FLAT FLUORESCENT LIGHT FOR BACKGROUND LIGHTING AND LIQUID CRYSTAL DISPLAY DEVICE FITTED WITH SAID FLAT FLUORESCENT LIGHT

摘要

The invention relates to a flat fluorescent light (1) having a discharge vessel (2) comprising a base plate (7), a cover plate (8) and a frame (9) forming a gastight soldered connection. Structures resembling strip connectors act as electrodes (3-6) inside the discharge vessel. Said structures also act as conductors in the conductor area and as external electricity inlets (13; 14) on the outside. This configuration enables simple and easily automated manufacturing of flat lights in different sizes. Moreover, an almost infinite variety of electrode shapes can be made, specially with regard to creating a homogenous and optimized light density with reduced density loss on the edges of said light. At least the anodes (5, 6) are covered by a dielectric coating (15). Preferably, the light (1) is operated by pulse voltage source and is used for background lighting of LCD's, e.g. in monitors or diver information displays.
