[0048] The embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments of the present application are mainly to illustrate possible implementation manners of the technical solutions of the present application, and should not be understood as a limitation on the technical solutions of the present application. In the present specification, the same or similar components are indicated by the same or similar reference numerals.

[0049] Figure 1A schematic diagram of the principle of the vehicle light 100 provided in the first embodiment of this application is shown. Figure 2 A schematic diagram of the principle of the vehicle light 100 provided in the second embodiment of this application is shown. Figure 3 A schematic diagram of the principle of the vehicle light 100 provided in the third embodiment of this application is shown. Figure 4 This is a schematic diagram of the first animation or image effect of an example of a vehicle light provided in the first embodiment of this application.

[0050] like Figures 1-3 As shown, the first, second, and third embodiments of this application each provide a vehicle lamp 100, which is used in a motor vehicle 200. The vehicle lamp 100 includes a signal conversion circuit 10, a control circuit 20, and a light source 30. The signal conversion circuit 10 is configured to receive a first signal S1, wherein the first signal S1 includes user-defined first animation or image data. The signal conversion circuit 10 is configured to convert the first signal S1 into a second signal S2 and output the second signal S2. The control circuit 20 is electrically connected to the signal conversion circuit 10. The control circuit 20 may include a microcontroller chip and some peripheral circuits. The control circuit 20 is configured to receive the second signal S2 and output a control signal S3 according to the second signal S2. The light source 30 is electrically connected to the control circuit 20. The light source 30 is configured to switch on and off according to the control signal 30 output by the control circuit 20 to display the user-defined first animation or image in real time.

[0051] It is worth noting that the electrical connection in this application can refer to a direct electrical connection between two components, or an indirect electrical connection between two components through other electronic components or parts. The user typically refers to the driver, passenger, or other person with control over the motor vehicle 200. Figure 4 The first animation or image effect shown is merely exemplary, and the first animation or image in the embodiments of this application may also be of other forms. The specific meaning of the animation and image is not limited, and it includes any display function different from the main lighting or signaling function of the vehicle lights. For example, user-defined welcome animations or images, farewell animations or images, warning animations or images, personalized interactive animations or images, etc. The information in the animation and image may be text, numbers, symbols, logos, images, etc.

[0052] The vehicle headlight 100 of this application embodiment can arbitrarily switch the playback content of the headlight 100 to a user-defined first animation or image in real time according to the user's needs, without being limited by the memory space in the headlight 100. At the same time, it can achieve a more aesthetically pleasing lighting effect, making the motor vehicle 200 more conspicuous and improving safety.

[0053] In embodiments of this application, the light source 30 includes a plurality of LED chips arranged in an array to form a pixelated panel light source. Each LED chip can be controlled independently, thereby achieving corresponding animations or images by controlling the lighting or shutdown of each LED chip. Each LED chip can be an RGB LED chip or a monochrome LED chip, and each LED chip may or may not have an integrated driver.

[0054] In the embodiments of this application, the number of LED chips included in the light source 30 can exceed the approximately 100 chips in a traditional headlight. For example, the number of LED chips in the light source 30 can be greater than 1000, and the light source 30 may include a total of 2000 to 4000 LED chips, thereby avoiding the technical problem of insufficient LED chips leading to poor animation or image effects. However, when the number of LED chips increases, in order to achieve higher brightness, the temperature inside the headlight 100 is easily raised, affecting the normal performance of the headlight 100.

[0055] To address the aforementioned technical issues, the control circuit 20 may include a protection module, which can be a software and / or hardware module within the control circuit 20. The protection module provides a power reference threshold, and the control circuit 20 limits the input power of the light source 30 to be less than or equal to this power reference threshold. The protection module design prevents the light source 30 from overheating when playing animations or images, thus avoiding impacting the overall performance of the vehicle headlight 100. For example, when the amount of user-defined first animation or image data is large, almost all or all of the LED chips in the light source 30 may need to operate under high power conditions for extended periods, easily leading to overheating of the vehicle headlight 100, which is detrimental to its performance. By setting a power reference threshold, the control circuit 20 can adjust the amount of data in the first animation or image to illuminate only a portion of the LED chips, achieving maximum brightness while meeting temperature limits. This achieves both the goal of displaying user-defined animations or images and prevents damage to the vehicle headlight 100 due to high temperatures, effectively balancing the conflict between high brightness requirements and high-temperature limitations. It is worth noting that in practical applications, the input power of the light source can be made to be less than the power reference threshold by adjusting the current or voltage value output to the light source 30.

