Description

Technical Field

[0001] This invention relates to the field of desk lamp lighting, specifically to a full-color bionic eye-protecting desk lamp and its lighting method. Background Technology

[0002] As an independent light source, the desk lamp has been widely used in people's lives. A desk lamp generally refers to an electric lamp with a base placed on a table, mainly used for lighting purposes such as reading, studying, and working.

[0003] The human eye was formed and evolved under natural light, and its adaptability to natural light is irreplaceable. When looking at pure blue light, the eye naturally widens to focus the image onto the retina; when looking at pure red light, the eye naturally squints to focus the image onto the retina. Ordinary artificial lighting has a lack of red light and an excessive amount of blue light. Prolonged use of these lights can damage the macula of the retina and easily cause eye fatigue, leading to myopia. Strengthening the red light spectrum and reducing the blue light spectrum in lighting is crucial for reducing eye fatigue and preventing myopia.

[0004] Furthermore, when people are reading or writing, they often stare intently at the object they are looking at. After prolonged viewing, the eyes become fixed in one spot for a long time, which can easily lead to eye fatigue. In particular, when the red light spectrum is missing from the light spectrum, prolonged viewing can cause the axial length of the eye to increase, resulting in myopia.

[0005] Therefore, it is of great significance to develop a desk lamp and its lighting method that is simple in structure, easy to store, and can effectively achieve an adjustable eye axis method that conforms to visual habits to protect the eyes, reduce eye fatigue, and reduce or prevent myopia. Summary of the Invention

[0006] The purpose of this invention is to address the problem of eye fatigue after prolonged use when reading or writing, especially when the desk lamp source lacks red light or has a weak red light spectrum. This fatigue can lead to elongation of the eye axis and myopia. This invention provides a full-color bionic eye-protecting desk lamp and its lighting method. The lamp has a simple structure and is easy to store. Furthermore, the lighting method provides independent dimming bionic visual control, transforming static light into dynamic light. The spectrum remains unchanged when brightness changes and does not cause visual adaptation. This allows the eye to blink, and the eyeball to autonomously refocus and reset, thereby achieving active adjustment of the eye axis, conforming to visual habits. This protects the eyes, reduces eye fatigue, and alleviates or prevents myopia.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A full-color bionic eye-protection desk lamp includes a support cover, a main board, and a folding panel;

[0009] The main board is fixedly connected to the support cover, and the folding panel is hinged to the main board; the folding panel can be rotated around the main board to a certain angle and then locked, and can also be released and rotated around the main board to fit against the main board;

[0010] An LED light source component is provided on the surface of the folding panel near the main board, and the light source of the LED light source component is a full-color bionic light source;

[0011] It also includes an LED driver device, which is electrically connected to the LED light source component. The LED driver device can drive the current of the LED light source component to change, so as to achieve changes in lighting brightness and / or color temperature value.

[0012] This invention discloses a full-color bionic eye-protection desk lamp, comprising a support cover, a main board, and a folding panel. The main board is fixedly connected to the support cover, and the folding panel is hinged to the main board. The folding panel can rotate around the main board to a certain angle and then lock in place, and can also be released and rotated around the main board to fit snugly against it. An LED light source component is disposed on the surface of the folding panel near the main board, and the light source of the LED light source component is a full-color bionic light source. It also includes an LED driving device, which is electrically connected to the LED light source component and can drive changes in the current of the LED light source component to achieve changes in lighting brightness and / or color temperature. Firstly, the full-color bionic eye-protection desk lamp provided by this application allows the folding panel to be fixed around the main board to fit snugly against it when not in use, and the folding panel can be fixed in place when in use after rotating around the main board to a certain angle. The structure is simple, convenient to use, and easy to store. Meanwhile, the full-color bionic eye-protection desk lamp provided in this application forms a high-saturation red light and a high-saturation cyan light existence mode in the spectrum of the lighting source. Based on the imaging principle of color on the retina, the full-color bionic light source helps to adjust the focal length and axial length of vision during visual imaging, realize the visual imaging of object color reproduction, ensure high visual adaptability and comfort, and effectively relieve eye fatigue under lighting.

[0013] Furthermore, the approximation of the radiation power distribution curve of the full-color bionic light source to natural light of the same color temperature is 95% ± 5%. This means that the ratio of the smaller absolute light power to the larger absolute light power in any same wavelength band of the spectrum of the full-color bionic light source and the spectrum of natural light of the same color temperature is 95% ± 5%.

