[0002] With the growing demand for lighting effects in smart homes, stage performances, advertising displays and other fields, traditional lighting effect systems mainly rely on preset fixed modes and cannot be flexibly adjusted to meet different needs. Common types of existing lighting effect systems include lighting control systems based on preset modes, smart home lighting control systems and stage lighting control systems.

[0003] Lighting control systems based on preset modes: These systems usually adjust brightness and color through simple controllers and are commonly found in advertising screens and decorative lights, but they cannot respond to scene changes or user needs in real time.

[0005] Stage lighting control systems: These systems usually support dynamic lighting effects, but are complex to operate and difficult to customize.

[0006] The disadvantage of existing lighting effect systems is that they lack flexibility and adaptability. Specifically, most existing lighting control systems are limited to preset modes or simple brightness and color control, and cannot be adjusted in real time according to user needs or external environmental changes (such as sound, speed, ambient light intensity, etc.). This results in the performance of traditional lighting effect systems being limited in different application scenarios, especially those that require rapid response to environmental changes or provide personalized experiences.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] The present invention provides an atmosphere lamp lighting effect control method, which can significantly improve the flexibility and adaptability of the lighting system. By introducing a sensing module to collect external environmental data in real time and combining the preset algorithm to process and analyze the data, the system can automatically or manually adjust one or more parameters of the lighting effect (such as brightness, color value, number of colors, dynamic change speed, etc.) to achieve more intelligent and personalized lighting effects.

[0033] The details are as follows: In this embodiment, the ambient light effect control method is applied to a car as an example:

[0034] like Figure 1 As shown, a method for controlling the lighting effect of an ambient light in the present invention comprises the following steps:

[0035] Obtain environmental data: collect real-time data on changes in the external environment through the sensing module; further, such as Figure 2 As shown, the sensing module includes but is not limited to a sound sensor, a speed sensor, and a light intensity sensor, which are used to capture information on ambient volume, vehicle speed, or ambient light intensity, and transmit the information to the control unit for real-time adjustment.

[0036] The sensor module integrated inside the vehicle collects real-time data on changes in the external environment and dynamically adjusts the effect of the interior ambient light based on this data to provide a more personalized and interactive lighting experience.

[0037] Acquiring environmental data: The sensing module includes but is not limited to a sound sensor, a speed sensor, a light intensity sensor, etc., which is used to capture information about the ambient volume inside or around the vehicle, the vehicle speed, and the ambient light intensity.

[0038] For example, while the vehicle is driving, the sound sensor can capture the audio information of the music playing in the car; the speed sensor can monitor the speed changes of the vehicle; and the light intensity sensor can sense the light conditions inside and outside the car.

[0039] These sensors transmit the collected data to the central control unit (Control Unit), providing a basis for subsequent lighting effect adjustments.

[0040] Data analysis and processing: After the control unit receives the data transmitted by the sensing module, it will use the preset algorithm to analyze and process the data. For audio input, the system can identify the rhythm, frequency distribution and energy intensity of the music through fast Fourier transform (FFT) or other spectrum analysis techniques. For speed information, the system can select appropriate lighting effect modes according to different vehicle speed ranges, such as using a soft flashing effect at low speeds, and increasing the frequency and brightness of the lights at high speeds to enhance the sense of movement.

[0041] Light output adjustment:

[0042] Based on the results of data analysis, the system automatically adjusts one or more parameters of the ambient light, such as brightness, color value, number of colors, dynamic change speed, etc. When a strong rhythm of music is detected in the car, the ambient light can flash or change color synchronously to form a visual effect that matches the beat of the music. If it is night driving and the outside light is dim, the brightness of the ambient light is appropriately increased to ensure a clear field of vision for the driver while creating a comfortable driving atmosphere. During acceleration or deceleration, the color of the ambient light can gradually transition from cold to warm tones, and vice versa, simulating an effect similar to the change of daylight or the transition between day and night.

[0043] User-defined settings: Users can also personalize the ambient light effects through mobile phone apps, car systems or voice commands. For example, set the lighting effect combination for a specific scene, such as brighter and faster light changes in "sports mode" and softer and more gradual color flow in "leisure mode". In addition, users can set the separation point of the ambient light at any position, and execute the lighting effect to the left and right at the same time, creating a unique visual experience.

[0044] Through the application of the above method, the following significant technical effects are achieved:

[0045] Enhanced user experience: Through the intelligent ambient light control system, the vehicle can not only automatically adjust the lighting effects according to the actual driving conditions, but also support users to customize the lighting modes for different scenes according to their personal preferences, greatly improving the comfort and entertainment of the driver and passengers.

