Description

Light-emitting components, camera modules, electronic devices, and lighting control methods and apparatus

[0001] This application claims priority to Chinese Patent Application No. 202510127736.3, filed on January 27, 2025, entitled "Light-emitting component, camera module, electronic device and lighting control method and apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and more specifically, to a light-emitting component, a camera module, an electronic device, and a lighting control method and apparatus. Background Technology

[0003] With the widespread use of portable electronic devices such as mobile phones, tablets, and wearable devices, many users have developed the habit of using electronic devices at night. However, when using electronic devices in low-light environments, the strong light from the screen can severely stimulate the eyes, easily leading to visual fatigue and thus affecting eye health.

[0004] To reduce eye strain, many electronic devices are equipped with eye protection modes or night modes, such as reducing blue light radiation from the screen or using pulse width modulation (PWM) dimming to protect the eyes.

[0005] While eye protection mode or night mode can help users relax by reducing screen stimulation to the eyes, it still cannot effectively relieve visual fatigue when users watch the screen for a long time in a dark environment. Summary of the Invention

[0006] This application provides a light-emitting component, a camera module, an electronic device, and a lighting control method and apparatus, which can improve the brightness of ambient light and effectively alleviate visual fatigue.

[0007] In a first aspect, a light-emitting component is provided for use in an electronic device having a housing. The light-emitting component includes: a decorative element for connection to the housing, the decorative element forming a receiving space; a light source disposed in the receiving space; a light-emitting element connected to the decorative element for emitting light emitted by the light source; and a light guide disposed between the light source and the light-emitting element for guiding the light emitted by the light source to the light-emitting element. The light guide includes an incident surface, a first reflecting surface, a second reflecting surface, and an exiting surface. The incident surface is used to converge light from the light source to the first reflecting surface, the first reflecting surface is used to reflect received light to the second reflecting surface, and the second reflecting surface is used to converge received light to the exiting surface.

[0008] The light-emitting component provided in this application can provide stable light, thereby improving the brightness of ambient light in low-light environments, reducing the brightness difference between the surrounding environment and the screen, and effectively alleviating visual fatigue. Furthermore, due to the combination of optical properties of each optical surface of the light guide, the emitted light has a large field of view, as well as high brightness and uniformity, and can scatter soft light over a wide range of environments.

[0009] In conjunction with the first aspect, in one possible implementation, the first reflective surface is used to focus the received light onto the second reflective surface.

[0010] The first reflecting surface has a converging effect on the received light, which helps to improve the brightness of the emitted light. By adjusting the optical parameters of the first reflecting surface, it is helpful to increase the field of view of the emitted light, thereby expanding the coverage of the light and improving the uniformity of the light spot.

[0011] In conjunction with the first aspect, in one possible implementation, the first reflecting surface is concave in the direction in which light is incident on the first reflecting surface.

[0012] The light incident on the first reflecting surface will be focused by the first reflecting surface, thereby increasing the brightness of the outgoing light.

[0013] In conjunction with the first aspect, in one possible implementation, the second reflecting surface is concave in the direction in which light is incident on the second reflecting surface.

[0014] The second reflecting surface has a focusing effect on the received light, which helps to improve the brightness and uniformity of the emitted light.

[0015] In conjunction with the first aspect, in one possible implementation, the second reflective surface includes a plurality of first regions, each of which is concave in the direction in which light is incident on the first region.

[0016] Light incident on the second reflecting surface will be converged by multiple first regions, thereby increasing the reflecting area, reducing total internal reflection, and increasing the brightness of the emitted light.

[0017] In conjunction with the first aspect, in one possible implementation, multiple first regions are arranged in an array.

[0018] Multiple first regions are arrayed on the second reflective surface, which can improve the uniformity of light output.

[0019] In conjunction with the first aspect, in one possible implementation, the incident surface includes one or more second regions, each of which is convex in the direction in which light is incident on the second region.

[0020] The incident surface has a focusing effect on the received light, which can concentrate the light emitted by the light source into a smaller area, reduce light scattering and waste, and thus improve the utilization rate of light energy.

[0021] In conjunction with the first aspect, in one possible implementation, the exit surface is a frosted surface or a Fresnel pattern surface.

[0022] A matte surface is rough, which allows for more uniform light distribution. A Fresnel textured surface has concentric circles of varying sizes, which can increase brightness, improve light uniformity, and save space and reduce costs.

[0023] In conjunction with the first aspect, in one possible implementation, the light-emitting element includes an annular light-transmitting region.

[0024] The light source, emitted from the annular light-transmitting area of ​​the light-emitting component, forms a ring-shaped light, providing uniform illumination without increasing shadows and reducing glare, thereby reducing eye fatigue and discomfort. Furthermore, the brightness of the light spot formed by the ring-shaped light gradually increases and then decreases again from the center outwards, improving ambient light brightness over a larger area and enhancing the uniformity of light intensity within the user's field of vision.

[0025] In conjunction with the first aspect, in one possible implementation, the light source and the light-emitting element are respectively disposed on both sides of the light guide element in a first direction, the first direction being the thickness direction of the electronic device.

[0026] The light emitted by the light source passes through the light-emitting component and is directed in front of the light-emitting component, thus achieving front light emission. The emitted light has a higher intensity and the brightness of the light spot formed is higher, which can significantly improve the ambient illuminance.

[0027] In conjunction with the first aspect, in one possible implementation, the light-emitting element includes a light-transmitting region and an opaque region, with the light source located within the projection range of the opaque region in the first direction.

[0028] The light source is blocked by the opaque area of ​​the light-emitting component, thus making the light source invisible and improving its aesthetics.

[0029] In a second aspect, a light-emitting component is provided for use in an electronic device having a housing. The light-emitting component includes: a decorative element for connection to the housing, the decorative element having a receiving space; a light source disposed in the receiving space; a light guide disposed around the light source for receiving and conducting light emitted by the light source; and a light emitter disposed around the light guide and connected to the decorative element for emitting light from the light guide.

[0030] The light-emitting component provided in this application can provide stable light, thereby improving the brightness of ambient light in low-light environments, reducing the brightness difference between the surrounding environment and the screen, and effectively alleviating visual fatigue. The light emitted by the light source passes through the light-emitting element and is directed to the side of the light-emitting component, thus achieving side light emission. The uniformity of the emitted light is better, and the range of the light spot formed is larger, which can significantly improve the ambient illuminance.

[0031] In conjunction with the second aspect, in one possible implementation, the decorative element includes an annular body, in which the light-emitting element is embedded and extends radially through the annular body.

[0032] The light-emitting element can form an annular light-transmitting area for emitting light to the side of the light-emitting component.

[0033] In conjunction with the second aspect, in one possible implementation, the light-emitting element and the decorative element are an integral structure formed by a two-material injection molding process.

[0034] In conjunction with the second aspect, in one possible implementation, the light guide is an optical fiber, wherein the end face of the optical fiber faces the light source, and the cylindrical surface of the optical fiber has an uneven microstructure.

[0035] After the light emitted by the light source enters the optical fiber from the end face, it can be conducted along the optical fiber and diffusely reflected on the cylindrical surface of the optical fiber, so that the light is reflected uniformly in all directions, thereby realizing the emission of light from the entire cylindrical surface of the optical fiber.

[0036] In conjunction with the second aspect, in one possible implementation, the light-emitting component further includes a protective lens located on one side of the light source in a first direction and connected to the decorative element, wherein the protective lens includes an opaque area, and the light source is located within the projection range of the opaque area in the first direction, which is the thickness direction of the electronic device.

[0037] By protecting the light source with a lens, light is prevented from escaping from one side of the lens, and the light source is made invisible from the outside. This improves the appearance.

[0038] In conjunction with the second aspect, in one possible implementation, the electronic device includes a camera portion located within the receiving space formed by the decorative element, wherein the light source is configured to surround the camera; the protective lens also includes a light-transmitting area for light from the subject to pass through to enter the camera.

[0039] The arrangement of the light-emitting components and the camera can save space and reduce the number of openings.

[0040] In conjunction with the first or second aspect, in one possible implementation, the color temperature and / or brightness of the light emitted by the light source are adjustable.

[0041] This allows the lighting to be adjusted to a suitable color temperature and / or brightness based on the actual environment or user needs, thereby maximizing the relief of visual fatigue and improving the user experience.

[0042] In conjunction with the first or second aspect, in one possible implementation, the light source includes a first type of light emitter and a second type of light emitter, wherein the light emitted by the first type of light emitter and the light emitted by the second type of light emitter have different color temperatures, and the first type of light emitter and the second type of light emitter are driven separately.

[0043] The light source includes light emitters with different color temperature parameters, which can make the color temperature of the light emitted by the light source adjustable.

[0044] In conjunction with the first or second aspect, in one possible implementation, the first type of light emitter or the second type of light emitter includes a plurality of light-emitting devices, wherein at least two of the plurality of light-emitting devices are driven in series, or each of the plurality of light-emitting devices is driven individually.

[0045] When light-emitting devices are driven in series, multiple devices can be driven by the same driving circuit, simplifying the driving circuit design. When light-emitting devices are driven individually, the driving current of each device is controlled independently, which can increase the brightness and color temperature adjustment range of the light source.

[0046] In conjunction with the first or second aspect, in one possible implementation, the current used to drive the first type of light emitter is adjustable, and / or the current used to drive the second type of light emitter is adjustable.

[0047] The driving current of light-emitting bodies with different color temperatures is adjustable. By adjusting the current of the light-emitting body, the brightness and color temperature of the light source can be adjusted.

[0049] In one possible implementation, in conjunction with the first or second aspect, the first type of light emitters are centrally symmetrical about the center of the light source or are uniformly distributed around the center of the light source, and the second type of light emitters are centrally symmetrical about the center of the light source or are uniformly distributed around the center of the light source.

[0050] This ensures the uniformity of light output from the light source.

[0051] In conjunction with the first or second aspect, in one possible implementation, the first type of light emitter includes at least one first light-emitting device, the second type of light emitter includes at least one second light-emitting device, and each of the at least one first light-emitting device is disposed adjacent to one or more of the at least one second light-emitting devices.

[0052] The first and second light-emitting devices are arranged adjacent to each other, which can make the color mixing more uniform, thereby improving the uniformity of color temperature and brightness.

[0053] In conjunction with the first or second aspect, in one possible implementation, the first type of light emitter includes two first light emitters, the second type of light emitter includes two second light emitters, the two first light emitters and the two second light emitters are arranged in a rectangular array, wherein the two first light emitters are diagonally arranged, and the two second light emitters are diagonally arranged.

[0054] The four light-emitting devices are arranged in a rectangular array, with the low color temperature light-emitting devices and the high color temperature light-emitting devices close to each other, so that the light can be fully mixed, thus achieving a better uniformity.

[0055] In conjunction with the first or second aspect, in one possible implementation, the light source has at least one of a first lighting mode, a second lighting mode, and a third lighting mode; wherein, in the first lighting mode, one of the first light-emitting devices and / or one of the second light-emitting devices emits light; in the second lighting mode, two of the first light-emitting devices or two of the second light-emitting devices emit light; and in the third lighting mode, both of the first light-emitting devices and both of the second light-emitting devices emit light.

[0056] In the first lighting mode, some light-emitting devices are activated, which can adjust the color temperature and brightness while providing lighting and reducing power consumption.

[0057] In the second lighting mode, the light emitted by the light source is at the baseline color temperature, that is, the same as the color temperature of the first light-emitting device or the same as the color temperature of the second light-emitting device, resulting in good light uniformity.

[0058] In the third lighting mode, all light-emitting devices are working, and the color temperature and brightness can be infinitely adjusted by adjusting the driving current.

[0059] In conjunction with the first or second aspect, in one possible implementation, the light source is used to emit light of one or more colors.

[0060] In conjunction with the first or second aspect, in one possible implementation, the light-emitting component further includes a support member for supporting the light source, the support member being configured to be connected to the housing or the decorative element.

[0061] In conjunction with the first or second aspect, in one possible implementation, the light-emitting component further includes a circuit board electrically connected to the light source.

[0070] In conjunction with the fifth aspect, in one possible implementation, the electronic device further includes a camera trim and one or more cameras, the camera trim being connected to the housing, and the one or more cameras and the light-emitting component being disposed within the coverage area of ​​the camera trim.

[0071] In conjunction with the fifth aspect, in one possible implementation, the electronic device further includes a display screen located on either side of the light-emitting component in the thickness direction.

