[0001] This application belongs to the field of communication technologies, and particularly relates to an electronic device. Background Art

[0002] With the continuous improvement of the imaging functions of electronic devices such as mobile phones, the demand for taking pictures with electronic devices is also increasing, and various shooting scenarios emerge in an endless stream. For scenarios such as low-light environments and night shooting, it is difficult to take clear photos, and it is also very difficult to have a good experience in video recording or live broadcast scenarios. Therefore, a fill light is provided on the electronic device, and the fill light can perform fill light operations on shooting. In addition, the fill light can also be used as a flashlight for lighting operations.

[0003] In related technologies, in order to achieve a better fill light effect of an electronic device, the light spot of the fill light of the electronic device needs to cover the field of view angle range of the camera. Therefore, the fill light of the electronic device needs to be designed with a larger illumination range to meet the fill light requirements of the electronic device.

[0004] However, since the illumination range of the fill light of the electronic device is relatively large, it will inevitably affect the illumination intensity of the fill light. Therefore, when the fill light is used as a flashlight, the illumination brightness is low and the illumination distance is short. Therefore, the illumination performance of the electronic device in related technologies is poor. Summary of the Invention

[0005] The purpose of the embodiments of this application is to provide an electronic device, which can solve the technical problem of poor illumination performance of the electronic device.

It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0012] Next, the electronic device provided in the embodiments of the present application will be described in detail with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0013] Please refer to Figures 1 to 10 , the embodiments of the present application disclose an electronic device, and the disclosed electronic device includes a device main body 200 and a lighting component 100.

[0014] The device main body 200 is the main component of the electronic device. The device main body 200 includes, but is not limited to, a housing 210, a circuit board, a display module, and other functional components. The device main body 200 is provided with a receiving cavity and a first through hole 2201 communicating with the receiving cavity. The first through hole 2201 here penetrates the device main body 200, so that the receiving cavity inside the device main body 200 communicates with the external environment. The receiving cavity is used to install the components of the electronic device. For example, components such as a circuit board, a camera module, and a fill light are installed in the receiving cavity. In one solution, the housing 210 of the device main body 200 is provided with a receiving cavity, and the first through hole 2201 is provided on the housing 210. The first through hole 2201 here can be provided on the front shell of the housing 210, or can be provided on the back cover of the housing 210, and the back cover here is the battery cover. Alternatively, in another alternative solution, the housing 210 of the device main body 200 and the display module enclose a receiving cavity, and the first through hole 2201 can be provided on the housing 210, or the gap between the housing 210 and the display module forms the first through hole 2201.

[0015] The lighting component 100 includes a light-emitting light source 110 and a light distribution member 120. At least part of the light distribution member 120 is located in the first through hole 2201, and the light-emitting light source 110 is located in the receiving cavity. At this time, the light-emitting light source 110 is electrically connected to the circuit board of the electronic device, so as to realize the power supply and control of the light-emitting light source 110.

[0016] The light distribution member 120 has a first surface 121 and a second surface 122 arranged opposite to each other. At least part of the first surface 121 is a light-emitting surface 1211, that is to say, the first surface 121 here is the light-emitting surface 1211, or a partial area of the first surface 121 emits light, so a partial area of the first surface 121 serves as the light-emitting surface 1211. Similarly, the second surface 122 can be a light-incident surface 1221, or a partial area of the second surface 122 admits light, so a partial area of the second surface 122 serves as the light-incident surface 1221. Since the light distribution member 120 needs to conduct light, the light distribution member 120 can be made of a light-conducting material such as transparent plastic or transparent glass.

[0017] The light-emitting light source 110 is located on the side where the second surface 122 of the light distribution member 120 is located, and the light-emitting light source 110 is arranged opposite to the light-incident surface 1221. At this time, the light emitted by the light-emitting light source 110 enters the light distribution member 120 through the light-incident surface 1221, and then is emitted through the light-emitting surface 1211. The light-emitting light source 110 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 light source 110 can also have other structures, which are not limited in this article.

