Description

LED lamp with adjustable eye axis and use method thereof

Technical Field

The invention relates to the field of eye protection illumination, in particular to an LED lamp with an adjustable eye axis and a using method thereof.

Background

The human eye is formed and evolved in a natural lighting environment, and the adaptability of vision to natural light is irreplaceable. As shown in fig. 1, when the eye looks at pure blue light, the eye may look wide and the image of the blue light falls on the retina; when the eyes see pure red light, the eyes can see a little bit unnaturally, so that the red light image is on the retina. The problems of lack of red light spectrum and over-high blue light spectrum exist in the common artificial lighting spectrum, and after the artificial lighting spectrum is used for a long time, the yellow spot area of retina can be injured, eye fatigue can be easily caused, and myopia is formed.

At present, full spectrum illumination is widely focused on due to the fact that blue light quantity is reduced in the spectrum, and red light spectrum is increased. However, the common full spectrum in the prior art still has the problems of more blue light spectral quantity and less red light spectral quantity, and the approximation degree of a light source radiation power distribution curve in the full spectrum and a natural spectrum with the same color temperature can only reach about 80% at most. The red light can stimulate long-wave sensitive cone cells, slow down axial elongation, prevent animals from going from hyperopia to emmetropia, and enable eyes to keep hyperopia all the time. The most significant anatomical changes are a decrease in vitreous chamber elongation, an anterior movement of the retina toward the cornea, an increase in choroidal thickness, and an anterior movement of the retina, which in part produces a pronounced response to optical focusing. When the red light is applied to the emmetropic eye, the hypermetropia effect generated by the red light can delay the continuous extension of the eye axis, and the effect of preventing the development of myopia is achieved. Therefore, the strengthening of the red light spectrum in the full spectrum and the weakening of the blue light spectrum have very important significance for reducing eye fatigue and preventing myopia.

Furthermore, when people look at books or write, people often stare at the object to be viewed by concentrating spirit or keeping eyes away, so that after long-time vision, the eyes are focused for a long time, the eyes are easy to be tired, and especially in the light emitting color, when the red light spectrum is lost, the eyes look long for the object, the axes of the eyes are easy to be lengthened, and myopia is caused. In order to solve the above problems, for example, chinese patent CN108743268a discloses glasses for training eye muscles with light intensity to prevent and treat myopia or presbyopia and a using method thereof, and discloses a principle of spectrum adjusting axis to prevent and treat myopia and hypermetropia, but the scheme is similar to the function of a light supplying instrument, and adopts a combination of a plurality of white light sources to realize natural spectrum, and there is a fundamental problem that the red light spectrum is absent, and real visual imaging of an object with color restored cannot be realized. In another journal, "short-term impact of full spectrum white light with different illuminance on the human eye axis" research, in Sichuan medicine 2020.01.24, "discloses a conclusion that full spectrum white light with different intensity can affect the eye axis. But neither discloses how to adjust the brightness to achieve active eye-axis adjustment and does not create a situation for the human eye to adapt. Therefore, it is very important to develop an eye protection illumination method which can well realize the eye axis adjustment method according with the visual habit to protect eyes, relieve eye fatigue and reduce or prevent myopia.

