Description

[0001] This application is a divisional application of the invention patent application filed on January 4, 2024, with the invention name “A healthy and intelligent lighting method and system for a study room” and application number 202410012723.7. Technical Field

[0002] The present invention relates to the field of intelligent lighting, and in particular to a healthy lighting method and system for a study room based on dynamic adjustment of lighting parameters. Background Art

[0003] In recent years, the number of students taking postgraduate and civil service examinations has increased year by year, and as a result, the number of study rooms has also increased. However, there are currently some common problems with the lighting in study rooms.

[0004] In some study rooms, lighting fixtures may be unevenly arranged and uniform, resulting in weak lighting in some areas and excessive brightness in others. This lack of differentiated and appropriate lighting for different activities can impact learners' comfort and visual experience in different areas or settings. Excessive light can cause glare and visual fatigue, impacting learners' attention and concentration, and causing discomfort for those taking a break. Too little light, on the other hand, can dim the learning environment, hindering learners' ability to read and perceive information. Furthermore, study room lighting settings are not properly tailored to specific scenarios. Different color temperature and brightness settings are required for different study scenarios, but inappropriate color temperature and brightness settings can affect learners' comfort and concentration. The lack of adjustable color temperature and brightness options also limits learners' personalized needs. Furthermore, some study rooms have the problem of lights remaining on for extended periods, maintaining high brightness even when unoccupied. This energy waste is not only environmentally unfriendly but also increases energy costs.

[0063] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present invention by illustrating examples of the present invention.

[0064] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0065] In some study rooms, lighting fixtures may be unevenly arranged and uniform, resulting in weak lighting in some areas and excessive brightness in others. This lack of differentiated and appropriate lighting for different activities can impact learners' comfort and visual experience in different areas or settings. Excessive light can cause glare and visual fatigue, impacting learners' attention and concentration, and causing discomfort for those taking a break. Too little light, on the other hand, can dim the learning environment, hindering learners' ability to read and perceive information. Furthermore, study room lighting settings are not properly tailored to specific scenarios. Different color temperature and brightness settings are required for different study scenarios, but inappropriate color temperature and brightness settings can affect learners' comfort and concentration. The lack of adjustable color temperature and brightness options also limits learners' personalized needs. Furthermore, some study rooms have the problem of lights remaining on for extended periods, maintaining high brightness even when unoccupied. This energy waste is not only environmentally unfriendly but also increases energy costs.

[0066] Example 1

[0067] To solve the above problem, see Figure 1 The embodiment of the present invention provides a healthy lighting method for a study room based on dynamic adjustment of illumination parameters, the method comprising:

[0068] S1. Obtaining activity scenes in the study room, wherein the activity scenes include study scenes and rest scenes;

[0069] Specifically, this step distinguishes the activity scenes of the study room. In some cities, paid study rooms not only have study areas but also rest areas. When learners feel tired after studying for a long time, they can rest in the rest area. Providing different lighting modules and light environments for different activity scenes can help learners learn better or rest better. In one embodiment, the distinction of the activity scenes of the study room can be obtained through the layout information of the study room. The study room usually has clear area divisions, such as study areas, rest areas, etc. By understanding the layout of these fixed areas, the main purpose of a certain area can be determined, thereby distinguishing the activity scenes of the study room;

[0070] In another embodiment, the activity scene distinction of the study room can also be obtained through video surveillance analysis. High-resolution cameras are installed at key locations in the study room to capture the activities in the study room. The video surveillance system continuously captures image data in the study room. Based on machine learning algorithms, the postures and activities of people in the study room can be analyzed. For example, the postures of sitting for study and lying down for rest can be distinguished. A posture estimation algorithm such as OpenPose can be used to analyze key points of the human body to identify different postures and activity states. Classification is performed based on the postures and activity states, thereby distinguishing scenes in different areas.

[0071] S2. Performing intelligent calculation on the lighting mode according to the activity scene to obtain light environment control parameters, wherein the light environment control parameters include color temperature parameters and brightness parameters;

[0072] Specifically, in learning scenarios, appropriate lighting modes can provide appropriate light brightness and color temperature, which is conducive to concentration, improving attention span and work efficiency. For example, brighter white light can increase alertness and concentration, which is conducive to handling complex learning tasks; while soft yellow light helps to relax the body and mind, improve concentration, and is suitable for reading and thinking. In rest scenarios, appropriate lighting modes can create a comfortable atmosphere, promote physical and mental relaxation and rest recovery. For example, soft warm-toned lighting can relieve stress, reduce eye fatigue, and help adjust the biological clock to improve the quality of rest. Intelligent computing and light environment control can be personalized according to individual needs and preferences to meet the special requirements of different groups of people and provide a more comfortable and suitable learning and rest environment.

[0073] As an optional embodiment of the present invention, see Figure 2 The step of performing intelligent calculation on the lighting mode according to the activity scene to obtain the light environment control parameters includes:

[0074] S21, obtaining the area where the learning scene is located and the area where the rest scene is located;

[0075] Based on the activity scenes in the study room obtained in step S1, the study room can be divided into a study area and a rest area. Accurately identifying these areas allows the lighting system to adopt specific lighting strategies for each scene, thereby improving space utilization efficiency and creating the best environment for each activity.