[0056] Furthermore, in some embodiments, the power reference threshold can be set to include a first power reference threshold and a second power reference threshold, where the first power reference threshold is greater than the second power reference threshold. When the vehicle headlight 100 plays animations or images during the day, the control circuit 20 limits the input power of the light source 30 to be less than or equal to the first power reference threshold. When the vehicle headlight 100 plays animations or images at night, the control circuit 20 limits the input power of the light source 30 to be less than or equal to the second power reference threshold. That is, the maximum brightness of the light source 30 is brighter during the day and dimmer at night. This allows the light source 30 to display a brightness more suitable for human eyes under different ambient light conditions, avoiding excessive brightness of the vehicle headlight 100 at night that could irritate the eyes, thus achieving a better visual experience under different ambient light conditions.

[0057] When the vehicle 200 is in motion, the headlights 100 can be used for lighting or signal indication functions. For example, the headlights 100 can be used as at least one of the following modules: daytime running lights, position lights, turn signals, low beam headlights, high beam headlights, projector lights, brake lights, logo lights, taillights, front fender lights, and rear fender lights. When the vehicle 200 is parked, and not in motion, the headlights 100 can play the user-defined first animation or image in real time according to the user's external control command S7. By integrating animation or image playback functionality into the headlights 100, which have lighting or signal indication functions, the functions of the headlights 100 can be made more diverse, meeting both vehicle lighting regulations and user-defined personalized needs. Furthermore, when the vehicle 200 plays music, the first animation or image can be matched with the music being played. This allows the vehicle to have entertainment functions in addition to its driving function, better meeting the increasing needs of users.

[0058] When the user does not use the custom animation or image function, the vehicle 200 can display some pre-stored animations or images in the headlights 100. For example, when the vehicle 200 is in an unlocked state, locked state, charging state, or vehicle-finding state, the headlights 100 are configured to display animations or images pre-stored in the headlight's memory. Especially in certain scenarios, due to time-sensitive requirements for headlight activation or because vehicle equipment is in sleep mode, users cannot customize animations or images. By pre-stored certain animations or images, some default lighting effects can be configured.

[0059] Specifically, the welcome animation or image data can be pre-stored in the memory of the vehicle lamp 100. When the motor vehicle 200 is in an unlocked state, the vehicle lamp 100 can display the welcome animation or image, such as displaying words like "welcome", "hello", "你好". The farewell animation or image data can also be pre-stored in the memory of the vehicle lamp 100. When the motor vehicle 200 is in a locked state, the vehicle lamp 100 can display the farewell animation or image, such as displaying words like "goodbye", "再见". The charging animation or image data can also be pre-stored in the memory of the vehicle lamp 100. When the motor vehicle 200 is in a charging state, the vehicle lamp 100 can display the charging animation or image. The car-finding animation or image data can also be pre-stored in the memory of the vehicle lamp 100. When the motor vehicle 200 is in a car-finding state, the vehicle lamp 100 can display the car-finding animation or image. In this way, the function of the motor vehicle 200 using the vehicle lamp 100 to interact with the outside can be significantly improved.

[0060] In an embodiment of the present application, as Figures 1-3 shown, an internal memory 21 is integrated inside the micro-control chip of the control circuit 20. The micro-control chip can be an integrated chip such as a microprocessor or an MCU. The internal memory is configured to pre-store the second animation or image data. When the motor vehicle 200 is in a specific state, such as an unlocked state, a locked state, a charging state, or a car-finding state, etc., the control circuit 20 is configured to control the light source 30 to display the second animation or image according to the second animation or image data. This second animation or image data can be, for example, pre-stored in the internal memory 21 by the vehicle manufacturer before the motor vehicle 200 leaves the factory.

[0061] When the user wants to update the second animation or image data, an external control instruction S7 can be issued. The signal conversion circuit 10 receives the first signal S1 corresponding to the user's external control instruction S7. At this time, the first signal S1 includes a first update control signal and the third animation or image data. The control circuit 20 updates the second animation or image data pre-stored in the internal memory 21 to the third animation or image data according to the first update control signal. After the update is completed, when the motor vehicle 200 is in a specific state, the control circuit 20 is configured to control the light source 30 to display the third animation or image according to the third animation or image data. By adding this function in the embodiment of the present application, the motor vehicle 200 can have the function of updating the pre-stored animation or image, and can better meet the personalized needs of users.

