Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art

[0002] With the development of communication technology, electronic devices such as mobile phones and tablet computers have become indispensable tools for people. When facing a wide range of electronic devices, users need to consider not only whether the functions of the electronic devices meet their needs, but also the appearance of the electronic devices is one of the important factors that influence whether consumers choose to buy them.

[0003] In order to make the appearance of electronic devices more expressive, electronic devices are provided with light source components. In the related art, the light source component includes a light emitting module and an annular light guide, both ends of the annular light guide have light incident surfaces, and the light emitted by the light emitting module enters the annular light guide through the light incident surfaces at both ends of the annular light guide, and then exits through the annular light guide.

[0004] However, in the related art, a longer area needs to be reserved at both ends of the annular light guide for light mixing. The longer the mixing area reserved at both ends of the annular light guide, the shorter the actual light effect formed by the annular light guide, thereby affecting the actual light-emitting area of ​​the electronic device, thereby causing the optical performance of the electronic device to be poor. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem of poor optical performance of the electronic device.

[0006] An embodiment of the present application provides an electronic device, including:

[0007] A mounting base, wherein the mounting base is provided with a receiving space and a light-transmitting area, and the light-transmitting area is arranged opposite to the receiving space;

[0008] A light source assembly, the light source assembly is located in the accommodating space, the light source assembly includes an annular light guide and a light-emitting module, the annular light guide includes a first light mixing section, a light guiding section, and a second light mixing section, the end face of the first end of the first light mixing section is a first light incident surface, and the second end of the first light mixing section is connected to the first end of the light guiding section; the end face of the first end of the second light mixing section is a second light incident surface, and the second end of the second light mixing section is connected to the second end of the light guiding section; the first light incident surface and the second light incident surface are both arranged opposite to the light-emitting module; the first light mixing section and the second light mixing section are both tapered structures in the direction from the first end to the second end; in the extension direction of the light guiding section, the cross-sectional areas of the light guiding sections along the extension direction perpendicular to the annular light guide are equal;

[0009] Among them, the light emitted by the light-emitting module enters the corresponding first light mixing section or the second light mixing section through the first light incident surface or the second light incident surface, enters the light guiding section from the first light mixing section and the second light mixing section, and is emitted from the light-transmitting area after passing through the light guiding section.

[0010] In the embodiment of the present application, the first light-mixing section and the second light-mixing section are tapered structures, and the cross-sectional areas of the first light-mixing section and the second light-mixing section gradually decrease along the extension direction of the first light-mixing section and the second light-mixing section toward the light-guiding section, thereby increasing the number of reflections of the light in the first light-mixing section and the second light-mixing section. Therefore, under the condition that the annular light guide in the present application and the annular light guide in the related art have the same length, since the first light-mixing section and the second light-mixing section of the annular light guide in the present application can increase the number of reflections of the light, the distance between the first light-mixing section and the second light-mixing section is shorter, thereby effectively increasing the size of the annular light guide actually forming the light effect, thereby increasing the actual light-emitting area of ​​the electronic device, and thus improving the optical performance of the electronic device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0024] The terms "first", "second", etc. 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 data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0025] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0026] Please refer to Figures 1 to 12 An embodiment of the present application discloses an electronic device, and the disclosed electronic device includes a mounting base 100 and a light source assembly 130 .

[0027] The mounting base 100 provides a mounting base for other components of the electronic device. The mounting base 100 is provided with a receiving space 101 and a light-transmitting area 1101, and the light-transmitting area 1101 is arranged opposite to the receiving space 101. Light emitted by the components installed in the receiving space 101 is emitted to the outside of the receiving space 101 through the light-transmitting area 1101. Here, it can be understood that the light-transmitting area 1101 is a part of the side wall surrounding the receiving space 101.

[0028] The light source assembly 130 is located in the accommodation space 101. The light source assembly 130 here can be a fill light for an electronic device, and of course it can also be a breathing light or an atmosphere light. The specific use scenario of the light source assembly 130 is not limited in this article. The light source assembly 130 includes an annular light guide 131 and a light-emitting module 132. The annular light guide 131 is a light transmission component. The light emitted by the light-emitting module 132 is transmitted through the annular light guide 131. The annular light guide 131 and the light-emitting module 132 are both arranged in the accommodation space 101. At this time, the light emitted by the light-emitting module 132 enters the annular light guide 131 through the light incident surfaces at both ends of the annular light guide 131, and after passing through the annular light guide 131, it is emitted from the light-transmitting area 1101 to the outside of the electronic device. The light-emitting module 132 here can be an LED (Light Emitting Diode, semiconductor light-emitting diode) lamp, a high-pressure sodium lamp, a metal halide lamp, etc. Of course, the light-emitting module 132 can also be other structures, which is not limited in this article.

