Abstract

The invention relates to a method for determining a distance from a sensor to a luminaire. The luminaire includes at least a first light source configured to emit a first light beam adapted to illuminate a predefined area and a second light source configured to emit a second light beam adapted to illuminate a background area surrounding the predefined area. The sensor which could e.g. be included within another luminaire is configured to detect a back reflected first light beam and a back reflected second light beam. The method includes determining the distance from the sensor to the luminaire based at least partially on a comparison of information indicative of a signal strength of the detected back reflected first light beam and information indicative of a signal strength of the detected back reflected second light beam.
