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

[0004] In some study rooms, firstly, the arrangement of lighting equipment may not be uniform and single, resulting in weak lighting intensity in some areas, while other areas may be too bright, without distinguishing the activity scenes and providing corresponding and appropriate lighting. Such unevenness will affect the comfort and visual experience of learners in different areas or activity scenes. Too strong light may cause glare and visual fatigue, affect learners' attention and concentration, and also cause discomfort to those who are resting. Too weak light will make the learning environment dim, affecting learners' ability to read and perceive information. Secondly, the lighting in the study room cannot be reasonably set according to the actual scene. When in the learning scene, different color temperature and brightness settings are required, and inappropriate color temperature and brightness may affect learners' comfort and attention. The lack of adjustable color temperature and brightness options also limits learners' personalized needs. In addition, some study rooms also have the problem of lights being on for a long time, and they maintain high brightness even when no one is using them. This waste of energy is not only unfriendly to the environment, 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 purpose, technical solutions and advantages of the present invention clearer, 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 only to provide a better understanding of the present invention by illustrating examples of the present invention.

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

[0065] In some study rooms, firstly, the arrangement of lighting equipment may not be uniform and single, resulting in weak lighting intensity in some areas, while other areas may be too bright, without distinguishing the activity scenes and providing corresponding and appropriate lighting. Such unevenness will affect the comfort and visual experience of learners in different areas or activity scenes. Too strong light may cause glare and visual fatigue, affect learners' attention and concentration, and also cause discomfort to those who are resting. Too weak light will make the learning environment dim, affecting learners' ability to read and perceive information. Secondly, the lighting in the study room cannot be reasonably set according to the actual scene. When in the learning scene, different color temperature and brightness settings are required, and inappropriate color temperature and brightness may affect learners' comfort and attention. The lack of adjustable color temperature and brightness options also limits learners' personalized needs. In addition, some study rooms also have the problem of lights being on for a long time, and they maintain high brightness even when no one is using them. This waste of energy is not only unfriendly to the environment, but also increases energy costs.

[0066] Example 1

[0067] To solve the above problems, see Figure 1 , an 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, there are not only study areas but also rest areas. When learners feel tired after studying for a long time, they can take a rest in the rest area. Providing different lighting modules and light environments for different activity scenes can assist learners in learning better or resting better. In one embodiment, the distinction of activity scenes in 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 in 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. The postures and activities of people in the study room can be analyzed based on machine learning algorithms. For example, the postures of sitting to study and lying to 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, and classification is performed according to the postures and activity states, so as to distinguish 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 attention, 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 lights can relieve stress, reduce eye fatigue, and help adjust the biological clock and 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 of 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 of the area where the learning scene is located according to the first color temperature value and the first brightness value. A lighting mode with high color temperature and higher brightness can be used for the learning area to meet the learner's needs for learning lighting and improve the learner's concentration; and the learning area usually requires 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 area where the learning scene is located 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 autonomously 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 not only improves lighting efficiency by intelligently adjusting the lighting environment in different areas of the study room, but also creates an environment conducive to learning and resting. This approach can protect eyesight and improve learning efficiency while also taking 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 the learning scene and the rest scene in each time period, 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: The first brightness value preset value: 500-700l x; The first color temperature value preset value: 5500-6500K; The second brightness value preset value: 300-500l x; The second color temperature value preset value: 4000-5500K;

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

[0085] Evening: The first brightness value preset value: 300-500l x; the first color temperature value preset value: 5000-6000K; the second brightness value preset value: 250-400l x; the second color temperature value preset value: 3500-5000K;

[0086] Select preset values ​​corresponding to the first brightness value, the second brightness value, the first color temperature value, and the second color temperature value according to the current time, use the light sensor to monitor the ambient light data in real time, and dynamically adjust the brightness and color temperature of the indoor lighting according to the ambient light data. If the external light is strong, reduce the brightness of the indoor lighting to avoid unnecessary energy consumption and excessive lighting. If the external light is dim, increase the brightness of the indoor lighting to ensure sufficient light, and adjust the color temperature to supplement the color characteristics of natural light, such as using warmer light on a cloudy day to balance the blue tone 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 learning scenario of the learner 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 self-study position. The electronic device includes a mobile phone, a laptop computer, a tablet computer, etc. It is determined whether the current learner's learning scene is 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 books or using electronic devices can be achieved by detecting specific spectral features of the electronic screen through an ambient light sensor. Electronic screens, especially LCD or LED screens, usually emit light of specific wavelengths, which can be captured by specific sensors. When specific spectral features are captured, it can be determined that the current learner's learning scenario is using electronic devices, otherwise the previous learner's learning scenario is reading books.