[0018] The light incident surface 1221 includes a first light incident structure 1221a and a second light incident structure 1221b. The second light incident structure 1221b is disposed around the first light incident structure 1221a. Both the first light incident structure 1221a and the second light incident structure 1221b are rotationally symmetric about the central optical axis W of the light emitting source 110. Here, the central optical axis W refers to the optical axis at the central position of the light emitting source 110 or the physical center line of the light emitting source 110.

[0019] Specifically, the first light incident structure 1221a is an arc-shaped convex surface, and the arc-shaped convex surface is used to converge the light emitted by the light emitting source 110. At this time, the arc-shaped convex surface has a relatively precise light angle contraction effect on the small-angle light of the light emitting source 110, thereby realizing the collimation effect of the light, and further improving the light focusing performance, and thus enhancing the illumination light effect. The small-angle light of the light emitting source 110 here mainly refers to the light emitted from the central position of the light emitting surface 111 close to the light emitting source 110.

[0020] The second light incident structure 1221b includes a plurality of annular teeth 1221b1, and the plurality of annular teeth 1221b1 are continuously arranged in a direction away from the first light incident structure 1221a. That is to say, the plurality of annular teeth 1221b1 are continuously arranged in a direction from the center of the light incident surface 1221 to the edge of the light incident surface 1221. The plurality of annular teeth 1221b1 are used to diffuse the light emitted by the light emitting source 110. Since each annular tooth 1221b1 has two opposite side walls, first, the light enters through one of the side walls, and this side wall can realize the refraction of the incident light, and the refracted light can be reflected by the other side wall. Therefore, the radiation angle of the light can be increased through one refraction and one reflection, which is beneficial to the diffusion of the light spot, and thus the illumination range is increased. Here, the second light incident structure 1221b is located at the edge of the light incident surface 1221, so the second light incident structure 1221b is used to diffuse the large-angle light of the light emitting source 110. The large-angle light of the light emitting source 110 here can be understood as the light emitted from the edge position of the light emitting surface 111 close to the light emitting source 110.

[0021] In the embodiment disclosed in the present application, the light distribution member 120 has two light distribution regions. The arc-shaped convex surface provided at the center can collimate and focus the light, while the annular teeth 1221b1 at the edge can diffuse the light spot, so as to better realize a light spot with high illumination brightness and a large range, and thus can realize a super-bright illumination effect, and further improve the illumination performance of the electronic device.

[0022] In one solution, in the direction of the central optical axis W of the light-emitting light source 110, the orthographic projection contour of the light-emitting surface 111 of the light-emitting light source 110 can be rectangular. For example, the orthographic projection contour of the light-emitting surface 111 of the light-emitting light source 110 can be a square or a rectangle. That is to say, the light-emitting surface 111 of the light-emitting light source 110 is a rectangular structure. When the light-emitting surface 111 of the light-emitting light source 110 is rectangular, the light distribution member 120 can focus the light emitted from the middle area of the rectangular light-emitting surface 111 through the first light-incident structure 1221a, thereby improving the spot brightness. At the same time, the light distribution member 120 can diffuse the light emitted from the edge area of the rectangular light-emitting surface 111 through the second light-incident structure 1221b, thereby forming a circular spot, and further achieving a better lighting effect. In the electronic device disclosed in the present application, the light distribution member 120 can not only improve the brightness of the spot, but also diffuse the light emitted from the rectangular light-emitting surface 1211 into a circular spot. Therefore, it is more conducive to the optimization of the spot and meets the usage habits of consumers for the circular spot of the flashlight. Therefore, the light-emitting light source 110 in the present application can adopt a large-size square LED, which is beneficial to further improving the lighting effect of the electronic device. In addition, compared with the large-size circular LED, the large-size square LED has a simple manufacturing process and a lower cost, so it is beneficial to reduce the cost of the electronic device.

