Description

Technical Field

[0001] The present invention relates to an LED smart panel lamp, specifically an LED smart panel lamp integrating lighting, audio playback, environmental perception and intelligent control, belonging to the technical field of smart home lighting equipment. Background Art

[0002] With the transformation of modern lifestyles and advancements in technology, people's demand for indoor lighting is no longer limited to basic lighting functions. Instead, they pursue a more intelligent and personalized lighting experience. LED panel lights, with their simple and beautiful appearance and uniform and soft lighting, have been widely used in the field of indoor lighting.

[0003] However, most existing LED panel lights on the market have only a single function and are controlled directly via panel switches. They lack intelligent and personalized lighting solutions and fail to meet consumers' higher demands for aesthetic and comfortable lighting environments. Therefore, there is a need to develop an LED smart panel light that can integrate multiple functions, achieve intelligent control, and enhance the user experience.

[0004] The solution of the present invention focuses on integrating light sources, voice recognition, and speaker playback modules, and combines them with Wi-Fi or Bluetooth technology to achieve intelligent control and mode customization of lights and provide richer and more flexible lighting solutions based on the user's specific needs and usage scenarios. Through infrared sensors or cameras combined with image processing technology, smart panel lights can detect the number of people in the room in real time and automatically or manually set a variety of smart scene modes based on the number of people, time period, and user habits, such as waking up early, taking a lunch break, watching TV, reading before bed, listening to music, and family gatherings, etc., achieving one-click switching, greatly enhancing the user's smart life experience. In addition, LED smart panel lights can not only provide basic lighting functions, but can also interact with other indoor electrical equipment through intelligent technology to improve the user's quality of life and meet the diverse needs of modern consumers for indoor lighting. Summary of the Invention

[0005] In response to the problems in the existing technology that LED panel lights have single functions, low intelligence, and difficulty in meeting users' personalized needs, the purpose of the present invention is to provide a multimedia-integrated LED smart panel light that can realize the functions of multimedia playback and lighting background linkage, intelligent environmental perception and personalized lighting adjustment, thereby providing a richer lighting solution and user experience.

[0006] The technical solutions of the present invention for solving the above problems are as follows:

[0007] A multimedia-integrated LED smart panel light comprises a control module, a storage module, a sensor module, a wireless transmission module, a multimedia interaction module, a power supply module, and an intelligent sensing module. The control module uses an infrared sensor or camera within the intelligent sensing module, combined with image processing technology, to detect the number of people in a room in real time. It then automatically or manually sets various intelligent scene modes based on the number of people, time period, and user habits, enhancing the user's smart living experience. A microphone within the intelligent sensing module captures audio signals in real time, and the control module uses digital signal processing technology to analyze the volume, frequency, and rhythm. This analysis combines the number of people monitored by the camera within the intelligent sensing module with the light information acquired by the sensor module to achieve synchronized sound and light control. The control module is controlled by an external smart home management system or by combining light, temperature, humidity, and PIR sensor information acquired by the sensor module. When the sensor module detects environmental changes, it collects and processes data signals, which are then transmitted to the control module via the wireless transmission module. After analyzing these signals, the control module generates instructions and sends them to the corresponding devices, enabling dynamic linkage between other electrical devices and the light fixture.

[0008] As a preferred technical solution of the present invention, the sensor module is responsible for collecting room light intensity information, temperature and humidity information, and human movement information; the wireless transmission module is responsible for receiving control requirements from the terminal and sending information to the mobile terminal; the multimedia interaction module is used to achieve the linkage effect of lighting and audio; the intelligent perception module respectively detects the information of people in the room and the instructions issued by people; the information of each sensor module can communicate bidirectionally with the control module. The information of each module is transmitted to the control module, and the control module controls the current of each LED lamp bead string through the driver module according to the environmental information, thereby achieving environmental adaptive adjustment of the lamp.

[0009] By combining the infrared sensor or camera in the intelligent sensing module with image processing technology, the control module can detect the number of people in the room in real time, and automatically or manually set a variety of intelligent scene modes according to the number of people, time period and user habits, thereby enhancing the user's smart life experience. The microphone in the intelligent sensing module captures audio signals in real time, and the control module uses digital signal processing technology to analyze the volume, frequency and rhythm, and combines the number of people monitored by the camera in the intelligent sensing module and the light information obtained by the sensor module to achieve synchronous sound and light control. Through the smart home management system, combined with the light information, temperature and humidity information and PIR sensor information obtained by the sensor module, when the sensor module detects environmental changes, it generates data signals through collection and processing, and transmits the data signals to the control module wirelessly. After the system parses these signals, it generates instructions and sends them to the corresponding devices, realizing dynamic linkage between the home and the lamps.

[0010] Working principle of the present invention:

[0011] A multimedia-integrated LED smart panel light primarily includes a control module, a storage module, a sensor module, a wireless transmission module, a multimedia interaction module, a power module, and an intelligent sensing module. The sensor module consists of a PIR sensor module, a temperature and humidity sensor (including a temperature sensor module and a humidity sensor module), and a light sensor module.

[0012] The intelligent perception module obtains the RGB image of the current environment through the camera, and the control module applies Gaussian blur filtering to smooth the image. The core of Gaussian blur is the Gaussian function, which is calculated as follows:

[0013]

[0014] Where x and y are the coordinates of the pixel location, and σ is the standard deviation, which determines the intensity of the blur. The larger the standard deviation, the more pronounced the blur effect.