[0014] Preferably, in the spectrum of the panchromatic bionic light source, the approximation degree of the radiant power distribution curve of the light source to natural light of the same color temperature is Ai / Bi; where Ai refers to the radiant amount of the panchromatic bionic light source at 1 nm, and Bi is the radiant amount of the natural light spectrum of the same color temperature at 1 nm; Ai / Bi = 90%~100%, where 380nm≤i≤700nm. More preferably, when 380nm≤i≤480nm, Ai / Bi is 90%~95%; when 480nm≤i≤600nm, Ai / Bi is 95%~100%; and when 600nm≤i≤700nm, Ai / Bi is 90%~100%.

[0015] Preferably, when the color temperature of the full-color bionic light source is 2700K-3000K, the absolute light power value of the violet light in the spectrum of the full-color bionic light source is less than 0.35 in the range of 380-435nm; the absolute light power value of the blue light in the range of 435-475nm is greater than 0.40; the absolute light power value of the cyan light in the range of 475-492nm is greater than 0.45; the absolute light power value of the green light in the range of 492-577nm is greater than 0.50; the absolute light power value of the yellow light in the range of 577-597nm is greater than 0.75; the absolute light power value of the orange light in the range of 597-622nm is greater than 0.80; and the absolute light power value of the red light in the range of 622-700nm is greater than 0.80.

[0016] Preferably, when the color temperature of the full-color bionic light source is 4000K-4200K, the absolute light power value of the violet light in the spectrum of the full-color bionic light source is less than 0.40 in the 380-435nm range; the absolute light power value of the blue light in the 435-475nm range is less than 0.65 in the 435-475nm range; the absolute light power value of the cyan light in the 475-492nm range is greater than 0.60 in the 475-492nm range; the absolute light power value of the green light in the 492-577nm range is greater than 0.65 in the 492-577nm range; the absolute light power value of the yellow light in the 577-597nm range is greater than 0.80 in the 577-597nm range; the absolute light power value of the orange light in the 597-622nm range is greater than 0.8 in the 622-700nm range; and the absolute light power value of the red light in the 622-700nm range is greater than 0.80 in the 622-700nm range.

[0017] Preferably, when the color temperature of the full-color bionic light source is 5500K-6000K, the absolute light power value of the violet light in the spectrum of the full-color bionic light source is less than 0.45 in the range of 380-435nm; the absolute light power value of the blue light in the range of 435-475nm is less than 0.80; the absolute light power value of the cyan light in the range of 475-492nm is greater than 0.70; the absolute light power value of the green light in the range of 492-577nm is greater than 0.80; the absolute light power value of the yellow light in the range of 577-597nm is greater than 0.80; the absolute light power value of the orange light in the range of 597-622nm is greater than 0.80; and the absolute light power value of the red light in the range of 622-700nm is greater than 0.70.

[0018] Spectral power refers to the fact that the spectrum emitted by a light source is often not a single wavelength, but rather a mixture of radiation of many different wavelengths. The distribution of the spectral radiation of a light source according to wavelength order and the intensity of each wavelength is called the spectral power distribution of the light source. Parameters used to characterize the magnitude of spectral power are divided into absolute spectral power and relative spectral power. The absolute spectral power distribution curve is a curve plotted using the absolute values ​​of light energy at various wavelengths of the spectral radiation. The relative spectral power distribution curve is a curve that compares the energy of various wavelengths of the light source's radiation spectrum, normalizes it, and ensures that the radiant power varies only within a specified range. The relative spectral power with the highest radiant power is 1, and the relative spectral power of other wavelengths is less than 1.

[0019] Furthermore, the motherboard is provided with a groove for placing the LED light source component.

[0020] Furthermore, a power switch is provided on the motherboard; a charging port is provided on the support cover.

[0021] Furthermore, the LED light source component includes a high color temperature light source group and a low color temperature light source group;

[0022] The LED driving device can drive the low color temperature light source group and the high color temperature light source group respectively, adjust the current I1 of the low color temperature light source group and the current I2 of the high color temperature light source group to adjust the change of lighting brightness; adjust the current ratio of the low color temperature light source group and the high color temperature light source group to adjust the change of lighting color temperature value.

[0023] Furthermore, the high color temperature light source group is composed of at least two rows of high color temperature light source arrays connected in series, parallel, or series-parallel, and the low color temperature light source group is composed of at least two rows of low color temperature light source arrays connected in series, parallel, or series-parallel. All the high color temperature light source arrays and all the low color temperature light source arrays are arranged at intervals, and the light source array adjacent to the high color temperature light source array is the low color temperature light source array, and the light source array adjacent to the low color temperature light source array is the high color temperature light source array.