[0046] Improved safety: Especially at night or in bad weather conditions, reasonable adjustment of the brightness of the ambient light can help the driver pay more attention to the road conditions, reduce visual fatigue, and indirectly improve driving safety.

[0047] Energy saving and environmental protection: Intelligently adjusting the light brightness according to environmental changes avoids unnecessary energy waste, helps to extend the life of the lamp and reduce energy consumption, which is in line with the concept of modern green travel.

[0048] In summary, the vehicle ambient light lighting effect control method provided by the present invention not only solves the problem of lack of flexibility and adaptability of traditional lighting effect systems, but also brings users an unprecedented intelligent lighting experience through a highly personalized setting process and a multi-parameter adjustment mechanism.

[0049] Data analysis and processing: receiving and analyzing the data from the sensing module according to a preset algorithm; the core of this step is to receive and analyze the data from the sensing module according to a preset algorithm to achieve intelligent lighting effect adjustment. This process and the technical effects it brings can be better understood through the following specific embodiments:

[0050] Audio Signal Processing:

[0051] Spectrum analysis: When music is played in the car, the sound sensor captures the audio information and transmits it to the control unit. The control unit uses Fast Fourier Transform (FFT) to perform spectrum analysis on the audio signal and divide it into low-frequency, medium-frequency and high-frequency bands.

[0052] Low frequencies (such as drum sounds) are often used to drive large-scale light changes or dynamic effects, which may appear as flickering lights or dramatic changes in brightness.

[0053] The mid-frequency band can affect medium-scale lighting changes, such as color gradients or smooth transitions in brightness.

[0054] High frequencies (such as sharp high notes) may affect more subtle lighting effects, such as color changes or small brightness fluctuations.

[0055] Energy calculation: Calculate the energy intensity of the audio signal, which can be obtained through the root mean square (RMS) value or spectrum analysis. The stronger the audio energy, the more lamp beads will light up and the higher the brightness; conversely, when the audio energy is weak, the number of lamp beads and the brightness will decrease.

[0056] Rhythm recognition: By detecting peaks or re-beats in the audio signal, the rhythm of the music is identified and the brightness, color and dynamic changes of the lights are adjusted accordingly to synchronize the lights with the music.

[0057] Speed ​​data processing:

[0058] Vehicle speed sensor data: Get real-time vehicle speed information directly through the vehicle's speed sensor. The control unit selects different types of lighting effects according to different vehicle speed ranges.

[0059] Low speed (0-30km / h): Set the lights to stay on or use a soft flashing effect to create a relaxing and comfortable driving atmosphere.

[0060] Medium speed (30-60km / h): The light gradually becomes brighter, or the flashing frequency increases, forming a certain sense of rhythm.

[0061] High speed (above 60km / h): The light frequency increases, becomes brighter or flashes faster, enhancing the dynamic effect and reminding the driver to pay attention to safety.

[0062] GPS module assistance: Combined with the location and time interval information provided by the GPS module, the vehicle speed is further accurately calculated to ensure that the lighting effect matches the actual driving conditions.

[0063] Light intensity data processing:

[0064] Ambient light adaptation: The light intensity sensor is used to sense the light conditions inside and outside the car. When the external light is strong, the brightness of the ambient light is appropriately reduced to avoid glare; at night or in a dim environment, the brightness is increased to ensure a clear field of vision for the driver and passengers.

[0065] Automatic dimming: According to the changes in ambient light intensity, the system automatically adjusts the brightness of the atmosphere light to maintain optimal visual comfort while also achieving energy-saving effects.

[0066] Comprehensive Data Fusion:

[0067] Multi-source data integration: The control unit not only processes the data from each sensor individually, but also conducts a comprehensive analysis of the data, taking into account the influence of multiple factors to provide more intelligent and personalized lighting effects.

[0068] Scene mode switching: Based on comprehensive analysis results, the system can automatically switch to preset lighting modes in different driving scenarios, such as "city driving mode", "highway mode", "night mode", etc. Each mode has a unique lighting configuration to suit specific driving needs.

[0069] Through the application of the above data analysis and processing steps, the following significant technical effects are achieved:

[0070] Enhanced interactivity and personalization: The system can adjust the lighting effects in real time according to multiple factors such as music rhythm, vehicle speed and ambient light intensity, providing a highly personalized lighting experience, making driving more interesting and comfortable.

[0071] Improved safety: Especially at night or in bad weather conditions, reasonable adjustment of light brightness can help drivers pay more attention to road conditions, reduce visual fatigue, and indirectly improve driving safety.

