Description

Technical Field

[0001] The present invention relates to the technical field of optical products, and in particular to an optical system for inhibiting myopia. Background Art

[0002] In recent years, with the popularization of electronic display devices and the change of eye - using habits, the problem of myopia has become increasingly serious, especially the incidence of axial myopia has increased significantly. Currently, the mainstream eye - protection technologies mainly focus on reducing the stimulation of harmful light on the eyes, such as using low - blue - light illumination, filtering blue light, or increasing red - light / infrared - light irradiation. These technologies delay the deepening of myopia by reducing the potential harm of environmental light, but their core mechanism still remains at the level of "passive protection" and lacks the ability to actively intervene in the development of myopia. Existing clinical data show that although such methods can relieve visual fatigue, they cannot effectively improve eyesight or inhibit the abnormal growth of the eye axis, so there are obvious limitations in the treatment effect.

[0003] In addition, existing eye - protection products mostly rely on users to independently adjust the use distance or time, lacking an intelligent real - time monitoring and feedback mechanism. For example, traditional devices cannot dynamically sense the change of the user's position, which may lead to unstable light intensity or improper use posture, thus affecting the treatment effect and even causing potential safety hazards. Although some studies have pointed out that specific wavelength light (such as ultraviolet light) may maintain the choroid thickness and inhibit the growth of the eye axis by stimulating photosensitive proteins (such as OPN5) in the retina and regulating the expression of related genes (such as EGR1), there is no mature product that can transform this scientific discovery into a safe and controllable clinical application plan. Therefore, we propose an optical system for inhibiting myopia. Summary of the Invention

[0006] A UV LED lamp board for emitting ultraviolet light with a wavelength of 350 - 405 nm;

[0007] A sensor module for detecting the position and distance of the user and generating corresponding feedback signals;

[0008] A control module, connected to the UV LED lamp board and the sensor module, for adjusting the light - emitting intensity of the UV LED lamp board according to the feedback signal so that the irradiance intensity of the ultraviolet light irradiated on the user's eyes is maintained between 100 μW / cm 2 and 300 μW / cm 2 ;

[0009] An indicator light module, connected to the control module, for guiding the user to adjust to the target position through color or brightness changes;

[0010] A guiding software, displayed on an external display device, for guiding the user's operation through a visual interface;

[0022] Optionally, the system is connected to the display device through a USB interface or a wireless module, and is used as an independent device or an accessory of the display device.

[0023] Optionally, the indicator light module is an RGB LED or a monochromatic LED, and indicates at least one of the following states through color or brightness changes: user position offset, abnormal ultraviolet light irradiation intensity, system operation status.

[0024] Optionally, when the control module detects that the user leaves the effective area, it performs at least one of the following operations: turning off the UV LED light board, reducing the light emission intensity, triggering the indicator light module to prompt to adjust the position.

[0025] Optionally, the ultraviolet light irradiation intensity is dynamically adjusted through a closed-loop control algorithm based on the real-time feedback data of the sensor module.

[0026] Optionally, the system is applicable to display devices such as televisions, monitors, laptops, tablets or mobile phones, and is integrated into the frame or bracket of the device.

[0027] Compared with the prior art, the present invention has the following beneficial technical effects:

[0028] By emitting UV light with a wavelength of 350 - 405 nm through the UV LED light board, it can effectively stimulate the eyeballs, relieve eye fatigue, improve eye blood circulation, and to a certain extent inhibit the development of myopia. The closed-loop control system accurately maintains an irradiation intensity of 100 μW / cm 2 to 300 μW / cm 2 to ensure the safety and effectiveness of the treatment.

[0029] The sensor module real-time senses the user's position and distance.

During the treatment process, it can also dynamically adjust the light emission intensity of the UV LED according to the small-range change of the user's position, ensuring the stability of the received UV light intensity and improving the treatment accuracy.

[0030] When the sensor detects that the user is away from the working area, the control module can adjust the light emission intensity or turn off the irradiation function to avoid energy waste and unnecessary irradiation, reducing potential risks. At the same time, the quartz glass panel or the ultraviolet-transparent material protective cover of the UV LED light board prevents the user from accidentally touching it, ensuring the use safety.

[0031] The indicator light module intuitively shows the working state of the product, the state of the UV LED, and whether the user's position is correct through lights of different colors and quantities, facilitating the user to quickly understand the product situation and operate according to the instructions, reducing operation troubles.

