Patent number: 6903503Abstract: 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.Type: GrantFiled: August 20, 2001Date of Patent: June 7, 2005Assignee: Grand Display, Inc.Inventor: Hong-Ju Ha

Publication number: 20030009923Abstract: The present invention relates to a neon sign device having a plain shape. The neon sign device having the plain shape according to the present invention comprises an upper glass sheet having electric discharge electrodes installed on its bottom surface; and a lower glass sheet attached closely to the bottom surface of the upper glass sheet and having an electric discharge space where an advertisement pattern to be represented is formed into a cavity. The neon sign device is generally made by bonding the upper and lower glass sheets after forming the electric discharge electrodes and the cavity in the upper and lower glass sheets, respectively. A fluorescent layer is also formed inside the cavity, and inert electric discharge gas is filled inside the cavity. For example, the cavity is formed by engraving it on a portion of a top surface of the lower glass sheet.Type: ApplicationFiled: August 7, 2002Publication date: January 16, 2003Inventor: Hong-Ju Ha
