These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figures 1 to 4 The present embodiment provides an external fill light, which includes a housing 1, a light-transmitting plate 10, and a light-emitting component 2. The housing 1 is constructed as an outer shell of the external fill light, and the interior of the housing 1 is hollow to accommodate relevant functional components and structural components of the external fill light.

[0032] In some embodiments, a light outlet is provided on one side of the housing 1, and the surface of the housing facing away from the light outlet constitutes a mounting surface, and the mounting surface and the light outlet are opposite. The mounting surface is used to be detachably mounted on the smart terminal 8, so that the external fill light can be detachably mounted on the smart terminal 8. The smart terminal 8 can be a mobile phone, tablet computer or other device with a photographing and video recording function. The external fill light is installed on the smart terminal 8 to provide fill light for the smart terminal 8 when shooting, thereby improving the shooting effect of the smart terminal 8.

[0033] In some embodiments, the light-transmitting plate 10 is disposed at the light outlet, and the light in the housing is emitted to the outside of the housing through the light-transmitting plate 10 .

[0034] In some embodiments, the light-transmitting plate 10 is a soft light plate, which is used to soften the light. The soft light plate can completely cover the side of the housing where the light outlet is provided, so that the light emitted from the light outlet must be softened by the soft light plate before being emitted, thereby making the light emitted from the housing softer. In some embodiments, the light-transmitting plate 10 can also be partially provided with a soft light plate, such as providing an opening in the center of the light-transmitting plate 10, and the soft light plate is provided at the central opening of the light-transmitting plate 10.

[0035] In some embodiments, the light emitting assembly 2 includes a light emitting lamp board 21 disposed in the housing and a plurality of light emitting elements 20 disposed at intervals on the light emitting lamp board 21. The light emitting elements 20 can emit light and the light emitted can pass through the light-transmitting plate 10 and be emitted from the housing 1. The light-transmitting plate 10 can soften the light, making the light emitted through the light-transmitting plate 10 softer.

[0036] In some embodiments, multiple light-emitting elements 20 are provided, so that the light emitted from the light-transmitting plate 10 has a high light intensity and can be brighter in a dark environment. The light-emitting light board 21 is arranged at an angle to the plane where the light-transmitting plate 10 is located, so that the light emitted by the light-emitting element 20 will not be emitted directly toward the light-transmitting plate 10, and the light emitted from the light-transmitting plate 10 is further softened, so that the fill light intensity is increased while the fill light is softer, thereby improving the fill light effect of the external fill light and improving the shooting effect of the smart terminal 8. It can be understood that the light-emitting light board 21 is a flat plate structure, and it can be inclined or perpendicular to the plane where the light-transmitting plate 10 is located. The angle between the two can be an acute angle or a right angle. Different angles can be set according to the required soft light requirements.

[0037] In some embodiments, the housing 1 includes a side enclosure 11 extending along its own axial direction and a bottom wall 12 disposed at one end of the side enclosure 11. The side enclosure 11 and the bottom wall 12 can enclose a cavity 13, and the light-emitting component 2 can be accommodated in the cavity 13. The side of the side enclosure facing away from the bottom wall is open to form the above-mentioned light outlet, and the light-transmitting plate 10 is connected to the side enclosure to be able to close and cover the light outlet to make the cavity airtight. The above-mentioned mounting surface is formed on the bottom wall 12, and the inner side surface of the side enclosure 11 constitutes the inner peripheral wall of the cavity 13.

[0038] In some embodiments, the side enclosure 11 may be a hollow rectangular cylinder, and the light-transmitting plate 10 and the bottom wall 12 may be rectangular plates, so that the external fill light has a rectangular cylinder structure as a whole. The side enclosure 11 may also be a hollow circular cylinder, and the light-transmitting plate 10 and the bottom wall 12 may be circular plates, so that the external fill light has a circular cylinder structure as a whole.