[0029] Specifically, the annular light guide 131 includes a first light mixing section 1311, a light guiding section 1312, and a second light mixing section 1313. The end surface of the first end of the first light mixing section 1311 is a first light incident surface, and the second end of the first light mixing section 1311 is connected to the first end of the light guiding section 1312. The end surface of the first end of the second light mixing section 1313 is a second light incident surface, and the second end of the second light mixing section 1313 is connected to the second end of the light guiding section 1312. The first light incident surface and the second light incident surface are both arranged opposite to the light emitting surface of the light emitting module 132. At this time, the first light mixing section 1311 and the second light mixing section 1313 are located at both ends of the light guiding section 1312.

[0030] In the specific light-emitting process, the light emitted by the light-emitting module 132 enters the corresponding first light mixing section 1311 or the second light mixing section 1313 through the first light incident surface or the second light incident surface, enters the light guiding section 1312 from the first light mixing section 1311 and the second light mixing section 1313, and is emitted from the light-transmitting area 1101 after passing through the light guiding section 1312.

[0031] In the embodiment disclosed in the present application, the first light mixing section 1311 is a tapered structure in the direction from the first end to the second end. That is, in the direction from the first light mixing section 1311 to the light guide section 1312, the cross-sectional area of ​​the first light mixing section 1311 along the extension direction perpendicular to the annular light guide 131 gradually decreases. Of course, it can also be understood that the end surface of the first light mixing section 1311 facing the light-emitting module 132 is larger than the end surface of the first light mixing section 1311 connected to the light guide section 1312. At this time, the cross-sectional area of ​​the light input end of the first light mixing section 1311 is larger than the cross-sectional area of ​​the light output end of the first light mixing section 1311. Here, the light input end of the first light mixing section 1311 refers to the end where the first light input surface is located, and the light output end of the first light mixing section 1311 refers to the connection end with the light guide section 1312.

[0032] Similarly, in the direction from the first end of the second light mixing section 1313 toward the second end thereof, the second light mixing section 1313 is a tapered structure. That is, in the direction from the second light mixing section 1313 to the light guiding section 1312, the cross-sectional area of ​​the second light mixing section 1313 along the extension direction perpendicular to the annular light guiding member 131 gradually decreases. Of course, it can also be understood that the end face of the second light mixing section 1313 facing the light emitting module 132 is larger than the end face of the second light mixing section 1313 connected to the light guiding section 1312. At this time, the cross-sectional area of ​​the light input end of the second light mixing section 1313 is larger than the cross-sectional area of ​​the light output end of the second light mixing section 1313. Here, the light input end of the second light mixing section 1313 refers to the end where the second light input surface is located, and the light output end of the second light mixing section 1313 refers to the connection end with the light guiding section 1312.

[0033] In addition, in the extension direction of the light guide segment 1312, the cross-sectional areas of the light guide segment 1312 along the extension direction perpendicular to the annular light guide member 131 are equal. At this time, the sizes of the local areas of the light guide segment 1312 are the same.

[0034] In the embodiment disclosed in the present application, the first light-mixing section 1311 and the second light-mixing section 1313 are tapered structures, so the cross-sectional areas of the first light-mixing section 1311 and the second light-mixing section 1313 gradually decrease along the extension direction of the first light-mixing section 1311 and the second light-mixing section 1313 toward the light-guiding section 1312, so that the number of reflections of light in the first light-mixing section 1311 and the second light-mixing section 1313 can be increased. Therefore, under the condition that the length of the annular light guide 131 in the present application is the same as that of the annular light guide 131 in the related art, since the first light-mixing section 1311 and the second light-mixing section 1313 of the annular light guide 131 in the present application can increase the number of reflections of light, the distance between the first light-mixing section 1311 and the second light-mixing section 1313 is shorter, thereby effectively increasing the size of the annular light guide 131 that actually forms the light effect, thereby increasing the actual light-emitting area of ​​the electronic device, and thus improving the optical performance of the electronic device.

[0035] In addition, when the length of the light mixing area of ​​the annular light guide 131 in the present application and the annular light guide 131 in the related art is the same, the annular light guide 131 disclosed in the present application has better light mixing performance, so that the color and brightness distribution of the light emitted by the electronic device can be more uniform.

[0036] In addition, in the present application, the first light mixing segment 1311 and the second light mixing segment 1313 are structures in which the area of ​​the light incident surface is larger than the end surface area of ​​one end connected to the light guiding segment 1312. Therefore, the size of the light incident surface is larger, and thus as much light as possible emitted by the light emitting module 132 can enter the annular light guiding member 131, which is beneficial to improve the utilization rate of light and improve the brightness of the electronic device.

