Description

[0001] This application is a divisional application of the patent application filed on July 24, 2024, with application number 202411000500.5 and invention title "An Electronic Device". Technical Field

[0002] This specification relates to the field of lighting device technology, and more particularly to an electronic device. Background Technology

[0003] Many products now incorporate lighting devices, serving both as indicators and enhancing aesthetics. However, designing complex lighting for products with limited space presents significant challenges. Furthermore, the presence of metal in the light source can potentially interfere with other modules within the product (such as antennas). Therefore, the light source needs to be kept sufficiently far away from affected modules. This necessitates minimizing and centralizing the light source, reducing the overall device size without impacting other modules.

[0004] Therefore, there is a need to provide an electronic device to achieve miniaturization and integration of the light source. Summary of the Invention

[0005] This specification provides an electronic device that can reduce the size of the light source and increase the concentration of the light source.

[0006] This specification provides an electronic device including a housing and a light-emitting component. The light-emitting component is mounted on the housing and includes a light source and a light guide. The light source is configured to emit light outward. The light guide includes an incident light surface and an exit light surface. The incident light surface faces the center of the housing. The light source is opposite to the incident light surface. The exit light surface is not parallel to the incident light surface. The incident light surface is located at the end of the exit light surface near the center of the housing, and the exit light surface is exposed outside the housing.

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

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

[0009] In some embodiments, the reflector includes a top wall and a side wall, the top wall being disposed opposite to the surface of the light guide that is opposite to the light-emitting surface; the side wall being connected to the top wall and located on the side of the top wall close to the light guide, and distributed around the light guide.

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

[0011] In some embodiments, one of the plurality of light-emitting light-guiding points includes 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 end of the light guide opposite to the light emitting surface that is farther from the light emitting surface is closer to the light emitting surface than the end that is closer to the light emitting surface.

[0013] In some embodiments, the light-incident surface is provided with a plurality of light-incident guide points.

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

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

[0016] In some embodiments, the housing includes a mounting hole through which the light-emitting surface is exposed outside the housing, the profile of the mounting hole matching the profile of the light-emitting surface.

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

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

[0019] In summary, in the electronic device provided in the embodiments of this specification, the light-incident surface and the light-exit surface of the light guide are set as non-parallel surfaces. The light-incident surface is located at the end of the light-exit surface near the center of the housing and faces the center of the housing. Therefore, the light-incident surface is closer to the center of the housing than the light-exit surface. The light source is opposite to the light-incident surface. Therefore, the light source can be closer to the center of the housing. Regardless of the position and direction of the light-exit surface, the light source can be concentrated towards the center of the housing, thereby placing the light source in the central area of ​​the housing, reducing the size of the light source, and increasing the concentration of the light source. At the same time, since the light-incident surface always faces the center of the housing, in complex lighting designs, regardless of the direction and position of the light-exit surface, the light source only needs to be opposite to the light-incident surface, thus simplifying the arrangement of the light source.

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

[0032] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not restrictive. For example, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. When used in this specification, the terms “comprising,” “including,” and / or “containing” mean the presence of the associated integers, steps, operations, elements, and / or components, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups, or the possibility of adding other features, integers, steps, operations, elements, components, and / or groups 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 that A and B are indirectly adjacent (i.e., there is some substance between A and B); the term “A within B” can mean that A is entirely inside B or that A is partially inside B.

[0033] In view of the following description, these and other features of this disclosure, as well as the operation and function of the related elements of the structure, and the economy of assembly and manufacture of the components, can be significantly improved. All of these form part of this disclosure with reference to the accompanying drawings. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this disclosure.

[0034] The following description can significantly improve these and other features of this disclosure, as well as the operation and function of related components of the structure, and the economic efficiency of the assembly and manufacture of the components. All of these are incorporated herein by reference to the accompanying drawings. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this disclosure. It should also be understood that the drawings are not drawn to scale.

[0035] Many products now incorporate lighting elements, serving both as indicators and enhancing aesthetics. However, designing complex lighting systems is challenging for products with limited space. This is especially true for communication devices, which contain antennas. To ensure antenna stability, sufficient clearance must be provided, and no metal components can be placed within this clearance. Since light sources contain metal, they must be kept a sufficient distance from the antenna module. This necessitates minimizing and centralizing the light source, reducing the overall device size without interfering with other modules.

