Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, and in particular to a display interactive vehicle lamp based on mini LED. Background Art

[0002] As the main means of transportation in daily life, cars occupy an important position in people's lives. The existing interaction between vehicles and the environment mainly relies on the basic driving signals of vehicles. Vehicles actively send signals to other vehicles and pedestrians according to their own driving intentions, such as turn signals, brake signals, reversing signals, horns, etc. With the development of the new four modernizations of automobiles, cars can obtain more and more information about the surrounding environment through radar and other systems. Therefore, cars have gradually developed more interactive signals, such as collision reminders and lane departure reminders for drivers.

[0003] With the development of automobile lighting technology, a type of LED-based pixelated headlight is becoming more and more popular. This type of headlight uses ordinary LED particles, and through light guides and exterior trims, it forms a display screen with hundreds of pixels. It can display simple symbols such as arrows, warnings, and simple fun interactions. However, the existing signal interaction between vehicles and the environment is still at a relatively simple sound and light level, and the information transmitted is limited; automobile signal lights intelligently transmit several simple information such as braking and turning at the regulatory level. Honking can only attract the attention of other vehicles and pedestrians through sound, and cannot effectively convey specific information; and in areas where honking is prohibited and noisy, honking cannot play an effective role. In this case, other vehicles and pedestrians cannot accurately obtain the driving intention of the vehicle, resulting in a certain probability of traffic accidents, which is not conducive to improving road safety. LED-based pixelated headlights are limited by the size of LED particles and structural parts. The center spacing of pixels is generally around 8-10mm. Therefore, under a relatively fixed display area, the number of pixels is limited, and the fineness and diversity of the pattern symbols that can be displayed are limited, which cannot meet the signal interaction display requirements of more complex scenes.

[0004] Therefore, it is necessary to design a new type of headlight to solve the problem that the current information interaction between cars and cars, cars and pedestrians is only light signals such as position, steering, braking, reversing, and honking, and the information is vague and single. It also solves the problem that the current LED-based pixelated headlights have a large pixel pitch and cannot display complex and delicate patterns. The interaction method between cars and the environment is difficult to meet the diverse information needs of the future intelligent development of cars. Utility Model Content

[0031] By densely packaging the mini LED chips 101 on the circuit board 102, a display screen with a pixel pitch of less than 1 mm can be realized, which can display various, complex, and delicate patterns, symbols and other road interaction information, allowing pedestrians and other moving vehicles to obtain more road safety information, clarify the driving intention of the vehicle, and improve road safety;

[0032] By using the packaging module formed by the mini LED module 1, the mini LED screen with thousands or tens of thousands of pixels can be regarded as a uniformly luminous and editable surface light source, eliminating the light-guiding plastic parts of conventional LED pixel headlights, greatly reducing the thickness of the light source, and saving the internal space of the headlights;

[0033] By using interactive display lights composed of mini LEDs, the entire vehicle's appearance can be customized with richer and more personalized display patterns, making the vehicle a consumer product with more user characteristics and a better user experience.

[0034] In one embodiment, the mini LED chip 101 is a monochrome chip.

[0035] In one embodiment, the mini LED chip 101 is an RGB chip.

[0036] In one embodiment, the number of the mini LED module 1 is one.

[0037] In one embodiment, the number of the mini LED modules 1 is multiple.

[0038] In this embodiment, the mini LED display interactive car light can be composed of a whole mini LED module or multiple mini LED modules, and the size and shape can be adjusted as needed. The front or rear of the car 2 can display rich interactive information according to the driving conditions.

[0039] The mini LED module 1 is composed of a mini LED chip 101, a circuit board 102, a driver 104, connectors and other electronic components 103. The single size of the mini LED chip 101 is less than 1mm, and it can be an RGB or monochrome chip. The mini LED chip 101 is packaged on the circuit board 102, and the center spacing of the mini LED chip 101 is less than 1mm. The overall thickness of the mini LED module 1 is less than 10mm. The mini LED chip 101 with thousands / millions of pixels and smaller spacing can display a variety of complex interactive patterns and symbols, providing rich and delicate road driving information.

[0040] In one embodiment, the driver 104 is connected to a light controller.

[0041] In one embodiment, the light controller is connected to a vehicle body control module.

[0042] In one embodiment, see Figure 3 The above-mentioned driver 104 includes a signal input interface 1041, a deserializer 1042, an FPGA chip 1043, and an FPC interface 1044. The signal input interface 1041 is connected to the body control module; the signal input interface 1041 is connected to the deserializer 1042; the deserializer 1042 is connected to the FPGA chip 1043; the FPGA chip 1043 is connected to the FPC interface 1044; and the FPC interface 1044 is connected to the mini LED chip 101.