[0039] In some embodiments, the light-emitting lamp board 21 is disposed on the inner side surface of the side enclosure, and a plurality of light-emitting elements are disposed on the inner side surface of the light-emitting lamp board 21 at intervals along the circumference of the cavity. The light-emitting elements 20 are electrically connected to the light-emitting lamp board 21, and the light-emitting elements 20 are controlled by the light-emitting lamp board 21. Since there is an angle between the side enclosure 11 and the light-transmitting plate 10, after the light-emitting lamp board 21 is disposed on the inner side surface of the side enclosure 11, an angle is formed between the light-emitting lamp board 21 and the plane where the light-transmitting plate 10 is located. When the light-transmitting plate 10 and the side enclosure 11 are perpendicular, the light-emitting lamp board 21 is perpendicular to the plane where the light-transmitting plate 10 is located.

[0040] In some embodiments, a plurality of light-emitting lamp panels 21 are provided. Each inner side surface of the side enclosure 11 is provided with a light-emitting lamp panel 21. The two ends of each light-emitting lamp panel 21 are abutted against each other in sequence, so that all the light-emitting lamp panels 21 enclose to form a ring, which is adapted to the contour of the side enclosure 11, thereby making the light emitted from the housing more uniform, avoiding the situation of uneven brightness at different positions, and having a better light supplement effect. It can be understood that in this embodiment, when the side enclosure 11 is a rectangular column, it has four inner side surfaces in different directions, so four light-emitting lamp panels 21 are also provided, and each light-emitting lamp panel 21 is attached to one of the inner side surfaces, so as to simplify the manufacturing process of the light-emitting lamp panel 21.

[0041] In some embodiments, the light-emitting lamp panel 21 can also be integrally formed into an annular structure to be adapted to the contour of the side enclosure, so as to avoid splicing of two separate light-emitting lamp panels 21 and improve the light emission uniformity. It can be understood that the outer diameter of the light-emitting lamp panel 21 can be set to cooperate with the inner diameter of the side enclosure 11 to snap the light-emitting lamp panel 21 onto the inner side surface of the side enclosure 11. It can also be in the form of bonding to bond the light-emitting lamp panel 21 to the inner side surface of the side enclosure 11.

[0042] In some embodiments, the side enclosure 11 and the bottom wall 12 are integrally formed, and the light-transmitting plate 10 and the side enclosure 11 are detachably connected. Thus, when the light-emitting component 2 is not installed, the light-transmitting plate 10 can be removed first to open one end of the cavity 13, facilitating the installation of components such as the light-emitting component 2 into the cavity 13, and then connecting the light-transmitting plate 10 to the side enclosure 11 to seal the cavity 13.

[0043] In some embodiments, by making the outer diameter of the light-transmitting plate 10 adapted to the inner diameter of the side enclosure 11, the light-transmitting plate 10 can be snapped onto the inner side surface of the side enclosure 11, so that the light-transmitting plate 10 and the side enclosure 11 are detachably connected. In some embodiments, the light-transmitting plate 10 and the end surface of the side enclosure 11 can also be detachably connected by bonding.

[0044] In some embodiments, the light-emitting lamp panel 21 can be in a long strip shape, and the light-emitting lamp panel 21 can be inclined relative to the light-transmitting plate 10 and arranged in the cavity 13, such as making the light-emitting lamp panel 21 inclined and connected to the bottom wall 12, so that the light-emitting lamp panel 21 forms an included angle with the plane where the light-transmitting plate 10 is located.

[0045] In some embodiments, the light-emitting element 20 can be an LED lamp bead, which uses a solid semiconductor chip as the light-emitting material and has the advantages of energy saving, environmental protection, good color rendering and fast response speed.

[0046] In some embodiments, the external supplementary light also includes a reflector 5 for reflecting light. The reflector 5 is disposed in the cavity 13, and is disposed opposite to the soft light plate. The reflector 5 is located on the side of the light-emitting lamp board 21 away from the soft light plate. In this way, part of the light emitted by the light-emitting element 20 is reflected by the reflector 5 to the soft light plate, making the light emitted from the soft light plate softer.