[0036] The electronic device provided in the embodiments of this specification utilizes a side-emitting light guide scheme, placing the light source on the side of the light guide component. The light-incident surface and light-exit surface of the light guide component are not parallel, and the light-incident surface is located at the end of the light-exit surface near the center of the housing and faces the center of the housing, making the light-incident surface closer to the center of the housing than the light-exit surface. Since the light source is opposite to the light-incident surface, the light source emits light from the side of the light-exit surface of the light guide component, and the light is received from the side of the light-exit surface onto the light-incident surface. With this side-emitting light guide scheme, the light source can be closer to the center of the housing. This arrangement allows the light source to be concentrated towards the center of the housing regardless of the position and direction of the light-exit surface, thus placing the light source in the central area of ​​the housing, reducing the size of the light source, and increasing the concentration of the light source. Simultaneously, since the light-incident surfaces all face the center of the housing, in complex lighting designs, regardless of the direction and position of the light-exit surface, the light source only needs to be opposite to the light-incident surface, thus simplifying the light source arrangement.

[0037] The electronic device described in this manual 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, etc. A communication module may 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. The communication module is equipped with a communication antenna, through which radio frequency signals are transmitted and / or received. The communication module can be a wireless communication module, such as any one or more of WiFi, Bluetooth, and NFC (Near Field Communication) modules. The communication module can be an active communication module operating in active mode, a passive communication module operating in passive mode, or a combination of active and passive communication modules. In active mode, the active communication module can actively transmit radio frequency signals to identify and read other passive communication devices operating in passive mode. In passive mode, it can receive or sense other active communication devices operating in active mode located within the sensing area (usually the antenna coverage area) to communicate with those active communication devices. Near Field Communication (NFC) technology is widely used due to its advantages of short communication distance, high 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 used in scenarios such as making payments through the communication module, ordering food through the communication module, transmitting information through the communication module, and connecting devices through the communication module.

[0038] Let's take electronic devices as an example for explanation. Figure 1This diagram illustrates an application scenario of an electronic device 100 provided according to an embodiment of this specification. The electronic device 100 can interact with an active device 200 operating in active mode, functioning as a passive device operating in passive mode. Figure 1 As shown in (a), when a user needs to make a payment, they can bring their active device 200 (such as a mobile phone, watch, or bracelet) with a communication module close to the electronic device 100 provided in this embodiment of the specification, which is set up by the merchant. Thus, the electronic device 100 can sense the user's active device 200 through its communication module and communicate with it to transmit payment information. Then, as... Figure 1 As shown in (b), the user's active device 200 can then display the corresponding payment page based on the payment information. After the user completes the payment by performing a payment operation on the active device 200 according to this payment page (e.g., clicking the "Confirm Payment" control displayed on the payment page), as shown... Figure 1 As shown in (c), the user's active device 200 can then display the payment completion interface, thereby completing the user's payment to the merchant.

[0039] For example, let's take electronic devices as a way of ordering food. Figure 2 This diagram illustrates an application scenario of another electronic device 100 provided according to an embodiment of this specification. The electronic device 100 can interact with the active device 200 operating in active mode, acting as a passive device operating in passive mode. For example, as... Figure 2 As shown in (a), when a user needs to order food, they can bring their active device 200 with a communication module (such as a mobile phone, watch, or bracelet) close to the electronic device 100 provided in this embodiment of the specification, which is placed on the dining table. Thus, the electronic device 100 can sense the user's active device 200 through its communication module and communicate with it to transmit order information. Then, as... Figure 2 As shown in (b), the user's active device 200 can display the corresponding ordering page based on the ordering information. After the user completes the ordering operation on the active device 200 based on the ordering page (e.g., the user selects "Item 1" and "Item 3" on the ordering page and clicks the "Confirm Selection" control to confirm the order), as shown in (b), the user's active device 200 can display the corresponding ordering page. Figure 2 As shown in (c), the user's active device 200 can display the order completion interface, thereby enabling the user to conveniently place an order.

[0040] Of course, electronic devices can also be used as active devices, which will not be elaborated upon here. It should be noted that the above-described electronic devices are merely illustrative examples. Those skilled in the art should understand that other forms of light-emitting electronic devices are also within the scope of this specification.

