Description

Technical Field

[0001] This invention relates to the field of intelligent lighting technology, specifically to a method and device for processing red light to protect the eyes of a fully intelligent reading desk lamp. Background Technology

[0002] With the increasing academic burden on teenagers and the widespread use of electronic devices, prolonged close-range use of the eyes has led to a continuous rise in the incidence of myopia, making vision health a focus of attention for the whole society. Studies have shown that repeated low-intensity red light exposure can effectively control the progression of myopia in children and adolescents. 650nm red light can promote retinal cell repair and regeneration, improve blood circulation in the fundus, and thus relieve symptoms of eye fatigue such as dryness and soreness.

[0003] Based on the above principles, some eye-protection desk lamps integrating red light sources have appeared on the market. However, existing red light eye-protection desk lamp technology still has the following significant shortcomings: First, the red light illumination strategy is simplistic and lacks personalized adaptation. Existing desk lamps typically use fixed illumination parameters (such as fixed power and fixed duration), failing to dynamically adjust according to individual differences such as the user's real-time eye usage status and fatigue level.

[0004] Secondly, there is a lack of intelligent coordination between red light illumination and reading lighting. Current solutions often involve simply switching one on or manually switching the other between the red light source and the main lighting source, failing to achieve intelligent coordinated control of reading lighting during red light eye protection illumination—for example, automatically adjusting the lighting color temperature to reduce blue light content and appropriately reducing brightness to minimize visual stimulation. This negatively impacts the user experience and eye protection efficiency.

[0005] Third, there is a lack of multi-dimensional perception and comprehensive assessment of eye use status. Existing technologies mainly rely on simple timing triggers and distance detection, failing to comprehensively utilize multi-dimensional data such as ambient light, eye use duration, blinking frequency, and sitting posture to fully assess the user's eye fatigue level, making it difficult to achieve precise red light eye protection intervention.

[0006] To address the shortcomings of the existing technologies, there is an urgent need for a fully intelligent reading lamp red light eye protection solution that can achieve multi-dimensional perception of eye use status, accurate assessment of fatigue, adaptive adjustment of red light irradiation strategy, intelligent coordination between red light and lighting, and integrated multiple safety monitoring functions. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this invention is to provide a method and device for processing red light to protect the eyes of a fully intelligent reading desk lamp, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, a specific embodiment of the present invention provides a method for processing red light to protect the eyes of a fully intelligent reading desk lamp, comprising the following steps: S1. Collect multi-dimensional eye use status data of the user by using multiple sensors installed on the desk lamp. The multi-dimensional eye use status data includes at least the ambient light intensity, the distance between the user's eyes and the red light emitting surface of the desk lamp, the user's facial image, and the continuous reading time. S2. Input the multi-dimensional eye use status data collected in step S1 into a preset eye fatigue assessment model to calculate the current user's eye fatigue index. ; S3, based on the fatigue index Adaptive generation of red light eye protection irradiation strategy: when Do not activate red light eye protection during this time; At this time, the first level of red light eye protection mode is activated, controlling the red light source to output the first light power. First irradiation duration ; when At this time, the second-level red light eye protection mode is activated, controlling the red light source to output at the second light power. Second irradiation duration ,in Furthermore, the output power P of the red light source always does not exceed a preset safety threshold. Duration of a single irradiation Not exceeding the preset maximum safe duration; S4. During the red light eye protection irradiation period, the reading light source of the control lamp is switched from the standard reading mode to the collaborative eye protection mode, the color temperature of the reading light source is adjusted to the preset collaborative color temperature value, and the light intensity is reduced to a preset percentage of the standard intensity. S5. During the red light eye protection irradiation process, the safety parameters are monitored in real time. When the safety parameters are abnormal, the red light irradiation is automatically paused and a prompt is issued. The safety parameters include at least the distance between the user's eyes and the red light emitting surface and the red light emitting power.

