[0003] The present application belongs to the field of communication technology, and specifically relates to an electronic device. BACKGROUND
[0004] With the continuous improvement of the imaging function of electronic devices such as mobile phones, the demand for taking pictures with electronic devices is also increasing, and the shooting scenes are endless. For scenes such as dark light environment and night scene shooting, it is difficult to take clear photos, and video recording or live streaming scenes are also difficult to have a good experience.

[0006] However, in the related technology, the light supplement lamp is located on one side of the camera module, at this time, the light supplement lamp and the camera module are eccentrically arranged, which causes the light supplement range of the light supplement lamp to be offset from the shooting field of view range of the camera module, thereby causing the light supplement lamp to be difficult to achieve uniform light supplement effect when the electronic device is shooting, and thus affecting the image shooting effect of the electronic device. SUMMARY

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.
[0020] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.
[0021] The electronic device provided by the embodiments of the present application will be described in detail below with reference to the drawings, through specific embodiments and their application scenarios.
[0022] Please refer to Figs. 1-9, the electronic device disclosed by the embodiments of the present application includes a housing 100, a camera decoration 210, a light-transmitting annular member 220, and a light supplement assembly 400.
[0023] The shell 100 provides a mounting base for other components of the electronic device. Different structures of the shell 100 form different components. For example, the shell 100 can include a front shell, a rear cover, and a middle frame arranged between the two. For another example, the shell 100 includes a front cover and a rear cover, and a frame is formed on the front cover or the rear cover, and the frame is located between the front cover and the rear cover. The rear cover here can be a battery cover.
[0024] The camera decoration piece 210 is arranged on the shell 100, and the camera decoration piece 210 is used to cover the camera module arranged in the shell 100, so as to avoid the camera module device exposed. Specifically, the shell 100 is provided with an inner cavity and a mounting hole communicating with the inner cavity, and the camera module can be mounted in the inner cavity. The mounting hole is used to mount the camera decoration piece 210. The camera decoration piece 210 is provided with an opening, and the opening is arranged opposite to the camera module, so that the camera module can work through the opening. The camera decoration piece 210 here can cover the mounting hole, and the opening is a light transmission hole arranged in a local area of the camera decoration piece 210. Or the camera decoration piece 210 can also be an annular structure, and the above-mentioned opening is an inner ring area of the camera decoration piece 210.
[0025] The edge of the camera decoration piece 210 disclosed in the present application is provided with an annular groove 2121, and the annular groove 2121 extends along the circumferential direction of the camera decoration piece 210. Since the annular groove 2121 is arranged at the edge position of the camera decoration piece 210, and its extension direction also extends along the circumferential direction of the camera decoration piece 210, the annular groove 2121 is arranged around the opening. The light transmission annular piece 220 covers the slot of the annular groove 2121 to form an annular accommodating cavity 201 with the annular groove 2121. At this time, the light transmission annular piece 220 covers the slot of the annular groove 2121, so that the annular groove 2121 forms a closed annular accommodating cavity 201. The extension direction of the light transmission annular piece 220 here is the same as that of the annular groove 2121.
[0026] The light transmission annular piece 220 can transmit light, so the light transmission annular piece 220 can be made of glass, resin and other materials that can transmit light. Of course, the light transmission annular piece 220 can also be made of other materials, which are not limited herein.
[0027] The light supplement assembly 400 is used to supplement light for the shooting scene, so as to improve the image shooting effect of the electronic device. The light supplement assembly 400 includes an annular light guide piece 410, a first light emitting source 420 and a second light emitting source 430. The first light emitting source 420 and the second light emitting source 430 can be LED (Light Emitting Diode, semiconductor light emitting diode) lamp, high-pressure sodium lamp, metal halide lamp, etc. Of course, the first light emitting source 420 and the second light emitting source 430 can also be other structures, which are not limited herein.
