Description

A vehicle lighting module, a method for controlling vehicle lights, a vehicle lighting system, and a vehicle. Technical Field

[0001] This application relates to the field of intelligent vehicle driving, and more particularly to a vehicle lighting module, a method for controlling vehicle lighting, a vehicle lighting system, and a vehicle. Background Technology

[0002] The emergence of intelligent headlights has endowed the headlights of smart cars with more personalized and scenario-based features. Intelligent headlight modules are no longer limited to mere illumination; they can also project images. To further enhance the effect of projected images, how to enable headlight modules to achieve color projection while fulfilling high-brightness illumination is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] This application provides a vehicle headlight module, a method for controlling vehicle headlights, a vehicle headlight system, and a vehicle. The headlight module provided by this application can achieve color projection display while also ensuring sufficient output brightness when used for lighting functions. Furthermore, the technical solution of this application has high reliability, low process difficulty requirements, is easy to mass-produce, and has low production costs.

[0004] Firstly, a vehicle headlight module is provided. This headlight module includes a light source module, a color wheel module, and a lens module. The light source module emits a first light beam, which is a beam carrying image information. The color wheel module modulates the first light beam according to the image information to generate a second light beam. The second light beam is a beam carrying image information. The lens module emits the second light beam.

[0005] Based on the above solution, a color wheel module in the automotive headlight module modulates the light beam emitted from the light source module, allowing image information to be superimposed onto the emitted beam to achieve color projection. The overall structure is highly stable, has low complexity, is easy to mass-produce, and has low production costs.

[0006] In conjunction with the first aspect, in some implementations of the first aspect, the color wheel module includes a first region and a second region. The color wheel module is used in a first application scenario based on the vehicle headlight module, causing the first light beam to exit through the first region to obtain a second light beam. Alternatively, the color wheel module is used in a second application scenario based on the vehicle headlight module, causing the first light beam to exit through the second region to obtain a second light beam.

[0007] Based on the above solution, the color wheel module has corresponding areas for emitting the light beams emitted by the light source module, according to different application scenarios of the automotive lighting module. Through the color wheel module, different application scenarios of the automotive lighting module are accommodated, allowing the module to meet multiple application needs with a single light source, fulfilling both illumination requirements and color projection. This improves the functionality and user experience of the automotive lighting module, reduces the complexity of the light source and the overall automotive lighting module, and also lowers the production cost of the automotive lighting module.

[0008] It should be understood that the areas included in the first region and the second region may overlap, that is, they may share the same area; or they may be completely different areas; this application does not make any special limitation in this regard.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the headlight module also includes a control module. The control module is used to acquire the application scenario of the headlight module, and according to the application scenario, controls the timing of the first beam emission from the light source module and the position of the color wheel module to ensure the first beam is emitted. The application scenario includes a first application scenario and a second application scenario.

[0010] Based on the above solution, the headlight module also includes a control module. This control module can control the color wheel module and the light source module separately, depending on the application scenario of the headlight module. Specifically, the control module controls the light source module to emit and stop emitting the first beam of light according to the application scenario; the control module also controls the position of the color wheel module to adjust the incident position of the first beam, thereby modulating the first beam. Modulating the beam by controlling the position of the color wheel results in low overall structural and operational complexity and high overall reliability.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, in response to the headlight module being in a first application scenario, the control module is further configured to control the color wheel module to rotate at a first frequency based on image information. The control module is also configured to control the light source module to emit a first beam of light at a first moment. The color information superimposed on the first region into which the first beam of light is incident is the color information included in the image information.

[0012] Based on the above scheme, when the headlight module is in the first application scenario, the control module controls the rotation frequency of the color wheel module according to the image information. Based on the rotation frequency of the color wheel module, the light source module is controlled to emit the first beam of light or stop emitting light according to a specific timing sequence. This utilizes the persistence of vision effect of the human eye to achieve color projection display.

[0013] It should be understood that after the first beam emitted from the light source module is incident on the color wheel module, the color information superimposed on the second beam emitted is all the color information included in the image information. If the color information superimposed on the beam emitted from the light source module is not the color information included in the image information, then the light source module will not emit light at this time.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, in response to the vehicle headlight module switching to a first application scenario or a second application scenario, the control module is also used to drive the color wheel module to translate or rotate along a first direction, so that the incident position of the first beam switches to the first region or the second region.

[0015] Based on the above solution, when the application mode of the headlight module changes, the control module drives the color wheel module to rotate or translate, thereby changing the incident position of the first beam. The mode switching method in this application is simple, low in complexity, and exhibits high overall reliability and stability.

[0016] It should be understood that when the control module drives the color wheel module to translate along the first direction, the first direction includes the horizontal or vertical direction.

[0017] It should be understood that when the control module drives the color wheel module to rotate in a first direction, the first direction includes clockwise or counterclockwise directions.

[0018] As an example and not a limitation, if the color wheel module is in its current position, the incident position of the first beam is the first region. If the first application scenario is activated in response to the headlight module, the control module drives the color wheel module to rotate along the first direction at a specific frequency, and turns the light source module on or off according to a specific timing sequence to achieve color projection of the headlight module.

[0019] As an example and not a limitation, if the color wheel module is in its current position and the incident position of the first beam is the first region, if the second application scenario is activated in response to the headlight module, the control module drives the color wheel module to rotate a certain angle along the first direction and stop, or the control module drives the color wheel module to translate a certain distance along the first direction and stop, so that the first beam emitted by the light source module passes through the first region of the color wheel module.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, in response to the headlight module being in a second application scenario, the control module is also used to acquire the lighting mode of the headlight module and control the color wheel module to stop at a first position or a second position according to the lighting mode.

[0021] In conjunction with the first aspect, in some implementations of the first aspect, when the color wheel module stops at the first position, the first beam passes through the white area. When the color wheel module stops at the second position, the first beam passes through the yellow area.