[0062] In addition, since the storage space of the internal memory 21 of the micro-control chip is limited, in some embodiments of the present application, as Figures 1-3As shown, an additional external memory 50 can be added outside the microcontroller chip. In this case, the vehicle light 100, in addition to the signal conversion circuit 10, control circuit 20, and light source 30, also includes an external memory 50. The external memory 50 is electrically connected to the control circuit 20. The external memory can be a flash memory, also known as a flash memory, such as common NOR flash or NAND flash. The external memory is configured to pre-store fourth animation or image data. When the vehicle 200 is in a specific state, such as an unlocked state, a locked state, a charging state, or a vehicle-finding state, the control circuit 20 is configured to control the light source 30 to display the fourth animation or image according to the fourth animation or image data. This fourth animation or image data can, for example, be pre-stored in the external memory 50 by the vehicle manufacturer before the vehicle 200 leaves the factory. The external memory 50 can be a non-volatile flash memory (NOR flash). By adding a flash memory, this application can expand the memory of the vehicle light 100, allowing the vehicle light 100 to store more animation or image data, thus solving the problem of insufficient memory in existing microcontroller chips. Furthermore, by integrating the flash memory 50 and the control circuit 20 together onto the main control board of the vehicle light 100, the vehicle light 100 can adapt to harsher working environments due to the high stability of the flash memory 50, and the probability of data loss is significantly reduced.

[0063] When a user wants to update the fourth animation or image data, they can issue a control command. The signal conversion circuit 10 receives a first signal S1 corresponding to the user's external control command S7. At this time, the first signal S1 includes a second update control signal and the fifth animation or image data. The control circuit 20 updates the pre-stored fourth animation or image data in the external memory 50 to the fifth animation or image data according to the second update control signal. After the update is complete, when the vehicle 200 is in a specific state, the control circuit 20 is configured to control the light source 30 to display the fifth animation or image according to the fifth animation or image data. By adding this function, the embodiments of this application enable the vehicle 200 to update pre-stored animations or images, better meeting the user's personalized needs.

[0064] It is worth noting that in some other embodiments, in order to save costs, the additional external memory 50 may not be provided, and this application does not impose any restrictions on this.

[0065] In some embodiments of this application, such as Figure 1 and 3As shown, the vehicle headlight 100 includes a signal conversion circuit 10, a control circuit 20, and a light source 30, as well as a light source driving circuit 40. The light source driving circuit 40 is electrically connected between the control circuit 20 and the light source 30; that is, the control circuit 20 is indirectly connected to the light source 30 through the light source driving circuit 40. The light source driving circuit 40 is configured to receive the control signal S3 via a UART-CAN bus, convert the received control signal S3 into a light source driving signal S4, which can be, for example, a PWM signal and a current / power signal, and output the light source driving signal S4. The light source 30 is configured to switch on and off according to the light source driving signal S4 output by the light source driving circuit 40 to display the user-defined first animation or image in real time. It is worth noting that the control circuit 20 outputs a UART-formatted control signal S3 through the UART port; the vehicle light 200 may further include a UART-CAN conversion circuit, which is connected between the control circuit 20 and the light source driving circuit 40. This UART-CAN conversion circuit is configured to convert the UART-formatted control signal S3 into a CAN-formatted control signal S3, and the light source driving circuit 40 is configured to receive the CAN-formatted control signal S3. Using the CAN-formatted control signal S3 can improve the signal transmission distance.

[0066] In other embodiments of this application, such as Figure 2 As shown, a separate light source driving circuit 40 can be omitted, and instead integrated into the control circuit 20. In this case, the control circuit 20 is directly electrically connected to the light source 30, without needing to go through the light source driving circuit 40. For example, by selecting a microcontroller chip with more integrated functions, the separate light source driving circuit 40 can be eliminated, and its functions can be integrated into the control circuit 20, thus saving more space in the vehicle headlight 100.

[0067] In some embodiments of this application, such as Figures 1-3 As shown, the vehicle headlight 100 also includes a power conversion circuit 60, which is configured to convert the input power signal Pin provided by the vehicle body power supply 230 in the motor vehicle 200 into an output power signal. The output power signal output by the power conversion circuit 60 can power the vehicle headlight 100. The power conversion circuit 60 may include necessary filtering circuits and protection circuits, which will be described in detail here.

[0068] Specifically, in the first and third embodiments, such as Figure 1 and 3As shown, the output power signal includes a first output power signal Pout1, a second output power signal Pout2, and a third output power signal Pout3. The first output power signal Pout1 is used to power the signal conversion circuit 10; the second output power signal Pout2 is used to power the control circuit 20; and the third output power signal Pout3 is used to power the light source driving circuit 40.

[0069] In the second embodiment, as Figure 2 As shown, the output power signal includes a first output power signal Pout1 and a second output power signal Pout2. The first output power signal Pout1 is used to power the signal conversion circuit 10; the second output power signal Pout2 is used to power the control circuit 20. Compared to Figure 1 and Figure 3 The second embodiment does not include a separate light source driving circuit 40, therefore, the output power signal therein does not necessarily include a third output power signal Pout3.