[0037] The electronic device disclosed in the present application can not only increase the actual light-emitting area of ​​the electronic device, but also effectively improve the light-emitting brightness of the electronic device.

[0038] In one solution, the light emitting module 132 may include a light emitting element. In this case, the first light incident surface and the second light incident surface are both arranged opposite to the light emitting surface of the light emitting element.

[0039] In another optional solution, the light-emitting module 132 may include a first light-emitting member 1321 and a second light-emitting member 1322, and the first light-entering surface is arranged opposite to the light-emitting surface of the first light-emitting member 1321. The second light-entering surface is arranged opposite to the light-emitting surface of the second light-emitting member 1322. The annular light-guiding member 131 disclosed in the present application is an arc-shaped strip structure, and in this case, there is a gap between the first light-entering surface and the second light-entering surface, and the gap is used to set the first light-emitting member 1321 and the second light-emitting member 1322.

[0040] The annular light guide 131 is placed in the receiving space 101 in the shape of Figure 3As shown, the annular light guide 131 can be made of a rigid light-transmitting material, such as glass. At this time, the shape of the annular light guide 131 is the same as the shape of the receiving space 101. Of course, the annular light guide 131 can be made of a flexible light-transmitting material, such as an optical fiber. At this time, when the annular light guide 131 is not placed in the receiving space 101, it can be a flexible straight strip structure. When placed in the receiving space 101, the shape of the annular light guide 131 is controlled by the shape of the receiving space 101, so that the annular light guide 131 forms an annular structure.

[0041] In the above embodiment, the first light mixing section 1311 and the second light mixing section 1313 are tapered structures, that is, the first light mixing section 1311 and the second light mixing section 1313 gradually taper from their first ends to their second ends, so the first light mixing section 1311 and the second light mixing section 1313 are overall tapered structures.

[0042] In another optional embodiment, the first light mixing section 1311 and the second light mixing section 1313 may both include a light input section 1314 and a transition section 1315, and the end of the light input section 1314 facing away from the transition section 1315 may have a first light input surface or a second light input surface. In this case, the light input section 1314 corresponding to the first light mixing section 1311 has a first light input surface, and the light input section 1314 corresponding to the second light mixing section 1313 has a second light input surface. The light input section 1314 is connected to the light guiding section 1312 through the transition section 1315, and the cross-sectional area of ​​the transition section 1315 along the extension direction perpendicular to the annular light guide 131 is smaller than the cross-sectional area of ​​the light input section 1314 along the extension direction perpendicular to the annular light guide 131. In the extension direction of the light input section 1314 toward the transition section 1315, the cross-sectional area of ​​the transition section 1315 along the extension direction perpendicular to the annular light guide 131 gradually decreases. At this time, the part with the largest cross-sectional area of ​​the transition section 1315 is the connection end with the light input section 1314 .

[0043] In this solution, the cross-sectional area of ​​the transition section 1315 gradually decreases, so the transition section 1315 is a tapered structure. At this time, the cross-sectional area of ​​the light-inlet section 1314 can be larger, so it is easy to fix the two ends of the annular light guide 131, thereby reducing the difficulty of assembling the electronic device.

[0044] In another optional solution, the cross-sectional area of ​​the light-inlet section 1314 along the extension direction perpendicular to the annular light guide 131 is the same, so the radius, area and other dimensions of the light-inlet section 1314 along its axial direction are the same. In this case, the area of ​​the light-mixing section that gradually decreases is the transition section 1315.

[0045] In another optional solution, the cross-sectional area of ​​the light-inlet section 1314 decreases along the extension direction perpendicular to the annular light guide 131, and the rate of decrease of the cross-sectional area of ​​the light-inlet section 1314 is less than the rate of decrease of the cross-sectional area of ​​the transition section 1315. At this time, the tapering rate of the light-inlet end is slower, so the area difference between the two opposite ends of the light-inlet end is smaller. The tapering rate of the transition section 1315 is faster, so the area difference between the two opposite ends of the transition section 1315 is larger. At this time, both the light-inlet section 1314 and the transition section 1315 are tapered structures, but the tapering rate of the light-inlet section 1314 is smaller, so the circumferential area is larger, so it is easier to fix. In addition, both the light-inlet section 1314 and the transition section 1315 are tapered structures, which can further improve the light mixing performance.

[0046] In the above solution, the cross-sectional shapes of the light-incoming section 1314 and the transition section 1315 can both be circular structures. At this time, the annular light guide 131 can be processed into the first light-mixing section 1311 and the second light-mixing section 1313 of the tapered structure by casting, lathe turning, etc.

