Abstract

Leuchte zur Beleuchtung einer Nutzfläche (N) mit einer Beleuchtungseinheit (1), einer Sensorik (2) und einer Steuerungseinheit (3). Die Beleuchtungseinheit (1) emittiert wenigstens ein Erfassungslichtspektrum, und die Sensorik (2) erfasst das von der Nutzfläche (N) und/oder auf der Nutzfläche (N) liegenden Objekten jeweils reflektierte Lichtspektrum, um eine dominierende Farbe aus dem wenigstens einen reflektierten Lichtspektrum zu bestimmen. Als Erfassungslichtspektrum werden nacheinander ein Grünlichtspektrum und ein Blaulichtspektrum emittiert. Anschließend wird der Lichtanteil im Wellenlängenbereich von 450 nm des reflektierten Blaulichtspektrums BS verglichen mit dem Lichtanteil im Wellenlängenbereich von 530 nm des reflektierten Grünlichtspektrums BS, wobei Rot als die dominierende Farbe bestimmt wird, wenn der Lichtanteil im Wellenlängenbereich von 450 nm größer ist als der Lichtanteil im Wellenlängenbereich von 530 nm, und sonst Gelb als dominierende Farbe bestimmt wird.