[0022] Based on the above solution, when the headlight module is in the second application scenario, the color wheel is stopped and no longer rotates, allowing the light beam emitted by the light source module to exit through the second area, achieving monochromatic light emission. Furthermore, the incident position of the first beam can be adjusted according to the lighting mode, thereby adjusting the color of the emitted second beam. The headlight module disclosed in this application can achieve monochromatic white light emission as well as monochromatic yellow light emission, enabling fog light illumination in environments such as heavy fog. The overall solution has low complexity but strong functionality, achieving monochromatic light emission while meeting the brightness requirements for general lighting and fog lights.

[0023] In conjunction with the first aspect, in some implementations of the first aspect, the first region includes a red region, a green region, and a blue region.

[0024] Based on the above scheme, the color wheel module is configured with red (R), green (G), and blue (B) regions according to the three primary colors of light. Building upon RGB display, color display is achieved by utilizing the persistence of vision in the human eye.

[0025] It should be understood that in some specific implementations, the first region may include a white region in addition to the RGB three primary colors, which can be used to improve the brightness of the color projected image.

[0026] Furthermore, the white area included in the first region can be part or all of the white area included in the second region, or it can be a white area added separately to the first region. This application does not impose any special limitations on this.

[0027] It should be understood that in some specific implementations, the first region may include one or more red regions, one or more green regions, and one or more blue regions. By setting one or more primary color regions, the rainbow effect of the emitted beam can be reduced.

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the second region includes a white region.

[0029] Based on the above solution, setting a white area on the color wheel module can achieve higher brightness white light output. Compared to white light emitted by superimposing the three primary colors of RGB, white light emitted directly through the white area has higher brightness, which can be adapted to high-brightness lighting scenarios and meet the requirements of high-brightness beam emission.

[0030] It should be understood that when a vehicle headlight module needs to achieve monochrome projection, it can achieve projection through a white light area, which can achieve a high-brightness projection effect.

[0031] It should be understood that white light areas can also be used for color projection. When the headlight module is used for color projection display, adding a white area in the color wheel module in addition to the three primary colors of light can increase the overall brightness of the color projection and improve the image display effect.

[0032] In conjunction with the first aspect, in some implementations of the first aspect, the second region includes a white region and a yellow region.

[0033] Based on the above solution, in addition to RGB, a white area and a light color area are added to the color wheel module to meet the needs of different lighting scenarios. The yellow beam emitted from the yellow area will have a higher brightness than the yellow beam emitted through RGB modulation. When used as a fog light, the higher brightness yellow beam can improve driving safety and meet lighting requirements.

[0034] In conjunction with the first aspect, in some implementations of the first aspect, the white area includes a hollowed-out area or a colorless transparent glass area.

[0035] Based on the above solution, the white area achieves white light emission through a hollowed-out area or a colorless transparent glass area. This reduces light loss in the emitted beam and ensures high brightness.

[0036] In conjunction with the first aspect, in some implementations of the first aspect, the first application scenario includes a projection scenario, and the second application scenario includes a lighting scenario.

[0037] Based on the above solution, the vehicle headlight module can be used for both projection and lighting scenarios, enhancing the interactivity between the module and the user. While retaining the high-brightness illumination of the headlight module, it adds more display functions, improving the user experience and meeting the needs of users in multiple scenarios.

[0038] In conjunction with the first aspect, in some implementations of the first aspect, the light source module includes a microLED, which is used to emit a first light beam.

[0039] Based on the above solution, the light source of the vehicle headlight module adopts microLED, which has higher color purity and lower power consumption compared with other light sources.

[0040] Furthermore, the technical solution disclosed in this application can achieve color display by using a microLED as a light source, which reduces the complexity and cost of the light source module.

[0041] Furthermore, this application achieves color display of microLEDs through a color wheel module, eliminating the need for coating the microLED surface with other materials to achieve color output and removing concerns about the uniformity of the coating medium. Moreover, the color display achieved through the color wheel module results in a more uniform emitted color beam, a larger emitting surface, and higher beam brightness. The overall light source module and color wheel module exhibit low structural complexity, high reliability, and high light output stability.

[0042] Furthermore, this application achieves high brightness in the white light beam emitted by the microLED through specific area design on the color wheel module, enabling high-brightness white light emission. While meeting the needs of multimedia and other scenarios, it ensures the brightness of the light emitted by the headlight module, fulfilling high-brightness lighting requirements and guaranteeing vehicle driving safety.

[0043] Secondly, a method for controlling vehicle lights is provided. This method is applied to a vehicle light module, which includes a light source module and a color wheel module. The method includes, in response to a first application scenario of the vehicle light module, causing a first light beam emitted from the light source module to exit through a first region of the color wheel module. In response to a second application scenario of the vehicle light module, causing the first light beam emitted from the light source module to exit through a second region of the color wheel module.

[0044] In conjunction with the second aspect, in some implementations of the second aspect, in response to a first application scenario of the vehicle headlight module, the method further includes acquiring image information, rotating the color wheel module at a first frequency based on the image information, and causing the light source module to emit a first beam at a first moment. The color information superimposed on the first region into which the first beam is incident is the color information included in the image information.

[0045] In conjunction with the second aspect, in some implementations of the second aspect, in response to the vehicle headlight module switching to a first application scenario or a second application scenario, the method further includes driving the color wheel module to translate or rotate along a first direction, so that the incident position of the first beam switches to a first region or a second region.

[0046] In conjunction with the second aspect, in some implementations of the second aspect, in response to the headlight module being in a second application scenario, the method further includes acquiring the lighting mode of the headlight module and controlling the color wheel module to stop at a first position or a second position based on the lighting mode.

[0047] In conjunction with the second aspect, in some implementations of the second aspect, when the color wheel module stops at the first position, the first beam passes through the white area. When the color wheel module stops at the second position, the first beam passes through the yellow area.

[0048] In conjunction with the second aspect, in some implementations of the second aspect, the first region includes a red region, a green region, and a blue region.

[0049] In conjunction with the second aspect, in some implementations of the second aspect, the second region includes a white region.

