A beacon, especially for a wind turbine, comprising a support structure; at least two different LED units circumferentially mounted thereon and directed outwardly and alternating in a circumferential direction, with emitted light of first and second ones of the LED units differing with respect to their spectral compositions and being activatable separately from one another; and a linear lens disposed outwardly of the LED units, extending the circumferential direction, and serving to bundle light emitted from the LED units, with the linear lens being shared by all of the LED units. |
