A flat lamp structure is disclosed. The flat lamp structure includes a gas
discharge chamber, a fluorescence substance, a discharge gas, and a
plurality of electrodes. The fluorescence substance is disposed on the
inner wall of the gas discharge chamber, and the discharge gas is
disposed in the gas discharge chamber. The electrodes are disposed on the
outer wall of the gas discharge chamber, wherein the gas discharge
chamber comprises a dielectric substrate, a plate, and a plurality of
rods, and the plate is disposed on the upper portion of the dielectric
substrate and the rods are disposed between the plate and the dielectric
substrate, and the plate and the edge of dielectric are connected.
Additionally, the gas discharge chamber, for example, can dispose with at
least a spacer to enhance the strength of the gas discharge chamber.
