[0039] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is only for explaining specific embodiments and is not intended to limit the application. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0040] Portable electronic devices, such as mobile phones, are usually equipped with a flash to assist the camera in capturing images or to perform other functions such as a flashlight. In addition, to better meet user needs, most mobile phones also have infrared lights to support functions such as infrared remote control.
[0041] See Figure 1 This is a schematic diagram of a common layout for flashlights and infrared lights, such as... Figure 1 As shown, the flash and infrared LED are respectively located in the DECO area on the back of the phone. The flash uses an anode drive method and is connected to the flash anode drive chip on the phone's motherboard via an FPC. The infrared LED uses a cathode drive method and is connected to the infrared LED cathode drive chip on the phone's motherboard via an FPC.
[0042] In this layout, the flash driver chip and the infrared driver chip are set up independently. The flash and the infrared lamp are each connected to the corresponding driver chip through an FPC. On the one hand, this requires more space, and on the other hand, it requires more components, resulting in higher costs.
[0043] In addition to accommodating flash and infrared lights, the DECO area typically also needs to house laser lights, flicker sensors, and multiple cameras, making space extremely limited. Infrared lights and flashes, placed independently within the DECO area, require a significant amount of space.
[0044] Based on this, embodiments of this application provide a light-emitting component that saves device space and reduces costs through integrated design.
[0045] The light-emitting component provided in this application can be applied to portable electronic devices such as mobile phones and tablets. For ease of explanation, the technical solution of this application will be illustrated below using a mobile phone as an example.
[0046] Figure 2 This is a schematic diagram of the layout of the light-emitting components in the electronic device provided in the embodiments of this application, such as... Figure 2 As shown, the electronic device may include: a light-emitting component 1 and a camera 2.
[0047] It is understood that electronic devices may also include other components, such as a motherboard, and various other components mounted on the motherboard, including a processor, memory, camera 2, speaker, receiver, microphone, indicator, and sensor. This application does not impose any particular limitation on the specific structure of the electronic device.
[0048] Camera 2 is used to capture still images or videos, and it can be positioned in the DECO area on the back of the electronic device. It is understood that the DECO area can be as follows: Figure 3 As shown, the DECO area is located near the left side of the electronic device, but it can also be located in other positions, such as the middle of the upper half of the back of the electronic device. This application embodiment does not specifically limit the location of the DECO area.
[0049] In some implementations, the electronic device may include one or more cameras 2.
[0050] Figure 3 This is a schematic diagram of the structure of the light-emitting component provided in the embodiments of this application, such as... Figure 2 and Figure 3 As shown, in this embodiment, the light-emitting component 1 may include a light-emitting module 10 and a driver chip 20. The light-emitting module 10 may include a flash lamp 101 and an infrared lamp 102. The driver chip 20 may include a first output terminal D1 and a second output terminal D2. The first output terminal D1 is electrically connected to the first pole of the flash lamp 101 and is used to output a flash lamp driving signal to the flash lamp 101. The second output terminal D2 is electrically connected to the first pole of the infrared lamp 102 and is used to output an infrared lamp driving signal to the infrared lamp 102. The first pole of the flash lamp 101 and the first pole of the infrared lamp 102 have the same polarity, that is, the flash lamp 101 and the infrared lamp 102 adopt the same polarity driving method.
[0051] The light-emitting module 10 can be arranged in the DECO area on the back of the electronic device, and it can be located on either side of the camera 2.
[0052] In the light-emitting module 10, the flash 101 can emit visible light. In some examples, the flash 101 can be used in conjunction with the camera 2. For example, when the electronic device is in a low-light environment, the flash 101 can be turned on to provide illumination for the camera 2, thereby improving the quality of the image captured by the camera 2. In other examples, the flash 101 can also be used to support other functions of the electronic device, such as a flashlight function.
[0053] Infrared lamp 102 emits infrared light. In some examples, infrared lamp 102 can be used to realize infrared remote control function, enabling electronic devices to control devices such as televisions and air conditioners via infrared remote control. In other examples, infrared lamp 102 can also be used to realize other functions, such as infrared ranging function.
[0054] The light-emitting module 10 has a light-emitting direction that the flash lamp 101 and infrared lamp 102 can face the back of the electronic device. In this way, when the user is facing the screen of the electronic device, the light-emitting module 10 can directly aim at the object being illuminated or the remotely controlled device. The user can then operate the device while facing the screen, making the operation more convenient and improving the user experience.
[0055] The light-emitting module 10 can be connected to the driver chip 20 via an FPC. That is, one end of the FPC can be connected to the first output terminal D1 and the second output terminal D2 of the driver chip 20, respectively, and the other end can be connected to the flash lamp 101 and the infrared lamp 102 in the light-emitting module 10, respectively.