[0015] This processing method removes brightness variations and noise from the image, ensuring the purity of the image information and laying the foundation for subsequent feature extraction. The image data after Gaussian blur processing is input into the convolutional neural network (CNN) within the control module. The CNN extracts image features layer by layer through multiple convolutional layers, classifying information such as furniture, decorations, and spatial layout in the environment to identify the room type. Based on the CNN analysis results, the system determines the current room type (such as bedroom, living room, kitchen, etc.). Based on the room type, the system automatically sets the corresponding lighting parameters, adjusting the color temperature and brightness of the LED lights. For example, in the bedroom, the system is set to warm white light with a color temperature between 2700K and 3500K to create a warm and comfortable atmosphere. In the living room, the system is set to neutral white light with a color temperature between 4000K and 5000K to provide bright, natural lighting. In the kitchen, the system is set to cool white light with a color temperature between 5000K and 6500K to enhance the brightness of the space and facilitate operation and cleaning. Based on the system's automatic settings, users can also manually adjust the brightness and color temperature of the lights through the control panel or voice commands, greatly satisfying the user's personalized lighting needs.

[0016] In the movie viewing mode, the multimedia interactive module automatically turns off the main light, and the LED side lights cast soft light on the TV wall. The microphone in the intelligent sensing module captures the audio signal in real time, and the control module uses digital signal processing technology to extract key audio features including volume, frequency, and rhythm changes. The volume is calculated as follows:

[0017]

[0018] Where: N is the total number of sampling points; x[n] is the amplitude of the nth sampling point. The volume calculated as the RMS value reflects the intensity of the audio. The system dynamically adjusts the lighting brightness based on the volume level. When the volume is high, the lighting brightness increases; when the volume is low, the brightness decreases, creating a lighting atmosphere that suits the audio environment.

[0019] Frequency is the embodiment of pitch. Fast Fourier Transform (FFT) can be used to convert audio signals from the time domain to the frequency domain to identify the main frequency components. Through FFT analysis, the fundamental frequency and harmonic frequencies in the audio can be identified, providing a basis for the color and effect of the lighting. The frequency calculation method is as follows:

[0020]

[0021] Where: X[K] represents the complex value of the Kth frequency component (including amplitude and phase), e -j·2π·k·n / Nis the complex exponential rotation factor. The frequency components obtained by FFT can help the system identify the main frequency changes. The system uses these frequency components to control the color and distribution effects of the lights. In audio and video entertainment mode, when the system recognizes that the low-frequency components (such as heavy bass) in the audio signal are between 20Hz-200Hz, the system adjusts the lights to warm red and increases its brightness and flickering frequency to enhance the immersiveness of the audio effect. When the system recognizes that the mid-frequency components in the audio signal are between 200Hz-2kHz, the system adjusts the lights to warm white. At the same time, when the system recognizes that the high-frequency components in the audio (such as high-pitched instruments or sound effects) are between 2kHz-20kHz, the system adjusts the lights to cool blue and reduces the flickering frequency of the lights, so that the visual effects of the entire environment are perfectly synchronized with the rhythm and characteristics of the audio.

[0022] Rhythm is the rhythmic characteristic of audio. The system calculates the rhythm rate R (in BPM) of the audio by periodic peak detection. The rhythm calculation method is as follows:

[0023]

[0024] Where: f s is the sampling rate (the number of samples per second), and t is the time interval between the peaks of adjacent beats of the audio signal. The rhythm rate detected by the system is used to control the flashing frequency of the lights, synchronizing the flashing of the lights with the audio rhythm to achieve synchronization of the lights and audio, enhancing the audio-visual effect. In audio-visual entertainment mode, when a slow jazz track is detected, assuming the calculated R is 60 BPM, indicating 60 beats per minute (i.e., 1 beat per second), the flashing frequency of the lights will be set to 1 Hz, i.e., once per second. The changing rhythm of the lights perfectly matches the rhythm of the music, creating a relaxing atmosphere. When fast-paced rock music is playing, assuming the calculated R = 180 BPM, indicating 180 beats per minute, the flashing frequency of the lights will be set to 3 Hz, i.e., 3 flashes per second, to match the fast tempo of the music and enhance the gathering atmosphere. Combining the number of people monitored by the camera in the intelligent sensing module and the light brightness detected by the sensor module, the system calculates the dynamic adjustment of the light brightness for viewing movies in audio-visual entertainment mode as follows:

[0025] L=k1·V+k2·F+k3·R+k4·L screen +k5·N

[0026] Where: L is the brightness of the light, V is the volume, F is the main frequency component, R is the rhythm frequency, L screenis the TV screen brightness, N is the number of people in the room, and k1, k2, k3, k4, and k5 are their respective weights, following the formula k1 + k2 + k3 + k4 + k5 = 1. The weights depend on the influencing factors. When watching a movie in audio-visual mode, the frequency and amplitude of volume fluctuations are relatively small, and their impact on light brightness is generally minimal. Therefore, weight k1 can be set to 0.1. The main frequency components (especially low frequencies) have a more significant impact on lighting, as low frequencies are often associated with action or ambient ambiance, requiring changes in light brightness to enhance immersion. Mid- and high-frequency components have a smaller impact on lighting, but still play a role. Therefore, weight k2 can be set to 0.2. Rhythm frequency has a smaller impact on light adjustment, so weight k3 can be set to 0.1. The brightness of the TV screen and the movie content has a greater impact on the environment, so weight k4 can be set to 0.4. The number of people in the room has a relatively weaker impact on light brightness, so weight k5 can be set to 0.1.