[0072] Intelligent energy saving is achieved: the brightness is automatically adjusted according to the ambient light intensity, avoiding unnecessary energy waste, helping to extend the life of the lamp and reduce energy consumption, which is in line with the concept of modern green travel.

[0073] Improved system flexibility and adaptability: Through the fusion processing of multi-source data, the system can adaptively adjust in various complex driving environments, meet the diverse needs of users, and improve the overall user experience.

[0074] Lighting output adjustment: automatically adjust one or more parameters of the lighting effect according to the result of data analysis. Further, the one or more parameters of the lighting effect include brightness, color value, number of colors, dynamic change speed, gradient rate, entry and exit effect, direction, number of repetitions and separation point.

[0075] In this embodiment, the specific application of the "light output adjustment" step in the vehicle atmosphere light system will be discussed in detail. The core of this step is to automatically adjust one or more parameters of the lighting effect according to the results of data analysis. Through the following specific embodiments, you can better understand this process and the technical effects it brings.

[0076] Brightness adjustment:

[0077] Based on audio energy: When music is played in the car, the control unit dynamically adjusts the brightness of the ambient light according to the energy intensity of the audio signal (such as the root mean square value RMS). For example, in the bass section (such as drums), the brightness will suddenly increase to match the strong rhythm; while in the treble section (such as violin melody), the brightness will gradually soften.

[0078] Based on vehicle speed changes: Based on the data from the vehicle speed sensor, the system automatically adjusts the brightness of the ambient light. For example, when driving at low speeds, the brightness is kept low but sufficient; as the vehicle speed increases, the brightness also increases, enhancing the driver's attention and alertness.

[0079] Color value adjustment:

[0080] Music-synchronized color change: The system uses spectrum analysis to identify the different frequency components of the music, and selects the corresponding colors for display. Low-frequency bands may correspond to warm tones (such as red and orange), while high-frequency bands correspond to cool tones (such as blue and purple). This synchronized change of color with music increases visual pleasure.

[0081] Scene mode color matching: Users can preset color configurations for different scenes through the mobile phone APP or the car system. For example, bright and high-contrast color combinations are used in "sports mode", and soft and gradual color flow is preferred in "leisure mode".

[0082] Color quantity adjustment:

[0083] Multi-color gradient: Users can set the number of colors involved in a gradient. For example, set a rainbow transition from red to purple to form a complete color spectrum effect. After each update, the colors will gradually change in a predetermined order, simulating the color flow in nature.

[0084] Random color switching: For more random and dynamic effects, the system can generate random color values ​​for each LED in each cycle, ensuring that the overall effect is full of changes and surprises.

[0085] Dynamic change speed adjustment:

[0086] Music rhythm synchronization: According to the rhythm of the music, adjust the speed of light changes. For example, when the strong sound of the music appears, the light changes faster, which enhances the sense of synchronization between the two.

[0087] Time delay control: By setting the time delay between different LEDs, you can create a continuous flow effect, such as the movement of light and shadow like flowing water, or the feeling of undulating waves.

[0088] Gradient rate adjustment:

[0089] Smooth Transition: Defines the smoothness of the color transition, that is, the step size when changing from one color to another. A larger step size means faster color transitions, suitable for expressing strong emotional fluctuations; a smaller step size creates delicate and smooth changes, suitable for relaxation and meditation scenes.

[0090] Adjustments to entry and exit effects:

[0091] Dynamic entrance: Set the way the light enters, such as gradually expanding from one side to the other, or spreading outward from the center. This method not only increases the visual impact, but also guides the line of sight and enhances the sense of space hierarchy.

[0092] Elegant Exit: When the lights exit, you can choose to gradually dim until they are completely extinguished, or disappear instantly, leaving a deep impression.

[0093] Direction Adjustment:

[0094] One-way flow: Light can flow in one direction, from left to right or from top to bottom, simulating water flow or other natural phenomena.

[0095] Bidirectional flow: Flowing in two opposite directions at the same time, creating a symmetrical and harmonious beauty.

[0096] Adjust the number of repetitions:

[0097] Loop Mode: Set the number of times the lighting effect is looped. It can be either an infinite loop or a one-time special effect display, such as during holiday celebrations or special events.

[0098] Split point setting:

[0099] Multi-point concurrency: Users can set the separation point of the ambient light at any position, and execute the lighting effect to the left and right at the same time to create a unique visual experience. For example, inside the car, the two sides of the front seat can be set as the separation point to achieve a symmetrical lighting effect.