[0072] In conjunction with the fifth aspect, in one possible implementation, the electronic device also includes a camera located on the same side of the electronic device in the thickness direction as the light-emitting component.

[0073] A sixth aspect provides a lighting control method, applied to an electronic device in the fifth aspect and any implementation thereof, the method comprising: detecting the brightness of ambient light; and prompting a user to turn on an auxiliary light source when a first preset condition is met, wherein the first preset condition includes the brightness of the ambient light being less than or equal to a first threshold.

[0074] In this application, the electronic device can detect the brightness of ambient light to determine whether it is a dark environment.

For example, when the user is using the screen of the electronic device, the brightness of the ambient light is increased to relieve visual fatigue.

[0075] In conjunction with the sixth aspect, in one possible implementation, before prompting the user to turn on the auxiliary light source, the method further includes: detecting the usage status of the electronic device, the usage status of the electronic device being used to determine the usage duration of the electronic device, wherein the first preset condition further includes the usage duration of the electronic device being greater than or equal to a first preset duration.

[0076] When a user is using an electronic device in a low-light environment for a certain period of time, they will be prompted to turn on the auxiliary light source. In this scenario, turning on the auxiliary light source can protect the eyes and avoid false reminders when the user is not using the electronic device.

[0077] In conjunction with the sixth aspect, in one possible implementation, before prompting the user to turn on the auxiliary light source, the method further includes: detecting sound signals in the environment, wherein the first preset condition further includes determining, based on the sound signals in the environment, that music is being played in the environment and the duration of the music is greater than or equal to a second preset duration.

[0083] When the user turns on the auxiliary light source, the electronic device can determine the actual light-emitting device to work based on the posture of the electronic device. This allows the working state of the light-emitting device to be adjusted according to the user's posture when using the electronic device, which can save power while meeting the lighting requirements.

[0084] In conjunction with the sixth aspect, in one possible implementation, the method further includes: displaying a second interface in response to a user's operation, the second interface being used to set the illumination parameters of the auxiliary light source, wherein the illumination parameters of the auxiliary light source include at least one of brightness, color temperature, field of view, and lighting mode.

[0133] The middle frame 11 is a support frame located inside the electronic device 100, used to directly or indirectly support various components, such as batteries, cameras, earpieces, microphones, flashlights, and ribbon cables. The middle frame 11 is generally made of metal (e.g., copper, magnesium alloy, stainless steel) or plastic, and serves to increase the strength of the device body, protect internal components, and withstand pressure. When made of metal, the middle frame 11 can also serve as the grounding terminal of the electronic device 100. In this embodiment, the middle frame 11 can be used to fix and support the display screen 102 and the circuit board 103.

[0134] The bezel 12 is a structure that surrounds the outer periphery of the electronic device 100. Referring to Figure 2, the bezel 12 can extend around the periphery of the electronic device 100, for example, it can surround the four sides of the display screen 102 to help fix and protect the display screen 102, thereby reducing the adverse effects of collisions, drops, etc. on the display screen 102. The bezel 12 can be a metal bezel or a non-metallic bezel (or an insulating bezel), wherein the metal bezel is made of metal materials such as copper, magnesium alloy, stainless steel, etc., and the non-metallic bezel can be made of materials such as plastic, glass, or ceramic.

[0135] The back cover 13 is a structure on the electronic device 100 that is disposed opposite to the display screen 102 and connected to the frame 12. It is used to enclose the components of the electronic device 100 inside the electronic device and also to prevent dust, impact, and hardware scratches. In some embodiments, the back cover 13 can also be used to fix other displays besides the display screen 102, or to fix antennas, etc. The back cover 13 can be a back cover made of metal (i.e., a metal back cover) or a back cover made of non-conductive material (i.e., a non-metal back cover), such as a glass back cover or a plastic back cover.

[0136] The middle frame 11 and the side frame 12 can be either separate or integrated; this embodiment does not limit this. When the middle frame 11 and the side frame 12 are separate, they are two different components of the housing 101, and can be assembled together by means of snap-fit, riveting, gluing, or fastening, and can be separated when disassembly is required. When the middle frame 11 and the side frame 12 are integrated, the connection between them cannot be separated. For example, the middle frame 11 and the side frame 12 can be manufactured using a one-piece molding method, or assembled using a permanent connection method such as welding. In the case of an integrated middle frame and side frame, the outer perimeter of the middle frame can be considered as the side frame of the electronic device 100, meaning the side frame 12 can be considered as part of the middle frame 11.

[0137] The frame 12 and the back cover 13 can be either separate or integrated; this embodiment does not limit this. When the frame 12 and the back cover 13 are separate, they are two different components of the housing 101, and can be assembled together by means of snap-fit, riveting, bonding, fastening, etc., and can be separated when disassembly is required. When the frame 12 and the back cover 13 are integrated, the connection between them cannot be separated. For example, the frame 12 and the back cover 13 can be manufactured using a one-piece molding method, or assembled using a permanent connection method such as welding. In the case of an integrated frame and back cover, the outer periphery of the back cover 13 can be considered as the frame of the electronic device 100, that is, the frame 12 can be considered as part of the back cover 13.

[0138] In other words, the frame 12 can be a separate part relative to the middle frame 11 and the back cover 13, or a part of the middle frame 11, or a part of the back cover 13.

[0139] Display screen 102 is used to display images. For example, display screen 102 can display the lighting control interface involved in this application. Display screen 102 can be a liquid crystal display (LCD) screen, an organic light emitting diode (OLED) screen, etc. If display screen 102 is an LCD screen, electronic device 100 also includes a backlight unit (BLU) for providing a light source to the LCD screen. If display screen 102 is an OLED screen, the OLED screen is self-emissive, therefore the electronic device 100 does not need to include the aforementioned backlight unit. Display screen 102 can be a regular screen, or an irregularly shaped screen, or a foldable screen, etc.

[0140] In this embodiment, the display screen 102 has a light-emitting surface capable of displaying images, and the side surface of the display screen 102 opposite to the light-emitting surface can be referred to as the back surface of the display screen 102. The back surface of the display screen 102 is housed in the receiving space formed by the housing 101 and is not visible to the user. The back cover 13 of the above design can be located on the back surface of the display screen 102.

[0141] In some embodiments, the electronic device 100 may further include a cover plate, such as a glass cover plate, for protecting the display screen 102. The cover plate has a certain degree of flexibility and can be set tightly against the display screen 102, for example, by means of adhesive.

[0142] Circuit board 103 serves as a support for electronic components and also as a carrier for electrical connections between them. Circuit board 103 can be a rigid circuit board, such as a printed circuit board (PCB), a flexible printed circuit board (FPC), or a combination of rigid and flexible circuit boards. For example, circuit board 103 can be a single-sided board, a double-sided board, or a multilayer circuit board. Circuit board 103 can also be a ceramic circuit board, an alumina ceramic circuit board, an aluminum nitride ceramic circuit board, an aluminum substrate, a high-frequency board, a thick copper plate, or an impedance board.

[0143] The circuit board 103 has conductive patterns, and electronic components can be electrically connected by wiring between different conductive patterns. The circuit board after wiring can include functional networks and non-functional networks. Functional networks can provide a specific electrical function, such as charging, radio frequency, antenna, multimedia, data storage, sensors, cameras, lighting control, etc. Non-functional networks do not provide electrical functions and are mainly used to achieve mechanical connections between the soldered structural components and the circuit board 103. Non-functional networks are usually grounded (GND) or floating (not connected to any functional network or GND network) to isolate the structural components carried on the circuit board 103 from the functional networks and prevent electric shock or equipment damage caused by accidental contact.

[0144] In some embodiments, the electronic device 100 may further include a circuit board bracket for securing the circuit board 103 to the mid-frame 11. The circuit board bracket may be made of metal and serve as a conductive ground (GND). The circuit board bracket may also be an insulating bracket on which metal components may be mounted.

[0145] In this embodiment, the electronic components carried on the circuit board 103 include, but are not limited to, capacitors, inductors, resistors, processors, memory, cameras, flashlights, microphones, and batteries. The electronic components carried on the circuit board 103 can form multiple functional modules, such as wireless fidelity (WiFi) modules, radio frequency power amplifiers (RFPA), radio frequency integrated circuits (RFIC), system-in-package (SiP), system-on-chip (SOC), audio modules, and power management units (PMUs), to achieve corresponding functions. The shape of the circuit board 103 can be designed according to the shape of the electronic device 100 and the position and shape of the functional modules to be arranged inside the electronic device 100.

[0146] For example, referring to Figures 1 and 2, an electronic device 100 may include one or more cameras 106 for capturing images, and the cameras 106 may be fixed to a circuit board 103. With the development of thinner and smaller electronic devices, the overall thickness of electronic devices is usually made relatively thin. Therefore, the camera 106 generally protrudes from the surface of the housing of the electronic device 100, that is, the thickness of the area where the camera 106 is located is greater than the thickness of other areas.

[0147] As shown in Figures 1 and 2, to avoid affecting the appearance and protect the camera 106, a camera decorative piece 105 is typically provided around the camera 106. The camera decorative piece 105 is connected to the housing 101 (e.g., the back cover 13), covering and decorating the camera 106. The camera decorative piece 105 forms a certain accommodating space to accommodate a portion of the camera 106 in the height direction. Correspondingly, the camera decorative piece 105 is provided with a light-transmitting hole to allow light from the subject to pass through and be received by the camera 106. For ease of description, in this embodiment, the area where the camera decorative piece 105 is located is referred to as the camera decoration area A, the area enclosed by the dashed line in Figure 1, which can also be called the DECO area.

[0148] In some embodiments, the electronic device 100 may further include a protective lens for protecting the camera 106. The protective lens is disposed on the camera trim 105 and covers the camera 106. The material of the protective lens may be glass, sapphire, ceramic, etc., and this application does not impose any special limitations on it. For example, the protective lens is transparent or partially transparent, allowing light from outside the electronic device 100 to enter the camera 106 through the protective lens.

[0149] In some embodiments, to assist in taking photos, as shown in Figures 1 and 2, the electronic device 100 also includes a flash light 107. The flash light 107 is used to supplement light when the subject is poorly lit. The flash light 107 mainly stores high-voltage electricity in a capacitor, and the pulse trigger causes the flash tube to discharge, completing a momentary flash. Therefore, the flash time of the flash light 107 is extremely short, typically between 1 / 1000 of a second and 1 / 20000 of a second or even shorter.

[0150] In some embodiments, as shown in FIG1, the flash 107 may be located in the camera decoration area A, or the flash 107 may be located in a different area from the camera decoration area A.

[0151] In some embodiments, referring to FIG2, the electronic device 100 may further include a power supply 104 for supplying power to electrical components such as a circuit board 103, a display screen 102, a camera 106, and a flash 107. For example, the power supply 104 may be a lithium-ion battery, a lithium polymer battery, a nickel-metal hydride battery, a nickel-cadmium battery, a solid-state battery, a metal-air battery, etc.

[0152] In this embodiment of the application, to achieve an eye-protection effect, the electronic device 100 also includes a fill light 108. The fill light 108 can be turned on in low-light environments to improve the brightness of ambient light, reduce the brightness difference between the surrounding environment and the screen, thereby reducing screen stimulation to the eyes, effectively relieving visual fatigue, and maintaining eye health. The specific structure of the fill light 108 will be described in more detail below with reference to the accompanying drawings, and will not be elaborated here.

[0153] In some embodiments, referring to FIG1, the fill light 108 may be disposed in the camera decoration area A, that is, the fill light 108 and the camera 106 are disposed in the same area, which protrudes from the housing surface of the electronic device 100, and different positions in this area have approximately the same height. For example, both the fill light 108 and the camera 106 are disposed within the coverage area of ​​the camera decoration 105.

[0154] In other embodiments, referring to FIG3, the supplementary light 108 may be disposed in a region different from the camera decorative area A, such as region A0, wherein region A0 may protrude from the housing surface of the electronic device 100 or may be flush with the housing surface of the electronic device 100. When region A0 protrudes from the housing surface of the electronic device, the height of the protrusion of region A0 may be the same as or different from the height of the protrusion of camera decorative area A, and this application does not limit this.

[0155] It should be understood that the structures illustrated in Figures 1 to 3 do not constitute a specific limitation on the electronic device 100. The electronic device 100 may include more or fewer components than illustrated, and the electronic device 100 may also have a different component arrangement than illustrated. In addition, different types of electronic devices 100 include different components, and the electronic device structures provided in the embodiments of this application are merely illustrative examples.