[0028] The annular light guide 410 is a light transmission component, and the light emitted by the first light emitting source 420 and the second light emitting source 430 is transmitted through the annular light guide 410. The annular light guide 410, the first light emitting source 420, and the second light emitting source 430 are all arranged in the annular accommodating cavity 201. At this time, the light supplement assembly 400 is arranged in the annular accommodating cavity 201 formed by the camera decoration 210. The annular light guide 410 is arranged opposite to the light-transmitting annular member 220, and at this time, the light emitted by the light supplement assembly 400 is transmitted through the annular light guide 410 and then transmitted to the outside of the electronic device by the light-transmitting annular member 220.
[0029] As shown in FIG. 9, in the embodiment of the present application, the annular light guide 410 has a first end face 4101 and a second end face 4102 at two ends thereof, respectively. The first end face 4101 is arranged opposite to the first light emitting source 420, and the second end face 4102 is arranged opposite to the second light emitting source 430. The annular light guide 410 in the present application is an arc-shaped strip structure, and at this time, a gap is formed between the first end face 4101 and the second end face 4102, which is used for arranging the first light emitting source 420 and the second light emitting source 430. In the present application, in order to make the light emission shape of the annular light guide 410 close to a ring shape, the distance between the first end face 4101 and the second end face 4102 needs to be small enough, but also needs to meet the installation size of the first light emitting source and the second light emitting source 430.
[0030] The shape of the annular light guide 410 placed in the annular accommodating cavity 201 is shown in FIG. 9. The annular light guide 410 can be made of rigid light-transmitting material, such as glass. At this time, the shape of the annular light guide 410 is the same as that of the annular accommodating cavity 201. Of course, the annular light guide 410 can be made of flexible light-transmitting material, such as optical fiber. At this time, the annular light guide 410 can be a flexible straight strip structure when it is not placed in the annular accommodating cavity 201, and when it is placed in the annular accommodating cavity 201, the shape of the annular light guide 410 is controlled by the shape of the annular accommodating cavity 201, so that the annular light guide 410 forms a ring structure.
[0031] The light emitted by the first light emitting source 420 enters the annular light guide 410 through the first end face 4101 and then is transmitted along the circumferential direction of the annular light guide 410 to the direction of the second end face 4102. The light emitted by the second light emitting source 430 enters the annular light guide 410 through the second end face 4102 and then is transmitted along the circumferential direction of the annular light guide 410 to the direction of the first end face 4101.
[0032] The annular light guide 410 is provided with a plurality of reflection tooth patterns 412, and the plurality of reflection tooth patterns 412 are arranged at intervals along the extension direction of the annular light guide 410. The reflection tooth pattern 412 here is for the purpose of improving the light emission of the annular light guide 410. The reflection tooth pattern 412 is a recessed structure engraved on the annular light guide 410, and the reflection tooth pattern 412 has a certain depth, and the side wall of the reflection tooth pattern 412 can reflect and refract light. When the light emitted by the first light emitting source 420 and the second light emitting source 430 enters the annular light guide 410, most of the light will propagate along the extension direction of the annular light guide 410, so that the light propagates in the annular light guide 410 without spilling out, thereby reducing the brightness of the light supplement assembly 400. The present application sets the reflection tooth pattern 412 on the annular light guide 410, which can make the reflection angle of the light incident into the annular light guide 410 change sharply, so that the light can spill out of the annular light guide 410, thereby improving the brightness of the light supplement assembly 400.
[0033] In a specific light supplement process, the light emitted by the first light emitting source 420 and the second light emitting source 430 enters the annular light guide 410 through the corresponding first end surface 4101 or second end surface 4102, and is reflected by the reflection tooth pattern 412 on the annular light guide 410 and then emitted from the light-transmitting annular member 220.