[0041] Figure 3A front view of an electronic device 100 provided according to an embodiment of this specification is shown. Figure 3 As shown, the electronic device 100 includes a housing 120 and a light-emitting component 140. The electronic device 100 also includes a communication module (…). Figure 2 (Not shown in the image).

[0042] The housing 120 is the mounting base for the electronic device 100. The light-emitting component 140 and other modules (such as communication modules) of the electronic device 100 can be mounted on the housing 120. Mounting on the housing 120 can be direct or indirect. Direct mounting means directly connecting and installing to the housing 120. Indirect mounting means connecting and installing to the housing 120 through other connection structures. Mounting on the housing 120 can be inside or outside the housing 120. When mounted inside the housing 120, the mounting portion can be located inside the housing 120, while other portions can be located inside or outside the housing 120. When mounted outside the housing 120, the mounting portion can be located outside the housing 120, while 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 receiving cavity for accommodating other modules. The receiving cavity may be an open cavity. In some embodiments, the electronic device 100 may also include a cover plate. The cover plate may be connected to the housing 120 to close the receiving cavity. In some embodiments, the electronic device 100 may not include a cover plate. In some embodiments, other parts may also serve as the cover plate. The housing 120 may include a base plate and side plates. The side plates are disposed on one side of the base plate and connected to the base plate. The base plate and side plates together define the receiving cavity. The outer contour of the housing 120 may be of any shape, such as a square, rectangle, circle, ellipse, triangle, polygon, or even an irregular shape, etc. The housing 120 may be symmetrical or asymmetrical. The outer contour shape of the housing 120 may be adaptively adjusted according to product design needs. The inner wall of the housing 120 may be provided with mounting structures for connecting with other modules, according to installation requirements. The material of the housing 120 may be of any material, such as metal, plastic, polymer, etc. This specification does not limit this. Figure 3 The outer contour of the housing 120 of the electronic device 100 shown is circular. Those skilled in the art should understand that other shapes of the outer contour of the housing 120 are also within the scope of protection 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 part) of the light-emitting component 140 can be designed into different shapes and placed in different positions according to product design, product function, and aesthetic requirements; this specification does not limit this. Figure 3 For example, the electronic device 100 includes 6 light-emitting components, namely the first light-emitting component 140(a), the second light-emitting component 140(b), the third light-emitting component 140(c), the fourth light-emitting component 140(d), the fifth light-emitting component 140(e), and the sixth light-emitting component 140(f).

[0045] As previously described, the electronic device 100 may also include a communication module. The form of the communication module is as described above and will not be repeated here. As previously described, the communication module includes an antenna assembly. To ensure the stability of the antenna assembly's operation, an antenna clearance area 160 is provided within the housing 120. No metal may be present within the antenna clearance area 160. Therefore, the light source in the light-emitting component 140 may not be present within the antenna clearance area 160. Figure 1 The shaded area shows the exemplary location of the antenna clearance area 160 in the front view. Those skilled in the art will understand that the antenna clearance area 160 can also be located in other locations, and its location is adapted to the product structural design.

[0046] In some embodiments, the electronic device 100 may further include other modules ( Figure 3 (Not shown in the diagram), such as button modules, control modules, etc. This manual 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 direction of explosion along the central axis 121 of the casing 120. For example... Figure 4 As shown, the light-emitting component 140 can be mounted on the housing 120. The light-emitting component 140 includes a light source 142 and a light guide 144. In some embodiments, the light-emitting component 140 may also include a reflector 146.

[0048] The light source 142 can be mounted on the housing 120. Specifically, the light source 142 can be mounted inside the housing 120, such as within a cavity. The light source 142 can emit light outwards, such as visible light. As mentioned earlier, 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, such 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 the minimum distance between the light source 142 and the antenna. That is, the distance between the closest point of the light source 142 to the antenna and the antenna. The size of the antenna clearance area 160 can be different for different antennas.

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

[0050] The light guide 144 can conduct light emitted from the light source 142, allowing the light to exit from a designated plane. The light guide 144 is a transparent or translucent plastic component. Light can be conducted within the light guide 144 through reflection, refraction, etc., directing the light to a specific position or shape. The light guide 144 has a high refractive index and low light absorption. The light guide efficiency of the light guide 144 is higher than a preset light guide efficiency threshold. This threshold can be 90%-98%, 80%-90%, or even higher or lower. The light guide 144 can be made of plastic, such as PC (polycarbonate), PMMA (polymethyl methacrylate), etc.

