Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an electronic device. Background Technology

[0002] When faced with a dazzling array of electronic devices, users not only need to consider whether the functions of these devices meet their needs, but also the aesthetic appeal of the devices, which is a crucial factor influencing their purchase decision. To enhance the visual appeal of electronic devices, they are often equipped with luminous components, which further enrich their visual impact.

[0003] In related technologies, electronic devices are typically equipped with strip-shaped light-emitting slits, and there are multiple light-emitting elements. These multiple light-emitting elements are arranged at intervals along the extension direction of the light-emitting slits, thereby achieving uniform light emission from the light-emitting slits.

[0004] However, electronic devices require multiple light-emitting elements to ensure uniform light emission brightness across all areas of the light-emitting gap along its extension direction. This necessitates a large number of light-emitting elements, leading to higher energy consumption. Therefore, electronic devices in related technologies have high energy consumption. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device that can solve the technical problem of high energy consumption in electronic devices.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows: This application discloses an electronic device, including: The device housing has an accommodating space and a light-emitting gap communicating with the accommodating space, the light-emitting gap extending along a first direction; A light source assembly is located within the accommodating space. The light source assembly includes a first light-emitting element, a second light-emitting element, and a strip light guide. The strip light guide extends along the first direction, and its two ends opposite to each other along its extension direction are respectively provided with a first light-incident surface and a second light-incident surface. The first light-emitting element is disposed opposite to the first light-incident surface, and the second light-emitting element is disposed opposite to the second light-incident surface. The strip light guide further has a first surface and a second surface arranged opposite to each other along a second direction, the first direction and the second direction intersect each other, the first surface is located on the side of the strip light guide facing the light emission gap, at least a portion of the first surface forms a light emission surface extending along the first direction, and the second surface is provided with a reflective structure arranged opposite to the light emission surface; The light emitted by the first light-emitting element and the second light-emitting element enters the strip light guide through their corresponding light-incident surfaces, and exits from the light-exit gap after passing through the reflection structure and the light-exit surface.

[0007] In this embodiment, the first and second light-emitting elements are located at both ends of the extending direction of the strip light guide, so the incident light from the light source assembly enters from both ends of the strip light guide. A reflective structure is provided on the side opposite to the light-emitting surface to guide the light along the extending direction of the strip light guide, thereby improving the uniformity of the emitted light. The electronic device disclosed in this application only has light-emitting elements at both ends of the strip light guide, thereby reducing the number of light-emitting elements and effectively reducing the energy consumption of the electronic device.

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0013] Please refer to Figures 1 to 16 This application discloses an electronic device, which includes a device housing 100 and a light source assembly 200.

[0014] The device housing 100 provides mounting space for other components of the electronic device. The device housing 100 has a receiving space 101 and a light-emitting gap 102 communicating with the receiving space 101. The receiving space 101 of the device housing 100 is connected to the external environment through the light-emitting gap 102. The receiving space 101 can be used to install functional components of the electronic device, such as a motherboard, camera module, etc.

[0015] The light emission gap 102 extends along the first direction X. In this application, the light emission gap 102 extends along the first direction X, therefore the light emission gap 102 is a strip-shaped structure extending along the first direction X. Here, the first direction X can be the length direction or the width direction of the device housing 100, or it can be a direction extending circumferentially along the device housing 100.

[0016] The aforementioned light-emitting gap 102 can be a straight strip or an arc-shaped gap. Therefore, the light-emitting gap 102 here can be a straight strip structure extending along the first direction X, or an arc-shaped strip structure extending approximately along the first direction X. (See attached document for details.) Figure 2 As shown, the light-emitting gap 102 is an arc-shaped strip structure that extends approximately along the first direction X. At this time, the light-emitting gap 102 has a certain curvature.

[0017] The light source assembly 200 is located within the accommodating space 101. This light source assembly 200 can be a breathing light or ambient light for an electronic device; the specific application of the light source assembly 200 is not limited in this application. The light emitted by the light source assembly 200 can be emitted outside the electronic device through the light emission gap 102, thereby forming a strip-shaped light effect on the electronic device to enhance its appearance. The light source assembly 200 includes a first light-emitting element 210, a second light-emitting element 220, and a strip-shaped light guide 230, which is a light transmission component. The strip-shaped light guide 230 extends along a first direction X. At this time, the strip-shaped light guide 230 extends along the extension direction of the light emission gap 102, so that the strip-shaped light guide 230 can cover the light emission gap 102, thereby ensuring that all areas of the light emission gap 102 along its extension direction can emit light, avoiding situations where the two ends of the light emission gap 102 do not emit light or have low light intensity.

[0018] The strip light guide 230 has a first light-incident surface 2301 and a second light-incident surface 2302 at its two opposite ends along its extension direction. A first light-emitting element 210 is disposed opposite to the first light-incident surface 2301. A second light-emitting element 220 is disposed opposite to the second light-incident surface 2302. In this case, the end faces of both ends of the strip light guide 230 along its extension direction serve as light-incident surfaces, and light rays are incident into the strip light guide 230 from the end faces of both ends. The first light-emitting element 210 and the second light-emitting element 220 can be LED (Light Emitting Diode) lamps, high-pressure sodium lamps, metal halide lamps, etc. Of course, the first light-emitting element 210 and the second light-emitting element 220 can also have other structures, which are not limited herein.

