The invention relates to an aircraft beacon device installed on a high structure, preferably on a tower of a wind power installation, and comprisin g a least one luminous means and at least one switching device that switches said luminous means. The aim of the invention is to improve an aircraft beac on device of wind power installations and, in particular, to design the operati on thereof to be as effective as possible. To this end, the aircraft beacon device installed on a high structure, preferably on a wind power installatio n, and comprising at least one luminous means mounted on the structure is provided with a device for detecting the brightness value, e.g. a twilight switch. Said device for detecting the brightness value detects the brightnes s of day in the surroundings of the structure and is connected to a switching device, which evaluates the measured data and switches on the aircraft beaco n when a defined brightness value is fallen below of. |