[0156] Figure 4 shows a schematic structural diagram of a light-emitting component provided in an embodiment of this application. Figure 5 shows a schematic cross-sectional view of the light-emitting component 200 in Figure 4 taken along line BB. The light-emitting component 200 shown in Figures 4 and 5 can be applied to the electronic device 100 shown in Figures 1, 2 or 3. For example, the light-emitting component 200 can be a specific example of the aforementioned supplementary light 108.

[0157] As shown in Figures 4 and 5, the light-emitting component 200 includes a decorative element 210, a light source 220, a light guide 230, and a light emitter 240. The decorative element 210 forms a receiving space in which the light source 220, light guide 230, and light emitter 240 are disposed. The light source 220 and light emitter 240 are respectively disposed on both sides of the light guide 230 in a first direction (e.g., the Z direction shown in the figure), which is the thickness direction of the electronic device. The decorative element 210 is used to connect to the housing of the electronic device, thus serving to support and fix other components in the light-emitting component 200. A portion of the decorative element 210 is also exposed to the environment, thus also having a decorative effect. The light source 220 is used to emit light; for example, in a low-light environment, the light source 220 can provide auxiliary light to the environment to increase the illumination effect and improve ambient light brightness. The light guide 230 is disposed between the light source 220 and the light emitter 240 to conduct the light emitted by the light source 220 to the light emitter 240. The light-emitting element 240 is connected to the decorative element 210 and is used to receive light from the light guide element 230 so as to emit light emitted by the light source 220 into the environment.

[0158] It should be noted that, for ease of demonstration and understanding, the decorative part 210 in Figure 4 is made transparent, but this does not mean that the decorative part 210 is translucent. In practical applications, to prevent light leakage from the light source 220 from affecting other components, the decorative part 210 can be made of opaque materials, such as metal materials (e.g., stainless steel, aluminum alloy, etc.) or ceramic materials.

[0159] A separate fill light on an electronic device, such as the light-emitting component 200 shown in Figure 4, can provide stable light, thereby improving the brightness of ambient light in low-light environments, reducing the brightness difference between the surrounding environment and the screen, and effectively alleviating eye strain. Furthermore, the separate design of the fill light allows users to control its on / off state as needed, providing a better user experience. For example, in situations with insufficient natural light or dim indoor lighting, the fill light can be turned on for supplementary lighting, photography, illumination, and enhancing ambiance.

[0160] In addition, based on the light-emitting component 200 shown in Figure 4, the light emitted by the light source 220 passes through the light-emitting element 240 and is directed to the front of the light-emitting component 200, thereby achieving front light emission. The intensity of the emitted light is higher, the brightness of the light spot formed is higher, and the ambient illuminance can be significantly improved.

[0161] In some embodiments, referring to FIG4 or FIG5, the light-emitting element 240 includes a light-transmitting region 241 and an opaque region 242, and the light source 220 is located within the projection range of the opaque region 242 in a first direction. That is, when viewed from the side where the light-emitting element 240 is located towards the side where the light source 220 is located, the light source 220 is blocked by the opaque region 242 of the light-emitting element 240, thus achieving visual invisibility of the light source 220, i.e., seeing the light but not the lamp, which can improve aesthetics. Therefore, it can be understood that part of the function of the light-emitting element 240 in this application is to emit light, but it is not limited to emitting light. For example, the light-emitting element 240 can also have the function of blocking light-emitting devices.

[0162] In some embodiments, referring to FIG4, the light-emitting element 240 includes an annular (e.g., circular) light-transmitting area, that is, the aforementioned light-transmitting area 241 is annular.

[0163] The light source 220, after emitting light from the annular light-transmitting area 241 of the light-emitting element 240, can form annular light, which can provide uniform illumination without increasing shadows and reduce glare, thereby reducing eye fatigue and discomfort. In addition, the brightness of the light spot formed by the annular light shows a trend of increasing and then decreasing from the center outwards. That is, the position of the brightest spot is not at the center but in the annular area at a certain distance from the center. In this way, the light emitted by the light source 220 can improve the ambient light brightness over a large area and improve the uniformity of light intensity within the user's field of view.

[0164] In some embodiments, a light-emitting element 240 can be formed by partially coating an ink layer (such as a black ink layer) onto a light-transmitting element (such as a glass lens), wherein the area on the light-transmitting element covered with the ink layer is an opaque area 242, and the area on the light-transmitting element not covered with the ink layer is a light-transmitting area 241.

[0165] The ink layer can absorb light of a specific wavelength. For example, black ink can absorb visible light. Therefore, the area covered by the ink layer can block the passage of light of the corresponding wavelength, thus achieving an opaque effect.

[0166] In other embodiments, a two-color injection molding process can be used to injection mold the light-transmitting material and the opaque material into one piece to form the light-emitting part 240, wherein the area where the opaque material is located is the opaque area 242, and the area where the light-transmitting material is located is the light-transmitting area 241.

[0167] Two-color injection molding, also known as two-material injection molding, is a molding process that involves injecting two different materials into the same mold, resulting in a part formed from both materials. Two-color injection molding can integrate multiple functions into a single component, saving design space and assembly steps.

[0168] In some embodiments, the light-emitting element 240 can be connected to the decorative element 210 by means of bonding, welding, riveting, snap-fitting, etc. By way of example and not limitation, referring to FIG5 or FIG7, the light-emitting element 240 can be bonded to the decorative element 210 by adhesive 270.

[0169] In some embodiments, the light-emitting element 240 may be circular, elliptical, square, or other shapes. In practical applications, the shape of the light-emitting element 240 can be designed according to space and appearance requirements; this is merely an illustrative example.

[0170] In some embodiments, the light-emitting element 240 may include at least one of the following materials: polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polyethylene terephthalate-1,4-cyclohexanedimeth yleneterephthalate (PETG), or copolymers of cycloolefin (COC).

[0171] In some embodiments, light incident from the light source 220 onto the light guide 230 is reflected at least twice within the light guide 230 before entering the light emitter 240. For example, referring to FIG. 5, the light guide 230 may include an incident surface 231, an exit surface 232, and at least two reflecting surfaces 233. The incident surface 231 is disposed opposite to the light source 220 and is used to receive light from the light source 220. The exit surface 232 is disposed opposite to the light-transmitting region 241 of the light emitter 240 and is used to emit light into the light emitter 240. The at least two reflecting surfaces 233 are used to conduct light from the incident surface 231 to the exit surface 232 after multiple reflections.

[0172] After the light emitted by the light source 220 is reflected at least twice in the light guide 230, the light can be emitted from the light guide 230 away from the side where the light source 220 is located, thereby achieving front light emission.

[0173] By way of example and not limitation, the light guide 230 may include two reflective surfaces 233. As shown in FIG5, the light guide 230 may include an incident surface 231, an exit surface 232, a first reflective surface 2331 and a second reflective surface 2332. Here, the first reflective surface 2331 and the second reflective surface 2332 are examples of the reflective surface 233. The first reflective surface 2331 is used to receive light from the incident surface 231 and reflect it to the second reflective surface 2332, and the second reflective surface 2332 is used to receive light from the first reflective surface 2331 and reflect it to the exit surface 232.

[0174] For ease of understanding, in Figure 5 and other similar cross-sectional views (as shown in Figures 7 and 8), a hollow triangle “△” is used as the reference point for the incident surface 231. Specifically, the area between two adjacent “△” symbols corresponds to the incident surface 231. A solid circle “●” is used as the reference point for the first reflecting surface 2331. Specifically, the area between two adjacent “●” symbols corresponds to the first reflecting surface 2331. A hollow square “□” is used as the reference point for the second reflecting surface 2332. Specifically, the area between two adjacent “□” symbols corresponds to the second reflecting surface 2332. A solid square “■” is used as the reference point for the exit surface 232. Specifically, the area between two adjacent “■” symbols corresponds to the exit surface 232. It should be noted that the two adjacent “△” / “●” / “□” / “■” symbols mentioned above refer to two symbols without any other type of symbol between them. Furthermore, it is understood that the positions of the above symbols in the figure are merely exemplary, and the areas and positions of the surfaces identified by the above symbols are also merely exemplary and do not constitute any limitation on this application.

[0175] In some embodiments, the incident surface 231 is used to converge light from the light source 220 to the first reflecting surface 2331, the first reflecting surface 2331 is used to reflect the received light to the second reflecting surface 2332, and the second reflecting surface 2332 is used to converge the received light to the exiting surface 232. In other words, after the light from the light source 220 enters the light guide 230 from the incident surface 231, it is first converged to the first reflecting surface 2331 by the focusing effect of the incident surface 231, then reflected to the second reflecting surface 2332 by the first reflecting surface 2331, and then converged to the exiting surface 232 by the focusing effect of the second reflecting surface 2332, and finally enters the light emitting element 240 through the exiting surface 232.

[0176] The incident surface 231 has a focusing effect on the received light, which can concentrate the light emitted by the light source 220 in a smaller area, reduce light scattering and waste, and thus improve the utilization rate of light energy.

[0177] The first reflecting surface 2331 reflects the received light. By adjusting parameters such as the shape, focal length, distance between the first reflecting surface 2331 and the incident surface 231, and distance between the first reflecting surface 2331 and the second reflecting surface 2332, the degree of light scattering and the field of view of the light reflected from the first reflecting surface 2331 can be adjusted. Furthermore, by adjusting the above parameters, the field of view (FOV) of the emitted light can be increased, that is, the angular range of the light emitted from the light emitting element 240 can be increased, thereby expanding the coverage area of ​​the light (i.e., the illumination range) and improving the uniformity of the light spot.

[0178] The second reflective surface 2332 has a focusing effect on the received light, which helps to improve the brightness and uniformity of the emitted light. By adjusting parameters such as the shape, focal length, distance between the second reflective surface 2332 and the first reflective surface 2331, and distance between the second reflective surface 2332 and the emitting surface 232, the field of view (FOV) of the light reflected from the second reflective surface 2332 can be adjusted, which can further increase the FOV of the light emitted from the light emitting element 240 and expand the illumination range of the light.

[0179] In some embodiments, at least a portion of the incident surface 231 is convex in the direction in which light is incident on the incident surface 231. That is, viewed from the direction in which light is incident on the incident surface 231, at least a portion of the incident surface 231 is convex, meaning that at least a portion of the incident surface 231 protrudes away from the direction in which light is incident on the incident surface 231; for example, this at least portion may be formed as a curved surface. For example, referring to FIG. 6, the incident surface 231 may include one or more second regions 2311, each of which is convex when viewed from the direction in which light is incident on the incident surface 231, or in other words, each second region 2311 protrudes towards the light source 220. For example, referring to FIG. 6(a), the incident surface 231 may include a second region 2311 for converging light emitted from the light source 220. For example, referring to Figure 6(b), the incident surface 231 may include a plurality of second regions 2311, each of which is used to converge a portion of the light emitted by the light source 220.

[0180] In some embodiments, the light source 220 may include a plurality of light-emitting devices, and each second region 2311 may correspond to at least one of the plurality of light-emitting devices. For example, when the incident surface 231 includes one second region 2311, that one second region 2311 corresponds to the plurality of light-emitting devices. As another example, when the incident surface 231 includes a plurality of second regions 2311, each of the plurality of second regions 2311 corresponds to at least one of the plurality of light-emitting devices.

[0181] For example, the light source 220 includes a plurality of light-emitting devices, and the incident surface 231 includes a plurality of second regions 2311, which correspond one-to-one with the plurality of light-emitting devices, that is, one second region 2311 corresponds to one light-emitting device.

[0182] In practical applications, the number of second regions 2311 can be determined according to the number of light-emitting devices, the area of ​​the incident surface 231, etc. The above is only an example.

[0183] In some embodiments, the second region 2311 may be a curved surface. The curvature of the surface may be variable or constant. For example, the second region 2311 may be a portion of a sphere with the same curvature at all points on the surface. Since all points on the sphere have equal refraction of light, a more stable light-focusing effect can be achieved.

[0184] In practical applications, the shape of the second region 2311 can be determined according to the optical path design requirements, etc. The above is only an example.

[0185] In some embodiments, the first reflective surface 2331 is used to focus the received light onto the second reflective surface 2332. The first reflective surface 2331 has a light-focusing effect, which helps to improve the brightness of the light, and can also adjust the FOV of the light reflected by the first reflective surface 2331, thereby further adjusting the FOV of the light emitted from the light-emitting element 240.

