step 1, the illumination light source is gradually changed from a highest color temperature value 5600K to a low color temperature value 3000K, and the illumination brightness value is 900Lux unchanged in the color temperature gradual change process; color temperature gradual change duration 12s; then, maintaining the lowest color temperature value, wherein the illumination brightness value is within 0.8s from 900Lux, and the brightness value is reduced to 270Lux, and maintaining illumination for 4s; then the brightness value is increased to 900Lux within 0.8 s;

step 3, gradually changing the illumination light source from a lowest color temperature value of 3000K to a highest color temperature value of 5600K, wherein in the color temperature gradual change process, the illumination brightness value of 900Lux is unchanged; the color temperature gradual change duration is 12s; then, keeping the highest color temperature value unchanged, and keeping illumination brightness within 0.8s from 900Lux, wherein the brightness value reduced to 270Lux, and keeping illumination for 4s; then the brightness value is increased to 900Lux within 0.8 s;

and step 3, repeating the steps from the step 1 to the step 2, and circularly illuminating.

In the whole illumination process, through adjusting the cooperation of illumination color temperature value change and brightness change, in the color temperature gradual change process, accomplish the switching of high brightness to low brightness and the switching of low brightness to high brightness in specific time, become the static light into dynamic light, can avoid the self-adaptation of vision simultaneously, through the simultaneous variation of the light source brightness and the color temperature of pertinence adjustment illumination light source and illumination in-process, the bionical attitude change luminance under excellent light source illumination, realize "reset" the initiative regulation eye axis function of people's eye, let the unconscious blink, and initiative regulation eye axis accords with vision habit, thereby can reach the effect of protecting eyes, slowing down eye fatigue, alleviate or prevent myopia.