[0047] In another optional embodiment, the light intake section 1314 can be a cylindrical structure. In this case, the cross-sectional shape of the light intake section 1314 along the direction perpendicular to its extension is circular. The outer surface of the transition section 1315 includes a first plane 13151 and a first curved surface 13152 connected along the circumferential direction. In the extension direction of the light intake section 1314 toward the transition section 1315, the radius of the cross section of the first curved surface 13152 along the extension direction perpendicular to the annular light guide 131 is the same, and the distance between the first plane 13151 and the first curved surface 13152 gradually decreases. The distance between the first plane 13151 and the first curved surface 13152 here can be understood as the distance between the center of the first curved surface 13152 and the vertical line of the first plane 13151. Alternatively, a first edge line extending along the extension direction of the transition section 1315 can be defined on the first curved surface 13152, and a second edge line extending along the extension direction of the transition section 1315 can be defined on the first plane 13151, and the perpendicular distance between the first edge line and the second edge line is the distance between the first plane 13151 and the first curved surface 13152.

[0048] The radius of the cross section of the first arc surface 13152 along the extending direction perpendicular to the annular light guide 131 is the same as the radius of the cross section of the light input section 1314 along the extending direction perpendicular to the annular light guide 131 .

[0049] At this time, the radius of the cross-section of the light input section 1314 is the same as the radius of the cross-section of the first curved surface 13152 of the transition section 1315. Therefore, in the specific manufacturing process, the light input section 1314 and the transition section 1315 are cylindrical structures with the same radius, and then a plane is cut obliquely on the transition section 1315. During the cutting process, the cutting depth gradually increases in the direction from the light input section 1314 to the transition section 1315, and a first plane 13151 is formed after cutting, so that the transition section 1315 forms a conical structure with a large end and a small end.

[0050] This solution can simplify the manufacturing process of the annular light guide 131, thereby reducing the manufacturing cost of the annular light guide 131. In addition, the planar structure can also further increase the light reflection performance, thereby further enhancing the brightness of the light emitted by the electronic device.

[0051] In another optional solution, the cross-sectional area of ​​the light guide segment 1312 along the extension direction perpendicular to the annular light guide 131 is the same as the area of ​​the second end face of the first light mixing segment 1311 and the second end face of the second light mixing segment 1313. It can also be understood here that the contour shape of the cross section of the light guide segment 1312 along the extension direction perpendicular to the annular light guide 131 is the same as the contour shape of the second end face of the first light mixing segment 1311 and the second end face of the second light mixing segment 1313.

[0052] In this solution, since the two ends of the light guiding segment 1312 are respectively connected to the first light mixing segment 1311 and the second light mixing segment 1313, the area of ​​the end face of the light guiding segment 1312 is the same as the area of ​​the second end face of the first light mixing segment 1311 and the second end face of the second light mixing segment 1313, so that the mixed light can fill the light guiding segment 1312, thereby avoiding the light guiding segment 1312 having different light and dark areas, thereby further improving the uniformity of the light effect.

[0053] In another optional embodiment, the light guide segment 1312 has a plurality of reflective microstructures 133 arranged at intervals along its extension direction. At this time, after the light in the first light mixing segment 1311 and the second light mixing segment 1313 enters the light guide segment 1312, it is reflected by the reflective microstructure 133 on the light guide segment 1312 and then emitted from the annular light guide 131. The reflective microstructure 133 here is for the purpose of improving the light output of the annular light guide 131. The reflective microstructure 133 is a concave structure engraved on the annular light guide 131 or a convex structure arranged on the surface of the annular light guide 131. The reflective microstructure 133 can reflect and refract light. When the light enters the light guide segment 1312, most of the light will be transmitted along the extension direction of the light guide segment 1312, so that the light is transmitted in the light guide segment 1312 without overflowing, thereby reducing the brightness of the light source assembly 130. The present application sets a reflective microstructure 133 on the light guide segment 1312 of the annular light guide 131. The reflective microstructure 133 can cause a drastic change in the reflection angle of the light incident into the light guide segment 1312, so that the light can overflow the light guide segment 1312, thereby improving the brightness of the light source assembly 130.

[0054] In one approach, if Figure 6 As shown, the reflective microstructure 133 may be a convex spherical microstructure, the spherical curvature radius of the convex spherical microstructure is in the range of 0.04 mm to 0.1 mm, and the spherical sag is in the range of 0.02 mm to 0.05 mm.

[0055] In another scheme, if Figure 7 As shown, the reflective microstructure 133 may be a convex cylindrical microstructure, the cylindrical length of the convex cylindrical microstructure may range from 0.08 mm to 0.15 mm, and the cylindrical height may range from 0.02 mm to 0.05 mm.

[0056] In another alternative, if Figure 8 As shown, the reflective microstructure 133 may be a concave truncated cone microstructure, the lower base radius of the concave truncated cone microstructure may range from 0.02 mm to 0.08 mm, the upper base radius may range from 0.04 mm to 0.16 mm, and the height may range from 0.02 mm to 0.05 mm.

