DETAILED DESCRIPTION

[0030] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes in different embodiments, which do not deviate from the scope of the present application, and the description and drawings in essence are used for description, not for limiting the present application.

[0031] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indication of direction or position relationship (such as up, down, left, right, front and back, etc.) is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. When the position of these elements is changed, the indication of these directions is also changed accordingly.

[0032] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0033] Since the light source assembly of the light supplement lamp emits light directly to the object, the brightness distribution of the light is uneven, which can easily cause some areas of the face to be too bright, while other areas are very dark, so that some details cannot be displayed in the image, and the imaging effect needs to be improved.

[0034] The present embodiment provides a light supplement lamp, which is specifically illustrated by the following embodiments.

[0035] Figure 1 is a structural schematic view of the light supplement lamp in an embodiment of the present application. Figure 2 is Figure 1exploded view. Figure 3 is Figure 1 cross-sectional view. Figure 4 is Figure 3 enlarged view of part A in

[0036] Referring to Figures 1 to 4 shown, in some embodiments, the light supplement lamp can include a housing 1, a light guide plate 2 and a light source assembly 3. Among them, the housing 1 can provide accommodation space for the light guide plate 2 and the light source assembly 3. The light source assembly 3 can emit light. The light emitted by the light source assembly 3 can be emitted from one side of the housing 1 after being reflected or refracted by the light guide plate 2. After the light of the present application is processed by the light guide plate 2, the light can be uniformly emitted from the housing 1 to meet the user's light efficiency requirements for the camera light.

[0037] Referring to Figure 1 and Figure 2 shown, in some embodiments, the housing 1 can be annular. The housing 1 can be provided with an annular mounting space 10 inside. The mounting space 10 can be used to accommodate the light guide plate 2 and the light source assembly 3. By arranging the light source assembly 3 in the mounting space 10, the light source assembly 3 can be in a relatively stable working environment, and the anti-vibration performance is good, which is conducive to improving the working stability of the light source assembly 3.

[0038] In some embodiments, the housing 1 can include a front shell 11 and a rear shell 12. The light guide plate 2 and the light source assembly 3 are arranged between the front shell 11 and the rear shell 12. The front shell 11 can be detachably arranged on one side of the rear shell 12. The front shell 11 and the rear shell 12 can be enclosed to form a mounting space 10. Thus, the mounting space 10 can be opened by the front shell 11 to enable replacement and maintenance of the light guide plate 2 and the light source assembly 3 in the mounting space 10.

[0039] In some embodiments, one side surface of the housing 1 can be provided with a first light exit surface 13 that transmits light. Specifically, in the present embodiment, the first light exit surface 13 can be arranged on the front shell 11. The surface area of the first light exit surface 13 can be less than or equal to the surface of the front shell 11 opposite to it. Thus, the light emitted by the light source assembly 3 can be emitted from the housing 1 by using the first light exit surface 13, thereby realizing light supplement for photography.

[0040] Referring to Figures 2 to 4As shown, in some embodiments, the light guide plate 2 can be arranged in the housing 1. The light guide plate 2 can be annular. The light guide plate 2 can be arranged in the mounting space 10. A light-transmitting light guide surface 21 can be annularly arranged on the outer circumferential side of the light guide plate 2. The light source assembly 3 is arranged on the outer circumferential side of the light guide plate 2, and the light source assembly 3 can emit light rays toward the light guide surface 21. The light rays emitted by the light source assembly 3 can pass through the light guide surface 21 and enter the light guide plate 2, and the light rays entering the light guide plate 2 can be refracted and / or reflected multiple times in the light guide plate 2, so that the light rays can be uniformly emitted from the light guide plate 2, and through the refraction and / or reflection of the light rays by the light guide plate 2, the light rays emitted by the light source assembly 3 can be made more uniform and softer.

