Claim 0:
1. A wind turbine blade assembly, comprising:
a wind turbine blade having a blade root for connection to a hub of a wind turbine;
an assembly tip, which is either formed by a blade tip of the wind turbine blade or an add-on tip of a wind turbine blade add-on attached to the blade tip of the wind turbine blade, wherein the wind turbine blade assembly spans a length from the blade root to the assembly tip; and
a lightning protection system comprising an internal down conductor inside the wind turbine blade and multiple air termination devices having at least one receptor, which is electrically conductively coupled to the down conductor;
wherein the length of the wind turbine blade assembly is divided into a first part spanning from the blade root to at least one first air termination device, in which the internal down conductor extends, and a second part spanning from the first air termination device to the assembly tip, in which the internal down conductor is absent;
wherein the lightning protection system further comprises:
at least one second air termination device in the second part, and
at least one external, electrically conductive strip extending at least between the first air termination device and the second air termination device in the second part and being electrically conductively coupled to receptors of the first air termination device and the second air termination device.