[0076] S22. Setting light environment control parameters for the area where the learning scene is located according to the first color temperature value and the first brightness value;

[0077] After confirming the learning area, the system sets the light environment control parameters for the learning area based on the first color temperature and brightness values. A high color temperature and higher brightness lighting mode can be used for the learning area to meet the learner's lighting needs and improve their concentration. Learning areas generally require higher color temperature and brightness to promote concentration and clear visual perception.

[0078] S23, setting the light environment control parameters of the area where the rest scene is located according to the second color temperature value and the second brightness value;

[0079] After confirming the rest area, the system sets the light environment control parameters of the learning scene area according to the first color temperature value and the second brightness value. A low color temperature and low brightness lighting mode is used for the rest area to provide a comfortable light environment for people in the rest area. Secondly, the lighting in the rest area can also be adjusted independently according to different needs or environments. Therefore, in this embodiment, the first color temperature value is greater than the second color temperature value, and the first brightness value is greater than the second brightness value;

[0080] This series of steps intelligently adjusts the lighting environment in different areas of the study room, not only improving lighting efficiency but also creating an environment conducive to learning and rest. This approach not only protects eyesight and improves learning efficiency, but also takes into account the psychological and physical health needs of users.

[0081] Specifically, the first brightness value, the second brightness value, the first color temperature value, and the second color temperature value can be obtained by setting different initial brightness parameters and initial color temperature parameters for each time period for the learning scene and the rest scene, and combining the current ambient light parameters to obtain the final first brightness value, the second brightness value, the first color temperature value, and the second color temperature value;

[0082] By way of example and not limitation, the preset values ​​for each time period are as follows:

[0083] Morning: First brightness value preset value: 500-700l x; First color temperature value preset value: 5500-6500K; Second brightness value preset value: 300-500l x; Second color temperature value preset value: 4000-5500K;

[0084] Noon: First brightness value preset value: 600-800l x; First color temperature value preset value: 5000-6000K; Second brightness value preset value: 250-400l x; Second color temperature value preset value: 3500-5000K;

[0085] Evening: First brightness value preset value: 300-500l x; First color temperature value preset value: 5000-6000K; Second brightness value preset value: 250-400l x; Second color temperature value preset value: 3500-5000K;

[0086] The system selects preset values ​​corresponding to the first brightness value, the second brightness value, the first color temperature value, and the second color temperature value based on the current time. The system uses a light sensor to monitor ambient light data in real time and dynamically adjusts the brightness and color temperature of the indoor lighting based on the ambient light data. If the external light is strong, the indoor lighting brightness is reduced to avoid unnecessary energy consumption and excessive lighting. If the external light is dim, the indoor lighting brightness is increased to ensure sufficient lighting. The color temperature is adjusted to complement the color characteristics of natural light, for example, using warmer light on cloudy days to balance the blue tones of the external light.

[0087] As an optional embodiment of the present invention, when the activity scene is a learning scene, the step of performing intelligent calculation on the lighting mode according to the activity scene to obtain the light environment control parameters further includes:

[0088] S221, determining whether the current learner's learning scenario is reading a book or using an electronic device;

[0089] Specifically, in this embodiment, the learning area in the learning scene includes a plurality of independent study positions, and each study position is equipped with an independent lighting module to provide learning lighting for each study position. By intelligently identifying and calculating the learning scene, it is determined whether the learner is reading a paper book or studying through an electronic device when studying at the study position. The electronic device includes a mobile phone, a laptop computer, a tablet computer, etc. The current learner's learning scene can be determined to be reading a book or using an electronic device by using a camera to capture an image of the learning area, and using computer vision technology to analyze and identify the objects in front of the learner. The algorithm can be trained to distinguish between electronic devices (such as laptops, tablet computers) and paper books, or to analyze the learner's usage behavior patterns and observe the learner's gestures and movements. The actions when reading a paper book (such as turning pages) are different from the actions when using an electronic device (such as tapping the keyboard or touching the screen);

[0090] In one embodiment, determining whether the current learner's learning scenario is reading a book or using an electronic device can be achieved by detecting specific spectral characteristics of the electronic screen through an ambient light sensor. Electronic screens, especially LCD or LED screens, usually emit light of a specific wavelength, which can be captured by a specific sensor. When the specific spectral characteristics are captured, it can be determined that the current learner's learning scenario is using an electronic device, otherwise the previous learner's learning scenario is reading a book.

[0091] S222, when the learner is reading a book, set the color temperature parameter of the light environment control parameter of the learning scene area to white color temperature and reduce the first brightness value;.

