[0002] The present specification relates to the technical field of lighting devices, and in particular to an electronic device. Background Art

[0003] At present, many products are designed with light-emitting devices, which can serve as an indication and enhance the aesthetics. However, for many products with small spaces, it is difficult to design complex lighting. Moreover, the light source contains metal, which may interfere with the functions of other modules in the product (such as antennas). Therefore, the light source needs to be far enough away from other affected modules. This requires the volume of the light source to be as small and concentrated as possible, and the volume of the equipment should be reduced as much as possible without affecting other modules.

[0004] Therefore, it is necessary to provide an electronic device to achieve miniaturization and integration of light sources. Summary of the invention

[0005] This specification provides an electronic device that can reduce the volume of a light source and improve the concentration of the light source.

[0006] An embodiment of the present specification provides an electronic device, including a shell and a light-emitting component, wherein the light-emitting component is mounted on the shell and includes a light source and a light guide, wherein the light source is configured to emit light outward, and the light guide includes a light incident surface and a light emitting surface, wherein the light incident surface faces the center of the shell, the light source is opposite to the light incident surface, the light emitting surface is not parallel to the light incident surface, the light incident surface is located at an end of the light emitting surface close to the center of the shell, and the light emitting surface is exposed outside the shell.

[0007] In some embodiments, the light-emitting component further includes a reflector, which is disposed on one side of the light guide and blocks at least a portion of the surface of the light guide other than the light incident surface and the light emitting surface.

[0008] In some embodiments, the at least partial surface includes a surface of the light guide member opposite to the light emitting surface.

[0009] In some embodiments, the reflective element includes a top wall and a side wall, the top wall is arranged opposite to the surface of the light guide element opposite to the light emitting surface; the side wall is connected to the top wall and is located on a side of the top wall close to the light guide element and is distributed around the light guide element.

[0010] In some embodiments, a surface of the light guide member opposite to the light emitting surface is provided with a plurality of light emitting guiding points.

[0011] In some embodiments, one of the plurality of light exit light guiding points comprises a groove.

[0012] In some embodiments, the surface of the light guide opposite to the light emitting surface is inclined relative to the light emitting surface, and the distance between the end of the surface of the light guide opposite to the light emitting surface away from the light incident surface is closer to the light emitting surface than the distance between the end of the surface close to the light incident surface.

[0013] In some embodiments, a plurality of light incident guiding points are disposed on the light incident surface.

[0014] In some embodiments, one of the plurality of light entry light guide points comprises a protrusion.

[0015] In some embodiments, the protrusion comprises a plurality of intersecting surfaces.

[0016] In some embodiments, the housing includes a mounting hole, the light emitting surface is exposed outside the housing through the mounting hole, and a contour of the mounting hole matches a contour of the light emitting surface.

[0017] In some embodiments, when there are multiple light guides, the light guides whose distances are within a preset first threshold are connected by a connecting member, and the light transmittance of the connecting member is lower than a preset second threshold.

[0018] In some embodiments, the connecting member and the connected light guide member are integrally formed by double-shot injection molding.

[0019] In summary, in the electronic device provided in the embodiments of the present specification, the light incident surface and the light emitting surface of the light guide are arranged as non-parallel surfaces. The light incident surface is arranged at one end of the light emitting surface close to the center of the shell and faces the center of the shell. Therefore, the light incident surface is closer to the center of the shell relative to the light emitting surface. And the light source is opposite to the light incident surface. Therefore, the light source can be closer to the center of the shell. No matter where and in what direction the light emitting surface is located, the light source can be concentrated in the direction close to the center of the shell, so that the light source is located in the area of ​​the center of the shell, reducing the volume of the light source and improving the concentration of the light source. At the same time, since the light incident surfaces all face the center of the shell, under complex lighting designs, no matter where and in what direction the light emitting surface is located, the light source only needs to be opposite to the light incident surface, thereby making the arrangement of the light source simpler.

[0031] The following description provides specific application scenarios and requirements of this specification, with the purpose of enabling those skilled in the art to make and use the contents of this specification. Various local modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure is not limited to the embodiments shown, but to the widest scope consistent with the claims.

[0032] The terms used herein are only used for the purpose of describing specific example embodiments and are not restrictive. For example, unless the context clearly indicates otherwise, the singular forms "one", "an" and "the" used herein may also include plural forms. When used in this specification, the terms "include", "comprise" and / or "contain" mean the existence of the associated integers, steps, operations, elements and / or components, but do not exclude the existence of one or more other features, integers, steps, operations, elements, components and / or groups or other features, integers, steps, operations, elements, components and / or groups may be added to the system / method. When used in this specification, the term "A on B" can mean that A is directly adjacent to B (above or below), or it can mean that A is indirectly adjacent to B (i.e., there is some material between A and B); the term "A in B" can mean that A is all inside B, or it can mean that A is partially inside B.

