SIGN OR DECORATION

摘要

The abstract is a sign or a decorative article made from a sheet of dielectric material with first and second components made of electrically conductive material in contact one with each side of the dielectric material; the components of electrically conductive material are not in electrical contact with each other and are connectable to different terminals of an electric power supply; when power is supplied to the electrically conductive components, the sign produces a glowing corona effect.
