Description

Technical Field

[0001] This application relates to the field of lighting control, specifically to a lighting component and a smart terminal. Background Technology

[0002] As users demand a higher level of user experience with electronic devices, more and more mobile devices are equipped with flashlights to improve the lighting environment for easier shooting or illumination.

[0003] In the process of conceiving and implementing this application, the inventors discovered at least the following problems: In order to meet the demand for high-quality imaging, the size of image sensors is getting larger and larger, which leads to the existing cameras occupying a larger and larger area on smart terminals. The area reserved for the flash on the smart terminal is small, and the distance between the flash and the camera is relatively far, resulting in a small light-emitting area and affecting the shooting experience.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the Invention

[0043] The realization of the objectives, functional features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0045] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Optionally, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which needs to be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0046] It should be understood that although the terms first, second, third, etc., may be used herein to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if," as used herein, may be interpreted as "when," "when," or "in response to determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms "comprising," "including," indicate the presence of the stated feature, step, operation, element, component, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used in this application, may be interpreted as inclusive, or mean any one or any combination thereof. For example, "including at least one of the following: A, B, C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Similarly, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Exceptions to this definition only occur when the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0047] It should be understood that although the steps in the flowcharts of this application's embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the sub-steps or stages of other steps.

[0048] Depending on the context, the words “if” or “suppose” as used here can be interpreted as “when” or “in response to determination” or “in response to detection.” Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination” or “in response to determination” or “when detection (of the stated condition or event)” or “in response to detection (of the stated condition or event).”

[0049] It should be noted that step designations such as S11 and S12 are used in this document for the purpose of more clearly and concisely describing the corresponding content, and do not constitute a substantial limitation on the order. In specific implementation, those skilled in the art may execute S12 first and then S11, etc., but these should all be within the protection scope of this application.

[0050] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0051] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0052] Smart terminals can be implemented in various forms. For example, the smart terminals described in this application may include smart terminals such as mobile phones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0053] The following description will use a mobile terminal as an example. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0054] Please see Figure 1 This is a schematic diagram of the hardware structure of a mobile terminal implementing various embodiments of this application. The mobile terminal 100 may include: an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111, etc. Those skilled in the art will understand that... Figure 1 The mobile terminal structure shown does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0055] The following is combined with Figure 1 A detailed introduction to each component of the mobile terminal:

[0056] The radio frequency unit 101 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 110; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, and a duplexer. Furthermore, the radio frequency unit 101 can also communicate wirelessly with networks and other devices. The aforementioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), and 5G, etc.

[0057] WiFi is a short-range wireless transmission technology. Mobile terminals, through the WiFi module 102, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 1 WiFi module 102 is shown, but it is understood that it is not a necessary component of a mobile terminal and can be omitted as needed without changing the nature of the invention.

[0058] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the mobile terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the mobile terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

[0059] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 106. The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0060] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the ambient light level, and the proximity sensor can turn off the display panel 1061 and / or backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0061] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0062] User input unit 107 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110. In addition, touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Optionally, other input devices 1072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0063] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Subsequently, the processor 110 provides corresponding visual output on the display panel 1061 based on the type of touch event. Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

[0064] Interface unit 108 serves as an interface through which at least one external device can connect to mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 108 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within mobile terminal 100, or it may be used to transmit data between mobile terminal 100 and the external device.

[0065] The memory 109 can be used to store software programs and various data. The memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0066] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 110.

[0067] The mobile terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0068] although Figure 1 As not shown, the mobile terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0069] To facilitate understanding of the embodiments of this application, the communication network system on which the mobile terminal of this application is based is described below.

[0070] Please see Figure 2 , Figure 2 This application provides a communication network system architecture diagram. The communication network system is an LTE system based on the universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and the operator's IP services 204, which are connected in sequence.

[0071] Optionally, UE201 can be the aforementioned terminal 100, which will not be described in detail here.