[0032] The guiding software provides comprehensive operation guidelines, including position adjustment, treatment process and time control, to ensure the eye protection effect. The design of playing soothing music and videos can relieve the user's tension and fatigue, improving the treatment comfort and compliance. Especially for users who use it for the first time or are not familiar with the operation, it can bring a better experience.

[0033] The present invention emits UV light of a specific wavelength through a UV LED light board, and cooperates with closed-loop control to ensure safe and effective treatment; the sensor module accurately senses the position, and the control module adjusts the light board accordingly and prompts the user, improving operation convenience and treatment accuracy; the indicator light intuitively displays the product status to assist operation; the guiding software guides comprehensively and improves the user's mood, enhancing comfort and compliance. Overall, it provides users with a safe, accurate, convenient and comfortable eye protection experience, helping to inhibit the development of myopia. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0037] Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] EMBODIMENT

[0040] As Figure 1 shown, an optical system for inhibiting myopia includes five parts: a UV LED light board, a sensor module, a control module, an indicator light module, and a guiding software. Each part will be described below.

[0041] In this embodiment, the UV LED lamp board refers to a PCB on which a number of UV LED lamp particles are mounted in a patch form, with a wavelength in the range of 350 - 405 nm. After being powered and driven by the control module, the lamp board can emit UV light of the corresponding wavelength. On the surface of the UV LED lamp board, there is an assembly including but not limited to a quartz glass panel or a UV-transparent material protective cover, which is used to protect the UV LED lamp board from being touched and at the same time ensure that the UV light emitted by it can pass through the protective cover without being blocked. Through the closed-loop control of the sensor component and the control component, the irradiation intensity of the UV light irradiating on the user's eyes is adjusted to be maintained between 100 μW / cm 2 and 300 μW / cm 2 . The emission of UV light with a specific wavelength stimulates the user's eyeballs for treatment, and the protective cover ensures the use safety. The closed-loop control ensures that the irradiation intensity is appropriate, providing stable and effective light source conditions for treatment.

[0042] Among them, one or more sensors are installed on the sensor module, including but not limited to TOF sensors, distance sensors or camera sensors. When the user uses this product, the sensor module can sense the user's position and distance, and whether the user is in the set working area. When the user is away from the working area, the sensor connects to the control module to select and adjust the light emission intensity, or turn off the irradiation function, or prompt through an indicator light that this product is in an inactive state. Accurately sensing the user's position and distance ensures that the user receives treatment at the appropriate position, and through feedback control, the dynamic adjustment of the UV light irradiation intensity is realized, improving the accuracy and effectiveness of treatment, and avoiding affecting the treatment effect or causing potential risks due to improper position.

[0043] As Figure 2 shown, when there is a deviation in the user's position, the sensor module feeds back to the control module according to the user's position. The control module indicates to the user to adjust to the correct position through the color or brightness of the indicator light. At the same time, the control module also feeds back the sensor data to the guiding software to guide the user to adjust to the correct position in the form of a screen display. When the user's position and distance are reasonable, the sensor module feeds back to the control module to start the UV LED to emit light and stimulate the user's eyeballs for treatment. During the treatment process, the sensor module will continuously detect the user's position. When the user's position moves back and forth, within a reasonable range, the sensor module will feedback and reduce or increase the light emission intensity of the UV LED through the control module to ensure that the intensity of the UV light received by the user's eyes does not change. When the user has other position offsets, or the eyes cannot receive the UV light, the sensor module senses this situation, controls the indicator light through the control module, and feeds back to the guiding software to indicate to the user to re-adjust the position.

[0044] In addition, the control module is used to control the operation of the entire product, which includes but is not limited to power drive, main control circuit, and communication circuit. This eye protection product is connected to products such as TVs, monitors, or laptop computers through USB or a dedicated connector, takes power through a wire harness or wireless module, and can choose whether to communicate with the host product. The power module is used to drive the UV LED lights, light up the indicator lights, and drive the sensors and main control circuit to work; the main control circuit controls the operation of the entire product according to the feedback information of the sensors and the process of the guiding software; the communication circuit enables the product to communicate with the display host through USB or other dedicated connection methods, and combines the operation of the product with the guiding software. It realizes comprehensive control of the operation of the entire product, coordinates the work of each part, ensures the stable operation of the product, provides stable power support for each module, and optimizes the product usage experience and treatment effect through cooperation with the display host and the guiding software.