[0019] The strip light guide 230 also has a first surface 2303 and a second surface 2304 disposed opposite to each other along the second direction Y, where the first direction X and the second direction Y intersect. Since the first direction X is the extending direction of the strip light guide 230, the second direction Y can be the radial direction, width direction, or height direction of the strip light guide 230. Therefore, the first surface 2303 and the second surface 2304 are both part of the outer peripheral surface of the strip light guide 230. Of course, the second direction Y can also be other directions intersecting the first direction X, which is not limited in this application. The strip light guide 230 and the light emission gap 102 can be arranged along the second direction Y. Of course, the strip light guide 230 and the light emission gap 102 can also be arranged along other directions that intersect both the second direction Y and the first direction X, which is not limited in this application.

[0020] The first surface 2303 is located on the side of the strip light guide 230 facing the light emission gap 102. At least a portion of the first surface 2303 forms a light emission surface 23031 extending along the first direction X. The light emission surface 23031 is used for emitting light from the strip light guide 230. Therefore, the side where the first surface 2303 is located is the light emission side of the strip light guide 230. The light emission surface 23031 extends along the first direction X. At this time, the light emission surface 23031 is a strip-shaped surface extending along the first direction X. At this time, the extension direction of the light emission surface 23031 is the same as the extension direction of the strip light guide 230. The light emission surface 23031 can be a straight strip-shaped plane or a strip-shaped arc surface. Therefore, the light emission surface 23031 here can be a straight strip surface extending along the first direction X or an arc-shaped strip surface extending approximately along the first direction X. As shown in the appendix to this application... Figure 7 As shown, the light-emitting surface 23031 is an arc-shaped strip extending approximately along the first direction X. At this time, the light-emitting surface 23031 has a certain curvature.

[0021] In this embodiment of the application, the first surface 2303 is a light-emitting surface 23031, that is, the first surface 2303 is a light-emitting surface 23031, or a portion of the first surface 2303 is a light-emitting surface 23031. The first surface 2303 can also extend along the first direction X, and the extension direction of the first surface 2303 is the same as the extension direction of the light-emitting surface 23031.

[0022] The second surface 2304 is provided with a reflective structure 23041 disposed opposite to the light-emitting surface 23031. In this case, the reflective structure 23041 can be directly opposite the light-emitting surface 23031, that is, along the second direction Y, the projected area of ​​the reflective structure 23041 coincides with the projected area of ​​the light-emitting surface 23031. Alternatively, the projected area of ​​the reflective structure 23041 can be larger than the projected area of ​​the light-emitting surface 23031, and the reflective structure 23041 can cover the entire light-emitting surface 23031.

[0023] In the specific operation process, the light emitted by the first light-emitting element 210 and the second light-emitting element 220 can enter the strip light guide 230 through their corresponding light-incident surfaces, and then exit from the light-emitting gap 102 after passing through the reflective structure 23041 and the light-emitting surface 23031. Specifically, the light emitted by the first light-emitting element 210 enters through the first light-incident surface 2301, and the light propagates within the strip light guide 230 along the direction from the first light-incident surface 2301 to the second light-incident surface 2302. During the propagation process, the reflective structure 23041 can reflect the light to the side where the light-emitting surface 23031 is located. Similarly, the light emitted by the second light-emitting element 220 enters through the second light-incident surface 2302, and the light propagates within the strip light guide 230 along the direction from the second light-incident surface 2302 to the first light-incident surface 2301. During the propagation process, the reflective structure 23041 can reflect the light to the side where the light-emitting surface 23031 is located.

[0024] In the embodiments disclosed in this application, the first light-emitting element 210 and the second light-emitting element 220 are located at both ends of the extending direction of the strip light guide 230. Therefore, the incident light from the light source assembly 200 enters from both ends of the strip light guide 230. A reflective structure 23041 is provided on the side opposite to the light-emitting surface 23031 to guide the light in the extending direction of the strip light guide 230, thereby improving the uniformity of the emitted light. The electronic device disclosed in this application only provides light-emitting elements at both ends of the strip light guide 230. The strip light guide 230 adopts a double-end incident layout, and only two light-emitting elements are needed to achieve overall light guiding in the extending direction of the strip light guide 230. Compared with the arrangement of multiple light-emitting elements along the extending direction of the light-emitting gap 102, this application significantly reduces the number of light-emitting elements used, thereby avoiding the risk of the electronic device supplying power to multiple light-emitting elements at the same time. Therefore, it can effectively reduce the energy consumption of the electronic device and help improve the battery life of the electronic device.

[0025] Furthermore, this application significantly reduces the number of light-emitting components used, which helps to lower the cost of electronic devices and overall material costs. It also reduces the number of alignment and mounting points between multiple light-emitting components, simplifying the assembly process and improving production yield.

[0026] In this application, when light rays incident from both ends are propagated along the extension direction of the strip light guide 230, they will naturally attenuate due to material absorption and scattering, resulting in lower light intensity in the middle compared to the two ends. The reflective structure 23041 can reflect the light rays from the side of the strip light guide 230 away from the light-emitting surface 23031 back to the light guide path, supplementing the luminous flux in the middle region, thereby making the brightness at both ends similar to that in the middle, and thus improving the uniformity of light emission. In addition, the reflective structure 23041 can be designed with specific textures or curvatures to make the reflected light rays strike the light-emitting surface 23031 at a more uniform angle, avoiding the formation of local bright spots due to direct light hitting the light-emitting surface 23031, while reducing disordered reflection loss of light inside the strip light guide 230. Furthermore, the recycling of light emitted by the reflective structure 23041 towards the side away from the light-emitting surface 23031 can increase the overall light energy density of the strip light guide 230, further reduce the light intensity difference in different areas of the light-emitting surface 23031, and thus further improve the light utilization efficiency.

[0027] In addition, reducing the number of light-emitting components also reduces the number of heat sources inside electronic devices, thus improving the heat dissipation performance of electronic devices.

