An optimized lightning rod comprises a rod body and a base. The rod body includes a main rod and auxiliary rods which are arranged on a lightning receptor. The lightning receptor is arranged on the base. The base is provided with screw holes. The base is connected with a current limiting impedor, and the current limiting impedor is arranged on the base. The main rod is arranged in the center of the lightning receptor, and the four auxiliary rods are arranged around the lightning receptor. The lightning receptor is connected with the base through threads. The main rod is higher than the auxiliary rods. The whole lightning rod is made of stainless steel metal. As the main rod and the auxiliary rods are arranged for the rod body, the scope of protection is greatly enhanced. The whole lightning rod is made of stainless steel metal, so that the lightning rod has the advantages of corrosion resistance, high wind resistance and long service life, and can actively trigger lightning and effectively avoid the damage of secondary lightning to building areas. Moreover, the lightning rod is novel in structure, beautiful in shape, simple to install and suitable for promotion.
