Abstract

A method for improving the illumination of an illumination region (100), in particular of an operation region, from an illumination device (10), includes at least two light modules (20) and at least one sensor device (30) for detecting depth information. The method includes the steps of monitoring a monitored volume (110) between the light modules (20) and the illumination region (100), identifying the position and the geometry as object data of at least one object (200) within the monitored volume (110), comparing the identified object data with beam paths (S) from the light modules (20), and modifying the light intensity of at least one light module (20) on the basis of the comparison between the identified object data with beam paths (S) from the light modules (20).
