Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vision care, and relates to a device for exercising eye muscles, in particular to a desk lamp for exercising eye muscles. BACKGROUND

[0002] With the rise of electronic products, people cannot do without mobile phones or computers in work and life, and long-time use of eyes causes eye function tension, and the fatigue and tension of eye muscles cannot be effectively relieved, so that the accommodation ability of eye muscles is decreased. At present, the methods for training eye muscles mainly include eye care exercises and natural training methods such as rotating eyeballs and alternating focusing on near and far objects. At present, the main method for treating ametropia is to wear glasses, in addition, there are various instruments for stimulating acupoints developed through traditional Chinese medicine meridian theory.

[0003] In the prior art, CN 102551999B provides an eye muscle exercise device and an eye muscle exercise method. The application belongs to the field of vision care, and provides an eye muscle exercise device controlled by a single-chip microcomputer and a corresponding eye muscle exercise method. The device includes a rotating arm, an LED (Light Emitting Diode), a rack movement groove, a gear and a rack, a rotation angle sensor, a reduction DC motor, a stepping motor, a control circuit and an operation panel, a support rod telescopic rod and a height adjustment fastening part. The control circuit with the single-chip microcomputer as the core collects the position information of the rotating arm, controls the reduction DC motor and the stepping motor, drives the rotating arm to rotate in a circle, and simultaneously makes horizontal forward or backward movement according to the current position, guides the vision focus of the user to move around the head, controls the rotating arm to move according to a specific track according to the exercise method, exercises the eye muscles of the user, enhances the accommodation ability of the lens, and thus achieves the purpose of improving the vision of the user. However, the rotating arm with the hollow connecting rod in the shape of “L” in the device of the prior art is suitable for children and adolescents in the early stage of myopia. Children and adolescents in this age group are curious and active, and the user may not be in the predetermined standing position and height in the prior art during the entire eye muscle exercise period. Therefore, the device may cause a strike danger to the user, and the user may also hit the rotating arm in operation due to dizziness caused by rotating the eyeballs, and thus damage may occur. In addition, when the rotating arm moves around the head in a circle with the user's glabella as the center, the user may have great psychological pressure due to the fear of being hit, which is not conducive to the eye muscle exercise and recovery of myopia of the patient.

[0004] The prior art CN209048614U relates to an eye exercise instrument for exercising eye muscles and improving eyesight by physical means, comprising a main box as a base, on which an LED lamp belt and its support structure are installed, a mobile phone support and its mobile phone support base installed above the main box, a pupil camera capture and a camera, and a head support device; the head support device ensures that the distance between the user's eyes and the LED lamp belt is about 30 cm. The main box contains a smart chip set, a WIFI relay station and a sound control component; the smart chip set is connected to a mobile phone through the WIFI relay station; the smart chip set can also be connected to other display devices through the WIFI relay station, wired or wireless HDMI technology. The utility model has the advantages of low cost, simple and beautiful structure, changing the passive exercise mode of traditional eye protection instruments to active training, and the effect is more obvious than that of traditional eye protection instruments; but the eye exercise instrument of the prior art provides small exercise visual field, and cannot guarantee that the user will exercise the eyeball as much as possible. The eyeball rotation angle is small, the corresponding eye muscles cannot be fully stretched and contracted, the exercise effect is not good, and the device contains a mobile phone, which needs to be frequently selected to see the patterns on the mobile phone screen. The blue light emitted by the mobile phone screen hinders the recovery of the eyes.

[0005] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, the applicant has studied a large number of literatures and patents when making the invention, but due to the limitation of space, all the details and contents are not listed in detail, but this does not mean that the invention does not have these characteristics of the prior art, on the contrary, the invention has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY

[0006] For students, they need to spend a lot of time learning, especially students facing the entrance examination need to read, write and listen for a long time. The close distance between the eyes and the book will cause the eye muscles to be in a high contraction state all the time, which will reduce the tension of the eye muscles. For people who are in contact with electronic products for a long time, they usually have bad eye behaviors such as long time, close distance, etc. The long-term tight state of the ciliary body and the extraocular muscles will cause eye fatigue, eye muscle spasm and other problems, which may cause the elasticity of the ciliary muscle and the rectus muscle to decrease, and the buffering performance to be greatly weakened. When myopic eyes look at close objects, they need a large amount of convergence, which will increase the burden of the internal rectus muscle and cause visual fatigue. When using eyes at close distance, the ciliary muscle is in a high contraction state, and when the eyes are under high pressure for a long time, the adjustment and convergence of the extraocular muscles are persistent and frequent, and further, the effect will be applied to the sclera tissue and continuously extended, which will cause the eye axis to grow and the adjustment efficiency to decrease, thus increasing the possibility of myopia. With the passage of time, the ciliary muscle and the peripheral muscles of the eyes appear adverse changes, such as ciliary muscle fatigue, spasm, and finally cause pseudo myopia or myopia.

[0007] If the near or long time eye habits are not improved, the eye muscles will show serious fatigue symptoms, and further increase the degree of myopia. With the aggravation of myopia, other eye diseases can be induced, and eventually lead to multiple complications of eye diseases. Therefore, the eye muscles need to be exercised to relieve eye fatigue and avoid the occurrence of myopia as much as possible. Although the prior art provides products for preventing and treating myopia, there are problems of easy damage during exercise, insufficient eye movement guided, and inability to match appropriate exercise modes according to the actual fatigue degree of the eye of people with different eye habits.

[0008] Therefore, for the prior art, the present application provides a desk lamp for exercising eye muscles, comprising:

[0009] The lighting module with a plurality of light-emitting bodies arranged in a preset shape is configured to have a plurality of preset exercise lighting modes for exercising different eye muscles;

[0010] The detection module for acquiring eye information capable of reflecting the degree of eye fatigue and / or the activity of eye muscles, and

[0011] The control module provided on the desk lamp, the control module is configured to,

[0012] Based on the eye information detected by the detection module, the lighting module is controlled to exercise the user's eyes in a combination of exercise lighting modes adapted to the user's eye information, and the combination of exercise lighting modes changes include one or more of the exercise time length of different exercise lighting modes, the cycle number of different exercise lighting modes, the exercise sequence of different exercise lighting modes.