[0186] In some embodiments, the first reflective surface 2331 is concave in the direction in which light is incident on the first reflective surface 2331. That is, viewed from the direction in which light is incident on the first reflective surface 2331, the first reflective surface 2331 appears concave. If the light guide 230 is an integral mirror, then from the appearance of the light guide 230, the first reflective surface 2331 protrudes outward from the outside of the light guide 230. For example, when the first reflective surface 2331 is concave, its curvature can be varied or constant. For ease of understanding, Figure 9 shows a three-dimensional schematic diagram of the light guide 230, which shows a schematic diagram of the first reflective surface 2331.

[0187] In some embodiments, the first reflecting surface 2331 is a rotating surface, wherein the generatrix of the first reflecting surface 2331 includes curves and / or straight lines.

[0188] For example, referring to Figure 5 or Figure 7, the generatrix of the first reflective surface 2331 can be a curve, wherein when viewed in the direction in which light is incident on the generatrix, the curve bends away from the light guide 230, which can be understood as the curve protruding outward of the light guide 230. By way of example and not limitation, the curve can be part of an arc or a parabola. When the generatrix of the first reflective surface 2331 is a curve, the first reflective surface 2331 appears as a concave surface when viewed in the direction in which light is incident on the first reflective surface 2331, and can have light-gathering capability.

[0189] For example, the generatrix of the first reflective surface 2331 can be a straight line, which is inclined relative to the center line of the light source 220 (or the center line of the light guide 230). Specifically, the distance between this straight line and the center line of the light source 220 increases from small to large in the direction from the light source 220 to the light emitting element 240. By way of example and not limitation, this straight line can intersect the center line of the light source 220, or the minimum distance between this straight line and the center line of the light source 220 can be greater than 0. Accordingly, the first reflective surface 2331 can be a conical surface or the side surface of a frustum (the side surface of a frustum can be considered as the part remaining after the tip of the conical surface has been cut off).

[0190] For example, the generatrix of the first reflective surface 2331 may include a connected curved portion and a straight portion, wherein the straight portion is closer to the center line of the light source 220 (or the center line of the light guide 230) than the curved portion. For example, the curved portion bends and protrudes in the direction of light incidence (i.e. away from the light guide 230) when viewed from the direction in which light is incident on the curved portion, and the straight portion intersects the center line of the light source 220, wherein the angle between the straight portion and the center line of the light source 220 is less than or equal to 90°, that is, the straight portion may be perpendicular or inclined relative to the center line of the light source 220.

[0191] For example, the generatrix of the first reflective surface 2331 may include a connected first straight section and a second straight section, wherein the second straight section is closer to the center line of the light source 220 (or the center line of the light guide 230) than the first straight section. For example, the first straight section may be inclined relative to the center line of the light source 220, and the distance between the position on the first straight section for connecting with the second straight section and the center line of the light source 220 is closer than other points on the first straight section, while the second straight section intersects the center line of the light source 220.

[0192] In some embodiments, the conductor of the first reflecting surface 2331 can be circular. Thus, the first reflecting surface 2331 is a rotating surface (or a surface of revolution), which has the same reflection effect on light in the circumferential direction, which helps to ensure the uniformity of the emitted light (i.e., the light emitted from the light emitting element 240).

[0193] It should be noted that the curved surface involved in this application is a geometric figure, which is a set of trajectories formed by the continuous movement of a moving line (such as a straight line or a curve) in space. The line that produces the curved surface is called the generatrix, and the line that controls the movement of the generatrix is ​​called the conductor.

[0194] In some embodiments, referring to FIG5 or FIG7, the first reflective surface 2331 is located within the projection range of the opaque region 242 of the light-emitting element 240 in the first direction. This makes the first reflective surface 2331 invisible, thereby improving the aesthetics of the light-emitting component 200.

[0195] In some embodiments, the first reflective surface 2331 may include a plurality of sub-regions, each of which is concave when viewed from the direction in which light is incident on the corresponding sub-region. Exemplarily, the plurality of sub-regions may be arranged in an array, such as an array arranged along the generatrix extension direction of the first reflective surface 2331 or a circumferential array arranged along the rotation axis of the first reflective surface 2331. Light incident on the first reflective surface 2331 is reflected by the plurality of sub-regions, which can increase the reflective area, reduce total internal reflection, and improve the brightness of the reflected light.

[0196] In this application, the degree and range of light scattering can be controlled by adjusting the distance between the incident surface 231 and the first reflecting surface 2331, as well as their respective focal lengths. Therefore, in practical applications, the optical parameters of the incident surface 231 and the first reflecting surface 2331 can be designed according to space requirements and optical path design requirements.

[0197] In some embodiments, referring back to Figures 5 or 7, the second reflective surface 2332 is concave in the direction in which light is incident on the second reflective surface 2332. That is, viewed from the direction in which light is incident on the second reflective surface 2332, the second reflective surface 2332 appears concave. If the light guide 230 is an integral mirror, then from the appearance of the light guide 230, the second reflective surface 2332 protrudes outward from the light guide 230. Exemplarily, when the second reflective surface 2332 is concave, its curvature can be varied or constant. For ease of understanding, Figure 8 shows a three-dimensional schematic diagram of the light guide 230, which illustrates a schematic diagram of the second reflective surface 2332.

[0198] In some embodiments, the second reflective surface 2332 is a rotating surface, wherein the generatrix of the second reflective surface 2332 includes curves and / or straight lines.

[0199] For example, referring to Figure 5 or Figure 7, the generatrix of the second reflective surface 2332 can be a curve, wherein when viewed in the direction in which light is incident on the generatrix, the curve bends away from the light guide 230, which can be understood as the curve protruding outward of the light guide 230. By way of example and not limitation, the curve can be part of an arc or a parabola. When the generatrix of the second reflective surface 2332 is a curve, the second reflective surface 2332 appears as a concave surface when viewed in the direction in which light is incident on the second reflective surface 2332, and can have light-gathering capability.

[0200] For example, when the generatrix of the second reflecting surface 2332 is part of a parabola, the second reflecting surface 2332 can be part of a parabolic surface (i.e., a surface obtained by rotating a parabola one revolution). For example, the second reflecting surface 2332 can be part of an elliptic parabola or a hyperbolic parabola.

[0201] The second reflective surface 2332 is a protruding surface on the outer side of the light guide 230, which can ensure that the light from the first reflective surface 2331 is reflected to the output surface 232 according to the optical path design requirements, thereby giving the output light a larger field of view.

[0202] For example, the generatrix of the second reflective surface 2332 can be a straight line, which is inclined relative to the center line of the light source 220 (or the center line of the light guide 230). Specifically, the distance between this straight line and the center line of the light source 220 increases from small to large in the direction from the light source 220 to the light emitting element 240. By way of example and not limitation, the minimum distance between this straight line and the center line of the light source 220 is greater than 0.

[0203] For example, the generatrix of the second reflective surface 2332 may include a connected curved portion and a straight portion, wherein the curved portion bends and protrudes in the direction of light incidence (i.e. away from the light guide 230) when viewed from the direction in which light is incident on the curved portion, and the straight portion is inclined relative to the center line of the light source 220.

[0204] For example, the generatrix of the second reflective surface 2332 may include a connected third straight section and a fourth straight section, wherein the third straight section is inclined relative to the center line of the light source 220, and the fourth straight section is inclined relative to the center line of the light source 220, and the degree of inclination of the third straight section and the fourth straight section is different.

[0205] In some embodiments, the conductor of the second reflective surface 2332 can be circular. Thus, the second reflective surface 2332 is a rotating surface (or a surface of revolution), which has the same reflection effect on light in the circumferential direction, which helps to ensure the uniformity of the emitted light (i.e., the light emitted from the light emitting element 240).

[0206] In some embodiments, at least a portion of the second reflective surface 2332 is located within the projection range of the light-transmitting region 241 of the light-emitting member 240 in the first direction. In this way, the second reflective surface 2332 can uniformly reflect light to the emitting surface 232, improving the uniformity of light emission and forming annular light emission.

[0207] In some embodiments, referring to the partially enlarged schematic diagram C in FIG8, the second reflective surface 2332 may include a plurality of first regions 233a, each of which is concave when viewed from the direction in which light is incident on the corresponding region. That is, in appearance, the first regions 233a protrude outward from the light guide 230. For example, each first region 233a is a parabola or a part of a parabola. Exemplarily, the plurality of first regions 233a may be arranged in an array, for example, in an array arranged along the generatrix extension direction of the second reflective surface 2332 or in a circumferential array arranged along the rotation axis of the second reflective surface 2332. For ease of understanding, FIG9 or FIG10 shows a perspective schematic diagram of the light guide 230, showing a schematic arrangement of the first regions 233a.

[0208] The second reflective surface 2332 includes an array of first regions 233a, which protrude away from the light guide 230. Referring to the enlarged schematic diagram C in Figure 8 showing the reflection effect of the first region 233a on parallel light rays, light incident on the second reflective surface 2332 will be reflected by multiple first regions 233a, reducing total internal reflection. Furthermore, the first regions 233a have a converging effect on light, thereby increasing the brightness of the emitted light. When the first region 233a is at least a part of a parabolic surface, it can converge parallel light rays incident on it, improving the emitted light brightness.

[0209] In this application, the brightness, uniformity, and field of view (FOV) angle of light can be controlled by adjusting the curvature of the second reflective surface 2332 and the first region 233a. Therefore, in practical applications, the optical parameters of the second reflective surface 2332 can be designed according to the requirements for brightness and uniformity.

[0210] In some embodiments, the emitting surface 232 is a frosted surface or a Fresnel patterned surface, or an optical element with a frosted surface or a Fresnel patterned surface, such as a lens, may be disposed between the emitting surface 232 and the light-emitting element 240.

[0211] A matte surface is rough, which allows for more uniform light distribution. A Fresnel textured surface has concentric circles of varying sizes, which can increase brightness, improve light uniformity, and save space and reduce costs.

[0212] In some embodiments, the emission surface 232 is a toroidal surface, such as a circular torus. For ease of understanding, FIG9 shows a three-dimensional schematic diagram of the light guide 230, which illustrates a schematic diagram of the emission surface 232.

[0213] In some embodiments, the exit surface 232 is a plane.

[0214] In some embodiments, the incident surface 231 and the second reflecting surface 2332 are located on the same side of the first reflecting surface 2331 (or the exiting surface 232). The exiting surface 232 and the first reflecting surface 2331 are located on the same side of the second reflecting surface 2332 (or the incident surface 231).

[0215] In some embodiments, the second reflecting surface 2332 is disposed around the incident surface 231. Other surfaces, such as non-optical surfaces (i.e., surfaces that do not function in the light path transmission), may be disposed between the second reflecting surface 2332 and the incident surface 231. Accordingly, referring to FIG5 or FIG7, there is a certain interval between the “△” symbol for identifying the incident surface 231 and the adjacent “□” symbol for identifying the second reflecting surface 2332. Alternatively, the second reflecting surface 2332 and the incident surface 231 may be directly connected, that is, the boundary of the second reflecting surface 2332 near the incident surface 231 coincides with the boundary of the incident surface 231 near the second reflecting surface 2332. For example, based on FIG5, the “△” symbol for identifying the incident surface 231 and the adjacent “□” symbol for identifying the second reflecting surface 2332 may be located in the same position.

[0216] In some embodiments, the emitting surface 232 is disposed around the first reflecting surface 2331. Other surfaces, such as non-optical surfaces, may be disposed between the emitting surface 232 and the first reflecting surface 2331. Accordingly, referring to FIG5 or FIG7, there is a certain interval between the "●" symbol used to identify the first reflecting surface 2331 and the adjacent "■" symbol used to identify the emitting surface 232. Alternatively, the emitting surface 232 and the first reflecting surface 2331 can be directly connected, that is, the boundary of the first reflecting surface 2331 near the emitting surface 232 coincides with the boundary of the emitting surface 232 near the first reflecting surface 2331. For example, based on FIG5 or FIG7, the "●" symbol used to identify the first reflecting surface 2331 and the adjacent "■" symbol used to identify the emitting surface 232 can be marked in the same position.