[0047] See Figure 3 , in some embodiments, the reflector 5 can be parallel to the soft light plate, and the edge of the reflector 5 is in contact with the inner side surface of the side enclosure 11, so that all the light emitted by the light-emitting element 20 can be reflected by the reflector 5 to the soft light plate. Therefore, a part of the light emitted by the light-emitting element 20 directly irradiates the light-transmitting plate 10 to form a first light path S1. Since the light-emitting element 20 is disposed on the side enclosure 11, there is a certain angle between this part of the light and the plane where the light-transmitting plate 10 is located, and it does not irradiate the light-transmitting plate 10 directly. Another part of the light emitted by the light-emitting element 20 directly irradiates the reflector 5 and then irradiates the light-transmitting plate 10 after being reflected by the reflector 5 to form a second light path S2. Through the formed first light path S1 and second light path S2, the light emitted by the light-emitting element 20 finally exits from the light-transmitting plate 10. While setting multiple light-emitting elements 20 to increase the illumination intensity, the light is made softer.

[0048] In some embodiments, the external supplementary light also includes a battery 3 disposed in the cavity 13. The battery 3 is electrically connected to the light-emitting lamp board 21 to supply power to the light-emitting element 20 so that the light-emitting element 20 can emit light. Among them, the battery 3 can be set in a plate shape so that the battery 3 can shorten the thickness in the axial direction of the housing 1. The edge of the battery 3 can be disposed adjacent to the inner side surface of the side enclosure 11 to reduce the space occupied by the battery 3 and have a larger capacity.

[0049] Furthermore, one side of the battery 3 can be in contact with the side of the reflector 5 away from the light-transmitting plate 10 to sandwich the reflector 5 between the light-emitting lamp board 21 and the battery 3, thereby preventing the reflector 5 from shifting.

[0050] In some embodiments, the external supplementary light also includes a wireless charging coil 6. The wireless charging coil 6 is electrically connected to the battery 3, and the battery 3 can supply power to the wireless charging coil 6. Correspondingly, the smart terminal 8 has a radio receiving component, and the wireless charging coil 6 is used to be electrically connected to the radio receiving component so that the battery 3 can charge the smart terminal 8 through the wireless charging coil 6.

[0051] It is understandable that energy is transmitted between the wireless charging coil 6 and the radio receiver using the principle of electromagnetic induction. The wireless charging coil 6 in the housing 1 serves as a transmitter, while the radio receiver in the smart terminal 8 serves as a receiver. When the battery 3 generates a high-frequency current and transmits it to the wireless charging coil 6, the current in the wireless charging coil 6 generates an alternating magnetic field. The radio receiver can also be a coil. When the housing 1 is brought close to the smart terminal 8, the radio receiver senses the change in the magnetic field and converts it into an electric current, thereby charging the smart terminal 8.

[0052] In some embodiments, a first receiving groove 60 adapted to the shape of the wireless charging coil 6 is recessed on the inner side of the bottom wall 12. The wireless charging coil 6 is received in the first receiving groove 60, so that the wireless charging coil 6 is fixed on the bottom wall 12. When the external fill light is connected to the smart terminal 8, the distance between the wireless charging coil 6 and the smart terminal 8 is closer, which is more conducive to generating electromagnetic induction with the radio receiver in the smart terminal 8. The wireless charging coil 6 can also be directly attached to the bottom wall 12 to fix the wireless charging coil 6.

[0053] In some embodiments, the external fill light further includes a control circuit board 4. The control circuit board 4 is disposed in the cavity 13. The control circuit board 4 can be electrically connected to the battery 3 and the light-emitting lamp board 21, so as to control the lighting of the light-emitting element 20 and the charging of the wireless charging coil 6. The control circuit board 4 can be disposed on the same layer as the battery 3 to be received in the cavity 13. A charging interface 40 can be provided on the control circuit board 4, and an opening is provided on the housing 1 at a position corresponding to the charging interface 40. The external fill light can be electrically connected to an external power source through the charging interface 40 to charge the battery 3.