[0100] By applying the above-mentioned light output adjustment method, the following significant technical effects are achieved:

[0101] Highly personalized customization: Users can flexibly adjust the parameters of the atmosphere light according to their personal preferences and actual needs. Whether it is a static fixed mode or a dynamic interactive effect, it can be satisfied, greatly improving user satisfaction and sense of participation.

[0102] Enhanced interactivity and immersion: The system can adjust the lighting effects in real time according to multiple factors such as music rhythm, vehicle speed and ambient light intensity, providing a more intelligent and personalized lighting experience, making the driver and passengers feel as if they are in an artistic space that can be freely controlled.

[0103] Improved safety and comfort: Especially at night or in bad weather conditions, reasonable adjustment of light brightness can help drivers pay more attention to road conditions, reduce visual fatigue, and indirectly improve driving safety. At the same time, a comfortable lighting environment can also help relieve driving pressure and improve the riding experience.

[0104] Intelligent energy saving is achieved: the brightness is automatically adjusted according to the ambient light intensity, avoiding unnecessary energy waste, helping to extend the life of the lamp and reduce energy consumption, which is in line with the concept of modern green travel.

[0105] In another embodiment, the method further comprises:

[0106] User-defined settings: Users can personalize lighting effects through a variety of interactive methods, including at least mobile phone applications, vehicle systems or voice commands.

[0107] User-defined settings further include:

[0108] After setting any point of the physical position of the lighting effect as the separation point, the lighting effect is executed simultaneously to the left and right to create a visual effect.

[0109] This step allows the user to personalize the lighting effect through a variety of interactive methods, including at least mobile phone applications, vehicle systems or voice commands. In addition, the user can also set any point of the physical location of the lighting effect as a separation point, and execute the lighting effect to the left and right at the same time to create a unique visual effect. The following specific examples can better understand this process and the technical effects it brings.

[0110] Diversified interaction methods:

[0111] Mobile App: Users can remotely control the effects of the interior ambient lighting through a dedicated application (APP) on their smartphones. The APP provides an intuitive interface that allows users to select preset modes, adjust parameters such as brightness, color value, dynamic change speed, and preview the effects in real time.

[0112] Car system: Modern cars are usually equipped with advanced in-vehicle infotainment systems (IVI), which allow users to directly operate on the central control screen and select lighting modes for different scenarios, such as "sports mode", "leisure mode" or "night mode". The car system also supports saving user preferences for easy use next time.

[0113] Voice command: With integrated voice assistants (such as Alibaba Tongyi), users can quickly adjust the lighting effects by simply issuing simple voice commands, such as "turn on relaxation mode", "brighten the atmosphere light", "switch to blue gradient".

[0114] Separation point setting and multi-point concurrent lighting effects:

[0115] Separation point setting: Users can set one or more separation points at any position of the ambient light strip. For example, inside the car, users can choose the two sides of the front seats as separation points, or the rear center armrest as the separation point to achieve symmetrical or asymmetrical lighting effects.

[0116] Multi-point concurrent lighting effects: When the separation point is set, the system will start from that point and execute the lighting effects to the left and right at the same time, creating a unique visual effect. For example:

[0117] Two-way flow effect: Starting from the separation point, the light flows to both sides at the same time, simulating water flow or other natural phenomena, increasing the visual impact.

[0118] Symmetrical flashing effect: The lights on both sides of the separation point can flash synchronously, forming a symmetrical and harmonious beauty, suitable for celebrations or special occasions.

[0119] Gradual transition effect: Starting from the separation point, the color of the light gradually changes, forming a smooth color transition, creating a soft and elegant atmosphere.

[0120] Scene mode presets and customization:

[0121] Preset mode: The system has built-in multiple preset scene modes, such as "sports mode", "leisure mode", "night mode", etc. Each mode has a specific lighting configuration to meet the needs of different driving scenarios.

[0122] Custom Modes: Users can create and save custom lighting modes based on their personal preferences. For example, users can set specific color combinations, dynamic change speeds, brightness adjustments, and even record and sync with music to create a unique light show.

[0123] Real-time preview and instant adjustment:

[0124] Real-time preview: Whether through the mobile phone APP or the car system, users can preview the lighting effects to be applied in real time to ensure that the final effect meets expectations.

[0125] Instant adjustment: If the user is not satisfied with the current effect, he can adjust it at any time until he is satisfied. All changes will take effect immediately without restarting the system.

[0126] Technical Effects

[0127] By applying the above user-defined setting method, the following significant technical effects are achieved:

[0128] Highly personalized customization: Users can flexibly adjust the parameters of the atmosphere light according to their needs and preferences, whether it is a static fixed mode or a dynamic interactive effect, which can be satisfied, greatly improving user satisfaction and sense of participation.