[0033] In view of the following description, these and other features of the present disclosure, as well as the operation and function of the related elements of the structure, and the economy of the combination and manufacture of the parts can be significantly improved. Reference is made to the accompanying drawings, all of which form a part of the present disclosure. However, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present disclosure.

[0034] The following description may significantly improve these and other features of the present disclosure, as well as the operation and function of the relevant elements of the structure, and the economic efficiency of the combination and manufacture of the components. All of these refer to the accompanying drawings that form a part of the present disclosure. However, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present disclosure. It should also be understood that the drawings are not drawn to scale.

[0035] At present, many products are designed with light-emitting devices, which can play an indicating role on the one hand, and enhance the aesthetic effect on the other hand. However, for many products with small space, it is difficult to design complex lighting. Especially for communication devices, since the communication devices are equipped with antennas, in order to ensure the stability of the antenna, it is necessary to leave enough clearance area for the antenna. Parts containing metal cannot be set in the clearance area of ​​the antenna. And the light source contains metal. Therefore, the light source needs to be far enough away from the antenna module. This requires the volume of the light source to be as small and concentrated as possible, and the volume of the equipment should be reduced as much as possible without affecting other modules.

[0036] The electronic device provided in the embodiment of this specification utilizes a side-emitting light guiding solution to set the light source on the side of the light guide. The light incident surface of the light guide is not parallel to the light emitting surface, and the light incident surface is arranged at one end of the light emitting surface close to the center of the shell and faces the center of the shell, so that the light incident surface is closer to the center of the shell relative to the light emitting surface. Since the light source is opposite to the light incident surface, the light source emits light on the side of the light emitting surface of the light guide, and the light is absorbed into the light incident surface from the side of the light emitting surface. Under the side-emitting light guiding solution, the light source can be made closer to the center of the shell. Such a setting method makes it possible to concentrate the light source in the direction close to the center of the shell no matter where and in what direction the light emitting surface is located, so that the light source is located in the area of ​​the center of the shell, thereby reducing the volume of the light source and improving the concentration of the light source. At the same time, since the light incident surfaces all face the center of the shell, under complex lighting designs, no matter where and in what direction the light emitting surface is located, the light source only needs to be opposite to the light incident surface, thereby making the light source arrangement simpler.

[0037] The electronic device provided in this specification can be any form of electronic device and can be applied to any scenario. Electronic devices include but are not limited to payment devices, wearable devices, smart home appliances, and the like. A communication module can be installed in the electronic device. The communication module can be used to communicate with other electronic devices to exchange information. The communication module can transmit and / or receive radio frequency signals. A communication antenna is provided in the communication module, and radio frequency signals are transmitted and / or received through the communication antenna. The communication module can be a wireless communication module, such as any one or more of a WiFi module, a Bluetooth module, and an NFC (NearField Communication, referred to as NFC, near field communication) module. The communication module can be an active communication module operating in active mode, or a passive communication module operating in passive mode, or a combination of an active communication module and a passive communication module. The active mode can be that the active communication module actively transmits radio frequency signals to identify and read other passive communication devices operating in passive mode. The passive mode can be to receive or sense other active communication devices operating in active mode located in the sensing area (usually the antenna coverage area) to communicate with the active communication device. Among them, near field communication technology is widely used for its advantages of short communication distance, fast transmission rate and high security. In some embodiments, the communication module in the electronic device provided in this specification is a near field communication module. The electronic device provided in this specification can be applied to scenarios such as payment through the communication module, ordering through the communication module, information transmission through the communication module, and device connection through the communication module.

[0038] The electronic device is taken as a payment device as an example for explanation. Figure 1FIG. 1 is a schematic diagram of an application scenario of an electronic device 100 provided according to an embodiment of the present specification. The electronic device 100 can be used as a passive device working in a passive mode to interact with an active device 200 working in an active mode. Figure 1 As shown in (a) of FIG. 1 , when a user needs to pay, he or she can place his or her active device 200 (such as a mobile phone, watch, bracelet, etc.) with a communication module close to the electronic device 100 provided by the embodiment of this specification set by the merchant. Thus, the electronic device 100 can sense the user's active device 200 through the communication module and communicate with it to transmit payment information. Figure 1 As shown in (b) of FIG. 1 , the user's active device 200 can display the corresponding payment page according to the payment information. When the user performs a payment operation on the active device 200 according to the payment page (such as the user clicks the payment control "Confirm Payment" displayed on the payment page) and completes the payment, as shown in FIG. Figure 1 As shown in (c) in the figure, the user's active device 200 can display the payment completion interface, thereby completing the user's payment to the merchant.

