Claims18
A method for operating obstacle or hazard lighting of a wind power plant, comprising:
- providing a red beacon unit and a white beacon unit;
- operating the red beacon unit 24 hours a day, wherein the red beacon unit is controlled such that the red beacon unit is switched on 24 hours a day;
- and
- switching on and off the white beacon unit depending on ambient brightness,
- wherein a light intensity of the red beacon unit is reduced over certain time periods.
2 more elements
A wind power plant, comprising:
- obstacle or hazard lighting including red beacon lamps and white beacon lamps;
- a brightness sensor detecting an ambient brightness in a vicinity of the wind power plant and producing a brightness signal representing a detected ambient brightness;
- and
- a control device connected to the brightness sensor for receiving the brightness signal, the control device being configured to control a switching on and off of the beacon lamps based upon the brightness signal,
- wherein the control device is configured such that the red beacon unit is switched on 24 hours a day and the white beacon unit is switched on and of depending on the detected ambient brightness, and
- wherein the control device is configured such that a light intensity of the red beacon unit is reduced over certain time periods by the control device.