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

[0092] When the learner is in the scene of reading a book, the color temperature parameter of the light environment control parameter of the area where the learning scene is located is set to white color temperature. White color temperature (i.e. white light) usually has the characteristics of high brightness and full spectrum, which can provide high contrast and make the text clearer and easier to recognize. This is very important for reading books, because clear text can help readers better understand the content and reduce the possibility of reading misunderstandings. Brighter white light can stimulate the brain and increase alertness, which helps to improve reading concentration and attention persistence. This is very beneficial for dealing with more complex or concentrated learning tasks, allowing readers to better immerse themselves in books without external interference. White light is believed to adjust people's biological clocks, improve alertness and attention. Especially when reading books, staying alert can promote thinking and understanding, and help the depth and quality of learning. However, too bright white light may cause a certain degree of fatigue to the eyes. Therefore, when reading books, moderately controlling the lighting brightness and avoiding too bright light directly shining on the eyes can reduce eye discomfort and fatigue, allowing learners to concentrate on reading for a long 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] In the scenario of using electronic devices, the color temperature parameter of the light environment control parameter is yellow light color temperature, which can reduce exposure to blue light and reduce eye fatigue and visual stress. Electronic devices (such as smartphones, tablets, computer displays, etc.) usually emit more blue light. Blue light has high energy and short wavelength, which is easy to scatter and penetrate the eyes, causing certain optical damage and visual fatigue to the eyes. Blue light is the main light source of electronic devices. Long-term exposure to blue light can easily cause eye fatigue, dryness and visual discomfort. Yellow light has a lower blue light component, which helps to reduce eye fatigue. Therefore, the use of yellow light can effectively inhibit the impact of blue light, reduce the stimulation of blue light to the eyes, and reduce visual fatigue and eye discomfort. Compared with blue light or white light, yellow light has a lower color temperature and creates a softer and warmer environment. Such light can reduce the visual burden of the eyes, reduce glare and reflection, and make the visual experience more comfortable and natural. Make learners use electronic devices more comfortable. Intelligent control according to the scene where the learner is located can provide a personalized learning environment, and the lighting mode adjustment in different learning scenes can meet the needs of learners and improve learning effects and comfort. This personalized light environment setting can help learners focus better on learning and improve learning efficiency.

[0095] Secondly, in order to solve the problem that the blue light generated by electronic devices can easily cause eye fatigue in learners, you can also choose lights with soft and even lighting to avoid strong light and excessive contrast of shadows. Providing even and stable light can help reduce eye fatigue. According to personal needs and lighting environment, reasonably adjust the brightness of the light around electronic devices to avoid stimulation of too bright or too dark light 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 area where the learning scene is located to yellow light color temperature and increasing the first brightness value, further comprising:

[0097] S224, monitoring the continuous time that the learner uses the electronic device, and comparing the continuous time with a preset time threshold;

[0098] In this embodiment, no matter what kind of light is 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, relax your eyes and do eye exercises, which can help relieve eye discomfort and fatigue. Therefore, in this embodiment, when it is identified that a learner is using an electronic device to study in a self-study position, the use time of the learner's electronic device is synchronously detected and calculated, and the use 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 needs for lighting. 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 according to personal needs. Through this method, 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 it is identified that a learner is using an electronic device to study at the self-study position, the usage time of the learner's electronic device is synchronously detected and calculated. When the learner's use of the electronic device reaches the preset usage time, the light is changed to remind the learner to take a break in time and look into the distance to relieve eye fatigue. After the light changes to remind, the usage time of the learner's electronic device is reset. When the reset time reaches the preset usage time again, the light is changed again to remind. If the learner leaves the self-study position within the preset usage time or changes to a reading method, the usage time of the electronic device is stopped. When the learner uses the electronic device again, the usage time is reset.

[0102] In another embodiment, when learners alternate between using electronic devices or books to study, it is necessary to monitor the duration of the learners' interruption of the use of electronic devices. If the duration of the interruption of the use of electronic devices is within a certain preset interruption range, the timing of the use time of the electronic devices will not be stopped. For example, if the preset interruption range is 5 minutes, when it is detected that the learners interrupt the use of electronic devices, the duration of the learners' interruption of the use of electronic devices is timed. If the interruption duration is less than 5 minutes, the interruption duration will continue to be counted in the use time of the electronic devices. When the use time of the electronic device reaches the preset use time, the light changes to remind the learners to take a break in time.