[0092] When a learner is reading a book, the color temperature of the light environment control parameters for the learning area is set to white. White color temperature (i.e., white light) typically features high brightness and a full spectrum, providing high contrast, making text clearer and easier to read. This is crucial for reading, as clear text helps readers better understand the content and reduces the possibility of misunderstandings. Brighter white light stimulates the brain and increases alertness, helping to improve concentration and attention span during reading. This is particularly beneficial for complex or focused learning tasks, allowing readers to better immerse themselves in the book and avoid external distractions. White light is believed to regulate the human body clock, enhance alertness and concentration. Maintaining alertness, especially when reading, can promote thinking and comprehension, contributing to deeper and more quality learning. However, excessively bright white light may cause some eye strain. Therefore, when reading, moderate lighting brightness and avoid direct exposure to excessive light can reduce eye discomfort and fatigue, allowing learners to focus and read for longer periods of time.

[0093] S223: When the learner is using an electronic device, the color temperature parameter of the light environment control parameter of the area where the learning scene is located is set to yellow light color temperature and the first brightness value is increased.

[0094] When using electronic devices, setting the color temperature parameter for light environment control to yellow can reduce exposure to blue light, alleviating eye fatigue and visual strain. Electronic devices (such as smartphones, tablets, and computer monitors) typically emit a high amount of blue light. Blue light, with its high energy and short wavelength, easily scatters and penetrates the eyes, causing optical damage and visual fatigue. Blue light is the primary light source in electronic devices, and prolonged exposure to it can easily lead to eye fatigue, dryness, and visual discomfort. Yellow light, with its lower blue content, helps alleviate eye strain. Therefore, using yellow light can effectively suppress the effects of blue light, reducing blue light irritation to the eyes, and alleviating visual fatigue and discomfort. Compared to blue or white light, yellow light has a lower color temperature, creating a softer, warmer environment. This light reduces visual strain, glare, and reflections, making the visual experience more comfortable and natural. This makes it easier for learners to use electronic devices. Intelligent control based on the learner's context can provide a personalized learning environment. Adjusting the lighting mode to suit different learning scenarios can meet learners' needs, improving learning outcomes and comfort. This personalized lighting environment setting can help learners focus better on learning and improve learning efficiency.

[0095] Secondly, to address the issue of blue light produced by electronic devices causing eye fatigue, students can choose soft and even lighting to avoid strong light and excessive shadow contrast. Providing even and stable light helps reduce eye fatigue. According to individual needs and the lighting environment, appropriately adjust the brightness of the light around electronic devices to avoid excessively bright or dim light stimulation to reduce eye fatigue.

[0096] As an optional embodiment of the present invention, when the learner is using the electronic device, after setting the color temperature parameter of the light environment control parameter of the learning scene area to yellow light color temperature and increasing the first brightness value, further comprising:

[0097] S224, monitoring the continuous duration of the learner's use of the electronic device, and comparing the continuous duration with a preset duration threshold;

[0098] In this embodiment, regardless of the type of lighting used, staring at the screen of an electronic device for a long time will cause eye fatigue. Therefore, it is very important to rest your eyes regularly, perform eye relaxation and eye exercises, which can help relieve eye discomfort and fatigue. Therefore, in this embodiment, when a learner is identified as using an electronic device to study in a self-study position, the usage time of the learner's electronic device is synchronously detected and calculated, and the usage time is compared with the preset time threshold, with reference to the advice of ophthalmologists and ergonomics. It is generally recommended to rest for at least 20 seconds after using an electronic device for every 20 to 30 minutes, and users of different age groups have different lighting needs. For example, children and teenagers may need more frequent breaks, and different preset time thresholds can be provided for different age groups, or users can be allowed to adjust them according to their personal needs. In this way, the intelligent lighting system can remind users to take regular breaks when using electronic devices, thereby helping to reduce eye fatigue and protect vision health.

[0099] S225: If the continuous duration is greater than or equal to the preset duration threshold, control the light to change to remind the learner to take a break in time;

[0100] The lighting changes include light flickering, color change or brightness change.

[0101] When a learner is identified as using an electronic device to study at a self-study position, the system will synchronously detect and calculate the usage time of the learner's electronic device. When the learner's usage time reaches the preset usage time, the system will remind the learner to take a break in time and look into the distance to relieve eye fatigue by changing the light. After the light changes to remind, the learner's usage time of the electronic device is reset. When the reset time reaches the preset usage time again, the system will remind the learner again by changing the light. If the learner leaves the self-study position within the preset usage time or switches to reading a book, the usage time of the electronic device will be stopped. When the learner uses the electronic device again, the usage time will be reset.

[0102] In another embodiment, when a learner alternates between using an electronic device and a book to study, the duration of the learner's interruption of the electronic device needs to be monitored. If the duration of the interruption is within a certain preset interruption range, the timing of the electronic device's usage time will not be stopped. For example, if the preset interruption range is 5 minutes, when it is detected that the learner has interrupted the use of the electronic device, the duration of the interruption is counted. If the interruption is less than 5 minutes, the interruption will continue to be counted in the electronic device's usage time. When the usage time of the electronic device reaches the preset usage time, the light changes to remind the learner to take a break in time.

[0103] In another embodiment, based on the above embodiment, when a learner alternates between using an electronic device and reading a book to study, if the learner is detected reading a book, the light is switched to white and the brightness is appropriately reduced; if the learner is detected using an electronic device again, the light is switched to yellow and the brightness is appropriately increased. Furthermore, the switching of lights should be done in a gradual transition to prevent drastic changes in light from disrupting the learner's attention.

