Abstract:
1. A streamer discharge type lightening rod capable of generating lots of ions, comprising: a lightening conducting unit that is formed of a conductive tip at an upper most portion of a lightening rod; a lightening protection unit that is installed at a lower side of the lightening conducting unit and has at least one conical skirt with a lower side of the at least one conical skirt being wider than an upper side of the at least one conical skirt; an insulation unit that is installed at a lower side of the lightening protection unit and is formed of an insulation material on its surface and has an internal portion formed of a metallic material with a current being supplied to the lightening protection unit; and a body that is installed at a lower side of the insulation unit with its lower side being connected with the ground for conducting lightening current to the ground and has an ion generation circuit installed in the interior of the body for generating ions, wherein said ion generation circuit includes: an electric potential generation unit for detecting a magnetic field variation in real time between the ground and thundercloud generated by electrostatic induction when thundercloud is developed and for generating induction current; an energy storing unit for charging electric charge into the interior of the energy storing unit when induction current is generated at the electric potential generation unit with one end of the energy storing unit being connected with the ground, and with the other end of the energy storing unit being connected with the electric potential generation unit; a switching unit that opens the circuit when electric charge is fully charged into the energy storing unit and moves the electric charges of the energy storing unit to an upper side of the lightening rod and closes the circuit when the electric charges are charged into the energy storing unit with one side of the switching unit being connected with the energy storing unit, and with the other side of the switching unit being connected with an upper side of the lightening rod; and an oscillator that amplifies the current inputted as the switching unit is opened and generates a high voltage in the interior of the oscillator and induces the high voltage to the upper most side of the lightening rod with one side of the oscillator being connected with the switching unit, and with the other end of the oscillator being connected with the upper most side of the lightening rod.