[0013] The setting of the lighting module provided by the present application diversifies the movement angle of the eye, sets specific exercise lighting modes for different eye muscles, and adjusts the combination of exercise lighting modes according to the actual eye information of the user to make the eye muscles fully stretch and contract.

[0014] Preferably, the exercise lighting modes of the desk lamp at least include:

[0015] A first mode for exercising the medial rectus and the lateral rectus;

[0016] A second mode for exercising the superior rectus and the inferior rectus;

[0017] A third mode for exercising the superior oblique and the inferior oblique;

[0018] A fourth mode for exercising the extraocular muscles.

[0019] The lighting module has both modes for individually exercising specific eye muscles and modes for overall exercising eye muscles, ensuring sufficient movement of the eye in left and right, up and down, and cross directions.

[0020] Preferably, the control module is configured to, when the blink frequency of the user is in the first range and reflects that the eye of the user is in a mild fatigue state, perform eye exercise on the user in a first exercise lighting mode combination, wherein,

[0021] The first exercise lighting mode combination is that the first mode, the second mode, the third mode and the fourth mode are performed in sequence. Mild fatigue indicates that the load of the eyeball muscle is small, and the eyeball muscle can be recovered by moderate exercise. The preset exercise lighting mode combination can achieve the purpose without additional exercise times or exercise time.

[0022] Preferably, the control module is configured to, when the blink frequency of the user is higher than the highest value of the first range and reflects that the eye of the user is in a severe fatigue state, control the detection module to open the detection mode of the activity degree of the eyeball muscle, and obtain the activity degree of the eyeball muscle to select a combination of exercise lighting modes matched with the muscle activity degree. When the detection result is severe fatigue, the detection module opens the detection mode of the muscle activity degree, confirms the eyeball muscle with low activity degree, and strengthens the exercise of the eyeball muscle with low activity degree, so as to strengthen the exercise effect by targeted exercise; and the detection of the activity degree of the eyeball muscle is only performed when the detection result is severe fatigue, so as to reduce the operation load of the detection module.

[0023] Preferably, the control mode is configured to, when it is detected that the activity degree of a specific muscle in the eyeball muscle is the second activity degree, increase the number of times or the exercise time of the mode of the exercise lighting mode corresponding to the exercise of the specific muscle, wherein,

[0024] The specific muscle refers to at least one part of the eye muscle detected at the second activity degree, including one or more of the medial rectus muscle, the lateral rectus muscle, the superior rectus muscle, the inferior rectus muscle, the superior oblique muscle and the inferior oblique muscle. The combination of the exercise mode matched with the fatigue degree of the eyeball muscle and the muscle activity degree is selected, so as to enable the corresponding muscle with high fatigue degree of the eyeball muscle and low activity degree of the eyeball muscle to be exercised more fully.

[0025] Preferably, the data collection method for judging the fatigue degree of the eye is as follows:

[0026] Collecting a dynamic video of the face of the user,

[0027] Extracting the number of frames in which the eyelid covers the eyeball in the face video,

[0028] Counting the number of blinks in a unit time to obtain the blink frequency.

[0029] Eye fatigue is usually manifested in the blink action. The fatigue state of the eye can be obtained in real time by counting the blink frequency of the eye.

[0030] Preferably, the data collection method for determining the blink frequency criterion for judging the eye fatigue state is:

[0031] When the blink frequency of the user is lower than the lower limit of the first range, reflecting that the user's eyes are in a non-fatigued state, the control module controls the detection mode of the eye muscle activity detection module to be turned on, and the activity levels of different eye muscles are obtained as reference for judging the activity levels of different eye muscles when the eyes are fatigued. The activity levels of eye muscles are different when the eye muscles are fatigued, so when the user's eye muscles are detected to be in a non-fatigued state, the activity levels of the eye muscles during this period can be collected as a reference standard.

[0032] Preferably, the data collection method for determining the contraction speed of the eye muscle for judging the activity level of the eye muscle is:

[0033] Collecting dynamic video of the user's eyes moving between specified positioning points,

[0034] Calculating the contraction speed of the eye muscles corresponding to the movement of the eyes.

[0035] The activity level of the eye muscle can be reflected by the contraction speed of the eye muscle. When the activity level is low, the contraction speed of the eye muscle is slow, and when the activity level is high, the contraction speed of the eye muscle is fast. By collecting the speed of the eye following the movement of different positioning points, the contraction speed of the eye muscle can be reflected. This method is easy to operate and has high accuracy.

[0036] Preferably, when the blink frequency of the user is lower than the lower limit of the first range, reflecting that the user's eyes are in a non-fatigued state, the control module collects the variation range of the contraction speed of the eye muscle, and defines the variation range as a predetermined range. When the contraction speed of the eye muscle exceeds the predetermined range, it is determined that the activity level of the eye muscle is lower than the activity level of the specific eye muscle obtained when the eye muscle is in a non-fatigued state.

[0037] Preferably, when the activity level of the specific eye muscle is lower than the activity level of the specific eye muscle obtained when the eye muscle is in a non-fatigued state, the exercise mode corresponding to the specific eye muscle is repeated one or more times, and the exercise sequence of the exercise mode is adjusted to be in the first order. First, the eye muscle with low activity level is strengthened, and the eye muscle exercise is not performed in the same exercise sequence every time, so that when the exercise is stopped due to limited time, the eye muscle with low activity level cannot be exercised or cannot be fully exercised.