[0039] As another example, the electronic device is taken as a food ordering device for explanation. Figure 2 FIG. 1 is a schematic diagram showing another application scenario of an electronic device 100 provided according to an embodiment of the present specification. The electronic device 100 can be used as a passive device operating in a passive mode to interact with an active device 200 operating in an active mode. For example, Figure 2 As shown in (a) of FIG. 1 , when a user needs to order food, he or she can place his or her active device 200 (such as a mobile phone, watch, bracelet, etc.) with a communication module function close to the electronic device 100 provided in the embodiment of this specification set on the dining table. Thus, the electronic device 100 can sense the user's active device 200 through the communication module and communicate with it to transmit the order information. Figure 2 As shown in (b) of FIG. 1 , the user's active device 200 can display the corresponding ordering page according to the ordering information. After the user completes the ordering operation according to the ordering page on the active device 200 (for example, the user selects "item 1" and "item 3" on the ordering page and clicks the control "confirm selection" for confirming the order), as shown in FIG. Figure 2 As shown in (c) in the figure, the user's active device 200 can display the order completion interface, thereby completing the user's convenient ordering operation.

[0040] Of course, electronic devices can also be used as active devices, which will not be described in detail in this specification. It should be noted that the above electronic devices are only exemplary. Those skilled in the art should understand that other forms of electronic devices that can emit light are also within the scope of protection of this specification.

[0041] Figure 3FIG. 1 shows a front view of an electronic device 100 provided according to an embodiment of this specification. Figure 3 As shown, the electronic device 100 includes a housing 120 and a light emitting assembly 140. The electronic device 100 also includes a communication module ( Figure 2 not shown).

[0042] The housing 120 is the mounting base of the electronic device 100. The light-emitting component 140 and other modules (such as a communication module) of the electronic device 100 can be mounted on the housing 120. Mounting on the housing 120 can be direct mounting or indirect mounting. Direct mounting can be directly connected to and mounted on the housing 120. Indirect mounting can be connected to and mounted on the housing 120 through other connection structures. Mounting on the housing 120 can be inside the housing 120 or outside the housing 120. Mounting inside the housing 120 can be that the portion mounted with the housing 120 is located inside the housing 120, and other portions can be located inside or outside the housing 120. Mounting outside the housing 120 can be that the portion mounted with the housing 120 is located outside the housing 120, and other portions can be located inside or outside the housing 120.

[0043] The housing 120 may be a thin-walled structure. The housing 120 may have a housing cavity for accommodating other modules. The housing cavity may be an open housing cavity. In some embodiments, the electronic device 100 may also include a cover. The cover may be connected to the housing 120 to close the housing cavity. In some embodiments, the electronic device 100 may not include a cover. In some embodiments, other parts may also serve as the cover. The housing 120 may include a bottom plate and a side plate. The side plate is disposed on one side of the bottom plate and is connected to the bottom plate. The bottom plate and the side plate together define the housing cavity. The outer contour of the housing 120 may be any shape, such as a square, a rectangle, a circle, an ellipse, a triangle, a polygon, or even an irregular shape, etc. The housing 120 may be symmetrical or asymmetrical. The outer contour of the housing 120 may be adaptively adjusted according to product design requirements. The inner wall of the housing 120 may be provided with a mounting structure for connecting to other modules according to installation requirements. The material of the housing 120 may be any material, such as a metal material, a plastic material, a polymer material, etc. This specification does not limit this. Figure 3 The outer contour of the housing 120 of the electronic device 100 shown in the figure is circular. Those skilled in the art should understand that the outer contour of the housing 120 is in other shapes and is also within the protection scope of this specification.

[0044] The light emitting component 140 is configured to emit light. In some embodiments, the electronic device 100 may include a group of light emitting components 140. In some embodiments, the electronic device 100 may include multiple groups of light emitting components 140. The light emitting portion (also called the light emitting portion) of the light emitting component 140 may be designed in different shapes and arranged in different positions according to product design, product function and aesthetic requirements, and this specification does not limit this. Figure 3 For example, the electronic device 100 includes 6 groups of light-emitting components, namely a first light-emitting component 140(a), a second light-emitting component 140(b), a third light-emitting component 140(c), a fourth light-emitting component 140(d), a fifth light-emitting component 140(e) and a sixth light-emitting component 140(f).