[0072] E-UTRAN202 includes eNodeB2021 and other eNodeB2022, etc. Optionally, eNodeB2021 can connect to other eNodeB2022 via backhaul (e.g., X2 interface), and eNodeB2021 connects to EPC203, providing access from UE201 to EPC203.

[0073] EPC203 may include MME (Mobility Management Entity) 2031, HSS (Home Subscriber Server) 2032, other MMEs 2033, SGW (Serving Gateway) 2034, PGW (Packet Data Network Gateway) 2035, and PCRF (Policy and Charging Rules Function) 2036, etc. Optionally, MME2031 is the control node that handles signaling between UE201 and EPC203, providing bearer and connection management. HSS2032 is used to provide registers to manage functions such as the Home Location Register (not shown in the figure) and stores user-specific information such as service characteristics and data rates. All user data can be sent through SGW2034. PGW2035 can provide UE 201 IP address allocation and other functions. PCRF2036 is the policy and charging control decision point for service data flow and IP bearer resources. It selects and provides available policy and charging control decisions for the policy and charging enforcement function unit (not shown in the figure).

[0074] IP services 204 may include the Internet, intranet, IMS (IP Multimedia Subsystem), or other IP services.

[0075] Although the above description uses the LTE system as an example, those skilled in the art should understand that this application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems (such as 5G), etc., without limitation.

[0076] Based on the above-described mobile terminal hardware structure and communication network system, various embodiments of this application are proposed.

[0077] Example 1

[0078] Please see Figure 3 As shown, a lighting assembly 1 provided in an embodiment of this application includes a conductive element 10, a supplementary light source 20, a first circuit board 30, and a spring contact 40. The supplementary light source 20 is disposed on the conductive element 10. The spring contact 40 is disposed on the first circuit board 30, and the spring contact 40 can selectively contact the conductive element 10 to selectively electrically connect the conductive element 10 and the first circuit board 30.

[0079] When the spring 40 contacts the conductive element 10, the conductive element 10 is electrically connected to the first circuit board 30, so that the supplementary light source 20 is electrically connected to the first circuit board 30, thereby emitting light according to a preset rule under the control of the first circuit board 30, and connecting to a power source through the first circuit board 30.

[0080] Optionally, the supplementary light source 20 can be a traditional supplementary light with a large luminous area and relatively uniform light emission, or it can be at least one of the following: flashlight, laser light, ambient light, and effect light. The number, arrangement, and other aspects of the supplementary light sources 20 can be adaptively set according to the actual application scenario. Some descriptions below provide illustrative examples, but do not constitute a limitation of this application.

[0081] Optionally, the first circuit board 30 can be a control circuit board for the lighting assembly 1. The function and type of the first circuit board 30 can be determined according to actual needs. For example, it may integrate an MCU (Microcontroller Unit) and / or a BMS (Battery Management System). Structural components such as spring contacts 40 are electrically connected to the first circuit board 30 by surface mounting or other methods. Under the control of the MCU, the first circuit board 30 is used to realize, for example, the power connection and power disconnection of the structural components. The first circuit board 30 can be configured separately for the lighting assembly 1, or it can be a circuit board of a smart terminal applicable to the lighting assembly 1, such as the main control circuit board of the smart terminal. Specifically, the first circuit board 30 can be a printed circuit board (PCB) and / or a flexible printed circuit (FPC).

[0082] Optionally, the spring contact 40 may be a switch disposed on the first circuit board 30. Under the control of the first circuit board 30, for example by sending a corresponding electrical signal command, the spring contact 40 can change its orientation toward the conductive element 10 and eventually contact the conductive element 10, thereby making the conductive element 10 electrically connected to the first circuit board 30. The specific forms of the spring contact 40 include, but are not limited to, electrical switches and electro-deformable elements.

