Lighting elements in which at least one light source is arranged to the side of a fluorescent panel are known; the light emanating from the light source is collected in the fluorescent panel and emitted at its edge. In comparison, the novel lighting element is intended to permit a planar emission of light and at the same time to be of a particularly simple and compact design. In the case of the novel lighting element, the light source comprises a sheet-like luminous capacitor (3) with an electroluminescent dielectric (12), which is arranged in surface contact with the fluorescent panel (2); the luminous capacitor (3) and the fluorescent panel (2) form the lighting element (1) in a multilayered arrangement. The novel lighting element is suitable in particular for the line-by-line illumination of originals in optical scanning devices. <IMAGE>