Meanwhile, the illumination method provided by the application comprises the following steps: step 1, gradually changing the highest color temperature value of an illumination light source to the lowest color temperature value, keeping the brightness value of 100% of illumination unchanged in the color temperature gradual change process, and setting the color temperature gradual change time to be 6-18 s; then, keeping the lowest color temperature value unchanged, reducing the illumination brightness value from 100% to within 0.5 s-2 s to 25% -45% to enable the illumination of the surface of the illuminated object to be 150 lim-300 lim, and keeping illumination for 2 s-6 s; then the brightness value is within 0.5 s-2 s and is increased to 100 percent brightness value; step 2, gradually changing the illumination light source from the lowest color temperature value to the highest color temperature value, wherein in the gradual change process, the illumination keeps the brightness value of 100 percent unchanged, and the gradual change time of the color temperature is 6-18 s; then keeping the highest color temperature value unchanged, reducing the illumination brightness from 100% brightness value within 0.5 s-2 s to 25% -45% brightness value, and keeping the illumination for 2 s-6 s; then the brightness value is within 0.5 s-2 s and is increased to 100 percent brightness value; step 3, repeating the steps from the step 1 to the step 2, and performing circulating illumination; wherein in the step 1, the total amount of the illumination time is 12 s-22 s, and in the step 2, the total amount of the illumination time is 12 s-22 s. In the whole lighting process, through the cooperation of adjusting the change of lighting color temperature value and luminance change, in the color temperature gradual change process, accomplish the switching of hi-lite to the low luminance and the switching of low luminance to hi-lite in specific time, change static light into dynamic light, can avoid the self-adaptation of vision simultaneously, change when having adjusted light source and the light source luminance and the color temperature in the lighting process through pertinence, under the illumination of excellent light source, imitative ecological change luminance, realize the initiative adjustment eye axis function of "resetting" people's eyes, let the involuntary blink of people, and the initiative adjustment eye axis accords with the vision habit, thereby can reach the effect of protecting eyes, slow down eye fatigue, alleviate or prevent myopia.

Further, in the 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; for 16s.

Further, in the 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; for 16s.

Further, in the step 1, the illumination brightness is reduced from the 100% brightness value within 0.5s to 1.5s to the brightness value of 25% to 45%, and the illumination is maintained for 2s to 5s. Researches show that the time for reducing the high brightness value to the low brightness value and the illumination time of the low brightness value are key factors for realizing the involuntary blinking of people and actively adjusting the eye axis, and under the synergistic effect of the reasonable selection range of the low brightness value, the eye comfort can be effectively improved, the eye fatigue can be relieved, the eyes can be protected, and the effect of reducing or preventing the myopia can be realized. The high brightness value is adjusted to the low brightness value too fast, a self-adaptive effect can be generated on eyes, the eyes cannot adjust the eye axis, the eye axis cannot be changed due to the fact that human vision changes or is switched between light and dark light, the self-adaptive time length of the vision or the self-adaptive conditioned reflex of the vision on external perception can result in the fact that the eye axis cannot be changed, active adjustment of the eye axis cannot be achieved, eye fatigue cannot be relieved, and the effect of reducing or preventing myopia is achieved. However, if the high brightness value is adjusted to the low brightness value too slowly, the effect of converting static light into dynamic light cannot be achieved, the effect of relieving eye fatigue is obviously poor, and a good eye protection effect cannot be achieved. In the step 1, the time for reducing the high luminance value to the low luminance value may be 0.5s;0.6s;0.7s;0.8s;0.9s;1s;1.1s;1.2s;1.3s;1.4s;1.5s. In the step 1, the illumination time with a low brightness value can be 2s,3s;4s and 5s.

Further, in the step 2, the illumination brightness is reduced from the 100% brightness value within 0.5s to 1.5s to the brightness value of 25% to 45%, and the illumination is maintained for 2s to 5s. Researches show that the time for reducing the high brightness value to the low brightness value and the illumination time of the low brightness value are key factors for realizing the involuntary blinking of people and actively adjusting the eye axis, and under the synergistic effect of the reasonable selection range of the low brightness value, the eye comfort can be effectively improved, the eye fatigue can be relieved, the eyes can be protected, and the effect of reducing or preventing the myopia can be realized. The high brightness value is adjusted to the low brightness value too fast, a self-adaptive effect can be generated on eyes, the eyes cannot adjust the axis of the eyes, the self-adaptive time length of the vision or the self-adaptive conditioned reflection of the vision to the outside perception can result in no change of the axis of the eyes under the change or switching of light and dark light of the vision, the axis of the eyes can not be adjusted actively, the eye fatigue is difficult to relieve, and the effect of relieving or preventing myopia is achieved. However, if the high brightness value is adjusted to the low brightness value too slowly, the effect of converting static light into dynamic light cannot be achieved, the effect of relieving eye fatigue is obviously poor, and a good eye protection effect cannot be achieved. In the step 2, the time for reducing the high brightness value to the low brightness value may be 0.5s;0.6s;0.7s;0.8s;0.9s;1s;1.1s;1.2s;1.3s;1.4s;1.5s. In the step 2, the illumination time with a low brightness value can be 2s,3s;4s and 5s.

