Abstract

Disclosed is a lighting arrangement () comprising a lighting device () having an adjustable luminous output; a control arrangement () communicatively coupled to the dimmable lighting device including a controller () adapted to adjust the luminous output of the lighting device a data storage device accessible by the controller storing calibration data for a light measurement device of a mobile communication device, the calibration data being a function of a distance between the mobile communication device and the lighting device and a communication module () communicatively coupled to the controller, wherein the control arrangement is adapted to control the lighting device such that the lighting device produces a predefined luminous output; receive a luminous output measurement from the mobile communication device at an unknown distance from the lighting device; retrieve distance information regarding the distance between the mobile communication device and the lighting device from the calibration data based on the received luminous output measurement; and adjust the luminous output of the lighting device with the controller in accordance with the retrieved distance information. A computer program product, mobile communication device and lighting system are also disclosed.
