Abstract: A lighting element for illuminating a component of a wind power installation, in particular a rotor blade and/or a rotor and/or a tower and/or a nacelle. A component for a wind power installation, in particular a rotor blade and/or a rotor and/or a nacelle and/or a tower for a wind power installation. A wind power installation and a method for illuminating a component of a wind power installation. The lighting element comprises a lighting portion and a connection portion, wherein the connection portion is embodied and arranged to be connected in an interior of the component and the lighting portion is arranged and embodied to protrude from an opening of the component and the lighting portion is arranged and embodied to irradiate the component from which it protrudes.

Abstract: A method for lightning warning with a large number of wind energy installations, in particular with a part of a wind farm, wherein the wind energy installations are each located at one location, and each of the large number of wind energy installations comprises a sensor arrangement for registering an environmental parameter, comprising at least an anemometer, a temperature sensor and/or a humidity sensor, wherein the sensor arrangement comprises a further sensor, in particular an electric field meter for registering electric fields, and the method comprises the following steps, namely a registration of at least one value for the environmental parameter, comprising at least an electric field, with the aid of the sensors of the sensor arrangement with the large number of wind energy installations; and an evaluation of the at least one value for the environmental parameter for the prediction of the lightning warning for the locations of the large number of wind energy installations.