[0038] Preferably, the exercise sequence is determined by the contraction speed of the eyeball muscle, wherein the contraction speed of a specific eyeball muscle is the maximum in the contraction speed of the eyeball muscle, and the sequence adjustment of the exercise mode corresponding to the specific eyeball muscle is adjusted to the first position. The exercise sequence of the eyeball muscle is determined according to the degree of activity, and the eyeball muscle with the lowest degree of activity is ranked first. The eyeball muscle with a lower degree of activity is set to the second or third, and the determination of the exercise sequence is sequentially performed from the eyeball muscle with the lowest degree of activity. The eyeball muscle with the highest degree of fatigue or the lowest degree of activity can be exercised in time, thereby effectively relieving the fatigue of the eyeball muscle.

[0039] Preferably, the degree of activity of different eyeball muscles obtained when the user's eyes are in a non-fatigue state is a first degree of activity, and the degree of activity of the eyeball muscle is defined as a second degree of activity when the degree of activity of the eyeball muscle is lower than the first degree of activity.

[0040] Preferably, the degree of activity of the eyeball muscle is obtained by the contraction speed, contraction amount or stretching amount of the eyeball muscle. The degree of activity of the eyeball muscle can be reflected by the contraction speed, contraction amount or stretching amount thereof, for example, the faster the contraction speed, the higher the sensitivity of the eyeball muscle, and accordingly, the degree of activity of the eyeball muscle is higher.

[0041] Preferably, the change of the lighting sequence and / or position of the illuminator constitutes different exercise lighting modes. The present application forms different exercise lighting modes by changing the lighting sequence and / or position of the illuminator. The various changes of the illuminator increase the exercise angle of the eyeball muscle, so that the eye can be fully exercised during the movement.

[0042] Preferably, the illuminator of the exercise lighting mode is set to low CCT light. Preferably, the color temperature of the LED lamp bead is set to 2700K-3000K. Low CCT light has a spectrum that can effectively inhibit the excessive growth of the eye axis, and has obvious advantages in effectively slowing down the occurrence of myopia and relieving eye fatigue.

[0043] Beneficial effects:

[0044] 1. The lamp bead layout range of the desk lamp provided by the present application is wide, and is arranged at the edge of the light emitting surface 110 at 360°, and there are 12 lamp beads, and the adjacent lamp beads are spaced apart by 30°. In the actual exercise process, the movement angle of the eyeball is diversified, that is, the desk lamp of the present application can provide a larger exercise angle. Accordingly, the muscles of the eye can be stretched and contracted at multiple angles, and the muscles, blood vessels and nerves around the eye can also be exercised, thereby effectively regulating the function of the eye muscle.

[0045] 2. The exercise lighting modes of the desk lamp provided by this invention include: a first mode for exercising the medial and lateral rectus muscles; a second mode for exercising the superior and inferior rectus muscles; a third mode for exercising the superior and inferior oblique muscles; and a fourth mode for exercising the extraocular muscles. For different eye muscles, the desk lamp is equipped with modes for exercising the corresponding muscles, including modes for exercising specific eye muscles individually and modes for exercising all eye muscles, ensuring sufficient movement of the eyeballs in the left-right, up-down, and cross directions, thereby allowing the eye muscles to be fully stretched and contracted. Furthermore, this invention first detects the fatigue level of the eye muscles. When the detection result is mild fatigue, the eye muscles are exercised sequentially using the first, second, third, and fourth modes. Mild fatigue indicates that the load on the eye muscles is relatively small, and recovery can be achieved through moderate exercise without the need for additional exercise repetitions or duration. After exercising each eye muscle individually, the multi-directional rotation training in the fourth mode can achieve the purpose of restorative stretching. When experiencing severe fatigue, a muscle activity detection mode is activated to identify eye muscles with low activity levels. These muscles are then targeted for enhanced training to improve the overall effectiveness. Unlike existing technologies, eye muscle training doesn't involve simple repetitive exercises based on fixed patterns. Instead, it involves selectively choosing combinations of training modes tailored to the individual eye muscle fatigue and activity levels. For example, junior high or senior high students often spend long hours doing homework and taking exams, resulting in prolonged close-range eye use, which reduces eye muscle activity. When the detection module detects low activity in the medial rectus muscle, the control module increases the frequency of the corresponding training mode or adjusts the training order. Specifically, the first training mode is increased to provide sufficient exercise for the medial rectus. If low activity is detected in the superior and inferior oblique muscles, the control module increases the frequency of the third training mode and prioritizes it. Furthermore, students face significant academic pressure, typically leaving them little time for exercise. Under pressure, they may become irritable, and prolonged exercise can lead to students stopping before completion. Traditional exercise routines involve repeating exercises twice, but these repetitions are often lengthy, causing students to abandon the exercise midway. Consequently, only the eye muscles corresponding to the earlier exercise routine are typically trained, while those corresponding to later routines are often neglected. This invention effectively solves this problem by assessing the fatigue and activity levels of the eye muscles. It increases the training time for eye muscles with high fatigue and low activity levels, while correspondingly reducing the training time for eye muscles with normal or high activity levels.This allows the overall time to be kept within a shorter range, ensuring that users can complete the entire exercise while also providing sufficient training for the less active eye muscles, ultimately guaranteeing a better eye exercise effect.

[0046] Furthermore, as the position and cycle number of the LED beads in the lighting module change, the eyeballs also move at multiple angles in response to the changes in the LED beads, allowing the eye muscles to be flexibly exercised. In this invention, the alternating movements of the eye muscles can enhance their relaxation and contraction efficiency. Targeted muscle training can quickly relieve eye fatigue and continuously strengthen the eye muscles, thereby stimulating optic nerve responses and accelerating blood circulation in the eyes, ultimately achieving the goal of soothing the eye muscles and eliminating fatigue caused by excessive eye strain. This invention has a significant effect on preventing myopia or slowing the progression of myopia.