[0050] In conjunction with the second aspect, in some implementations of the second aspect, the second region includes a white region and a yellow region.

[0051] In conjunction with the second aspect, in some implementations of the second aspect, the white area includes a hollowed-out area or a colorless transparent glass area.

[0052] In conjunction with the second aspect, in some implementations of the second aspect, the first application scenario includes a projection scenario, and the second application scenario includes a lighting scenario.

[0053] In conjunction with the second aspect, in some implementations of the second aspect, the light source module includes a microLED, which is used to emit a first light beam.

[0054] Thirdly, embodiments of this application provide a vehicle lighting system, including a control system and a vehicle lighting module provided in the first aspect and any implementation thereof. The control system is used to acquire the application scenario of the vehicle lighting module and control the area where a first light beam is incident on the color wheel module according to the application scenario.

[0055] It is understandable that the application scenarios of automotive lighting modules include the first and second application scenarios mentioned above. The control system can be a control device, controller, control module, control apparatus, etc. In some feasible implementations, the control system can be a central control system, and also has other control functions, including but not limited to acquiring the application scenario of the automotive lighting module and controlling the on or off of multiple light sources according to the application scenario.

[0058] In one implementation, the device is a control device.

[0081] The following description is provided to facilitate understanding of the embodiments of this application.

[0082] First, the terms "first," "second," and various numerical designations used in the textual descriptions or drawings of the embodiments of this application shown below are merely for descriptive convenience and are not intended to limit the scope of the embodiments of this application. For example, the first beam and the second beam are different beams, etc.

[0083] Second, the term "comprising" and any variations thereof in the embodiments of this application shown below are intended to cover non-exclusive inclusion, for example, a system, product or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.

[0084] Third, in the embodiments of this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Embodiments or designs described as "exemplarily" or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. The use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner to facilitate understanding.

[0085] Fourth, in the embodiments of this application, image light refers to light carrying an image (or image information) used to generate an image, and can also be called imaging light, etc.

[0086] Fifth, in the accompanying drawings of this application, the thickness, size, and shape of the various optical elements have been slightly exaggerated for ease of illustration. Specifically, the shapes of the optical elements shown in the drawings are illustrated by way of example, and the drawings are for illustrative purposes only and are not drawn strictly to scale.

[0087] Sixth, unless otherwise specified, all terms used in this application (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0088] Intelligentization has become a major development direction in the current automotive industry, and the headlight module, as the "eyes" of the vehicle, is gradually playing a more important role in intelligent vehicles to provide a safer, smarter, and more efficient driving experience. With continuous technological advancements, intelligent headlight modules are now not only responsible for illumination but also for projection, providing users with new entertainment experiences. To further enhance the effect of projected images, headlight modules can also achieve color projection.

[0089] There are many choices of light source modules commonly used in automotive lighting modules, including lighting systems that use light-emitting diode (LED) matrices, lighting systems that use digital light processing (DLP) technology, and lighting systems that use micro light-emitting diodes (microLEDs), etc.

[0090] Compared to LED matrix lighting systems, microLED lighting systems offer pixel-level precision control, resulting in more refined lighting and display effects. Furthermore, microLED lighting systems boast higher brightness, providing clearer and brighter visibility at night or in adverse weather conditions, thus improving driving safety. Moreover, the miniaturized design of microLEDs allows for easier creation of display panels of various shapes and sizes, meeting the diverse needs of automotive design.

[0091] Compared to automotive lighting systems using DLP technology, automotive lighting systems using microLED technology can further reduce energy consumption and require less design complexity while maintaining high performance and projection interaction functions.

[0092] Figure 1 shows a microLED light source module.

[0093] The light source module shown in the figure generates colored beams by exciting a specific medium with blue light. Specifically, different light-emitting media are coated within each individual pixel of the microLED's active area (AA) to achieve the emission of three colors—red (R), green (G), and blue (B)—within a single pixel, ultimately realizing a color display.

[0094] As an example and not a limitation, the luminescent medium can be phosphor or quantum dot, etc.

[0095] However, it is difficult to guarantee the uniformity of coating in this scheme, which will affect the uniformity of the emitted beam. Furthermore, the small actual light-emitting surface will also lead to low brightness of the emitted beam and lower overall reliability of the light source module.

[0096] Figure 2 shows another type of microLED light source module.

[0097] The light source module shown in the diagram achieves color display by using three colors of light and employing a spatial light beam combining scheme. Specifically, color display is achieved through three microLED chips of different colors: microLED chip 1, microLED chip 2, and microLED chip 3. A special light combining element is then used to combine the wavelengths of the light, and the combined beam is emitted through a projection lens module.

[0098] However, this solution has high light source costs, and the special packaging method leads to low spectral efficiency and low module brightness. Furthermore, the three-piece structure requires high alignment precision, and the overall optical structure is complex, which increases the complexity of the light source module, making mass production difficult and subsequent maintenance challenging.

[0099] Figure 3 shows another type of microLED light source module.

[0100] The light source module shown in the figure achieves color display by stacking full-color micro-display chips vertically on the light-emitting side (AA area). Specifically, three self-emissive layers are stacked vertically on the microLED chips: aluminum indium gallium phosphide (ALInGaP) for emitting red light, and indium gallium nitride (InGaN) for emitting green and blue light. Through chip-level alignment, the three emissive layers are aligned, ultimately achieving color display.

[0101] However, this solution has low reliability and the emitted white light has low brightness, which cannot meet the brightness requirements of the lighting scene.

[0102] It should be understood that the emission of different colors of light described in this application can also be understood as the emission of light of different wavelengths, and this application does not make any special limitation in this regard.

[0103] In view of this, this application proposes a vehicle headlight module that enables color projection display while ensuring the emitted brightness when used for lighting functions. Furthermore, the technical solution of this application has high reliability, low process difficulty requirements, is easy to mass-produce, and has low production costs.

