Abstract: The invention relates to a flat lamp (1) transmitting radiation in the ultraviolet, known as a UV lamp, comprising: first and second flat dielectric walls (2, 3) that are facing each other, kept substantially parallel, and sealed, to one another, thus defining an internal space (10) filled with gas (7), the first dielectric wall at least being made of a material that transmits said UV radiation; electrodes composed of first and second electrodes (4, 5), having different given potentials, for a perpendicular discharge between the walls, the first electrode at least being based on a layer arranged in order to allow overall UV transmission; and an emitting gas or a phosphor coating (6) on one main inner face (22, 32) of the first and/or the second dielectric wall (2, 3), the phosphor emitting said UV radiation by being excited by the gas. The invention also relates to the uses thereof and to the manufacture thereof.

Abstract: The present invention relates to a flat discharge lamp (1000) that transmits in the visible and/or UV comprising first and second dielectric walls (2, 3) that are facing each other, kept parallel and sealed at the periphery (8), that thus define an internal space (10) filled with a plasma gas and comprising a source of UV and/or visible light (6); and first and second electrodes (4, 5) in separate planes parallel to the first and second walls, the first electrode (4) being at a potential V0 higher than the potential V1 of the second electrode, and the first electrode being arranged in the internal space and closer to the first dielectric wall than the second electrode.