[0057] In an optional solution, the light guide segment 1312 may be a cylindrical structure. In this case, the reflective microstructure 133 may be disposed on the outer side wall of the light guide segment 1312. The light guide segment 1312 may have a light emitting side facing the light transmission area 1101 and a light reflecting side facing away from the light transmission area 1101, and the reflective microstructure 133 may be disposed on the light emitting side or the light reflecting side.

[0058] For example, when the reflective microstructure 133 is disposed on the light-reflecting side, light is incident on the reflective microstructure 133, the light is reflected from the light-reflecting side to the light-emitting side by the reflective microstructure 133, and then emitted from the light-emitting side to the light-guiding segment 1312. At this time, the light can be emitted from the light-emitting side after being reflected once by the reflective microstructure 133 disposed on the light-reflecting side, thus making the transmission path of the light shorter.

[0059] For another example, the reflective microstructure 133 can be disposed on the light-emitting side. In this case, when light is incident on the reflective microstructure 133, the light is reflected from the light-emitting side to the light-reflecting side by the reflective microstructure 133, and then reflected by the light-reflecting side and the sidewall of the accommodation space 101 to the light-emitting side, and then emitted from the light-emitting side to the light-guiding segment 1312.

[0060] In another optional embodiment, the outer surface of the light guide segment 1312 may include a second plane 13121 and a second arcuate surface 13122 connected along its circumference, and the second plane 13121 is provided with a reflective microstructure 133. In this solution, the plane is more convenient for processing the reflective microstructure 133, thereby reducing the difficulty of the manufacturing process.

[0061] In a specific manufacturing process, the light-guiding material of the cylindrical structure is cut along the axial direction to cut out the second plane 13121 , and the outer surface of the remaining part of the light-guiding material of the cylindrical structure is the second arc-shaped surface 13122 .

[0062] Further, the second plane 13121 can be located on the side of the light guide segment 1312 away from the light transmission area 1101. In this case, the second plane 13121 is located on the light reflecting side of the light guide segment 1312. Therefore, the reflective microstructure 133 is located on the light reflecting side. In this solution, the light can be emitted from the light emitting side after being reflected once by the reflective microstructure 133 disposed on the light reflecting side, thereby making the transmission path of the light shorter.

[0063] In another optional embodiment, the density of the reflective microstructure 133 decreases from the middle position of the light guide segment 1312 to the two ends of the light guide segment 1312. The density of the reflective microstructure 133 here is understood as the number of reflective microstructures 133 per unit area. At this time, the closer the light guide segment 1312 is to the end position along its extension direction, the fewer the number of reflective microstructures 133, and the farther away from the end position, the more the number of reflective microstructures 133. In this scheme, the closer the light guide segment 1312 is to the end along its extension direction, the stronger its light effect is, so it is necessary to reduce the number of reflective microstructures 133 to reduce the brightness of the light output in this area, and the farther the light guide segment 1312 is from the end along its extension direction, the less light is transmitted, so it is necessary to increase the reflective microstructure 133, thereby increasing the amount of light reflection, and then improving the brightness of the light output in this area. Therefore, setting reflective microstructures 133 of different densities in different areas of the light guide segment 1312 can further improve the uniformity of light output of the electronic device.

[0064] In another optional solution, the first plane 13151 and the second plane 13121 can be arranged on the same side of the annular light guide 131. At this time, the contour shape of the cross section of the light guide segment 1312 along the extension direction perpendicular to the annular light guide 131 is the same as the contour of the second end surface of the first light mixing segment 1311 and the second light mixing segment 1313. At this time, the annular light guide 131 can be made of a cylindrical light guide substrate. Specifically, a cylindrical light guide substrate with a preset radius is selected, and then the preset lengths of the first light mixing segment 1311, the light guide segment 1312 and the second light mixing segment 1313 are divided, and then the surface of the cylindrical light guide substrate is cut, firstly, an oblique cutting is performed to cut out the first plane 13151 corresponding to the first light mixing segment 1311, and then a parallel cutting is performed to cut out the second plane 13121, and then an oblique cutting is performed to cut out the first plane 13151 corresponding to the second light mixing segment 1313. Here, the end cutting depth of the first plane 13151 is the cutting depth of the second plane 13121 .

[0065] In another optional solution, the first plane 13151 and the second plane 13121 are both located on the side of the annular light guide 131 away from the light-transmitting area 1101 .