[0009] In addition, the method and device for processing red light to protect the eyes of a fully intelligent reading desk lamp as proposed above in this application may also have the following additional technical features: In one embodiment of this application, the calculation formula for the eye fatigue assessment model in step S2 is as follows:

[0010] in, For continuous reading time, The preset maximum continuous reading time threshold; Ambient light intensity and standard reading illuminance The absolute value of the deviation; The frequency of blinking. The preset standard blinking frequency; The degree of deviation from sitting posture. To preset a safe sitting posture distance threshold; These are the weighting coefficients, and .

[0011] In one embodiment of this application, the preset coordinated color temperature value in step S4 is 2700K to 3500K; after the red light irradiation ends, the reading illumination source gradually restores to the color temperature and light intensity before irradiation, and the restoration process adopts a gradual change method with a gradual change duration of 5 to 10 seconds.

[0012] In one embodiment of this application, the safety monitoring in step S5 further includes: automatically pausing the red light irradiation timer when the user's eyes are closed or their face deviates from the direction of the red light irradiation, and resuming the timer after the user returns to normal; the preset safe distance range is 30cm to 50cm; the preset maximum safe duration is 3 minutes; the frequency of red light irradiation per day does not exceed 2 times, and the interval between two adjacent irradiations is not less than 4 hours.

[0013] In one embodiment of this application, step S6 is further included: based on the fatigue assessment results of step S2 and the execution status of red light irradiation, eye behavior guidance information is generated and fed back to the user via voice or display; the eye behavior guidance information includes: issuing a rest reminder when the continuous reading time reaches a preset rest threshold, issuing a posture correction prompt when the sitting posture deviation exceeds a safety threshold, and issuing a distant relaxation prompt after the red light eye protection irradiation ends.

[0014] A fully intelligent reading desk lamp with red light eye protection device includes: a lamp body assembly comprising a base, a support rod, and a lamp head, wherein the lamp head contains a reading illumination source and a red light eye protection source; a sensor assembly comprising an ambient light sensor, a distance sensor, and a camera, all disposed on the lamp head; a timing module for accumulating the user's continuous reading time and red light exposure time; a storage module for storing the user's historical eye usage data and preset control parameters; and a control module electrically connected to the reading illumination source, the red light eye protection source, the sensor assembly, the timing module, and the storage module, and configured to execute the method described herein.

[0015] In one embodiment of this application, the red light eye-protection light source adopts a semiconductor laser diode or LED light source with a center wavelength of 650nm±10nm, and the reading illumination light source adopts full-spectrum LED beads.

[0016] In one embodiment of this application, the ranging sensor is an ultrasonic ranging sensor or an infrared ranging sensor, and the camera is used to capture user facial images to identify eye status and sitting posture.

[0017] In one embodiment of this application, a voice module and a display module are further included, which are electrically connected to the control module respectively. The voice module is used to broadcast eye use behavior guidance information, and the display module is used to display eye use status information and guidance information.

[0018] In one embodiment of this application, a communication module is further included, which is electrically connected to the control module and is used to interact with an external terminal device to transmit the user's eye status data and red light irradiation records.

[0019] The advantages of this invention compared to existing technologies are: (1) Through multi-dimensional sensor data fusion and fatigue assessment model, it can adaptively generate graded red light irradiation strategy according to the user's real-time eye use status (including multiple dimensions such as eye use duration, ambient light, blinking frequency, sitting posture, etc.), realizing personalized eye care from "fixed parameters, uniformity" to "different for each person, dynamic adjustment", which significantly improves the accuracy and effectiveness of eye care intervention.

[0020] (2) During red light irradiation, the color temperature of the reading light is automatically adjusted to the low blue light synergistic color temperature value (2700K~3500K), and the light intensity is appropriately reduced. After the red light irradiation ends, it is smoothly restored in a gradual manner, realizing the intelligent synergistic cooperation between red light eye protection and reading light. This ensures the eye protection effect of red light irradiation and reduces the visual discomfort of users during red light irradiation.

[0021] (3) By comprehensively utilizing ambient light sensors, distance sensors, cameras and timing modules, the user's eye status is fully perceived from multiple dimensions such as ambient light, eye distance, blink frequency, eye duration and sitting posture. By constructing a fatigue assessment model that includes multi-factor weighted fusion, the user's eye fatigue is accurately quantified, providing a reliable data foundation for precise eye care intervention.