[0045] As mentioned above, the electronic device 100 may further include a communication module. The form of the communication module is as mentioned above and will not be repeated here. As mentioned above, the communication module includes an antenna assembly. In order to ensure the stability of the antenna assembly, an antenna clearance area 160 is provided in the housing 120. No metal may appear in the antenna clearance area 160. Therefore, the light source in the light-emitting assembly 140 may not appear in the antenna clearance area 160. Figure 1 The shaded area in the middle is the position of the exemplary antenna clearance area 160 in the front view. Those skilled in the art should understand that the antenna clearance area 160 can also be located at other positions, and the position of the antenna clearance area 160 is adapted to the product structure design.

[0046] In some embodiments, the electronic device 100 may further include other modules ( Figure 3 The electronic device 100 may include a key module, a control module, etc. This specification does not limit other modules of the electronic device 100.

[0047] Figure 4 An exploded view of an electronic device 100 provided according to an embodiment of this specification is shown. Figure 4 The explosion direction shown is the explosion direction of the central axis 121 of the shell 120. Figure 4 As shown, the light emitting assembly 140 may be mounted on the housing 120. The light emitting assembly 140 includes a light source 142 and a light guide 144. In some embodiments, the light emitting assembly 140 may further include a reflector 146.

[0048] The light source 142 can be installed on the housing 120. Specifically, the light source 142 can be installed in the housing 120, such as in a receiving cavity. The light source 142 can emit light outward, such as visible light. As mentioned above, the antenna in the communication module includes an antenna clearance area 160. The distance between the light source 142 and the antenna of the communication module is greater than a preset antenna distance threshold, so that the light source 142 is located outside the antenna clearance area 160. The distance between the light source 142 and the antenna of the communication module is adapted to the minimum distance between the light source 142 and the antenna. That is, the distance between the position closest to the antenna in the light source 142 and the antenna. The size of the antenna clearance area 160 of different antennas may be different.

[0049] like Figure 4 As shown, the first light source 142(a) may be the light source in the first light emitting assembly 140(a). The first light source 142(b) may be the light source of the second light emitting assembly 140(b), the third light emitting assembly 140(c), the fourth light emitting assembly 140(d), the fifth light emitting assembly 140(e), and the sixth light emitting assembly 140(f).

[0050] The light guide 144 can conduct the light emitted by the light source 142 so that the light is emitted from a specified plane. The light guide 144 is a transparent or translucent plastic material part. Light can be conducted inside the light guide 144 by reflection, refraction, etc., and the light can be conducted to a specific position or shape through the light guide 144. The light guide 144 has a high refractive index and low light absorption performance. The light conductivity of the light guide 144 is higher than a preset light conductivity threshold. The light conductivity threshold can be 90%-98%, or 80%-90%, or even higher or lower. The material of the light guide 144 can be a plastic material, such as PC (polycarbonate) material, PMMA (polymethyl methacrylate) material, etc.

[0051] The first light guide 144(a) may be a light guide in the first light emitting component 140(a). The second light guide 144(b) may be a light guide in the second light emitting component 140(b). The third light guide 144(c) may be a light guide in the third light emitting component 140(c). The fourth light guide 144(d) may be a light guide in the fourth light emitting component 140(d). The fifth light guide 144(e) may be a light guide in the fifth light emitting component 140(e). The sixth light guide 144(f) may be a light guide in the sixth light emitting component 140(f).

[0052] The light guide 144 can be installed on the housing 120. The light guide 144 can include a light incident surface 144-1 and a light emitting surface 144-2. The light guide 144 mentioned here can be any one or more of the first light guide 144(a), the second light guide 144(b), the third light guide 144(c), the fourth light guide 144(d), the fifth light guide 144(e) or the sixth light guide 144(f). The light incident surface 144-1 faces the center of the housing 120, the light source 142 is opposite to the light incident surface 144-1, the light emitting surface 144-2 is not parallel to the light incident surface 144-1, the light incident surface 144-1 is located at one end of the light emitting surface 144-2 close to the center of the housing 120, and the light emitting surface 144-2 faces the outer surface of the housing 120 and is exposed outside the housing 120.

[0053] Here, the center of the housing 120 may be a central axis 121 of the housing 120. The central axis 121 of the housing 120 is not coplanar with the outer surface of the housing 120. The outer surface of the housing 120 may be a plane or a curved surface. When the outer surface of the housing 120 is a plane, the central axis 121 of the housing 120 may be perpendicular to the outer surface of the housing 120. When the outer surface of the housing 120 is a curved surface, the central axis 121 of the housing 120 may pass through the center of curvature of the outer surface of the housing 120 and point to the radial direction of the outer surface of the housing 120.

[0054] The light incident surface 144-1 is a surface where light enters. The light source 142 is disposed opposite to the light incident surface 144-1, and the light emitted by the light source 142 enters the interior of the light guide 144 through the light incident surface 144-1. The distance between the light source 142 and the light incident surface 144-1 is within a preset range, so that as much light as possible from the light source 142 is incident on the light incident surface 144-1, thereby reducing light leakage.

