Description

Technical Field

[0001] The present invention belongs to the fields of bio-photonics, medical devices, advanced treatment technology, and myopia prevention and control technology. More specifically, it relates to a new type of lighting source classroom for controlling the occurrence and development of myopia and a method of using the same. Background Art

[0002] Myopia, also known as short-sightedness, usually begins in childhood. Severe forms of myopia (pathological myopia) are associated with the risk of other related ophthalmic problems, including retinal detachment, fundus retinopathy, cataracts, glaucoma, and even blindness. Although there are currently targeted clinical treatments, such as low-concentration atropine eye drops, wearing orthokeratology lenses, and surgical treatment, these methods are all individualized. For a large patient population of millions, tens of millions, or even hundreds of millions, it is very difficult to reduce the burden of myopia on humans by relying solely on treatment. There is an urgent need to develop broad-spectrum, effective, and group-based myopia prevention and control measures to prevent the onset of myopia and slow down its progression. Among them, developing measures that can effectively prevent the occurrence of myopia in children and adolescents and slow its development is a top priority.

[0003] It is generally believed that the formation of myopia is accompanied by the thinning of the choroid and the elongation of the eye axis. The close connection between changes in choroidal thickness and changes in eye growth in a variety of animals suggests that the choroid plays an important role in regulating eye growth and the occurrence of refractive errors. Although the exact molecular pathways and mechanisms linking the choroid to changes in eye growth have not yet been clarified, the anatomical location of the choroid between the retina and the sclera suggests that the choroid has a potential role in the transmission of retinal signal molecules and growth factors to the sclera, or plays a role in the production of growth factors that directly affect scleral growth. Read SA et al. (Clin. Exp. Optom., 2019, 102 (3), 270-285.) used optical coherence tomography to explore the changes in the choroid in human myopia. Their research showed that the choroid is thinner in myopic eyes than in emmetropia and hyperopia, and the deeper the myopia, the thinner the choroid. In recent years, a large number of scholars have conducted research from the perspective of light exposure, believing that exposure to outdoor light during childhood can reduce the risk of myopia or delay the progression of myopia. Some studies have sorted out the relationship and mechanism of action between outdoor light and myopia that have been discovered so far, and found that outdoor light can cause photochemical reactions in the retina, stimulate the synthesis and release of dopamine, increase choroidal blood perfusion, promote choroidal thickening, regulate scleral remodeling and eye growth, and changes in light intensity and wavelength are correlated with the progression of myopia. As an intervention target, it has certain potential in controlling the progression of myopia. JIANG Y et al. (Ophthalmology, 2022, 129(5), 509-519.) found that low-intensity red light therapy can effectively control the progression of myopia in school-age children, and some children have axial regression and decreased myopia. Therefore, directly using light as an intervention method is expected to become one of the effective ways to prevent and control myopia.

[0004] In recent years, primary and secondary schools across the country have replaced all classroom lighting fixtures that do not meet the standards for illumination and flicker in accordance with the deployment of the Ministry of Education. This has made up for the shortcomings of classroom lighting fixtures in the past to a certain extent. However, classroom lighting generally uses white light sources, whether in the form of fluorescent lamps or full-spectrum white light LED light sources, which do not have the function of actively preventing and controlling myopia. Summary of the invention

[0005] The purpose of the present invention is to provide a new type of lighting source for classrooms that controls the occurrence and development of myopia in response to the deficiencies in the prior art, thereby solving the problem that existing classroom lighting generally adopts white light sources, which, regardless of whether they are in the form of fluorescent lamps or full-spectrum white light LED light sources, do not have the function of actively preventing and controlling myopia.

[0006] In order to achieve the above object, the present invention provides a new type of lighting source classroom for controlling the occurrence and development of myopia, comprising:

[0007] A color light illumination system, wherein the wavelength of emitted light of the color light illumination system is a part or all of 550-1100 nm;

[0008] The emitted light of the color light illumination system can be directly emitted or reflected into the human eye.

[0009] Optionally, a white light illumination system is further included, and the white light illumination system and the color light illumination system are used simultaneously or alternately.