[0056] In some embodiments, the flash lamp 101 and the infrared lamp 102 in the light-emitting module 10 are both independent packaged structures, and the two can be set close together to facilitate circuit connection.
[0057] In other embodiments, the light-emitting module 10 can be a packaged module integrating a flash lamp 101 and an infrared lamp 102, that is, the flash lamp 101 and the infrared lamp 102 are integrated in a single packaged structure. This can save space more effectively.
[0058] Both the flash lamp 101 and the infrared lamp 102 can be light-emitting diode (LED) chips to improve integration and extend service life.
[0059] Figure 4 This is a schematic diagram of the component layout of the light-emitting module provided in the embodiments of this application, as shown below. Figure 4 As shown, the packaged module corresponding to the light-emitting module 10 may include: a flash chip (i.e., the LED chip corresponding to the flash 101) and an IR chip (i.e., the LED chip corresponding to the infrared lamp 102).
[0060] The positional relationship between the flash chip and the IR chip can be set as needed. Here, for example, the IR chip is located to the right of the flash chip.
[0061] To improve safety, in some embodiments, a Zener diode can also be integrated into the package module. The Zener diode is connected in parallel with the flash lamp 101 and the infrared lamp 102 to play a role in voltage regulation and overvoltage protection, thereby improving the safety of the operation of the flash lamp 101 and the infrared lamp 102.
[0062] Zener diodes can also be used in chip form to improve integration. For example... Figure 4 As shown, the packaging module may also include a Zener chip (i.e., a Zener diode chip).
[0063] The positional relationship of the Zener chip, flash chip, and IR chip can be set according to the chip size to better save space. For example, here both the IR chip and the Zener chip are located to the right of the flash chip, with the Zener chip below the IR chip.
[0064] Figure 5 (a) in the middle is Figure 4 A rear view diagram of a mid-mounted module. Figure 5 (b) in the diagram is an equivalent circuit diagram of the packaged module. For example... Figure 5 As shown, the back of the package module may include multiple pads 103. The anode FL+ and cathode FL- of the flash chip (i.e., flash 101) and the anode IR+ and cathode IR- of the infrared chip (i.e., infrared lamp 102) can be connected to the pads 103 respectively, and then connected to the FPC through the pads 103, and then connected to the driver chip 20.
[0065] Understandably, when the packaged module includes a Zener diode, Figure 5 The circuit shown in (b) may include a Zener diode, which may be connected in parallel across the two ends of the flash lamp 101 and the two ends of the infrared lamp 102.
[0066] In some embodiments, the anode and cathode of the flash lamp 101 and the infrared lamp 102 can be respectively connected to a pad 103.
[0067] Considering that the operating current of the flash lamp 101 is relatively large, in some embodiments, the anode and cathode of the flash lamp 101 can be connected to multiple pads 103 respectively to improve heat dissipation and current carrying capacity.
[0068] For example, such as Figure 5 As shown in (a), the anode FL+ and cathode FL- of the flash lamp 101 are connected to two pads 103 respectively, and the anode IR+ and cathode IR- of the infrared lamp 102 are connected to one pad 103 respectively.
[0069] As mentioned above, the flash lamp 101 and the infrared lamp 102 are driven by the same polarity. Taking the example that both the flash lamp 101 and the infrared lamp 102 are driven by the anode, the cathodes of both the flash lamp 101 and the infrared lamp 102 are grounded. In this case, the cathodes of the flash lamp 101 and the infrared lamp 102 can also be connected to the same pad 103 (referred to as the common pad) and grounded through the pad 103.
[0070] For example, Figure 6 (a) in the middle is Figure 4 Another rear view diagram of the in-package module. Figure 6 (b) in the diagram is another equivalent circuit diagram of the packaged module. For example... Figure 6 As shown, the anode FL+ of flash lamp 101 and the anode IR+ of infrared lamp 102 are connected to different pads 103, respectively. The cathode FL- of flash lamp 101 and the cathode IR- of infrared lamp 102 are connected to a common pad 103, through which they are grounded. See also Figure 6 In (b), it is equivalent to connecting the cathode IR- of the infrared lamp 102 to the cathode FL- of the flash lamp 101.
[0071] The common pad 103 connected to the flash lamp 101 and the infrared lamp 102 can be one or more, such as Figure 6 As shown, here for example, there are 3 common pads 103.
[0072] In other examples, both the flash lamp 101 and the infrared lamp 102 can be cathode driven. Correspondingly, the anodes of the flash lamp 101 and the infrared lamp 102 can be connected to the same pad 103, through which the power supply is connected.
[0073] See also Figure 3 The driver chip 20 can output a flash drive signal to the flash 101 through the first output terminal D1 to control the working state of the flash 101. For example, it can control the flash 101 to turn on or off, or control the brightness and working mode (such as constant light mode, flashing mode) of the flash 101.
