ABSTRACT:
Disclosed are a neon light utilizing a flat plate electrode and a lower plate structure employed in the neon light. In the neon light, an advertisement pattern is expressed by means of discharge spaces formed by carving out one or both of two insulation plates, the upper and lower plates. Therefore, the discharge spaces are integrally formed at the upper plate and/or the lower plate. Further, the electrodes for the electric discharge, which are formed at the upper and lower electrodes, utilize flat plate electrodes. The phosphor elements in the discharge space are excited, so as to emit visible rays to the exterior. Therefore, the present invention decreases the discharge voltage and increases the brightness, while facilitating the manufacture of the neon light.