[0129] Enhanced interactivity and immersion: The diverse interaction methods allow users to easily adjust the lighting effects anytime and anywhere, increasing the interactivity between the vehicle and the vehicle. Separation point settings and multi-point concurrent lighting effects provide users with more creative possibilities, making the driving experience more colorful.

[0130] Improved safety and comfort: Especially at night or in bad weather conditions, reasonable adjustment of light brightness can help drivers pay more attention to road conditions, reduce visual fatigue, and indirectly improve driving safety. At the same time, a comfortable lighting environment can also help relieve driving pressure and improve the riding experience.

[0131] Simplified operation process: Through intuitive interface design and convenient voice control, ordinary users can easily configure and adjust lighting effects without complex professional knowledge, reducing learning costs and technical barriers.

[0132] Promoted user experience innovation: User customization is not limited to existing functions, but also encourages users to explore new lighting effect combinations, stimulates creative inspiration, and promotes continuous innovation in lighting technology and user experience.

[0133] In another embodiment, the method further comprises:

[0134] Audio synchronization: Get sound signals through audio input, analyze changes in frequency and volume in real time, adjust the brightness, color and dynamic changes of lights, and synchronize lights with music.

[0135] Audio synchronization further includes one or more of rhythm lighting effects, frequency lighting effects, and energy lighting effects, and corresponding lighting control parameters are mapped according to different characteristics of the audio signal.

[0136] In this embodiment, the specific application of the "audio synchronization" step in the vehicle atmosphere light system will be discussed in detail. This step obtains the sound signal through the audio input, analyzes the changes in frequency and volume in real time, adjusts the brightness, color and dynamic changes of the light, and synchronizes the light with the music. Through the following specific embodiments, you can better understand this process and the technical effects it brings.

[0137] Audio signal acquisition:

[0138] Microphone or amplifier input: A highly sensitive microphone installed in the car or an amplifier connected directly to the car audio system is used to capture high-quality audio signals.

[0139] Multi-channel support: To achieve more sophisticated audio analysis, the system supports multi-channel audio input and can distinguish the location and characteristics of different sound sources, such as the difference between the left and right channels.

[0140] Spectral analysis and feature extraction:

[0141] Fast Fourier Transform (FFT): Use the FFT algorithm to perform spectrum analysis on the audio signal, decompose it into low-frequency, medium-frequency and high-frequency bands, and identify different frequency components.

[0142] Peak Detection: By detecting the peaks or re-beats in the audio signal, the rhythm of the music is identified and the brightness, color and dynamic changes of the lights are adjusted accordingly to synchronize the lights with the music.

[0143] Energy calculation: Calculate the energy intensity of the audio signal, which can be obtained through the root mean square (RMS) value or spectrum analysis. The stronger the audio energy, the more lamp beads will light up and the higher the brightness; conversely, when the audio energy is weak, the number of lamp beads and the brightness will decrease.

[0144] Lighting Effects Mapping:

[0145] Rhythm lighting effect: adjust the lighting effect in real time according to the rhythm of the music. For example, when the strong note (beat) of the music appears, the light will change sharply in brightness, and even change color to enhance the effect. Each strong beat can be detected and converted into a control signal for the light, so that the light flashes or changes color in line with the rhythm of the music.

[0146] Frequency lighting effect:

[0147] Low-frequency response: Low frequencies (such as drum sounds) are often used to drive large light changes or dynamic effects, which may appear as flickering lights or dramatic changes in brightness.

[0148] Mid-frequency response: The mid-frequency band can affect medium-scale lighting changes, such as color gradients or smooth transitions in brightness.

[0149] High-frequency response: High frequencies (such as sharp high notes) may affect more subtle lighting effects, such as color changes or small brightness fluctuations.

[0150] Energy Lighting Effect: Adjusts the brightness and color of the light according to the energy intensity of the audio signal. When the audio energy is strong, more lamp beads will be lit and the brightness will be higher; when the audio energy is weak, the number and brightness of the lamp beads will decrease, creating a softer effect.

[0151] Comprehensive lighting effects:

[0152] Multi-dimensional mapping: The system not only processes data from each frequency band individually, but also conducts a comprehensive analysis of the data, taking into account the influence of multiple factors to provide more intelligent and personalized lighting effects.

[0153] Scene mode switching: Based on comprehensive analysis results, the system can automatically switch to preset lighting modes in different driving scenarios, such as "city driving mode", "highway mode", "night mode", etc. Each mode has a unique lighting configuration to suit specific driving needs.