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

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

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

[0054] The light-incident surface 144-1 is the surface through which light enters. The light source 142 is positioned opposite to the light-incident surface 144-1, and the light emitted by the light source 142 enters 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 from the light source 142 as possible is directed towards the light-incident surface 144-1, reducing light leakage.

[0055] The light-emitting surface 144-2 is the surface from which light is emitted. The light-emitting surface 144-2 is exposed outside the housing 120, allowing the light emitted from the light-emitting surface 144-2 to be exposed to the outside of the housing 120, achieving a lighting effect. The light-emitting surface 144-2 may 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. In some embodiments, the light-emitting surface 144-2 and the light-incident surface 144-1 may be arranged perpendicularly. In some embodiments, the light-emitting surface 144-2 and the light-incident surface 144-1 may form a certain angle, such as an acute angle, a right angle, or an obtuse angle. The light-incident surface 144-1 is located to the side of the light-emitting surface 144-2. That is, the light from the light source 142 enters the light-incident surface 144-1 from the side of the light-emitting surface 144-2 and then shines onto the light-emitting surface 144-2. In some embodiments, the light-incident surface 144-1 is located at the end of the light-emitting surface 144-2 near the center of the housing 120. That is, the light-incident surface 144-1 is closer to the center of the housing 120 than the light-emitting surface 144-2. Therefore, the light source 142 can be closer to the center of the housing 120. Regardless of the position and orientation of the light-emitting surface 144-2, the light source 142 can be concentrated towards the center of the housing 120, thus placing the light source 142 in the central region of the housing 120, reducing the volume of the light source 142, and increasing the concentration of the light source 142. Simultaneously, since the light-incident surface 144-1 always faces the center of the housing 120, in complex lighting designs, regardless of the orientation and position of the light-emitting surface 144-2, the light source 142 only needs to be opposite the light-incident surface 144-1, thus simplifying the arrangement of the light source 142. In other words, under complex lighting design, regardless of the direction and position of the light-emitting surface 144-2, the light emission direction of the light source 142 is always in the same plane or in a parallel plane, which will greatly reduce the difficulty of arranging the light source 142.

[0056] There are several ways in which the light guide 144 can be mounted on the housing 120. In some embodiments, the light guide 144 can be mounted outside the housing 120, exposing the light-emitting surface 144-2 outside the housing 120, such as the first light guide 144(a). In some embodiments, the housing 120 may be provided with a mounting hole 123. The light guide 144 can be mounted 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 outside the housing 120. For example, a second light guide 144(b), a third light guide 144(c), a fourth light guide 144(d), a fifth light guide 144(e), or a 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 of the housing 120 faces a portion of the side surface of the light guide 144. The side surface of the light guide 144 can be the surface connected to the light-emitting surface 144-2 or the light-incident surface 144-1. The surface of the housing 120 facing the side surface of the light guide 144 can block 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 that are within a preset first threshold distance are connected by connectors 144-5. It should be noted that the light transmittance of connectors 144-5 is lower than a preset second threshold. Connectors 144-5 are made of a different material than the light guides 144. Connectors 144-5 can reflect light rays from the light guides 144 that are directed towards them. That is, when multiple light guides 144 are close together, they can be connected by connectors 144-5, thereby improving the integration of the light guides 144, reducing the installation difficulty, and simultaneously improving the light isolation between different light guides 144, preventing light crosstalk.

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

[0060] In some embodiments, the connector 144-5 and the connected light guide 144 are integrally formed. In some embodiments, the connector 144-5 and the connected light guide 144 are integrally formed by two-shot injection molding. Two-shot injection molding refers to the molding process of injecting two different materials into the same mold, thereby achieving a part formed by two materials. Sometimes the two materials are different colors, and sometimes they are of different hardness, thereby improving the product's aesthetics and assembly performance.

