Patent ID: 7847485

Claim:
An aurora generation device for generating aurora by causing electric discharge in a vacuumed chamber comprising: in orthogonal coordinates consisting of X, Y and Z axes; two electrodes each connected to a power source and disposed to face each other in the direction of Z axis, at least one of said electrodes disposed in an X-Y plane and extending linearly in the direction of X axis, said one of said electrodes made of flexible linear member capable of being curved; electric driving means to move said linear member in the direction of Y axis; and coils producing magnetic flux between said two electrodes in the direction of Z axis, wherein said electric driving means moves said linear member in the direction of Y axis to form a curved shape, and wherein electric discharge is caused between said two electrodes and said coils produce magnetic flux between said two electrodes, thereby generating light emission in the form of a curved plane bent toward the direction of Y axis.