[0028] In the embodiments disclosed in this application, the double-end incident light combined with the reflection structure 23041 can recover and reuse the escaping light rays within the strip light guide 230, improving the light utilization rate. While meeting the target brightness of the light-emitting surface 23031, there is no need to increase the driving power of the light-emitting element to compensate for light loss. Compared to the solutions in the prior art, the load on a single light-emitting element is lower, thus further reducing the energy consumption of redundant light-emitting elements and further reducing overall energy consumption, thereby further extending the battery life of the electronic device.

[0029] In the above scheme, the entire area of ​​the second surface 2304 can be used for light emission, so the second surface 2304 is the light emission surface 23031.

[0030] In another embodiment, the strip light guide 230 may include a first light mixing segment 231, a light guide segment 232, and a second light mixing segment 233 that are smoothly connected sequentially along a first direction X. In this case, the first light mixing segment 231 and the second light mixing segment 233 are located at both ends of the light guide segment 232. The smooth connection here can be understood as the cross-sectional area at the junction of the first light mixing segment 231 and the light guide segment 232 being the same, and the cross-sectional area at the junction of the second light mixing segment 233 and the light guide segment 232 being the same, thereby achieving a smooth transition. The end face of the first light mixing segment 231 facing away from the light guide segment 232 is the first light incident surface 2301. The end face of the second light mixing segment 233 facing away from the light guide segment 232 is the second light incident surface 2302. The light emitting surface 23031 and the reflection structure 23041 are both disposed on the light guide segment 232. At this time, the first surface 2303 may include a first sub-surface, a second sub-surface, and a third sub-surface. The first sub-surface is located in the first light mixing section 231, the second sub-surface is located in the light guiding section 232, and the third sub-surface is located in the second light mixing section 233. The light emitting surface 23031 is disposed on the second sub-surface located in the middle, so the middle region of the first surface 2303 is provided with the light emitting surface 23031. Similarly, the second surface 2304 includes a fourth sub-surface, a fifth sub-surface, and a sixth sub-surface. The fourth sub-surface is located on the first light mixing section 231, the fifth sub-surface is located on the light guiding section 232, and the sixth sub-surface is located on the second light mixing section 233. At this time, the reflection structure 23041 is disposed on the fifth sub-surface located in the middle, so the middle region of the second surface 2304 is provided with the reflection structure 23041.

[0031] In the specific light-emitting process, the light emitted by the first light-emitting element 210 enters the first light-mixing section 231 through the first light-incident surface 2301, then enters the light-guiding section 232 through the first light-mixing section 231, and exits through the light-guiding section 232. Similarly, the light emitted by the second light-emitting element 220 enters the second light-mixing section 233 through the second light-incident surface 2302, then enters the light-guiding section 232 through the second light-mixing section 233, and exits through the light-guiding section 232.

[0032] In this design, the two ends of the strip light guide 230 are reserved with light mixing sections. After the light enters the light mixing section, it is mixed before being transmitted to the light guide section 232 for emission. The light mixing section can mix the light, thereby avoiding the problem of large color distortion in the emitted light, and thus improving the light mixing uniformity of the light source assembly 200. In addition, the first light mixing section 231 and the second light mixing section 233 can quickly overflow and attenuate the light emitted by the light source that does not meet the total internal reflection condition, thereby filtering out the light that does not meet the total internal reflection condition, so that the light entering the light guide section 232 can all be total internal reflection light, thereby improving the light distribution efficiency of the reflective structure 23041.

[0033] In the above scheme, the cross-sectional areas of the first light mixing segment 231 and the second light mixing segment 233 along the first direction X can be the same, that is, the cross-sectional areas of the first light mixing segment 231 and the second light mixing segment 233 are equal and constant.

[0034] Furthermore, in this application, both the first light-mixing segment 231 and the second light-mixing segment 233 can be wedge-shaped structures. Along the first direction X, the cross-sectional area of ​​the first light-mixing segment 231 and the second light-mixing segment 233 gradually decreases. Here, the cross-section refers to the cross-section perpendicular to the first direction X.

[0035] In this design, both the first light-mixing segment 231 and the second light-mixing segment 233 are variable cross-section structures. The variable cross-section structure increases the number of reflections of light within the first and second light-mixing segments 231 and 233. Because the first and second light-mixing segments 231 and 233 of the strip light guide 230 can increase the number of light reflections, the distance between them can be set shorter, thereby effectively increasing the actual size of the light effect formed by the strip light guide 230.

[0036] Compared to the first and second light mixing segments 231 and 233 with constant cross-sections in the strip light guide 230, the first and second light mixing segments 231 and 233 of the strip light guide 230 have a shorter distance between them, provided that the length of the light emitting surface 23031 is the same. This is beneficial for reducing the length of the strip light guide 230, thereby reducing the overall volume of the light source assembly 200, and further reducing the space occupied by the light-emitting assembly 200 in the internal space of the electronic device. Therefore, the structure of the electronic device can be further optimized.

[0037] In the above scheme, the end face of the first light mixing segment 231 facing the first light-emitting element 210 is smaller than the end face of the first light mixing segment 231 connected to the light guide segment 232. At this time, the cross-sectional area of ​​the light-incident end of the first light mixing segment 231 is smaller than the cross-sectional area of ​​the light-exiting end of the first light mixing segment. Here, the light-incident end of the first light mixing segment 231 refers to the end where the first light-incident surface 2301 is located, while the light-exiting end of the first light mixing segment 231 refers to the end connected to the light guide segment 232. The first light mixing segment 231 has a gradually expanding structure in the direction from the first light-incident surface 2301 to its second light-incident surface 2302. That is, the closer the first light mixing segment 231 is to the light guide segment 232, the larger its cross-sectional area. The end face where the first light mixing segment 231 connects to the light guide segment 232 is its largest cross-sectional area.