[0027] For example, consider an action movie playing on TV, with the curtains drawn and no additional natural light sources. Four people are in the room, and the volume is set to 70. The movie's audio signal has strong low-frequency components (such as explosions), with a primary frequency component F of 20. Due to the fast tempo and frequent music changes in the action scenes, the rhythm frequency R is 80. Since the scene is dark, the screen brightness is set to 30 Lux. Based on the above calculation formula, the final adjusted light brightness, L, is 34.4 Lux. This indicates that in the current viewing mode, the light brightness is relatively low due to the low screen brightness and the lack of strong volume changes. This brightness is suitable for most viewing environments, ensuring a good visual experience without overly brightening the environment and affecting the viewing experience.

[0028] The sensor module includes multiple sensors, including a light sensor module, a temperature and humidity sensor (both a temperature sensor module and a humidity sensor module), and a PIR (passive infrared) sensor module. This module monitors environmental changes in real time, converting information such as light, temperature, humidity, and occupant status into electrical signals and wirelessly transmitting them to the control module. The control module receives and interprets these signals. The control module analyzes the environmental data and generates instructions, which are sent directly or via an external smart home management system to the corresponding devices, enabling automatic linkage of lighting, curtains, audio, and other devices. In movie viewing mode, the system automatically closes the curtains, lowers the light brightness, and turns on the audio, creating an immersive experience. The system quickly connects to and controls various devices via a wireless network based on pre-set scene modes. The control module connects to various smart devices in the home (such as lights, curtains, audio, and temperature control devices) via the wireless network, processes data received from the sensor modules and user input devices in real time, and issues instructions to each smart device for adjustment. Furthermore, users can issue operational instructions via a smart terminal (such as a mobile phone, tablet, or voice assistant) or directly through the intelligent sensing module. Upon receiving the instructions, the control module transmits them to the relevant devices via the wireless network for adjustment. For example, when a user is in movie viewing mode, the control module sends commands to the smart home system, which then automatically closes the smart curtains, dims the lights, and turns on the speakers, creating an immersive audio-visual experience. All of these operations are managed by the smart home management system, which connects devices via a wireless network to enable them to respond to user needs. The system uses sensor modules to collect environmental data, such as light intensity, temperature and humidity, and human activity, while also recording user behavior and preferences (such as light brightness and curtain position). Based on this collected data, the system trains a model using a convolutional neural network. By continuously optimizing the model, the system can better predict user needs. Each time a user makes a device adjustment, the system records and analyzes these adjustments. Over time, the system automatically optimizes based on data feedback, adjusting for optimal lighting brightness, color temperature, curtain opening, and speaker volume. This gradually improves the accuracy of device linkage, optimizes device linkage logic, and provides intelligent adjustments that better suit user preferences. Users can flexibly select or customize scene modes through smart terminals, mobile apps, or voice commands.

[0029] The storage module includes a user preference and behavior dataset, a scene mode dataset, and an audio and image dataset. This module is responsible for storing various system data, including preset scene mode configurations, user operating habits, ambient audio characteristics, and image information, providing data support for the automated adjustment of the panel lights. The scene mode dataset stores the control logic for different environmental modes, the user preference and behavior dataset records the user's personalized settings in different scenarios, and the audio and image datasets support the system's scene recognition and feature extraction.

[0030] The present invention has the following beneficial effects:

[0031] 1. This product has relatively integrated functions, combining lighting, audio playback, environmental perception and intelligent control into one.

[0032] 2. This product is more intelligent to operate and can support remote control, voice control, and personalized mode settings.

[0033] 3. This product is energy-saving and environmentally friendly, and can achieve energy saving through intelligent perception and adaptive adjustment.

[0034] 4. This product provides a personalized experience: it can automatically optimize based on user habits to meet the needs of multiple scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] See also Figure 1As shown, the present invention is applicable to various indoor environments, such as living rooms, kitchens, and bedrooms. The system uses built-in devices such as a light sensor module 16, a temperature sensor module 17, a humidity sensor module 19, a PIR sensor module 18, and a camera 28 to monitor the ambient light intensity, temperature and humidity changes, and the number of people in the room in real time. It then automatically adjusts the brightness and color temperature of the lights based on the specific room's functions and scene requirements. The system has multiple built-in scene modes, including early wake-up mode, family gathering mode, audio and video entertainment mode, cooking mode, and bedtime reading mode. The kitchen supports cooking mode and family gathering mode. In cooking mode, the system provides high-brightness white light to ensure clear vision during cooking, while in family gathering mode, the light is moderately bright and adjusted to a warm color temperature to create a cozy social atmosphere. The living room supports family gathering mode and audio and video entertainment mode. In family gathering mode, the system adjusts the light brightness to a higher level and enhances the warmth of the light. In audio and video entertainment mode, the system adjusts the light brightness and color temperature based on different audio and video needs to ensure an optimal audiovisual experience. The bedroom supports early wake-up mode and bedtime reading mode. The early wake-up mode provides brighter light to help users wake up gradually, while the bedtime reading mode provides soft light to ensure eye comfort when reading without disturbing sleep.