[0041] In some embodiments, the side of the light guide plate 2 close to the first light exit surface 13 can be a second light exit surface 22. The second light exit surface 22 can be arranged opposite the first light exit surface 13. The light rays emitted by the light source assembly 3 toward the light guide plate 2 can be emitted by the second light exit surface 22 onto the first light exit surface 13 after multiple refractions and reflections by the light guide plate 2, and then emitted from the first light exit surface 13 to the outside of the housing 1. Thus, after the light rays emitted by the light source assembly 3 toward the light guide surface 21 enter the light guide plate 2, the light rays can be reflected and / or refracted in the light guide plate 2, so that the light rays can be uniformly emitted from the first light exit surface 13 of the housing 1 after passing through the second light exit surface 22 of the light guide plate 2, thereby ensuring that the light rays emitted by the light guide plate are uniform in brightness, thereby improving the light supplementing effect of the light supplementing lamp and avoiding obvious shadows in photography and videography, thereby meeting the light efficiency requirements of users for light supplementing light. In particular, when a user uses the light supplementing lamp of the present application for portrait photography, the light supplementing lamp can better represent the skin texture of a person, thereby effectively improving the picture quality.

[0042] In some embodiments, the light guide plate 2 can be annular. The outer contour of the light guide plate 2 can be circular, so that the outer contour of the housing 1 can also be circular.

[0043] It should be noted that in other embodiments, the outer contour of the light guide plate 2 can be rectangular, so that the outer contour of the housing 1 can also be rectangular.

[0044] It should also be noted that in other embodiments, the outer contour of the light guide plate 2 can be other shapes, and the outer contour of the housing 1 can be adaptively changed so that the light guide plate 2 can be accommodated in the housing 1.

[0045] Please refer to Figures 2 to 4 As shown, in some embodiments, the outer circumferential side of the light guide plate 2 can be provided with the light source assembly 3. The light source assembly 3 can be used to emit light rays to the light guide plate 2, so that the light rays can be emitted from the housing 1 to supplement light for the user.

[0046] In some embodiments, the light source assembly 3 can include a flexible light plate 31 and a lamp bead 32 arranged on the light plate 31. The flexible light plate 31 can be arranged around the outer circumferential side of the light guide plate 2. The lamp bead 32 can be arranged between the light plate 31 and the light guide plate 2. The lamp bead 32 can emit light rays towards the light guide surface 21. The lamp bead 32 can be a light-emitting diode, which consumes less power and has high stability, thereby being suitable for long-time photo and video shooting.

[0047] It should be noted that in other embodiments, the lamp bead 32 can also use other light-emitting components, which are not limited herein.

[0048] Figure 5 is Figure 1 a sectional view. Figure 6 is Figure 5 an enlarged view of part B in

[0049] Referring to Figure 2 and Figure 5 , in some embodiments, the outer circumference of the light guide plate 2 can be provided with a receiving groove 23. The receiving groove 23 is formed by inwardly recessing the outer side wall of the light guide plate 2. The groove inner wall of the receiving groove 23 can serve as the light guide surface 21 of the light guide plate 2. The receiving groove 23 can be used to accommodate the lamp bead 32. The light rays emitted by the lamp bead 32 can enter the light guide plate 2 through the groove inner wall of the receiving groove 23, and then be emitted from the first light exit surface 13 on the housing 1 through the second light exit surface 22 of the light guide plate 2. Thus, the use of the receiving groove 23 has the effect of positioning and limiting the lamp bead 32. The receiving groove 23 can provide the lamp bead 32 with a mounting space 10, realizing the positioning and mounting of the light source assembly 3 on the light guide plate 2.

[0050] It should be noted that in other embodiments, the receiving groove 23 can be arranged on the inner circumferential wall of the light guide plate 2, i.e. the light guide surface 21 can be arranged on the inner circumferential wall of the light guide plate 2. The lamp bead 32 can be arranged around the inner circumferential side of the light guide plate 2.

[0051] In some embodiments, the light plate 31 can be arranged around the outer circumference of the receiving groove 23, so that the receiving groove 23 can be covered by the light plate 31, thereby effectively reducing the light leakage in the receiving groove 23, and improving the utilization rate of the light emitted by the lamp bead 32. In addition, through the light guide surface 21 at the receiving groove 23, the light emitted by the lamp bead 32 can enter the interior of the light guide plate 2 as much as possible and at multiple angles, which is conducive to the uniform diffusion of the light to the entire light guide plate 2, greatly improving the overall soft light effect.