[0022] (4) Multiple safety mechanisms are set up, including real-time power monitoring, real-time distance monitoring, irradiation frequency control, interval time control, eye-closed detection and facial deviation detection, to ensure that the power of red light irradiation entering the eye, single duration, daily frequency and interval time all meet the safety standards of medical consensus. When an abnormal state is detected, the irradiation will be automatically paused and a prompt will be issued, making it safe and reliable to use.

[0023] (5) By actively guiding users to use their eyes scientifically through fatigue assessment results, reminding them to rest, correct their posture, and relax by looking into the distance at appropriate times, a complete closed-loop eye protection system of "monitoring → assessment → intervention → guidance" is formed, which helps to cultivate good eye habits in users.

[0024] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1 This embodiment provides a fully intelligent reading desk lamp red light eye protection device and a red light eye protection method implemented based on the device. Combined with... Figures 1 to 6 As shown, the processing device includes a lamp body assembly, a control module 4, a storage module 5, a timing module 6, and a sensor assembly. The lamp body assembly includes a base 1, a support rod 2, and a lamp head 3. One end of the support rod 2 is fixedly connected to the base 1, and the other end of the support rod 2 is connected to the lamp head 3, used to support the lamp head 3 above or in front of the reading area. The lamp head 3 is equipped with a reading illumination source 10 and a red light eye-protection source 11. The reading illumination source 10 emits light towards the reading table or reading area, and the red light emitting surface of the red light eye-protection source 11 is positioned towards the area where the user's eyes are located, so as to provide red light eye protection illumination to the user's eyes when the safe distance condition is met.

[0030] The sensor assembly includes an ambient light sensor 12, a distance sensor 13, and a camera 14, all of which are mounted on the lamp head 3. The ambient light sensor 12 is used to collect the ambient light intensity in the user's reading area; the distance sensor 13 is used to detect the distance between the user's eyes and the red light emitting surface of the red light eye-protection light source 11; and the camera 14 is used to capture images of the user's face for the control module 4 to identify the user's eye state, facial orientation, and sitting posture. The timing module 6 is used to accumulate the user's continuous reading time and red light irradiation time. The storage module 5 is used to store the user's historical eye usage data and preset control parameters, which may include fatigue thresholds. , First output power Second output power First duration Second duration Red light output power safety threshold The control module 4 is electrically connected to the reading light source 10, the red light eye protection light source 11, the ambient light sensor 12, the distance sensor 13, the camera 14, the timing module 6, and the storage module 5, respectively. It is used to receive data collected by the sensor components and the timing module 6, and control the reading light source 10 and the red light eye protection light source 11 to work according to the preset control logic.

[0031] When in use, the user turns on the desk lamp and begins reading. The reading light source 10 initially operates in standard reading mode, providing regular illumination to the reading area. The control module 4 collects ambient light intensity via ambient light sensor 12, distance between the user's eyes and the red light source via distance sensor 13, and facial images via camera 14. The timing module 6 then accumulates the continuous reading time. After processing by the control module 4, the facial images captured by camera 14 provide information such as blink frequency, eye closure status, facial orientation, and posture deviation. The posture deviation can be determined based on facial position, facial angle, or the positional shift of the eyes relative to a preset reading posture.

[0032] Control module 4 inputs the above-mentioned multi-dimensional eye use status data into a preset eye fatigue assessment model to calculate the current user's eye fatigue index. Multi-dimensional eye use data includes at least ambient light intensity, the distance between the user's eyes and the red light source of the desk lamp, the user's facial image, and continuous reading time. Control module 4 uses a fatigue index... Red light eye protection irradiation strategy: When If the system determines that the user's current eye fatigue level is low, red light eye protection will not be activated temporarily, and the reading light source will maintain standard reading mode. At that time, the first-level red light eye protection irradiation mode is activated, and the red light eye protection light source 11 is controlled to output light at the first power. First irradiation duration ;when At this time, the second-level red light eye protection irradiation mode is activated, and the red light eye protection light source 11 is controlled to output light at the second power. Second irradiation duration ,in , Therefore, red light irradiation is not mechanically executed according to fixed parameters, but is adjusted in stages according to the user's current level of eye fatigue.