[0010] Optionally, the colored light illumination system includes an LED light emitting device, a wavelength-filtered xenon lamp light source, or a wavelength-filtered deuterium lamp light source.

[0011] Optionally, the colored light illumination system is arranged on the table body and can directly illuminate the eyes.

[0012] Optionally, the colored light illumination system is arranged on the roof via a telescopic rod and can be close to or far away from the ground.

[0013] Optionally, the color light illumination system is fixedly installed on the wall or floor of the classroom.

[0014] Optionally, the color light illumination system and the white light illumination system are integrated into one body, and the color light illumination system and the white light illumination system are respectively provided with a brightness control unit.

[0015] The present invention also provides a method for using a new type of lighting source for controlling the occurrence and development of myopia in a classroom, and the method comprises:

[0016] Classrooms with new lighting sources are used alternately with ordinary classrooms.

[0017] Optionally include:

[0018] The new lighting source classroom is equipped with a white light lighting system, and the white light lighting system and the color light lighting system are used simultaneously or alternately.

[0019] Optionally, when the white light illumination system and the colored light illumination system are used simultaneously, the brightness of the white light illumination system is lowered.

[0020] The present invention provides a new type of lighting source classroom for controlling the occurrence and development of myopia, and its beneficial effects are:

[0021] 1. The new lighting source classroom for controlling the occurrence and development of myopia emits 550-1100nm far-red light through the color light lighting system to stimulate the eyes, thereby achieving non-contact prevention and treatment of myopia. It can be carried out by multiple people at the same time, improving the prevention and treatment efficiency and is suitable for use in student classrooms.

[0022] 2. Compared with conventional corneal contact lenses, frame glasses and drug intervention technologies for controlling myopia progression, the technology used utilizes far-infrared light to promote choroidal thickening and improve retinal choroidal hypoxia, inhibits scleral remodeling, and delays axial elongation. The technology provided is more convenient and safer, and can be used to conduct large-scale myopia prevention and treatment for students while they are in school. A large number of people are involved, and the efficiency is higher than intervening on a single individual. It is expected to significantly reduce the incidence of myopia in society and significantly delay the progression of myopia in society.

[0023] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0033] like Figure 1-5 As shown, a new type of lighting source classroom for controlling the occurrence and development of myopia includes:

[0034] A color light illumination system 1, wherein the wavelength of emitted light of the color light illumination system 1 is a part or all of 550-1100 nm;

[0035] The emitted light of the color light illumination system 1 can be directly emitted or reflected into the human eye.

[0036] Specifically, the color light illumination system 1 emits 550-1100nm far-red light to stimulate the eyes, thereby achieving contactless prevention and treatment of myopia, and can be performed by multiple people at the same time, thereby improving the prevention and treatment efficiency and being suitable for use in student classrooms.

[0037] Furthermore, the color light illumination system 1 is intermittently activated, which can be activated during class breaks, before class, after class or during class, and enters the fundus through direct or reflected light. The illumination time between two consecutive illuminations is not less than 45 minutes; each continuous illumination does not exceed 30 minutes, preferably 5-15 minutes; each illumination exposure to the eye is 0.01-3J / cm 2 The cumulative daily eye exposure radiation does not exceed 10J / cm 2 .

[0038] Furthermore, the color light illumination system 1 is an independent table lamp structure or is arranged as a roof lamp and a wall lamp, and the classroom is equipped with blackout curtains.

[0039] In this embodiment, a white light illumination system 2 is also included. The white light illumination system 2 and the color light illumination system 1 are used simultaneously or alternately.

[0040] Specifically, the white light illumination system 2 is adapted to the daily use of the classroom, and the white light illumination system 2 is turned off or the brightness is reduced when the colored light illumination system 1 is started. The white light illumination system 2 includes a common incandescent lamp or an LED lamp.

[0041] In this embodiment, the color light illumination system 1 includes an LED light emitting device, a wavelength-filtered xenon lamp light source, or a wavelength-filtered deuterium lamp light source.

[0042] Specifically, the LED light-emitting device includes:

[0043] LED blue light chip;

[0044] Red light-near infrared light phosphor is packaged together with LED blue light chip.