[0047] 3. The exercise lighting mode of the desk lamp provided by this invention uses low CCT illumination, specifically, a color temperature of 2700k to 3000k. Under this illumination condition, eye muscle training can protect the user's eyes to the greatest extent. Low CCT illumination has a spectrum that can effectively inhibit excessive axial elongation. This spectrum contains a large amount of deep red and near-infrared light, as well as a very small amount of blue light that is harmful to the human eye. It has significant advantages in effectively inhibiting excessive axial elongation, slowing the onset of myopia, and relieving eye fatigue.

[0048] 4. The desk lamp provided by this invention can match the initial exercise mode based on the eye-related information input by the user, which helps to correctly formulate the exercise mode combination that best suits the user's own state. It can also adjust the exercise mode in real time according to the user's eye muscle activity during use, and exercise the user's eye muscles in a targeted manner. It can also provide feedback on the user's eye information obtained by the detection module, and adjust the subsequent exercise mode to further stretch the less active eye muscles, thereby effectively relieving the user's eye fatigue.

[0056] The following is a detailed explanation with reference to the accompanying drawings.

[0057] Eye information refers to the user's eye movement information, including information on eye fatigue level and eye muscle activity. The combination of training lighting modes refers to the combination of different eye muscle training modes. There are six muscles within the eye socket, collectively known as the extraocular muscles: superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique. The superior rectus is an extraocular muscle attached to the top of the eye, moving the eyeball upwards; the inferior rectus is an extraocular muscle attached to the bottom of the eye, moving the eyeball downwards. The medial rectus is an extraocular muscle attached to the side of the eye closest to the nose, moving the eyeball nasally; the lateral rectus is an extraocular muscle attached to the side of the eye closest to the temporal side, moving the eyeball laterally. The superior oblique is an extraocular muscle originating from the back of the eye socket, passing near the nose, and attaching to the top of the eyeball. The superior oblique causes the eyeball to rotate inwards along its long axis (from front to back) and also controls downward movement of the eyeball. The inferior oblique muscle is an extraocular muscle that originates from the front of the eye socket near the nose and attaches to the bottom of the eyeball. Before attaching to the bottom of the eyeball, the inferior oblique muscle travels outward and backward along the eye socket. The inferior oblique muscle causes the eyeball to rotate outward along the long axis of the eye (from front to back), and it also controls the downward movement of the eyeball.

[0058] Example 1

[0059] This embodiment provides a desk lamp for exercising eye muscles and preventing myopia, such as... Figure 1 As shown, the lamp includes: a lighting module 100 having a plurality of light-emitting elements 120 arranged in a preset shape, configured to have a combination of a plurality of preset exercise lighting modes; an input module 200 for acquiring information related to the user's eye state to match the combination of exercise lighting modes; and a control module 400 disposed on the lamp, the control module 400 being configured to control the lighting module 100 to exercise the user's eyes with a combination of exercise lighting modes adapted to the user's eye state based on the information received by the input module 200, wherein the combination of exercise lighting modes includes one or more of exercise duration, number of cycles, and exercise sequence.

[0060] Preferably, the information related to eye condition refers to information that reflects the user's eye's accommodative function. Preferably, the information related to eye condition refers to information that reflects the user's eye fatigue level. Preferably, the information related to eye condition includes at least the user's age, actual visual acuity, history of wearing glasses, duration of eye use, and type of work. Specifically, the accommodative function of the eyes differs at different age stages. As age increases, the ciliary muscle's ability to contract and relax decreases, and its accommodative power gradually declines. Compared to users with normal vision, nearsighted users have poorer accommodative power. The type of work and the corresponding duration of eye use also significantly affect the user's eye condition. For example, students who read printed books for one hour may experience dry eyes; web designers who work on computers for long periods, facing computer screens for 10 hours or more daily, may experience eye strain, tearing, and other discomfort. Therefore, the combination of training lighting modes needs to be matched based on the acquired information related to the user's eye condition to select a suitable combination of training lighting modes for the user's eyes, thereby achieving the best eye training effect.

[0061] The input module 200 is used to receive information related to eye status input by the user. Preferably, the input module 200 can be a handwriting input tablet, a voice input device, a scanner, etc. Preferably, the input module 200 is communicatively connected to the control module 400. Specifically, the input module 200 is electrically connected to the control module 400. Specifically, the input module 200 is wirelessly connected to the control module 400 or connected via Bluetooth.

[0062] Figures 1 to 5 The desk lamp provided in this embodiment includes at least a lighting module 100, an input module 200, a detection module 300, a control module 400, a support rod 500, and a base 600.

[0063] The lighting module 100 is connected to the base 600 via a support rod 500. Specifically, the first end of the support rod 500 is connected to the lighting module 100 via a connecting assembly. Preferably, the connecting assembly is a pivot assembly. The pivot assembly includes a mounting hole at the first end of the support rod 500 and a rotation shaft in the lighting module 100. Preferably, the lighting module 100 rotates around the connecting assembly so that the light-emitting surface 110 of the lighting module 100 faces the user's face.

[0064] Preferably, the light-emitting element 120 of the lighting module 100 is a lamp bead. Specifically, the light-emitting element 120 can be an LED lamp.

[0065] Preferably, the desk lamp includes a normal lighting mode and an exercise lighting mode for exercising eye muscles.

[0066] Preferably, the lighting module 100 of the desk lamp is configured as a circular light-emitting surface 110. The circular light-emitting surface 110 includes 12 LED beads, which are evenly distributed along the circular edge, and each bead is arranged at a 30° angle. Preferably, the spectrum of the desk lamp is an eye-protecting spectrum. Particularly preferably, the LED beads in the exercise lighting mode are set to low CCT illumination. Specifically, the color temperature of the LED beads is set to 2700K to 3000K. Low CCT illumination can effectively suppress the spectrum of excessive axial elongation of the eye. This spectrum contains a large amount of deep red and near-infrared light and less blue light that is harmful to the human eye, and has significant advantages in effectively suppressing excessive axial elongation of the eye, slowing the onset of myopia, and relieving eye fatigue. Preferably, different lighting sequences and / or positions of the LED beads constitute different exercise lighting modes. Preferably, the exercise lighting modes include at least a first mode for exercising the medial and lateral rectus muscles, a second mode for exercising the superior and inferior rectus muscles, a third mode for exercising the superior and inferior oblique muscles, and a fourth mode for exercising the extraocular muscles.