[0052] Referring to Figure 5As shown, in some embodiments, the inner wall of the accommodating groove 23 can be arc-shaped, i.e., the light guide surface 21 can be arc-shaped. The arc-shaped surface can make the light emitted by the lamp bead 32 enter the interior of the light guide plate 2 more uniformly, thereby more favorably ensuring that the light is emitted with uniform brightness.

[0053] In some embodiments, when the outer contour of the light guide plate 2 is circular, the arc-shaped surface can be concavely formed towards the center of the light guide plate 2. In this way, the light emitted by the lamp bead 32 can enter the interior of the light guide plate 2 more uniformly.

[0054] It should be noted that, in other embodiments, when the outer contour of the light guide plate 2 is rectangular, the arc-shaped surface can be concavely formed towards the center line of the light guide plate 2. In this way, the light emitted by the lamp bead 32 can enter the interior of the light guide plate 2 more uniformly.

[0055] Please refer to Figure 5 As shown, in some embodiments, after the lamp bead 32 is installed in the accommodating groove 23, there is a gap between the light guide surface 21 and the surface of the lamp bead 32, which can effectively prevent the lamp bead 32 from being damaged due to the extrusion of the light guide plate 2 under the action of external forces such as collision.

[0056] Please refer to Figure 5 As shown, in some embodiments, the accommodating groove 23 can be provided in plurality. The plurality of accommodating grooves 23 can be arranged at intervals on the outer circumferential side of the light guide plate 2. The lamp bead 32 can be provided in plurality. The plurality of lamp beads 32 can be arranged at intervals on the outer side of the light guide plate 2. Each lamp bead 32 can be arranged in a corresponding accommodating groove 23. Among them, the lamp beads 32 in adjacent accommodating grooves 23 can emit light of the same color or different colors to bring users a variety of light effects and effectively improve the user's experience. For example, the lamp bead 32 in one accommodating groove 23 emits green light, and the lamp beads 32 in the two adjacent accommodating grooves 23 emit red light and blue light, respectively, which is equivalent to that the lamp beads 32 can emit light in the arrangement mode of "red, green, blue, red, green, blue"; or, the lamp bead 32 in one accommodating groove 23 emits warm light, and the lamp beads 32 in the adjacent accommodating grooves 23 emit cold light, which is equivalent to that the lamp beads 32 in every two adjacent accommodating grooves 23 can emit light in the arrangement mode of "cold, warm, cold, warm".

[0057] It should be noted that, in other embodiments, two lamp beads 32, three lamp beads 32, or more lamp beads 32 can be arranged in one accommodating groove 23, which can be set according to actual needs, and is not limited herein.

[0058] In some embodiments, the rated power of each lamp 32 in adjacent receiving slots 23 may be different. For example, the rated power of the lamp 32 in one receiving slot 23 is high, while the rated power of the lamp 32 in the receiving slots 23 on its adjacent sides is low. This can produce a three-dimensional supplementary lighting effect and meet diverse supplementary lighting needs.

[0059] Please see Figure 2 and Figure 3 As shown, in some embodiments, the supplementary light may include a first reflector 4. The first reflector 4 may be disposed within the mounting space 10 of the housing 1. The first reflector 4 may be annular. The first reflector 4 may be arranged around the side of the light guide plate 2 facing away from the light guide surface 21, that is, the first reflector 4 may be arranged around the inner circumference of the light guide plate 2. The first reflector 4 can reflect light emitted from the side of the light guide plate 2 facing away from the light guide surface 21, so that the light reflected by the first reflector 4 is reflected again from the side of the light guide plate 2 facing away from the light guide surface 21 and back into the light guide plate 2. Thus, by using the first reflector 4, the light emitted by the light source assembly 3 will not be emitted from the side wall of the light guide plate 2 corresponding to the first reflector 4 to the outside of the housing 1, thereby effectively reducing light loss and increasing the amount of light emitted from the side of the light guide plate 2 near the first light-emitting surface 13, thereby effectively increasing the light utilization rate and thus improving the overall lighting efficiency of the supplementary light.