[0061] As previously described, in some embodiments, the light-emitting component 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 a portion 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 opposite to the light-emitting surface 144-2. The reflector 146 is used to reflect light emitted from the light guide 144, so that the reflected light re-enters the light guide 144. The reflector 146 has low light transmittance. When light is emitted from the light guide 144 and strikes the reflector 146, the light is reflected by the reflector 146 and re-enters the light guide 144, thereby reducing light leakage. It should be noted that in some embodiments, depending on the position and size of the reflector 146, multiple light-emitting components 140 can share a single reflector 146. for example, Figure 4 In the illustrated electronic device, 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 a portion of the surface obscured by the reflector 146 includes the surface of the light guide 144 opposite to the light-emitting surface 144-2. The reflector 146 can be any one or more of a first reflector 146(a), a second reflector 146(b), or a third reflector 146(c). As previously described, the light-emitting surface 144-2 faces the exterior of the housing 120. Therefore, the surface of the light guide 144 opposite to the light-emitting surface 144-2 faces the interior of the housing 120. The reflector 146 is disposed on the side of the light guide 144 facing away from the light-emitting surface 144-2, and can reflect 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 that is opposite to the light-emitting surface 144-2. The side wall 146-2 is connected to the top wall 146-1, located on the side of the top wall 146-1 near the light guide 144, and distributed around the light guide 144. In this case, 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 a portion of the side surface of the light guide 144. The device consisting of the reflector 146 and the housing 120 can reflect light emitted from surfaces of the light guide 144 other than the light-incident surface 144-1 and the light-emitting surface 144-2, thereby preventing light from escaping from surfaces other than 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 chip, such as an LED chip. The light-emitting element is configured to emit light outward, such as visible light. The light-emitting element may be mounted on and electrically connected to the circuit board. The circuit board may provide power to the light-emitting element.

The multiple 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 radial. The arrows in the figure indicate 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 elements 142-1(a) in the first light source 142(a) shown are merely illustrative. Those skilled in the art should understand that the arrangement and size of the first light-emitting elements 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 diagram of another light source 142 provided according to an embodiment of this 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 power 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) can be light-emitting beads, such as LED beads.

Figure 6 The arrangement, size, and position of the second light-emitting element 142-1(b), third light-emitting element 142-1(c), fourth light-emitting element 142-1(d), fifth light-emitting element 142-1(e), and sixth light-emitting element 142-1(f) in the second light source 142(b) shown are merely illustrative. Those skilled in the art should understand that the arrangement and size of the second light-emitting element 142-1(b), third light-emitting element 142-1(c), fourth light-emitting element 142-1(d), fifth light-emitting element 142-1(e), and 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 earlier, the light-incident surface 144-1 is located at the end of the light-emitting surface 144-2 near the center of the housing 120. This allows the light source 142 to be closer to the center of the housing 120, thereby reducing the size of the light source 142 and improving its integration. Therefore, when the light source 142 is close enough to the center of the housing 120, different light sources 142 can share the same circuit board, such as... Figure 6As shown, this will further enhance the integration of the light source 142, reduce its size, and simultaneously lower costs and simplify manufacturing and installation. Furthermore, since the light-incident surface 144-1 faces the center of the housing 120, different light-emitting elements can be arranged in any direction and position facing the center of the housing 120, further increasing the flexibility of the light-emitting element arrangement. This arrangement allows for different light-incident surfaces 144-1 to have different directions even if the light-emitting surfaces 144-2 of different light guides 144 are in the same direction, thereby further enhancing the concentration of the light source 142 and reducing its size.

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

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

[0070] The light guide 144 has multiple light-emitting guide points 144-31 on its surface 144-3 opposite to the light-emitting surface 144-2. These light-emitting guide points 144-31 can disrupt the incident angle of light, causing the light to diffuse at different angles, making the concentrated light more uniform, thereby improving the uniformity of the light and the light transmission efficiency. One of the multiple light-emitting guide points 144-21 can be a protrusion or a groove. When the light-emitting guide 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 multiple light-emitting guide points 144-31 can be multiple microstructures distributed on the surface 144-3 opposite to the light-emitting surface 144-2. The size of the light-emitting guide points 144-31 can reach the millimeter, micrometer, or even nanometer level. Multiple light-emitting guide points 144-31 can be uniformly or non-uniformly distributed on the surface 144-3 opposite to the light-emitting surface 144-2. The structure and size of the multiple light-emitting guide points 144-31 can be the same or different. This specification does not limit this. The multiple light-emitting guide points 144-31 can be formed by laser engraving, printing, or injection molding of the light guide component 144.

