Description

An LED lamp with adjustable eye axis and its use method

This application claims priority to the Chinese patent application filed with the China Patent Office on November 21, 2022, with application number 202211453336.4 and invention name “A LED lamp with adjustable eye axis and method of use thereof”, the entire contents of which are incorporated by reference into this application.

Technical Field

The present application relates to the field of eye protection lighting, and specifically to an LED lamp with adjustable eye axis and a method of using the same.

Background technique

The human eye was formed and evolved under natural lighting conditions, and the adaptability of vision to natural light is irreplaceable. As shown in Figure 1, when the eyes look at pure blue light, the eyes will open wider unnaturally, so that the image of the blue light falls on the retina; when the eyes look at pure red light, the eyes will squint unnaturally, so that the image of the red light falls on the retina. There is a lack of red light spectrum and too much blue light spectrum in the ordinary artificial lighting spectrum. After long-term use of the eyes, it can not only damage the retinal macular area, but also easily cause "eye fatigue" and form myopia.

At present, the research on full-spectrum lighting has received extensive attention because the amount of blue light is reduced and the red light spectrum is increased in the spectrum. However, the common full-spectrum in the prior art still has the problem of more blue light spectrum and less red light spectrum. The approximation of the radiation power distribution curve of the light source in the full spectrum to the natural spectrum of the same color temperature can only reach about 80% at most. Red light stimulates long-wave sensitive cones, slows down axial elongation, and prevents animals from moving from hyperopia to emmetropia, so that the eyes always remain hyperopic. The most significant anatomical changes are the reduction of vitreous cavity elongation, the forward movement of the retina toward the cornea, and the increase in choroidal thickness, which also moves the retina forward, which to a certain extent will produce a significant response to optical focusing. When red light is applied to emmetropia, the hyperopic effect produced by red light can delay the further elongation of the eye axis, which has a certain effect on preventing the development of myopia. Therefore, strengthening the red light spectrum in the full spectrum and weakening the blue light spectrum are of great significance in reducing eye fatigue and preventing myopia.

Furthermore, when the human eye is reading or writing, it tends to "concentrate" or "stare at the object being viewed". In this way, after long-term viewing, the eyes will be fixed for a long time and the eyes will be easily fatigued, especially when the red light spectrum is missing in the luminous light color, the eyes will easily cause the eye axis to lengthen and produce myopia if they look at the object for a long time. In order to solve the above problems, for example, Chinese patent CN108743268A discloses glasses and methods of use that use light intensity to exercise eyeball muscles to prevent and treat myopia or presbyopia, and discloses the principle of spectral adjustment of eye axis to prevent and treat myopia and hyperopia. However, this scheme is similar to the function of a light feeding instrument, and uses a combination of multiple white light sources to achieve a natural spectrum. The fundamental problem is the lack of red light spectrum, and it is impossible to achieve visual real imaging of the object's restored color. Another journal "Study on the short-term effects of full-spectrum white light of different illumination on the human eye axis, Sichuan Medicine 2020.01.24" discloses the conclusion that full-spectrum white light of different intensities will have an impact on the eye axis. However, neither of them discloses how to adjust the brightness to achieve active adjustment of the eye axis without causing the eyes to adapt. Therefore, it is of great significance to develop an eye protection lighting method that can well realize an adjustable eye axis method that conforms to visual habits to protect the eyes, relieve eye fatigue, and reduce or prevent myopia.

technical problem

The purpose of the present application is to provide an LED lamp with adjustable eye axis and a method of using the same, in view of the problem that the eyes are easily fatigued after long-term viewing when the human eye is reading or writing, especially when the light source lacks red light or the red light spectrum is weak, which can easily lead to the elongation of the eye axis and the occurrence of myopia. The lighting method of the present application adopts a full-color bionic light that is highly fitted with natural light as the lighting light source, and provides independent dimming bionic visual control during the lighting process, turning static light into dynamic light. The spectrum remains unchanged when the brightness changes and does not cause visual adaptation, so that the eyes blink and the eyeballs focus and reset autonomously, thereby achieving active adjustment of the eye axis in line with visual habits, while protecting the eyes, alleviating eye fatigue, and reducing or preventing myopia.

