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 0.8s;0.9s;1s;1.1s;1.2s. In the step 1, the illumination time at a low luminance value may be 3.5s,4s,4.5s,5s.

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 0.8s;0.9s;1s;1.1s;1.2s. In the step 2, the illumination time at the low luminance value may be 3.5s,4s,4.5s,5s.

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 1, the time for the low luminance value to rise to the high luminance value may be 0.8s;0.9s;1s;1.1s;1.2s.
Further, in the step 2, the brightness value is increased to 100% within 0.8s to 1.2s. 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 0.8s;0.9s;1s;1.1s;1.2s. Further, in the step 1, the total time total amount of the luminance value change is 14s to 20s, and in the step 2, the total time total amount of the luminance value change is 14s 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 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. The comfort level of people can be improved and the fatigue of eyes can be relieved by selecting proper brightness. Preferably, the brightness value of 100% is not less than 800Lux, and the brightness value of 25% to 45% is not more than 300Lux. More preferably, the brightness value of 100% is not less than 800Lux, and the brightness value of 25% to 45% is 150 to 300Lux.
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.
Furthermore, the difference value between the highest color temperature value and the lowest color temperature value is more than or equal to 1200K. When the difference between the highest color temperature value and the lowest color temperature value is large, the comfort level of human eyes can be effectively ensured, the fatigue of the eyes is relieved, and the effect of reducing or preventing myopia is achieved.