[0217] In some embodiments, referring to FIG5 or FIG7, the projection of the first reflective surface 2331 on the direction from the light source 220 to the light emitter 240 (or the direction from the light emitter 240 to the light source 220) (such as the thickness direction of the electronic device) is a circular projection. It can be understood that all the profile lines of the first reflective surface 2331 (referring to the lines when the generatrix is ​​at any position on the curved surface) converge at a point, or that one end of the generatrix of the first reflective surface 2331 is located on the rotation center line.

[0218] Accordingly, referring to Figure 5 or Figure 7, if the incident surface 231 includes a second region 2311, the projection of the incident surface 231 onto the direction from the light source 220 to the light emitting element 240 (or the direction from the light emitting element 240 to the light source 220) (such as the thickness direction of the electronic device) can be a circular projection. This can be understood as all the generatrices of the incident surface 231 converging at a point, or in other words, one end of the generatrix of the incident surface 231 being located on the rotation center line. If the incident surface 231 includes multiple second regions 2311, then the area between two opposing second regions 2311 can be a continuous plane.

[0219] In some embodiments, referring to FIG11, the projection of the first reflective surface 2331 onto the direction from the light source 220 to the light emitting element 240 (or the direction from the light emitting element 240 to the light source 220) (such as the thickness direction of the electronic device) is an annular projection. This can be understood as all the generatrices of the first reflective surface 2331 not converging at one point, or in other words, one end of the generatrices of the first reflective surface 2331 being a certain distance from the rotation center line. As shown in FIG11(b), from an external perspective, the first reflective surface 2331 can form a through hole 233b.

[0220] Accordingly, referring to Figure 11, if the incident surface 231 includes a second region 2311, the projection of the incident surface 231 onto the direction from the light source 220 to the light emitting element 240 (or the direction from the light emitting element 240 to the light source 220) (such as the thickness direction of the electronic device) can be an annular projection. This can be understood as one end of the generatrix of the incident surface 231 being a certain distance from the rotation center line. Alternatively, if the incident surface 231 includes multiple second regions 2311, then a hole may be included between two opposing second regions 2311.

[0221] In some embodiments, the first reflective surface 2331 and the second reflective surface 2332 are coated with a reflective film (e.g., an aluminum film, a silver film, a gold film, etc.) to achieve the light reflection effect of the first reflective surface 2331 and the second reflective surface 2332.

[0222] In some embodiments, except for the incident surface 231 and the exit surface 232, the other surfaces of the light guide 230 are coated with a reflective film (e.g., aluminum film, silver film, gold film, etc.) to limit the transmission of light in the light guide 230 and prevent light leakage.

[0223] In some embodiments, the non-optical surfaces of the light guide 230 (the remaining surfaces other than the incident surface 231, the exit surface 232, the first reflecting surface 2331, and the second reflecting surface 2332) are coated with a black absorption film, so that the light irradiated onto the non-optical surfaces is absorbed and light transmission is prevented.

[0224] In some embodiments, referring to FIG5, the minimum distance between the light source 220 and the light guide 230 in the first direction is greater than 0. This can be understood as the light guide 230 having a certain distance from the light source 220 at any position in the first direction. This ensures that the light guide 230 has sufficient dimensions to facilitate the design of the optical path.

[0225] In other embodiments, referring to FIG7 or FIG10, the light guide 230 may have a receiving groove 234 on the side facing the light source 220, and at least a portion of the light source 220 may be disposed in the receiving groove 234. For example, the aforementioned second region 2311 may be disposed on the bottom wall of the receiving groove 234. By providing a receiving groove 234 for accommodating the light source 220 on the light guide 230, the size of the light-emitting component 200 in the first direction can be reduced, which is beneficial for achieving thinner and smaller dimensions.

[0226] In some embodiments, the light guide 230 can be a single lens (i.e., a single optical element) or a composite lens (composed of two or more single lenses bonded together). In this case, the installation and fixation of the light guide 230 is more convenient. For example, the light guide 230 can have a flange for connection to the decorative element 210. Exemplarily, referring to FIG. 5, the side surface of the flange facing the light emitting element 240 can be used for connection to the decorative element 210. Alternatively, referring to FIG. 7, the side surface of the flange facing the light source 220 can be used for connection to the decorative element 210.

[0227] In some embodiments, the light guide 230 can be a rotating body, thus enabling annular light emission.

[0228] In this application, the term "convex surface" in the aforementioned embodiments refers to the fact that when viewed from the direction in which light is incident on the surface / region, the surface / region appears to bulge outwards, that is, it protrudes away from the direction of light incidence. If the light guide 230 is a single lens or a compound lens, "convex surface" can also be understood as the surface / region appearing to bulge outwards when viewed from the outside of the light guide 230 towards the inside of the light guide 230.

[0229] In this application, the term "concave surface" in the aforementioned embodiments (such as the first reflecting surface 2331, the second reflecting surface 2332, the first region 233a, etc.) means that when viewed from the direction in which light is incident on the surface / region, the surface / region appears concave, that is, concave in the direction of light incidence. If the light guide 230 is a single lens or a compound lens, "concave surface" can also be understood as meaning that when viewed from the outside of the light guide 230 to the inside of the light guide 230, that part of the surface / region appears to be curved outwards.

[0230] In other embodiments, the light guide 230 may be a lens system comprising a plurality of relatively independent lenses, wherein adjacent lenses may have a gap or be fitted together.

[0231] In some embodiments, the light guide 230 can be connected to the decorative element 210 by means of bonding, riveting, welding, snap-fitting, etc. By way of example and not limitation, referring to FIG5 or FIG7, the light guide 230 can be bonded to the decorative element 210 by adhesive 270.

[0232] In some embodiments, the color temperature and / or brightness of the light emitted by the light source 220 are adjustable. This allows the supplementary light to be adjusted to a suitable color temperature and / or brightness according to the actual environmental conditions or user needs, thereby maximizing the relief of visual fatigue and improving the user experience.

[0233] As an example, the light source 220 may include at least one light-emitting device, and when the light-emitting device is configured to have a variable drive current or a variable number of light-emitting devices operating simultaneously, the brightness of the light emitted by the light source 220 can be adjusted.

[0234] For example, the brightness of the light source 220 can be adjusted by regulating the driving current of the light-emitting device or by adjusting the number of light-emitting devices operating simultaneously. Generally, under the condition that other factors remain unchanged, the greater the driving current of the light-emitting device, the higher the brightness of the light source 220; the more light-emitting devices operating simultaneously, the higher the brightness of the light source 220.

[0235] As another example, referring to Figure 12(a), the light source 220 may include a first type of light emitter 221 and a second type of light emitter 222. The first type of light emitter 221 and the second type of light emitter 222 have different color temperatures, and the first type of light emitter 221 and the second type of light emitter 222 are driven separately, so that the color temperature of the light emitted by the light source 220 can be adjusted.

[0236] For example, taking a first type of light emitter 221 having a fixed first color temperature (e.g., 2700 Kelvin) and a second type of light emitter 222 having a fixed second color temperature (e.g., 4500 Kelvin) as an example, when the driving current of the first type of light emitter 221 and the driving current of the second type of light emitter 222 are the same, the light source 220 can have at least the following three color temperature levels: 1) Only the first type of light emitter 221 emits light, and the color temperature of the light emitted by the light source 220 is the same as the first color temperature, such as 2700 Kelvin; 2) Only the second type of light emitter 222 emits light, and the color temperature of the light emitted by the light source 220 is the same as the second color temperature, such as 4500 Kelvin; 3) Both the first type of light emitter 221 and the second type of light emitter 222 emit light, and the color temperature of the light emitted by the light source 220 is between the first color temperature and the second color temperature.

[0237] It is understandable that if the number of light-emitting devices working simultaneously varies at different color temperature levels, the brightness of the light source 220 can also be adjusted.

[0238] It should be noted that, for the purpose of illustrating the positions of the first type of light emitter 221 and the second type of light emitter 222, the opaque area 242 of the light-emitting element 240 in Figure 12(a) has been made transparent. However, this does not mean that the first type of light emitter 221 and the second type of light emitter 222 can be seen by the user. The actual appearance seen by the user can be referred to as shown in Figure 12(b), where the first type of light emitter 221 and the second type of light emitter 222 are covered by the opaque area 242 and cannot be seen by the user.

[0239] As yet another example, still referring to Figure 12(a), the light source 220 may include a first type of light emitter 221 and a second type of light emitter 222, the first type of light emitter 221 and the second type of light emitter 222 having different color temperatures, and the first type of light emitter 221 and the second type of light emitter 222 being driven separately, wherein the current used to drive the first type of light emitter 221 is adjustable and / or the current used to drive the second type of light emitter 222 is adjustable.

[0240] The light source 220 includes light emitters with different color temperatures, and the driving current of the light emitters with different color temperatures is adjustable. Therefore, the brightness and color temperature of the light source 220 can be adjusted by adjusting the current of the light emitters. For example, the brightness of the light source 220 can be adjusted under the same color temperature, or the color temperature of the light source 220 can be adjusted under the same brightness, or the brightness and color temperature of the light source 220 can be adjusted simultaneously.

[0241] Taking a first type of light emitter 221 having a fixed first color temperature and a second type of light emitter 222 having a fixed second color temperature as an example, the color temperature of the light source 220 can be adjusted by changing the ratio of the driving current of the first type of light emitter 221 to that of the second type of light emitter 222. This is because when the ratio of the driving current of the two types of light emitters is different, the proportion of light emitted by the two types of light emitters in the mixed light is different (i.e., the proportion of light intensity is different), and therefore the color temperature of the mixed light is different. The brightness of the light source 220 can be adjusted by changing the driving current of the first type of light emitter 221 and / or the driving current of the second type of light emitter 222. For example, simultaneously increasing the driving current of the first type of light emitter 221 and the driving current of the second type of light emitter 222 (e.g., by the same increase) can achieve brightness adjustment under the same color temperature conditions. For example, by increasing the driving current of the first type of light emitter 221 while decreasing the driving current of the second type of light emitter 222, or by increasing the driving current of the second type of light emitter 222 while decreasing the driving current of the first type of light emitter 221, color temperature adjustment under the same brightness conditions can be achieved. Furthermore, since the driving currents of the first type of light emitter 221 and the second type of light emitter 222 are adjustable, stepless adjustment of brightness and color temperature can be achieved.

[0242] It should be noted that the "brightness / color temperature of the light source 220" mentioned in this application refers to the brightness / color temperature of the light emitted by the light source 220, that is, the brightness / color temperature of the mixed light formed by the light-emitting devices included in the light source 220 when they are working. Furthermore, the color temperature of the light-emitting device or light-emitting body mentioned in this application refers to the color temperature of the light emitted by the corresponding light-emitting device or light-emitting body. Generally, the color temperature of the light emitted by a type of light-emitting device is fixed, therefore, the color temperature of the light emitted by the light-emitting device can be used as a fixed parameter of the light-emitting device. Therefore, the color temperature of the light-emitting device or light-emitting body mentioned in this application also refers to the color temperature parameter of the corresponding light-emitting device or light-emitting body.

[0243] In some embodiments, the first type of light emitter 221 includes a plurality of first light-emitting devices, wherein at least two of the plurality of first light-emitting devices are driven in series, or each of the plurality of first light-emitting devices is driven individually. If the light-emitting devices in the first type of light emitter 221 are driven in series, the driving current of each of the series-connected first light-emitting devices is the same, and their operating states are the same (i.e., they operate simultaneously or simultaneously not operating). If the light-emitting devices in the first type of light emitter 221 are driven individually, the driving current and operating state of each first light-emitting device can be controlled individually.

[0244] In some embodiments, the second type of light emitter 222 includes a plurality of second light-emitting devices, wherein at least two of the plurality of second light-emitting devices are driven in series, or each of the plurality of second light-emitting devices is driven individually. If the light-emitting devices in the second type of light emitter 222 are driven in series, the driving current of each of the series-connected second light-emitting devices is the same, and their operating states are the same (i.e., they operate simultaneously or simultaneously not operating). If the light-emitting devices in the second type of light emitter 222 are driven individually, the driving current and operating state of each second light-emitting device can be controlled individually.

[0245] When light-emitting devices are driven in series, multiple light-emitting devices can be driven by the same driving circuit, which simplifies the driving circuit design. When light-emitting devices are driven individually, the driving current of each light-emitting device is controlled independently, which can increase the brightness and color temperature adjustment range of the light source 220.