[0083] Optionally, the conductive element 10 is used to establish a power connection channel between the supplementary lighting source 20 and the first circuit board 30, and it has at least good conductivity. In some scenarios, the conductive element 10 can be a circuit board, which can be referred to as the second circuit board 10 to distinguish it from the aforementioned first circuit board 30.

[0084] Optionally, the second circuit board 10 can be an FPC, which can be adapted to the internal spatial shape and orientation of the lighting component 1 or the smart terminal to which the lighting component 1 is adapted by changing its shape. Optionally, for Figure 3 In the scenario shown, the second circuit board 10 is positioned above the first circuit board 30. The surface of the first circuit board 30 is provided with multiple electronic components. Based on their different types and functions, these electronic components have different heights (i.e., lengths along the second direction y). The second circuit board 10 can adapt to the shape of the electronic components on the first circuit board 30 by changing its own shape, so that the distance between different positions on the second circuit board 10 and the first circuit board 30 along the second direction y is minimized as much as possible. This is beneficial for controlling the entire lighting assembly 1 and its adapted smart terminal to have a smaller height.

[0085] Optionally, the second circuit board 10 is a rigid circuit board, which can have a preset shape during manufacturing, thus adapting to the internal spatial shape and orientation of the lighting assembly 1 or the smart terminal to which the lighting assembly 1 is adapted. The rigid circuit board can protect the electronic components within its coverage area, preventing the lighting assembly 1 from impacting the electronic components on the first circuit board 30 due to drops or collisions. Of course, the second circuit board 10 can also be a horizontal rigid circuit board. Optionally, the rigid second circuit board 10 is parallel to the first circuit board 30.

[0086] Optionally, the second direction y can be the lighting component 1 or its adapter, such as... Figure 9 The thickness direction of the smart terminal 2 shown is defined. The first direction x is perpendicular to the second direction y, and can be, for example, the width direction of the lighting component 1 or its adapted smart terminal 2. The third direction z can be the length direction of the lighting component 1 or its adapted smart terminal 2. Optionally, the first direction x, the second direction y, and the third direction z are all perpendicular to each other. It should be noted that, due to limitations in actual processing or measurement errors (also known as tolerances), the term "any two perpendicular" as used throughout this application does not require the included angle between the two to be 90°, but rather allows for a deviation of ±10°. That is, "perpendicular" can be understood as the included angle between any two directions being 80° to 100°. Optionally, the term "any two parallel" as used throughout this application also allows for a deviation of, for example, ±10°.

[0087] Optionally, the conductive component 10 can be an antenna, including but not limited to an NFC (Near Field Communication) antenna. The lighting assembly 1 can also have near field communication functionality. When the lighting assembly 1 is adapted to the smart terminal 2, the lighting assembly 1 can utilize the NFC or other antennas already present in the smart terminal 2 to power the supplementary lighting source 20.

[0088] Optionally, the conductive element 10 in any of the aforementioned exemplary embodiments may be disposed on at least one side region of the first circuit board 30. Optionally, along the second direction y, the conductive element 10 and the side region of the first circuit board 30 at least partially overlap. Optionally, in a scenario where the lighting assembly 1 is adapted to the smart terminal 2, along the second direction y, the conductive element 10 may be disposed in a non-display area of ​​the smart terminal 2, such as within the bezel area.

[0089] The so-called side area can be understood as an area with a predetermined length from the side along the direction from the center. The predetermined length can be determined according to the size of the first circuit board 30, for example, the predetermined length can be 0.3cm to 0.5cm. Generally speaking, the side area can be the edge part of the circuit board where no traces or electronic components are set. Along the second direction y, the spring 40 and the conductive element 10 are set in the side area of ​​the first circuit board 30, which can save the layout space of the first circuit board 30 and can also be applied to the component layout method of NFC antennas and other components in the smart terminal 2.

[0090] Optionally, the lighting assembly 1 may also include other structural elements, which are not limited in the embodiments of this application. Optionally, such as Figure 4 As shown, the lighting component 1 may also include a light diffusion component, which is disposed in the light path of the supplementary light source 20 to increase the light transmission angle of the supplementary light source 20.