[0045] The present invention offers several significant advantages: The system uses sensor module 10 to monitor environmental data (such as light intensity, temperature, humidity, and the number of people) in real time, automatically adjusting the brightness and color temperature of the lights according to different room and scene modes. For example, in cooking mode, the kitchen lights are brighter and have a cooler color temperature to improve visibility; in family gathering mode, the lights are adjusted to a warmer color temperature and moderate brightness to create a social atmosphere. Users can select room modes based on their needs using buttons or DIP switches on the housing. When cooking mode is selected in the kitchen, the system automatically adjusts the brightness based on the ambient light and temperature, ensuring sufficient light in the kitchen during cooking. When family gathering mode is selected in the living room, the system adjusts the color temperature and brightness of the lights to create a suitable atmosphere for gatherings. When bedtime reading mode is selected in the bedroom, the system lowers the brightness to warm tones to avoid stimulating sleep. The control module 34 automatically adjusts the lighting settings. Furthermore, within each room mode, the brightness and color temperature parameters of the lights automatically adjust based on environmental changes. Users can also manually adjust the brightness and color temperature of the lights through the controller to meet their individual needs. The system automatically adjusts lighting brightness based on ambient light intensity and indoor temperature and humidity changes, avoiding inefficient energy consumption. For example, during the day, when natural light is strong, the system automatically lowers the brightness of artificial lighting to conserve energy. At night or in low-light conditions, the system increases lighting brightness to ensure adequate illumination. The system also features intelligent learning capabilities, adapting to user habits and preferences. For example, the system records the user's lighting settings in different modes and automatically adjusts to similar settings the next time, enhancing a personalized experience.

[0046] See also Figure 1 As shown, a multimedia-integrated LED smart panel light mainly includes a control module 34, a storage module 15, a sensor module 10, a wireless transmission module 11, a multimedia interaction module 12, a power module 13 and an intelligent sensing module 14.

[0047] See also Figure 1 As shown, the wireless transmission module 11, consisting of a Wi-Fi module 20 and a Bluetooth module 21, is used to wirelessly transmit control commands. The Wi-Fi module 20 is used for remote control, with a control range of 10 meters or more, allowing users to remotely control lamps and other devices via mobile apps. The Bluetooth module 21 is used for short-range device-to-device connectivity, ensuring proper functioning even when the network is unstable. The panel light also connects to external devices, including a smart home management system 55, via the Wi-Fi module 20.

[0048] See also Figure 1As shown, the control module 34 is the core of the system, responsible for receiving and analyzing signals from the sensor modules 10 and the intelligent sensing module 14. It generates control signals based on environmental changes and user instructions and sends them to the multimedia interaction module 12 and other connected smart home devices (such as smart curtains 51, smart humidifiers 52, smart air conditioners 53, etc.) to achieve automatic linkage adjustment. The control module 34 is connected to the storage module 15, wireless transmission module 11, multimedia interaction module 12, and intelligent sensing module 14 to ensure that the devices are optimally configured in different scene modes.

[0049] See also Figure 1 As shown, the sensor module 10 includes a light sensor module 16, a temperature sensor module 17, a PIR sensor module 18, and a humidity sensor module 19. The light sensor module 16 monitors the ambient light intensity in real time, the temperature sensor module 17 and the humidity sensor module 19 are used to monitor changes in temperature and humidity in the room, and the PIR sensor module 18 is used to detect information about human activity in the room. The sensor module 10 monitors light intensity and humidity in real time and transmits the data to the control module 34, which adjusts the brightness and color temperature of the light using a weighted algorithm. When the ambient light is weak, the control module 34 increases the light brightness, and when the ambient light is strong, it automatically lowers the light brightness to adapt to different environmental changes. At the same time, changes in temperature and humidity will also affect the color temperature and brightness of the light. The system automatically adjusts the light settings to improve comfort and energy saving.

[0050] In the bedroom, the system sets two common modes, including early awakening mode and bedtime reading mode. The light brightness calculation formula is as follows:

[0051]

[0052] Where: L is the light brightness, L bkg is the background light intensity, L base is the reference brightness of the room, H is the change value of indoor humidity, T is the change value of indoor temperature, W H is the weight of humidity change value, W T is the weight of the temperature change value. The calculation formula of the temperature change value T is as follows:

[0053] T=T base -T real

[0054] Where: T base is the base temperature of the room, T realis the actual room temperature. When the temperature is too high, the human eye is less sensitive, so the system will appropriately reduce the light brightness. Therefore, the temperature change value should be a negative number to reduce the light brightness. When the temperature is too low, the system needs to increase the light brightness appropriately to compensate for the low temperature.

[0055] The calculation formula of humidity change value H is as follows:

[0056] H=H base -H real

[0057] Among them H base is the reference humidity of the room, H real = is the actual humidity in the room. When humidity is too high, it often creates a dull and oppressive feeling. To alleviate this discomfort, indoor lighting may need to provide brighter light to help improve air clarity and breathability. Therefore, the system will appropriately increase light brightness. Therefore, the humidity change value should be a positive number to increase light brightness. However, when humidity is too low, it can easily cause discomfort to the eyes and skin. In this case, reducing the brightness appropriately can help improve visual comfort and concentration.

[0058] Used to adjust the light brightness through the background light. When the background light is strong, Close to 0, which means less artificial lighting is needed to reduce the light brightness, so take In order to meet the requirement of reducing brightness; when the background light is weak, Greater than 1. In this case, the brightness of the light only needs to meet the baseline brightness of the light, avoiding over-adjustment or overly strong artificial light sources.