[0024] The high color temperature light source array is composed of several high color temperature LEDs connected in series, parallel, or series-parallel; the low color temperature light source array is composed of several low color temperature LEDs connected in series, parallel, or series-parallel.

[0025] Studies have found that eye-protecting lighting effects can be achieved by staggering high color temperature light source arrays and low color temperature light source arrays. However, the eye-protecting lighting effect is significantly reduced when all high color temperature light source arrays are arranged side by side and all low color temperature light source arrays are arranged side by side, or when two or more light source strips of the same color temperature are arranged at intervals.

[0026] This invention divides the LED light source component into a high color temperature light source group and a low color temperature light source group. The high color temperature light source group consists of high color temperature light source arrays, and the low color temperature light source group consists of low color temperature light source arrays. The arrangement of the high color temperature light source arrays and the low color temperature light source arrays is specifically adjusted. By adjusting the current ratio passing through the low color temperature light source group and the high color temperature light source group, the change in illumination color temperature value can be adjusted. By simultaneously adjusting the magnitude of the current I1 of the low color temperature light source group and the magnitude of the current I2 of the high color temperature light source group, the change in illumination brightness can be adjusted. By adjusting the coordination of the changes in illumination color temperature value and brightness, the human eye can be involuntarily blinked, and the eyeball can automatically refocus and reset, thereby actively adjusting the axial length of the eye and preventing the axial length of the eye from increasing.

[0027] Furthermore, the color temperature of the low color temperature light source group and the color temperature of the high color temperature light source group are two different color temperature values ​​within the range of 2700K-5600K. Preferably, the color temperature of the low color temperature light source group and the color temperature of the high color temperature light source group are any two color temperature ranges within the ranges of 2700K-3000K, 4000K-4200K, 4700K-5200K, and 5500K-6000K.

[0028] Another object of the present invention is to provide an illumination method for the above-mentioned full-color bionic eye-protection desk lamp.

[0029] A lighting method for the aforementioned full-color bionic eye-protection desk lamp includes the following steps:

[0030] Step 1: The lighting source gradually changes from the highest color temperature value to the lowest color temperature value. During the color temperature change, the lighting maintains a constant 100% brightness value, and the color temperature change time is 10s to 14s. Then, while keeping the lowest color temperature value constant, the lighting brightness value decreases from 100% brightness value to 25% to 45% brightness value within 0.8s to 1.1s, and is maintained for 3s to 5s. After that, the brightness value increases back to 100% brightness value within 0.8s to 1.1s.

[0031] Step 2: The lighting source gradually changes from the lowest color temperature value to the highest color temperature value. During the gradual change, the lighting maintains a constant 100% brightness value, and the color temperature change time is 10s to 14s. Then, while maintaining the highest color temperature value, the lighting brightness decreases from 100% brightness value to 25% to 45% brightness value within 0.8s to 1.1s, and the lighting is maintained for 3s to 5s. After that, the brightness value increases back to 100% brightness value within 0.8s to 1.1s.

[0032] Step 3: Repeat steps 1 to 2 to perform cyclic lighting; wherein in step 1, the total lighting time is 15s to 20s, and in step 2, the total lighting time is 15s to 20s.

[0033] The lighting method of the full-color bionic eye-protection desk lamp provided by this invention includes the following steps: Step 1: The lighting source gradually changes from the highest color temperature value to the lowest color temperature value. During the color temperature change, the lighting maintains a constant 100% brightness value, and the color temperature change time is 10s to 14s; then, while maintaining the lowest color temperature value, the lighting brightness value decreases from 100% brightness value to 25% to 45% brightness value within 0.8s to 1.1s, and the lighting is maintained for 3s to 5s; afterwards, the brightness value rises to 100% brightness value within 0.8s to 1.1s; Step 2: The lighting source gradually changes from the lowest color temperature value to the highest color temperature value. During the gradual change, the illumination maintains a constant 100% brightness value, and the color temperature gradual change time is 10s to 14s; then, while maintaining the highest color temperature value, the illumination brightness decreases from 100% brightness value to 25% to 45% brightness value within 0.8s to 1.1s, and is maintained for 3s to 5s; afterwards, the brightness value rises to 100% brightness value within 0.8s to 1.1s; step 3, repeat steps 1 to 2 to perform cyclic illumination; wherein in step 1, the total illumination time is 15s to 20s, and in step 2, the total illumination time is 15s to 20s. Throughout the lighting process, by coordinating the changes in color temperature and brightness, the system completes the transition from high to low brightness and from low to high brightness within a specific timeframe during the gradual color temperature change. This transforms static light into dynamic light while avoiding visual adaptation. By specifically adjusting the brightness and color temperature of the lighting source during the lighting process, and under excellent lighting conditions, the system mimics the natural changes in brightness, effectively "resetting" the eye's active adjustment of the eye axis. This causes the eye to blink unconsciously, and the active adjustment of the eye axis conforms to visual habits, thereby achieving the effects of protecting the eyes, reducing eye fatigue, and alleviating or preventing myopia.