[0045] In this embodiment, the color light illumination system 1 is arranged on the table and can directly illuminate the eyes.

[0046] Specifically, the color light illumination system 1 is arranged on the table body through a bellows, a folding mechanism or a lifting mechanism, and is stored on the side of the table body or in a table box of the table body when not in use.

[0047] In this embodiment, the color light illumination system 1 is arranged on the roof through a telescopic rod and can be close to or far away from the ground.

[0048] Specifically, the colorful lighting system 1 is arranged by a telescopic rod for easy use and adjustment, and is suitable for students of different heights or postures, such as a partially foldable reclining lunch break chair.

[0049] In this embodiment, the color light illumination system 1 is fixedly installed on the wall or floor of the classroom.

[0050] Specifically, the colored light illumination system 1 is fixed on a wall, floor or roof, and is dispersedly arranged through a plurality of separate lighting units, and enters the human eye in the form of diffuse reflection or direct light. Compared with direct light into the human eye, which requires students to actively look at it or maintain a certain posture, it is more relaxing and comfortable.

[0051] Preferably, the colored light illumination system 1 is laterally fixed on the walls at the back row and on the left and right sides of the classroom according to the appropriate height of students of different grades, so that the light-emitting surface can be parallel to the eyes of students of different heights. During the break, the light source is automatically lit by the automatic control system, and students can complete the light therapy while playing in the back row and on the left and right aisles of the classroom during the break.

[0052] In this embodiment, the color light illumination system 1 and the white light illumination system 2 are integrated into one body, and the color light illumination system 1 and the white light illumination system 2 are respectively provided with a brightness control unit.

[0053] Specifically, when the colored light illumination system 1 is started, the white light illumination system 2 is appropriately lowered or turned off to avoid interference between the two.

[0054] The present invention also provides a method for using a new type of lighting source for controlling the occurrence and development of myopia in a classroom, and the method comprises:

[0055] Classrooms with new lighting sources are used alternately with ordinary classrooms.

[0056] Specifically, students enter the new lighting source classroom on a regular basis for myopia prevention and treatment. Because it is a separate new lighting source classroom, the cost is lower and the resource utilization rate is higher than if each classroom is equipped with a color light lighting system 1.

[0057] In this embodiment, it includes:

[0058] A white light lighting system 2 is arranged in the classroom of the novel lighting source, and the white light lighting system 2 and the color light lighting system 1 are used simultaneously or alternately.

[0059] Specifically, a color light lighting system 1 is added to ordinary classrooms to prevent and treat myopia according to the teaching progress and class schedule of each class.

[0060] In this embodiment, when the white light illumination system 2 and the colored light illumination system 1 are used simultaneously, the brightness of the white light illumination system 2 is lowered.

[0061] Embodiment 1

[0062] like Figure 1-2 As shown, the color light lighting system and the white light lighting system are integrated and set on the roof of the classroom;