[0104] As an optional embodiment of the present invention, when the learner is using the electronic device, after setting the color temperature parameter of the light environment control parameter of the learning scene area to yellow light color temperature and increasing the first brightness value, further comprising:

[0105] S226. Acquire location information of a display screen of the electronic device;

[0106] Specifically, when illumination light shines directly on the display screen, light reflection from the display screen surface is relatively reduced. Some incident light is absorbed or scattered by the display screen, rather than fully reflected back to the eye. This reduces the bounce of reflected light and minimizes the interference caused by reflected light entering the eye. Furthermore, direct illumination on the display screen can reduce glare, a visual sensation caused by intense light stimulation that can be irritating and uncomfortable to the eyes. When illumination light shines directly on the display screen, some light is absorbed or scattered by the display screen, reducing the intensity of light directly incident on the eye. This reduces glare and creates a more comfortable lighting environment for the eye.

[0107] Therefore, this step first obtains the position information of the display screen of the electronic device. The position information can be obtained by using a camera to capture an image of the study area, and using an image recognition algorithm to identify and locate the screen of the electronic device, accurately obtaining the position information of the screen of the electronic device, thereby effectively adjusting the lighting conditions to improve the user's visual experience and reduce eye fatigue.

[0108] S227: Control the lighting area of ​​the light source to overlap with the display screen according to the position information.

[0109] Specifically, after confirming the position of the electronic device screen, adjust the light source so that the illuminated area always follows the area where the display screen is located, and reduce the brightness of other areas where the display screen is located. This can reduce glare and reflections, improve the visual experience when viewing the screen, and reduce eye fatigue. On the other hand, overlapping the lighting area with the area where the display screen is located can evenly distribute the light in the working area, avoiding overly bright or dark areas. This helps to create a more comfortable and coordinated lighting environment and reduce the possibility of visual discomfort. Maintaining visual field continuity: When the lighting area overlaps with the area where the display screen is located, the visual field transition can be more coherent. This is especially important for people who use electronic devices for work or study for a long time. It can reduce the pressure on the eyes to adapt to switching between different brightness areas and better maintain concentration.

[0110] In another embodiment, the lighting angle is adjusted in real time by tracking the position and tilt of the display screen, so that the lighting forms an angle of less than 90 degrees with the display screen. Generally, the angle is preferably between 30 and 45 degrees. Learners can also adjust the angle range based on the display screen type, ambient lighting conditions, and personal visual experience.

[0111] In another embodiment, based on the above embodiment, the brightness and color temperature of the current display screen can be identified, and the brightness and color temperature of the lighting can be adjusted based on the brightness and color temperature information of the current display screen. The adjustment method is as follows: by identifying the brightness level of the display screen, the brightness of the surrounding lighting can be adjusted to match it. For example, if the brightness of the display screen is high, the brightness of the surrounding lighting can be reduced to avoid excessive contrast that causes eye fatigue. Conversely, if the brightness of the display screen is low, the brightness of the surrounding lighting can be increased to ensure sufficient brightness. The color temperature of the display screen can also affect eye fatigue. Generally speaking, higher color temperatures (blue light) increase the risk of visual fatigue. By identifying the color temperature of the display screen, the color temperature of other lighting can be adjusted to compensate. For example, lighting with a lower color temperature (such as yellow or warm light) can be selected to balance the color temperature of the display screen and reduce the irritation of blue light to the eyes. When the blue light on the screen is strong, the brightness of the yellow or warm light can be increased to correct the color temperature of the display screen.

[0112] S3. Control the light source of the study room for lighting according to the light environment control parameters.

[0113] Specifically, based on the light environment control parameters obtained in the aforementioned steps, the light source in the study room can be controlled to provide targeted lighting for different areas of the study room, thereby providing a comfortable and efficient learning environment. This system also helps improve energy efficiency and reduce unnecessary energy consumption.

[0114] As an optional embodiment of the present invention, see Figure 3 , controlling the light source of the study room to illuminate according to the light environment control parameters includes:

[0115] S31, obtaining reservation information and human body sensing information corresponding to each study position in the study room, wherein the reservation information includes reserved study position information and reservation duration information;

[0116] Specifically, study room locations are reserved in advance through the system, and specific study locations are selected based on learners' preferences. Therefore, reservation information can be obtained through an online reservation system. Reservation information includes the reservation location and duration. Human sensing information is obtained through sensors installed in the study room (such as infrared sensors and motion sensors) to detect whether there is someone at each location;

[0117] S32: When reservation information exists at a self-study position, determining whether there is a learner at the corresponding self-study position based on the human body sensing information;

[0118] When there is reservation information at a self-study position and the reservation time period has arrived, it is determined whether there is a learner at the corresponding self-study position according to the human body sensing information;

[0119] S33: If there is a learner, control the light source to illuminate the self-study position according to the light environment control parameters;

[0120] If it is determined that there is a learner at the self-study position, the system controls the lighting of the corresponding position according to the light environment control parameters (such as brightness and color temperature);

[0121] S34. If there is no learner, control the lighting of the self-study position to switch to low power consumption mode or turn it off.