[0055] The light emitting surface 144-2 is the surface from which the light is emitted. The light emitting surface 144-2 is exposed outside the housing 120, so that the light emitted from the light emitting surface 144-2 can be exposed to the outside of the housing 120 to achieve a lighting effect. The light emitting surface 144-2 can face the outer surface of the housing 120. The light emitting surface 144-2 and the light incident surface 144-1 are not parallel. The light incident surface 144-1 and the light emitting surface 144-2 face different directions respectively. In some embodiments, the light emitting surface 144-2 and the light incident surface 144-1 can be arranged vertically. In some embodiments, there can be a certain angle between the light emitting surface 144-2 and the light incident surface 144-1, such as an acute angle, a right angle or an obtuse angle. The light incident surface 144-1 is located on the side of the light emitting surface 144-2. In other words, the light of the light source 142 is absorbed from the side of the light emitting surface 144-2 into the light incident surface 144-1 and then emitted to the light emitting surface 144-2. In some embodiments, the light incident surface 144-1 is located at one end of the light emitting surface 144-2 close to the center of the shell 120. That is, relative to the light emitting surface 144-2, the position of the light incident surface 144-1 is closer to the center of the shell 120. Therefore, the light source 142 can be closer to the center of the shell 120. No matter where and in what direction the light emitting surface 144-2 is located, the light source 142 can be concentrated in the direction close to the center of the shell 120, so that the light source 142 is located in the area at the center of the shell 120, the volume of the light source 142 is reduced, and the concentration of the light source 142 is improved. At the same time, since the light incident surface 144-1 faces the center of the shell 120, under complex lighting design, no matter in what direction and at what position the light emitting surface 144-2 is located, the light source 142 only needs to be opposite to the light incident surface 144-1, so that the arrangement of the light source 142 is simpler. That is to say, in a complex lighting design, no matter in what direction and position the light emitting surface 144 - 2 is located, the light emitting direction of the light source 142 is in the same plane, or in a parallel plane, which will greatly reduce the difficulty of arranging the light source 142.

[0056] There are many ways to install the light guide 144 on the housing 120. In some embodiments, the light guide 144 can be installed outside the housing 120 and expose the light emitting surface 144-2 to the outside of the housing 120, such as the first light guide 144 (a). In some embodiments, a mounting hole 123 may be provided on the housing 120. The light guide 144 can be installed inside the housing 120, such as inside a receiving cavity. In this case, the light emitting surface 144-2 can pass through the mounting hole 123 and be exposed to the outside of the housing 120. For example, the second light guide 144 (b), the third light guide 144 (c), the fourth light guide 144 (d), the fifth light guide 144 (e) or the sixth light guide 144 (f). In this case, the contour of the mounting hole 123 matches the contour of the light emitting surface 144-2.

[0057] When the light guide 144 is mounted on the housing 120, a portion of the surface on the housing 120 is opposite to a portion of the side surface of the light guide 144. The side surface of the light guide 144 may be a surface connected to the light exiting surface 144-2 or the light entering surface 144-1. The surface on the housing 120 opposite to the side surface of the light guide 144 may shield the side surface of the light guide 144, thereby reflecting the light emitted from the side surface of the light guide 144 and reducing light leakage.

[0058] In some embodiments, when there are multiple light guides 144, the light guides 144 whose distance among the multiple light guides 144 is within a preset first threshold are connected by a connector 144-5. It should be noted that the transmittance of the connector 144-5 is lower than the preset second threshold. The material of the connector 144-5 is different from that of the light guide 144. The connector 144-5 can reflect the light from the light guide 144 that is directed toward the connector 144-5. In other words, when the distance between the multiple light guides 144 is close, the multiple light guides 144 can be connected by the connector 144-5, thereby improving the integration of the light guides 144 and reducing the difficulty of installing the light guides 144. At the same time, the light isolation between different light guides 144 can be improved to avoid light crosstalk.

[0059] The connection method between the connecting member 144 - 5 and the connected light guide member 144 may include various methods, such as bonding, hot melting, etc.

[0060] In some embodiments, the connector 144-5 is integrally formed with the connected light guide 144. In some embodiments, the connector 144-5 is integrally formed with the connected light guide 144 by double-shot injection molding. Double-shot injection molding refers to a molding process in which two different materials are injected into the same mold, thereby realizing a molded part formed of two materials. Some of the two materials are of different colors, and some are of different hardness and softness, thereby improving the aesthetics and assembly performance of the product.