[0034] In the embodiments disclosed in the present application, the annular light guide 410 can be arranged along the edge of the camera decoration member 210, so that the light supplement assembly 400 is arranged around the edge of the camera decoration member 210. At this time, the light supplement assembly 400 is a ring-shaped hollow structure. Since the light supplement assembly 400 is arranged at the edge of the camera decoration member 210, the light supplement assembly 400 can supplement light along the circumference of the camera module, thereby avoiding the offset of the light supplement assembly 400 and the camera module, and thus the light supplement range of the light supplement assembly 400 can fall within the shooting field of view of the camera module as much as possible. Therefore, the electronic device can achieve a more uniform light supplement effect when shooting, thereby improving the shooting effect of the electronic device.
[0035] In addition, the light supplement lamp in the related art is usually arranged in the shell 100 of the electronic device, thereby occupying a large internal space of the shell 100. The light supplement assembly 400 disclosed in the present application is separated from the shell 100 and arranged on the camera decoration member 210, thereby saving part of the internal space of the shell 100 and being more conducive to the functional upgrade of the electronic device.
[0036] In the embodiments disclosed in the present application, the light-emitting light source is arranged at both ends of the annular light guide member 410, so that the annular light guide member 410 simultaneously transmits light from both ends to the middle region, so that the light-emitting in the entire region of the annular light guide member 410 is relatively uniform, thereby avoiding the problem of uneven light-emitting brightness. Therefore, the light supplement lamp assembly 400 disclosed in the present application can realize the effect of circumferentially uniform light-emitting of the annular light-emitting surface.
[0037] In addition, the annular light guide member 410 is provided with a plurality of reflection tooth patterns 412, which can further improve the light-emitting brightness of the light supplement lamp assembly 400.
[0038] The light supplement lamp assembly in the present application has uniform light-emitting and high brightness, and the light supplement range of the light supplement lamp assembly 400 falls within the photographing field of view of the camera module as much as possible, so that the electronic device has a good light supplement effect.
[0039] The light-emitting uniformity of the light supplement lamp assembly 400 is closely related to the light transmission performance of the annular light guide member 410. If the light transmission loss in the annular light guide member 410 is large, the brightness of the position far from the light-emitting light source of the annular light guide member 410 will be poor.
[0040] Based on this, in another optional embodiment, the first end surface 4101 and the second end surface 4102 can be provided with a light distribution structure 411. The light distribution structure 411 can include a plurality of annular teeth, and the plurality of annular teeth can be continuously arranged along the radial direction of the first end surface 4101 or the second end surface 4102. In this scheme, under the action of the light distribution structure 411, the propagation angle of the light emitted by the light-emitting light source after being incident on the annular light guide member 410 is less than the total reflection angle, so that the propagation loss of the light is reduced, thereby enabling the light to uniformly fill the entire annular light guide member 410, and thereby improving the light-emitting uniformity of the light supplement lamp assembly 400.
[0041] In addition, the distance between the end surface of the annular light guide member 410 and the light-emitting light source in the present application is close, so that the light-emitting light source is a surface light source relative to the end surface of the annular light guide member 410. The light distribution structure 411 in the present application adopts a plurality of annular teeth, and the plurality of annular teeth as the light distribution structure 411 can cover the entire surface light source, so that the annular light guide member 410 has better light distribution performance. Therefore, the present application adopts a plurality of annular teeth as the light distribution structure 411, which can further reduce the light transmission loss.
[0042] Optionally, the spacing between the plurality of annular teeth is the same, and the plurality of annular teeth are concentrically arranged. Of course, the plurality of annular teeth can also have other arrangement modes, which are not limited herein.
[0043] In an optional solution, the plurality of annular teeth can be a concentric tooth structure. By precisely controlling the inclination angle and tooth depth of the annular teeth, the angle of light entering the annular light guide 410 can be controlled, thereby improving the light efficiency of the light supplement assembly 400.
[0044] As shown in FIG. 7, the angle between the side wall of the annular tooth and the horizontal plane is the inclination angle of the annular tooth, the inclination angle of the annular tooth is the angle a shown in FIG. 7, and the distance from the tooth root to the tooth top of the annular tooth is the tooth depth, which is the height h. By adjusting the inclination angle a and the tooth depth h, precise light control can be achieved.