[0023] In order not to affect the overall thickness of the electronic device, in another alternative solution, the thickness of the light-emitting light source 110 can be less than or equal to 0.7 mm. At this time, the thickness of the light-emitting light source 110 is small, so it is beneficial to reduce the overall thickness of the electronic device, thereby realizing the development of the electronic device towards thinness and lightness.

[0024] In another alternative embodiment, in the direction of the central optical axis W of the light-emitting light source 110, the orthographic projection contour of the light-emitting surface 111 of the light-emitting light source 110 is rectangular, and the radius of the orthographic projection contour of the first light-incident structure 1221a is the first dimension. Here, the first dimension can be understood as the distance between any point on the edge of the first light-incident structure 1221a and the central optical axis W. Half of the long side length of the orthographic projection contour of the light-emitting surface 111 of the light-emitting light source 110 is the second dimension, and the first dimension is greater than the second dimension. When the entire surface on one side of the light-emitting light source 110 is the light-emitting surface 111, the long side dimension of the light-emitting light source 110 is the long side dimension of the light-emitting surface 111. When only a partial area of the surface on one side of the light-emitting light source 110 is the light-emitting surface 111, the long side dimension of the light-emitting light source 110 is greater than the long side dimension of the light-emitting surface 111. Since the encapsulation of the light-emitting light source 110 requires a certain size, the size of the light-emitting surface 111 here can also include the encapsulation size at the edge of the light-emitting surface 111.

[0025] In this solution, the light-emitting surface 111 of the light-emitting light source 110 does not exceed the contour range of the first light-incident structure 1221a or the dimension exceeding the contour range of the first light-incident structure 1221a is small. Therefore, the vast majority of the light rays emitted by the light-emitting light source 110 can be collimated by the first light-incident structure 1221a, thereby further improving the brightness of the light spot formed by the lighting component 100, and further improving the lighting performance of the electronic device. In addition, the light-emitting surface 111 of the light-emitting light source 110 does not exceed the contour range of the first light-incident structure 1221a or the dimension exceeding the contour range of the first light-incident structure 1221a is small, which also makes the light-emitting surface 111 not be cut by the plurality of annular teeth 1221b1, so that it is not easy for the user to see the light-emitting light source 110 from a large angle, thus ensuring the delicate appearance of the lighting component 100, and therefore making the electronic device have good appearance performance.

[0026] Further, the difference between the first dimension and the second dimension is greater than or equal to 0.1 mm. At this time, a distance greater than or equal to 0.1 mm is reserved between both sides of the light-emitting surface 111 and the contour of the first light-incident structure 1221a, thereby further ensuring that the light-emitting surface 111 does not exceed the contour range of the first light-incident structure 1221a, thereby further improving the brightness of the light spot formed by the lighting component 100, and further improving the lighting performance of the electronic device. At the same time, the appearance performance of the electronic device can also be further improved.

[0027] Optionally, the first dimension can be 0.9 mm and the second dimension can be 0.8 mm. At this time, it can not only ensure that the area of the first light-incident structure 1221a is large, so as to collect more light rays to improve the brightness of the lighting component 100, but also has good appearance performance. Of course, the first dimension and the second dimension can also be other values, which are not limited in this article.

[0028] In another optional embodiment, in the direction of the central optical axis W of the light-emitting light source 110, the orthographic projection contour of the light-emitting surface 111 of the light-emitting light source 110 is located within the orthographic projection contour of the first light-incident structure 1221a. Here, it can be understood that the maximum projection contour of the light-emitting surface 111 is an inscribed rectangle of the orthographic projection contour of the first light-incident structure 1221a. This solution further ensures that the light-emitting surface 111 does not exceed the contour range of the first light-incident structure 1221a, thereby further improving the brightness of the light spot formed by the lighting component 100 and further improving the lighting performance of the electronic device. At the same time, the appearance performance of the electronic device can also be further improved.

[0029] Of course, the light-emitting surface 111 in this application is not limited to a rectangle, and can also be other shapes, such as a circle, an ellipse, etc.