[0060] It should be noted that in some other embodiments, the first reflector may not be provided on the inner circumferential side of the light guide plate 2, but a reflective film may be coated on the inner circumferential side of the light guide plate 2.

[0061] In some embodiments, the supplementary light may include a second reflector 5. The second reflector 5 may be disposed within the mounting space 10 of the housing 1. The second reflector 5 may be annular. The second reflector 5 may be arranged around the end of the light guide plate 2 facing away from the first light-emitting surface 13. The second reflector 5 can reflect light emitted from the side of the light guide plate 2 facing away from the first light-emitting surface 13, so that the light reflected by the second reflector 5 is reflected again from the side of the light guide plate 2 facing away from the first light-emitting surface 13 and back into the light guide plate 2. Thus, by using the second reflector 5, the light emitted by the light source assembly 3 can be prevented from escaping from the side wall of the light guide plate 2 corresponding to the second reflector 5 to the outside of the housing 1, thereby effectively reducing light loss and increasing the amount of light emitted from the side of the light guide plate 2 closer to the first light-emitting surface 13, thereby effectively increasing the light utilization rate and improving the overall lighting efficiency of the supplementary light.

[0062] It should be noted that in some other embodiments, a second reflector may not be provided at the end of the light guide plate 2 that is away from the first light emitting surface 13, but instead a reflective film may be coated on the end of the light guide plate 2 that is away from the first light emitting surface 13.

[0063] In some embodiments, the light emitted by the light source assembly 3 can enter the light guide plate 2 through the light guide surface 21 for reflection and / or refraction, and the light emitted from the surface of the light guide plate 2 can be reflected by the first reflecting plate 4 and the second reflecting plate 5 and then emitted from the first light emitting surface 13. Thus, by cooperation of the first reflecting plate 4 and the second reflecting plate 5, the light entering the light guide plate 2 can only be emitted from the surface of the light guide plate 2 close to the first light emitting surface 13, and then emitted from the first light emitting surface 13 of the shell 1 to achieve the light compensation for the user. Thus, by using the first reflecting plate 4 and the second reflecting plate 5, the loss of light can be effectively reduced, and the utilization rate of the light emitted by the light source assembly 3 can be effectively increased, thereby facilitating the improvement of the overall illumination efficiency of the light compensation lamp.

[0064] In some embodiments, the light compensation lamp comprises a diffusion plate 6. The diffusion plate 6 can be arranged inside the shell 1. The diffusion plate 6 can be arranged between the second light emitting surface 22 of the light guide plate 2 and the first light emitting surface 13 of the shell 1. The light emitted from the second light emitting surface 22 of the light guide plate 2 can pass through the diffusion plate 6 and then be emitted from the first light emitting surface 13 of the shell 1. The arrangement of the diffusion plate 6 can cause the light entering the diffusion plate 6 to be reflected, refracted and scattered several times, so that the light is uniformly dispersed on the diffusion plate 6, thereby further facilitating the obtaining of a uniform light effect.

[0065] It should be noted that in other embodiments, the diffusion plate 6 can also be arranged outside the shell 1. Specifically, the diffusion plate 6 can be arranged on the first light emitting surface 13 of the shell 1. The light emitted by the lamp beads 32 can be emitted from the first light emitting surface 13 of the shell 1 and then emitted from the diffusion plate 6.

[0066] Please refer to Figures 1 to 3 In some embodiments, the shell 1 can comprise a power supply compartment 14. The power supply compartment 14 can comprise a mounting groove 141. The power supply compartment 14 can be arranged on the side of the rear shell 12 away from the front shell 11. The power supply compartment 14 can be arranged on the rear shell 12. The mounting groove 141 can be in communication with the mounting space 10. The mounting groove 141 can be used to mount the battery 16. The battery 16 can be electrically connected to the light source assembly 3 in the mounting space 10 through the mounting groove 141, thereby supplying power to the light source assembly 3.