[0103] In another embodiment, based on the above embodiment, when learners alternately use electronic devices or books to study, when it is detected that the learner is reading a book, the light is switched to white light and the brightness is appropriately reduced; when it is detected that the learner uses the electronic device again, the light is switched to yellow light and the brightness is appropriately increased. The switching of the light should be performed in a slow transition manner to prevent the drastic light switching from interfering with the learner's learning 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 area where the learning scene is located to yellow light color temperature and increasing the first brightness value, further comprising:

[0105] S226, obtaining position information of a display screen of the electronic device;

[0106] Specifically, when the illumination light directly shines on the display screen, the light reflection on the display screen surface will be relatively reduced, and part of the incident light will be absorbed or scattered by the display screen, and will not be completely reflected back to the eyes. The rebound of the reflected light can be reduced, and the interference caused by the reflected light entering the eyes can be reduced. Secondly, the illumination directly shining on the display screen can reduce glare. Glare is a visual sensation caused by strong light stimulation, which makes the eyes feel dazzling and uncomfortable. When the illumination light directly shines on the display screen, part of the light will be absorbed or scattered by the display screen, reducing the intensity of the light directly incident on the eyes. This can reduce the intensity of glare and make the eyes feel a more comfortable light environment.

[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, so as to accurately obtain 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 in the area where the display screen is located. This can reduce glare and reflection, 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 and avoid overly bright or dark areas. This helps to create a more comfortable and coordinated lighting environment and reduce the possibility of visual discomfort. Maintain 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, by real-time tracking of the position of the display screen and the tilt angle of the display screen, the illumination angle is adjusted in real time so that the illumination light forms an angle less than 90 degrees with the display screen. Generally, the angle is preferably between 30 and 45 degrees, and learners can also adjust the angle range according to the type of display screen, ambient lighting conditions, and personal visual perception.

[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 according to 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 eye fatigue caused by too strong contrast. On the contrary, 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, a higher color temperature (blue light) increases 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, you can choose to use lighting with a lower color temperature (such as yellow light or warm light) to balance the color temperature of the display screen and reduce the stimulation of blue light to the eyes; when the blue light of the screen is strong, control the brightness of the enhanced yellow light or warm light 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 above steps, the light source of the study room can be controlled to provide targeted lighting for different scene types in the study room, thereby providing a comfortable and efficient learning environment. At the same time, this system also helps to 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 for lighting 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 reservation study position information and reservation duration information;

[0116] Specifically, the study room location is reserved in advance through the system, and the specific study location is selected according to the learner's preference, so the reservation information can be obtained through an online reservation system. The reservation information includes the reservation location and duration. The human body 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 there is reservation information at the self-study position, judging whether there is a learner at the corresponding self-study position according to the human body sensing information;

[0118] When there is reservation information at the self-study position and the reservation time period has arrived, judging 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, controlling 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 a low power consumption mode or turn it off.

[0122] If there is no learner at a reserved study position, the system switches the lighting at that position to low power mode or turns it off completely, and automatically reduces or turns off the lighting at unused study positions through an intelligent control system. In low power mode, the light can be maintained at a very low brightness to save energy while making it easier for learners to find their reserved positions. The implementation of this solution can significantly improve the energy efficiency of the study room while providing learners with a personalized and comfortable learning environment. By combining reservation information and human body sensing technology, the system can manage lighting resources more intelligently and efficiently.

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

[0124] S341, when the learner leaves the self-study position, judging whether the self-study position is still within the reservation time according to the reservation time information;

[0125] Specifically, in order to provide a more intelligent method to prevent the lights from being always on, the situation of the learner leaving the self-study position is distinguished. The learner may leave the self-study position for a short time, for a long time, or leave the self-study room after finishing learning. In this step, when the learner leaves the self-study position, it is judged by human body sensing information, and whether the self-study position is still within the reservation time according to the reservation time information;

[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 the preset absence time, controlling the lighting of the self-study position 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 self-study position is maintained unchanged;

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

[0130] Specifically, when the learner is away for a short time, the preset departure time can be set. For example, if the preset departure time is 10 minutes and the self-study position is still within the reservation time period, the self-study position detects that the learner is away for less than 10 minutes and maintains the lighting mode unchanged; when the learner leaves the self-study position for more than ten minutes, it switches to low power mode, and uses the method of reducing the lighting brightness and color temperature to remind other learners that the learner at the self-study position is away for a short time, and reduces the lighting power consumption to prevent energy waste. When the self-study position exceeds the reservation time period, the light automatically and slowly reduces the brightness to remind the learner to renew the contract in time or remind the learner that the reservation time is approaching. If the learner does not renew the contract after the timeout, the lighting is controlled to be turned off. Some self-study positions have not exceeded the reservation time and learners leave the study room first to end their studies. Learners can end their studies in advance on the app or mini program, and the self-study position automatically turns off the lights; when the learner does not actively end their studies and the departure time exceeds 10 minutes, the light will first switch to low power mode, and wait until the reservation time is exceeded, and then the self-study position lighting will be automatically turned off.