[0066] In another optional embodiment, if Figure 3 As shown, the number of the annular light guides 131 can be at least two, namely the first annular light guide 13101 and the second annular light guide 13102; the first annular light guide 13101 and the second annular light guide 13102 can be arranged in parallel. The first annular light guide 13101 and the second annular light guide 13102 are arranged opposite to each other on the side facing the light-emitting module 132. At this time, the light guide segments 1312 of the first annular light guide 13101 and the second annular light guide 13102 can form an annular light guide structure. The corresponding first light incident surface and the second light incident surface of the first annular light guide 13101 and the second annular light guide 13102 are both arranged opposite to the light-emitting module 132.

[0067] This solution can further increase the effective light emitting surface of the electronic device, thereby further improving the light emitting performance of the electronic device. In addition, the two light guide segments 1312 of the first annular light guide 13101 and the second annular light guide 13102 can be spliced ​​to form a complete annular light ring, thereby making the light emitting effect of the electronic device more beautiful, thereby improving the appearance performance of the electronic device.

[0068] In the above embodiment, the light-emitting module 132 may include a light source driver, a first light-emitting member 1321, a second light-emitting member 1322, a third light-emitting member 1323, and a fourth light-emitting member 1324. Here, the first light-emitting member 1321, the second light-emitting member 1322, the third light-emitting member 1323, and the fourth light-emitting member 1324 are all arranged on the light source driver, and the light source driver is used to control the four light-emitting members. At this time, the first light-emitting member 1321 and the second light-emitting member 1322 correspond to the first annular light guide 13101, and the first light incident surface of the first annular light guide 13101 is arranged opposite to the light-emitting surface of the first light-emitting member 1321, and the second light incident surface of the first annular light guide 13101 is arranged opposite to the light-emitting surface of the second light-emitting member 1322. The third light-emitting component 1323 and the fourth light-emitting component 1324 correspond to the second annular light guide 13102, the first light-incident surface of the second annular light guide 13102 is arranged opposite to the light-emitting surface of the third light-emitting component 1323, and the second light-incident surface of the second annular light guide 13102 is arranged opposite to the light-emitting surface of the fourth light-emitting component 1324.

[0069] In the above embodiment, the lengths of the first annular light guide 13101 and the second annular light guide 13102 may be the same. In this case, the first annular light guide 13101 and the second annular light guide 13102 are symmetrical structures.

[0070] In another optional embodiment, the length of the first annular light guide 13101 can be a first length, and the maximum density of the reflective microstructures 133 on the first annular light guide 13101 is a first density. The length of the second annular light guide 13102 is a second length, and the maximum density of the reflective microstructures 133 on the second annular light guide 13102 is a second density. The ratio between the first length and the first density is equal to the ratio between the second length and the second density. Since the density of the reflective microstructures 133 in the middle of the light guide segment 1312 of the annular light guide 131 is the largest, the maximum density here can be the density of the reflective microstructures 133 in the middle of the light guide segment 1312.

[0071] In this solution, when the lengths of the first annular light guide 13101 and the second annular light guide 13102 are not equal, the density distribution of the reflective microstructures 133 of the first annular light guide 13101 and the second annular light guide 13102 also needs to be designed to be unequal. According to the principle of energy conservation, the relationship between the total length L of the annular light guide 131 and the maximum density ρ of the microstructure needs to satisfy L 1 / ρ 1 =L 2 / ρ 2 , where L1 and L2 are the lengths of the first annular light guide 13101 and the second annular light guide 13102, respectively, 1 and ρ 2They are the maximum density of the reflective microstructure 133 of the first annular light guide 13101 and the second annular light guide 13102, respectively. It can be understood here that when the length of the annular light guide 131 is longer, it is necessary to increase the density of the reflective microstructure 133, thereby increasing the light output brightness of the annular light guide 131. When the length of the annular light guide 131 is shorter, it is necessary to reduce the density of the reflective microstructure 133, thereby reducing the light output brightness of the annular light guide 131. Therefore, the light output brightness between the first annular light guide 13101 and the second annular light guide 13102 is similar. Therefore, even when the lengths of the first annular light guide 13101 and the second annular light guide 13102 are not equal, the effect of uniform light emission in the entire annular area can be achieved, thereby further improving the light output uniformity of the electronic device.

[0072] In the above embodiment, when the radius of curvature of the light guide segment 1312 is small, light can easily escape from the light guide segment 1312, thereby forming local brightness, thus causing uneven brightness and color of the light effect of the electronic device. The radius of curvature of the light guide segment 1312 here refers to the degree of curvature of the light guide segment 1312.

[0073] Based on this, in another optional solution, the radius of the first light incident surface and the radius of the second light incident surface can both be the first size. The curvature radius of the light guide segment 1312 is the second size. Figure 3 At this time, the second size may be greater than or equal to 4 times the first size and less than or equal to 6 times the first size.