[0246] In some embodiments, the color temperature of the first type of light emitter 221 is greater than or equal to 1500 Kelvin (K) and less than or equal to 6500 K. For example, the color temperature of the first light emitter 221 can be in the range of 2700 K-3000 K, which can be used to emit warm white light. Alternatively, the color temperature of the first light emitter 221 can be in the range of 4000 K-5000 K, which can be used to emit natural white light. Alternatively, the color temperature of the first light emitter 221 can be in the range of 6000 K-6500 K, which can be used to emit cool white light.

[0247] In some embodiments, the color temperature of the second type of light emitter 222 is greater than or equal to 1500 Kelvin (K) and less than or equal to 6500 K. For example, the color temperature of the second type of light emitter 222 can be in the range of 2700 K-3000 K, which can be used to emit warm white light. Alternatively, the color temperature of the second type of light emitter 222 can be in the range of 4000 K-5000 K, which can be used to emit natural white light. Alternatively, the color temperature of the second type of light emitter 222 can be in the range of 6000 K-6500 K, which can be used to emit cool white light.

[0248] In some embodiments, the light-emitting component 200 may include a first driving module and a second driving module. The first driving module is used to drive a first type of light-emitting element 221 to emit light, and the second driving module is used to drive a second type of light-emitting element 222 to emit light. In this application, depending on the circuit connection relationship between the light-emitting devices, the first driving module can drive the light-emitting devices in the first type of light-emitting element 221 individually or in series, and the second driving module can drive the light-emitting devices in the second type of light-emitting element 222 individually or in series.

[0249] To make it easier to understand, a more detailed example is given below.

[0250] For example, the first type of light emitter 221 includes two low color temperature light emitters, such as 2700 Kelvin (K), and the second type of light emitter 222 includes two high color temperature light emitters, such as 4500 K. The light intensity of each of these four light emitters can be independently controlled (i.e., the current can be controlled individually, or understood as being driven individually). In its operating mode, the light source 220 can have two high color temperature light emitters and two low color temperature light emitters working simultaneously, with the two low color temperature light emitters maintaining a consistent current and the two high color temperature light emitters maintaining a consistent current. By adjusting the current ratio of the two low color temperature light emitters and the two high color temperature light emitters, the color temperature of the light source 220 (i.e., the color temperature of the mixed light from the four light emitters) can be adjusted. For example, by adjusting the light intensity of the high color temperature light emitters and the low color temperature light emitters, stepless adjustment of the mixed light color temperature can be achieved. The brightness of the light source 220 (i.e., the brightness of the mixed light from the four light-emitting devices) can be adjusted by changing the current of two low color temperature light-emitting devices and / or two high color temperature light-emitting devices. For example, stepless adjustment of the mixed light brightness can be achieved by adjusting the light intensity of the high color temperature light-emitting devices and / or the low color temperature light-emitting devices. Simultaneously increasing the current of two high color temperature devices and two low color temperature devices can achieve brightness adjustment under the same color temperature conditions.

[0251] In some embodiments, the driving current of the first type of light emitter 221 is greater than or equal to 0 and less than or equal to 100 mA. For example, the maximum driving current of the first type of light emitter 221 is 50 mA.

[0252] In some embodiments, the driving current of the second type of light emitter 222 is greater than or equal to 0 and less than or equal to 100 mA. For example, the maximum driving current of the second type of light emitter 222 is 50 mA.

[0253] In some embodiments, the first type of light emitters 221 are centrally symmetrical about the center of the light source 220 or are uniformly distributed around the center of the light source 220. In this way, when all the first type of light emitters 221 emit light, the uniformity of the light emitted by the first type of light emitters 221 can be guaranteed.

[0254] In some embodiments, the second type of light emitters 221 are centrally symmetrical about the center of the light source 220 or uniformly distributed around the center of the light source 220. In this way, when all the second type of light emitters 221 emit light, the uniformity of the light emitted by the second type of light emitters 221 can be guaranteed.

[0255] In this application, the first type of light emitter 221 or the second type of light emitter 222 is centrally symmetrical about the center of the light source 220, which means that the first type of light emitter 221 or the second type of light emitter 222 coincides with itself after rotating 180° around the center of the light source 220.

[0256] For example, the number of light-emitting devices included in the first type of light-emitting body 221 is the same as the number of light-emitting devices included in the second type of light-emitting body 222.

[0257] In some embodiments, the first type of light emitter 221 includes at least one first light emitter, and the second type of light emitter 222 includes at least one second light emitter, with each of the at least one first light emitter being disposed adjacent to one or more of the at least one second light emitter.

[0258] When the first and second light-emitting devices are arranged adjacent to each other, the color mixing can be more uniform when both the first and second light-emitting devices emit light, thereby improving the uniformity of color temperature and brightness.

[0259] In some embodiments, referring to FIG12(a), the first type of light emitter 221 may include two first light-emitting devices, and the second type of light emitter 222 may include two second light-emitting devices. The two first light-emitting devices and the two second light-emitting devices are arranged in a rectangular array, wherein the two first light-emitting devices are diagonally arranged, and the two second light-emitting devices are diagonally arranged. It can be understood that the light source 220 includes four light-emitting devices, which are arranged in a rectangular array, wherein the light-emitting devices on the diagonal of the rectangle are of the same type, such as having the same color temperature.

[0260] Here, four light-emitting devices are arranged in a rectangular array, with low color temperature light-emitting devices and high color temperature light-emitting devices close to each other, so that the light can be fully mixed, thereby achieving a better uniformity.

[0261] In some embodiments, based on the above-described rectangular array arrangement, the light source 220 has at least one of the following modes:

[0262] 1) A first lighting mode, wherein in this first lighting mode, one first light-emitting device and / or one second light-emitting device emits light. This allows the light emitted by the light source 220 to illuminate only half of the environment. For example, when the user is lying on their side, the light source 220 can be in the first lighting mode to avoid the light from being concentrated on the bed surface and creating high contrast due to all light-emitting devices being fully lit, and it also reduces power consumption. Furthermore, when one first light-emitting device and one second light-emitting device are emitting light, the color temperature and brightness can be adjusted while providing illumination.

[0263] 2) Second lighting mode, in which two first light-emitting devices or two second light-emitting devices emit light. In this way, the light emitted by the light source 220 is at the baseline color temperature, that is, the same as the color temperature of the first light-emitting devices or the same as the color temperature of the second light-emitting devices, resulting in good light uniformity.

[0264] 3) Third lighting mode, in which both first and two second light-emitting devices emit light. With all light-emitting devices operating, the color temperature and brightness can be infinitely adjusted by changing the drive current.

[0265] In some embodiments, when the light source 220 is working, the number of light-emitting devices working in the first type of light source 221 is the same as the number of light-emitting devices working in the second type of light source 222, which can avoid uneven color mixing.

[0266] It is understood that in practical applications, the number of the first light-emitting device, the number of the second light-emitting device, and the arrangement of the first and second light-emitting devices can be determined according to actual needs. The rectangular arrangement structure described above is only an example. For example, in other embodiments, the multiple light-emitting devices included in the light source 220 can be arranged in a circular array.

[0267] It can also be understood that the types of light-emitting devices included in the light source 220 are not limited to the first type of light-emitting body and the second type of light-emitting body. In practical applications, the light source 220 may also include the third type of light-emitting body, the fourth type of light-emitting body, etc. with different color temperature parameters. The above is only an example.

[0268] In some embodiments, the light source 220 is used to emit light of one or more colors. For example, a first type of light emitter 221 and / or a second type of light emitter 222 is used to emit light of one or more colors. Exemplarily, if the first type of light emitter 221 or the second type of light emitter 222 is used to emit light of multiple colors, the mixed light can also be of multiple colors, and the supplementary light can be used as an ambient light.

[0269] In some embodiments, when the light source 220 is used to emit light of multiple colors, the multiple colors of light may include at least two of the following: white light (including wavelength ranges of various colors of light), red light (wavelength range of approximately 620 nm to 780 nm), orange light (wavelength range of approximately 590 nm to 620 nm), yellow light (wavelength range of approximately 570 nm to 590 nm), green light (wavelength range of approximately 495 nm to 570 nm), blue light (wavelength range of approximately 450 nm to 495 nm), indigo light (wavelength range of approximately 440 nm to 450 nm), and violet light (wavelength range of approximately 380 nm to 440 nm).

[0270] In some embodiments, the light-emitting device in the light source 220 (such as the aforementioned first light-emitting device or second light-emitting device) can be a light-emitting diode (LED) lamp bead or an organic light-emitting diode (OLED) lamp bead.

[0271] In some embodiments, the light emitted by the light source 220, after being emitted by the light-emitting element 240, has an illumination brightness greater than or equal to 1.1 lux and less than or equal to 17 lux. For example, the illumination brightness of the light source 220 can be greater than or equal to 1.5 lux and less than or equal to 15.4 lux. For instance, the illumination brightness of the light source 220 can be 1.3 lux, 2 lux, 5 lux, 8 lux, 12 lux, 15 lux, or 16 lux, etc. In this application, the illumination brightness range of the light source 220 meets user comfort requirements.

[0272] It should be noted that the illumination brightness of the light source 220 mentioned here refers to the brightness of the central area when the light emitted by the light source 220 illuminates a 1-meter wall surface.

[0273] In some embodiments, the light emitted by the light source 220, after being emitted by the light-emitting element 240, has a color temperature greater than or equal to 1500 Kelvin (K) and less than or equal to 10000 Kelvin. For example, the color temperature of the light source 220 can be greater than or equal to 3000K and less than or equal to 5000K. For instance, the color temperature of the light source 220 can be 1800K, 2200K, 2500K, 2700K, 3300K, 3500K, 3800K, 4200K, 4700K, 4900K, 5500K, 6300K, 7800K, or 9300K, etc. In this application, the color temperature range of the light source 220 can be applied to different scenarios to meet different needs.

[0274] It should be noted that the color temperature of the light source 220 mentioned here refers to the color temperature value measured in a completely dark environment.

[0275] In some embodiments, the light emitted by the light source 220, after being emitted by the light-emitting element 240, has a field of view greater than or equal to 90° and less than or equal to 180°. For example, the field of view of the light source 220 can be greater than or equal to 110° and less than or equal to 180°. Specifically, the field of view of the light source 220 can be 95°, 100°, 105°, 120°, 135°, 150°, 160°, 170°, or 175°, etc. In this application, the light source 220 has a large field of view and a wide light emission range, enabling it to provide soft light.

[0276] In some embodiments, the uniformity of the light emitted from the light source 220 after being emitted by the light-emitting element 240 is greater than or equal to 0.4 and less than or equal to 1. For example, the uniformity of the light source 220 can be 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, or 0.9, etc. In this application, the uniformity of the light source 220 is relatively high, thus the uniformity of the emitted light is good.

[0277] It should be noted that the uniformity of the light source 220 mentioned here is a value obtained by taking into account both brightness uniformity and color temperature uniformity. More specifically, the brightness uniformity of the light source 220 is greater than or equal to 0.6 and less than or equal to 1, and the color temperature uniformity of the light source 220 is greater than or equal to 0.6 and less than or equal to 1.

[0278] In some embodiments, the decorative element 210 can be a dedicated decorative element for the light-emitting component 200, that is, the decorative element 210 is only used to decorate the light-emitting component 200.

[0279] In other embodiments, the decorative element 210 can be a decorative element shared by the light-emitting component 200 and the camera, that is, the decorative element 210 is used to decorate both the light-emitting component 200 and the camera at the same time. In this case, the decorative element 210 is also a camera decorative element. Thus, both the light-emitting component 200 and the camera are disposed within the coverage area of ​​the camera decorative element.

[0280] In some other embodiments, the decorative element 210 can serve as a support component of the light-emitting assembly 200. It can be part of the camera decorative element 105 shown in FIG. 1, or connected to the camera decorative element 105 as a separate part. In this way, the light-emitting assembly 200 and the camera are disposed within the coverage area of ​​the camera decorative element.

[0281] As mentioned above, the decorative element 210 is connected to the housing of the electronic device. For example, the decorative element 210 can be connected to the back cover of the electronic device (e.g., back cover 13 shown in FIG1). For example, the decorative element 210 can be disposed in the DECO area shown in FIG1.

[0282] In some embodiments, the decorative element 210 can be directly connected to the back cover (or back shell) of the electronic device, for example, the decorative element 210 is a dedicated decorative element for the light-emitting component 200.