[0030] In another alternative embodiment, in the direction from the first light-incident structure 1221a to the second light-incident structure 1221b, the distance between the tooth crest of the annular tooth 1221b1 and the light-emitting surface 1211 gradually increases. The direction from the first light-incident structure 1221a to the second light-incident structure 1221b here can be understood as the direction from the center of the light-incident surface 1221 to the edge of the light-incident surface 1221. At this time, the light-emitting surface 1211 serves as a reference surface. Therefore, the fact that the distance between the tooth crest of the annular tooth 1221b1 and the light-emitting surface 1211 gradually increases can be understood as the tooth crest of the outer annular tooth 1221b1 protruding from the tooth crest of the inner annular tooth 1221b1. In this solution, since the tooth crest of the outer annular tooth 1221b1 protrudes from the tooth crest of the inner annular tooth 1221b1, the outer annular tooth 1221b1 is prevented from being blocked by the inner annular tooth 1221b1. Therefore, the utilization rate of light can be further improved, thereby improving the optical performance.

[0031] In one solution, the number of the multiple annular teeth 1221b1 can be three. In the direction from the center of the light-incident surface 1221 to the edge of the light-incident surface 1221, the three annular teeth 1221b1 are respectively a first annular tooth, a second annular tooth, and a third annular tooth. Here, the first annular tooth is the annular tooth 1221b1 adjacent to the first light-incident structure 1221a. The distance between the tooth crest of the first annular tooth and the light-emitting surface 1211 is a first distance, and the first distance is as shown by H1 in Figure 9 . The distance between the tooth crest of the second annular tooth and the light-emitting surface 1211 is a second distance, and the second distance is as shown by H2 in Figure 9 . The distance between the tooth crest of the third annular tooth and the light-emitting surface 1211 is a third distance, and the third distance is as shown by H3 in Figure 8 . At this time, the first distance is 0.07 mm smaller than the second distance, and the second distance is 0.1 mm smaller than the third distance. Of course, the differences between the first distance and the second distance and between the second distance and the third distance can also be other values, which are not limited in this article.

[0032] Furthermore, the tooth width of the multiple annular teeth 1221b1 can be controlled within the range of 0.45 mm to 0.55 mm. The tooth width of the annular tooth 1221b1 here can be understood as the distance between the tooth bottoms on the opposite sides of each annular tooth 1221b1. In the above solution, the tooth bottom on one side of the first annular tooth and the edge of the first light-incident structure form a first groove, and the tooth bottom of the first annular tooth and the tooth bottom of the second annular tooth form a second groove. At this time, the distance between the bottom of the first groove and the bottom of the second groove is the tooth width of the first annular tooth. The tooth width of the first annular tooth is as shown by A1 in Figure 9 . Similarly, the tooth widths of the second annular tooth and the third annular tooth can be obtained. The tooth width of the second annular tooth is as shown by A2 in Figure 9 , and the tooth width of the third annular tooth is as shown by A3 in Figure 9As shown in A3 in []. At this time, the tooth width of each annular tooth 1221b1 can be controlled within the range of 0.45 mm to 0.55 mm, so that while controlling the light, visual alignment can be achieved in terms of appearance, which is beneficial to improving the appearance delicacy of the electronic device.

[0033] In another alternative solution, the distance between the first light-incident structure 1221a and the light-emitting surface 111 of the light-emitting light source 110 can be greater than or equal to 0.7 mm. This solution can strive for a larger range of light intensity for the light incident on the light distribution member 120, which is beneficial to further improving the lighting performance of the electronic device.

