Flat fluorescent lamp and structure of the same

Abstract

A flat fluorescent lamp structure comprises a first substrate, a second substrate assembled to the first substrate to form a sealed space, at least one wall dividing the sealed space into a plurality of illuminating chambers filled with a discharge gas, wherein two terminals of each the illuminating chamber are mounted with two outside electrodes respectively for generating an electrical current through the illuminating chamber. At least one tunnel is formed therethrough to communicate the illuminating chambers. A phosphor layer is formed on a plurality of inner surfaces of the illuminating chambers, wherein the tunnel extends along a tilt direction relative to the illuminating chamber, and therebetween the entire tilt direction and the illuminating chamber form an acute angle. The entire tilt direction is formed by a first end of the tunnel directly connected with the illuminating chamber and a second end of the tunnel directly connected with another illuminating chamber adjacent to the illuminating chamber.