[0038] Similarly, the end face of the second light-mixing segment 233 facing the second light-emitting element 220 is smaller than the end face of the second light-mixing segment 233 connected to the light guide segment 232. At this time, the cross-sectional area of ​​the light-incident end of the second light-mixing segment 233 is smaller than the cross-sectional area of ​​the light-exiting end of the second light-mixing segment 233. Here, the light-incident end of the second light-mixing segment 233 refers to the end where the second light-incident surface 2302 is located, while the light-exiting end of the second light-mixing segment 233 refers to the end connected to the light guide segment 232. The second light-mixing segment 233 has a gradually expanding structure in the direction from the second light-incident surface 2302 to its first light-incident surface 2301. That is, the closer the second light-mixing segment 233 is to the light guide segment 232, the larger its cross-sectional area. The end face where the second light-mixing segment 233 connects to the light guide segment 232 is its largest cross-sectional area.

[0039] In another alternative scheme, the end face of the first light-mixing segment 231 facing the first light-emitting element 210 is larger than the end face of the first light-mixing segment 231 connected to the light guide segment 232. In this case, the cross-sectional area of ​​the light-incident end of the first light-mixing segment 231 is larger than the cross-sectional area of ​​the light-exiting end of the first light-mixing segment 231. Here, the light-incident end of the first light-mixing segment 231 refers to the end where the first light-incident surface 2301 is located, while the light-exiting end of the first light-mixing segment 231 refers to the end connected to the light guide segment 232. The first light-mixing segment 231 has a tapered structure in the direction from the first light-incident surface 2301 to its second light-incident surface 2302. That is, the closer the first light-mixing segment 231 is to the light guide segment 232, the smaller its cross-sectional area. The end face where the first light-mixing segment 231 connects to the light guide segment 232 is its smallest cross-sectional area.

[0040] In this design, the end area of ​​the first light mixing segment 231 facing away from the light guide segment 232 is relatively large. This results in the strip light guide 230 having a larger first light-incident surface 2301, allowing the light emitted by the first light-emitting element 210 to be coupled into the strip light guide 230 as much as possible. This increases the light coupling area of ​​the strip light guide 230, thus improving the light utilization efficiency of the light source assembly 200 and increasing the luminous intensity. Simultaneously, the larger size of the first light-incident surface 2301 prevents relative misalignment between the light-emitting element and the strip light guide 230, reducing light leakage caused by assembly misalignment and thus improving the problem of color distortion in the emitted light.

[0041] Similarly, the end face of the second light-mixing segment 233 facing the second light-emitting element 220 is larger than the end face of the second light-mixing segment 233 connected to the light guide segment 232. At this time, the cross-sectional area of ​​the light-incident end of the second light-mixing segment 233 is larger than the cross-sectional area of ​​the light-exiting end of the second light-mixing segment 233. Here, the light-incident end of the second light-mixing segment 233 refers to the end where the first light-incident surface 2301 is located, while the light-exiting end of the first light-mixing segment 231 refers to the end connected to the light guide segment 232. The second light-mixing segment 233 has a tapered structure in the direction from the second light-incident surface 2302 to its first light-incident surface 2301. That is, the closer the second light-mixing segment 233 is to the light guide segment 232, the smaller its cross-sectional area. The end face where the second light-mixing segment 233 connects to the light guide segment 232 is its smallest cross-sectional area.

[0042] In this scheme, the end area of ​​the second light mixing section 233 away from the light guide section 232 is relatively large, which makes the strip light guide 230 have a large second light incident surface 2302. This allows the light emitted by the second light emitting element 220 to be coupled into the strip light guide 230 as much as possible, thereby increasing the light coupling area of ​​the strip light guide 230. Therefore, it is beneficial to improve the light utilization efficiency of the light source assembly 200, thereby increasing the luminous intensity.

[0043] In this application, the wedge-shaped structure design of the first light mixing section 231 and the second light mixing section 233, as well as the enlarged light-incident end size, ensure that the light from the light-emitting units located at the edge of the light-emitting element can be coupled into the strip light guide 230, thereby reducing the deviation between the actual mixed light effect color and the preset light effect color, and thus reducing the deviation of the light emission color of the light source assembly 200, thereby improving the light emission effect of the light source assembly 200.

[0044] In the above scheme, the dimensions of the first mixing segment 231 and the second mixing segment 233 along the first direction X are as shown in the attached figure. Figure 1 As shown in the figure, the range of a can be between 2 mm and 8 mm. Specifically, a can be 5.13 mm.

[0045] In one embodiment, the area of ​​the cross-section of the light guide segment 232 perpendicular to the first direction X is constant along the extension direction of the light guide segment 232. Along the extension direction of the light guide segment 232, the cross-sectional area dimensions of each local area of ​​the light guide segment 232 are the same.

[0046] In one embodiment, both the first light-emitting element 210 and the second light-emitting element 220 include a first RGB light source 211 and a second RGB light source 212 arranged side-by-side along a first arrangement direction. Here, the first arrangement direction refers to the arrangement direction of the two RGB light sources. The first RGB light source 211 is composed of red light-emitting units, green light-emitting units, and blue light-emitting units arranged sequentially along a second arrangement direction. Here, the second arrangement direction refers to the arrangement direction of multiple light-emitting units of different colors within each RGB light source.