[0034] In another alternative embodiment, the light distribution member 120 further has a texture area 1222, and the texture area 1222 and the light-incident surface 1221 can be provided on the same side of the light distribution member 120. At this time, the above-mentioned second surface 122 can include the texture area 1222 and the light-incident surface 1221. The texture area 1222 can be arranged around the second light-incident structure 1221b, and the texture area 1222 can be arranged opposite to the light-emitting surface 1211. The texture area 1222 can be provided with a texture structure 123. In this solution, external light can irradiate the texture structure 123 through the light-emitting surface 1211, so as to illuminate the texture structure 123. Therefore, it can be clearly observed in appearance that the texture structure 123 protrudes outward relative to the light-incident surface 1221 and the light-emitting surface 1211, thereby making the overall appearance effect of the electronic device more three-dimensional and diverse, and thus improving the appearance performance of the electronic device.

[0035] In an alternative solution, the texture structure 123 includes a plurality of strip-shaped grooves 1231. The plurality of strip-shaped grooves 1231 can be continuously arranged along the circumferential direction of the texture area 1222, and each strip-shaped groove 1231 can extend along the radial direction of the light-incident surface 1221. It can be understood here that the central axis of each strip-shaped groove 1231 passes through the center of the light-incident surface 1221. At this time, each strip-shaped groove 1231 can be understood as a spoke. Therefore, the plurality of strip-shaped grooves 1231 can form a radial shape radiating from the center of the light-incident surface 1221 to its edge.

[0036] In this solution, the light-emitting surface 1211 is a plane as a whole, so it forms a base plane. A plurality of strip-shaped grooves 1231 are superimposed on the light-emitting surface 1211, so a layer of radial stripe-like texture is formed on the base plane, which enriches the appearance beauty of the lighting component 100, makes the appearance performance of the lighting component 100 more diverse, and thus improves the appearance beauty of the electronic device.

[0037] Further, the strip-shaped groove 1231 may include a first side surface 1231a and a second side surface 1231b that are oppositely arranged. The first side surface 1231a and the second side surface 1231b intersect to form a first intersection line 1241. Here, the first intersection line 1241 can be understood as the bottom position of the strip-shaped groove 1231. In the direction of the first light-incident structure 1221a towards the texture structure 123, the distance between the first intersection line 1241 and the light-emitting surface 1211 gradually increases. At this time, since the first intersection line 1241 is the bottom of the strip-shaped groove 1231, the distance between the first intersection line 1241 and the light-emitting surface 1211 is the distance between the bottom of the strip-shaped groove 1231 and the light-emitting surface 1211. In the direction of the first light-incident structure 1221a towards the texture structure 123, the distance between the bottom of the strip-shaped groove 1231 and the light-emitting surface 1211 gradually increases, that is, the depth of the strip-shaped groove 1231 gradually becomes smaller, and the groove depth decreases. In this solution, in the direction of the first light-incident structure 1221a towards the texture structure 123, the groove depth of the strip-shaped groove 1231 gradually decreases. Therefore, in the extending direction of the strip-shaped groove 1231, the reflection angle of the strip-shaped groove 1231 on the light changes, so that the user can see the texture with light and dark changes, which is beneficial to further improving the appearance performance of the electronic device.

[0038] In another alternative solution, as Figure 10 shown, on the side of the first side surface 1231a away from the first intersection line 1241, there is a first edge line 1242, and on the side of the second side surface 1231b away from the first intersection line 1241, there is a second edge line 1243. Among them, the extension line of the first intersection line 1241 passes through the center of the light-incident surface 1221, which can be understood as the center of the light-incident surface 1221. The first edge line 1242 and the second edge line 1243 are rotationally symmetric about the first intersection line 1241. In this solution, the strip-shaped groove 1231 is symmetric about the intersection line of its bottom, so that the reflection efficiency of the strip-shaped groove 1231 at the same circumferential position is consistent, while the reflection efficiency in its extending direction is different. Therefore, while increasing the diversity of the texture structure 123, the texture structure 123 is made more regular, avoiding the user seeing an abrupt feeling in the texture structure 123, and thus further improving the appearance performance of the electronic device.

[0039] In the above solution, since each strip-shaped groove 1231 is rotationally symmetric about its intersection line, multiple strip-shaped grooves 1231 can be rotationally symmetric about the central optical axis W. At this time, the texture structure 123 is formed by multiple rotationally symmetric strip-shaped grooves 1231.