Another purpose of the present application is to provide a method for using the above-mentioned LED lamp with adjustable eye axis.

A method for using the above-mentioned LED lamp with adjustable eye axis 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 gradient process, the lighting maintains a 100% brightness value, and the color temperature gradient duration is 6s to 18s. Then, the lowest color temperature value is maintained, and the lighting brightness value decreases from 100% brightness value to 25% to 45% brightness value within 0.5s to 2s, and the lighting is maintained for 2s to 6s. After that, the brightness value rises to 100% brightness value within 0.5s to 2s.

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 100% brightness value, and the color temperature gradual change time is 6s to 18s; then the highest color temperature value is maintained unchanged, and the lighting brightness decreases from 100% brightness value to 25% to 45% brightness value within 0.5s to 2s, and the lighting is maintained for 2s to 6s; then the brightness value rises to 100% brightness value within 0.5s to 2s;

Step 3, repeating the steps of step 1 to step 2 to perform cyclic lighting; wherein in step 1, the total lighting time is 12s to 22s, and in step 2, the total lighting time is 12s to 22s.

The present application discloses a method for using an LED lamp with an adjustable eye axis. First, the illumination light source adopted is a full-color bionic light source. The spectrum of the full-color bionic light source is a spectrum whose radiation power distribution curve is 95%±5% similar to the natural spectrum of the same color temperature, and the spectral color rendering index of the full-color bionic light source is greater than 95, wherein the color rendering indexes R1 to R15 are all greater than 90. The spectrum of the illumination light source forms an existence mode of highly saturated red light and highly saturated cyan light. According to the imaging principle of color on the retina, the full-color bionic light source helps to adjust the visual focal length and eye axis during visual imaging, realizes visual imaging of objects with restored colors, ensures high adaptability and comfort of vision, and effectively relieves eye fatigue under lighting. At the same time, the lighting method provided by the present application includes the following steps: step 1, the lighting light source gradually changes from the highest color temperature value to the lowest color temperature value, and during the color temperature gradient process, the lighting maintains a 100% brightness value unchanged, and the color temperature gradient time is 6s to 18s; then, the lowest color temperature value is maintained unchanged, and the lighting brightness value is reduced from 100% brightness value within 0.5s to 2s to 25% to 45% brightness value so that the illumination of the illuminated object surface is 150lim to 300lim, and the lighting is maintained for 2s to 6s; then the brightness value is increased to 100% brightness value within 0.5s to 2s; step 2, the lighting light source is changed from the lowest color temperature value to the lowest color temperature value. The temperature value gradually changes to the highest color temperature value. During the gradual change, the lighting maintains a 100% brightness value unchanged, and the color temperature gradual change time is 6s to 18s; then the highest color temperature value is maintained unchanged, and the lighting brightness decreases from 100% brightness value to 25% to 45% brightness value within 0.5s to 2s, and the lighting is maintained for 2s to 6s; thereafter, the brightness value rises to 100% brightness value within 0.5s to 2s; step 3, repeating the steps of step 1 to step 2 for cyclic lighting; wherein in step 1, the total lighting time is 12s to 22s, and in step 2, the total lighting time is 12s to 22s. During the entire lighting process, by adjusting the coordination of lighting color temperature changes and brightness changes, in the process of color temperature gradient, the switching from high brightness to low brightness and from low brightness to high brightness is completed within a specific time, turning static light into dynamic light, and at the same time avoiding visual adaptation. By targetedly adjusting the lighting source and the simultaneous changes in light source brightness and color temperature during the lighting process, under excellent light source illumination, the ecological change in brightness is simulated to "reset" the human eye's active adjustment of the eye axis function, making people blink unconsciously, and actively adjusting the eye axis in line with visual habits, thereby protecting the eyes, alleviating eye fatigue, and reducing or preventing myopia.