[0104] The following section first describes the vehicles to which the headlight module provided in this application can be applied.

[0105] Figure 4 is a functional block diagram of one embodiment of the vehicle provided in this application.

[0106] In one embodiment, vehicle 100 is configured in a fully or partially autonomous driving mode. For example, vehicle 100 can control itself while in autonomous driving mode, and can determine the current state of the vehicle and its surrounding environment through human intervention, determine the possible behaviors of at least one other vehicle in the surrounding environment, and determine the confidence level corresponding to the probability of that other vehicle performing the possible behavior, and control vehicle 100 based on the determined information. When vehicle 100 is in autonomous driving mode, vehicle 100 can be configured to operate without human interaction. Vehicle 100 may include various systems, each system may include multiple components. Furthermore, each system and component of vehicle 100 may be interconnected via wired or wireless means.

[0107] The vehicle shown in this embodiment includes a sensor system 120, which may include several sensors for sensing information about the environment surrounding the vehicle 100. For example, the sensor system 120 may include a positioning system 121 (which may be a Global Positioning System (GPS), BeiDou Navigation Satellite System, or other positioning systems), an inertial measurement unit (IMU) 122, a radar 123, a laser rangefinder 124, and a camera 125. The sensor system 120 may also include sensors for the internal systems of the monitored vehicle 100 (e.g., an in-vehicle air quality monitor, fuel gauge, oil temperature gauge, etc.). Sensor data from one or more of these sensors can be used to detect objects and their corresponding characteristics (position, shape, orientation, speed, etc.). This detection and identification is a key function for the safe operation of the autonomous vehicle 100. The positioning system 121 can be used to estimate the geographical location of the vehicle 100. The IMU 122 is used to sense changes in the position and orientation of the vehicle 100 based on inertial acceleration. In one embodiment, the IMU 122 may be a combination of an accelerometer and a gyroscope. Radar 123 can use radio signals to sense objects in the surrounding environment of vehicle 100. In some embodiments, in addition to sensing objects, radar 123 can also be used to sense the speed and / or direction of travel of objects. This embodiment does not limit the specific type of radar 123; for example, radar 123 can be millimeter-wave radar or lidar, etc. Laser rangefinder 124 can use lasers to sense objects in the environment in which vehicle 100 is located. In some embodiments, laser rangefinder 124 may include one or more laser sources, laser scanners, and one or more detectors, as well as other system components. Camera 125 can be used to capture multiple images of the surrounding environment of vehicle 100. Camera 125 can be a still camera, video camera, monocular / binocular camera, or infrared imager.

[0108] Vehicle 100 also includes an advanced driving assistance system (ADAS) 110. ADAS 110 continuously senses the surrounding environment during vehicle operation, collects data, identifies, detects, and tracks static and dynamic objects, and combines this data with navigation map data to perform system calculations and analyses. This allows the driver to anticipate potential dangers, effectively increasing driving comfort and safety. For example, ADAS 110 can control the vehicle using data acquired by the sensor system 120. Alternatively, ADAS 110 can control the vehicle using in-vehicle infotainment system data, which may include key data from the vehicle's instrument panel (fuel consumption, engine speed, temperature, etc.), vehicle speed information, steering wheel angle information, or vehicle attitude data.

[0109] ADAS 110 controls the vehicle in one or more of the following ways: ADAS 110 adjusts the forward direction of vehicle 100. ADAS 110 controls the operating speed of the vehicle's engine and thus the speed of vehicle 100. ADAS 110 operates on images captured by camera 125 to identify objects and / or features in the environment surrounding vehicle 100. In some embodiments, ADAS 110 may be used to map the environment, track objects, estimate the speed of objects, etc. ADAS 110 determines the driving route of vehicle 100; in some embodiments, ADAS 110 may combine one or more predetermined map data from sensor system 120 to determine the driving route for vehicle 100. ADAS 110 may identify, assess, and avoid or otherwise traverse potential obstacles in the environment of vehicle 100.

[0110] Vehicle 100 interacts with external sensors, other vehicles, other computer systems, or users via peripheral devices 130. Peripheral devices 130 may include a wireless communication system 131, an on-board computer 132, a microphone 133, and / or a speaker 134.

[0111] In some embodiments, peripheral device 130 provides a means for a user of vehicle 100 to interact with a user interface. For example, on-board computer 132 may provide information to a user of vehicle 100. The user interface may also operate on-board computer 132 to receive user input. On-board computer 132 may be operated via a touchscreen. In other cases, peripheral device 130 may provide a means for vehicle 100 to communicate with other devices located within the vehicle. For example, microphone 133 may receive audio (e.g., voice commands or other audio input) from a user of vehicle 100. Similarly, speaker 134 may output audio to a user of vehicle 100.

[0112] The wireless communication system 131 can communicate wirelessly with one or more devices directly or via a communication network. For example, the wireless communication system 131 can use third-generation (3G) cellular communication technologies, such as Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), or General Packet Radio Service (GPRS). The wireless communication system 131 can use fourth-generation (4G) cellular communication technologies, such as Long Term Evolution (LTE). The wireless communication system 131 can also use fifth-generation (5G) cellular communication technologies. The wireless communication system 131 can communicate using a wireless local area network (WLAN). In some embodiments, the wireless communication system 131 can communicate directly with devices using an infrared link, Bluetooth, or ZigBee. The wireless communication system 131 may also utilize various vehicle communication systems. For example, the wireless communication system 131 may include one or more dedicated short range communications (DSRC) devices, which may include public and / or private data communications between vehicles and / or roadside stations.

[0113] Some or all of the functions of vehicle 100 are controlled by computer system 140. Computer system 140 can control the functions of vehicle 100 based on input received from various systems (e.g., sensor system 120, ADAS 110, peripheral devices 130) and from a user interface. Computer system 140 may include at least one processor 141 that executes instructions stored in a non-transitory computer-readable medium such as memory 142. Computer system 140 may also be multiple computing devices controlling individual components or subsystems of vehicle 100 in a distributed manner.