[0040] In an alternative solution, the included angle between the first side line 1242 and the second side line 1243 can be 9°. That is to say, the included angles between the first intersecting line 1241 and the first side line 1242 and the second side line 1243 are both 4.5°. Therefore, the first intersecting line 1241 can form the first side line 1242 by rotating 4.5° along the first direction, and the first intersecting line 1241 can form the second side line 1243 by rotating 4.5° along the second direction opposite to the first direction. Of course, the included angle between the first side line 1242 and the second side line 1243 can also be other angles, which are not limited in this article. In this application, the strip-shaped groove 1231 can be formed according to the included angles between the first intersecting line 1241 and the first side line 1242 and the second side line 1243, as well as the maximum distance and the minimum distance between the first intersecting line 1241 and the light-emitting surface 1211.

[0041] In the above solution, due to the focusing effect of the light-incident surface 1221 on the light-emitting light source 110, the defects on the light-emitting surface 111 of the light-emitting light source 110 will also be magnified. For example, the yellow spots and explosion points on the light-emitting surface 111 will also be magnified, thus affecting the optical performance. In an alternative solution, the light-emitting surface 1211 can have a first light-emitting area 1211a and a second light-emitting area 1211b. The second light-emitting area 1211b can be arranged to surround the first light-emitting area 1211a. The light transmittance of the first light-emitting area 1211a is less than that of the second light-emitting area 1211b. The first light-emitting area 1211a is arranged opposite to the light-incident surface 1221, and the second light-emitting area 1211b is arranged opposite to the texture area 1222. In this solution, reducing the light transmittance of the area of the light-emitting surface 1211 opposite to the light-incident surface 1221 can weaken the light spot defects, thus being beneficial to the optical performance of the lighting component 100. In addition, the light transmittance of the area of the texture structure 123 opposite to the light-emitting surface 1211 is relatively high, so it will not affect the user's view of the texture structure 123, and thus maintain the delicate appearance of the electronic device.

[0042] Optionally, the first light-emitting area 1211a can be subjected to a light matte texture, while the second light-emitting area 1211b can be untreated or subjected to a high-gloss mirror finish. Of course, the specific light transmittance of the first light-emitting area 1211a can be flexibly selected according to the process requirements.

[0043] In the above solution, the orthographic projection contour of the first light-emitting area 1211a can coincide with the orthographic projection contour of the light-incident surface 1221. That is to say, the area of the first light-emitting area 1211a is the same as the area of the light-incident surface 1221. For example, when the diameter of the light-incident surface 1221 is 5.1 mm, the diameter of the first light-emitting area 1211a can also be set to 5.1 mm. Of course, the diameter of the first light-emitting area 1211a can also be other sizes, which are not limited in this article.

[0044] In another alternative solution, the difference between the outer diameter of the texture area 1222 and the radius of the light incident surface 1221 can be a first value, such as the Figure 6 shown as B2 in Figure 6 shown as B1 in

[0045] The radius of the light incident surface 1221 here is the inner diameter of the texture area 1222. The ratio range of the first value to the second value can be greater than or equal to 0.4 and less than or equal to 0.6. At this time, not only does the light distribution member 120 have a larger light incident surface 1221, but also the light distribution member 120 has a larger texture area 1222, so as to achieve the matching of the light incident surface 1221 and the texture area 1222. Furthermore, the lighting assembly 100 not only has a better lighting effect but also has a better appearance effect, so that the lighting assembly 100 improves both the optical performance and the appearance performance at the same time.

[0046] In another alternative embodiment, the light distribution member 120 may further have a flat area 1223, and the flat area 1223 may be disposed around the texture area 1222. The flat area 1223 here is a partial area of the second surface 122. The second surface 122 may include the flat area 1223, the texture area 1222, and the light incident surface 1221. The flat area 1223 may be provided with an anti-fooling structure and a positioning structure, and the positioning structure and the anti-fooling structure are respectively matched with the device main body 200. This solution can improve the assembly accuracy of the electronic device.