[0034] Furthermore, in step 1, the time for the lighting source to gradually change from the highest color temperature value to the lowest color temperature value is 10s to 13s. For example, 10s; 11s; 12s; 13s.

[0035] Furthermore, in step 2, the time for the lighting source to gradually change from the lowest color temperature value to the highest color temperature value is 10s to 13s. For example, 10s; 11s; 12s; 13s.

[0036] Furthermore, in step 1, the illumination brightness decreases from 100% to 25% to 45% within 0.8s to 1.0s, and is maintained for 3.5s to 5s. Research has found that the time it takes for the brightness to decrease from high to low, and the duration of illumination at low brightness, are key factors in enabling involuntary blinking and active adjustment of the eye axis. Under the synergistic effect of a reasonably selected range of low brightness, eye comfort can be effectively improved, eye fatigue relieved, and the eyes protected, thus reducing or preventing myopia. However, adjusting the brightness from high to low too quickly will cause an adaptive effect on the human eye. The eye cannot adjust its axis in time because the adaptation time of vision to changes or switching in light intensity, or the adaptive conditioned reflex of vision to external senses, will prevent the eye axis from changing, making it impossible to actively adjust the eye axis, thus hindering the relief of eye fatigue and the reduction or prevention of myopia. However, adjusting the brightness value too slowly from high to low will not achieve the desired transition from static to dynamic light, significantly reducing the effectiveness in relieving eye fatigue and failing to provide adequate eye protection. In step 1, the time for the brightness value to decrease from high to low can be 0.8s, 0.9s, or 1s. The illumination time for the low brightness value in step 1 can be 3.5s, 4s, 4.5s, or 5s.

[0037] Furthermore, in step 2, the illumination brightness decreases from 100% to 25% to 45% within 0.8s to 1.0s, and is maintained for 3.5s to 5s. Research has found that the time it takes for the brightness to decrease from high to low, and the duration of illumination at low brightness, are key factors in enabling involuntary blinking and active adjustment of the eye axis. Under the synergistic effect of a reasonably selected range of low brightness, eye comfort can be effectively improved, eye fatigue relieved, and the eyes protected, thus reducing or preventing myopia. However, adjusting the brightness from high to low too quickly will cause an adaptive effect on the human eye. The eye cannot adjust its axis in time because the adaptation time of vision to changes or switching in light intensity, or the adaptive conditioned reflex of vision to external sensory input, will prevent the eye axis from changing, making it impossible to actively adjust the eye axis, thus hindering the relief of eye fatigue and the reduction or prevention of myopia. However, adjusting the brightness value too slowly from high to low will not achieve the desired transition from static to dynamic light, significantly reducing the effectiveness in relieving eye fatigue and failing to provide adequate eye protection. In step 2, the time for the brightness value to decrease from high to low can be 0.8s, 0.9s, or 1s. The illumination time for the low brightness value in step 2 can be 3.5s, 4s, 4.5s, or 5s.

[0038] Furthermore, in step 1, the brightness value increases to 100% within 0.8s to 1.0s. Research has found that the time it takes for the brightness value to drop from low to high, and the duration of illumination at high brightness, are key factors in enabling involuntary blinking and active adjustment of the eye axis. These are necessary conditions for effectively improving eye comfort, relieving eye fatigue, protecting the eyes, and reducing or preventing myopia. However, adjusting the brightness value too quickly from low to high will cause an adaptive effect on the human eye, leaving insufficient time for the eye to adjust its axis. This is because the adaptation time of human vision to changes in light intensity or switching between light and dark, or the adaptive conditioned reflex of vision to external sensory input, will prevent the eye axis from changing, making it impossible to actively adjust the eye axis and thus hindering the relief of eye fatigue and the reduction or prevention of myopia. Conversely, adjusting the brightness value too slowly will also fail to achieve the transition from static to dynamic light, significantly reducing the effect of relieving eye fatigue and failing to achieve good eye protection benefits. For example, in step 1, the time for the low brightness value to rise to the high brightness value can be 0.8s; 0.9s; or 1s.