[0067] Figure 2 This is a diagram illustrating the first mode of exercising the medial and lateral rectus muscles. The exercise involves the leftmost and rightmost LEDs, located at the 3 o'clock and 9 o'clock positions, flashing sequentially. The eyes focus on the lit LEDs. Each LED will remain lit for 1.2 seconds, and this is repeated 20 times. Focusing on the lit LEDs in sequence causes the eyeballs to move from side to side, thus exercising the medial and lateral rectus muscles.

[0068] Figure 3 This is a diagram illustrating the second mode of exercising the superior and inferior rectus muscles. The exercise involves four LEDs located at the 3 o'clock, 6 o'clock, 9 o'clock, and 12 o'clock positions, which flash sequentially in the order of 12 o'clock → 6 o'clock → 3 o'clock → 9 o'clock, with each LED lit for 1.2 seconds, for 10 cycles. After 10 cycles, the four LEDs flash again in the order of 12 o'clock → 6 o'clock → 9 o'clock → 3 o'clock, with each LED lit for 1.2 seconds, for another 10 cycles. The up-and-down eye movements exercise the superior and inferior rectus muscles; therefore, this mode effectively trains both muscles.

[0069] Figure 4 This is a diagram illustrating the third mode of exercising the superior and inferior oblique muscles. The exercise involves four LEDs located at the 2 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock positions, which flash sequentially in the order of 2 o'clock → 10 o'clock → 8 o'clock → 4 o'clock, with each LED lit for 1.2 seconds, for 10 cycles. After 10 cycles, the four LEDs flash again in the order of 2 o'clock → 4 o'clock → 8 o'clock → 10 o'clock, with each LED lit for 1.2 seconds, for another 10 cycles. This eye movement, involving crossing the eyeballs, effectively exercises the superior and inferior oblique muscles; therefore, this mode can effectively train both muscles.

[0070] Figure 5 This is a diagram illustrating the fourth mode of exercising the extraocular muscles. The exercise involves 12 LED beads moving sequentially in the direction of 12 o'clock → 8 o'clock → 4 o'clock → 10 o'clock → 6 o'clock → 2 o'clock → 9 o'clock → 5 o'clock → 1 o'clock → 7 o'clock → 11 o'clock → 3 o'clock. Each LED bead will light up for 1.2 seconds, and this cycle is repeated 5 times. In this mode, the eyeballs move left and right, up and down, and crosswise, fully exercising the extraocular muscles. Specifically, the fourth mode comprehensively exercises the medial rectus, lateral rectus, superior rectus, inferior rectus, superior oblique, and inferior oblique muscles.

[0071] This embodiment collects eye movement information to determine the user's level of eye fatigue.

[0072] Preferably, the eye movement information can be the user's blinking frequency or the proportion of eye closure time per unit time. In this embodiment, the control module 400 extracts the eye closure time per unit time and calculates the proportion of eye closure time within a certain period. Preferably, the method for judging eye fatigue can be based on the PERCLOS standard. This embodiment uses the p80 standard in this method for judgment. p80 refers to the proportion of time in which the eyelid covers more than 80% of the eyeball area. Preferably, the number of frames in which the eyelid covers more than 80% of the eyeball area is the number of frames indicating fatigue.

[0073] Specifically, the detection module 300 collects the user's facial information and sends it to the control module 400. The control module 400 stores the facial recognition algorithm. Preferably, the facial information is a dynamic video of the user's face. After processing the dynamic facial video collected by the detection module 300, the control module 400 obtains the number of frames indicating fatigue where the eyelids cover more than 80% of the eyeball. The control module 400 compares the number of fatigue-indicating frames with the total number of frames to obtain the PERCLOS value, and finally judges the degree of eye fatigue. Preferably, in this embodiment, a PERCLOS value less than 0.1 indicates no fatigue, a PERCLOS value between 0.1 and 0.5 indicates mild fatigue, and a PERCLOS value greater than 0.5 indicates severe fatigue.

[0074] Preferably, the level of eye fatigue can be determined by blinking frequency. The blinking frequency of a normal person when not fatigued is 15-20 times per minute. When a user's eyes are fatigued, their blinking frequency usually increases. In this embodiment, a blinking frequency of 20-30 times per minute is defined as a mild fatigue state, and a blinking frequency greater than 30 times per minute is defined as a severe fatigue state.

[0075] Preferably, the control module 400 is configured to, when the user's blinking frequency is higher than the highest value of the first range, indicating that the user's eyes are in a state of severe fatigue, control the detection module 300 to activate the mode of detecting the activity level of the eye muscles to obtain eye movement information.

[0076] Preferably, the detection module 300 includes a mode for detecting the degree of eye fatigue and a mode for detecting the activity level of the eye muscles. Preferably, the detection module 300 can be an eye movement sensor.

[0077] Specifically, the method for obtaining eye movement information is as follows: the detection module 300 collects eye movement information and sends it to the control module 400. The control module 400 extracts and analyzes the features of the eye movement, and finally obtains the activity level of the extraocular muscles. This embodiment can collect movement information of one eye. For example, the right eye is covered, and the left eye is detected. The detection module 300 has a test panel, which is rectangular. Four positioning points are set at the four corners of the test panel so that the moving object can move between the positioning points, thereby guiding the user's eye movement. In this example, the positioning point at the upper left corner of the test panel is set as C1, the positioning point at the lower left corner is set as C2, the positioning point at the upper right corner is set as C3, and the positioning point at the lower right corner is set as C4. Before the detection starts, the eye is focused on the midpoint of the test panel, and the moving object is at C1. The left eye focuses on the moving object at C1 from the midpoint of the test panel. At this time, the superior rectus muscle and the lateral rectus muscle of the left eye contract, and the eye movement sensor obtains the contraction speed of the superior rectus muscle and the lateral rectus muscle of the left eye. Preferably, the predetermined range of contraction speed is set to 9–10 ms. Preferably, the control module 400 is configured such that when the contraction speed of the superior rectus and lateral rectus muscles of the left eye is detected to be greater than the upper limit of the predetermined range, it indicates that the contraction speed of the superior rectus and lateral rectus muscles of the left eyeball is slow, that is, the activity level of the superior rectus and lateral rectus muscles is low; and so on, the activity level of different extraocular muscles can be obtained. Preferably, the method for obtaining the activity level of extraocular muscles in this embodiment can also perform simultaneous detection of both eyes.