[0283] In other embodiments, the decorative element 210 can be connected to the back cover of the electronic device via the camera decorative element, that is, the decorative element 210 is directly connected to the camera decorative element, and the camera decorative element is directly connected to the back cover of the electronic device. For example, the camera decorative element can serve as both the light-emitting component 200 and the camera decorative element.

[0284] In some embodiments, referring back to FIG5 or FIG7, the light-emitting component 200 may further include a circuit board 250 electrically connected to the light source 220. The circuit board 250 is used to provide driving current to the light source 220.

[0285] For example, the circuit board 250 can be a rigid circuit board (such as a PCB), a flexible circuit board (such as an FPC), or a rigid-flex circuit board. For instance, the circuit board 250 can be a part of the circuit board 103 in FIG. 1.

[0286] In some embodiments, referring back to FIG5 or FIG7, the light-emitting component 200 may further include a support member 260 for supporting the light source 220. For example, the support member 260 may be a reinforcing plate. Exemplarily, the support member 260 may be connected to a decorative element 210, or to the housing of an electronic device (the back cover 13 shown in FIG1), or to a circuit board 250.

[0287] The above description, in conjunction with Figures 4 to 12, details one type of front-emitting light-emitting component 200. The following description, in conjunction with Figures 13 to 18, details the structure of another type of light-emitting component 300 provided in this application.

[0288] Figure 13 shows a schematic structural diagram of another light-emitting component provided in an embodiment of this application. Figure 14 shows a schematic exploded view of the light-emitting component 300 shown in Figure 13, Figure 15 shows a partial structural schematic diagram of the light-emitting component 300 shown in Figure 13, and Figure 16 shows a cross-sectional schematic diagram of the light-emitting component 300 taken along line EE. The light-emitting component 300 shown in Figures 13 and 14 can be applied to the electronic device 100 shown in Figure 1, 2, or 3, and the light-emitting component 300 can be a specific example of the aforementioned supplementary light 108.

[0289] As shown in Figures 13 and 14, the light-emitting component 300 includes a decorative element 210, a light source 220, a light guide 230, and a light-emitting element 240. The decorative element 210 has a receiving space in which the light source 220 and the light guide 230 are disposed. The decorative element 210 is used to connect to the housing of the electronic device, thus serving to support and fix other components in the light-emitting component 300. A portion of the decorative element 210 is also exposed to the environment, thus also having a decorative effect. The light source 220 is used to emit light; for example, in low-light environments, the light source 220 can provide auxiliary light to the environment to increase the illumination effect and improve ambient light brightness. The light guide 230 is disposed between the light source 220 and the light emitter 240. Referring to the partial structural schematic diagram of the light-emitting component 300 shown in Figure 15, the light guide 230 is disposed around the light source 220 and is used to receive and conduct the light emitted by the light source 220. The light emitter 240 is disposed around the light guide 230 and is connected to the decorative component 210. The light emitter 240 is used to emit light from the light guide 230.

[0290] It should be noted that, in order to make it easier to show the position of the light-emitting element 240, the light-emitting element 240 in Figures 13 and 14 has been made transparent.

[0291] A separate fill light on an electronic device, such as the light-emitting component 300 shown in Figure 13, can provide stable light, thereby improving the brightness of ambient light in low-light environments, reducing the brightness difference between the surrounding environment and the screen, and effectively alleviating eye strain. Furthermore, the separate design of the fill light allows users to control its on / off state as needed, providing a better user experience. For example, in situations with insufficient natural light or dim indoor lighting, the fill light can be turned on for supplementary lighting, photography, illumination, and enhancing ambiance.

[0292] In addition, based on the light-emitting component 300 shown in Figure 13, the light emitted by the light source 220 passes through the light-emitting element 240 and is directed to the side of the light-emitting component 200 to achieve side light emission. The uniformity of the emitted light is better, the range of the light spot formed is larger, and the ambient illuminance can be significantly improved.

[0293] The light-emitting component 300 shown in Figures 13 and 14 differs from the light-emitting component 200 shown in Figures 4 and 5 in that the light-emitting component 200 emits light from the front, while the light-emitting component 300 emits light from the side. Therefore, the light-emitting component 300 and the light-emitting component 200 differ in the structural connection relationship of the light source 220, the light guide 230, and the light-emitting component 240. The differences between the two are described in detail below.

[0294] In some embodiments, the decorative element 210 includes an annular body, and the light-emitting element 240 is embedded in the annular body and extends radially through the annular body. Accordingly, the light-emitting element 240 may form an annular light-transmitting area. In the light-emitting component 300, the annular light-transmitting area is used to emit light to the side of the light-emitting component 300.

[0295] In some embodiments, the light-emitting element 240 and the decorative element 210 are an integral structure formed by a two-material injection molding process.

[0296] In other embodiments, the light-emitting element 240 and the decorative element 210 can be separate components, which can be installed together by bonding or interference fit.

[0297] In some embodiments, to achieve side light emission, referring to FIG16, the light guide 230 is an optical fiber, wherein the end face of the optical fiber faces the light source 220, and the cylindrical surface of the optical fiber has an uneven microstructure. In this way, the light emitted by the light source 220 enters the optical fiber from the end face, can be conducted along the optical fiber, and simultaneously undergoes diffuse reflection on the cylindrical surface of the optical fiber, so that the light is reflected uniformly in all directions, thereby realizing the emission of light from the entire cylindrical surface of the optical fiber, and then incident on the light emitting element 240.

[0298] For example, the cylindrical surface of the optical fiber can be sandblasted to form an uneven microstructure.

[0299] In some embodiments, the light-emitting element 240 may include at least one of the following materials: PC, PMMA, PETG, COC, etc.

[0300] In some embodiments, the light source 220 may include a plurality of light-emitting devices, at least two of which emit light in different directions, so that the light emitted by the light source 220 can form a ring-shaped light and avoid uneven light output.

[0301] In some embodiments, referring to FIG13, FIG14 or FIG16, the light-emitting component 300 further includes a protective lens 280, which is located on one side of the light source 220 in a first direction and connected to the decorative element 210. The protective lens 280 includes an opaque area, and the light source 220 is located within the projection range of the opaque area in the first direction, which is the thickness direction of the electronic device.

[0302] By covering the light source 220 with the protective lens 280, the light source 220 is prevented from emitting light from the side of the protective lens 280, and the light source 220 is not visible from the outside.

[0303] For example, the protective lens 280 can be attached to the decorative element 210 by adhesive 270.

[0304] In some embodiments, referring to FIG17, the electronic device may further include a camera 290, a portion of which is located within a receiving space formed by the decorative element 210, wherein a light source 220 is configured to surround the camera 290. For ease of understanding, FIG18 shows a schematic diagram of the assembly of a portion of the light-emitting assembly 300 with the camera 290. Here, the camera 290 may be a specific example of the camera 106 in FIG1.

[0305] In some embodiments, referring to FIG17, the protective lens 280 may include a light-transmitting area 281 and an opaque area 282, the opaque area 282 being disposed around the light-transmitting area 281, wherein the light-transmitting area 281 is used for light from the subject to pass through to enter the camera 290, and the opaque area 282 is used to cover the light source 220 and the light guide 230.

[0306] In some embodiments, the light-emitting component 300 further includes a circuit board 250 electrically connected to the light source 220. In cases where the electronic device includes a camera 290, the circuit board 250 may be provided with a clearance hole for the camera 290 to pass through, thereby avoiding interference with the mounting of the camera 290.

[0307] In some embodiments, the light-emitting component 300 may further include a support member, such as the support member 260 shown in FIG. 4, which provides support for the light source 220. In cases where the electronic device includes a camera 290, the support member may be provided with a clearance hole for the camera 290 to pass through, thereby avoiding interference with the mounting of the camera 290.

[0308] The embodiments concerning the light source 220 in the light-emitting component 200 are also applicable to the light-emitting component 300. For details, please refer to the relevant description above. For the sake of brevity, they will not be repeated here.

[0309] In addition, embodiments of the light-emitting component 200 that are not contradictory to the light-emitting component 300 can also be applied here. For details, please refer to the relevant description above. For the sake of brevity, they will not be repeated here.

[0310] The structure of the light-emitting component provided in the embodiments of this application has been described in detail above with reference to the accompanying drawings. In the light-emitting component 200 / 300 described above, the light source 220 can be pre-embedded in the DECO area of ​​the electronic device, thereby realizing the integrated design with the industrial design (ID) of the electronic device, which can not only achieve the light emission effect, but also improve the appearance of the electronic device and the user experience.

[0311] In some embodiments, this application also provides a camera module, which includes one or more cameras, a camera trim, and a light-emitting component 200 or 300 as described in the foregoing embodiments. The one or more cameras and the light-emitting component 200 / 300 are disposed within the coverage area of ​​the camera trim. For example, the camera trim can be the camera trim 105 shown in FIG1.

[0312] In some embodiments, this application also provides an electronic device, which includes the light-emitting component 200 or light-emitting component 300 described in the above embodiments.

[0313] In some embodiments, the light emitted by the light-emitting components 200 / 300 exits from the rear housing of the electronic device. For example, the rear housing may be the rear cover 13 shown in FIG. 1.

[0314] In some embodiments, the electronic device further includes a camera trim and one or more cameras. The camera trim is connected to the housing of the electronic device, and the one or more cameras and the light-emitting components 200 / 300 are disposed within the coverage area of ​​the camera trim. For example, the camera trim can be the camera trim 105 shown in FIG1.

[0315] In some embodiments, the one or more cameras and the light-emitting components 200 / 300 may be arranged in an array (such as a rectangular array or a circular array).

[0316] In some embodiments, the electronic device may include a display screen, wherein the display screen and the light-emitting components 200 / 300 are located on opposite sides of the electronic device in the thickness direction. For example, the display screen and the light-emitting components 200 / 300 are located on opposite sides of the mid-frame of the electronic device.

[0317] In some embodiments, the electronic device may include a camera, wherein the camera and the light-emitting components 200 / 300 are located on the same side of the electronic device in the thickness direction. For example, the camera and the light-emitting components 200 / 300 are located on the same side of the mid-frame of the electronic device.

[0318] Figure 19 shows a schematic block diagram of a lighting control method provided in an embodiment of this application. The method 400 shown in Figure 19 is applied to an electronic device, such as the electronic device 100 shown in Figure 1, which includes the light-emitting component 200 or light-emitting component 300 described in the foregoing embodiments. The method 400 includes steps S410 and S420.

[0319] S410 detects the brightness of ambient light.

[0320] This step can be specifically performed by sensors in electronic devices (such as ambient light sensors, light sensors, etc.). These sensors are devices capable of sensing ambient light conditions and converting them into specific numerical values. For example, the output value of the sensor could be the intensity of ambient light, expressed in lux.

[0321] In some embodiments, the sensor can detect light intensity greater than or equal to 0 and less than or equal to 10,000 lux. Thus, the sensor can detect light intensity in different scenarios, such as low-light environments, dimly lit environments, bright environments, and strong light environments.

[0322] For example, the sensor can detect light intensities greater than or equal to 0 and less than or equal to 100 lux. Thus, the sensor is mainly used to detect low-light environments; environments outside its detection range can be considered non-low-light environments, eliminating the need to turn on supplementary lighting and saving power and cost.

[0323] S420, when the first preset condition is met, prompt the user to turn on the auxiliary light source, wherein the first preset condition includes the brightness of the ambient light being less than or equal to a first threshold.

[0324] Here, the auxiliary light source is the fill light 108 described in the foregoing embodiments, which may specifically include a light-emitting component 200 or a light-emitting component 300. In specific applications, the auxiliary light source may also have other names, such as eye-protection light, bright eye mode, etc., which are not limited in this application.

[0325] In this application, the first threshold can be greater than or equal to 30 lux and less than or equal to 50 lux. In practical applications, the first threshold can be determined according to the situation. For example, when the ambient light intensity is less than or equal to the first threshold, the current environment can be considered a dark environment, and it is necessary to turn on the supplementary lighting. When the ambient light intensity is greater than the first threshold, the current environment can be considered a bright environment, and it is not necessary to turn on the supplementary lighting.

[0326] In this application, the electronic device can detect the brightness of ambient light to determine whether it is a dark environment. When the judgment of a dark environment is met, the user is prompted to turn on the auxiliary light source to enhance the ambient light. For example, when the user is using the screen of the electronic device, the brightness of the ambient light is increased to relieve visual fatigue.