[0070] Embodiments of this application also provide a motor vehicle 200, the motor vehicle 200 including the vehicle lights 100 according to any of the above embodiments.

[0071] Specifically, such as Figures 1-3 As shown, the motor vehicle 200 includes, in addition to the headlights 100, a body control system 210 and a body bus circuit 220. The body control system 210 is configured to output a bus signal S5 according to a user's control command. The body bus circuit 220 is electrically connected to the signal conversion circuit 10 of the body control system 210 and the headlights 100. The body bus circuit 220 is configured to convert the received bus signal S5 into a first signal S1 and output the first signal S1 to the signal conversion circuit 10, thereby controlling the corresponding action of the headlights 100 through the first signal S1.

[0072] In some embodiments, such as Figure 1 and 2As shown, the vehicle body control system 210 is configured to receive external control signals S6 from control software 300 located outside the vehicle 200, and output the bus signal S5 according to the external control signals S6. The control software 300 can run on a mobile terminal, such as a mobile phone, computer, or iPad. The control software 300 can be standalone software running on a mobile terminal, or a mini-program module embedded in other software. For example, a user can transmit customized first animation or image data to the vehicle body control system 210 of the vehicle 200 via mobile software or a WeChat mini-program, and then transmit it to the headlights 100 through the vehicle body control system 210 and the vehicle bus circuit 220, so that the headlights 100 display the user-customized first animation or image. The specific communication method between the control software 300 and the vehicle body control system 210 can be WIFI transmission, 4G / 5G mobile network transmission, or Bluetooth transmission, etc., and this application does not limit this. Third and fifth animation or image data can also be transmitted in the same way, which will not be elaborated here.

[0073] In some other embodiments, such as Figure 3 As shown, the vehicle body control system 210 includes control software 300, which is configured to receive external control commands S7 from the user. Compared to Figure 1 and Figure 2 In the third embodiment, the control software 300 is integrated within the body control system 210, rather than being located on any other carrier outside the vehicle 200. Users can directly download customized first animation or image data through the control software 300 in the body control system 210, and output this customized first animation or image data as at least a part of the bus signal S5 to the body bus circuit 220, which in turn transmits it to the headlights 100, causing the headlights 100 to display the user-customized first animation or image. Third and fifth animation or image data can also be transmitted in the same way, which will not be elaborated further here.

[0074] In some embodiments of this application, the first signal S1 may include a CAN FD message, and the second signal S2 may include serial data or parallel data. The body control system 210 encodes the user's external control command S7 into a CAN FD message, which is output as a bus signal S5. The external control command S7 may include first animation or image data and specific control information. The body bus circuit 220 converts the CAN FD message into a differential voltage, which is then sent as the first signal S1 to the signal conversion circuit 10 of the headlight 100. The body bus circuit 220 can be a domain controller or gateway, which can provide a CAN FD communication bus. The signal conversion circuit 10 can be a CAN FD transceiver, which converts the received differential voltage into 5V TX and RX voltages, and then sends it as the second signal S2 to the microcontroller chip in the control circuit 20. The microcontroller chip then converts the received second signal S2 into a control signal S3. For example, the microcontroller chip can perform data decoding, power adjustment, and other processing on the second signal S2. Thanks to the CAN FD real-time transmission protocol, users can achieve low-latency, high-refresh-rate display of custom animations or images, such as refresh rates up to 40ms / 25fps.

[0075] In some other embodiments, the CAN FD message in the first signal S1 can be replaced with a CANFD message, Lin message, Flexray message, Ethernet message, MOST message, LVDS message, or GMSL. The serial data in the second signal S2 can be replaced with parallel data. By utilizing the existing communication bus in the vehicle 200 to achieve real-time transmission of animation or image data, the functionality of the vehicle lights 100 in the vehicle 200 can be significantly enriched while saving costs.

[0076] Embodiments of this application also provide control software 300, which is configured to receive external control commands S7 from a user and control the headlights 100 of a motor vehicle 200 as described in any of the above embodiments to display the first animation or image customized by the user in real time according to the external control commands S7.

[0077] Current vehicle lights typically cannot directly read animation or image data. The control software 300 can convert the format of the animation or image data into a format that the vehicle lights 100 can read, and then transmit it to the vehicle lights 100 through the vehicle bus circuit 220, so that the vehicle lights 100 can display and play animations or images when needed.

[0078] Although this application has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of this application and should not be construed as limiting this application. The dimensions and proportions in the drawings are merely illustrative and should not be construed as limiting this application.

[0079] While some embodiments of the general concept of this application have been shown and described, those skilled in the art will understand that this application may include many other equivalent embodiments without departing from the general inventive concept of this application, and the scope of protection of this application is defined by the claims.