[0047] Similarly, the second RGB light source 212 is also composed of red light-emitting units, green light-emitting units, and blue light-emitting units arranged sequentially along the second arrangement direction. At this time, along the first arrangement direction, the red light-emitting units of the first RGB light source 211 and the second RGB light source 212 are arranged side-by-side, the green light-emitting units of the second RGB light source 212 are arranged side-by-side, and the blue light-emitting units of the first RGB light source 211 and the second RGB light source 212 are arranged side-by-side. The first and second arrangement directions intersect. The first arrangement direction can be along the aforementioned second direction Y, and the second arrangement direction can be along a third direction Z that intersects both the first and second directions X and Y. The first direction X can be the length direction of the strip light guide 230, the second direction Y can be the width direction of the strip light guide 230, and the third direction Z can be the height or thickness direction of the strip light guide 230. Of course, the first and second arrangement directions can also be other directions, and this application does not impose any limitations.

[0048] In the above scheme, the coupling ends of the first RGB light source 211 and the second RGB light source 212 with the strip light guide 230 are prone to misalignment. Since the red light emitting unit and the blue light emitting unit are located on both sides, the misalignment may cause some of the light from the red light emitting unit or the blue light emitting unit to fail to couple into the strip light guide 230. This is especially noticeable when the strip light guide 230 is thin, which ultimately causes the color of the light effect area to deviate from the design expectation, i.e., the production is too red or too blue.

[0049] Based on this, in another optional embodiment, the first RGB light source 211 is composed of red light-emitting units, green light-emitting units, and blue light-emitting units arranged sequentially along a second arrangement direction. The second RGB light source 212 is composed of blue light-emitting units, green light-emitting units, and red light-emitting units arranged sequentially along the second arrangement direction. In this case, the arrangement order of the light-emitting units in the first RGB light source 211 is the reverse of the arrangement order of the light-emitting units in the second RGB light source 212. Specifically, along the first arrangement direction, the red light-emitting units of the first RGB light source 211 and the blue light-emitting units of the second RGB light source 212 are arranged side by side, the green light-emitting units of the second RGB light source 212 are arranged side by side, and the blue light-emitting units of the first RGB light source 211 and the red light-emitting units of the second RGB light source 212 are arranged side by side.

[0050] In this design, two RGB light sources are placed at the light-incident surface, and these two RGB light sources are positioned opposite each other, resulting in an opposite arrangement of the light-emitting units. Therefore, when the light-emitting component and the strip light guide 230 are misaligned during assembly, both red and blue light are lost simultaneously, thus avoiding the risk of the emitted light color being too red or too blue.

[0051] Furthermore, the light-emitting units of the first RGB light source 211 and the second RGB light source 212 are arranged in opposite directions. When arranged side by side along the first arrangement direction, the same-color light-emitting units of adjacent light sources will not be concentrated, which can avoid the risk of color unevenness caused by excessive intensity of a single color light in local areas. At the same time, the intersecting first and second arrangement directions allow the light-emitting units to form a staggered layout in the two-dimensional plane, expanding the radiation coverage of monochromatic light and reducing the blind zone of light mixing. In addition, the spatial distribution of light-emitting units of different colors is closer to a uniform and discrete state, and the light can be fully superimposed without long-distance diffusion during propagation, thereby effectively reducing the color spots, stripes and other uneven mixing phenomena that can be perceived by the naked eye.

[0052] In the above scheme, both the first light-emitting element 210 and the second light-emitting element 220 are equipped with two RGB light sources. Dual light source coupling can also significantly increase the brightness of the final effect and improve the light intensity.

[0053] In this application, by using the wedge-shaped structure design of the first mixing section 231 and the second mixing section 233, expanding the size of the light-incident end, and arranging the light-emitting units of different colors of the two RGB light sources in the direction of light emission, the deviation between the actual mixed light effect color and the preset light effect color can be effectively reduced, thereby reducing the deviation of the light emission color of the light source component 200 and thus improving the light emission effect of the light source component 200.

[0054] In the above scheme, along the direction from the first light-incident surface 2301 to the second light-incident surface 2302, the size of the first light-mixing segment 231 gradually decreases along the third direction Z; wherein, the third direction Z intersects both the first direction X and the second direction Y. For example, the first direction X can be the length direction of the strip light guide 230, the second direction Y can be the width direction of the strip light guide 230, and the third direction Z can be the height or thickness direction of the strip light guide 230. Along the direction from the second light-incident surface 2302 to the first light-incident surface 2301, the size of the second light-mixing segment 233 gradually decreases along the third direction Z.

[0055] The dimensions of the first light mixing segment 231 and the second light mixing segment 233 along the second direction Y are equal to the dimensions of the light guiding segment 232 along the second direction Y. At this time, the first sub-surface, the second sub-surface, and the third sub-surface are flush, and the fourth sub-surface, the fifth sub-surface, and the sixth sub-surface are flush.

[0056] In this scheme, the dimensions of the first light mixing section 231 and the second light mixing section 233 differ from those of the light guide section 232 only in the third direction Z, thus reducing the manufacturing difficulty and consequently reducing the manufacturing difficulty of the strip light guide 230.

[0057] like Figure 8 As shown, the dimension of the end face of the first light mixing segment 231 and the second light mixing segment 233 opposite to the light guide segment 232 along the third direction Z can be L, and the dimension of the light guide segment 232 along the third direction Z can be P. In this case, L can be 1.4 mm and P can be 0.7 mm. Of course, L and P can also be other values, which are not limited in this application.

[0058] In one embodiment, the reflective structure 23041 may include a plurality of reflective grooves formed on the second surface 2304, and the plurality of reflective grooves may be arranged in an array on the second surface 2304. This can also be understood as the reflective grooves being grooved structures provided on the second surface 2304.