[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 according to the reservation duration information and the preset concentration time range, wherein the self-study time schedule includes a plurality of self-study time periods and rest time periods that are alternately set;

[0133] Specifically, this step first generates a number of alternating self-study time periods and rest time periods based on the appointment time 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, some psychology and ergonomics research can be referred to. 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 25-50 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 5 minutes of rest time. The short rest time is recommended to be 5-10 minutes, which is enough for the brain to relax and recover. After several study cycles, a longer break can be arranged, such as 15-30 minutes; according to the appointment duration and the above time range, a schedule including alternating study and rest time periods is generated. For example, if a learner has made an appointment for 3 hours, it can be arranged as 4 25-minute study time periods, each followed by a short break of 5 minutes, and a longer break period to end the self-study. 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 and improve learning efficiency.

[0136] S6. obtaining 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 can be set according to the length of the self-study period. Eye tracking information and sitting posture information can be obtained through video data obtained by cameras set at each self-study position. Computer vision technology, such as deep learning algorithms (convolutional neural networks), is used to analyze eye dynamics in video data, analyze learners' eye movements, blinking frequency and gaze points, and determine their focus of attention; sitting posture information is also obtained using computer vision technology, using posture recognition algorithms such as OpenPose to analyze learners' postures. By analyzing video data, learners' sitting postures, body inclinations, etc. are identified to evaluate whether their postures are correct and whether they show signs of fatigue;

[0138] The eye tracking information includes the learner's eye movement information, line of sight stability, blinking frequency, and fixation point change information. Eye movement information includes the movement path, speed, and frequency of the eyeballs. Rapid or irregular eye movements may indicate that the learner is quickly scanning or searching for information, and may be unfamiliar with the material or have difficulty understanding it. Smooth and regular eye movements are more likely to indicate in-depth reading and understanding. Line of sight stability refers to the degree to which the learner's line of sight remains stable in a specific area (such as a certain point on a page or screen). Highly stable lines of sight are usually associated with highly concentrated attention. Frequent shifts in line of sight may indicate distraction or difficulty focusing on a specific task. Blinking frequency refers to the number of blinks in a certain period of time. Normal or slightly lower blinking frequencies may be associated with good concentration and a comfortable visual experience. Excessive blinking frequencies may be a sign of visual fatigue, stress, or distraction. Fixation point changes refer to the shifting of lines of sight from one focus to another. Frequent changes in fixation points may indicate that learners have difficulty concentrating or are quickly browsing information. Stable fixations are usually associated with more concentrated 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. Acquire the learner's attention level according to 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 human body sensing information. The human body sensing 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 by following the steps below:

[0143] S71, obtaining the frequency of leaving the self-study position in the current self-study time period according to the human body sensing information, and recording it as the 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 leaving frequency, eye movement information, sight line stability, blinking frequency, gaze point change information, and sitting posture stability;

[0146] This step first quantifies the frequency of leaving the eye, eye movement information, line of sight stability, blinking frequency, fixation point change information, sitting posture stability and head posture to obtain the value of each parameter. The blinking 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 fixation point change is converted into the frequency of fixation point change per minute or hour by recording the number of times the learner changes the focus of their sight within a certain period of time. The line of sight stability is quantified as the average fixation 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 the degree of influence of each parameter on attention. For example, sight stability may have a greater impact on attention, so it is assigned a higher weight, and 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 is inversely proportional to the rate of change of the lighting parameters; 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 sudden changes 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 according to 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 by the following formula:

[0152]

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

[0154] Wherein, (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, and p is the adjustment time window factor. If the adjustment is expected to be completed within 1 / 4 of the rest period, then p = 1 / 4; if the adjustment is expected to be completed 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 adjustment rate calculated according to the formula can achieve a gradual change in lighting instead of an abrupt switch. 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 may 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 level, it can provide a smooth transition for learners when they are highly focused, avoiding the discomfort caused by sudden changes in lighting, especially when working in high concentration. Rapidly adjusting lighting when attention levels decrease can help 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 illumination parameters, using the healthy intelligent lighting method for a study room as described in the first aspect above, and the system includes:

[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 at a 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 a plurality of 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 cold color temperature lighting for the self-study position; the low color temperature module is used to provide warm color temperature lighting for the self-study position; the white light module is used to provide white light lighting for the self-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 self-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 also Figure 5 In this embodiment, the lighting of the study room is divided by setting the first lighting module and the second lighting module, so that the lighting scene can be divided. Since the lighting intensity required for the study room is different from the lighting intensity required for learning, the second lighting module is first set for the lighting purpose of learners' learning. The second lighting module can provide a higher lighting intensity and color temperature adjustment function; and the first lighting module is set to provide the brightness required for certain activities in the study room, which is evenly distributed in the study room according to the size and layout of the study room, and is adjusted according to needs. When learners are sitting in the study position to study, the second lighting module is enabled 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 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 the 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 learning light of the second lighting module according to current learning needs, and adjust the switch and brightness of the first lighting module.

[0169] The second lighting module includes a plurality of tubes or bulbs with different color temperatures, and the color temperature can be adjusted according to the needs of learners. A higher color temperature (cool tone) is usually a color temperature between 5000K and 6500K, which can improve attention and alertness. This cool-toned light is believed to help improve learners' concentration and promote active thinking. It can enhance the brain's alert state, making learners more focused and energetic. A lower color temperature (warm tone) is usually a color temperature between 2700K and 4000K, which can help relax and rest. This warm-toned light is considered to be softer and more comfortable, helping to reduce tension and create a more peaceful learning atmosphere. A lower color temperature can help learners relax their brains, reduce eye fatigue, and provide a more comfortable learning environment. In addition, the best color temperature selection will also vary depending on individual differences and different learning tasks. Some learning tasks may require a high degree of attention and concentration, so a higher color temperature may be more suitable; while for some learning tasks that require creativity and relaxation, a lower color temperature may be more suitable. It can be adjusted according to changes in learning time and scene. For example, in the morning or for learning tasks that require 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. The switching and selection of color temperature can be achieved through any one or a combination of cold light modules, warm light modules, and white light modules, as well as the brightness adjustment of different color temperature modules. Different people may have different feelings and preferences for color temperature, and can be adjusted and optimized according to actual conditions to meet the learning lighting needs of more different groups of people.

[0170] Secondly, different colors of lights will affect people's emotions and attention. By adjusting the color and color combination of lights, learners' thinking, concentration and creativity can be stimulated. Bright colors and high-contrast lighting effects can increase learners' stimulation and alertness. The present invention can obtain a variety of different color temperatures by setting any one of the blue light, yellow light and red light groups or their combinations, and use bright colors, rainbow lights, etc. to provide a more active and lively learning environment. The present invention adjusts the color temperature and color by adding blue light, yellow light and red light, and the lighting system can change the brightness of the light to provide positive encouragement or remind learners to concentrate. Different colors and color combinations can be used to influence learners' thinking and emotional states. Blue is considered to be a calm and focused color that can improve attention and concentration. Therefore, when the learning scene requires high attention and concentration, blue-toned lights can be used. Yellow is considered to be a warm and friendly color that can promote creativity and positive emotions. Therefore, in creative and inspirational learning tasks, using yellow or orange-toned lights may have a more positive impact. Red is considered to have stimulating and exciting properties that can increase alertness and vitality. 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 according to the size and shape of the study room, the area distribution, and the lighting of the study room. The first lighting module mainly provides environmental brightness. First, the preset brightness of the first lighting module can be set according to different time periods of the day. For example, the lighting brightness demand is higher in the morning and evening, and the lighting demand can be met by reducing the lighting brightness at noon. In another embodiment, in order to improve the adaptability of the lighting intensity and adapt to the different lighting conditions of indoor brightness under different weather conditions, the indoor brightness is detected in real time in combination with the light intensity detection module. By comparing the detection result with the preset brightness corresponding to the time period, the first lighting module is controlled to illuminate so that the indoor brightness reaches the preset brightness. This setting 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 demand; when the weather is bad, the indoor brightness is low, and the first lighting module is adjusted to provide a higher brightness to meet the lighting demand. Furthermore, in order to maximize the reduction of energy consumption, the brightness brought 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 it is detected that the indoor brightness does not meet the standard, the first lighting module is controlled to be turned on for lighting.