[0059] W T , W H The values ​​are weights for temperature and humidity changes, respectively. These are relative values ​​and dynamically adjusted based on environmental changes. In a bedroom, lighting adjustment needs vary depending on the time of day and season. The baseline brightness setting is proportional to the ambient light level, and the light's brightness is always greater than or equal to the ambient light level. Specifically, the goal of bedtime reading mode is to provide a relatively soft lighting environment that meets reading needs but is not too glaring to prevent the user from falling asleep. Therefore, in this mode, the lower the ambient light intensity, the lower the baseline brightness setting, to maintain appropriate reading lighting and promote relaxation before bed. Conversely, the early awakening mode is designed to help users wake up gradually, providing stronger light to stimulate the body's natural circadian rhythm. Therefore, in this mode, the higher the ambient light intensity, the higher the baseline brightness setting, to more effectively help users wake up in the morning. This provides optimal lighting effects at different times and modes, ensuring ideal user comfort in various environments.

[0060] The parameter weight coefficients are shown in Table 1 below:

[0061] Table 1

[0062] time season Baseline brightness Humidity reference value (H) Temperature reference value (T) Temperature and humidity weight daytime Spring and Autumn Period 150 lux 50％ 22℃ <![CDATA[W T =0.05,W H =0.03]]> at night Spring and Autumn Period 75 lux 50％ 22℃ <![CDATA[W T =0.05,W H =0.03]]> daytime summer 200 lux 60％ 25℃ <![CDATA[W T =0.08,W H =0.05]]> at night summer 100 lux 60％ 25℃ <![CDATA[W T =0.08,W H =0.05]]> daytime winter 180 lux 40％ 20℃ <![CDATA[W T =0.07,W H =0.04]]> at night winter 90 lux 40％ 20℃ <![CDATA[W T =0.07,W H =0.04]]>

[0063] For example, on a winter night, the bedroom is in bedtime reading mode. The system detects that the background light intensity in the bedroom is 30 lux through the light sensor module 16, the temperature in the bedroom is 10°C through the temperature sensor module 17, and the humidity is 30% through the humidity sensor module 19. At this time, the system's goal is to provide an environment suitable for reading without affecting sleep. The winter baseline brightness is 90 lux (see Table 1 for winter nighttime), the baseline humidity is 40%, and the baseline temperature is 20°C. According to the calculation, the humidity change value H is 10% and the temperature change value T is 10°C. According to the brightness calculation formula, the final light brightness is 189 lux. In bedtime reading mode, the color temperature is adjusted to warm white light (3000K-3500K), which is suitable for night use and can provide sufficient lighting while avoiding excessively strong cold light that affects the biological clock. It also helps prepare for sleep and enhances the comfort of the bedroom, making it particularly suitable for bedtime reading mode.

[0064] In the living room, the system sets two common modes: family gathering mode and audio-visual entertainment mode. The light brightness calculation formula is as follows:

[0065] L=max((k n p+k v ·V),(k n p+k v ·L base ))

[0066] Where: L is the brightness of the light, k n is the number of people influencing coefficient, p is the number of people in the room monitored by the camera in real time, k v is the brightness influence coefficient, V is the ambient light brightness, L base is the reference brightness. When the background light intensity is higher than the reference brightness, such as in family gathering mode, the daytime light brightness is determined by the background light intensity and the number of people. max((k n p+k v ·V),(k n p+k v ·L base ))Take(k n p+k v V), and for example, when the background light intensity is reduced at night and the family gathering mode is turned on, the light brightness is determined by the number of people and the reference light brightness max((k np+k v ·V),(k n p+k v ·L base ))Take(k n p+k v ·L base ). The number of people influence coefficient k n It is dynamically adjusted based on the number of people in the room. Its value follows a step function. In family gathering mode, the light brightness is increased according to the number of people to enhance the gathering atmosphere. When the number of people in the room is 1-3, k n The value is 0.2. When the number of people is 4-6, k n Increased to 0.4, when the number of people is more than 7, k n Take 0.5. Where p = 100 × number of people.

[0067] In order to avoid the conflict between the two coefficients and ensure the rationality of the final light brightness calculation, the brightness influence coefficient k v is based on the number of people influence coefficient k n The calculation formula is as follows:

[0068] k v =1-k n

[0069] That is, the sum of the two coefficients should be 1 at all times to ensure that their weights are reasonably distributed.

[0070] The base brightness setting is based on ambient light intensity. During the spring and autumn seasons, there is usually ample natural light during the day, and the ambient light intensity can be relatively high. The base brightness should be set to 200 lux to provide comfortable indoor lighting while avoiding excessive brightness. During the summer, ambient light is often stronger during the day, and daylight hours are longer. During this time, natural light intensity is very high, typically reaching 500 to 800 lux, so the need for artificial light is lower. The base brightness should be set to 150 lux to avoid wasting energy and over-illumination. During the winter, the sun is lower during the day, and ambient light intensity is typically weaker, typically only 100 to 300 lux. Even during the day, indoor lighting requires a high level of artificial light. The base brightness should be set to 250 lux to supplement the lack of natural light and ensure bright and comfortable indoor lighting. At night, ambient light is almost zero, and the need for artificial light is greatest. The base brightness can be set to 300 lux to provide sufficient lighting without causing the room to be too dark and disruptive to activities.