[0061] As mentioned above, in some embodiments, the light emitting assembly 140 further includes a reflector 146. The reflector 146 can be mounted on the housing 120. The reflector 146 is disposed on one side of the light guide 144 and blocks at least part of the surface outside the light incident surface 144-1 and the light emitting surface 144-2 of the light guide 144. The reflector 146 can be disposed on the side of the light guide 144 away from the light emitting surface 144-2. The reflector 146 is used to reflect the light emitted from the light guide 144 so that the reflected light enters the light guide 144 again. The reflector 146 has a low light transmittance. When the light is emitted from the light guide 144 and directed toward the reflector 146, the light is reflected by the reflector 146 and enters the light guide 144 again, thereby reducing the leakage of light. It should be noted that in some embodiments, according to the position and size of the reflector 146, multiple light emitting assemblies 140 can share one reflector 146. for example, Figure 4 In the electronic device shown, the first reflector 146(a) may be a reflector in the first light-emitting component 140(a). The second reflector 146(b) may be a reflector in the second light-emitting component 140(b), the third light-emitting component 140(c), the fourth light-emitting component 140(d), and the fifth light-emitting component 140(e). The third reflector 146(c) may be a reflector in the sixth light-emitting component 140(f).

[0062] In some embodiments, at least part of the surface blocked by the reflector 146 includes the surface of the light guide 144 opposite to the light emitting surface 144-2. The reflector 146 here can be any one or more of the first reflector 146(a), the second reflector 146(b) or the third reflector 146(c). As mentioned above, the light emitting surface 144-2 faces the outside of the housing 120. Therefore, the surface of the light guide 144 opposite to the light emitting surface 144-2 faces the inside of the housing 120. The reflector 146 is arranged on the side of the light guide 144 away from the light emitting surface 144-2, and can reflect the light emitted from the surface opposite to the light emitting surface 144-2.

[0063] In some embodiments, the reflector 146 includes a top wall 146-1 and a side wall 146-2. The top wall 146-1 is disposed opposite to the surface of the light guide 144 opposite to the light emitting surface 144-2. The side wall 146-2 is connected to the top wall 146-1, is located on a side of the top wall 146-1 close to the light guide 144, and is distributed around the light guide 144. At this time, the top wall 146-1 can reflect light emitted from the surface opposite to the light emitting surface 144-2. The side wall 146-2 can reflect light emitted from part of the side surface of the light guide 144. The device composed of the reflector 146 and the housing 120 can reflect light emitted from other surfaces of the light guide 144 except the light incident surface 144-1 and the light emitting surface 144-2, thereby preventing light from being emitted from other surfaces except the light emitting surface 144-2 and preventing light leakage.

[0064] The light source 142 may include a light emitting element and a circuit board. The light emitting element may be a light emitting lamp bead, such as an LED lamp bead. The light emitting element is configured to emit light outward, such as visible light. The light emitting element may be mounted on a circuit board and electrically connected to the circuit board. The circuit board may provide electrical energy for the light emitting element.

Figure 5 The light source shown may be a first light source 142(a). The first light source 142(a) may include a plurality of first light-emitting elements 142-1(a) and a first circuit board 142-2(a). The plurality of first light-emitting elements 142-1(a) are mounted on the first circuit board 142-2(a) and are electrically connected to the first circuit board 142-2(a). The first circuit board 142-2(a) provides electrical energy to the plurality of first light-emitting elements 142-1(a). The first light-emitting element 142-1(a) may be a light-emitting lamp bead, such as an LED lamp bead. The first light-emitting element 142-1(a) may be a light source of a single color or a light source of different colors. The plurality of first light-emitting elements 142-1(a) are distributed around the central axis 121 of the housing 120. The light emission direction of each first light-emitting element 142-1(a) is a radial direction. The direction indicated by the arrow in the figure is the light emission direction of some of the first light-emitting elements 142-1(a). Figure 5 The arrangement, size, and position of the first light emitting element 142-1(a) in the first light source 142(a) are shown for exemplary purposes only. A person skilled in the art should understand that the arrangement and size of the first light emitting element 142-1(a) can be designed and adjusted according to the lighting effect, and this specification does not limit this.