[0045] Optionally, the tooth depth h can be 0.12 mm, and h can float between plus and minus 0.05 mm. The inclination angle a can be 20.93°, and a can float between plus and minus 5.5°.
[0046] The diameters of the first end surface 4101 and the second end surface 4102 described above are the light entrance aperture, which is D shown in FIG. 7. The light entrance aperture can be 1 mm to 3 mm, and specifically, the light entrance aperture can be 1.7 mm, that is, the diameters of the first end surface 4101 and the second end surface 4102 can be 1.7 mm.
[0047] In the above embodiment, the annular light guide 410 can include an outlight side 4103 and a light reflection side 4104 arranged opposite to each other. The outlight side 4103 can be opposite to the light transmission annular member 220, and at this time, the light reflection side 4104 is the side of the annular light guide 410 away from the light transmission annular member 220, which can also be understood as the side of the annular light guide 410 opposite to the groove bottom of the annular groove 2121 being the light reflection side 4104, and the side opposite to the groove opening being the outlight side 4103. That is, the light of the annular light guide 410 is emitted from the outlight side 4103 to the light transmission annular member 220.
[0048] In an optional solution, as shown in FIG. 4, a plurality of reflection teeth 412 can be arranged on the light reflection side 4104. At this time, when the light is incident on the reflection teeth 412, the light is reflected by the reflection teeth 412 from the light reflection side 4104 to the outlight side 4103, and then emitted from the outlight side 4103 to the light transmission annular member 220. In this solution, the light is reflected once by the reflection teeth 412 arranged on the light reflection side 4104 and then emitted from the outlight side 4103, so that the transmission path of the light is relatively short, thereby improving the light utilization efficiency of the light supplement assembly 400, and thus improving the brightness of the light supplement assembly 400.
[0049] In another alternative, as shown in FIG. 5, a plurality of reflection teeth 412 can be arranged on the light emitting side 4103. In this case, when the light is incident on the reflection teeth 412, the light is reflected by the reflection teeth 412 from the light emitting side 4103 to the light reflecting side 4104, and then is reflected by the light reflecting side 4104 and the bottom of the annular groove 2121 to the light emitting side 4103, and then is emitted from the light emitting side 4103 to the light transmitting annular member 220. This scheme can increase the reflection and refraction times of the light, so that the light emitted has better expansion, thereby improving the range of the light spot.
[0050] In another alternative embodiment, the depth of the reflection teeth 412 decreases from the center of the annular light guide 410 to the two ends of the annular light guide 410. Here, the depth of the reflection teeth 412 can be understood as the distance between the bottom and the top of the reflection teeth 412. Here, the top can be understood as the surface of the annular light guide 410. In this case, the distance from the bottom to the top of the reflection teeth 412 decreases from the center of the annular light guide 410 to the two ends of the annular light guide 410. That is, the distance from the two ends of the annular light guide 410 to the light source is relatively short, and the depth of the reflection teeth 412 is small, thereby reducing the reflection performance of the light. The closer to the center of the annular light guide 410, the farther the distance from the light source, and the deeper the depth of the reflection teeth 412, thereby improving the reflection performance of the light. Therefore, by adjusting the depth of the reflection teeth 412, the reflection performance of different regions of the annular light guide 410 is adjusted, and the overall light emitting intensity of the light transmitting annular member 220 is accurately balanced.
