Patent ID: 7495168

Claim:
An electric dipole streamer discharge type lightning conductor, which includes: a body connected at a lower portion thereof to the earth and allowing electric currents of a thunderbolt to flow to the earth when the falling of a thunderbolt occurs; a thunderbolt receiving part being a conductive tip and located at the uppermost end of the body; an insulating part having an insulating material layer coated with on the surface thereof to prevent electric charges of the earth from being transferred to the outside of the insulating material layer; and a discharge inducing part having one end fixed to the surface of the insulating material layer and the other end spaced apart from the body for gathering electric charges in the atmospheric air to the surface thereof, wherein the discharge inducing part includes: a first discharge inducing part formed in a conical shape, in such a way that one end thereof is fixed on the insulating material layer of the insulating part and the other end thereof is spaced apart from the body, the first discharge inducing part having at least one groove formed on the surface thereof to gather a great deal of negative (−) electric charges in the atmospheric air; and a second discharge inducing part formed in a semi-conical shape correspondingly to the first discharge inducing part and spaced apart from the first discharge inducing part, the second discharge inducing part having one end fixed on the body and the other end spaced apart from the body to gather a great deal of positive (+) electric charges in the earth, whereby when thunderclouds are formed, the first discharge inducing part carries out a dielectric breakdown due to an air gap formed by potential differences between the first discharge inducing part and the spaced body and between the first discharge inducing part and the spaced second discharge inducing part.
