[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0041] Please refer to Figure 1-Figure 5 The present application proposes a mobile device fill light 100, which is used in conjunction with a mobile device (not shown in the figure) to provide fill light for the subject when the user uses the mobile device to take pictures; wherein the mobile device may include a mobile terminal and a mobile power supply, wherein the mobile terminal may include a mobile phone, a tablet computer, etc., and the mobile power supply may include a power bank, which is not limited in this embodiment.

[0042] In the embodiment of the present application, the mobile device fill light 100 includes a housing 10 , a first light group 20 , a second light group 30 and a circuit assembly 40 .

[0043] The housing 10 can be made of plastic, which makes it lightweight and has the advantages of low manufacturing cost. The housing 10 can be shaped in a relatively regular shape, such as a circle or a square, to make the shape of the housing 10 more regular and facilitate its manufacture and production. This embodiment does not limit the material and shape of the housing 10. The housing 10 has an internal accommodating cavity 10A formed therein, and a sidewall of the housing 10 has an opening that communicates with the accommodating cavity 10A.

[0044] The first and second lamp groups 20 and 30 both include LED lamp beads. This embodiment does not limit the specific types of the first and second lamp groups 20 and 30. Each of the first and second lamp groups 20 and 30 includes multiple LED lamp beads, which are spaced apart and work together to emit light. The first and second lamp groups 20 and 30 are spaced apart within the accommodating cavity 10A, and their light emission directions are opposite.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In this way, the mobile device can be electrically connected to the circuit board 41 via the electrical connection connector 42, and can then provide power to the first light group 20 and the second light group 30 via the circuit board 41. In some usage scenarios, when the mobile device is a mobile phone, the user can use the mobile phone to power the mobile device fill light 100 while taking a photo, so that the mobile device fill light 100 can provide fill light for the subject.

[0050] Among them, the light of the first light group 20 that passes through the shell 10 and is emitted to the outside is configured as a focusing light. It can be understood that the focusing light has a focusing effect and can improve 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 focusing light emitted by the first light group 20 is emitted to the shooting object located far away, so as to achieve the required fill light effect.

[0051] 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.

[0052] The technical solution of the present application adopts the first light group 20 to emit concentrated light, and the second light group 30 to emit diffuse light, so that 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.

[0053] In addition, the present application uses the electrical connection connector 42 to be plugged into the interface of an external mobile device, so that 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.

[0054] Please refer to Figure 1-Figure 5 In some embodiments, the mobile device fill light 100 has a first working state and a second working state. The user can control the actual fill light demand and control the mobile device fill light 100 to be in the first working state or the second working state. Specifically, when the user needs to provide spotlight light to a distant subject, the mobile device fill light 100 can be switched to the first working state, and when the user needs to take a selfie of himself, the mobile device fill light 100 can be switched to the second working state.

[0055] When the mobile device fill light 100 is in the first working state, the circuit board 41 controls the first light group 20 to light up and controls the second light group 30 to turn off. When the mobile device fill light 100 is in the second working state, the circuit board 41 controls the second light group 30 to light up and controls the first light group 20 to turn off.

[0056] In this way, only one of the first light group 20 and the second light group 30 of the mobile device fill light 100 of this embodiment will work, and the first light group 20 and the second light group 30 will not work 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.

[0057] Please refer to Figures 1-4 In some embodiments, the housing 10 includes a housing body 11 and a focusing lens 12. The housing body 11 defines a receiving cavity 10A. Light from the second lamp assembly 30 that passes through the housing body 11 and is emitted to the outside is configured as diffuse light. The focusing lens 12 is disposed on the outer surface of the housing body 11. It is understood that light from the first lamp assembly 20, after passing through the housing body 11, is emitted toward the focusing lens 12.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Please refer to Figures 1-4 Furthermore, the focusing lens 12 and the shell body 10 are an integrated structure. 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 can 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.

[0062] It can be understood that if the distance between the condenser lens 12 and the light-emitting surface of the first lamp group 20 is too large, part of the light emitted by the first lamp group 20 will not be emitted to the outside through the condenser lens 12. Based on this, in some embodiments, the outer surface of the shell body 11 has a sunken area 11A, which is recessed towards the first lamp group 20.

[0063] The condenser lens 12 is arranged in the sunken area 11A. In this way, the distance between the condenser lens 12 and the first lamp group 20 can be shortened by the recessed arrangement of the sunken area 11A, so that as much light as possible emitted by the first lamp group 20 can be emitted to the outside through the condenser lens 12. Moreover, the recessed arrangement of the sunken area 11A can also reduce the overall size of the mobile device light supplement lamp 100, thereby facilitating the user to carry it and effectively improving the user's experience.

[0064] Please refer to Figure 1-Figure 5 In some embodiments, the inner surface of the shell body 11 is provided with a compound eye structure 111, which is located on the light-emitting path of the first lamp group 20. It can be understood that the compound eye structure 111 is a honeycomb structure, so that when the light emitted by the first lamp group 20 passes through the compound eye structure 111, it can achieve uniform light mixing, thereby effectively improving the light supplement effect of the light emitted by the first lamp group 20.

[0065] Please refer to Figure 1-Figure 5 In some embodiments, at least part of the shell wall of the shell body 11 towards the second lamp group 30 is provided in a milky white color, so that the light emitted by the second lamp group 30 can be converted into diffuse light after passing through the shell body 11.

[0066] In this way, the light of the second lamp group 30 will be converted into diffuse light after passing through the shell wall of the shell body 10 which is milky white, which is simple in structure and does not need to set up a special soft light structure to change the light property of the second lamp group 30, thereby reducing the manufacturing cost and assembly cost of the mobile device light supplement lamp 100.

[0067] Please refer to Figure 1-Figure 5 In some embodiments, the shell body 10 includes a first shell 112 and a second shell 113. The first shell 112 and the second shell 113 are arranged in a split manner, are fixedly connected, and cooperatively form the accommodating cavity 10A.

[0068] Among them, one of the first shell 112 and the second shell 113 can be provided with a plug-in rib, and the other can be provided with a slot. The plug-in rib is inserted into the slot to fix the first shell 112 and the second shell 113 in a plug-in connection. Then, ultrasonic welding can be used to fix the plug-in rib in the slot to improve the stability of the connection between the first shell 112 and the second shell 113.

[0069] The focusing lens 12 is disposed on the outer surface of the first housing 112, and at least a portion of the second housing 113 facing the second lamp assembly 30 is milky white. Thus, the first housing 112 and the second housing 113 can be manufactured separately and then assembled together to complete the entire housing 10, making assembly convenient.

[0070] Please refer to Figure 3-Figure 5 In some embodiments, the first housing 112 and the focusing lens 12 are both made of transparent materials. The mobile device fill light 100 further includes a shielding lining 50 , which can be made of a non-transparent plastic material. The shielding lining 50 is located between the first housing 112 and the first light assembly 20 and has a light-transmitting hole 51 .

[0071] The light emitted by the first lamp group 20 can only be emitted to the first housing 112 through the light-transmitting hole 51. In this way, the shielding lining 50 can shield the circuit board 41 to achieve a beautifying effect.

[0072] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent.

[0073] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