For example, the processor 141 may be one or more field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), system-on-chips (SoCs), central processing units (CPUs), network processors (NPs), digital signal processors (DSPs), microcontroller units (MCUs), programmable logic devices (PLDs), or other integrated chips, or any combination of the above chips or processors.

[0115] In some embodiments, memory 142 may contain instructions (e.g., program logic) that can be executed by processor 141 to perform various functions of vehicle 100. In addition to instructions, memory 142 may also store data such as map data, route information, vehicle position, direction, speed, and other vehicle data. The information stored in memory 142 can be used by vehicle 100 and computer system 140 during operation of vehicle 100 in autonomous, semi-autonomous, and / or manual modes.

[0116] The vehicle 100 shown in this embodiment also includes a headlight module 150, which is capable of realizing an intelligent headlight system that combines high-brightness illumination and high-definition projection. The specific structure of the headlight module 150 is described below with reference to various embodiments. The lighting module shown in this embodiment can be applied not only to vehicles but also to other driving vehicles such as ships, airplanes, and helicopters.

[0117] It is understood that the schematic structural block diagram of vehicle 100 shown in the figure is only a structure of a vehicle applicable to the embodiments of this application, but this application is not limited to this. The systems or devices included in the vehicle to which this application applies may also include others, such as head-up display (HUD) devices, in-vehicle virtual image display devices, automatic emergency braking (AEB) systems, etc.

[0118] Figure 5 is a structural schematic diagram of the vehicle headlight module 150 provided in an embodiment of this application.

[0119] The headlight module 150 includes a light source module 101, a color wheel module 102, and a lens module 103. The color wheel module 102 is located on the light-emitting side of the light source module 101. The light source module 101 emits a light beam carrying image information. The color wheel module 102 rotates according to the colors included in the image information, causing the light beam emitted by the light source module 101 to be superimposed with the image information to generate image light. The lens module 103 emits the image light.

[0120] The first light beam emitted from the light source module 101 is incident on the color wheel module 102. The color wheel module 102 rotates according to the image information, modulates the first light beam, and emits a second light beam. The first light beam is used to carry image information, and the second light beam is the light beam carrying image information.

[0121] It should be understood that image light includes light beams carrying image information, also known as image beams, and this application does not specifically limit this.

[0122] It should be understood that the image light is a specific implementation of the second beam, and this application does not impose any special limitations on it.

[0123] In one specific implementation, the light source module 101 includes a microLED chip, which is not specifically limited in this application.

[0124] Utilizing the persistence of vision effect of the human eye, the color wheel module 102 is divided into red (R), green (G), and blue (B) regions according to the three primary colors of light, and a color image is displayed through timing. Based on the image information, the color wheel module 102 is driven to rotate, modulating the first light beam so that the second light beam exiting the color wheel module 102 carries the image information, thereby realizing the color display of the vehicle headlight module 150.

[0125] In some specific implementations, the control module 160 outputs drive signal 1 and drive signal 2 based on the image information. Drive signal 1 is used to drive the color wheel module 102 to rotate, causing the first light beam to exit through region 1 at the first moment; drive signal 2 is used to drive the light source module 101 to emit the first light beam at the first moment. The color corresponding to region 1 is the color included in the image information at the first moment.

[0126] In some specific implementations, the drive signal 1 output by the control module 160 is used to drive the color wheel module 102 to rotate at a first frequency, and the drive signal 2 is used to drive the light source module 101 to emit a first light beam at a first moment and stop emitting the first light beam at a second moment. Specifically, at the first moment, the light beam emitted by the light source module 101 exits through region 1 of the color wheel module 102, and at the second moment, the light beam emitted by the light source module 101 exits through region 2 of the color wheel module 102. The color corresponding to region 1 is the color included in the image information at the first moment. The color corresponding to region 2 is the color not included in the image information at the second moment.

[0127] It should be understood that Region 1 and / or Region 2 are specific implementations of one or more regions included in the first region in the implementation of this application, and this application does not make any special limitations on them.

[0128] It should be noted that the control module 160 can be located inside or outside the headlight module 150, and this application does not impose any special limitations on this.

[0129] As an example and not a limitation, the color display of the headlight module 150 is described below with reference to a color wheel module 102 shown in Figure 6.

[0130] Figure 6 is a structural schematic diagram of a color wheel module provided in an embodiment of this application.

[0131] By way of example and not limitation, Figure 6 illustrates the color composition of a color wheel module 102. The color wheel module 102 includes a color wheel panel 1021 and a drive shaft 1022. The color wheel panel 1021 is used to modulate the color of the emitted light beam, and the drive shaft 1022 is used to drive the color wheel panel 1021 to rotate.

[0132] As an example and not a limitation, the color wheel panel 1021 is divided into a white (W) light area and a color display area according to the application scenario of the headlight module 150. The color display area is divided into red (R), green (G), and blue (B) areas according to the three primary colors of light.

[0133] When the color wheel module 102 rotates and the incident position of the first beam is in region R, the emitted second beam superimposed with red image information, and the beam emitted by the lens module 103 projects a red graphic. When the color wheel module 102 rotates and the incident position of the first beam is in region G, the emitted second beam superimposed with green image information, and the beam emitted by the lens module 103 projects a green graphic. When the color wheel module 102 rotates and the incident position of the first beam is in region B, the emitted second beam superimposed with blue image information, and the beam emitted by the lens module 103 projects a blue graphic. When the color wheel module 102 rotates and the incident position of the first beam is in region G, the emitted second beam superimposed with green image information, and the beam emitted by the lens module 103 projects a green graphic.

[0134] When the headlight module 150 is in the first application scenario, the color wheel module 102 rotates so that the incident position of the first beam is in the color display area, and the second beam superimposed with image information to achieve color display. When the headlight module is in the second application scenario, the color wheel module 102 rotates to position 1 and is fixed, so that the incident position of the first beam is in the white light area, and the emitted second beam is white light.