[0172] The app and applet of the calculation and control module provide a control platform and transmission channel for control. Learners can choose existing lighting modes according to their personal needs, or they can personalize the first lighting module and the second lighting module according to their own needs. The calculation and control module can communicate with the self-study position reservation system. When reserving a self-study position, the lights of the self-study position can be adjusted in advance. Learners set the lighting mode in advance. When learners start using the self-study position, the first lighting module directly controls the lighting according to the learner's setting information.

[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 rest times;

[0174] When the learning time is equal to the preset learning time threshold, the number of rest times of the learner within the learning time is detected, and when the number of rest times is less than the preset rest time threshold, the light of the second lighting module is controlled to change to remind the learner to move and rest 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, the learner's attention level is detected; when the attention level does not reach the preset attention level threshold, the color temperature module of the second lighting module is controlled to change 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 the learning effect;

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

[0178] In this embodiment, data is collected on the learning status of the learner. Since the learner may sit for a long time and not take a rest in time when studying in the study room for a long time, in order to improve the learner's healthy learning, the light change is controlled by intelligent calculation analysis to remind the learner to take a rest in time. When it is detected that the learner has taken a rest within the predetermined learning time, the learner's attention level is detected. The attention level is obtained by detecting whether the learner's eye gaze area and gaze duration are within the predetermined learning area. When the learner is not focused, the color temperature is controlled to switch to, for example, blue color temperature to increase the learner's concentration level.

[0179] Example 9

[0180] See also Figure 6An embodiment of the present invention provides a healthy lighting device for a study room based on dynamic adjustment of lighting parameters, including: at least one processor 401, at least one memory 402, and computer program instructions stored in the memory.

[0181] In addition, combined Figure 1 The healthy intelligent lighting method for a study room according to the embodiment of the present invention described above can be implemented by a healthy intelligent lighting device for a study room.

[0182] The healthy intelligent lighting device for a study room may include a processor and a memory storing computer program instructions.

[0183] Specifically, the processor 401 may include a central processing unit (CPU), or an application specific integrated circuit (ASIC), or may be configured to implement one or more integrated circuits of the embodiments of the present invention.

[0184] Memory 402 may include a large capacity memory for data or instructions. For example, but not limitation, memory may include a hard disk drive (HDD), a floppy disk drive, a flash memory, an optical disk, a magneto-optical disk, a magnetic tape, or a universal serial bus (USB) drive or a combination of two or more of these. In appropriate cases, memory 402 may include a removable or non-removable (or fixed) medium. In appropriate cases, memory 402 may be inside or outside a data processing device. In a specific embodiment, memory 402 is a non-volatile solid-state memory. In a specific embodiment, memory 402 includes a read-only memory (ROM). In appropriate cases, the ROM may be a mask-programmed ROM, a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), an electrically rewritable ROM (EAROM) or a flash memory or a combination of two or more of these.

[0185] The processor 401 reads and executes the computer program instructions stored in the memory 402 to implement any of the healthy lighting methods and systems for study rooms based on dynamic adjustment of lighting parameters in the above embodiments.

[0186] In one example, the study room healthy intelligent lighting device may further include a communication interface 403 and a bus 410. Figure 6As shown, the processor 401, the memory 402, and the communication interface 403 are connected via a bus 410 and communicate with each other.

[0187] The communication interface 403 is mainly used to implement the communication between the modules, devices, units and / or equipment in the embodiment of the present invention.

[0188] Bus 410 includes hardware, software or both, and the components of the healthy intelligent lighting equipment of the study room are coupled to each other.

The computer-readable storage medium stores computer program instructions; when the computer program instructions are executed by a processor, any healthy lighting method and system for study rooms based on dynamic adjustment of illumination parameters in the above embodiments are implemented.

[0190] In summary, the beneficial effects of the present invention are as follows: the healthy intelligent lighting method and system for the study room of the present invention can provide corresponding and appropriate lighting for different activity scenes by identifying activity scenes. For each independent activity scene, the brightness and color temperature of the lighting can also be adjusted according to the actual situation and user needs. Especially for the learning scene, 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 independent lighting modules are provided for learning scenes to provide learning lighting 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 on and off when people leave", maximizing energy conservation and reducing energy waste caused by constant lighting. Secondly, different colors and color combinations are used to influence the thinking and emotional state of learners, providing positive encouragement to learners from the perspective of lighting, and improving learning efficiency.

[0191] It should be clear that the present invention is not limited to the specific configuration and processing described above and shown in the figures.