[0051] In another alternative, as shown in FIG. 8, the eccentric distance of the bottom of the reflection teeth 412 relative to the center axis of the annular light guide 410 can also represent the depth of the reflection teeth 412. Here, the center axis of the annular light guide 410 refers to the axis that extends along the annular light guide 410 and passes through the center of its cross section. The axis shown by the dashed line in FIG. 8 is the center axis of the annular light guide 410. From the center of the annular light guide 410 to the two ends of the annular light guide 410, the eccentric distance of the bottom of the reflection teeth 412 relative to the center axis of the annular light guide 410 gradually increases. The distance shown by d in FIG. 8 is the eccentric distance of the bottom of the reflection teeth 412 relative to the center axis of the annular light guide 410. The greater the eccentric distance of the bottom of the reflection teeth 412 relative to the center axis of the annular light guide 410, the smaller the distance from the bottom of the reflection teeth 412 to the surface of the annular light guide 410, and therefore the shallower the depth of the reflection teeth 412. The smaller the eccentric distance of the bottom of the reflection teeth 412 relative to the center axis of the annular light guide 410, the greater the distance from the bottom of the reflection teeth 412 to the surface of the annular light guide 410, and therefore the deeper the depth of the reflection teeth 412.
[0052] In a specific scheme, as shown in Table 1 below:
[0053] Table 1
[0054] The percentages in the above Table 1 represent the normalized length position of the annular light guide 410, where the distance from the first end surface 4101 to the second end surface 4102 changes from 0% to 100% sequentially. d represents the eccentric distance of the bottom of the reflection tooth 412 relative to the central axis of the annular light guide 410. At this time, the closer the annular light guide 410 is to the middle position along its extension direction, the smaller the eccentric distance, and the deeper the depth of the reflection tooth 412; the closer the annular light guide 410 is to the end position along its extension direction, the larger the eccentric distance, and the shallower the depth of the reflection tooth 412.
[0055] Of course, the eccentric distance of the bottom of the reflection tooth 412 relative to the central axis of the annular light guide 410 is not limited to the above-mentioned numerical value, and the above-mentioned data parameter can float between plus and minus 0.05 mm.
[0056] In an alternative scheme, the extension direction of the reflection tooth 412 is parallel to the axial direction of the annular light guide 410. Here, the extension direction of the reflection tooth 412 refers to the direction of the largest dimension of the reflection tooth 412, and the largest dimension of the reflection tooth 412 is its length direction, and the axial direction of the annular light guide 410 refers to the extension direction of the annular light guide 410.
[0057] In another alternative scheme, the extension direction of the reflection tooth 412 intersects the axial direction of the annular light guide 410. In this scheme, the extension direction of the reflection tooth 412 intersects the axial direction of the annular light guide 410, so that the extension direction of the reflection tooth 412 is along the circumferential direction of the annular light guide 410, so that each reflection tooth 412 can cover a larger position, thereby ensuring that most of the light can be incident on the reflection tooth 412, further improving the reflection efficiency.
[0058] Further, the extension direction of the reflection tooth 412 can be perpendicular to the axial direction of the annular light guide 410. This scheme can further improve the light brightness and uniformity of the light supplement lamp assembly 400.
[0059] In another alternative embodiment, as shown in FIG. 8, the distance between the centers of any two adjacent reflection teeth 412 is equal. The distance shown as I in FIG. 8 is the distance between the centers of the two adjacent reflection teeth 412. This scheme can further improve the light uniformity of the light supplement lamp assembly 400.
[0060] In an alternative, the reflective tooth 412 can include a first bevel 412a and a second bevel 412b, the first bevel 412a and the second bevel 412b intersect. The first bevel 412a and the second bevel 412b intersect to form an included angle as shown by P in FIG. 8. At this time, the reflective tooth 412 is a "V" shaped groove structure, and the two bevels of the reflective tooth 412 are reflective surfaces, so that the light is reflected by the two bevels. In this scheme, the structure of the reflective tooth 412 is simple, and has good reflective performance.
[0061] Alternatively, the inclination angle of the first bevel 412a and the inclination angle of the second bevel 412b can be the same, at this time, the reflective tooth 412 can be an isosceles triangle, so the first bevel 412a and the second bevel 412b are equal in width, at this time, the intersection of the first bevel 412a and the second bevel 412b ends at the center of the reflective tooth 412.
[0062] Of course, the reflective tooth 412 is not limited to the structure described above and can also be a "U" shaped groove, a circular arc, etc. The specific structure of the reflective tooth 412 is not limited herein.