[0122] If a reserved study space is empty, the system switches the lighting in that space to low-power mode or turns it off completely. The intelligent control system automatically dims or turns off the lighting in unoccupied study spaces. In low-power mode, the lights are kept at a very low brightness, saving energy while making it easier for students to find their reserved space. This solution significantly improves the energy efficiency of study rooms while providing students with a personalized, comfortable learning environment. By combining reservation information with occupancy sensing technology, the system manages lighting resources more intelligently and efficiently.

[0123] As an optional embodiment of the present invention, the step of controlling the lighting of the self-study position to switch to a low power consumption mode or turn off if there is no learner includes:

[0124] S341: When the learner leaves the self-study location, it is determined whether the self-study location is still within the reservation time based on the reservation duration information;

[0125] Specifically, to provide a more intelligent method for preventing lights from being constantly on, the situation in which a learner leaves a study area is distinguished. A learner may leave a study area for a short time, for a long time, or to leave the study room after finishing their studies. In this step, human body sensing information is used to determine when a learner leaves a study area, and the reservation duration information is used to determine whether the study area is still within the reservation time.

[0126] S342: If the self-study location is within the reservation time, obtain the learner's departure time;

[0127] S343: When the absence time is longer than a preset absence time, controlling the lighting of the study area to switch to a low power consumption mode;

[0128] S344: When the absence time is less than the preset absence time, the lighting of the study area is maintained unchanged;

[0129] S345: If the self-study location exceeds the reservation time, control the lighting of the self-study location to be turned off.

[0130] Specifically, if a student is away for a short period of time, a preset absence time can be set—for example, 10 minutes—and the study area is within the reserved time period. If the student is away for more than 10 minutes, the lighting mode remains unchanged. If the student is away for more than 10 minutes, the lighting switches to low-power mode, dimming the brightness and color temperature to alert other students of the student's temporary absence and reducing power consumption to prevent energy waste. Once the reserved time period has expired, the lighting automatically and slowly dims, reminding the student to renew their appointment or reminding them that their appointment is approaching. If the student does not renew their appointment after the timeout, the lighting is turned off. If a student leaves the study room before their scheduled time, they can end their study session early using the app or mini-program, automatically turning off the lighting. If the student does not actively end their study session and their absence exceeds 10 minutes, the lighting switches to low-power mode and then automatically turns off after the reserved time period has expired.

[0131] As an optional embodiment of the present invention, see Figure 4 After the step of controlling the light source of the study room to illuminate according to the light environment control parameters, the method further includes:

[0132] S4. Generate a self-study time schedule based on the reservation duration information and the preset concentration time range, wherein the self-study time schedule includes a plurality of alternating self-study time periods and rest time periods;

[0133] Specifically, this step first generates a number of alternating self-study time periods and rest time periods based on the appointment duration information and preset concentration time range of each learner. The preset concentration time range is set based on human physiology. Regarding the concentration time and rest time, you can refer to some psychology and ergonomics research. A commonly used method is the Pomodoro Technique, but the specific time can be adjusted according to actual conditions and personal needs. The concentration time is usually recommended to be between 25 and 50 minutes. Shorter cycles (such as 25 minutes) are more suitable for high-intensity learning tasks, while longer cycles (such as 50 minutes) are suitable for tasks that require longer sustained attention. The Pomodoro Technique recommends 25 minutes of work time, followed by a 5-minute break. The short break time is recommended to be 5-10 minutes, which is enough for the brain to relax and recover. After every few study cycles, a longer break, such as 15-30 minutes, can be arranged. Based on the appointment duration and the above time range, a schedule with alternating study and rest periods can be generated. For example, if a learner has booked a 3-hour session, it can be arranged into four 25-minute study periods, each followed by a short 5-minute break, and a longer break to end the self-study period. By taking regular breaks, fatigue can be avoided, thereby maintaining high efficiency and concentration during the study time.

[0134] S5. During the self-study period, controlling the light source to illuminate the self-study position according to the light environment control parameter;

[0135] During the self-study period, the light source lighting is controlled according to the light environment control parameters in the area described in the learning scenario to provide learners with a suitable lighting environment, which helps to concentrate attention and improve learning efficiency.

[0136] S6. Acquire the learner's learning behavior information at a preset time before the end of the self-study period, wherein the learning behavior information includes: gaze tracking information and sitting posture information;

[0137] Before the end of the self-study period, learners' learning behavior information, including eye tracking information and sitting posture information, is obtained. The preset time before the end of the self-study period can be set according to the length of the self-study period. Both eye tracking information and sitting posture information can be obtained through video data obtained by cameras installed at each self-study position. Computer vision technology, such as deep learning algorithms (convolutional neural networks), is used to analyze eye dynamics in the video data, analyze learners' eye movements, blink frequency, and gaze points, and determine their focus of attention. Sitting posture information is also obtained using computer vision technology. A posture recognition algorithm such as OpenPose is used to analyze the learner's posture. By analyzing the video data, the learner's sitting posture, body inclination, etc. are identified to assess whether their posture is correct and whether they show signs of fatigue.