[0078] Preferably, the control module 400 is configured to not activate the exercise lighting mode when it detects that the user's eyes are not in a fatigued state. Preferably, eye movement information of the user is acquired during the period when the user's eyes are not in a fatigued state, as a reference for judging the activity level of different eye muscles when the eyes are fatigued. Specifically, the eye movement information includes the contraction speed of the eye muscles, the amount of contraction or stretching of the eye muscles.

[0079] Preferably, the activity level of different eye muscles acquired when the user's eyes are not fatigued is defined as the first activity level. Preferably, when the contraction speed of the eye muscles exceeds the upper limit of a predetermined range, the corresponding activity level of the eye muscles is defined as the second activity level. The second activity level indicates that the contraction speed of the eye muscles is lower than the normal contraction speed of the eye muscles, i.e., the activity level is lower.

[0080] Preferably, the different ocular muscles include the medial and lateral rectus muscles, the superior and inferior rectus muscles, and the superior and inferior oblique muscles. In this embodiment, the first activity level indicates that the ocular muscles are in an active state, and the contraction speed of the corresponding muscles during eye movements is within a normal predetermined range.

[0081] Preferably, the control module 400 is configured to perform eye muscle exercises on the user using a first combination of training lighting modes when the user's blinking frequency is within a first range, indicating that the user's eyes are in a state of mild fatigue. Specifically, the first combination of training lighting modes consists of: a first mode, a second mode, a third mode, and a fourth mode performed sequentially.

[0082] Preferably, the control module 400 is configured such that when the user's blinking frequency exceeds the highest value of the first range, indicating severe eye fatigue, the control detection module 300 activates to acquire the user's eye movement information as a basis for selecting a combination of exercise lighting modes. Preferably, the control module 400 is configured such that when the user's blinking frequency exceeds the highest value of the first range, indicating severe eye fatigue, the control detection module 300 enters a detection mode for the activity level of the eye muscles and generates an information on the activity level of the eye muscles to select a combination of exercise lighting modes that matches the level of muscle activity.

[0083] According to a preferred embodiment, the control mode 400 is configured to increase the number of times or the duration of the exercise lighting mode corresponding to the exercise of the specific muscle when the activity level of a specific muscle in the eye muscles is detected to be at a second activity level. The specific muscle refers to at least a portion of the eye muscles detected to be at the second activity level, including one or more of the medial rectus, lateral rectus, superior rectus, inferior rectus, superior oblique, and inferior oblique muscles.

[0084] Preferably, the control module 400 is configured to turn off the exercise lighting mode when it detects that the user's eye muscles are not fatigued, i.e., when the user does not need to perform eye muscle exercises. For example, the user's PERCLOS value is less than 0.1.

[0085] Preferably, the control module 400 is configured to perform eye muscle exercises on the user using a first combination of exercise lighting modes when mild eye muscle fatigue is detected. Specifically, the first combination of exercise lighting modes consists of: a first mode, a second mode, a third mode, and a fourth mode performed sequentially. For example, if the user's PERCLOS value is 0.3, the combination of exercise lighting modes of the desk lamp is: first mode → second mode → third mode → fourth mode.

[0086] Preferably, the control module 400 is configured to, when detecting severe eye muscle fatigue in the user, activate the eye muscle activity detection mode; when detecting a second level of activity in a specific eye muscle, increase the number of cycles of the exercise lighting mode corresponding to the exercise of that specific muscle and / or adjust the exercise sequence. For example, when the activity of the superior and inferior rectus muscles is detected to be at the second level, exercise is performed using a combination of first mode → second mode → second mode → third mode. When the activity of the medial rectus, lateral rectus, superior oblique, and inferior oblique muscles is detected to be at the second level, exercise is performed using a combination of first mode → first mode → second mode → third mode → third mode, and so on. When the activity of a specific muscle is at the second level, the number of cycles corresponding to the exercise of that specific muscle is increased.

[0087] Preferably, the control module 400 is configured to, when detecting a second level of activity in a specific muscle within the eye muscles, prioritize the training sequence of the training lighting mode corresponding to the training of that specific muscle. The training lighting modes are ordered according to muscle activity levels; the lower the muscle activity level, the higher the order of the corresponding training mode. For example, when the activity level of the superior and inferior rectus muscles is detected as the second level, training is performed using a combination of second mode → second mode → first mode → third mode. When the contraction velocity of the superior and inferior rectus muscles is detected to be 11 ms, and the contraction velocity of the superior and inferior oblique muscles is detected to be 10.5 ms, the control module 400 trains the eye muscles using the second mode → second mode → third mode → third mode → first mode.

[0088] Preferably, the control module 400 can be a processor or a microcontroller.

[0089] Example 2

[0090] The content that is repeated in this embodiment and in embodiment 1 will not be repeated.