[0059] In one embodiment, the reflective structure 23041 may include a plurality of first reflective protrusions 23041a protruding from the second surface 2304. The plurality of first reflective protrusions 23041a are arranged along a first direction X. These plurality of first reflective protrusions 23041a can be understood as protruding tooth-shaped structures. In this scheme, the first reflective protrusions 23041a are provided on the second surface 2304, and the first reflective protrusions 23041a protrude in a direction away from the first surface 2303. Compared to a etched structure, providing protruding first reflective protrusions 23041a on the second surface 2304 reduces manufacturing difficulty and allows for better control of the reflection angle of the first reflective protrusions 23041a, thus resulting in better light control. Furthermore, the first reflective protrusions 23041a effectively increase the dimension of the strip light guide 230 along the second direction Y, thereby improving the strength of the strip light guide 230.

[0060] Furthermore, such as Figure 15 and Figure 16 As shown, the first reflective protrusion 23041a extends along the third direction Z, and the size of the first reflective protrusion 23041a in the third direction Z decreases from the middle position of the strip light guide 230 to both ends; wherein, the third direction Z intersects with both the first direction X and the second direction Y.

[0061] In this design, the light guide segment 232 has a stronger luminous efficiency closer to its end along its extension direction. Therefore, the size of the first reflective protrusion 23041a in the third direction Z needs to be reduced to decrease the light output brightness in that area. Conversely, the light guide segment 232 transmits less light further away from its end along its extension direction. Therefore, the size of the first reflective protrusion 23041a in the third direction Z needs to be increased to increase the amount of light reflection and thus improve the light output brightness in that area. Therefore, different sizes of first reflective protrusions 23041a are provided in different areas of the light guide segment 232, thereby further improving the light output uniformity of the electronic device.

[0062] In the above scheme, the dimensions of the first reflective protrusion 23041a in the third direction Z are as follows: Figure 16 As shown in w in the diagram. The dimension of the first reflective protrusion 23041a in the third direction Z can be the length of the first reflective protrusion 23041a, therefore the length of the first reflective protrusion 23041a decreases from the middle position of the strip light guide 230 towards both ends. The dimension of the first reflective protrusion 23041a along the first direction X can be the width of the first reflective protrusion 23041a, the width of the first reflective protrusion 23041a increases from the middle position of the strip light guide 230 towards both ends. Alternatively, the width of the first reflective protrusion 23041a can be constant.

[0063] In one specific embodiment, as shown in Table 1 below, Table 1 describes the variation parameters of the dimension w of the first reflective protrusion 23041a in the third direction Z as a function of the extension direction of the strip light guide 230.

[0064] Table 1

[0065] In Table 1, 0% indicates the connection position between the light guide segment 232 and the first light mixing segment 231, such as... Figure 15 The position shown as H1 in Table 1. 50% in Table 1 indicates the middle position of light guide segment 232, as shown... Figure 15 The position shown is H2 in Table 1. 100% in Table 1 indicates the connection position between the light guide section 232 and the second light mixing section 233, as shown below. Figure 15 The position is shown as H3 in the diagram. Of course, the dimension w of the first reflective protrusion 23041a in the third direction Z is not limited to the above value. The value of w can also fluctuate within a range of ±0.05, which is not limited in this application.

[0066] In the above scheme, the value of w is the largest at the 50% position, and it can be equal to the dimension of the strip light guide 230 in the third direction Z. This can be understood as w being equal to the thickness of the strip light guide 230 at the 50% position.

[0067] In another alternative embodiment, the first reflective protrusion 23041a may include a first plane 23041a1, a first arcuate surface 23041a2, and a second plane 23041a3 connected sequentially along a first direction X. In the direction from the first surface 2303 to the second surface 2304, the distance between the first plane 23041a1 and the second plane 23041a3 gradually decreases, and the first arcuate surface 23041a2 is an arcuate convex surface protruding in a direction away from the first surface 2303.

[0068] In this design, the combination of the first plane 23041a1, the second plane 23041a3, and the convex first arc surface 23041a2 allows for segmented reflection and guidance of light. The planar portion achieves directional reflection, while the arc surface portion achieves uniform diffusion of light, effectively improving the consistency of light emission in the target direction and reducing stray light interference. Furthermore, the design of gradually decreasing planar spacing from the first surface 2303 to the second surface 2304 compresses the light reflection path and reduces energy loss.

[0069] In addition, the integrated double-plane arc-shaped protrusion structure can be cast in one mold without additional splicing or processing, reducing the complexity of the production process.

[0070] like Figure 10As shown, the width of the first plane 23041a1 and the width of the second plane 23041a3 are both possible. Specifically, the width of the first plane 23041a1 and the width of the second plane 23041a3 are both as shown... Figure 10 As shown in n. The distance between the side of the first plane 23041a1 away from the first arc surface 23041a2 and the side of the second plane 23041a3 away from the first arc surface 23041a2 is as follows. Figure 10 As shown in m. The angle between the line connecting the edge of the first plane 23041a1 on the side opposite to the first arc surface 23041a2 and the edge of the second plane 23041a3 on the side opposite to the first arc surface 23041a2, and the first plane 23041a1 and the second plane 23041a3 is as follows. Figure 10 As shown in the figure, 'r' can be understood as the tilt angle of the first plane 23041a1 and the second plane 23041a3 relative to the second surface 2304. In one embodiment, 'm' can be between 0.2 mm and 0.4 mm. 'n' can be between 0.1 mm and 0.3 mm. 'R' can be between 29° and 69°. Specifically, 'm' can be 0.34 mm, 'n' can be 0.225 mm, and 'r' can be 49°. Of course, this application only illustrates one feasible embodiment and is not intended to limit the specific values ​​of this application.