[0071] The parameter weight coefficients are shown in Table 2 below:

[0072] Table 2

[0073]

[0074]

[0075] For example, during the summer daytime, in family gathering mode, the system detects through the camera that there are 8 people in the room (p=800). At the same time, the ambient light intensity (V) is 400 lux (indicating that there is strong natural light in the room). n =0.5 (influence coefficient of number of people), k v = 0.5 (brightness influence coefficient). At this point, the system determines the final light brightness to be 600 lux. To ensure that the lighting for family gatherings meets both visual needs and creates a suitable atmosphere, adjust the color temperature to a neutral white light (3500K-4000K). This color temperature is close to natural light in everyday environments, bright but not glaring, and suitable for environments requiring clear illumination. For family gatherings, a more neutral or slightly warmer light can ensure clarity while avoiding being too cold.

[0076] In the kitchen, the system sets two common modes: cooking mode and family gathering mode. The light brightness calculation formula is as follows:

[0077]

[0078] Where: L is the light brightness, L bkg is the background light intensity, L base is the reference brightness of the room, H is the change value of indoor humidity, T is the change value of indoor temperature, W H is the weight of humidity change value, W T is the weight of the temperature change value, where the temperature change value T is calculated as follows:

[0079] T=T base -T real

[0080] Where T base is the base temperature of the room, T real The actual room temperature. During cooking, the temperature rises, and a clear view of the ingredients and work surface is essential. Higher temperatures often correlate with higher kitchen activity, so increasing the light brightness can help facilitate activities like cutting, stir-frying, and baking. Therefore, as the temperature rises, the light brightness increases.

[0081] The calculation formula of humidity change value H is as follows:

[0082] H=H base -H real

[0083] Among them H base is the reference humidity of the room, Hreal The actual humidity in the room. During cooking, humidity in the kitchen typically increases, especially when making soup, steaming, or other high-humidity cooking methods. Water vapor increases the humidity in the air. Humidity changes can also affect lighting adjustments. Excessive humidity can make the air damp and even cause discomfort (such as difficulty breathing and a stuffy atmosphere). To address this feeling, increasing light brightness can compensate for the decreased visual comfort caused by increased humidity. Brighter lighting can help improve the comfort of the environment and reduce the dullness caused by humidity.

[0084] Used to adjust the light brightness through the background light. When the background light is strong, Close to 0, which means less artificial lighting is needed to reduce the light brightness, so take In order to meet the requirement of reducing brightness, when the background light is weak, Greater than 1. In this case, the brightness of the light only needs to meet the baseline brightness of the light, avoiding over-adjustment or overly strong artificial light sources.

[0085] W T , W H The weights of temperature and humidity changes are relative values ​​and are adjusted dynamically according to environmental changes. In the kitchen, the lighting adjustment requirements vary according to different times and seasons.

[0086] The base brightness setting is based on background light intensity, temperature, and humidity. During the daytime in spring and autumn, there's usually ample natural light, resulting in higher ambient light intensity, while humidity and temperature fluctuations are relatively small. Therefore, the base brightness should be set to 200 lux. During the daytime in summer, ambient light is typically stronger, and daylight hours are longer. However, temperature and humidity fluctuations are relatively high, so the base brightness should be set to 260 lux. During the daytime in winter, the sun is lower, ambient light intensity is typically weaker, and temperature and humidity fluctuations are relatively high. Therefore, the base brightness should be set to 260 lux. At night in all seasons, ambient light is almost zero, and the need for artificial lighting is greatest. The base brightness can be set to 280 lux to provide sufficient illumination to prevent the room from being too dark and affecting activities.

[0087] The parameter weight coefficients are shown in Table 3 below:

[0088] Table 3

[0089]

[0090]

[0091] For example, on a summer evening, with the kitchen in cooking mode, the system detects a background light intensity of 100 lux via light sensor module 16, a temperature of 28°C via temperature sensor module 17, and a humidity of 68% via humidity sensor module 19. The system's goal is to provide sufficient artificial lighting to ensure clear visibility of kitchen operations and maintain a comfortable cooking environment. The baseline brightness for summer nights is 280 lux, and the baseline temperature and humidity are 22°C and 60%, respectively. The calculated temperature change is 6°C and the humidity change is 8%, resulting in a final brightness of 532 lux. In cooking mode, the color temperature is adjusted to a cooler tone (5000K), which helps reduce the sensation of heat and provides clearer lighting while maintaining a comfortable visual experience. Cooler lighting improves visual clarity and helps users better operate the kitchen, making it particularly suitable for cooking.

[0092] This method enables the lighting fixtures to adapt to the scene environment, improving the convenience and comfort of living. Figure 1 and Figure 4 As shown, the intelligent sensing module 14 uses camera 28 to capture an RGB image of the current environment. The smoothing module 35 within the control module 34 applies a Gaussian blur filter to smooth the image before inputting it into the convolutional neural network (CNN) within the control module 34. The CNN extracts image features layer by layer through multiple convolutional layers, with feature processing module 36 then classifying information such as furniture, decorations, and spatial layout. The recognition module 37 then identifies the room type. Based on the CNN analysis results, the system determines the current room type. Room types are categorized as living room, bedroom, kitchen, and other types. Based on the room type, the system issues instructions to the multimedia interaction module 12. The multimedia interaction module 12 adjusts the lighting parameters for brightness, color temperature, color, and lighting scene by dimming the main LED light 23 and / or the side LED lights 24. If the room type is a bedroom, the system adjusts the light color temperature to 2700K-3500K, a warm white color. Warm white light is soothing and suitable for bedtime and relaxation. Users can adjust the brightness to a lower setting to facilitate sleep. When the room type is a living room, the system adjusts the light color temperature to 4000k-5000k, a neutral white. Neutral white light is suitable for daily activities and can adapt to various scenarios such as reading and gatherings. Users can adjust the brightness to suit different activities. When the room type is a kitchen, the system adjusts the light color temperature to 5000k-6500k, a cool white. Cool white light enhances illumination and is suitable for delicate kitchen operations. Users can adjust the color temperature and brightness to suit different cooking or cleaning needs. The parameter index is shown in Table 4:

[0093] Table 4

[0094]

[0095]

[0096] Based on the system's automatic settings, users can also manually adjust the brightness and color temperature of the lights through smart terminals or voice commands, greatly meeting users' personalized lighting needs.

[0097] See also Figure 1 As shown, when the multimedia interactive module 12 is in viewing mode, the main LED light 23 is automatically turned off, and the LED side light 24 projects soft light onto the TV wall. The microphone 29 in the intelligent sensing module 14 captures the audio signal in real time, and sends a command system to the multimedia interactive module 12 through the control module 34 to adjust the brightness and color temperature of the light, thereby achieving synchronous sound and light control. The PIR sensor module 18 in the sensor module 10 monitors the human activity status in the room in real time. The system decides whether to turn the device on or off based on the detection results, thereby improving usage efficiency. User preferences are recorded through an intelligent learning algorithm, stored in the storage module 15, and automatically optimized in similar scenarios. The real-time feedback mechanism allows users to adjust the effect through mobile applications or voice commands, further enhancing the personalized experience.

[0098] See also Figure 2 The figure shows the external structure of a multimedia-integrated LED smart panel light, which mainly includes LED side lights 1, camera 2, LED main light 3, an external sensor module 4 (here, a visible sensor such as a PIR), and a side cover 5. The device achieves intelligent lighting adjustment and multimedia interactive functions through the coordinated action of sensors, cameras, and control modules. The LED side lights 1 are installed at the edge of the device and are responsible for providing soft ambient lighting in specific modes. In movie viewing mode, for example, the side lights can create ambient light, reducing direct stimulation to the eyes from the main light while enhancing visual comfort. Camera 2 is installed in the middle of the side of the device to capture environmental images in real time. Through functions such as face detection and environmental recognition, it obtains information such as the number of people in the room, user status, and room layout, providing data support for subsequent lighting mode selection and multimedia control. The LED main light 3 is the main lighting source and can automatically adjust brightness and color temperature according to environmental requirements and user selection. It can provide lighting effects with different color temperatures, such as bright white light and warm yellow light, to suit various scene modes such as waking up early, reading, and movie viewing and entertainment. Please refer to Figure 2The external sensors shown, the sensor module 4 includes, for example, a light sensor, a temperature and humidity sensor, and a PIR (passive infrared) sensor. The light sensor is used to detect the ambient light level, the temperature and humidity sensor detects the current temperature and humidity, and the PIR sensor detects the activity information of people in the room. The sensor module converts the monitored environmental data into an electrical signal and transmits it to the control module to provide a basis for automatic adjustment of the light. The side cover 5 plays a role of protection and shielding, while softening the light of the lamp to make the light softer and more uniform, thereby improving the user's visual experience. The smart panel light is designed with a modular structure and is easy to install and maintain. Users can install it on the ceiling or wall of the room and use the control panel or mobile application for daily operation and maintenance. The modular design allows sensors, lamps, cameras and other parts to be replaced or upgraded separately, extending the service life of the equipment.

[0099] See also Figure 3 Figure 2 shows the internal structure of a multimedia-integrated LED smart panel light, primarily comprising key components such as a control module 34, a speaker 22, a reflector 8, and a diffuser 9. The control module 34 is the core component of the system, responsible for receiving data from the sensor module 10 and the intelligent sensing module 14, including signals from light, temperature and humidity, and the PIR sensor, and generating corresponding control instructions based on these signals. The control module 34 sends instructions to the lighting control unit, the speaker control unit, and other associated devices (such as curtains and air conditioners), enabling automatic linkage of multiple devices. The speaker 22 is an embedded speaker module for providing background music or ambient sound effects. The speaker 22 receives audio signal instructions from the control module 34 and can automatically adjust sound parameters such as volume and frequency using digital signal processing technology. The output volume of the speaker 22 is adjusted synchronously with the light brightness, matching the light to the rhythm of the music and enhancing the user's audio-visual experience. The reflector 8 is installed inside the lamp body, above the LED light source. The reflector 8 is used to reflect light emitted by the LED light source onto the diffuser 9, evenly dispersing the light across the diffuser 9. Reflector 8 is made of highly reflective aluminum alloy or specially coated plastic, effectively improving light utilization and ensuring even light distribution across the illuminated area, thereby preventing glare. Diffuser 9, located at the outermost layer of the lamp, evenly distributes light reflected from reflector 8, softening the illumination. Made of acrylic, it offers high light transmittance and excellent diffusion properties, which evenly diffuses light, eliminating hotspots and improving lighting quality, creating a softer lighting environment.