[0091] This embodiment uses a ninth-grade student as an example. When the student is doing homework, the desk lamp is turned on in normal lighting mode. When eye muscle exercises are needed, the normal lighting mode is switched to exercise lighting mode. When the desk lamp is in exercise lighting mode, the light-emitting surface 110 of the desk lamp is adjusted to be perpendicular to the student's line of sight. The preferred distance between the light-emitting surface 110 and the student's face is between 30cm and 40cm. The eye conditions of people with normal vision and people with myopia are different. People with normal vision generally have good muscle and lens accommodation abilities, but excessive use of the eyes can also lead to eye fatigue. Long-term excessive use of the eyes can weaken the eye's self-accommodation ability, eventually causing the axial length to elongate and leading to myopia.

[0092] In this embodiment, the control module 400 determines the user's eye fatigue level based on the eye condition information input by the user, and then matches a suitable exercise lighting mode for the user.

[0093] The criteria for classifying eye fatigue differ depending on the user group. For those whose primary visual input is paper, the classification is as follows: 1-3 hours of screen time is mild fatigue, 3-6 hours is moderate fatigue, and over 6 hours is severe fatigue. For those whose primary visual input is electronic devices, the classification is as follows: 1-2 hours of screen time is mild fatigue, 2-4 hours is moderate fatigue, and over 4 hours is severe fatigue.

[0094] Preferably, the control module 400 is configured to provide eye exercises to the user using a first training lighting mode combination when the user's eye fatigue level is mild. Preferably, the first training lighting mode combination is performed sequentially as follows: First Mode → Second Mode → Third Mode → Fourth Mode. For example, if a student's visual acuity is 5.0 in both eyes and they have been reading and writing for 2 hours, they input their age, visual acuity, and daily screen time into the input module 200. After receiving the information from the input module 200, the control module 400 confirms that the student's eyes are mildly fatigued and controls the lighting module 100 to provide eye exercises to the student using the first training lighting mode combination.

[0095] Preferably, the control module 400 is configured to perform eye exercises on the user using a second training lighting mode combination when the user's eye fatigue level is moderate. Preferably, the second training lighting mode combination is: first mode → second mode → third mode → fourth mode, performed sequentially and repeated once. Specifically, the second training lighting mode combination is: first mode → second mode → third mode → fourth mode; the first mode → second mode → third mode → fourth mode are performed sequentially. For example, if a student's reading and writing time is 5 hours, after receiving information from the input module 200, the control module 400 confirms that the student's eyes are moderately fatigued, and the control module 400 controls the lighting module 100 to perform eye exercises on the student using the second training lighting mode combination.

[0096] Preferably, the control module 400 is configured to perform eye exercises on the user using a third training lighting mode combination when the user's eye fatigue level is severe. Preferably, the third training lighting mode combination is: first mode → second mode → third mode → fourth mode, performed sequentially and repeated twice. Specifically, the second training lighting mode combination is: first mode → second mode → third mode → fourth mode; first mode → second mode → third mode → fourth mode; first mode → second mode → third mode → fourth mode, performed sequentially. For example, if a student's reading and writing time is 7 hours, after receiving information from the input module 200, the control module 400 confirms that the student's eyes are severely fatigued, and the control module 400 controls the lighting module 100 to perform eye exercises on the student using the third training lighting mode combination.

[0097] Preferably, the eye muscle activity state is determined based on the eye movement reaction time during eye exercises, and the combination of exercise lighting modes is adjusted to exercise the corresponding eye muscles of the user. Preferably, the eye muscle activity state refers to the relaxation state of the eye muscles during eye exercises. Specifically, the eye muscle activity state reflects the exercise effect. Preferably, the eye muscle activity state can be judged by detecting the activity level of the eye muscles. Eye movement reaction time refers to the time it takes for the eye to react to movement. Preferably, the relaxation state is reflected by the contraction speed of the eye muscles. Since eye movements require the participation of multiple extraocular muscles, the eye movement reaction time can reflect the extraocular muscle activity state. The predetermined range of contraction speed is the time required for eye movements controlled by a specific muscle group with normal eye muscle activity.

[0098] During eye exercises, the detection module 300 detects the user's eye muscle activity. Preferably, the detection module 300 is an eye movement detection device. Specifically, the detection module 300 can be a camera sensor. Preferably, the detection module 300 is communicatively connected to the control module 400. Specifically, the detection module 300 is electrically connected to the control module 400. Specifically, the detection module 300 is wirelessly connected to the control module 400 and via Bluetooth.

[0099] Preferably, the activity level of the eye muscles is detected by comparing the reaction time of the eye muscles to the light source 120 in the corresponding training lighting mode with a predetermined range of contraction speed to determine the activity level of the eye muscles. Preferably, the predetermined range of contraction speed is the time required for muscle movement controlled by a specific eye muscle in a non-fatigue state. When the reaction time of the eye muscles to the light source 120 in the corresponding training lighting mode is less than the minimum value of the predetermined range of contraction speed and / or within the predetermined range of contraction speed, it indicates that the fatigue of the corresponding eye muscles trained in this mode has been relieved, and their activity level is high; when the reaction time of the eye muscles to the light source 120 in the corresponding training lighting mode is greater than the maximum value of the predetermined range of contraction speed, it indicates that the fatigue of the corresponding eye muscles trained in this mode has not been sufficiently relieved, and their activity level is low.

[0100] Preferably, the control module 400 is configured to control the exercise lighting mode combination to enter the next mode of eye muscle exercise when the reaction time of the eye muscles in the corresponding exercise lighting mode to the light source 120 is less than and / or equal to a predetermined range of contraction speed. For example, for the superior rectus and inferior rectus muscles in the 7th cycle of the second mode, if the reaction time of the superior rectus and inferior rectus muscles obtained by the detection module 300 is less than the minimum value of the predetermined range of contraction speed, the control module 400 ends the exercise of the superior rectus and inferior rectus muscles and enters the third mode to exercise the superior oblique and inferior oblique muscles.

