the processing unit is further configured to increase the intensity of the light beam projection according to a second preset adjustment strategy when the comparison result indicates that the light intensity of the current environment of the electronic device is greater than the reference light intensity;
and when the comparison result represents that the light intensity of the current environment of the electronic equipment is smaller than the reference light intensity, reducing the intensity of the light beam projection according to the second preset adjustment strategy.