[0138] The eye tracking information includes the learner's eye movement information, gaze stability, blink frequency, and gaze point change information. Eye movement information includes the path, speed, and frequency of eye movement. Rapid or irregular eye movements may indicate that the learner is quickly scanning or searching for information, which may indicate unfamiliarity with the material or difficulty understanding it. Smooth and regular eye movements are more likely to indicate in-depth reading and understanding. Gaze stability refers to the degree to which the learner's gaze remains stable in a specific area (such as a certain point on a page or screen). Highly stable gaze is usually associated with highly focused attention. Frequent shifts in gaze may indicate distraction or difficulty focusing on a specific task. Blink frequency refers to the number of blinks in a certain period of time. A normal or slightly lower blink frequency may be associated with good concentration and a comfortable visual experience. An excessively high blink frequency may be a sign of visual fatigue, stress, or distraction. Gaze point change refers to the shifting of gaze from one focus to another. Frequent changes in gaze may indicate that the learner is having difficulty concentrating or is quickly browsing information. A stable gaze point is usually associated with more focused attention and in-depth understanding.

[0139] The sitting posture information includes sitting posture stability. Frequent changes in sitting posture may be a sign of discomfort or lack of concentration, while a stable sitting posture usually indicates that the learner is comfortable and able to concentrate.

[0140] S7. Obtaining the learner's attention level based on the learning behavior information and the human body sensing information, wherein the rate of change of the illumination parameter is inversely proportional to the attention level;

[0141] Specifically, this step evaluates the learner's attention level based on the learning behavior information and the body sensor information. The body sensor information can be used to obtain the frequency of the learner leaving the self-study position during the self-study period. Combined with the learning behavior information, the learner's attention level can be evaluated.

[0142] Specifically, the attention level can be obtained through the following steps:

[0143] S71. Obtain the frequency of leaving the self-study position during the current self-study period based on the human body sensing information, and record it as a leaving frequency;

[0144] Specifically, according to the human body sensing information obtained by the human body sensing sensor, the number of times the learner leaves the self-study position during the self-study period is obtained and recorded as the leaving frequency;

[0145] S72, obtaining the attention level by presetting the attention according to the frequency of leaving, eye movement information, line of sight stability, blink frequency, gaze point change information, and sitting posture stability;

[0146] This step first quantifies the frequency of eye movement, eye movement information, gaze stability, blink frequency, gaze point change information, sitting posture stability, and head posture to obtain the value of each parameter. The blink frequency uses eye tracking technology to record the number of blinks in a certain period of time, and then calculates the average number of blinks per minute or hour; the gaze point change is converted into the frequency of gaze point change per minute or hour by recording the number of times the learner changes the focus of their gaze within a certain period of time. Gaze stability is quantified as the average gaze duration by analyzing the length of time the eyes stay on a specific target. Sitting posture stability is evaluated by using posture recognition technology to assess the learner's sitting posture change frequency, such as the number of sitting posture adjustments per hour;

[0147] Then, based on the quantified parameters, different weights are assigned according to their impact on attention. For example, gaze stability may have a greater impact on attention, so it is given a higher weight. The weighted scores of each indicator are added together to obtain the learner's attention level.

[0148] S8. determining a rate of change of a lighting parameter according to the attention level and a difference between the light environment control parameter and a preset resting lighting parameter;

[0149] This step determines the rate of change of the lighting parameters based on the learner's attention level and the difference between the light environment control parameters and the preset resting lighting parameters, wherein the attention level and the rate of change of the lighting parameters are inversely proportional; that is, the rate of change is slow when the attention level is high, and the rate of change is fast when the attention level is low; when the user is in a highly concentrated state, a rapidly changing environment (such as a sudden change in light) may interrupt their attention. Slowly adjusting the lighting can reduce this interference and help users stay focused. When the user's attention level decreases, it may be a signal of fatigue or the need for rest. At this time, quickly adjusting the lighting can more effectively guide the user into a resting state, such as creating a more relaxing environment by reducing the brightness.

[0150] The benefit of this approach is that it optimizes the environment settings based on the user's current psychological and physiological state. By being sensitive and responsive to user behavior, a more humane and efficient learning or working environment can be created.

[0151] In one embodiment, the illumination parameter change rate is calculated using the following formula:

[0152]

[0153] Where k is a constant used to adjust the overall size of the rate of change of the illumination parameters; A is the normalized attention level, ΔL and ΔC are the rates of change of the brightness parameters and color temperature brightness, respectively; T rest is the rest period, p is the adjustment time window factor, WL 、W C Respectively represent the weights of brightness parameters and color temperature brightness in the rate of change of lighting parameters. According to different scenarios and user needs, the weights can be adjusted to optimize the effect of lighting adjustment;

[0154] Where (1-A) indicates that when the attention level is low, the adjustment rate increases; when the attention level is high, the adjustment rate slows down. p is the adjustment time window factor. If you want to complete the adjustment within 1 / 4 of the rest period, then p = 1 / 4. If you want to complete the adjustment within 1 / 2 of the rest period, then p = 1 / 2. The adjustment time window factor is adjusted according to the actual situation.