[0066] Figure 6 A schematic structural diagram of another light source 142 provided according to an embodiment of the present specification is shown. Figure 6 The light source shown may be a second light source 142(b). The second light source 142(b) may include a second light emitting element 142-1(b), a third light emitting element 142-1(c), a fourth light emitting element 142-1(d), a fifth light emitting element 142-1(e), a sixth light emitting element 142-1(f), and a second circuit board 142-2(b). The second light emitting element 142-1(b), the third light emitting element 142-1(c), the fourth light emitting element 142-1(d), the fifth light emitting element 142-1(e), the sixth light emitting element 142-1(f), and the second circuit board 142-2(b) are mounted on the second circuit board 142-2(b) and are electrically connected to the second circuit board 142-2(b). The second circuit board 142-2(b) provides electrical energy to the second light-emitting element 142-1(b), the third light-emitting element 142-1(c), the fourth light-emitting element 142-1(d), the fifth light-emitting element 142-1(e), and the sixth light-emitting element 142-1(f). The second light-emitting element 142-1(b), the third light-emitting element 142-1(c), the fourth light-emitting element 142-1(d), the fifth light-emitting element 142-1(e), and the sixth light-emitting element 142-1(f)(a) may be light-emitting lamp beads, such as LED lamp beads. The direction indicated by the arrow in the figure is the light emission direction of the second light-emitting element 142-1(b), the third light-emitting element 142-1(c), the fourth light-emitting element 142-1(d), the fifth light-emitting element 142-1(e), and the sixth light-emitting element 142-1(f). Figure 6 The arrangement, size, and position of the second light emitting element 142-1(b), the third light emitting element 142-1(c), the fourth light emitting element 142-1(d), the fifth light emitting element 142-1(e), and the sixth light emitting element 142-1(f) in the second light source 142(b) are shown for exemplary purposes only. Those skilled in the art should understand that the arrangement and size of the second light emitting element 142-1(b), the third light emitting element 142-1(c), the fourth light emitting element 142-1(d), the fifth light emitting element 142-1(e), and the sixth light emitting element 142-1(f) can be designed and adjusted according to the lighting effect, and this specification does not limit this.

[0067] As mentioned above, the light incident surface 144-1 is located at the end of the light emitting surface 144-2 close to the center of the housing 120, so that the light source 142 can be moved closer to the center of the housing 120, thereby reducing the volume of the light source 142 and improving the integration of the light source 142. Therefore, when the light source 142 is close to the center of the housing 120 and the distance is close enough, different light sources 142 can share the same circuit board, such as Figure 6As shown, this will further improve the integration level of the light source 142, reduce the volume of the light source 142, and reduce the cost and difficulty of processing and installation. At the same time, since the light incident surface 144-1 faces the center of the shell 120, different light-emitting elements can be arranged in any direction and position facing the center of the shell 120, further increasing the flexibility of the arrangement of the light-emitting elements. Such an arrangement makes it possible for the directions of the light incident surfaces 144-1 of different light guides 144 to be different even if the directions of the light-emitting surfaces 144-2 are the same, thereby further improving the concentration of the light source 142 and reducing the volume of the light source 142.

[0068] Fig. 7A A first side view of a light guide 144 provided according to an embodiment of the present specification is shown; Figure 7B A second side view of a light guide 144 provided according to an embodiment of the present specification is shown. Figure 7B It can be from Fig. 7A A view from above.

[0069] Fig. 7A and Figure 7B The light guide 144 shown may be the sixth light guide 144 ( f ). Fig. 7A and Figure 7B As shown, the light guide 144 includes a light incident surface 144-1 and a light emitting surface 144-2. The light incident surface 144-1 is disposed on one side of the light emitting surface 144-2.

[0070] A plurality of light-emitting guiding points 144-31 are provided on the surface 144-3 of the light guide 144 opposite to the light-emitting surface 144-2. The light-emitting guiding points 144-31 can destroy the incident angle of the light, so that the light is diffused to different angles, so that the concentrated light becomes more uniform, thereby improving the uniformity of the light and the light transmission efficiency. One of the plurality of light-emitting guiding points 144-31 can be a protrusion or a groove. When the light-emitting guiding point 144-21 is a groove, the groove can be a curved groove or a groove formed by the intersection of multiple inclined surfaces. The plurality of light-emitting guiding points 144-31 can be a plurality of tiny structures distributed on the surface 144-3 opposite to the light-emitting surface 144-2. The size of the light-emitting guiding point 144-31 can reach the millimeter, micrometer or even nanometer level. The multiple light-emitting light-guiding points 144-31 may be evenly or unevenly distributed on the surface 144-3 opposite to the light-emitting surface 144-2. The structures and sizes of the multiple light-emitting light-guiding points 144-31 may be consistent or inconsistent. This specification does not limit this. The multiple light-emitting light-guiding points 144-31 may be formed by laser engraving, by printing, or by injection molding of the light guide 144.

[0071] The surface 144-3 of the light guide 144 that is opposite to the light emitting surface 144-2 is inclined relative to the light emitting surface 144-2. The end of the surface 144-3 of the light guide 144 that is opposite to the light emitting surface 144-2 that is far away from the light incident surface 144-1 is closer to the light emitting surface 144-2 than the end that is close to the light incident surface 144-1 is to the light emitting surface 144-2. In other words, among the surface 144-3 of the light guide 144 that is opposite to the light emitting surface 144-2, the farther the end is from the light incident surface 144-1, the closer the distance is to the light emitting surface 144-2. This arrangement allows light to be evenly emitted toward the light emitting surface 144-2, rather than being concentrated at the end of the light emitting surface 144-2 that is far away from the light incident surface 144-1. This makes the light emitted from the light emitting surface 144-2 more uniform, effectively ensuring the equivalent uniformity and consistency of the light emitting surface 144-2.

