Abstract: An illuminating method for illuminating a specific region S and peripheral regions Ca, Cb thereof by a plurality of light sources 10a, 10b, wherein the light sources 10a, 10b have mutually different flicker frequencies, and their irradiation areas Ia, Ib overlap each other in the specific region S, thus causing an observer to perceive in the specific region S a flicker stimulation having a frequency different from the flicker frequencies of light perceived by the observer in the peripheral regions Ca, Cb where the irradiation areas do not overlap each other.