[0091] Optionally, the light diffusion assembly includes at least one of a light guide plate, a diffusion film, a liquid lens, and an electrodeformable element. Optionally, an electrodeformable element can be understood as a structural element that deforms when energized and adjusts the light transmission angle through this deformation. For example... Figure 4 As shown, the light guide 51 includes a light-incident surface 511 and a light-exit surface 512 that are perpendicular to each other. The light-incident surface 511 is disposed adjacent to the supplementary light source 20, and the light-exit surface 512 is parallel to the optical axis O direction of the supplementary light source 20. The light guide 51 can be used to convert the light emitted from the supplementary light source 20 into surface light, which can be uniformly emitted from the light-exit surface 512. Along the second direction y, the diffusion film 52 at least covers the light guide 51 and optionally covers the supplementary light source 20, for diffusing the light emitted from the light-exit surface 512 of the light guide 51, thereby increasing the light transmission angle.

[0092] In the lighting assembly 1, continuous light emission can be achieved through the contact between the spring 40 and the conductive component 10. By setting an appropriate type of supplementary light source 20, a larger light-emitting area and good light uniformity can be obtained. Optionally, the structural components, including the supplementary light source 20, can be assembled inside the smart terminal 2, eliminating the need for a separate supplementary light device, resulting in low lighting costs and convenient operation.

[0093] The supplementary light source 20 can be used in conjunction with a flash for illumination, or it can be used independently to provide illumination, meeting the lighting needs of scenarios such as photography and reading. The following description, using Example 2, illustrates the combination of the supplementary light source 20 and the flash, including their positions and the principle of their combined illumination.

[0094] Example 2

[0095] Based on the description of Embodiment 1 above, Embodiment 2 uses the same reference numerals to identify structural elements with the same names. Optionally, as... Figures 5 to 8 As shown, the positional relationship between the supplementary lighting source 20 and the flash 60 includes at least one of the following exemplary embodiments:

[0096] Exemplary Implementation 1: The flash lamp 60 is disposed adjacent to the light incident surface 511 of the light guide plate 51. At least a portion of the light emitted by the flash lamp 60 can be converted into surface light by the light guide plate 51, thereby improving the uniformity of the light emitted from the lighting assembly 1. Furthermore, it can emit light together with the supplementary light source 20 to increase the illumination intensity.

[0097] Exemplary Implementation Method 2: Please refer to Figure 5 As shown, the fill light source 20 and the flash 60 are positioned adjacent to each other. For example, the flash 60 can typically be positioned adjacent to the camera module 70, and in this case, the fill light source 20 is also positioned adjacent to the camera module 70, so that the fill light source 20 can be better suited to the shooting lighting needs of the camera module 70. The shape of the fill light source 20 can be as follows: Figure 5 The surface light source shown can also be as follows: Figure 6 The light strip shown is arranged in a rectangular ring.

[0098] Exemplary Implementation 3: The supplementary light source 20 is arranged to at least partially surround the flash 60. For example, as shown in Figure 8, the supplementary light source 20 can be a light bar, which is rectangular and arranged to surround the flash 60 and the camera module 70.

[0099] Exemplary Implementation 4: The supplementary lighting source 20 is provided with a light-transmitting area 20a, which exposes the flash 60 and, of course, the camera module 70. Optionally, please refer to... Figure 7As shown, the fill light source 20 is a surface light source. Along the second direction y, the shape of the light-transmitting area 20a is the same as the shape of the flash 60 and the camera module 70 at the corresponding positions. The fill light source 70 has a large light-emitting area.

[0100] For the supplementary lighting source 70 in any of the above exemplary embodiments, in other scenarios... Figures 5 to 8 The supplementary light source 20 shown can also be the coverage area and / or light emission range of the light diffusion component.

