  • External electrode fluorescent lamp, back light unit using the external electrode fluorescent lamp, LCD back light equipment using the back light unit and driving device thereof
    Patent number: 7084583
    Abstract: The present invention relates to an external electrode fluorescent lamp which can provide higher degree of and more improved uniformity of brightness than those of conventional ones, and to a LCD back light unit using the external electrode fluorescent lamp. The present invention also relates to an equipment and a driving device to adapt the LCD back light unit. The external electrode fluorescent lamp of the present invention is comprising: an upper panel of lamp which is serpentine shaped; a lower panel which is planar shaped and to be combined with the upper panel to make channels between the upper panel and the low panel; and external electrodes which are located at the two extreme sides at the surface of the upper panel.