[0135] In one specific implementation, the white light area is a hollowed-out area. When the color wheel module 102 rotates, causing the first beam to be incident on the white (W) area, the entire first beam passes through the color wheel module 102 and exits through the lens module 103, thus achieving white light illumination.

[0136] In another specific implementation, the white light area is colorless transparent glass or transparent colorless augmented reality (AR) glass. When the color wheel module 102 rotates, causing the first beam to be incident on the white (W) area, the entire first beam passes through the color wheel module 102 and exits through the lens module 103, thus achieving white light illumination.

[0137] It should be understood that the white light area is a specific implementation of the second area in the implementation of this application, and the color display area is a specific implementation of the first area in the above-mentioned implementation of this application. This application does not make any special limitations on this.

[0138] It should be understood that this application does not impose any special limitation on the type of filter in the color wheel, including but not limited to transparent glass, colored glass, etc., and may also be a filter of other materials. This application does not impose any special limitation on this.

[0139] It should be understood that in some specific implementations, the white light area of ​​the color wheel module 102 is also referred to as the white (W) area on the color wheel panel 1021; the color display area of ​​the color wheel module 102 is also referred to as the color display area of ​​the color wheel panel 1021, and this application does not make any special limitation on this.

[0140] It should be understood that in some specific implementations, the white light area is also referred to as the white area; the color display area is also referred to as the display area, projection area, color area, etc., and this application does not make any special limitation on this.

[0141] As an example and not a limitation, the rotation frequency of the color wheel module 102 is greater than or equal to 60 Hz.

[0142] It should be understood that the arrangement of R, G, B, and W in the color wheel module 102 shown in the figure is only an example and does not limit the color sorting of the color wheel module 102. The color wheel module 102 may also have other color sortings, such as R, B, G, W or G, R, W, B, etc., and this application does not make any special limitations on this.

[0143] It should be understood that the proportions of the color display area and the white light area of ​​the color wheel module 102 can be the same or different, and this application does not impose any special limitations on this.

[0144] It should be understood that the color display area may include a white (W) area in addition to the three primary colors RGB, which can further improve the brightness of the color projected image. This application does not make any special limitation in this regard.

[0145] It should be understood that in the color wheel module 102, the proportions of any two of the four color regions R, G, B, and W are not necessarily the same, and this application does not impose any special restrictions on this.

[0146] As an example and not a limitation, the proportions of the three colors R, G, and B in the color display area of ​​the color wheel module 102 are the same as the proportions of the three colors in white light.

[0147] Furthermore, it should be understood that in the color display area of ​​the color wheel module 102, each color proportion color area may include one or more areas.

[0148] As an example and not a limitation, the color display area includes two red areas, two blue areas, and two green areas, while the white area includes one cutout area or transparent colorless AR glass.

[0149] As an example rather than a limitation, the color display area includes 3 red areas, 2 blue areas and 1 green area, and the white area includes 2 cutout areas or transparent colorless AR glass.

[0150] It should be understood that the number of regions mentioned above is merely illustrative and this application does not impose any special limitations on it.

[0151] By way of example and not limitation, the color wheel panel 1021 includes colored glass, and the optical glass is coated with a film according to the proportion of different color areas. This application does not make any special limitation in this regard, nor should it be considered that other structures of the color wheel panel 1021 are beyond the protection scope of this application.

[0152] It should be understood that the area of ​​the color wheel module 102 for emitting the second beam includes a circle, and can also be annular, square, etc., and this application does not make any special limitation in this regard.

[0153] In another specific implementation, the headlight module 150 also includes a light source module 104 (not shown in the figure). Light source module 101 is the light source module for a first application scenario, and light source module 104 is the light source module for a second application scenario. When the headlight module 150 is in the first application scenario, light source module 101 emits a first light beam, and color wheel module 102 rotates, causing a second light beam to superimpose image information to achieve color display. When the headlight module is in the second application scenario, light source module 104 emits a first light beam, color wheel module 102 is fixed, and the first light beam passes through a white light region, resulting in a white light emitted as the second light beam.

[0154] Based on the above technical solution, the color wheel module is divided into display areas of different colors. By driving the color wheel module to rotate, the light beam emitted by the light source module is modulated, so that the light beam emitted by the color wheel module has different colors, thereby realizing the color display of the vehicle headlight module. Furthermore, a special area for emitting white light is set on the color wheel, which can enable the vehicle headlight module to emit high brightness when performing functions such as illumination. The technical solution disclosed in this application has high light extraction efficiency, high brightness, and high color uniformity of the emitted light beam. Moreover, the overall solution has low structural complexity, high system reliability, is suitable for mass production, and has cost advantages.

[0155] Figure 7 is a schematic diagram of another color wheel module provided in an embodiment of this application.

[0156] By way of example and not limitation, Figure 7 shows another color composition of color wheel module 102. Color wheel module 102 includes color wheel panel 1021 for modulating the color of the emitted light beam and drive shaft 1022 for driving color wheel panel 1021 to rotate.

[0157] As an example and not a limitation, the color wheel panel 1021 is divided into an illumination display area and a color display area according to the application scenario of the headlight module 150. The illumination display area includes a white (W) light area and a yellow (Y) light display area. The color display area is divided into red (R), green (G), and blue (B) areas according to the three primary colors of light.

[0158] It should be understood that the lighting display area is a specific implementation of the second area in the implementation of this application, and the color display area is a specific implementation of the first area in the above-mentioned implementation of this application. This application does not make any special limitations on this.

[0159] When the color wheel module 102 rotates to the Y region, the emitted second beam superimposed with yellow image information, and the beam emitted by the lens module 103 projects and displays a yellow graphic.

[0160] In one specific implementation, when the headlight module 150 is in the second application scenario and fog light illumination is required, the color wheel module is fixed so that the first beam enters the yellow light area and the emitted second beam is yellow light. In this case, the headlight module 150 is suitable for the fog light application scenario.

