Abstract

A method is provided for improving the illumination of an illuminated area (100), especially an operating area, of an illuminating device (10) with at least two light modules (20). The method includes the emission of an illuminant characteristic of the light module (20) with a preset amplitude from each light module (20). The reflected amplitudes of all characteristic light types are detected. The detected amplitudes for each light module (20) are compared. The light intensity of at least one light module (20) is varied on the basis of the comparison of the detected amplitudes for each light module (20).
