Problems solved by technology

Due to the high temperature in the furnace during the exhaust process, the property of the glass to expand in all directions prevents the exhaust pipe made of glass from maintaining the original position of the exhaust pipe, thus causing the exhaust pipe to break

Embodiment Construction

[0038] [Preparation of fluorescent lamp]

[0039] The preparation of the fluorescent lamp used in the present invention will now be described.

[0040] Fig. 3 is an exploded perspective view illustrating the separation of the first substrate and the second substrate in a plane. Fig. 4 is an exploded perspective view illustrating the assembly of the first substrate and the second substrate in a vertical position.

[0041] 3, there is provided a first molded substrate 12, that is, a rectangular upper lamp plate, and a second molded flat substrate 14, that is, a lower lamp to be attached to the lower surface of the first substrate 12 board. The surface of the first substrate 12 has a plurality of long corrugated regions 13A, which are arranged parallel to each other in one direction to form a preliminary gap for the discharge channel 16. The surface of the first substrate 12 additionally has a first corrugated area 13B, which is connected to one side surface of the outermost corrugat...

Abstract

Provided are an apparatus and a method for manufacturing a flat fluorescent lamp. The fluorescent lamp includes a plurality of discharge channels, a gas inlet connecting to the discharge channels, and an exhaust pipe connecting to the gas inlet. The process for manufacturing the fluorescent lamp includes exhausting air from the discharge channels through the exhaust pipe, diffusing a mercury vapor within the discharge channels, blocking a passage between the gas inlet and the most outer channel, and removing the gas inlet and the exhaust pipe.

Description

Technical field [0001] The present invention relates to fluorescent lamps, and more particularly, to a method and apparatus for preparing flat fluorescent lamps. Background technique [0002] In particular, fluorescent lamps are widely used to prepare backlight elements for liquid crystal devices (LCD). Generally speaking, fluorescent lamps have various shapes, including linear, serpentine, flat, and so on. At high temperatures, glass is molded into various shapes of the lamp to form a discharge channel inside the lamp. [0003] The inner surface of the discharge channel is coated with fluorescent material and kept in a vacuum. An exhaust process is used to keep the discharge channel in a vacuum. At a high temperature, for example, 400° C., an exhaust process is performed in a furnace (not shown) to remove impurities such as moisture and moisture present in the discharge channel. After the exhaust process is completed, inert gas and mercury vapor are supplied to the discharge c...