[0101] Preferably, the control module 400 is configured to increase the number of cycles of the corresponding eye muscle mode when the reaction time of the eye muscle in the corresponding training lighting mode to the light source 120 is greater than the maximum value of the contraction speed within a predetermined range. For example, for the superior and inferior rectus muscles in the 10th cycle of the second mode, if the reaction time of the superior and inferior rectus muscles detected by the detection module 300 is greater than the maximum value of the contraction speed within a predetermined range, the control module 400 controls the lighting module 100 to increase the number of cycles of the second mode to continue training the superior and inferior rectus muscles. Specifically, the number of cycles can be increased by 5 to 20.

[0102] Preferably, the desk lamp further includes a prompting module to allow the user to obtain results regarding eye exercises. Preferably, the prompting module is communicatively connected to the control module 400. Specifically, the prompting module is electrically connected to the control module 400. The prompting module is connected to the control module 400 via Bluetooth or wirelessly. Preferably, the prompting module can be an audio prompting module. Preferably, the prompting module can be a light prompting module. Specifically, the prompting module is a speaker.

[0103] When a user performs eye muscle exercises, the detection module 300 acquires the user's eye recovery results. Preferably, the detection module 300 acquires images of the user's eye movements to determine the degree of eye fatigue. After acquiring the user's eye information, the detection module 300 sends it to the control module 400.

[0104] Preferably, the control module 400 controls the prompting module to issue corresponding sound prompts based on the eye recovery results. Preferably, the prompting module can also be a mobile terminal. For example, the prompting module can be a mobile phone, tablet, or computer.

[0105] Preferably, the control module 400 is configured to stop the exercise lighting mode of the lighting module 100 when the eye recovery result after exercise is no fatigue. When the student performs the first exercise, and the control module 400 obtains that the student's eye recovery result is no fatigue, it controls the lighting module 100 to turn off the exercise lighting mode.

[0106] Preferably, the control module 400 is configured to issue a first prompt message when the eye recovery result after exercise is mild fatigue, wherein the first prompt message is to increase the rest time for the eyes.

[0107] Preferably, the control module 400 is configured to issue a second prompt message when the eye recovery result after exercise is moderate fatigue, wherein the second prompt message is to increase the duration of eye muscle exercise.

[0108] Preferably, the control module 400 is configured such that when the eye recovery result after exercise is severe fatigue, the control prompt module issues a third prompt message, wherein the third prompt message is to increase the eye muscle exercise for a second duration, the second duration being greater than the first duration.

[0109] Example 3

[0110] This embodiment is for people with myopia. The degree of myopia in this embodiment is classified according to existing myopia grading standards. Preferably, the degree of myopia includes a first visual acuity level representing mild myopia, a second visual acuity level representing moderate myopia, and a third visual acuity level representing severe myopia. Specifically, the first visual acuity level typically refers to myopia of 300 degrees or less. The second visual acuity level refers to myopia between 300 and 600 degrees; and the third visual acuity level typically refers to myopia exceeding 600 degrees.

[0111] Preferably, the combination of training lighting modes includes at least a first mode for exercising the medial and lateral rectus muscles, a second mode for exercising the superior and inferior rectus muscles, a third mode for exercising the superior and inferior oblique muscles, and a fourth mode for exercising the extraocular muscles. The higher the degree of myopia, the worse the accommodative ability of the eye muscles, and therefore the more frequent the eye muscle exercises are needed to relieve eye strain.

[0112] Preferably, the control module 400 is configured to control the order and number of cycles of the lighting modes of the LED beads according to the user's vision level. For example, when an 18-year-old with myopia of 500 degrees uses the exercise lighting mode, the control module 400 determines that the user has a second vision level, and controls the exercise lighting mode combination of the lighting module 100 as follows: Mode 1 → Mode 2 → Mode 3 → Mode 4 → Mode 1 → Mode 2 → Mode 3 → Mode 4. Furthermore, in each lighting mode, the number of cycles in Mode 1 increases from 20 to 40, the number of cycles in Modes 2 and 3 increases from 10 to 20, and the number of cycles in Mode 4 increases from 5 to 10. If the user is a 12-year-old child with myopia of 100 degrees, the child's vision level is determined to be low myopia, and the exercise lighting mode combination is controlled as follows: Mode 1 → Mode 2 → Mode 3 → Mode 4.

[0113] During training, if the reaction time of eye movements controlled by the user's superior and inferior oblique muscles exceeds a predetermined range of contraction speed, the activity level of these muscles is determined to be low. In the next training session, the control module 400 increases the number of cycles in the third mode from 10 to 20. If high activity is detected in a specific eye muscle, the number of cycles for that corresponding eye muscle training mode is reduced. For example, if the reaction time of eye movements controlled by the user's medial and lateral rectus muscles is detected to be below a predetermined range of contraction speed, the activity level of these muscles is determined to be high. In the next training session, the control module 400 reduces the number of cycles in the first mode from 20 to 10.

[0114] Preferably, when the PERCLOS value of the user obtained by the control module 400 is less than 0.1 and the activity level of each eye muscle is at a high level, it is determined that the user's eye fatigue has been sufficiently relieved, and the control lamp stops the exercise lighting mode.

[0115] Preferably, the control module 400 is configured such that when the detection result of the detection module 300 does not match the information input by the user in the input module 200, the control prompt module displays feedback information that is consistent or contradictory between the two. For example, if the user provides that they will study videos for 1 hour today, but the detection module 300 detects that the user's fatigue level is severe, the control module determines that the two pieces of information are contradictory and prompts the user on the mobile phone, allowing the user to adjust the exercise duration according to their eye fatigue level.

[0116] Compared with existing eye training devices, the desk lamp provided by this invention has the advantages of a wider range of lamp bead layout, providing a greater range of training angles. When using the desk lamp for training, users can move their eyeballs at multiple angles, meaning the eye rotation angle is large, allowing for better stretching and contraction of the eye muscles. Although it cannot improve the vision of users who are already nearsighted, the desk lamp provided by this invention can ensure that the eye muscles of users who use their eyes for extended periods receive sufficient exercise, effectively relieving eye fatigue and slowing the progression of myopia.