[0155] The formula-based adjustment rate allows for gradual changes in lighting, rather than abrupt switches. This helps users gradually adapt to changes in ambient light, reduces discomfort, and promotes a restful state without affecting concentration.

[0156] S9. During the rest period, according to the rate of change of the lighting parameter, control the light source to switch from the light environment control parameter to the preset rest lighting parameter.

[0157] During the rest period, the light source is controlled to transition from the current light environment control parameter to the preset rest light parameter according to the calculated light parameter change rate, wherein the preset rest light parameter can be the light environment control parameter of the area where the aforementioned rest scene is located.

[0158] By adjusting the rate of change based on attention levels, a smooth transition can be provided for learners when they are highly focused, avoiding discomfort caused by sudden changes in lighting, especially when working in high concentration. Rapidly adjusting the lighting when attention levels decrease can help to quickly change the environment to promote rest and recovery, thereby creating a clear boundary between learning and rest.

[0159] Example 2

[0160] In a second aspect, an embodiment of the present invention provides a healthy lighting system for a study room based on dynamic adjustment of lighting parameters, using the healthy intelligent lighting method for a study room as described in the first aspect above, the system comprising:

[0161] The first lighting module is used to provide ambient brightness for the activity scene in the study room;

[0162] The second lighting module is used to provide lighting for the self-study position in the learning scene;

[0163] A human body sensing module, used for providing the second lighting module with sensing information of a learner in the self-study position;

[0164] The calculation and control module is used to perform intelligent calculations on the lighting mode and control the light environment according to the activity scene.

[0165] Furthermore, the first lighting module includes multiple lighting modules, and the lighting modules are arranged according to the size and shape of the study room to provide uniform ambient brightness;

[0166] The second lighting module includes a high color temperature module, a low color temperature module, a white light module and a colored light module. The high color temperature module is used to provide cool color temperature lighting for the study position; the low color temperature module is used to provide warm color temperature lighting for the study position; the white light module is used to provide white light lighting for the study position; the colored light module includes red light, blue light and yellow light, and the colored light module is used to provide colored lighting for the study position.

[0167] Furthermore, the calculation and control module is also used to adjust the light environment of the first lighting module or the second lighting module according to the learner's adjustment instruction.

[0168] See Figure 5 In this embodiment, the study room's lighting is divided by providing a first lighting module and a second lighting module, thereby creating a zoned lighting scene. Because the required lighting intensity for the study room differs from that for study, the second lighting module is initially configured for study purposes. This module provides higher lighting intensity and color temperature adjustment. The first lighting module, on the other hand, provides the brightness required for specific activities in the study room. This module is evenly distributed throughout the study room according to its size and layout, and can be adjusted as needed. When learners are sitting in the study position to study, the second lighting module is activated for study. When learners are not in the study position, only the first lighting module can be used to meet general lighting needs. This can avoid the energy waste caused by using only one lighting module in the study room to make the light "always on" and the inability to adjust according to actual conditions. Also, because only one set of lighting modules is used, this set of lighting modules often requires high illumination intensity to meet learning needs, which makes the energy consumption of the light always on higher. The design of the human body sensing module can combine learner information with the study position reservation information to control the light to turn on, which is more intelligent. Under the above premise, a calculation and control module is set up. The calculation and control module includes an app and a mini-program. A variety of healthy lighting modes can be selected on the app and the mini-program. Learners can adjust the color temperature and brightness of the study light of the second lighting module and adjust the switch and brightness of the first lighting module according to current learning needs.

[0169] The second lighting module includes multiple tubes or bulbs with different color temperatures, which can be adjusted to suit learners' needs. Higher color temperatures (cooler tones), typically between 5000K and 6500K, can improve concentration and alertness. This cool light is believed to help improve learners' concentration and stimulate active thinking. It can enhance mental alertness, making learners more focused and energetic. Lower color temperatures (warmer tones), typically between 2700K and 4000K, can promote relaxation and rest. This warm light is considered softer and more comfortable, helping to reduce tension and create a more peaceful learning atmosphere. Lower color temperatures can help learners relax their minds, reduce eye strain, and provide a more comfortable learning environment. The optimal color temperature varies depending on individual differences and learning tasks. Some learning tasks may require high concentration and focus, so higher color temperatures may be more suitable; while others that require creativity and relaxation may prefer lower color temperatures. This color temperature can be adjusted based on changing learning time and context. For example, in the morning or for learning tasks that require increased alertness, choose lighting with a higher color temperature; in the evening or for learning tasks that require relaxation, choose lighting with a lower color temperature. Color temperature switching and selection can be achieved by using any one or a combination of cool light modules, warm light modules, and white light modules, as well as adjusting the brightness of different color temperature modules to create a variety of customized lighting modes. Different people may have different perceptions and preferences for color temperature, and can be adjusted and optimized according to actual conditions to meet the learning lighting needs of more diverse groups of people.