[0063] Alternatively, the distance between the centers of two adjacent reflective teeth 412 can be in the range of 0.5mm to 1.5mm. The included angle P between the first bevel 412a and the second bevel 412b of the reflective tooth 412 can be in the range of 70° to 120°.
[0064] In the above embodiment, part of the light rays incident on the light reflecting side 4104 are easily emitted from the light reflecting side 4104 to the annular light guide 410, thereby increasing the light transmission loss. Based on this, in another alternative embodiment, the groove bottom of the annular groove 2121 can be provided with a reflective concave surface, and the reflective concave surface can be arranged opposite to the light reflecting side 4104. In this scheme, the reflective concave surface can re-reflect the light into the annular light guide 410, thereby improving the utilization rate of the light and further reducing the transmission loss of the light. In addition, the reflective concave surface can also control the reflection angle of the light, thereby being more conducive to the diffusion effect of the light spot of the light supplement assembly.
[0065] In another alternative embodiment, as shown in FIG. 3, a plurality of reflective teeth 412 can be arranged on the light reflecting side 4104, and the surface of the light transmitting annular member 220 on the side facing the annular light guide 410 can be a first surface 221. The first surface 221 can be formed with a dimming concave surface 2021, and the dimming concave surface 2021 can be arranged opposite to the light emitting side 4103. The dimming concave surface 2021 can be used to control the emission direction of the light. The groove bottom of the annular groove 2121 can be provided with a first reflective concave surface 2122, and the first reflective concave surface 2122 can be arranged opposite to the light reflecting side 4104. The first reflective concave surface 2122 can be a mirror surface.
[0066] In the specific light supplementing process, the light emitted by the first light emitting source 420 and the second light emitting source 430 enters the annular light guide member 410 through the first end surface 4101 and the second end surface 4102 respectively, is then reflected by the reflection tooth pattern 412 arranged on the reflection side 4104 and is directed to the light emitting side 4103, is emitted through the light emitting side 4103, is directed to the light adjusting concave surface 2021, is then emitted to the electronic device after the emission angle is adjusted by the light adjusting concave surface 2021. In addition, part of the light emitted from the reflection side 4104 is reflected by the first reflection concave surface 2122 and reenters the annular light emitting member, is then directed to the light emitting side 4103, and is emitted to the electronic device after the emission angle is adjusted by the light adjusting concave surface 2021.
[0067] In this scheme, the light supplementing lamp assembly 400 has good light utilization efficiency, and the light energy is emitted in a concentrated manner, so that the light supplementing effect on a small field of view and a farther distance can be better achieved. For example, the light supplementing lamp assembly 400 in this scheme is more suitable for a long-focus lens of a camera module.
[0068] In addition, the first reflection concave surface 2122 in this scheme is a mirror reflection surface, the directivity of light is stronger during mirror reflection, and the energy utilization rate is higher, so that the utilization rate of light can be further improved, thereby further reducing the light energy loss.
[0069] Optionally, the groove bottom of the annular groove 2121 can be subjected to a silver plating process, so as to form the first reflection concave surface 2122.
[0070] The radius of the light adjusting concave surface 2021 in the present application can be 1.449 mm, and of course the radius of the light adjusting concave surface 2021 can be within a range of plus or minus 0.5 mm. The radius of the first reflection concave surface 2122 can be 1.067 mm, and of course the radius of the first reflection concave surface 2122 can be within a range of plus or minus 0.2 mm.
[0071] In another optional embodiment, as shown in FIG. 5, a plurality of reflection tooth patterns 412 can be arranged on the light emitting side 4103. The groove bottom of the annular groove 2121 is provided with a second reflection concave surface 2123, and the second reflection concave surface 2123 can be arranged opposite to the reflection side 4104. The surface of the light-transmitting annular member 220 on the side facing the annular light guide member 410 is a second surface 222, and the second surface 222 can be a plane. The second reflection concave surface 2123 can be a diffuse reflection surface.
