METHOD OF PACKAGING OF FLAT FLUORESCENT LAMP AT THE VACUUM STATE AND VACUUM PACKAGED FLAT FLUORESCENT LAMP USING THE SAME

摘要

Using an O-ring is a flat fluorescent lamp manufactured by a vacuum packaging method and a method of the flat fluorescent lamp in vacuum is disclosed. Vacuum packaging method of the flat fluorescent lamp of the present invention to the back surface substrate and a bottom formed with a discharge electrode to the upper preparing the front substrate phosphor layers formed inlet to the vacuum chamber and a rear substrate via an O-ring on the edge of the rear substrate and after aligning the front substrate by applying pressure between the front substrate and the rear substrate on which the O-ring is compressed between the front substrate and the rear substrate, and thereby vent (vent) of the vacuum chamber. Removing the pressure between the front substrate and the rear substrate, front substrate and the rear substrate is due to the vacuum and external pressure difference between the inside of the front substrate and the rear substrate is a package.