Furthermore, in step 1, the time for the illumination light source to gradually change from the highest color temperature value to the lowest color temperature value is 6s to 16s. For example, 6s; 7s; 8s; 9s; 10s; 11s; 12s; 13s; 14s; 15s; 16s.

Furthermore, in step 2, the time for the illumination light source to gradually change from the lowest color temperature value to the highest color temperature value is 6s to 16s. For example, 6s; 7s; 8s; 9s; 10s; 11s; 12s; 13s; 14s; 15s; 16s.

Further, in the step 1, the illumination brightness is reduced from 100% brightness value to 25% to 45% brightness value within 0.5s to 1.5s, and the illumination is maintained for 2s to 5s. Studies have found that the time when the high brightness value is reduced to the low brightness value and the illumination time of the low brightness value are both key factors for realizing people's unconscious blinking and actively adjusting the eye axis, and under the synergistic effect of the reasonable selection range of the low brightness value, it can effectively improve the comfort of the eyes, relieve eye fatigue, protect the eyes, and achieve the effect of reducing or preventing myopia. Among them, adjusting the high brightness value to the low brightness value too quickly will produce an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis, because the adaptive time length of the vision or the adaptive conditioned reflex of the vision to the external sense under the change or switching of light and dark light will cause the eye axis to not change, and it is impossible to achieve active adjustment of the eye axis, and it is difficult to achieve the effect of relieving eye fatigue and reducing or preventing myopia. However, adjusting the high brightness value to the low brightness value too slowly will not have the effect of the transition from static light to dynamic light, and the effect of relieving eye fatigue will be significantly worse, and good eye protection effect cannot be achieved. In step 1, the time for the high brightness value to decrease to the low brightness value can be 0.5s; 0.6s; 0.7s; 0.8s; 0.9s; 1s; 1.1s; 1.2s; 1.3s; 1.4s; 1.5s. In step 1, the lighting time of the low brightness value can be 2s, 3s; 4s, 5s.

Furthermore, in step 2, the lighting brightness is reduced from 100% brightness value to 25% to 45% brightness value within 0.5s to 1.5s, and the brightness is maintained at 100%. Maintain lighting for 2s to 5s. Studies have found that the time it takes for a high brightness value to drop to a low brightness value, as well as the lighting time of a low brightness value, are key factors in achieving unconscious blinking and active adjustment of the eye axis. In combination with a reasonable selection range of low brightness values, it can effectively improve eye comfort, relieve eye fatigue, protect the eyes, and achieve the effect of reducing or preventing myopia. Among them, adjusting the high brightness value to a low brightness value too quickly will have an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis, because when human vision changes or switches between light and dark, the adaptive time length of vision or the adaptive conditioned reflex of vision to the external senses will cause the eye axis to not change, and it will be impossible to actively adjust the eye axis, and it will be difficult to relieve eye fatigue and achieve the effect of reducing or preventing myopia. However, adjusting the high brightness value to a low brightness value too slowly will not have the effect of transitioning from static light to dynamic light, and the effect of relieving eye fatigue will be significantly worse, and good eye protection cannot be achieved. In step 2, the time for the high brightness value to decrease to the low brightness value can be 0.5s; 0.6s; 0.7s; 0.8s; 0.9s; 1s; 1.1s; 1.2s; 1.3s; 1.4s; 1.5s. In step 2, the lighting time of the low brightness value can be 2s, 3s; 4s, 5s.