[0039] Furthermore, in step 2, the brightness value increases to 100% within 0.8s to 1.0s. Research has found that the time it takes for the brightness value to drop from low to high, and the duration of illumination at high brightness, are key factors in enabling people to blink unconsciously and actively adjust their eye axis. These are necessary conditions for effectively improving eye comfort, relieving eye fatigue, protecting the eyes, and reducing or preventing myopia. However, adjusting the brightness value too quickly from low to high will cause an adaptive effect on the human eye, leaving insufficient time for the eye to adjust its axis. This is because the adaptation time of human vision to changes in light intensity or switching between light and dark, or the adaptive conditioned reflex of vision to external sensory input, will prevent the eye axis from changing, making it impossible to actively adjust the eye axis and thus hindering the relief of eye fatigue and the reduction or prevention of myopia. Conversely, adjusting the brightness value too slowly will also fail to achieve the transition from static to dynamic light, significantly reducing the effect of relieving eye fatigue and failing to achieve good eye protection benefits. For example, in step 2, the time for the low brightness value to rise to the high brightness value can be 0.8s; 0.9s; or 1s.

[0040] Furthermore, in step 1, the total time for the entire brightness value change is 16s to 20s, and in step 2, the total time for the entire brightness value change is 16s to 20s. Research has found that even if the switching time during the brightness conversion process is met, the total time of the entire brightness adjustment process is a key factor affecting the eye protection effect. The time of the entire brightness adjustment process should not be too long or too short; otherwise, it will significantly reduce eye comfort and have a poor effect on reducing or preventing myopia. For example, the total illumination time is 16s; 17s; 18s; 19s; 20s.

[0041] Furthermore, the 100% luminance value is not less than 600 Lux, and the 25%–45% luminance value is not greater than 400 Lux. Choosing an appropriate brightness can increase human comfort and relieve eye fatigue. Preferably, the 100% luminance value is not less than 800 Lux, and the 25%–45% luminance value is not greater than 300 Lux. More preferably, the 100% luminance value is not less than 800 Lux, and the 25%–45% luminance value is 150–300 Lux.

[0042] Furthermore, the highest color temperature value is less than or equal to the color temperature value of the high color temperature light source group, and the lowest color temperature value is greater than or equal to the color temperature value of the low color temperature light source group.

[0043] Furthermore, the difference between the highest and lowest color temperature values ​​should be ≤3000K. When the difference between the highest and lowest color temperature values ​​is large, the comfort of the human eye can be effectively guaranteed during lighting, relieving eye fatigue and achieving the effect of reducing or preventing myopia.

[0044] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0045] 1. This invention discloses a full-color bionic eye-protection desk lamp, comprising a support cover, a main board, and a folding panel; the main board is fixedly connected to the support cover, and the folding panel is hinged to the main board; the folding panel can rotate around the main board to a certain angle and then be locked, and can also be released and rotated around the main board to fit against the main board; an LED light source component is provided on the surface of the folding panel near the main board, and the light source of the LED light source component is a full-color bionic light source; it also includes an LED driving device, which is electrically connected to the LED light source component, and the LED driving device can drive the current of the LED light source component to change, so as to achieve changes in lighting brightness and / or color temperature value. First, the full-color bionic eye-protection desk lamp provided by this application allows the folding panel to be fixed around the main board to fit against the main board when not in use, and the folding panel can be locked after rotating around the main board to a certain angle when in use. The structure is simple, easy to use, and easy to store. Meanwhile, the full-color bionic eye-protection desk lamp provided in this application forms a high-saturation red light and a high-saturation cyan light existence mode in the spectrum of the lighting source. Based on the imaging principle of color on the retina, the full-color bionic light source helps to adjust the focal length and axial length of vision during visual imaging, realize the visual imaging of object color reproduction, ensure high visual adaptability and comfort, and effectively relieve eye fatigue under lighting.