[0043] In one embodiment, see Figure 3 The above-mentioned FPC interface 1044 is also connected to a power controller 1045, and the power controller 1045 is connected to the power supply of the car 2 through a power input interface 1046.

[0044] Specifically, the lighting controller receives a 12V voltage, a GND signal, and a CAN signal from the body control module. The driver 104 interacts with the body control module using LVDS.

[0045] Specifically, a display interactive car light based on mini LED has two control modes. Control mode 1: The body control module supplies power and CAN signals to the light controller, the light controller controls the driver 104, and the driver 104 controls the mini LED chip 101 to display different symbols. When the car 2 travels to different states, such as steering, braking, etc., the body control module sends corresponding CAN signals to the light controller, the light controller interprets and processes the signals, and then sends signals to the driver 104, the driver 104 parses the signals, and controls the mini LED chip 101 to display corresponding symbols. Generally, the video source of road driving symbols is stored in the driver 104, and different video sources are called through different signals to quickly respond and display corresponding information. Control mode 2: Complex patterns, videos and other information, such as custom animations, holiday celebration welcome animations, personalized entertainment, etc., are directly input to the mini LED chip 101 through LVDS through the body control module for image interactive display. When the two signals conflict, for road safety considerations, the priority of the light controller signal will be set higher to ensure the smooth transmission of driving information.

[0046] Through this mini LED interactive light, complex, clear and delicate information transmission can be achieved, so that other vehicles and pedestrians can clearly know the vehicle's driving intentions, and information exchange between vehicles and between vehicles and people can be realized. At the same time, customized display patterns can be created to enhance the user experience.

[0047] The principle of the driver 104 is as follows: the driver 104 receives 12V power from the vehicle computer and the video signal / lighting controller input signal from the body control module. The 12V power is converted to 5V power through the DC / DC controller. The deserializer 1042 and FPGA chip 1043 receive the video signal from the host computer, perform image segmentation and data PWM correction, and output the display control signal to drive the mini LED chip 101 to display the image. Through DDR3 memory and Flash flash memory, it supports image storage, refresh, OTA upgrade and other functions.

[0048] In summary, the interactive display lights based on mini LED have two modes, which can display pre-stored videos and real-time videos. The light controller controls the display of simple road driving symbols; LVDS directly inputs real-time video from the car body to display personalized complex videos; based on driving safety, the signal priority of the light controller is higher than the signal priority of LVDS transmission.

[0049] Mini LED-based interactive car lights have the following benefits:

[0050] Clear and unambiguous information transmission: By displaying different symbols and patterns, vehicles can convey clear driving intentions and warning information to other vehicles and pedestrians, improving road safety.

[0051] Advanced customization and personalized experience: Car owners can customize display patterns and animations to make the vehicle more personalized, enhance the user experience and meet individual needs.

[0052] Can achieve complex and delicate display effects: mini LED technology has high brightness, high contrast and high color reproduction performance, which can present delicate and clear images and video effects.

[0053] Quick response and update function: Through the modes of pre-stored video and real-time video, the vehicle can quickly respond to display needs in different situations, and supports OTA upgrade function, so that functions and effects can be continuously updated and improved.

[0054] Improve traffic flow: Accurate driving intentions and warning information can help other vehicles and pedestrians better understand and predict the vehicle's behavior, thereby improving traffic flow and reducing accident risks.

[0055] In short, mini LED-based interactive car lights can provide safer, more personalized and high-quality information transmission and display effects, providing a better traffic experience for vehicles and pedestrians.

[0056] The above-mentioned mini LED-based display interactive car light, by setting a miniLED module 1 at the front end or rear end of a car 2, the miniLED module 1 includes a plurality of miniLED chips 101, and is packaged on a circuit board 102, and the size and center spacing of the miniLED chip 101 are limited to form a miniLED chip 101 with thousands / tens of thousands of pixels and a smaller spacing, so as to solve the problem that the current information interaction between cars 2 and cars 2, and between cars 2 and pedestrians is only light signals such as position, steering, braking, reversing, and honking, and the information is fuzzy and single. It also solves the problem that the current LED-based pixelated car lights have a large pixel spacing and cannot display complex and delicate patterns, and the interaction method between the car 2 and the environment is difficult to meet the diverse information needs of the future intelligent development of the car 2.