[0154] By applying the above audio synchronization method, the following significant technical effects are achieved:

[0155] Enhanced interactivity and immersion: The perfect synchronization of lighting and music not only enhances the visual pleasure, but also creates a more immersive driving experience. Users seem to be in an art space where they can do whatever they want, and feel the unique charm of each piece of music.

[0156] Improved level of personalized customization: Users can flexibly adjust the lighting effects according to the type of music and personal preferences, whether it is a static fixed mode or a dynamic interactive effect, which can be satisfied, greatly improving user satisfaction and sense of participation.

[0157] Enriched lighting expressions: By combining rhythm lighting effects, frequency lighting effects and energy lighting effects, the system can show more diverse and delicate lighting changes to meet the needs of different scenarios. For example, it can create a warm atmosphere at a party and provide a soothing lighting environment at a relaxing moment.

[0158] Simplified operation process: Through intuitive interface design and convenient voice control, ordinary users can easily configure and adjust lighting effects without complex professional knowledge, reducing learning costs and technical barriers.

[0159] Promotes innovation in user experience: The audio synchronization function is not limited to existing functions, but also encourages users to explore new combinations of lighting effects, stimulates creative inspiration, and promotes continuous innovation in lighting technology and user experience.

[0160] In another embodiment, the method further comprises:

[0161] Speed ​​response: Obtain vehicle speed information through vehicle speed sensor, GPS module or other hardware modules, and adjust the lighting effect accordingly.

[0162] Furthermore, in the speed response, different types of lighting effects are selected according to different vehicle speed ranges, including: using a soft flickering effect at low speeds and increasing the lighting frequency and brightness at high speeds.

[0163] In this embodiment, the specific application of the "speed response" step in the vehicle atmosphere light system will be discussed in detail. This step obtains vehicle speed information through a vehicle speed sensor, GPS module or other hardware module, and adjusts the lighting effect accordingly. Through the following specific embodiments, you can better understand this process and the technical effects it brings.

[0164] Vehicle speed data collection:

[0165] Vehicle speed sensor: Get real-time vehicle speed information directly through the vehicle's speed sensor. These sensors are usually integrated into the vehicle's electronic control system and can provide accurate speed readings.

[0166] GPS module: Use the global positioning system (GPS) module to obtain the vehicle's location and time interval information, and then calculate the vehicle speed. This method is particularly suitable for old models or modified cars that do not have a built-in speed sensor.

[0167] Other hardware modules: Vehicle speed information can also be obtained through the vehicle CAN bus interface, radar sensor, inertial measurement unit (IMU) and other devices. For example, IMU combines the data of accelerometer and gyroscope to estimate the vehicle's acceleration change and driving direction to calculate the vehicle speed; radar sensor indirectly calculates the vehicle speed by measuring the relative speed with surrounding objects.

[0168] Speed ​​range division and lighting effect mapping:

[0169] Low speed mode (0-30km / h):

[0170] Soft flashing effect: When the vehicle is driving at a low speed, the ambient light uses a soft flashing effect to create a relaxed and comfortable driving atmosphere. This lighting effect is suitable for short-distance driving in congested urban roads and reduces the psychological pressure on drivers.

[0171] Moderate brightness: Maintain a low but sufficient brightness to avoid glare while ensuring that the interior environment of the car is bright and comfortable.

[0172] Medium speed mode (30-60km / h):

[0173] Gradual enhancement effect: As the vehicle speed increases, the lights gradually become brighter or flash faster, creating a certain rhythm. This helps to increase the driver's attention, especially on suburban roads or near highway entrances.

[0174] Color change: A color gradient effect can be introduced, gradually transitioning from warm tones (such as orange and yellow) to cool tones (such as blue), simulating the effect of transitioning from day to night.

[0175] High speed mode (above 60km / h):

[0176] High-frequency flashing and high brightness: When the vehicle enters a high-speed driving state, the light frequency increases, becomes brighter or flashes quickly, enhancing the dynamic feeling and reminding the driver to pay attention to safety. This lighting effect is particularly suitable for long-distance driving or highway driving.

[0177] Dynamic changes: In addition to changes in brightness and flashing frequency, you can also add dynamic change effects, such as wave effects or flowing light effects, to further enhance the visual impact.

[0178] Comprehensive lighting effects adjustment:

[0179] Multi-dimensional mapping: The system not only processes the data from the vehicle speed sensor alone, but also comprehensively analyzes this data with information from other sensing modules (such as sound sensors and light intensity sensors), taking into account the influence of multiple factors to provide more intelligent and personalized lighting effects.