[0033] During red light eye protection illumination, control module 4 simultaneously controls the reading light source 10 to switch from standard reading mode to collaborative eye protection mode. In collaborative eye protection mode, the color temperature of the reading light source 10 is adjusted to a preset collaborative color temperature value, and the light intensity is reduced to a preset percentage of the standard intensity. Thus, when the red light eye protection light source 11 illuminates with red light, the reading light source 10 no longer maintains a high color temperature or strong brightness as standard illumination, but instead uses a softer illumination state in conjunction with the red light illumination, reducing visual stimulation caused by excessively strong reading illumination or color temperature mismatch during red light illumination.

[0034] During red light eye protection irradiation, the control module 4 monitors safety parameters in real time. These parameters include at least the distance between the user's eyes and the red light emitting surface, as well as the red light emission power. Specifically, the distance sensor 13 continuously feeds back the distance detection results to the control module 4, which then determines whether the distance between the user's eyes and the red light emitting surface is within a preset safe distance range. Simultaneously, the control module 4 monitors the red light emission power based on the drive control signal or power feedback signal for the red light eye protection light source 11. If the distance is too close, too far, or the red light emission power exceeds a preset safety threshold, the control module will take appropriate action. If any safety parameters are abnormal, the control module 4 will automatically pause the red light irradiation of the red light source 11 and issue a warning. The output light power P of the red light source 11 will never exceed the preset safety threshold. Duration of a single irradiation The red light irradiation process is subject to both power and time limitations, ensuring that the maximum safe duration is not exceeded.

[0035] In this embodiment, the red light eye protection processing method includes the following complete workflow: First, the control module 4 controls the reading illumination source 10 to enter the standard reading mode, and collects multi-dimensional eye use status data of the user through the ambient light sensor 12, the distance sensor 13, the camera 14, and the timing module 6; Second, the control module 4 calculates the fatigue index based on the ambient light intensity, the distance between the user's eyes and the red light emitting surface, the user's facial image, and the continuous reading time. Secondly, control module 4 according to and , The comparison results determine whether to activate red light illumination and what level of red light eye protection mode to activate. Then, during the illumination of the red light eye protection source 11, the reading light source 10 is controlled to switch to the collaborative eye protection mode simultaneously. Finally, throughout the entire red light illumination process, safety parameters such as distance, power, and illumination duration are continuously monitored. If any abnormality is detected, illumination is paused and the user is notified. Through the above process, the device can achieve closed-loop processing of eye use status acquisition, fatigue assessment, red light illumination level control, reading light collaborative control, and safety monitoring.

[0036] Example 2 This embodiment is basically the same as embodiment 1 in structure and working principle, the difference being that this embodiment further limits the calculation method of the eye fatigue assessment model.

[0037] Control module 4 calculates the fatigue index according to the following formula. :

[0038] in, For continuous reading time, The preset maximum continuous reading time threshold; Ambient light intensity and standard reading illuminance The absolute value of the deviation; The frequency of blinking. The preset standard blinking frequency; The degree of deviation from sitting posture. To preset a safe sitting posture distance threshold; These are the weighting coefficients, and .

[0039] Specifically, continuous reading time The ambient light intensity is accumulated by the timing module 6 and used to reflect the time factor of continuous close-range eye use by the user; the ambient light intensity is collected by the ambient light sensor 12 and compared with the standard reading illuminance by the control module 4. By comparison, the absolute value of the deviation is obtained. This is used to reflect the degree to which the current reading lighting environment deviates from the standard reading lighting conditions; blink frequency. The user's facial image captured by camera 14 is obtained through eye state recognition. When the user focuses on reading for a long time and the blinking frequency decreases, the formula ( The corresponding fatigue contribution increases; sitting posture deviation... The facial image captured by camera 14 is combined with the distance information from distance sensor 13 to determine the degree of deviation of the user's head or eyes from the preset safe reading posture.