[0054] In some embodiments, the charging interface 40 can also be electrically connected to the smart terminal 8 through a charging cable, so that the external fill light functions as a power bank and can provide emergency charging for the smart terminal 8.

[0055] In some embodiments, the external fill light further includes a magnetic member 7. The magnetic member 7 is disposed in the cavity 13. The bottom wall 12 can be magnetically adsorbed on the smart terminal 8 through the magnetic member 7, so as to fix the external fill light and the smart terminal 8 by magnetic force, freeing the user's hands and facilitating the use of the external fill light.

[0056] In some embodiments, the magnetic member 7 can be a magnet to have magnetic force and be able to adsorb on the smart terminal 8, so that the mounting surface of the housing 1 is detachably connected to the smart terminal 8. In some other embodiments, the mounting surface can also be connected to the smart terminal 8 by bonding to achieve the detachable connection between the two.

[0057] In some embodiments, the magnetic member 7 can be in a ring shape, and the wireless charging coil 6 is located inside the ring of the magnetic member 7. The two are coaxially arranged, which can improve the connection stability between the housing 1 at the position of the wireless charging coil 6 and the smart terminal 8. The magnetic member 7 can be formed by surrounding the wireless charging coil 6 with multiple magnet blocks. It can be understood that the smart terminal 8 has components magnetically attracted to the magnetic member 7, such as metal elements inside it, the metal housing 1, or radio receiving components, etc. The wireless charging coil 6 can also be arranged not inside the ring of the magnetic member 7, but spaced apart from the magnetic member 7 on the bottom wall 12.

[0058] In some embodiments, a second receiving groove 70 adapted to the shape of the magnetic member 7 is recessed on the inner side surface of the bottom wall 12, and the magnetic member 7 is accommodated in the second receiving groove 70. The second receiving groove 70 is in a ring groove shape. By providing the second receiving groove 70 to accommodate the magnetic member 7, the thickness of the housing 1 in the axial direction can be reduced, and the space utilization rate of the cavity 13 can be improved. In some embodiments, the magnetic member 7 can also be directly attached to the bottom wall 12.

[0059] In this embodiment, in the direction from the light-transmitting plate 10 to the bottom wall 12, the light-emitting lamp board 21, the reflector 5, and the battery 3 are sequentially arranged, and the three can be sequentially abutted to be compactly installed in the cavity 13. The side of the battery 3 facing away from the reflector 5 can be abutted against the wireless charging coil 6 and the magnetic member 7, thereby reducing the thickness of the housing 1 and maximizing the use of the space in the cavity 13 to install various components.

[0060] Continue to refer to Figure 5 , this embodiment also provides a shooting system. The shooting system includes the smart terminal 8 and the above-mentioned external fill light. The mounting surface of the external fill light is detachably connected to the smart terminal 8, so that when shooting, the external fill light can be installed on the smart terminal 8 for fill light to improve the fill light effect, and when not needed, the external fill light can be removed from the smart terminal 8 without affecting the normal use of the smart terminal 8.

[0061] It can be understood that the smart terminal 8 can include devices with shooting functions such as mobile phones and tablet computers. A display screen is provided on the front of the smart terminal 8 to display relevant content. A camera is provided on the back of the smart terminal 8 for photography and videography through the camera. When installing the external fill light, the external fill light can be installed on the back of the smart terminal 8, and the mounting surface of the external fill light is installed on the back of the smart terminal 8, so that fill light can be performed when the camera shoots.

[0062] In some embodiments, by installing the mounting surface of the external fill light on the back of the smart terminal 8, the light emitted by the light-emitting element 20 can just illuminate the area directly opposite to the back of the smart terminal 8 after being emitted from the soft light surface, and can better fill light for the camera of the smart terminal 8.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.

[0064] For the sake of explanation, the above description has been presented in connection with specific embodiments. However, the above exemplary discussions are not intended to be exhaustive or to limit the embodiments to the specific forms disclosed above. Many modifications and variations are possible in light of the above teaching.