[0180] Scene mode switching: Based on comprehensive analysis results, the system can automatically switch to preset lighting modes in different driving scenarios, such as "city driving mode", "highway mode", "night mode", etc. Each mode has a unique lighting configuration to suit specific driving needs.

[0181] Through the application of the above speed response method, the following significant technical effects are achieved:

[0182] Enhanced interactivity and safety: Automatically adjusting the lighting effects according to vehicle speed not only improves the visual experience of drivers and passengers, but also helps drivers pay more attention to road conditions, reduces visual fatigue, and indirectly improves driving safety. Especially when driving at high speeds, high-frequency flashing and high-brightness lighting effects can effectively remind drivers to stay alert.

[0183] Improved level of personalized customization: Users can flexibly adjust the lighting effects according to actual driving scenarios, whether it is a static fixed mode or a dynamic interactive effect, which can be satisfied, greatly improving user satisfaction and sense of participation.

[0184] Enriched lighting expressions: By combining vehicle speed, audio signals and other environmental factors, the system can show more diverse and delicate lighting changes to meet the needs of different scenarios. For example, it can create a relaxing atmosphere when driving in the city, while providing strong visual stimulation on the highway.

[0185] Simplified operation process: Through the intelligent automatic adjustment mechanism, ordinary users do not need to manually adjust the lighting settings frequently, which reduces the complexity of operation and technical threshold, making driving easier and more convenient.

[0186] Promoted user experience innovation: The speed response function is not limited to existing functions, but also encourages users to explore new lighting effect combinations, stimulates creative inspiration, and promotes continuous innovation in lighting technology and user experience.

[0187] In summary, the speed response method provided by the present invention not only solves the problem of lack of flexibility and adaptability of traditional lighting effect systems, but also provides users with more intelligent and personalized lighting solutions through intelligent data processing mechanisms and humanized interactive design, significantly improving user experience and technical value. In addition, the speed response function is particularly suitable for adaptive adjustment under different driving conditions, greatly enhancing the functionality and fun of the vehicle as a mobile space.

[0188] In addition, the present invention also proposes an atmosphere lamp lighting effect control system, such as Figure 3 As shown, it includes: a control unit, a sensing module and a user interaction interface; wherein the control unit is responsible for receiving data from the sensing module and processing and analyzing it according to a preset algorithm, and the user interaction interface supports user-defined lighting effect configuration.

[0189] Control unit:

[0197] Other sensors: Temperature sensors, humidity sensors, etc. can also be integrated to further enrich the data source and provide a basis for smarter lighting adjustments.

[0198] User interaction interface:

[0199] Mobile App: Users can remotely control the effects of the interior ambient lighting through a dedicated app on their smartphones. The app provides an intuitive interface that allows users to select preset modes, adjust parameters such as brightness, color value, dynamic change speed, and preview the effects in real time.

[0200] Car system: Modern cars are usually equipped with advanced in-vehicle infotainment systems (IVI), which allow users to directly operate on the central control screen and select lighting modes for different scenarios, such as "sports mode", "leisure mode" or "night mode". The car system also supports saving user preferences for easy use next time.

[0201] Voice command: With integrated voice assistants (such as Alibaba Tongyi), users can quickly adjust the lighting effects by simply issuing simple voice commands, such as "turn on relaxation mode", "brighten the atmosphere light", "switch to blue gradient".

[0202] Comprehensive control logic:

[0203] Multi-source data fusion: The control unit not only processes the data from each sensor individually, but also conducts a comprehensive analysis of the data, taking into account the influence of multiple factors to provide more intelligent and personalized lighting effects.

[0204] Scene mode switching: Based on comprehensive analysis results, the system can automatically switch to preset lighting modes in different driving scenarios, such as "city driving mode", "highway mode", "night mode", etc. Each mode has a unique lighting configuration to suit specific driving needs.

[0205] Separation point setting and multi-point concurrent lighting effects:

[0206] Separation point setting: Users can set one or more separation points at any position of the ambient light strip. For example, inside the car, users can choose the two sides of the front seats as separation points, or the rear center armrest as the separation point to achieve symmetrical or asymmetrical lighting effects.

[0207] Multi-point concurrent lighting effects: When a separation point is set, the system will start from that point and execute lighting effects to the left and right at the same time, creating unique visual effects, such as bidirectional flow effects, symmetrical flashing effects, or gradual transition effects.