[0170] Secondly, different colors of light can affect people's mood and attention. By adjusting the color and color combinations of lighting, learners' thinking, concentration, and creativity can be stimulated. Vibrant colors and high-contrast lighting can increase learners' stimulation and alertness. The present invention achieves a variety of color temperatures by adjusting any one of the blue, yellow, and red light groups, or any combination thereof. Using bright colors, rainbow lighting, and other methods can create a more active and vibrant learning environment. By adjusting the color temperature and color by adding blue, yellow, and red light, and by varying the brightness of the lighting system, the present invention can provide positive encouragement or remind learners to focus. Different colors and color combinations can be used to influence learners' thinking and emotional states. Blue is considered a calming and focused color, enhancing attention and concentration. Therefore, blue-toned lighting can be used when learning scenarios require high concentration and focus. Yellow is considered a warm and friendly color, promoting creativity and positive emotions. Therefore, using yellow or orange-toned lighting may have a more positive impact on creative and inspirational learning tasks. Red is considered stimulating and exciting, increasing alertness and energy. When you need to stimulate thinking or carry out high-intensity learning tasks, you can try using red-toned lights. The lighting system can adjust the color and color of the light to produce different influences and effects, thereby better meeting the needs of learners and improving the adaptability of the learning environment.

[0171] The first lighting module includes multiple lighting modules, and the distribution and number of the lighting modules are customized based on environmental factors such as the size and shape of the study room, its area distribution, and the lighting conditions of the study room. The first lighting module primarily provides ambient brightness. The preset brightness of the first lighting module can be set according to different time periods of the day. For example, the lighting brightness requirement is higher in the morning and evening, while the lighting requirement can be met by reducing the brightness at noon. In another embodiment, to improve the adaptability of the lighting intensity and adapt to different indoor lighting conditions under different weather conditions, a light intensity detection module is combined to detect the indoor brightness in real time. By comparing the detection result with the preset brightness corresponding to the time period, the first lighting module is controlled to illuminate the room to achieve the preset brightness. This configuration can further reduce energy consumption. When the weather is clear and the indoor brightness is high, the first lighting module can be adjusted to provide a lower brightness to meet the lighting requirement. When the weather is bad and the indoor brightness is low, the first lighting module can be adjusted to provide a higher brightness to meet the lighting requirement. Furthermore, to further reduce energy consumption, the brightness provided by natural light to the study room can be fully utilized. When the indoor brightness reaches a certain level, the first lighting module can be set not to be turned on. When the indoor brightness is detected to be below the standard, the first lighting module is controlled to be turned on for lighting.

[0172] The computing and control module's app and mini-program provide a control platform and transmission channel for control. Learners can choose existing lighting modes according to their personal needs, or they can customize the first and second lighting modules to suit their needs. The computing and control module can communicate with the study space reservation system. When a study space is reserved, the lighting at the study space can be adjusted in advance. Learners set the lighting mode in advance. When a learner begins to use the study space, the first lighting module directly controls the lighting according to the learner's settings.

[0173] In another embodiment, the learning behavior data of the learner is obtained through a data acquisition module, wherein the learning behavior data includes learning time, attention level, and number of breaks;

[0174] When the learning time is equal to a preset learning time threshold, the number of breaks taken by the learner during the learning time is detected. When the number of breaks is less than the preset break threshold, the light of the second lighting module is controlled to change, reminding the learner to move around and take a break in time.

[0175] When the number of breaks taken by the learner during the learning time is greater than or equal to a preset break number threshold, detecting the learner's attention level; if the attention level does not reach the preset attention level threshold, controlling the color temperature module of the second lighting module to change, so as to remind the learner to concentrate;

[0176] When the attention level reaches a preset attention level threshold, controlling the second lighting module to increase the lighting intensity to ensure learning effect;

[0177] Among them, the attention level data is obtained by detecting the person's eye gaze area and gaze duration; the lighting change includes brightness and darkness change and color temperature switching; the color temperature module includes any one of the cold light module, warm light module, white light module, blue light module, yellow light module and red light module or a combination thereof.

[0178] In this implementation, data on the learner's learning status is collected. Since learners may sit for extended periods of time in study rooms and not rest regularly, intelligent computing and analysis are used to control lighting changes to remind learners to take breaks. If a break is detected within the scheduled study time, the learner's attention level is monitored. The focus level is determined by measuring the learner's eye gaze area and duration within the designated learning area. If the learner's attention is not focused, the color temperature is controlled to switch to, for example, blue to improve concentration.

The brightness and color temperature of the lighting can also be adjusted for each independent activity scene according to the actual situation and user needs. Especially for learning scenes, learners can adjust the lighting mode in a targeted manner when reading books or using electronic devices, providing learners with a lighting mode that can relieve visual fatigue and protect the eyes. Two lighting modules are used, and an independent lighting module provides learning lighting for the learning scene and can intelligently adjust the brightness and color temperature. In addition, by combining the study room reservation information with the human body sensing information, it is ensured that the lighting module of the learning scene "is on when people are there and off when they leave", maximizing energy conservation and reducing energy waste caused by constant lighting. Secondly, different colors and color combinations are used to influence the learner's thinking and emotional state, providing positive encouragement to learners from the perspective of lighting, and improving learning efficiency.