Further, in the step 1, the brightness value is increased to 100% brightness value within 0.5s to 1.5s. Researches show that the time for reducing the low brightness value to the high brightness value and the illumination time of the high brightness value are key factors for realizing the involuntary blinking of people and actively adjusting the eye axis, and the key factors are necessary conditions for effectively improving the comfort degree of eyes, relieving eye fatigue, protecting eyes and realizing the reduction or prevention of myopia. Wherein, too fast adjust low luminance value to high luminance value, can produce self-adaptation effect to the eyes, the eyes of people are too late to adjust the axis of the eye, because people's vision is under light and shade light change or switching, the self-adaptation time length of vision or the self-adaptation conditioned reflex that the vision is to external perception can lead to the axis of the eye can not produce the change, can't realize initiatively adjusting the axis of the eye, are difficult to realize alleviating eye fatigue to realize alleviating or preventing near-sighted effect. However, if the low brightness value is adjusted to the high brightness value too slowly, the effect of converting static light into dynamic light cannot be achieved, the effect of relieving eye fatigue is obviously poor, and a good eye protection effect cannot be achieved. For example, in step 1, the time for the low luminance value to rise to the high luminance value may be 0.5s;0.6s;0.7s;0.8s;0.9s;1s;1.1s;1.2s;1.3s;1.4s; for 1.5s.

Further, in the step 2, the brightness value is increased to 100% brightness value within 0.5s to 1.5s. Researches show that the time for reducing the low brightness value to the high brightness value and the illumination time of the high brightness value are key factors for realizing the involuntary blinking of people and actively adjusting the eye axis, and the key factors are necessary conditions for effectively improving the comfort degree of eyes, relieving eye fatigue, protecting eyes and realizing the reduction or prevention of myopia. The low brightness value is adjusted to the high brightness value too fast, a self-adaptive effect can be generated on eyes, the eyes cannot adjust the eye axis, the eye axis cannot be changed due to the fact that human vision is changed or switched between light and dark light, the self-adaptive time length of the vision or the self-adaptive conditioned reflex of the vision on external perception can result in the fact that the eye axis cannot be changed, active adjustment of the eye axis cannot be achieved, eye fatigue cannot be relieved, and the effect of reducing or preventing myopia is achieved. However, if the low brightness value is adjusted to the high brightness value too slowly, the effect of converting static light into dynamic light cannot be achieved, the effect of relieving eye fatigue is obviously poor, and a good eye protection effect cannot be achieved. For example, in step 2, the time for the low luminance value to rise to the high luminance value may be 0.5s;0.6s;0.7s;0.8s;0.9s;1s;1.1s;1.2s;1.3s;1.4s; for 1.5s. Further, in the step 1, the total time total amount of the luminance value change is 12s to 20s, and in the step 2, the total time total amount of the luminance value change is 12s to 20s. Research finds that even if the switching time in the brightness conversion process is met, the total time in the whole brightness adjustment process is also a key factor influencing the eye protection effect, the time in the whole brightness adjustment process is not easy to overlong or too short, otherwise, the eye comfort level can be obviously reduced, and the myopia is reduced or prevented badly. For example, the total illumination time is 12s;13s;14s;15s;16s;17s;18s;19s; and 20s.

Furthermore, the brightness value of 100% is not less than 600Lux, and the brightness value of 25% -45% is not more than 400Lux.

More preferably, the brightness value of 100% is not less than 800Lux, and the brightness value of 25% to 45% is 150 to 300Lux.
