Beschreibung
Zusammenfassung:	A rotor blade for use in a wind energy system is provided with the rotor blade having a rotor blade body comprising a rotor blade body tip; a rotor blade body cavity; and a lightning protection unit. The lightning protection unit includes a conductive part that is connected to a down conductor and positioned within the rotor blade body cavity close or at the rotor blade body tip, the conductive part having an extension protruding out of the rotor blade body for receiving a receptor. According to another aspect of the invention, a wind energy system is provided with at least one of such a rotor blade. Further, a method for constructing a rotor blade for use in a wind energy system is provided with the steps of manufacturing a pressure side shell and a suction side shell of the rotor blade; applying a conductive part to an inner side of the pressure side shell or the suction side shell with the conductive part including a body and an extension; and forming the rotor blade by joining the pressure side shell and the suction side shell together in such a way that the body of the conductive part is in the rotor blade and the extension of the conductive part protrudes out of the rotor blade.