Further, in the step 1, the brightness value rises to 100% brightness value within 0.5s to 1.5s. Studies have found that the time from the low brightness value to the high brightness value and the lighting time of the high brightness value are key factors for realizing unconscious blinking and actively adjusting the eye axis, which can effectively improve the comfort of eye use, relieve eye fatigue, protect the eyes, and achieve the necessary conditions for reducing or preventing myopia. Among them, adjusting the low brightness value to the high brightness value too quickly will produce an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis, because the adaptive time length of the vision or the adaptive conditioned reflex of the vision to the external sense under the change or switching of light and dark light will cause the eye axis to not change, and it is impossible to actively adjust the eye axis, and it is difficult to achieve the effect of relieving eye fatigue and reducing or preventing myopia. However, adjusting the low brightness value to the high brightness value too slowly will not have the effect of converting static light to dynamic light, and the effect of relieving eye fatigue will be significantly worse, and good eye protection effect cannot be achieved. For example, in step 1, the time for the low brightness value to rise to the high brightness value can be 0.5s; 0.6s; 0.7s; 0.8s; 0.9s; 1s; 1.1s; 1.2s; 1.3s; 1.4s; 1.5s.

Further, in step 2, the brightness value rises to 100% brightness value within 0.5s to 1.5s. Studies have found that the time from the low brightness value to the high brightness value and the lighting time of the high brightness value are key factors for realizing unconscious blinking and actively adjusting the eye axis, which can effectively improve the comfort of eye use, relieve eye fatigue, protect the eyes, and achieve the necessary conditions for reducing or preventing myopia. Among them, adjusting the low brightness value to the high brightness value too quickly will produce an adaptive effect on the human eye, and the human eye will not have time to adjust the eye axis, because the adaptive time length of the vision or the adaptive conditioned reflex of the vision to the external sense under the change or switching of light and dark light will cause the eye axis to not change, and it is impossible to actively adjust the eye axis, and it is difficult to achieve the effect of relieving eye fatigue and reducing or preventing myopia. However, adjusting the low brightness value to the high brightness value too slowly will not have the effect of converting static light to dynamic light, and the effect of relieving eye fatigue will be significantly worse, and good eye protection effect cannot be achieved. For example, in step 2, the time for the low brightness value to rise to the high brightness value can be 0.5s; 0.6s; 0.7s; 0.8s; 0.9s; 1s; 1.1s; 1.2s; 1.3s; 1.4s; 1.5s. Furthermore, in step 1, the total time of the entire brightness value change is 12s to 20s, and in step 2, the total time of the entire brightness value change is 12s to 20s. Studies have found that even if the switching time in the brightness conversion process is met, the total time in the entire brightness adjustment process is also a key factor affecting the eye protection effect. The time in the entire brightness adjustment process is not easy to be too long or too short, otherwise it will significantly reduce the comfort of the eyes, and the reduction or prevention of myopia will be poor. For example, the total lighting time is 12s; 13s; 14s; 15s; 16s; 17s; 18s; 19s; 20s.

Furthermore, the brightness value of 100% is not less than 600 Lux, and the brightness value of 25% to 45% is not greater than 400 Lux. Selecting the appropriate brightness can increase people's comfort and relieve eye fatigue. Preferably, the brightness value of 100% is not less than 800 Lux, and the brightness value of 25% to 45% is not greater than 300 Lux. More preferably, the brightness value of 100% is not less than 800 Lux, and the brightness value of 25% to 45% is 150 to 300 Lux.

Furthermore, the highest color temperature value and the lowest color temperature value are two different color temperature values within the range of 2700K to 5600K.

Further, the highest color temperature value and the lowest color temperature value are at least two of 2700K-3000K, 4000K-4200K, 4700K-5200K and 5500K-6000K. Preferably, the lowest color temperature value is 2700K-3000K, and the highest color temperature value is 5500K-6000K.

Furthermore, the highest color temperature value is ≤ the color temperature value of the high color temperature light source group, and the lowest color temperature value is ≥ the color temperature value of the low color temperature light source group.

Spectral power: The spectrum emitted by a light source is often not a single wavelength, but a mixed radiation of many different wavelengths. The spectral radiation of a light source in the order of wavelengths and the distribution of the intensity of each wavelength is called the spectral power distribution of the light source.