[0208] Through the design and application of the above-mentioned atmosphere light lighting effect control system, the following significant technical effects are achieved:

[0209] Enhanced interactivity and personalized customization: Users can flexibly adjust the parameters of the atmosphere light according to their needs and preferences.

At the same time, a comfortable lighting environment can also help relieve driving pressure and improve the riding experience.

[0211] Simplified operation process: Through intuitive interface design and convenient voice control, ordinary users can easily configure and adjust lighting effects without complex professional knowledge, reducing learning costs and technical barriers.

[0212] Promoted user experience innovation: User customization is not limited to existing functions, but also encourages users to explore new lighting effect combinations, stimulates creative inspiration, and promotes continuous innovation in lighting technology and user experience.

[0213] It has achieved intelligence and energy saving: it automatically adjusts the brightness according to the ambient light intensity, avoiding unnecessary energy waste, helping to extend the life of the lamp and reduce energy consumption, which is in line with the concept of modern green travel.

[0214] In another embodiment, if Figure 4 As shown, the description of gradient calculation:

[0215] like Figure 4 Gradient calculation graph, the gradient step length is 5 (0 to 5), 6 steps from red to blue, and 4 intermediate gradient colors from red to blue are obtained respectively.

[0216] Overall color gradient

[0217] Definition: The overall mood light transitions smoothly from one color to another.

[0218] Implementation: The process of using gradient to calculate the overall gradient.

[0219] For example, the above (gradient calculation diagram) is from red to blue, and there is an ambient light strip with 100 lights. The first time all the lights are displayed in red, and the cycle is executed once every 20ms. The second cycle displays the first gradient color from red to blue (r: 204, g: 0, b: 51), and the third cycle displays the second gradient color (r: 153, g: 0, b: 102). And so on, a gradient effect of color arrangement is obtained. The above design can also be used for the gradient of brightness, and then it becomes a breathing effect (the above parameters can be set, the gradient step size, and the number of colors are not limited to the above values).

[0220] Segment Color

[0221] Definition: A rainbow-like transition from red to purple is achieved through a length gradient composed of multiple LED lamp beads, forming a complete color spectrum effect. For example, a light strip consists of 100 lamps, and the gradient step is set to 5, and the colors are red, orange, yellow, green, blue, indigo, and purple (not limited to these colors); first, it gradually changes from red to orange, where the first lamp is red, and the 2nd to 5th lamps are gradient colors from red to orange, and then the target color is changed, from orange to yellow, the 6th lamp is orange, and the 7th to 10th lamps are gradient colors from orange to yellow, and so on, and it keeps looping. Different effects will be obtained by setting the flow or overlay effect (the above parameters can be set, the gradient step, and the number of colors are not limited to the above values).

[0222] Flow effect: Move the colors displayed by the light strip backwards. For example, if the first light is red, calculate the first gradient color A from red to orange, and then move the red color of the first light to the next light, and the first light displays the gradient color A. And so on, you can get a gradient rainbow atmosphere light effect similar to flowing water.

[0223] Overlay effect: Overlay effect will be used. For example, the first light shown above is red. The first gradient color A from red to orange is calculated and used for the second light. And so on, the color value is continuously changed to obtain a gradient rainbow atmosphere light effect with an overlay effect.

[0224] Implementation:

[0225] Segmented color gradients require setting multiple color segments to simulate a rainbow-like color spectrum. The color spectrum is usually divided into multiple parts, such as red, orange, yellow, green, blue, indigo and purple, with smooth transitions between each segment.

[0226] By cyclically controlling the colors of multiple LED beads, each bead of the LED light strip can display a color in the color spectrum, thus forming an overall rainbow-like effect.

[0227] Color temperature gradient

[0228] Definition: Gradually change from cold light (such as bluish-white light) to warm light (such as yellow light) to simulate the atmosphere changes of different environments. Common applications are to simulate daylight changes or the transition between day and night.

[0229] Implementation:

[0230] The transition of color temperature is generally achieved by adjusting the color temperature value of the LED. Cold light usually contains more blue and a small amount of red, while warm light contains more red and yellow. By adjusting the RGB components, the blue component is gradually reduced while the red and green components are increased, thus achieving a smooth transition from cold light to warm light.

[0231] In summary, the ambient light control system provided by the present invention not only solves the problem of lack of flexibility and adaptability of the traditional lighting effect system, but also provides users with a more intelligent and personalized lighting solution through intelligent data processing mechanism and humanized interactive design, significantly improving user experience and technical value. In addition, the system is particularly suitable for adaptive adjustment under different driving conditions, greatly enhancing the functionality and fun of the vehicle as a mobile space.