[0072] In the specific light supplementing process, the light emitted by the first light emitting source 420 and the second light emitting source 430 enters the annular light guide member 410 through the first end surface 4101 and the second end surface 4102 respectively, is then reflected by the reflection tooth pattern 412 arranged at the light exit side 4103 and shot to the light reflection side 4104, is then shot out from the light reflection side 4104, is then reflected by the second reflection concave surface 2123 and shot to the annular light guide member 410 again, and is then shot out from the light exit side 4103 and shot out to the electronic device through the light transmission annular member 220.
[0073] In this scheme, by arranging the reflection tooth pattern 412 at the light exit side 4103 of the annular light guide member 410, the light can first propagate downward, is then reflected by the second reflection concave surface 2123 after reaching the second reflection concave surface 2123, and is finally shot out. The light is refracted and reflected multiple times, and the light can be better expanded after being shot out. Therefore, the light supplementing effect on a wider field of view and a closer distance can be better achieved. For example, the light supplementing lamp assembly 400 in this scheme is more suitable for a wide-angle lens of a camera module.
[0074] In addition, the second reflection concave surface 2123 in this scheme is a diffuse reflection surface, which can completely scatter the light, thereby further improving the diffusion effect of the light spot and expanding the light supplementing range.
[0075] Optionally, the groove bottom of the annular groove 2121 can be subjected to a white coating process, so that the groove bottom forms the second reflection concave surface 2123.
[0076] The radius of the second reflection concave surface 2123 in this scheme can be the same as the radius of the first reflection concave surface 2122 described above, and details are not repeated herein.
[0077] In another optional scheme, diffusion particles are mixed in the light transmission annular member 220, thereby further strengthening the diffusion effect of the light spot and improving the soft appearance effect of the light spot.
[0078] In another optional embodiment, the camera decoration member 210 can include a substrate 211, an annular frame 212 and a lens 213. The substrate 211 can be provided with the above-mentioned opening, the annular frame 212 and the lens 213 can be stacked with the substrate 211, and the lens 213 covers the opening. The annular frame 212 can be arranged around the lens 213, and the annular frame 212 is provided with an annular groove 2121 on the side away from the substrate 211.
[0079] In the scheme, the camera decoration 210 is divided into three parts, the substrate 211 is used to carry the annular frame 212 and the lens 213, and the substrate 211 is also fixedly connected with the shell 100 of the electronic device. The substrate 211 and the lens 213 are used to cover the camera module, and the annular frame 212 is used to arrange the light supplement lamp assembly 400. At this time, the annular frame 212, the light-transmitting annular part 220 and the light supplement lamp assembly 400 can be independently assembled, so that the modular assembly of the electronic device is realized, and the assembly efficiency of the electronic device is improved.
[0080] In another optional embodiment, in the direction perpendicular to the annular light guide part 410, the cross-sectional shape of the annular light guide part 410 can be circular. At this time, the annular light guide part 410 can be a cylindrical structure. The surface of the light-emitting side 4103 and the surface of the light-reflecting side 4104 of the cylindrical structure are both arc surfaces, so that the annular light guide part 410 has better diffusion effect.
[0081] In another optional embodiment, the annular light guide part 410 can be a light guide fiber. The light guide fiber is a slender tubular structure, and the pipe wall is smoother, so that the propagation loss of light in the annular light guide part 410 is further reduced, and the light energy can uniformly fill the entire annular light guide part 410, so that the light uniformity of the light supplement lamp assembly 400 is further improved.
[0082] In the embodiment disclosed in the application, the light supplement lamp assembly 400 further includes a driving lamp holder 440, the driving lamp holder 440 is located in the annular accommodating cavity 201, the first light source 420 and the second light source 430 are electrically connected with the driving lamp holder 440, and the driving lamp holder 440 is used to realize the opening and closing of the first light source 420 and the second light source 430.
