Abstract

A light detector arranged to determine a daylight contribution and an artificial light contribution to a combined illumination level wherein the artificial light comprises individual light coding modulation. The detector comprises: - a photo-sensor arranged to detect the illumination level at its position, and generate an illumination signal; and - a calculator, connected with the photo-sensor for receiving the illumination signal, and arranged to calculate the daylight contribution and the artificial light contribution and output corresponding daylight and artificial light signals. The calculator comprises: - an electronic filter arranged to prepare the illumination signal for estimation of the daylight and artificial light contributions; - a daylight part and an artificial light part, respectively connected to the electronic filter. The artificial light part comprises an artificial light DC component estimator, and the daylight part comprises a total DC component estimator, and a subtractor connected to the total DC component estimator and to the artificial light DC component estimator, and being arranged to determine the daylight contribution as the difference between their outputs. The artificial light DC component estimator is arranged to include present luminaire dimming level data and modulation depth data regarding the light coding modulation in a basis of its estimation.