[0161] It should be understood that when the headlight module 150 is in a fog light illumination scenario, the first beam can be emitted by the light source module 101 or by the light source module 104, and this application does not make any special limitation on this.

[0162] It should be understood that this application does not impose any special limitations on the area ratio of white light and yellow light areas in the lighting display area, nor does it impose any special limitations on the area ratio of the lighting display area and the color display area.

[0163] Based on the above technical solution, the color wheel module is divided into display areas of different colors. By driving the color wheel module to rotate, the light beam emitted by the light source module is modulated, so that the light beam emitted by the color wheel module has different colors, thereby realizing the color display of the vehicle headlight module. Furthermore, a specific area is set on the color wheel for emitting white light, which enables the vehicle headlight module to emit high brightness when performing functions such as lighting. A yellow light area can also be set on the color wheel for emitting yellow light, enabling the vehicle headlight module to function as a fog light. The technical solution disclosed in this application has high light extraction efficiency, high brightness, and high color uniformity of the emitted beam. Moreover, the overall solution can adapt to various scenarios such as fog light lighting, white light lighting, and color projection. The solution of this application has low structural complexity, high system reliability, is suitable for mass production, and has cost advantages.

[0164] Figure 8 is a structural schematic diagram of another color wheel module provided in an embodiment of this application.

[0165] By way of example and not limitation, Figure 8 illustrates another color composition of color wheel module 102. Color wheel module 102 includes color wheel panel 1021 and drive shaft 1022. Color wheel panel 1021 is used to modulate the color of the emitted light beam, and drive shaft 1022 is used to drive color wheel panel 1021 to rotate. Drive shaft 1022 can also be used to drive color wheel panel 1021 to translate along a first direction.

[0166] By way of example and not limitation, the color wheel panel 1021 is divided into an illumination display area and a color display area according to the application scenario of the headlight module 150. The color wheel panel 1021 includes at least one annular area, which is the illumination display area. The area within the annular area is the color display area.

[0167] As an example, and not a limitation, the lighting display area includes white (W) light areas and yellow (Y) light display areas. The color display area is divided into red (R), green (G), and blue (B) areas according to the three primary colors of light.

[0168] In one specific implementation, when the headlight module 150 is in the first application scenario, the drive shaft 1022 drives the color wheel panel 1021 to rotate, the incident position of the first beam is in the color display area, and the first beam is modulated according to the image information, so that the second beam superimposed on the image information achieves color display.

[0169] In another specific implementation, when the vehicle light module 150 is in the second application scenario, the drive shaft 1022 drives the color wheel panel 1021 to translate along the first direction, so that the first beam emitted from the lens module 103 enters the illumination display area, and the emitted second beam is used for illumination.

[0170] By way of example and not limitation, the first direction includes both horizontal and vertical directions, and this application does not make any special limitation in this regard.

[0171] In one specific implementation, when the color wheel panel 1021 is in the initial position, the first beam emitted by the light source module 101 is incident on the color display area; the drive shaft 1022 drives the color wheel panel 1021 to translate from the initial position along the first direction, so that the incident position of the first beam is the illumination display area.

[0172] In another specific implementation, when the color wheel panel 1021 is in the initial position, the first beam emitted by the light source module 101 is incident at the illumination display area; the drive shaft 1022 drives the color wheel panel 1021 to translate from the initial position along the first direction, so that the incident position of the first beam is the color display area.

[0173] As an example and not a limitation, Figure 8(a) shows the composition of a color wheel panel 1021. The central area of ​​the color wheel panel 1021 is a color display area, divided into red (R), green (G), and blue (B) areas according to the three primary colors of light. The annular area outside the central area is a lighting display area, divided into white (W) and yellow (Y) areas according to the vehicle driving scene.

[0174] In one specific implementation, when the headlight module is in the second application scenario, the first light beam is incident on the lighting display area. If the second light beam emitted at the current moment is white light, it needs to switch to fog light mode, that is, the second light beam needs to be modulated to yellow light. At this time, the drive shaft 1022 drives the color wheel panel 1021 to rotate from its current position, so that the incident position of the first light beam is in the yellow (Y) area. Similarly, if the second light beam emitted at the current moment is yellow light and needs to be switched to white light, the drive shaft 1022 drives the color wheel panel 1021 to rotate from its current position, so that the incident position of the first light beam is in the yellow (W) area.

[0175] As an example and not a limitation, Figure 8(b) illustrates the composition of a color wheel panel 1021. The central area of ​​the color wheel panel 1021 is a color display area, divided into red (R), green (G), and blue (B) areas according to the three primary colors of light. The annular area outside the central area is an illumination display area. The annular area includes two rings, one of which is divided into a white (W) area and the other into a yellow (Y) area according to the vehicle driving scenario.

[0176] In one specific implementation, when the headlight module is in the second application scenario, the first light beam is incident on the lighting display area. If the second light beam emitted at the current moment is white light, it needs to switch to fog light mode, that is, the second light beam needs to be modulated to yellow light. At this time, the drive shaft 1022 drives the color wheel panel 1021 to translate along the first direction based on the current position of the color wheel panel 1021, so that the incident position of the first light beam is the yellow (Y) area. Similarly, if the second light beam emitted at the current moment is yellow light and it needs to be switched to white light, the drive shaft 1022 drives the color wheel panel 1021 to translate in the opposite direction of the first direction based on the current position of the color wheel panel 1021, so that the incident position of the first light beam is the yellow (W) area.

[0177] It should be understood that when two annular regions are included, one annular region is the yellow (Y) region and the other annular region is the white (W) region, and no special restrictions are made on the inner and outer rings of the two colors.

[0178] It should be understood that this application does not impose any special limitation on the area ratio of red (R), green (G) and blue (B) regions in the color display area. The accompanying drawings are only schematic drawings and do not constitute any limitation on the scope of protection of this application, nor should they be considered as other implementation methods of area ratio exceeding the scope of protection of this application.