[0047] Optionally, as Figure 8 shown, the flat area 1223 may be provided with structures such as through holes or notches for anti-fooling or positioning. Or, in another alternative solution, the outer edge of the flat area 1223 may be set as a special-shaped structure. For example, as Figure 8 shown, the outer edge of the flat area 1223 may be formed by multiple arc-shaped structures and linear structures. Of course, the anti-fooling structure and the positioning structure may also be other structures, which are not limited in this article.

[0048] In another alternative embodiment, the device main body 200 may include a housing 210 and a decorative member 220. The housing 210 may be provided with a receiving cavity, the decorative member 220 may be disposed on the housing 210, the decorative member 220 may be provided with a first through hole 2201, and the light distribution member 120 may be bonded to the surface of the decorative member 220 facing the receiving cavity. At this time, the light distribution member 120 can be bonded to the decorative member 220 through a bonding structure such as glue or double-sided tape.

[0049] In this solution, the lighting assembly 100 is installed on the decorative member 220, thereby reducing the space occupied by the lighting assembly 100 on the housing 210, which is beneficial for optimizing the layout structure of the electronic device.

[0050] In the above solution, the light distribution component 120 is bonded to the decorative component 220, and the light source 110 can be arranged on the main board or sub-board of the electronic device.

[0051] In order to prevent the portion of the decorative member 220 protruding from the outer surface of the housing 210 from blocking the light emitted by the lighting assembly 100, in another optional solution, the inclination angle of the line between the highest point of the decorative member 220 protruding from the outer surface of the housing 210 and any point on the edge line of the light emitting surface 1211 relative to the central optical axis W of the light emitting light source 110 is greater than or equal to 64°. In this solution, there is a large avoidance angle between the decorative member 220 and the light distribution member 120, thereby preventing the portion of the decorative member 220 protruding from the outer surface of the housing 210 from blocking the light emitted by the lighting assembly 100, thereby avoiding the influence of the decorative member 220 on the lighting range of the lighting assembly 100, thereby improving the lighting effect of the electronic device.

[0052] In the above scheme, the portion of the decorative member 220 protruding from the outer surface of the housing 210 mainly refers to the portion of the decorative member 220 that supports the lens. Specifically, the light-emitting surface 1211 may have a first edge line. The decorative member 220 may include a substrate 221 and at least one lens support portion 222, wherein the lens support portion 222 is used to support the lens, and the lens of the camera module in the electronic device is opposite to the lens. The first through hole 2201 may be provided on the substrate 221, and at least part of the lens support portion 222 may protrude from the outer surface of the housing 210. The lens support portion 222 is arranged side by side with the first through hole 2201. The outer peripheral surface of the lens support portion 222 has a second edge line on the side away from the substrate 221. Here, the side of the lens support portion 222 away from the substrate 221 can be understood as the side of the lens support portion 222 protruding from the outer surface of the housing 210, that is, the highest point of the decorative member 220.

[0053] In the same cross-section of the electronic device, the cross-section of the first edge line is the first intersection 1211c, and the cross-section of the second edge line of the lens support portion 222 adjacent to the lighting assembly 100 is the second intersection 2221. At this time, the angle between the line connecting the first intersection 1211c and the second intersection 2221 and the central optical axis W of the light emitting light source 110 can be greater than or equal to 64°.

[0054] The cross-section in the above embodiments can be a cross-sectional view or a longitudinal section. The cross-sectional view and the longitudinal section are two perpendicular sections. However, regardless of the direction of the section, it needs to pass through the first edge line and the second edge line. Therefore, according to the different placement positions of the electronic device, the section direction can be flexibly selected.