[0101] Example 3

[0102] Based on the description of any of the foregoing embodiments, the difference lies in that the supplementary lighting source 20 of this embodiment 3 includes at least two light-emitting areas 20b, and each light-emitting area 20b can emit light independently. Optionally, please refer to Figure 10 As shown, each light-emitting area 20b is actually a separate light strip, and each light strip is individually connected to the conductive component 10 and emits light according to a preset rule through the control unit on the conductive component 10.

[0103] In scenarios such as rear-facing shooting, the user can fix the smart terminal 2 on a tripod or other fixed device to avoid shaking during shooting. After setting relevant shooting parameters (such as focus distance) and a countdown on the smart terminal 2, the preset feature information of at least two luminous areas 20b changes with the remaining time of the countdown. Since the user is facing the camera module 70 (rear camera 70 in the figure), the user can see the changes in the preset feature information of the fill light source 20 and know the remaining time for shooting based on the changes in the preset feature information. Based on this, the user can choose an appropriate moment to pose for a selfie. When the countdown ends, the rear camera 70 takes the picture, which helps to accurately capture the selfie pose. Selfie poses include, but are not limited to: the user's facial expressions, body movements, and any combination of elements within the environment framed by the rear camera 70. For example, if the user jumps upwards when they know there is one second left in the countdown, the rear camera 70 can capture this scene relatively accurately and can combine facial recognition technology to capture the user's location and complete the image.

[0104] In some embodiments, the preset feature information includes at least one of the following: brightness, color, and luminous area. Optionally, the supplementary light source 20 can change the preset feature information according to a preset duration. The smart terminal 2 can divide the countdown into multiple time periods according to the number of luminous areas 20b. For example, if the countdown is 5 seconds and the preset duration is 1 second, then each type of preset feature information has five variation gradients.

[0105] Taking brightness as an example, the brightness of each light-emitting area 20b of the supplementary light source 20 can gradually increase or gradually decrease, and the user can know the remaining time until the shooting time based on the change in brightness.

[0106] Taking color as an example, each luminous area 20b of the fill light source 20 is displayed as white when there are 5 seconds left, as blue when there are 4 seconds left, as yellow when there are 3 seconds left, as orange when there are 2 seconds left, and as red when there are 1 second left. When the remaining time is 0, i.e., when shooting is performed, the fill light source 20 can be turned off, or it can be switched to the fill light color required for shooting, such as white, to increase the light intensity required for shooting and perform fill light for shooting.

[0107] Optionally, the luminous area can be represented by the number of luminous areas 20b that emit light. Optionally, the supplementary light source 20 includes 5 luminous areas 20b, all 5 luminous areas 20b emit light when there are 5 seconds remaining, and only 4 luminous areas 20b emit light when there are 4 seconds remaining, and the number of luminous areas 20b that emit light decreases according to the countdown.

[0108] Optionally, the aforementioned preset feature information of various types can be combined with each other and change as the countdown timer remains. Taking preset feature information including brightness and luminous area as an example, the fill light source 20 can gradually reduce the luminous area 20b that is turned on as the remaining time decreases, but maintains the brightness unchanged, so as to both remind the user and provide fill light when shooting with the rear camera.

[0109] Optionally, at least two light-emitting regions 20b are arranged along a preset direction, thereby controlling the light emission of each light-emitting region 20b according to the preset direction. Optionally, the preset direction includes at least one of a preset straight line direction, a clockwise direction, and a counterclockwise direction.

[0110] The lighting component 1 in any of the foregoing embodiments can exist as a separate component, thereby allowing for flexible assembly into different types of camera modules 70 or smart terminals 2. This not only facilitates meeting production, sales, and transportation needs but also ensures the compatibility of the lighting component 1, making it easier to popularize. Alternatively, the lighting component 1 can be part of the camera module 70 or the smart terminal 2.

[0111] This application also provides a camera module, including a camera assembly and a light assembly 1 as described in any of the above embodiments, thus having the beneficial effects corresponding to the light assembly 1. Optionally, the camera module can exist as a separate component.