[0179] It should be understood that this application does not impose any special limitation on the area ratio of white (W) and yellow (Y) regions in the lighting display area. The accompanying drawings are only schematic drawings and do not constitute any limitation on the scope of protection of this application, nor should they be considered as other ways of implementing the area ratio exceeding the scope of protection of this application.

[0180] It should be understood that this application does not impose any special limitation on the area ratio of the lighting display area (ring area) and the color display area (central area). The accompanying drawings are only schematic drawings and do not constitute any limitation on the scope of protection of this application, nor should they be considered as other ways of realizing the area ratio exceeding the scope of protection of this application.

[0181] Based on the above technical solution, the central area of ​​the color wheel is divided into three regions based solely on the three primary colors of light. Compared to dividing it into multiple regions, with a fixed rotation speed of the color wheel panel, the light beam emitted by the light source module stays in the color display area for a longer time, which can further improve the brightness of the color display area and further enhance the image quality of the color display. Furthermore, the solution in this application also covers the functions of white light illumination and fog light illumination.

[0182] It should be understood that in the implementation of this application, the drive shaft 1022 is used to drive the color wheel panel 1021 to rotate, which can be clockwise or counterclockwise, and this application does not make any special limitation on this.

[0183] It should be noted that in this application, the first application scenario of the headlight module 150 is a projection scenario, and the second application scenario is a lighting scenario or lighting mode. The projection scenario is merely an exemplary name. In a projection scenario, the headlight module 150 can achieve color projection of an image or generate a color image, no longer simply emitting white light for illumination; that is, the headlight module 150 is used for functions other than illumination. It is understood that the projection scenario can also be called an imaging scenario, an entertainment scenario, a high-definition demand scenario, etc. Similarly, the lighting scenario is merely an exemplary name. In a lighting scenario, the headlight module 150 is used to emit a single-color beam of light, including but not limited to using a single-color beam of light for illumination, or for achieving monochrome projection, or for generating a single-color image. It is understood that the lighting scenario can also be called a high-brightness demand scenario, an illumination scenario, etc., for example, the headlight module could be operating in scenarios such as adaptive high beam (ADB), light carpet, fog lights, etc.

[0184] Figure 9 is a schematic diagram of the position of the light source module provided in the embodiment of this application.

[0185] By way of example and not limitation, Figure 9 shows a schematic diagram of the relative positions of the light source module 101 and the color wheel module 102. The light source module 101 emits a first light beam, and the incident position of the first light beam on the color wheel module 102 is located within the color wheel panel 1021.

[0186] The light source module 101 can be arranged horizontally as shown in Figure 9(a); the light source module 101 can also be arranged vertically as shown in Figure 9(b), and this application does not make any special limitation in this regard.

[0187] By way of example and not limitation, the light source module 101 includes, but is not limited to, microLED chips.

[0188] It should be understood that the distribution of the color display area and the illumination display area on the color wheel panel 1021 may include, but is not limited to, any of the possible implementations shown in Figures 6 to 8, and this application does not impose any special limitations on this.

[0189] It should be understood that the initial position of the first beam emitted from the light source module 101 incident on the color wheel panel 1021 can be in the color display area or the lighting display area, and this application does not make any special limitation on this.

[0190] Furthermore, when the application scenario of the headlight module 150 changes, the color wheel module 102 rotates and / or translates under the action of the drive shaft 1022, thereby changing the incident area of ​​the first beam incident on the color wheel panel 1021.

[0191] Figure 10 is a schematic flowchart of a method 100 for controlling vehicle lights provided in an embodiment of this application.

[0192] Method 100 can be executed by a control device, specifically by a control module 160 included in the headlight module 150, or by a vehicle's central control system, central control device, or processing chip connected to the headlight module 150. Specifically, method 100 includes the following steps.

[0193] S102, in response to the first application scenario of the vehicle lighting module, causes the first beam emitted by the light source module to be emitted through the first area of ​​the color wheel module; or, in response to the second application scenario of the vehicle lighting module, causes the first beam emitted by the light source module to be emitted through the second area of ​​the color wheel module.

[0194] Specifically, in response to the first application scenario of the vehicle lighting module, the control device acquires image information and, based on the image information, causes the color wheel module to rotate at a first frequency. The control device is also used to cause the light source module to emit a first beam of light at the first moment.

[0195] Specifically, in response to the second application scenario of the headlight module, the control device acquires the lighting mode of the headlight module and controls the color wheel module to stop at the first or second position according to the lighting mode.

[0196] Optionally, before S102, the method further includes the following S101.

[0197] S101, Obtain the application scenario of the vehicle lighting module, which includes the first application scenario and the second application scenario.

[0198] In some possible ways, the processing device acquires the application scenario of the headlight module by receiving instructions from the user. For example, when the user needs to use the headlight module for color projection imaging, the user selects the headlight module's application scenario as the first application scenario on the interactive interface. This causes the control device to acquire the image data to be projected according to the user's instructions and send drive signal 1 to drive the color wheel panel 1021 to rotate at a first frequency. The control device is also used to send drive signal 2 according to the image data, driving the light source module 101 to emit a first light beam or pause light emission according to the color information included in the image information, so that the first light beam incident on the color area of ​​the color wheel panel 1021 is the color included in the image information. When the color area of ​​the color wheel panel 1021 is a color not included in the image information, drive signal 2 is also used to control the light source module 101 to stop emitting light.

[0199] In other possible ways, the application scenario of the headlight module can be automatically adjusted by the processing device through detectors, sensors, etc. For example, when the vehicle is driving in a relatively dark environment, the control device can determine that the headlight module needs to work in a second application scenario based on the brightness sensor on the vehicle. At this time, the drive signal 2 sent by the control device is used to make the light source module 101 emit a first beam, and the drive signal 1 sent by the control device is used to make the color wheel panel 1021 rotate or translate in a first direction, so that the first beam is incident on the illumination area of ​​the color wheel panel 1021, achieving a high-brightness auxiliary lighting effect.