[0071] In the light guide 144, the surface 144-3 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 opposite to the light-emitting surface 144-2 that is farther from the light-incident surface 144-1 is closer to the light-emitting surface 144-2 than the end that is closer to the light-incident surface 144-1. In other words, in the light guide 144-3, the end farther from the light-incident surface 144-1 is closer to the light-emitting surface 144-2. This arrangement allows light to be evenly directed towards the light-emitting surface 144-2, rather than concentrating at the end of the light-emitting surface 144-2 that is farther from the light-incident surface 144-1. This results in a more uniform light emission from the light-emitting surface 144-2, effectively ensuring the equivalent uniformity and consistency of the light-emitting surface 144-2.

[0072] The light-incident surface 144-1 has multiple light-incident guiding points 144-13. These points disrupt the incident angle of light, causing it to diffuse at various angles, resulting in more uniform concentrated light and improved uniformity and light transmission efficiency. The multiple light-incident guiding points 144-13 can be distributed along the width of the light-incident surface 144-1, allowing light to enter the surface evenly along its width. The width of the light-incident surface 144-1 can be perpendicular to the direction of light incidence. One of the multiple light-incident guiding points 144-13 can be a protrusion or a groove. When the light-incident guiding point 144-13 is a protrusion, it can be an arc-shaped protrusion or a protrusion comprising multiple intersecting surfaces (e.g., toothed, conical, or cylindrical). Multiple light-guiding points 144-13 can be multiple microstructures distributed on the light-incident surface 144-1. The size of the light-guiding points 144-13 can reach the millimeter, micrometer, or even nanometer level. The multiple light-guiding points 144-13 can be uniformly or non-uniformly distributed on the light-incident surface 144-1. The structure and size of the multiple light-guiding points 144-13 can be the same or different. This specification does not limit this. The multiple light-guiding points 144-13 can be formed by laser engraving, printing, or injection molding of the light guide 144.

[0073] Figure 8 It shows Figure 3 AA is a cross-sectional view. Figure 8 An installation diagram of the light guide 144, housing 120, and light source 142 is shown. Figure 9 It shows Figure 8 A magnified view of a section I in the middle. (See image below.) Figure 9As shown, the first light guide 144(a) is mounted on the periphery of the housing 120. The light-incident surface 144-1 of the first light guide 144(a) is located at the end of the light-emitting surface 144-2 near 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 reflector 146(a) and the housing 120 together block other surfaces besides 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 back to the light-emitting surface 144-2, thus ensuring that the light can be emitted from the light-emitting surface 144-2 and preventing light leakage.

[0074] Figure 10 It shows Figure 8 A magnified view of a section of the J-shaped area. (See image below.) Figure 10 As shown, the sixth light guide 144(f) is installed inside the housing 120. The light-emitting surface 144-2 of the sixth light guide 144(f) is exposed outside the housing 120 through the mounting hole 123. The light-incident surface 144-1 of the sixth light guide 144(f) is located at the end of the light-emitting surface 144-2 near the center of the housing 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 housing 120 together block other 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 back to the light-emitting surface 144-2, thus ensuring that the light can be emitted from the light-emitting surface 144-2 and preventing light leakage.

[0075] In summary, in the electronic device 100 provided in this embodiment, the light-incident surface 144-1 and the light-emitting surface 144-2 of the light guide 144 are non-parallel surfaces. The light-incident surface 144-1 is located at the end of the light-emitting surface 144-2 near the center of the housing 120 and faces the center of the housing 120. Therefore, the light-incident surface 144-1 is closer to the center of the housing 120 than 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 housing 120. Regardless of the position and orientation of the light-emitting surface 144-2, the light source 142 can be concentrated towards the center of the housing 120, thereby placing the light source 142 in the region at the center of the housing 120, reducing the volume of the light source 142, and increasing the concentration of the light source 142. Meanwhile, since the light-incident surfaces 144-1 all face the center of the housing 120, under complex lighting designs, regardless of the direction and position of the light-emitting surface 144-2, the light source 142 only needs to be opposite to the light-incident surface 144-1, thus making the arrangement of the light source 142 simpler.