[0046] 2. This invention divides the LED light source component into a high color temperature light source group and a low color temperature light source group. The high color temperature light source group is composed of high color temperature light source arrays, and the low color temperature light source group is composed of low color temperature light source arrays. The arrangement of the high color temperature light source arrays and the low color temperature light source arrays is specifically adjusted. By adjusting the current ratio passing through the low color temperature light source group and the high color temperature light source group, the change in illumination color temperature value can be adjusted. By simultaneously adjusting the magnitude of the current I1 of the low color temperature light source group and the magnitude of the current I2 of the high color temperature light source group, the change in illumination brightness can be adjusted. By adjusting the coordination of the changes in illumination color temperature value and brightness, the human eye can be involuntarily blinked, and the eyeball can automatically refocus and reset, thereby actively adjusting the axial length of the eye and preventing the axial length of the eye from increasing.

[0047] 3. The lighting method of the full-color bionic eye-protection desk lamp provided by the present invention includes the following steps: Step 1: The lighting source gradually changes from the highest color temperature value to the lowest color temperature value. During the color temperature change process, the lighting maintains a constant 100% brightness value, and the color temperature change time is 10s to 14s; then, while maintaining the lowest color temperature value, the lighting brightness value decreases from 100% brightness value to 25% to 45% brightness value within 0.8s to 1.1s, and the lighting is maintained for 3s to 5s; then, the brightness value rises to 100% brightness value within 0.8s to 1.1s; Step 2: The lighting source gradually changes from the lowest color temperature value to the highest color temperature value. During the gradual change of color temperature, the illumination maintains a constant 100% brightness value, with the color temperature change lasting 10-14 seconds. Then, while maintaining the highest color temperature value, the illumination brightness decreases from 100% to 25%-45% within 0.8-1.1 seconds, and is maintained for 3-5 seconds. Afterward, the brightness value rises back to 100% within 0.8-1.1 seconds. Step 3: Repeat steps 1-2 to perform cyclic illumination. In step 1, the total illumination time is 15-20 seconds, and in step 2, the total illumination time is 15-20 seconds. Throughout the lighting process, by coordinating the changes in color temperature and brightness, the system completes the transition from high to low brightness and from low to high brightness within a specific timeframe during the gradual color temperature change. This transforms static light into dynamic light while avoiding visual adaptation. By specifically adjusting the brightness and color temperature of the lighting source during the lighting process, and under excellent lighting conditions, the system mimics the natural changes in brightness, effectively "resetting" the eye's active adjustment of the eye axis. This causes the eye to blink unconsciously, and the active adjustment of the eye axis conforms to visual habits, thereby achieving the effects of protecting the eyes, reducing eye fatigue, and alleviating or preventing myopia.

[0151] Test conditions: 8:30-11:30 AM, 2:00-4:30 PM, and 7:00-9:00 PM daily; after 9 PM, go to bed, close the curtains, and use a desk lamp as the only light source to read.

[0152] During reading, take a 15-minute break every 45 minutes. During this short break, go outdoors and enjoy the view.

[0153] The testing period was 24 weeks, and the changes in vision are shown in Table 2. In Table 2, the effective rate represents the percentage of eyes where the refractive error decreased.

[0154] Six months later, the participants were asked to rate their eye fatigue, with high eye fatigue being a low score and high eye comfort being a high score.

[0155] A high score was set from 0 to 10, where 10 indicates high eye comfort and 1 indicates poor eye comfort. The higher the score, the higher the eye comfort. The test results are shown in Table 2. In Table 2, the effective rate represents the percentage of eyes with a decrease in myopia.

[0156] In Table 1, the visual acuity of high myopia is above 600 degrees, the visual acuity of moderate myopia is between 300 and 600 degrees, and the visual acuity of mild myopia is below 300 degrees.

[0162] As shown in Table 2, the test results of Examples 2-4, using the technical solution of this invention, achieved an eye fatigue relief score of 9.7, with a 100% effective treatment rate for moderate to high myopia and mild myopia, reducing myopia by up to 200 degrees. By specifically adjusting the lighting source and the method of changing the brightness value of the light source during the lighting process, under excellent lighting conditions, the biomimetic brightness changes, effectively "resetting" the eye's active adjustment function of the axial length, causing unconscious blinking. This active adjustment of the axial length conforms to visual habits, thus achieving the effects of protecting the eyes, reducing eye fatigue, and alleviating or preventing myopia. Comparative Examples 1-2, which did not use the full-color biomimetic light source of this application, showed a significantly reduced effect in relieving eye fatigue, and some eyes even experienced an increase in myopia, failing to achieve a good effect in reducing or preventing myopia. Using only conventional lighting sources and methods resulted in varying degrees of increase in myopia, with some non-myopic eyes turning into myopic eyes, indicating poor technical effectiveness.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
