MERCURY FREE FLAT LUMINESCENT LAMP CAPABLE OF LOWERING THE DISCHARGE STARTING VOLTAGE BY INCREASING AN EMISSION AREA

摘要

PURPOSE: A mercury free flat luminescent lamp is provided to improve the effectiveness by forming a reflective film on first and second electrodes which are partitioned and formed in a lower glass substrate.;CONSTITUTION: An upper glass substrate(111) and a lower glass substrate(112) face each other. A sealant(120) is combined in the side of the upper and the lower glass substrates. A first electrode(131) is formed in a longitudinal direction in one end of the lower glass substrate. A second electrode(132) is formed in a longitudinal direction in the other end which is separated with the first electrode as much as 50~80mm. A reflective film(140) is laminated on the first and the second electrode. At least one auxiliary electrode(150) is formed between the first electrode and the second electrode. The reflective film is composed of Al2O3 and simultaneously executes a role as the reflective film and the dielectric. The auxiliary electrode is formed by being separated from the gap between the first and the second electrode as much as 2~4mm.;COPYRIGHT KIPO 2010
