can be understood that the focusing lens 12 and the shell body 11 are an integrated structure, which can reduce the assembly steps between the focusing lens 12 and the shell body 11 and eliminate the gap between the focusing lens 12 and the shell body 11, so that as much light as possible emitted by the first lamp group 20 passes through the focusing lens 12 and is emitted outward.

[0063] The condenser lens 12 is located on the light path of the first lamp group 20 and is used to convert the light emitted by the first lamp group 20 into a concentrated light. In this way, the condenser lens 12 can be set to convert the light emitted by the first lamp group 20 into a concentrated light, thereby achieving a focusing effect.

[0064] Optionally, the focusing lens 12 includes a convex lens, which is located in the light path of the first lamp group 20 and is used to convert the light emitted by the first lamp group 20 into concentrated light. The convex lens can be an aspherical convex lens to achieve a better focusing effect. This embodiment does not specifically limit the type of convex lens.

[0065] Of course, this embodiment is not limited thereto, and the focusing lens 12 may also be a collimating lens, which can adjust scattered light into parallel light to reduce light diffusion, thereby achieving a similar focusing effect.

[0066] Please refer to Figure 1-Figure 5 In some embodiments, at least a portion of the housing 10 wall facing the second light assembly 30 is milky white, so that the light emitted by the second light assembly 30 is converted into diffuse light after passing through the housing 10. This simplifies the structure, eliminating the need for a dedicated light softening structure to alter the properties of the light emitted by the second light assembly 30, and thus reducing the manufacturing and assembly costs of the mobile device fill light 100.

[0067] Please refer to Figure 1-Figure 7 In some embodiments, a first trigger switch 4111 is provided on the first substrate 411, a first exposure opening 10B is provided on the shell 10, and the mobile device fill light 100 further includes a first button 60, which is provided through the first exposure opening 10B to trigger the first trigger switch 4111.

[0068] In this way, the user can directly press the first button 60 to trigger the first trigger switch 4111, thereby adjusting the brightness, color temperature and other light parameters of the first light group 20, and also controlling the lighting or extinguishing of the first light group 20.

[0069] Please refer to Figure 1-Figure 7 In some embodiments, a second trigger switch 4121 is provided on the second substrate 412, the shell 10 is provided with a second exposure port 10C, and the mobile device fill light 100 further includes a second button 70, which is provided through the second exposure port 10C to trigger the second trigger switch 4121.

[0070] In this way, the user can directly press the second button 70 to trigger the second trigger switch 4121, thereby adjusting the brightness, color temperature and other light parameters of the second light group 30, and can also control the lighting or extinguishing of the second light group 30, which is convenient and quick to operate.

[0071] Please refer to Figure 1-Figure 7 In some embodiments, a first trigger switch 4111 is provided on the first substrate 411, a first exposed opening 10B is provided on the housing 10, and the mobile device fill light 100 further includes a first button 60, which is disposed through the first exposed opening 10B and is used to trigger the first trigger switch 4111. A second trigger switch 4121 is provided on the second substrate 412, a second exposed opening 10C is provided on the housing 10, and the mobile device fill light 100 further includes a second button 70, which is disposed through the second exposed opening 10C and is used to trigger the second trigger switch 4121.

[0072] In this way, the user can directly press the first button 60 to trigger the first trigger switch 4111, thereby adjusting the brightness, color temperature and other parameters of the first light group 20, and also controlling the lighting or extinguishing of the first light group 20; and the user can directly press the second button 70 to trigger the second trigger switch 4121, thereby adjusting the brightness, color temperature and other light parameters of the second light group 30, and also controlling the lighting or extinguishing of the second light group 30, which is convenient and quick to operate.