[0063] By integrating far-red LED lamp beads with an emission wavelength of 550-1100nm into the existing LED classroom lighting source, a new lighting source is made. A two-way lighting control system is used, one to control white light lighting and one to control far-red LED lamp beads. The operation time of the LED lamp beads is set according to the school's schedule. The far-red LED lamp beads are lit 10 minutes before the first class in the morning and afternoon every day, and the far-red light is automatically turned off during class. The far-red LED lamp beads are lit during the break period. The far-red LED lamp beads are lit for 10 minutes after school every morning and afternoon. During the break, the brightness of the white light fixture is reduced from 300-500 lux to 100-300 lux. The two-way control system is integrated into a controller using a single-chip microcomputer. The controller panel provides two control methods, one is manual, on-demand lighting; the other is automatic cycle control. After the first person to school touches the lighting switch every morning, the system automatically synchronizes with the Beijing time on the Internet, and then cycles the white light and far-red light beads according to the schedule time. The controller provides a manual priority control mode. When the manual on-demand control mode is triggered, the automatic cycle control mode is terminated. Figure 1As shown. Starting from September 2023, a class in the second grade of a primary school and two classes in the third grade were randomly selected as the experimental group (a total of 78 people), and one class each from the second and third grades were selected as the control group (a total of 52 people). The control group uses conventional classroom lights. The classrooms in the experimental group use a new lighting source that combines white light with far-infrared light, using an intelligent control mode, which lasts for 4 months (completed within one semester). The equivalent spherical lens, axial length, and visual acuity changes of the students in the experimental group were tested before and after 4 months using the new lighting source, and the changes in visual acuity, axial length, and refractive power of the control group were tested at the same time point. Visual acuity was checked with an automatic ophthalmometer, and the average value was taken after three measurements. The spherical, cylindrical and astigmatic axes were recorded, and the refractive power, i.e. the equivalent spherical power (equivalent spherical power = spherical power + 1 / 2 cylindrical power), was also recorded. The IOL Master biometer was used to measure the axial length and corneal curvature. The axial length (AL) was defined as the distance between the tear film surface and the retinal pigment epithelium. The average value was taken after five measurements. Visual acuity, axial length and refractive power were only measured from the right eye. After excluding lost follow-up and extreme data, 48 people were obtained in the control group and 62 people in the experimental group. The sample statistics are shown in Tables 1 and 2. Judging from the average values, visual acuity improved and axial length growth was delayed after the intervention. The average values ​​and error values ​​of the differences before and after treatment of the collected data were statistically compared. Figure 2 SPSS software was used to analyze the visual acuity, axial length and diopter of two independent samples. The statistical results showed that the P values ​​of the differences in visual acuity, axial length and diopter before and after the intervention were all less than 0.05, which was statistically significant. There were differences in the collected data before and after the intervention, as shown in Table 3, indicating that the new lighting source classroom constructed by the present invention can effectively control the occurrence and development of myopia.

[0070] Embodiment 2

[0071] like Figure 3 As shown, the color light illumination system is arranged on the student's desk through a corrugated tube;

[0072] A special light-emitting device is made by using far-red LED lamp beads and placed on the desk. Such a medical classroom is built in each school (the classroom can be directly designed as a darkroom). Students go to the phototherapy classroom in batches before, during or after class for phototherapy. The light-emitting surface faces the students' eyes. During phototherapy, students look at the light-emitting surface and keep their eyes parallel to the light-emitting surface. Each time lasts 5-10 minutes, 2-4 times a day.

[0073] Embodiment 3

[0074] like Figure 4 As shown, the far-red LED lamp beads are set on the classroom roof through a lifting mechanism, which can be an electric lift or manually extended. When in use, the lamp automatically falls in front of the students to ensure that the students' eyes can face the red light surface. When not in use, the lamp retracts to the ceiling.

[0075] The far-red LED lamp beads and the electric lift are connected to an automatic electric control device, which can be started 10 minutes before the first class in the morning and afternoon and 10 minutes after school in the morning and afternoon. When started, the far-red LED lamp beads descend and light up the far-red LED lamp beads, and automatically rise and retract and turn off the far-red light during class;

[0076] When activated, the brightness of the white light lighting system can be reduced from 300-500 lux to 100-300 lux;

[0077] In the case of using far-infrared LED lamp beads to prevent and treat myopia during evening self-study, the use of far-infrared LED lamp beads is similar to that during the day.

[0078] Embodiment 4

[0079] like Figure 5 As shown, far-red LED lamp beads are placed on the walls around the classroom;

[0080] A stretchable lamp is made by using far-red LED lamp beads and placed on the walls around the classroom. The installation angle can be parallel to the wall, or it can be installed on the classroom wall at a 45-degree or 60-degree angle. The installation height of the lamp can be adjusted according to the different classrooms used in primary and junior high schools from grade 1 to grade 6 or grade 1 to grade 3, and the installation height around the walls in each classroom can also be different, so as to facilitate the use of students of different heights. The far-red LED lamp beads are lit 10 minutes before the first class in the morning and afternoon every day, and the far-red light is automatically turned off during class. The far-red LED lamp beads are turned on during the break period. The far-red LED lamp beads are lit for 10 minutes after school every morning and afternoon. The brightness of the white light lamp is reduced from 300-500 lux to 100-300 lux during the break.

[0081] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