[0327] In some embodiments, before step S420, i.e. before prompting the user to turn on the auxiliary light source, method 400 may further include:

[0328] The usage status of the electronic device is detected, and the usage status of the electronic device is used to determine the usage duration of the electronic device. The first preset condition also includes that the usage duration of the electronic device is greater than or equal to the first preset duration.

[0329] In other words, when the ambient light brightness is less than or equal to a first threshold and the usage time of the electronic device is greater than or equal to a first preset time, the electronic device prompts the user to turn on the auxiliary light source. That is to say, when the user is using the electronic device in a low-light environment, the user will be prompted to turn on the auxiliary light source. In this scenario, turning on the auxiliary light source can achieve an eye protection effect and can avoid false reminders when the user is not using the electronic device.

[0330] For example, the first preset duration can be greater than or equal to 3 minutes. In practical applications, the specific value of the first preset duration can be determined according to requirements; this is only an example.

[0331] In some embodiments, before step S420, i.e. before prompting the user to turn on the auxiliary light source, method 400 may further include:

[0332] Detecting sound signals in the environment, wherein the first preset condition further includes determining, based on the sound signals in the environment, that music is being played in the environment and the duration of the music is greater than or equal to a second preset duration.

[0333] In other words, when the ambient light brightness is less than or equal to a first threshold and the music playback duration in the environment is greater than or equal to a second preset duration, the electronic device prompts the user to turn on the auxiliary light source. That is, when a user is listening to music in a low-light environment, they will be prompted to turn on the auxiliary light source; in this scenario, the auxiliary light source can be used as an ambient light.

[0334] For example, the second preset duration can be greater than or equal to 3 minutes. In practical applications, the specific value of the second preset duration can be determined according to requirements; this is only an example.

[0335] There are several ways electronic devices can prompt users to turn on auxiliary lighting.

[0336] As an example, electronic devices can prompt users to turn on auxiliary light sources via voice. For instance, electronic devices can play prompts such as "Please turn on the fill light" or "The current environment is dark, you can turn on the fill light" through a speaker.

[0337] As another example, electronic devices can prompt users to turn on auxiliary light sources through lighting. For instance, users can preset light signals to prompt the user to turn on the fill light, and electronic devices can use light-emitting devices such as front breathing lights to prompt the user.

[0338] As another example, electronic devices can prompt users to turn on auxiliary lighting by displaying floating controls (such as floating boxes, floating icons, etc.) on the current screen.

[0339] For example, referring to Figure 20(a), the electronic device can display a floating window 402 on the current interface 401. This floating window 402 may include a prompt to the user to turn on the fill light, such as "The current environment is dark; do you want to turn on the fill light?". The floating window 402 may also include options to determine the user's intent, such as a "Yes" option to determine if the user currently intends to turn on the fill light, a "No" option to determine if the user does not intend to turn on the fill light, and a "Ask later" option to determine if the user intends to turn on the fill light later.

[0340] For example, as shown in Figure 20(b), the electronic device can display a floating icon 403 on the current interface 401, which is used to prompt the user to turn on the auxiliary light source.

[0341] There are several ways for users to turn on the auxiliary light source.

[0342] In some embodiments, users can turn on the auxiliary light source via a floating control displayed on the current interface of the electronic device.

[0343] As an example, in response to the user's first action on the floating control, the electronic device directly turns on the auxiliary light source, which emits light with default lighting parameters or with lighting parameters adapted to the current environment.

[0344] Here, the default lighting parameters are pre-configured by the electronic device and are used to emit light when the user does not actively adjust the lighting parameters of the fill light. The lighting parameters adapted to the current environment can be determined in real time by the electronic device based on the detected ambient light brightness information.

[0345] For example, in response to a user clicking the "Yes" option in the floating box 402 shown in Figure 20(a), the electronic device can directly turn on the fill light. Similarly, in response to a user clicking the floating icon 403 shown in Figure 20(b), the electronic device can directly turn on the fill light.

[0346] As another example, in response to a user's first action on the floating control, the electronic device can display a first interface, which includes a switch for turning the auxiliary light source on or off.

[0347] For example, when a user clicks the "Yes" option in the floating box 402 shown in Figure 20(a), or clicks the floating icon 403 shown in Figure 20(b), the electronic device can jump to the settings interface of the fill light, such as the settings interface 404 shown in Figure 21(a) (an example of the aforementioned first interface). This settings interface 404 may include a switch 405 for turning the fill light on or off. The user can turn on the auxiliary light source, i.e., the fill light, through the switch 405.

[0348] In some embodiments, the auxiliary light source includes a plurality of light-emitting devices, and the method 400 may further include: detecting the orientation of an electronic device; determining the position and number of light-emitting devices used for actual operation among the plurality of light-emitting devices based on the orientation of the electronic device; and driving the light-emitting devices used for actual operation to emit light in response to a user's operation of turning on the auxiliary light source.

[0349] In other words, when the user turns on the auxiliary light source, the electronic device can determine the actual light-emitting device to operate based on the user's posture. This allows the electronic device to adjust its operating state according to the user's posture, saving power while meeting illumination requirements. For example, when the electronic device indicates the user is in a sitting position, it can determine that all light-emitting devices in the auxiliary light source are emitting light to improve light uniformity. Similarly, when the electronic device indicates the user is in a lying position, it can determine that only some light-emitting devices in the auxiliary light source are emitting light. Taking the structure shown in Figure 12(a) as an example, the electronic device can drive either the two light-emitting devices on the left or the two light-emitting devices on the right, avoiding concentrated light on one side of the bed surface to create high contrast. This satisfies the requirement for improved ambient light while saving power.

[0350] In some embodiments, if the illumination parameters of the supplementary light are adjustable, after the supplementary light is turned on, the setting interface 404 is also used to set the illumination parameters of the auxiliary light source. Here, the illumination parameters of the auxiliary light source include at least one of brightness, color temperature, field of view, and lighting mode. For example, referring to Figure 21(b), after the switch 405 is turned on, the setting interface 404 may include at least one of the following: a control 406 for adjusting brightness, a control 407 for adjusting color temperature, a control 408 for adjusting field of view, and a control 409 for adjusting lighting mode.

[0351] For example, the brightness of the auxiliary light source can be adjusted in multiple levels, such as stepless adjustment, through the control 406.

[0352] For example, the color temperature of the auxiliary light source can be adjusted in multiple levels, such as stepless adjustment, through the control 407.

[0353] For example, the field of view of the auxiliary light source can be adjusted in multiple levels, such as stepless adjustment, through the control 408.

[0354] For example, the lighting mode of the auxiliary light source can be adjusted via control 409. For instance, the lighting mode may include a constant-on mode and a flashing mode. In constant-on mode, the auxiliary light source always emits light, which can be used for eye protection or general illumination. In flashing mode, the auxiliary light source flickers, which can be used as an ambient light. Alternatively, the lighting mode may include a monochrome mode and a color mode. In monochrome mode, the auxiliary light source emits light of one color. In color mode, the auxiliary light source emits light of different colors in turn.

[0355] It is understandable that the classification of constant light mode and flashing mode can be combined with the classification of monochrome mode and color mode. That is, users can simultaneously select one of the constant light mode and flashing mode, as well as one of the monochrome mode and color mode, as the final emission mode of the auxiliary light source.

[0356] In some embodiments, users can turn on the auxiliary light source themselves, that is, without using the floating control displayed on the current interface of the electronic device.

[0357] As an example, users can manually open the fill light's settings interface and activate the auxiliary light source through it. For instance, users can open settings interface 404 as shown in Figure 21(a) and activate the auxiliary light source via switch 405. Correspondingly, after activating the auxiliary light source, users can also adjust its illumination parameters through settings interface 404, as shown in Figure 21(b). For details, please refer to the relevant description above; for brevity, further elaboration is omitted.

[0358] As another example, as shown in Figure 22(a), a user can open the control center interface 411 of an electronic device. The control center interface 411 typically includes multiple controls or switches for quick access. For example, the control center interface 411 may include a fill light switch 412, which the user can operate to turn on the auxiliary light source.

[0359] In some embodiments, in response to a user's operation on the fill light switch 412, such as a long press, the electronic device can display a parameter adjustment interface 413. The parameter adjustment interface 413 is used to set the illumination parameters of the auxiliary light source, wherein the illumination parameters of the auxiliary light source include at least one of brightness, color temperature, field of view, and lighting mode. For example, the parameter adjustment interface 413 may include at least one of a control 406 for adjusting brightness, a control 407 for adjusting color temperature, a control 408 for adjusting field of view, and a control 409 for adjusting lighting mode. A description of controls 406, 407, 408, and 409 can be found in the relevant description in the setting interface 404; for brevity, it will not be repeated here.

[0360] In some embodiments, method 400 may further include: displaying a second interface in response to a user's operation, the second interface being used to set illumination parameters of an auxiliary light source, wherein the illumination parameters of the auxiliary light source include at least one of brightness, color temperature, field of view, and lighting mode. For example, the second interface may be the aforementioned setting interface 404 or parameter adjustment interface 413.

[0361] In some embodiments, the second interface includes at least one of a control for adjusting brightness (such as control 406 described above), a control for adjusting color temperature (such as control 407 described above), a control for adjusting the field of view (such as control 408 described above), and a control for adjusting the lighting mode (such as control 409 described above). The auxiliary light source emits light with a first illumination parameter. The method 400 may further include: adjusting the auxiliary light source to emit light with a second illumination parameter in response to the user's operation on the second interface. Here, the user's operation on the second interface may include at least one of the operation on the control for adjusting brightness, the operation on the control for adjusting color temperature, the operation on the control for adjusting the field of view, and the operation on the control for adjusting the lighting mode.

[0362] In some embodiments, when the auxiliary light source is in an emitting state, method 400 may further include: detecting the emitting temperature of the auxiliary light source; and reducing the brightness of the auxiliary light source when the emitting temperature of the auxiliary light source exceeds a second threshold. For example, an electronic device may reduce the brightness of the auxiliary light source by reducing the driving current of the auxiliary light source.

[0363] For example, the second threshold may be less than or equal to 45°C, such as 35°C. In practical applications, the second threshold can be determined according to requirements; this is only an example.

[0364] The temperature control solution ensures that users can meet safety regulations when using auxiliary light sources for extended periods.

[0365] In some embodiments, method 400 further includes: automatically turning off the auxiliary light source when a second preset condition is met; wherein the second preset condition includes at least one of the following:

[0366] The ambient light intensity is greater than or equal to the third threshold;

[0367] The electronic device is in a screen-off state;

[0368] The duration during which the electronic device maintains the first posture is greater than or equal to the third preset duration;

[0369] The screen of the electronic device is either in a loop or stuck on the last frame of the content being viewed.

[0370] For example, when the ambient light intensity is greater than or equal to a third threshold, the environment can be considered a bright environment, eliminating the need for an auxiliary light source. Therefore, the auxiliary light source can be automatically turned off, saving power. For instance, the third threshold can be greater than or equal to 50 lux, such as 100 lux. In practical applications, the third threshold can be determined according to requirements; this is merely an example.

[0371] For example, when an electronic device is in a screen-off state, it can be assumed that the user is not using the electronic device and there is no need to use the auxiliary light source. Therefore, the auxiliary light source can be automatically turned off to save power consumption.

[0372] For example, if the electronic device maintains the first posture for a duration greater than or equal to a third preset duration, it can be assumed that the user is asleep or not using the electronic device, and therefore the auxiliary light source is not needed. Thus, the auxiliary light source can be automatically turned off, saving power. For instance, the third preset duration can be greater than or equal to 3 minutes, such as 5 minutes. In practical applications, the third preset duration can be determined according to requirements; this is merely an example.

[0373] For example, when the screen of an electronic device is in loop playback or is stuck on the last frame of the content being viewed, it can be assumed that the user is asleep or not using the electronic device, and therefore no auxiliary light source is needed. Thus, the auxiliary light source can be automatically turned off to save power.

[0374] In some embodiments, the second preset condition includes the electronic device being in a screen-off state. If the second preset condition is met, the electronic device can turn off the auxiliary light source after a fourth preset time period.

[0375] When the electronic device is in a screen-off state, the auxiliary light source will be turned off after a certain period of time, so that users can continue to use the device after temporarily turning off the screen or make it easier for users to use the auxiliary light source for illumination.

[0376] For example, the fourth preset duration can be greater than or equal to 3 minutes, such as 5 minutes. In practical applications, the fourth preset duration can be determined according to requirements; this is only an example for illustration.