[0100] See also Figure 5The figure illustrates the automatic mode switching function of the present invention. It dynamically adjusts lighting effects (mode comprehensive determination 44, mode change 45) based on the current time (time condition determination 40), user posture (user status determination 41), room background light intensity (light intensity condition determination 42), and room ambient sound volume (volume condition determination 43), providing a personalized immersive experience. The system has multiple preset modes, including early awakening mode, lunch break mode, TV watching mode, bedtime reading mode, music listening mode, and family gathering mode. The system utilizes the camera 28 within the intelligent sensing module 14, the light sensor module 16 within the sensor module 10, and the microphone 29 within the intelligent sensing module 14. The camera 28 captures an image of the user in the room, the light sensor module 16 detects changes in the room's ambient light intensity, and the microphone 29 detects the room's ambient sound. All data is collected and transmitted to the control module 34. First, when the default trigger time for each mode is reached, the control module 34 invokes the camera 28. The camera 28 captures real-time image data of the user, applies image processing and invokes a skeleton algorithm to recognize the user's posture. If the user's posture conditions for the mode are met, the next step is determined. The light sensor module 16 is called to detect the change of the ambient light intensity in the room. If the light change condition of the mode is met, the next step of determination is performed. The microphone 29 is called to detect the ambient sound in the room. If the ambient sound condition of the mode is met, the mode is automatically switched to the mode.

[0101] The following describes the early awakening mode in detail: First, the control module 34 obtains the current time (typically between 6:00 and 8:00 AM) and retrieves the user's daily early awakening time period from the storage module 15 to check whether it matches the current time (time condition determination 40). If the time period requirement is met, the next determination is performed; if not, the subsequent determination process is suspended. After the time determination is met, the camera 28 is called to acquire real-time image data of the user. Image processing and a skeleton algorithm are applied to perform user posture recognition. When the user transitions from a lying position to a sitting position (user state determination 41), the posture determination condition is met and the next determination process is performed. If the user remains in a lying position, the posture determination condition for this mode is not met, and the subsequent determination process is suspended. After the posture determination condition is met, the light sensor module 16 is called. The light sensor module 16 collects the room background ambient light intensity at a certain frequency (e.g., 10 times per second). In the morning, the room light changes from dark to bright, and the light intensity gradually increases (e.g., from 50 lux to 150 lux) (light intensity condition determination 42). If the light determination condition is met, the next determination process is performed. The microphone 29 is called, and the microphone 29 detects the ambient background sound in the room (volume condition determination 43). For example, the ambient background sound is the sound of a mobile phone alarm. If all the determination conditions are met, the early waking mode is triggered (mode comprehensive determination 44, change mode 45), and the control module 34 sends a command to the LED main light 23 to gradually increase the light brightness to simulate natural light. At this time, the storage module 15 is checked to see if there is a historical preference for playing music. If so, the control module 34 sends a command to the speaker 22 to start playing soft music to help the user gradually wake up. After the user gets up, the user is consulted for satisfaction feedback through the smart terminal to collect preference data. The system records configurations such as time, user posture, background light intensity, and room ambient sound volume, and optimizes the triggering conditions and environmental settings of the future early waking mode based on user feedback. The trained model is stored in the storage module 15 for later call by the control module 34.

[0102] The following is a detailed introduction to the bedtime reading mode: First, the control module 34 obtains the current time (usually between 8 and 11 p.m.) and calls the user's bedtime reading time period in the storage module 15 to check whether it is consistent with the current time (time condition determination 40). If the time period requirement is met, the next determination is performed; if not, the next determination process is suspended. After the time determination is met, the camera 28 is called to obtain the user's real-time image data, and image processing and a skeleton algorithm are called to perform user posture recognition. When the user is identified as being in a head-down posture for a long time (user state determination 41), the posture determination condition is met, and the next determination process is performed. If the user is not identified as being in a head-down reading state, the posture determination condition in this mode is not met, and the next determination process is suspended. After the posture determination conditions are met, the light sensor module 16 is called, and the light sensor module 16 collects the background ambient light intensity of the room at a certain frequency (for example, 10 times per second). The brightness at night is about 100 lux (light intensity condition determination 42. If the light determination conditions are met, go to the next step of determination. The microphone 29 is called, and the microphone 29 detects the ambient background sound in the room (such as when it is lower than 40dB) (volume condition determination 43). If all the determination conditions are met, the bedtime reading mode is triggered (mode comprehensive determination 44, change mode 45). The control module 34 sends a command to the LED main light 23 to adjust the light color temperature to a range suitable for reading (4000K to 5000K neutral light). The system checks the storage module 15 to see if there is a historical preference for playing music. If so, the control module 34 sends a command to the speaker 22 to start playing soft music to enhance the atmosphere of concentration. If the system is connected to other smart home devices (such as curtains), it sends a command to the smart curtains 51 to draw the curtains to reduce external light interference and optimize the reading environment. After the user finishes reading, the system consults the user for satisfaction feedback through the smart terminal and collects preference data. The system records configurations such as time, user posture, background light intensity, and room ambient sound volume, and optimizes the trigger conditions and environmental settings of the future bedtime reading mode based on user feedback. The trained model is stored in the storage module 15 for later call by the control module 34.

A user 46 can interact with the smart home management system 55 or directly with the LED smart panel light 50 via a smart terminal such as a mobile phone 47, PAD 48, or smart wristband 49, achieving centralized control and coordinated adjustment of various smart devices in the home environment.
