A method for influencing light propagation directions of a light-emitting surface emitting light of a first wavelength range in a first direction and light of a second and wavelength range in a second direction. The wavelength ranges have a wavelength-dependent spectral radiance and differ in a peak wavelength. A switchable color converter is arranged in front of the light-emitting surface. The method includes the steps of a) deactivating the color converter for a first mode so that the second-wavelength range is transmitted and the first-wavelength range is absorbed, such that light from the light-emitting surface is only perceptible from the second direction, or b) activating the color converter for a second mode so that light of the first-wavelength range is converted into light of the second-wavelength range and light of the second-wavelength range is transmitted, such that light from the light-emitting surface is perceptible from both directions.