[0074] This solution can ensure that light does not escape from the bend, thereby avoiding the formation of local brightness, thereby further improving the brightness and color uniformity of the light effect of the electronic device.

[0075] In another optional embodiment, a first reflective surface 121 is provided in the accommodating space 101, and the first reflective surface 121 can be arranged opposite to the light-transmitting area 1101. The first reflective surface 121 can be arranged around the annular light guide 131. The light emitted from the light-transmitting area 1101 after being emitted through the light-guiding section 1312 and reflected by the first reflective surface 121 can be the first viewing angle light 141. The light emitted from the light-guiding section 1312 and directly emitted from the light-transmitting area 1101 without being reflected by the first reflective surface 121 can be the second viewing angle light 142.

[0076] In this solution, the light emitted by the light-emitting module 132 enters the annular light guide 131 for light guidance. Among the light emitted by the annular light guide 131, a part is reflected by the first reflection surface 121 and then emitted from the light-transmitting area 1101, while the other part is directly emitted from the light-transmitting area 1101 without being reflected by the first reflection surface 121. At this time, the light emitted by the annular light guide 131 can form two transmission paths. Here, the light reflected by the first reflection surface 121 has a lower brightness due to the increase in the number of reflections; the light directly emitted from the light-transmitting area 1101 without being reflected by the first reflection surface 121 has a higher brightness. Therefore, the brightness of the first viewing angle light 141 and the second viewing angle light 142 is different. Therefore, different optical effects can be observed at different viewing angles, thereby improving the optical performance of the electronic device.

[0077] In another optional embodiment, the mounting base 100 may include a cover plate 110 and a decorative ring 120, and the cover plate 110 may have a light-transmitting area 1101. The decorative ring 120 and the cover plate 110 may enclose a receiving space 101. The inner surface of the decorative ring 120 may be provided with a first reflecting surface 121. In this solution, the light source assembly 130 is arranged on the decorative ring 120, so that the light source assembly 130 is separated from the internal space of the electronic device, thereby optimizing the layout of the electronic device.

[0078] In the above embodiment, the mounting base 100 can be a camera module decoration member, and in this case, the mounting base 100 is used to decorate the camera module. In this case, the annular area surrounded by the annular light guide 131 can be opposite to the lens of the camera module, so that external light enters the camera module through the annular area surrounded by the light-transmitting area 1101 and the annular light guide 131, thereby realizing the camera function of the camera module.

[0079] The mounting base 100 may also be a device housing of an electronic device, wherein the light-transmitting area 1101 may be a light-transmitting area opened on the device housing, and the accommodating space 101 is the internal space of the device housing.

[0080] In another optional solution, the light source assembly 130 may further include a light homogenizing cover 134, the light homogenizing cover 134 may be located in the accommodating space 101, and the first reflecting surface 121 may be arranged around the light homogenizing cover 134. The annular light guide 131 may be located in the light homogenizing cover 134. Among them, the light emitted from the light-transmitting area 1101 after being emitted through the light guide segment 1312 and passing through the light homogenizing cover 134 and the first reflecting surface 121 in sequence is the first viewing angle light 141. The light emitted from the light guide segment 1312 and passing through the light homogenizing cover 134 and directly emitting from the light-transmitting area 1101 without being reflected by the first reflecting surface 121 is the second viewing angle light 142.

[0081] In this solution, the light homogenizing cover 134 can shield the uneven hot spots from the reflective microstructure 133 on the annular light guide 131, thereby further improving the light uniformity of the electronic device.

[0082] Optionally, the light homogenizing cover 134 is made of transparent plastic or transparent glass. To achieve the light homogenizing effect of the light homogenizing cover 134, all surfaces of the light homogenizing cover 134 may be provided with sunrays. Alternatively, scattering particles are added to the transparent material to achieve light homogenization, and the particle size of the scattering particles is 1 μm-10 μm.

[0083] The light homogenizing cover 134 in the above embodiment may have corresponding holes for the camera module to receive external light.

[0084] In the above embodiment, the light homogenizer 134 can wrap the light guide segment 1312 as a whole. At this time, part of the light passing through the outer wall of the light homogenizer 134 is reflected by the first reflection surface 121 to form a first viewing angle light 141. Another part of the light passing through the top and outer wall of the light homogenizer 134 is not reflected by the first reflection surface 121 to form a second viewing angle light 142. In this solution, the top of the light homogenizer 134 can also emit light.

[0085] In another optional embodiment, a receiving groove 1341 is provided on the side of the light homogenizing cover 134 facing the cover plate 110, and the annular light guide 131 can be located in the receiving groove 1341. The cover plate 110 may include a light shielding layer 112 and a light-transmitting member 111, and the light-transmitting member 111 can enclose the above-mentioned receiving space 101 with the decorative ring 120. The light-transmitting member 111 here can be a lens. The light-transmitting member 111 has a first area and a second area, and the first area can be arranged around the second area, and the first area is the above-mentioned light-transmitting area 1101. The second area is provided with a light shielding layer 112, and the light shielding layer 112 covers the notch of the receiving groove 1341.