[0072] The surface of the light incident surface 144-1 is provided with a plurality of light incident guiding points 144-13. The light incident guiding points 144-13 can destroy the incident angle of the light, so that the light is diffused to different angles, and the concentrated light becomes more uniform, thereby improving the uniformity of the light and the light transmission efficiency. The plurality of light incident guiding points 144-13 can be distributed along the width direction of the light incident surface 144-1, so that the light can be uniformly incident into the light incident surface 144-1 along the width direction of the light incident surface 144-1. The width direction of the light incident surface 144-1 can be perpendicular to the direction of incidence of the light. One of the plurality of light incident guiding points 144-13 can be a protrusion or a groove. When the light incident guiding point 144-13 is a protrusion, the protrusion can be an arc-shaped protrusion or a protrusion including a plurality of intersecting surfaces (such as a tooth shape, a cone shape, or a column shape). The multiple light incident light guiding points 144-13 can be multiple tiny structures distributed on the light incident surface 144-1. The size of the light incident light guiding points 144-13 can reach the millimeter, micrometer or even nanometer level. The multiple light incident light guiding points 144-13 can be evenly or unevenly distributed on the light incident surface 144-1. The structures and sizes of the multiple light incident light guiding points 144-13 can be consistent or inconsistent. This specification does not limit this. The multiple light incident light guiding points 144-13 can be formed by laser engraving, can be formed by printing, and can also be formed when the light guide 144 is injection molded.

[0073] Figure 8 Shows Figure 3 Section view AA. Figure 8 An installation diagram of the light guide 144, the housing 120, and the light source 142 is shown. Fig. 9 Shows Figure 8 A partial enlarged view of part I in the middle. Fig. 9As shown, the first light guide 144(a) is installed on the periphery of the housing 120. The light incident surface 144-1 of the first light guide 144(a) is located at one end of the light emitting surface 144-2 close to the center of the housing 120. The light incident surface 144-1 is opposite to the first light emitting element 142-1(a). The first light reflector 146(a) and the housing 120 together block the surfaces other than the light incident surface 144-1 and the light emitting surface 144-2, thereby reflecting the light emitted from the light guide 144 from other surfaces and causing it to be emitted back to the light emitting surface 144-2 again, thereby ensuring that the light can be emitted from the light emitting surface 144-2 and avoiding light leakage.

[0074] Fig.10 Shows Figure 8 A partial enlarged view of the middle J part. Fig.10 As shown, the sixth light guide 144 (f) is installed inside the shell 120. The light emitting surface 144-2 of the sixth light guide 144 (f) is exposed to the outside of the shell 120 through the mounting hole 123 of the shell 120. The light incident surface 144-1 of the sixth light guide 144 (f) is located at one end of the light emitting surface 144-2 close to the center of the shell 120. The light incident surface 144-1 is opposite to the sixth light-emitting element 142-1 (f). The third reflector 146 (c) and the shell 120 jointly block the surfaces other than the light incident surface 144-1 and the light emitting surface 144-2, thereby reflecting the light emitted from the light guide 144 from other surfaces and causing it to be emitted back to the light emitting surface 144-2 again, thereby ensuring that the light can be emitted from the light emitting surface 144-2 and avoiding light leakage.

[0075] In summary, in the electronic device 100 provided in the embodiment of the present specification, the light incident surface 144-1 and the light emitting surface 144-2 of the light guide 144 are set as non-parallel surfaces. The light incident surface 144-1 is set at one end of the light emitting surface 144-2 close to the center of the shell 120 and faces the center of the shell 120. Therefore, the light incident surface 144-1 is closer to the center of the shell 120 relative to the light emitting surface 144-2. The light source 142 is opposite to the light incident surface 144-1. Therefore, the light source 142 can be closer to the center of the shell 120. Regardless of the position and direction of the light emitting surface 144-2, the light source 142 can be concentrated in the direction close to the center of the shell 120, so that the light source 142 is located in the area of ​​the center of the shell 120, reducing the volume of the light source 142 and improving the concentration of the light source 142. At the same time, since the light incident surface 144-1 faces the center of the shell 120, under complex lighting design, no matter what direction and position the light emitting surface 144-2 is located, the light source 142 only needs to be opposite to the light incident surface 144-1, thereby making the arrangement of the light source 142 simpler.