[0071] Furthermore, any two adjacent first reflective protrusions 23041a can be connected by a second arc surface 23041b, which can be an arc-shaped concave surface that is recessed toward the first surface 2303.

[0072] In this design, the recessed second arc surface 23041b can converge or guide the light incident on the gap of the first reflective protrusion 23041a, avoiding the formation of light blind spots or stray light scattering at the gap, thus significantly improving the overall light utilization rate. In addition, the transition structure of the second arc surface 23041b can disperse the stress concentration at the connection of the first reflective protrusion 23041a, reducing the risk of mold wear and cracking during casting and improving the mechanical stability of the structure.

[0073] In the above scheme, the equipment housing 100 can be a one-piece housing.

[0074] In another embodiment, the device housing 100 may include a first housing 110 and a second housing 120, which may be stacked along a third direction Z. The first housing 110 and the second housing 120 form the aforementioned receiving space 101 and light-emitting gap 102. In this design, the separate configuration of the device housing 100 facilitates the assembly of internal components, thereby simplifying the assembly process of the electronic device.

[0075] Furthermore, the first housing 110 has a first sidewall 111, which can form a light-emitting gap 102 with the second housing 120. The first sidewall 111 can be disposed opposite to the light-emitting surface 23031. The light emitted from the light-emitting surface 23031 can be reflected by the first sidewall 111 and then emitted from the light-emitting gap 102.

[0076] In this design, the first sidewall 111 is positioned opposite to the light-emitting surface 23031. The light emitted from the light-emitting surface 23031 needs to be reflected by the first sidewall 111 before being emitted. Therefore, the first sidewall 111 serves as a reflective surface to reflect light beyond the device housing 100. Thus, when the light source assembly 200 is not activated, the structural differences between the first sidewall 111 and other areas of the first housing 110 are minimal. These differences can be aesthetic differences such as shape or color. Therefore, this application further visually conceals the light-emitting position of the device housing 100, resulting in a more consistent appearance of the device housing 1100 and thus improving the overall aesthetics of the electronic device.

[0077] In the above scheme, the first housing 110 has a first groove on the side facing the second housing 120, and at least a portion of the second housing 120 is located within the first groove. In this case, the first sidewall 111 can be at least a portion of the sidewall of the first groove. The light-emitting gap 102 in this application can be formed by at least a portion of the sidewall of the first groove and at least a portion of the outer peripheral surface of the second housing 120.

[0078] In another alternative embodiment, the first sidewall 111 may be provided with multiple second reflective protrusions 1111a, which are arranged at intervals on the first sidewall 111. In this case, a portion of the first sidewall 111 has the second reflective protrusions 1111a, while another portion does not. The reflection angle and intensity of light on the area of ​​the first sidewall 111 with the second reflective protrusions 1111a differ from those on the area without the second reflective protrusions 1111a. Therefore, when incident light from the same direction strikes different positions on the first sidewall 111, the direction and brightness of the emitted light differ significantly because the reflection intensity and angle are different between the areas with and without the second reflective protrusions 1111a. Thus, when dynamically observed from different angles, the difference in the effect of the different second reflective protrusions 1111a can be perceived, creating a shimmering light effect and further improving the optical performance of the electronic device.

[0079] Figure 5The dashed line A represents the light reflected from the area on the first sidewall 111 where the second reflective protrusion 1111a is provided. The dashed line B represents the light reflected from the area on the first sidewall 111 where the second reflective protrusion 1111a is not provided.

[0080] In another alternative embodiment, the first sidewall 111 may have a first edge 111a and a second edge 111b disposed opposite to each other. The first edge 111a may be located on the side of the first sidewall 111 facing the strip light guide 230, where the first edge 111a is located on the side facing the receiving space 101, while the second edge 111b is located on the side facing the external environment, so the second edge 111b is an exposed edge.

[0081] The first sidewall 111 may be provided with multiple reflection groups 1111, and the multiple reflection groups 1111 may be arranged at intervals along the first direction X. Each reflection group 1111 may include multiple second reflection protrusions 1111a, and the second reflection protrusions 1111a in each reflection group 1111 may be arranged at intervals along the direction from the first edge 111a to the second edge 111b.

[0082] In this scheme, multiple second reflective protrusions 1111a are arranged in an array on the first sidewall 111, so that the entire surface of the first sidewall 111 can achieve a shimmering light effect, further improving the appearance performance of the electronic device.

[0083] Furthermore, multiple reflector groups 1111 are equidistantly arranged along the first direction X. At this time, the distance between any two adjacent reflector groups 1111 is equal. The distance between any two adjacent reflector groups 1111 can be understood as the center distance or the adjacent side distance between any two reflector groups 1111.

[0084] The second reflective protrusions 1111a in each reflective group 1111 can be equidistantly arranged, in which case the distance between any two adjacent second reflective protrusions 1111a in each reflective group 1111 can be equal. Similarly, the distance between any two adjacent second reflective protrusions 1111a can be the center distance between the two second reflective protrusions 1111a or the adjacent side distance.

[0085] In this scheme, each reflection group 1111 and the second reflection protrusion 1111a within each reflection group 1111 are equidistantly distributed, which enables the incident light to form a uniform optical path difference on the reflection path, avoids local light superposition or absence, and improves the uniformity and consistency of the emitted light.

[0086] Furthermore, the distance between two adjacent reflective groups 1111 is the first distance. The distance between two adjacent second reflective protrusions 1111a in each reflective group 1111 can be the second distance, which can be less than the first distance.