[0086] At this time, light is emitted from the outer wall of the light homogenizing cover 134, that is, the light passes through the outer wall of the receiving groove 1341. No light is emitted from the top of the light homogenizing cover 134.

[0087] In this solution, no light is emitted from the top of the light homogenizing cover 134, thus avoiding the influence on the camera module. In addition, the light homogenizing cover 134 is set as an open structure, which is also convenient for manufacturing the light homogenizing cover 134, thereby reducing the manufacturing cost of the electronic device.

[0088] In the scheme where the number of the annular light guides 131 is two, the accommodating groove 1341 may include a first arc segment 1341a, a second arc segment 1341b, a first connecting segment 1341c, and a second connecting segment 1341d. The first connecting segment 1341c and the second connecting segment 1341d are located between the first arc segment 1341a and the second arc segment 1341b. The first connecting segment 1341c here can be used to accommodate the first light mixing segment 1311 of the first annular light guide 13101 and the second annular light guide 13102 mentioned above. The second connecting segment 1341d can be used to accommodate the second light mixing segment 1313 of the first annular light guide 13101 and the second annular light guide 13102 mentioned above. The first arc segment 1341a can be used to accommodate the light guiding segment 1312 of the first annular light guide 13101. The second arc segment 1341b can be used to accommodate the light guiding segment 1312 of the second annular light guide 13102.

[0089] In the above solution, the light shielding layer 112 also needs to have corresponding openings to allow external light to enter the camera module through the second area and the openings.

[0090] In another optional solution, the light source assembly 130 may further include a reflective film 135, which is disposed at the bottom of the receiving groove 1341. The reflective film 135 may have a second reflective surface, and the second reflective surface and the annular light guide 131 may be disposed opposite to each other. In this solution, the reflective film 135 can reflect the light overflowing from the annular light guide 131 again into the annular light guide 131 or the light homogenizing cover 134, thereby improving the utilization rate of light energy, and further improving the light output brightness of the electronic device.

[0091] Optionally, the reflective film 135 is made of PET (polyethylene terephthalate), the surface color may be white, and the reflectivity is ≥80%.

[0092] The light shielding layer 112 and the inner side wall of the receiving groove 1341 may also be provided with a reflective structure, which is not limited herein.

[0093] In another optional embodiment, in the extension direction of the light-transmitting area 1101 toward the light source assembly 130, the first reflective surface 121 is tilted toward the center direction of the accommodating space 101. At this time, in the extension direction of the light area toward the light source assembly 130, the cross-sectional area of ​​the first reflective surface 121 is reduced. It can also be understood that the first reflective surface 121 is tilted to the plane where the light-transmitting area 1101 is located. This solution can achieve high-efficiency reflection, thereby further improving the light efficiency.

[0094] Optionally, the angle between the plane where the light-transmitting area 1101 is located and the first reflective surface 121 is in the range of 15° to 25°. Figure 2 As shown, the angle between the first reflective surface 121 and the plane where the light-transmitting area 1101 is located is α, and the angle α can be between 15° and 25°. This solution can further improve the light reflection efficiency.

[0095] In another optional solution, the first reflective surface 121 may be provided with a plurality of reflective protrusions 1211, and the plurality of reflective protrusions 1211 may be arranged at intervals along the circumference of the first reflective surface 121, and a reflective gap 1212 may be formed between any two adjacent reflective protrusions 1211. In this solution, when incident light from the same direction is incident on different positions of the first reflective surface 121, due to the different reflective efficiencies of the reflective protrusions 1211 and the reflective gaps, the direction and brightness of the emitted light differ greatly (e.g., Fig.11 The emitting direction A and the emitting direction B shown in the figure) enable the electronic device to achieve a light and dark alternating reflected light effect, thereby further improving the optical performance of the electronic device.

[0096] Optionally, the first reflective surface 121 may be a straight surface, a circular arc surface, an aspherical surface, etc. Of course, the first reflective surface 121 may also be other surface shapes which will not be described in detail herein.

[0097] The electronic device disclosed in the embodiments of the present application may be a smart phone, a tablet computer, an e-book reader, a wearable device (such as a smart watch), an electronic game console, and the like, and the embodiments of the present application do not limit the specific types of electronic devices. The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods, which are merely illustrative and not restrictive. Under the guidance of the present application, a person of ordinary skill in the art can also make many forms without departing from the scope of protection of the purpose of the present application and the claims, all of which fall within the protection of the present application.