[0074] The driver chip 20 can output an infrared lamp drive signal to the infrared lamp 102 through the second output terminal D2 to control the working state of the infrared lamp 102. For example, it can control the infrared lamp 102 to turn on or off, or control the infrared lamp 102 to emit a specific encoded infrared signal, etc.
[0075] As mentioned earlier, the first output terminal D1 is electrically connected to the first pole of the flash lamp 101, and the second output terminal D2 is electrically connected to the first pole of the infrared lamp 102. The first poles of the flash lamp 101 and the infrared lamp 102 have the same polarity; that is, the flash lamp 101 and the infrared lamp 102 use a same-polarity driving method. This improves integration while reducing circuit complexity and saving costs.
[0076] In some implementations, see Figure 7 The first electrode can be the anode, that is, the flash lamp 101 and the infrared lamp 102 adopt the anode driving method, and correspondingly, the cathodes of the flash lamp 101 and the infrared lamp 102 can be grounded. In this way, the static electricity outside the flash lamp 101 and the infrared lamp 102 can be directly discharged to the ground through the cathode, thereby reducing the impact of static electricity on the light-emitting component 1 and improving the stability of the light-emitting component 1.
[0077] Correspondingly, the driver chip 20 can provide driving voltage to the flash lamp 101 and the infrared lamp 102 through the first output terminal D1 and the second output terminal D2, wherein the driving voltage of the flash lamp 101 and the infrared lamp 102 can be different.
[0078] When the cathodes of the flash lamp 101 and the infrared lamp 102 are grounded, they can be connected to the reference ground (GND) of the electronic device motherboard through FPC or other means.
[0079] In some embodiments, the first electrode can also be a cathode, that is, the flash lamp 101 and the infrared lamp 102 can also be driven by a cathode, and correspondingly, the anode of the flash lamp 101 and the infrared lamp 102 can be connected to a power supply.
[0080] In some embodiments, see Figure 7 The light-emitting component 1 may further include: a flash control module 30 and an infrared lamp control module 40; the flash control module 30 is electrically connected to the driver chip 20 and is used to output a flash control signal to the driver chip 20; the infrared lamp control module 40 is electrically connected to the driver chip 20 and is used to output an infrared lamp control signal to the driver chip 20; the driver chip 20 is used to output a flash drive signal through the first output terminal D1 according to the flash control signal 101, and to output an infrared lamp drive signal through the second output terminal D2 according to the infrared lamp control signal 102.
[0081] Specifically, the driver chip 20 can integrate a flash drive channel and an infrared lamp drive channel. The flash control module 30 can be connected to the first control terminal G1 of the driver chip 20. The first control terminal G1 outputs a flash control signal in the form of a level or pulse to the driver chip 20 to control the flash drive channel in the driver chip 20 to work and generate the corresponding flash drive signal.
[0082] The infrared lamp control module 40 can be connected to the second control terminal G2 of the driver chip 20. It outputs an infrared control signal in the form of level or pulse to the driver chip 20 through the first control terminal G2 to control the infrared lamp driving channel in the driver chip 20 to work and generate the corresponding infrared lamp driving signal.
[0083] Optionally, both the flash control module 30 and the infrared lamp control module 40 can be in chip form to further save space. The flash control module 30 and the infrared lamp control module 40 can be independent chips or integrated into the same chip.
[0084] The above description primarily uses the example of a single flash lamp 101 included in the light-emitting module 10. In other embodiments, the light-emitting module 10 may also include multiple flash lamps 101. Correspondingly, the driver chip 20 may include multiple first output terminals D1, and each flash lamp 101 may be connected to one first output terminal D1. The driver chip 20 can output a driving signal to the corresponding flash lamp 101 through the first output terminal D1.
[0085] Accordingly, each flash unit 101 can correspond to a flash control module 30, or the flash control modules 30 of each flash unit 101 can be integrated together. The specific implementation can be chosen according to needs, and this embodiment does not impose any particular limitation on this.
[0086] It is understandable that the light-emitting component may also include other components, such as the driver chip 20, the flash control module 30, and the peripheral circuits of the infrared control module 40.
[0087] The light-emitting components provided in this application embodiment have an integrated design for the driver chips of the flash lamp and the infrared lamp. Both are driven by the same driver chip, which can reduce the number of driver chips and the number of FPCs required at the same time, thus saving equipment space and reducing costs. In addition, the flash lamp and the infrared lamp adopt the same polarity driving method, which can reduce the circuit complexity of the driver chip, thereby further reducing costs.
[0088] Furthermore, the flash and infrared lights can be integrated into the same package module, which can further save equipment space and reduce costs.