[0040] Control module 4 calculates the fatigue index. Afterwards, With threshold , A comparison was made to generate the red light eye protection irradiation strategy of Example 1. Because this model simultaneously considers continuous reading time, lighting environment deviation, blink frequency, and posture deviation, it avoids activating red light irradiation based solely on a single timing result, ensuring that the irradiation level of the red light eye protection light source 11 matches the user's actual eye usage status. Weighting coefficients The data is stored in storage module 5 and can be configured based on the user's historical eye usage data or preset control parameters, but the sum of all weighting coefficients is 1 to ensure the fatigue index is maintained. The comprehensive evaluation relationship is clear.

[0041] Example 3 This embodiment is basically the same as the structure and working principle of embodiment 1. The difference is that this embodiment further defines the collaborative control method of reading light source 10 and red light eye protection light source 11 as well as the red light irradiation safety control method.

[0042] During red light eye protection illumination, the control module 4 adjusts the color temperature of the reading light source 10 to a preset coordinated color temperature value of 2700K to 3500K, and reduces the light intensity of the reading light source 10 to a preset percentage of the standard intensity. This preset percentage is stored in the storage module 5 and is recalled by the control module 4 when entering the coordinated eye protection mode. By lowering the color temperature and appropriately reducing the light intensity, the reading light source 10 creates a softer reading lighting state during red light illumination, avoiding the increase in visual stimulation caused by the red light eye protection source 11 still having higher color temperature or stronger brightness illumination when it is working.

[0043] After the red light irradiation ends, the control module 4 controls the reading light source 10 to gradually restore its color temperature and light intensity to the state before irradiation. The restoration process is gradual, with a duration of 5-10 seconds. Specifically, the control module 4 records the color temperature and light intensity of the reading light source 10 before the red light irradiation begins. After the red light eye-protection light source 11 stops irradiating, it gradually adjusts the reading light source 10 from the collaborative eye-protection mode back to its pre-irradiation state according to the preset gradual duration, rather than switching instantaneously. This gradual restoration process can reduce the impact of sudden changes in brightness and color temperature on the user's visual experience.

[0044] In terms of safety control, the control module 4 limits the distance between the user's eyes and the red light emitting surface to a preset safe distance range of 30cm to 50cm. When the distance sensor 13 detects that the distance between the user's eyes and the red light emitting surface is less than 30cm or greater than 50cm, the control module 4 automatically pauses the illumination of the red light eye protection light source 11 and notifies the user to adjust their posture or distance through a prompt. The maximum safe duration of a single red light illumination is 3 minutes. The timing module 6 times each red light illumination. When the duration of a single illumination reaches 3 minutes, the control module 4 stops the operation of the red light eye protection light source 11. The control module 4 also limits the daily red light illumination frequency based on the red light illumination execution status recorded in the storage module 5. The daily red light illumination frequency does not exceed 2 times, and the interval between two adjacent illuminations is not less than 4 hours. If the user triggers the red light eye protection illumination condition again before the interval time is met, the control module 4 does not start the red light eye protection light source 11 and issues a corresponding prompt.

[0045] Furthermore, during the red light eye protection illumination process, camera 14 continuously captures images of the user's face, and control module 4 identifies whether the user's eyes are closed and whether the face deviates from the direction of red light illumination based on the facial images. When it is detected that the user's eyes are closed or the face deviates from the direction of red light illumination, control module 4 automatically pauses the red light illumination timer and pauses or stops the red light eye protection light source 11 illumination; after camera 14 detects that the user's eyes are back in a normal open state and the face orientation has returned to the direction of red light illumination, control module 4 resumes the red light illumination timer and resumes illumination. Through the joint monitoring of distance, power, duration, frequency, interval time, closed eye state, and face orientation, red light eye protection illumination can be performed under preset safety conditions.

[0046] Example 4 This embodiment is basically the same as the structure and working principle of embodiment 1. The difference is that this embodiment further defines the red light eye protection light source 11, the reading light source 10, the sensor components, and the user feedback and data interaction structure.