[0087] In this design, the small-spaced arrangement of the second reflective protrusions 1111a within the reflective group 1111 increases the light reflection contact area, thereby shortening the local optical path and improving the light convergence efficiency or diffuse reflection uniformity. Meanwhile, the large spacing between the reflective groups 1111 provides a buffer space for the optical path, preventing crosstalk between reflected light from different reflective groups 1111 and ensuring the accuracy of the light output direction.

[0088] First distance as Figure 12 As shown by 'v', the first distance can be from 2mm to 4mm, specifically 3.5mm. Of course, the first distance can also be other values, which are not limited in this paper. The second distance is as follows... Figure 13 As shown in u in the figure. The second distance can be between 0.2mm and 0.4mm, specifically 0.3mm. Of course, the second distance can also be other values, which are not limited in this article.

[0089] In the above scheme, the second reflective protrusion 1111a can be a cylindrical, prism or other structure.

[0090] In one alternative design, the second reflective protrusion 1111a can be a tapered structure along the direction away from the first sidewall 111. In this case, the further the second reflective protrusion 1111a is from the first sidewall 111, the smaller its cross-sectional area. In this design, the tapered structure of the second reflective protrusion 1111a can provide directional guidance and reflection of the incident light, reducing diffuse reflection loss on the sidewall of the second reflective protrusion 1111a and improving the concentration and directionality of the emitted light. Simultaneously, the tapered structure can prevent light blockage between adjacent second reflective protrusions 1111a, optimizing the uniformity of light emission.

[0091] Furthermore, the second reflective protrusion 1111a can be a triangular prism structure, with its two base surfaces arranged along the first direction X, and one side surface of the triangular prism structure facing the first sidewall 111 and connected to it. In this design, the triangular prism structure is simple and has good performance in adjusting the reflection angle, thus optimizing the light output performance.

[0092] In another alternative embodiment, the first sidewall 111 can be an arcuate concave surface recessed in a direction away from the second housing 120. The second reflective protrusion 1111a has a first apex angle 1111a1 on the side away from the first sidewall 111. Here, the first apex angle can be understood as the edge of a triangular prism structure on the side away from the first sidewall 111. The first apex angle 1111a1 faces the normal direction of the first sidewall 111. The normal direction of the arcuate concave surface refers to the direction passing through a specified point on the arcuate concave surface and perpendicular to the tangent plane of the concave surface at that point. For the arcuate concave surface, the normal direction points to the side of the center of curvature of the arcuate concave surface. In this application, since the second reflective protrusion 1111a is disposed on the arc-shaped concave surface, and the normal direction is the normal direction of the corresponding point of the concave surface where the second reflective protrusion 1111a is located, and the first apex 1111a1 faces this direction, it can ensure that the light incident on the second reflective protrusion 1111a is reflected along a preset path, thereby improving the accuracy of directional light guiding.

[0093] In this design, the arc-shaped concave surface of the first sidewall 111 can initially converge the incident light rays, guiding them towards the second reflective protrusion 1111a. The first apex 1111a1 of the second reflective protrusion 1111a faces the normal direction of the arc-shaped concave surface, which can accurately reflect the converged light rays along a preset direction, greatly improving the directional emission efficiency of the light rays, while avoiding light scattering loss in non-target directions.

[0094] In addition, the curved surface structure of the first sidewall 111 is an arc-shaped concave surface, which can disperse external pressure and vibration impact, and improve the deformation resistance of the first sidewall 111 compared to the planar structure of the first sidewall 111.

[0095] In the above scheme, the cross-section of each second reflective protrusion 1111a along the direction perpendicular to the first direction X can be an isosceles right triangle. For example... Figure 13 As shown, the waist length of the second reflective protrusion 1111a can be e, and e can range from 0.5 mm to 0.8 mm. Specifically, e can be 0.069 mm. Of course, the waist length of the second reflective protrusion 1111a can also be other values, and this application does not limit it.

[0096] In one embodiment, the light source assembly 200 may further include a mounting base 240, which may include a strip plate 241, a first side plate 242, and a second side plate 243. The extending direction of the strip plate 241 may be the same as the extending direction of the strip light guide 230. The first side plate 242 and the second side plate 243 may be located at both ends of the strip plate 241. The strip light guide 230 and the strip plate 241 may be stacked along a third direction Z. The first light-emitting element 210 may be disposed on the first side plate 242, and the second light-emitting element 220 may be disposed on the second side plate 243.

[0097] In this design, the strip plate 241 and the strip light guide 230 are stacked along the third direction Z and extend in the same direction, achieving a narrow and compact layout of the light source assembly 200, which is beneficial for further optimizing the layout structure of the electronic device. The design of the strip plate 241 and the two side plates of the mounting base 240 can be formed in one step by stamping or injection molding, reducing the number of parts and thus further reducing the manufacturing cost of the electronic device. The stacked assembly of the strip light guide 230 and the strip plate 241 is adapted to standardized snap-fit ​​or adhesive processes, eliminating the need for complex positioning tooling and reducing assembly difficulty.

[0098] In the above scheme, the strip plate 241 is disposed on the side of the strip light guide 230 away from the second housing 120. At this time, the second housing 120, the strip light guide 230, the strip plate 241, and the first housing 110 are stacked along the third direction Z.

[0099] Furthermore, a first positioning part 2305 can be provided on the side of the strip light guide 230 facing the strip plate 241, and a second positioning part 2411 can be provided on the side of the strip light guide 230 facing the strip light guide 230. The first positioning part 2305 and the second positioning part 2411 are mutually limiting and cooperating. This solution can improve the assembly accuracy between the strip light guide 230 and the mounting base 240, thereby further reducing the assembly error between the first light-emitting element 210 and the second light-emitting element 220 and the strip light guide 230, and thus avoiding the problem of color deviation.