[0045] It is worth noting that multiple RGB LEDs or monochromatic LEDs are installed on the PCB surface in the form of surface mount or plug-in for the indicator lights. According to the control of the control module, they can emit corresponding colors or numbers of lights to indicate the current usage status of the user, whether the position is correct, etc. It is used to assist the user to look at the UV emission area and guide the user to operate according to the instructions. It conveys important information to the user in an intuitive visual way, helps the user quickly understand the product status and their own position, facilitates the user to operate correctly according to the instructions, and improves the convenience and user experience of product use.

[0046] Furthermore, the guiding software is installed on the display host product and displayed on the monitor of the host product, and is used to guide the customer to perform eye protection operations. The software will guide the customer to be in a suitable position, perform corresponding operations, and execute corresponding time to ensure the eye protection effect. Finally, it improves the mood by playing soothing music and videos. The guiding software is not an essential part of the present invention. On some products, the guiding software may not be required, and only the indicator lights or voice on the product are used to guide the customer to complete the treatment and eye protection operations. It provides detailed and visual operation guidelines for users, helps users use the product in a standardized manner, ensures the best eye protection effect, and at the same time, the soothing music and videos help improve the user's mood and enhance the comfort and compliance of the user during the treatment process.

[0047] Working principle: When the user is ready to use this myopia-inhibiting optical system, each module of the system collaborates to start working. The user connects the product to a display host such as a TV, monitor, or laptop via USB or a dedicated connector. The power driver in the control module obtains power from the connected device through a wire harness or a wireless module to supply power to the entire system, including the UV LED light board, the sensor module, the indicator module, and the main control circuit. The main control circuit is initialized and establishes a communication connection with the guiding software, which is loaded and run on the display host monitor to prepare to provide operation guidance for the user.

[0048] Sensors such as the TOF sensor, distance sensor, or camera sensor in the sensor module start to continuously sense the user's location and the distance from the product. If the user is away from the set working area of the product, the sensor module transmits the signal to the control module. According to the preset program, the control module either reduces the light emission intensity of the UV LED light board to avoid energy waste, or directly turns off the irradiation function of the UV LED light board to prevent ineffective irradiation. At the same time, it uses the indicator module to prompt the user that the product is not working through specific color or brightness changes.

[0049] When the user gradually approaches and enters the appropriate working area, after the sensor module detects a reasonable position and distance, it feeds back to the control module. On the one hand, the control module starts the UV LED light board, driving the UV LED light particles surface-mounted on the PCB board to emit UV light with a wavelength of 350 - 405 nm to perform therapeutic stimulation on the user's eyes, helping to relieve eye fatigue, improve blood circulation, and inhibit the development of myopia. On the other hand, it transmits the sensor data to the guiding software, and the guiding software prompts the user on the display host screen that they are in the appropriate position and can start the treatment. At the same time, the indicator module also shows that the product has entered the working state through a specific light state.

[0050] During the treatment process, the sensor module continuously monitors the user's position. If the user's position moves slightly forward and backward within a reasonable range, the sensor module feeds back the position change information to the control module, and the control module immediately adjusts the power supply intensity of the UV LED light board to ensure that the UV light irradiation intensity received by the user's eyes is stably maintained between 100 μW / cm 2 and 300 μW / cm 2 to ensure stable treatment effects. Once the user's position shows a large deviation, or the eyes cannot receive UV light normally, the sensor module quickly senses and transmits the signal to the control module. On the one hand, the control module intuitively reminds the user of the position deviation by changing the light state of the indicator module. On the other hand, it feeds back the abnormal position data to the guiding software, and the guiding software details and guides the user to readjust the position on the display host screen in the form of a picture to ensure the smooth progress of the treatment process and avoid treatment interruption or poor effects caused by improper position.

[0051] During this period, the indicator light module works according to the instructions of the control module at all times. In addition to displaying the working status of the product and position prompts, during the user operation, it also uses the change of lights in different colors or quantities to assist the user in quickly locating the UV emission area, guiding the user to operate in the correct way, and improving the usability. The guiding software not only guides the user to complete key steps such as position adjustment and treatment operation, strictly controls the treatment time to ensure the eye protection effect, but also helps the user relax physically and mentally, relieve the tension and fatigue during the treatment process, improve the user's comfort and compliance, and further optimize the treatment experience.

[0052] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