[0047] The red light eye-protection light source 11 uses a semiconductor laser diode or LED light source with a center wavelength of 650nm±10nm. When using the red light eye-protection light source 11 in this wavelength band, the control module 4 adjusts its output power through the drive circuit, and combines it with the fatigue index in Examples 1 to 3. The system implements graded illumination control based on safety parameters. The reading light source 10 uses full-spectrum LED beads to provide reading illumination in both standard reading mode and collaborative eye protection mode. The reading light source 10 and the red light eye protection source 11 can be spaced apart within the lamp head 3, with both emitting light towards the user's area. The reading light source 10 primarily covers the reading desktop, while the red light eye protection source 11 primarily faces the area where the user's eyes are located.

[0048] The ranging sensor 13 is either an ultrasonic ranging sensor or an infrared ranging sensor. The ranging sensor 13 is positioned on the side of the lamp head 3 facing the user, with its detection direction corresponding to the light emission direction of the red light eye-protection light source 11, thus accurately reflecting the distance between the user's eyes and the red light emission surface. The camera 14 is positioned on the side of the lamp head 3 facing the user and is used to capture facial images. The control module 4 identifies the eye state and sitting posture based on the facial images. The eye state includes open eyes, closed eyes, and blinking states. The sitting posture includes the positional and directional shift of the face relative to the lamp head 3. The control module 4 obtains the blinking frequency based on this information. and sitting posture deviation .

[0049] The processing device in this embodiment further includes a communication module 7, a voice module 8, and a display module 9. The communication module 7 is electrically connected to the control module 4 and is used for data interaction with external terminal devices, which can be user mobile phones, tablets, or smart home terminals. The control module 4 can transmit user eye usage status data and red light irradiation records to the external terminal devices through the communication module 7, and can also receive preset control parameters or user settings sent by the external terminal devices. The voice module 8 is electrically connected to the control module 4 and is used to broadcast eye usage behavior guidance information. The display module 9 is electrically connected to the control module 4 and is used to display eye usage status information and guidance information. The displayed content may include continuous reading time, current eye fatigue level, remaining red light irradiation time, distance abnormality warnings, and rest reminders, etc.

[0050] In this embodiment, the control module 4 also performs eye-use behavior guidance steps. Specifically, the control module 4 generates eye-use behavior guidance information based on fatigue assessment results and red light irradiation implementation, and provides feedback to the user through the voice module 8 or the display module 9. When the continuous reading time reaches a preset rest threshold, the control module 4 issues a rest reminder through the voice module 8, or displays a rest prompt through the display module 9; when the sitting posture deviation... When the safety threshold is exceeded, control module 4 issues a posture correction prompt to remind the user to adjust their head position, reading distance, or facial orientation; after the red light eye protection irradiation ends, control module 4 issues a distance relaxation prompt to guide the user to relax their eyes. Thus, the device can not only adjust the eye position based on the fatigue index... Red light eye protection can also provide reminders about poor eye habits during reading, forming a process that combines eye status monitoring, fatigue assessment, red light intervention, and behavioral guidance.

[0051] It should be noted that the control method in the embodiments of this application can be automatically controlled by a controller. The control method of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect mechanical structures, so the control method and circuit connection will not be explained in detail here.

[0052] The technical solution in the above-described embodiments of this application collects multi-dimensional eye use status data through multiple sensors such as ambient light sensor 12, distance sensor 13, and camera 14, and calculates the fatigue index by combining it with an eye fatigue assessment model. This system achieves adaptive and graded adjustment of the red light eye protection irradiation strategy, avoiding the intervention mismatch problem caused by a single fixed mode. During red light irradiation, switching the reading lighting source 10 to the collaborative eye protection mode reduces the stimulation of the eyes by high color temperature and high brightness lighting. At the same time, multiple safety monitoring of distance, power, duration, frequency, and user's eye condition ensures the safety of the red light irradiation process. In addition, the voice module 8 and display module 9 provide users with feedback on rest reminders, posture correction, and distant relaxation guidance, forming a closed-loop processing from state perception to eye protection intervention to behavior guidance, improving the matching degree between red light eye protection irradiation and the user's actual eye use status and the safety of use.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