[0067] It should be noted that in other embodiments, the battery 16 can be directly arranged in the shell 1, so that the power supply can be arranged in the mounting space 10 to supply power to the light source assembly 3.

[0068] Please refer to Figure 2As shown, in some embodiments, the light supplement lamp further comprises a key circuit board 7. The key circuit board 7 can be arranged inside the shell 1. The battery 16 can be electrically connected with the key circuit board 7, so that the battery 16 can supply power to the key circuit board 7. The key circuit board 7 is also electrically connected with the light source assembly 3. The key circuit board 7 is provided with at least one touch point. Touching the touch point can control the light-on and light-off, brightness, color temperature, color, etc. of the lamp beads 32. This embodiment takes three touch points as an example for illustration.

[0069] In some embodiments, the light supplement lamp comprises keys 8. The keys 8 correspond to the touch points on the key circuit board 7. Therefore, it can be understood that the keys 8 in this embodiment are provided with three. The three keys 8 can be integrally arranged, thereby facilitating the one-time installation of the keys 8 on the key circuit board 7. One end of the key 8 can protrude from the side wall of the rear shell 12, or be flush with the side wall of the rear shell 12. The user can press each key 8 to control the opening and closing, brightness, color temperature, color, etc. of the lamp beads 32.

[0070] Please refer to Figure 1 As shown, in some embodiments, the middle part of the shell 1 can be provided with a mounting hole 15. The mounting hole 15 can be mounted with a mirror 17, so that the light supplement lamp can be used as a makeup mirror.

[0071] It should be noted that, in other embodiments, the mounting hole 15 can be used to mount a display screen, so that the light supplement lamp can be used as a display device.

[0072] In some embodiments, the light supplement lamp can comprise a mounting assembly 9. The mounting assembly 9 can be arranged on one side of the shell 1 and can be used to support and fix the shell 1. Thus, the light supplement lamp can be supported on the desktop by the mounting assembly 9, thereby facilitating the support and fixation of the light supplement lamp for the use of the light supplement lamp.

[0073] In some embodiments, the mounting assembly 9 can comprise a clamping piece 91. The clamping piece 91 can comprise a control end 911 and a clamping end 912. The user can adjust the opening angle of the clamping end 912 through the control end 911, so as to clamp and fix the whole base on an external device. The external device can be a mobile phone, so that when the user takes a selfie with the mobile phone, the light supplement lamp can provide uniform and soft light effect for the user, significantly improving the imaging effect when the user takes a selfie.

[0074] In some embodiments, the mounting assembly 9 can comprise a rotating shaft 92. The clamping piece 91 can be rotatably connected with the shell 1 through the rotating shaft 92, so that the shell 1 can rotate relative to the clamping piece 91 around the axis direction of the rotating shaft 92, thereby being able to adjust the inclination angle of the first light emitting surface 13 of the shell 1 relative to the external device, and thereby being able to direct the light to the desired direction to obtain the desired light effect.

[0075] Specifically, the clamping piece 91 can be rotatably connected with the power supply bin 14 through the rotating shaft 92, and then the inclination angle of the power supply bin 14 and the external device can be adjusted, so that the inclination angle of the first light emitting surface 13 of the shell 1 relative to the external device is adjusted through the power supply bin 14, and then the light can be shot to the required direction, so as to obtain the required light effect.

[0076] The above embodiments are only illustrative of the structure, and the structures in the embodiments are not fixedly combined. In the absence of structural conflicts, the structures in the embodiments can be arbitrarily combined.

[0077] Although the present application has been described with reference to several exemplary embodiments, it is understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present application can be embodied in various forms without departing from the spirit or essential characteristics thereof, it is understood that the above-described embodiments are not limited to any particular details, but are to be interpreted broadly within the spirit and scope of the appended claims, therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are intended to be embraced by the claims.
