  • Method and apparatus for manufacturing a flat fluorescent lamp
    Patent number: 7749036
    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.
    Type: Grant

  • Flat fluorescent lamp with improved capability of luminance and reduced initial operational voltage
    Patent number: 7659657
    Abstract: A flat fluorescent lamp which can be used with an LCD display includes a plurality of discharge channels. Pairs of electrodes are formed on both ends of the discharge channels. Each of the plurality of channels has an emitting section at the middle, and electrode sections on both ends thereof. A width of the electrode sections is the same as that of the emitting section. However, a height of the electrode sections is greater than a height of the emitting section, resulting in the electrode section having a cross-sectional area that is larger than that of the emitting section.