[0055] In another alternative solution, the lighting assembly 100 may further include a reflector 130. The reflector 130 is disposed on the side where the light incident surface 1221 is located. A reflecting surface may be provided on the side of the reflector 130 facing the light incident surface 1221. The reflector 130 may be provided with an avoidance hole 131, and the avoidance hole 131 may be disposed opposite to the light-emitting light source 110. In this solution, the reflector 130 can reflect some of the light reflected by the light incident surface 1221 back to the light incident surface 1221 again, thereby further improving the light utilization efficiency. In addition, the reflector 130 can also reflect external ambient light, which is beneficial to achieving a light-shielding effect and avoiding external light from entering the electronic device. In addition, the reflector 130 can also increase the brightness of the texture area 1222, which is beneficial to further improving the appearance effect of the electronic device.

[0056] Optionally, the reflecting surface of the reflector 130 can be a diffuse reflecting surface or a specular reflecting surface. In an alternative solution, the reflector 130 can be made of white PET (polyethylene terephthalate). Of course, the reflector 130 can also be made of other materials, which are not limited in this article.

[0057] In the above solution, the outer side wall of the light distribution member 120 can be attached to the inner wall of the first through hole 2201.

[0058] In another alternative embodiment, the light distribution member 120 may include a main body portion 1201 and a protruding portion 1202. The protruding portion 1202 is stacked with the main body portion 1201. The surface of the protruding portion 1202 facing away from the main body portion 1201 can be the first surface 121, and the surface of the main body portion 1201 facing away from the protruding portion 1202 can be the second surface 122. In the arrangement direction of the protruding portion 1202 and the main body portion 1201, the orthographic projection of the protruding portion 1202 can be located within the orthographic projection of the main body portion 1201, and the area of the orthographic projection of the protruding portion 1202 can be smaller than the area of the orthographic projection of the main body portion 1201. At this time, the light distribution member 120 is a frustum-shaped structure. The main body portion 1201 can be attached to the inner surface of the device main body 200, and at least a part of the protruding portion 1202 can be located within the first through hole 2201. Here, it means that the part of the main body portion 1201 protruding from the protruding portion 1202 is attached to the inner surface of the device main body 200.

[0059] In this solution, the part of the main body 1201 protruding from the protruding part 1202 is attached to the inner surface of the device main body 200. Therefore, the main body 1201 can form a limit with the inner surface of the device main body 200, thereby avoiding the risk of the light distribution member 120 falling out of the first through hole 2201, and further improving the assembly reliability and safety of the electronic device.

[0060] The electronic device disclosed in this application may further include a fill light, and the fill light can perform fill light for the shooting operation of the electronic device. In one solution, the device main body 200 may further be provided with a second through hole 2202. The fill light is installed in the second through hole 2202. Specifically, the fill light may include a fill light source and a fill light cover. The fill light source may be located in the accommodation cavity, and the fill light cover may be installed in the second through hole 2202. At this time, the light emitted by the fill light source passes through the fill light cover and then shoots out of the electronic device, thereby realizing the fill light operation.

[0061] In another alternative embodiment, the light-emitting light source 110 may have a first position and a second position. When the light-emitting light source 110 is in the first position, the light-emitting light source 110 may be disposed opposite to the light distribution member 120. When the light-emitting light source 110 is in the second position, the light-emitting light source 110 may be disposed opposite to the fill light cover. In this solution, the fill light and the lighting assembly 100 share a light source, so the structure of the electronic device is further simplified. At this time, the same light source can achieve different light spot effects.

[0062] Optionally, the electronic device may be provided with a lever or a knob, and the lever or the knob is connected to the light-emitting light source 110, so as to be able to drive the light-emitting light source 110 to switch between the first position and the second position. Alternatively, a drive motor may be provided in the electronic device, and the drive motor is connected to the light-emitting light source 110. At this time, the drive motor drives the light-emitting light source 110 to switch between the first position and the second position.

[0063] The electronic device disclosed in the embodiments of this 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, etc. The embodiments of this application do not limit the specific types of electronic devices.

[0064] The embodiments of the present application have been described above with reference to the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the spirit of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