[0112] This application also provides a smart terminal, such as... Figure 9As shown, it includes a camera assembly 70 and a light assembly 1 as described in any of the above embodiments, and therefore has the beneficial effects corresponding to the light assembly 1.

[0113] This application also provides a lighting control method, which can optionally be used with the aforementioned lighting component 1 and / or camera module to achieve the lighting requirements of the corresponding scene. Please refer to... Figure 11 As shown, the lighting control method includes the following steps:

[0114] S11: Determine the target lighting control mode.

[0115] S12: Control the power supply of the fill light source according to the target lighting control mode. The light transmission angle of the fill light source is greater than that of the flash.

[0116] In step S11, the method for determining the target shooting mode is not limited in this embodiment. Three exemplary implementation methods are described below.

[0117] Exemplary Implementation Method 1:

[0118] In response to the selection of a target lighting control mode, the system identifies the target lighting control mode based on the selection operation. Optionally, this selection operation can be a user-issued command, and the command can be issued in ways including but not limited to manual selection, voice commands, air gestures, facial recognition, and password input. For example, with manual selection, a dialog box can be displayed showing options such as "First Lighting Control Mode" and "Second Lighting Control Mode." The user selects the chosen lighting control mode by clicking on one of the options. With password input, each lighting control mode has a corresponding preset password. Optionally, if the user enters a preset first password on the display screen and the password matches successfully, the first lighting control mode is selected. If the user enters a preset second password and the password matches successfully, the second lighting control mode is selected. With facial recognition, pressing a predetermined button defaults to selecting the first lighting control mode, while only when a predetermined face image is detected is the second lighting control mode selected.

[0119] Exemplary Implementation Method 2:

[0120] In response to current scene information, the target lighting control mode is identified based on the current scene information. Optionally, the current scene information is preset information about the scene where the lighting component 1 is currently located. This preset information can be information required for performing lighting, including but not limited to at least one of the following: brightness, type of objects within the shooting range, and location information. For example, when light intensity affecting the shooting effect is detected within the camera's field of view, a first lighting control mode can be determined. For example, when the current location is in a low-brightness position (such as indoors, under a bridge, etc.), a second lighting control mode can be determined.

[0121] Exemplary Implementation Method 3:

[0122] The camera module acquires a preview image, and the target lighting control mode is determined based on the preview image. This includes at least one of the following scenarios: Scenario 1: The user can manually select the target lighting control mode based on the imaging effect of the preview image; Scenario 2: The camera module and / or the terminal determines whether to select the target lighting control mode based on preset information in the preview image. For example, by identifying the number and / or area of ​​dark areas in the preview image, if the number of dark areas exceeds a first quantity threshold and / or the area of ​​dark areas exceeds a first area threshold, the target lighting control mode is determined to be a dark environment shooting mode, thereby selecting a larger aperture 21. As another example, by identifying the number and / or area of ​​bright areas in the preview image, if the number of bright areas exceeds a second quantity threshold and / or the area of ​​bright areas exceeds a second area threshold, the target lighting control mode is determined to be a bright environment shooting mode, thereby selecting a smaller aperture 21.

[0123] According to exemplary embodiment 2 or 3, the lighting control mode can be intelligently selected, and the lighting component 1 can be automatically controlled, resulting in a high degree of intelligence. According to the above exemplary embodiment 1, the lighting control mode can be manually selected, which better meets user needs. It should be understood that exemplary embodiments 1 to 3 can be combined with each other. For example, the device (lighting component 1 and / or smart terminal) can intelligently determine the mode first, and then the mode can be determined manually. The lighting control mode determined manually and intelligently by the device can be different.

[0124] Optionally, the lighting control method further includes: controlling the preset characteristics of the supplementary lighting source to change according to a preset operation. The specific implementation principle and process of this step can be found in the corresponding description of the aforementioned Embodiment 3, and will not be repeated here.
